Molecular basis underlying high-yield and superior-quality traits and breeding elite rice varieties by molecular design

Rice is one of the world's most important crops, playing an important role in national food security. Although tremendous progresses have been made in developing high-yield and good-quality rice varieties over past decades, it is still a time-consuming and labor-consuming process at present in improving yield- and quality-related traits by traditional breeding approaches, because of the complexity of these traits and lacking the knowledge of how these traits are regulated and coordinated. Therefore, it is the national benefit and strategy to develop a powerful and effective system for breeding high-yield and good-quality elite rice varieties by dissecting the genetic network that regulates important agronomic traits and making full use of the natural variation of rice germplasm resources.

To meet the challenges that aims at addressing the fundamental questions and to meet the national needs, this project collaboratively integrated technologies of genetics, genomics, molecular biology, biochemistry, cell biology, and crop breeding to systemically investigate molecular mechanisms of these important agronomic complex traits and to effectively evaluate their application potentials in molecular breeding. In the past 13 years, the project had made ground-breaking progresses by cloning key genes involved in important agronomic traits, dissecting molecular mechanisms underlying these complex traits, utilizing elite germplasm resources and genome-wide association analysis, understanding the origin and domestication of Asian cultivated rice, and breeding high-yield and superior-quality rice varieties by molecular design. This project also systemically analyzes rice cooking and eating quality that is mainly determined by a genetic network of the starch synthesis pathway, paving an avenue and providing important genetic resources for the improvement of rice quality by molecular design. Moreover, this project developed a series of algorithm for genome-wide associate analysis and precise detection of the genetic loci that control complex agronomic traits, innovating the genetic dissection of complex agronomic traits. By identifying the genetic variations between indica and japonica rice varieties, scientists in this project have revealed the genetic basis of the reproductive isolation between the two subspecies, providing a new insight into the utilization of rich rice genetic resources and playing a vanguard role in developing a molecular design technology in rice.

The creative achievements and original findings made in this project have resulted in a series of joint publications in the top scientific journals including Nature, Nature Genetics, PNAS, and Plant Cell, which have been widely and positively cited and reviewed in many original research papers and review articles, with more than 4800 SCI citations for their joint published papers and over 1900 SCI citation for the 8 selected representative papers. Both Jiayang Li and Bin Han were awarded in 2014 by Thomson Reuters as the “highly cited researcher” and "world's most influential scientists" in the category of Plant and Animal Sciences based on their publications from 2002-2012. As recognized by the academic community, the scientists in this project have been invited to write review articles for Annual Review Plant Biology, Annual Review Genetics, Nature Genetics, Trends Genetics, Current Opinion in Plant Biology, and frequently invited as plenary and keynote speakers in the international academic congresses, conferences and symposia. Notably, their achievements regarding "The molecular mechanism underlying rice ideal plant architecture" and "The strigolactone signaling pathway and their roles in regulating rice tillering" were elected as “the Nation’s Top ten Scientific Breakthroughs in China" in 2010 and 2014, respectively. More importantly, they have demonstrated how to translate the knowledge from basic research to applied technology and then to agricultural production, paving an applicable way for upgrading breeding efficiency from understanding and mining gene regulating important traits to breeding new elite varieties by molecular design.

Aggregation-induced emission

Many organic fluorophores emit strongly in dilute solutions, but demonstrate decreased or no emission concentrated solution or the aggregate state. This “aggregation-caused quenching” (ACQ) effect results in low emission efficiency of organic fluorophores in the solid state, and is detrimental to their device performance. Scientists have tried different strategies to prevent chromophore aggregation, but only limited results were obtained. In this project, a natural aggregation process, named aggregation-induced emission (AIE), was utilized to elevate the solid-state emission efficiency of organic fluorophores, through which original and creative results have been achieved. The main scientific discoveries in the project are summarized as followings:
1. Based on previously proposed AIE mechanism of restriction of intramolecular rotation (RIR), the achievers developed new tetraphenylethene (TPE)-cored AIE luminogens (AIEgens), discovered room temperature phosphorescence of organic crystalline fluorophores, put forward the concept of crystallization-induced phosphorescence, and prepared TPE-containing AIE-active polytriazoles with excellent processability by their developed click polymerizations. Moreover, interesting AIE-active polymer systems without conventional chromophores were also reported.
2. Through elaborate molecular design and careful experimental verification, RIR rather than E/Z isomerization or J-aggregation was proved to be the underlying mechanism for the AIE. A sub-concept of AIE, that is, crystallization-induced emission was proposed, which was well recognized by researchers worldwide. New strategies to create AIEgens from ACQ molecules by conjugation with AIE moieties, and generate efficient red emissive AIEgens by combination of RIR and twisted intramolecular charge-transfer processes were invented.

3. Blue/deep-blue AIEgens used in OLEDs were obtained through sensible molecular design. An array of sensing applications, such as quantitative fluorescence turn-on detection of carbon dioxide and metal ions, specific detection of D-glucose, and monitoring of the growth of a specific cell line were realized, which all exhibit the superiority over conventional fluorophores.

With the accomplishment of this project, 1 Chinese and 2 USA patents were issued. The 8 representative papers, all ranked as ESI highly cited papers, have been cited by others for 3469 times, and the highest citation for a single paper is 1285 times. Tang was listed as ESI highly cited Scientist in chemistry and materials fields, elected to the member of Chinese Academy of Sciences in 2009, and won the Hong Kong Croucher Senior Research Fellowship and the National Natural Award both in 2007. Tang has delivered 72 invited talks, including 17 plenary/keynote lectures in the domestic and international academic conferences, and chaired two AIE international symposiums, held in 2013 and 2015, respectively. Special issues on AIE have been published in Small [2016, 47(12)], Science China Chemistry [2013, 56(9)] and Acta Chimica Sinica [2016, 74(11)], and monographs on AIE were also published by Wiley in 2013.

In summary, the AIE provides a new avenue for the design of luminescent materials and fluorescent sensors, and innovates our design principle for light-emitting materials, enriches the fundamentals of photo-physics, and creates a new research field in chemistry and materials sciences, in which Chinese scientists take the lead, followed by the scientists all over the world.

Some Analysis Problems in Differential Geometry

The project belongs to Geometric Analysis which is an interdisciplinary of Differential Geometry and Partial Differential Equations and a hot important research field in pure mathematics. The main results are as follows:

Constructed a new evolution equation and used the mean curvature flow to prove the existence of closed minimal surfaces (paper 1 and 5). How to find closed minimal surfaces and holomorphic curves is important and many problems are unsolved. The project constructed a new evolution equation to study the existence of closed minimal surfaces in Riemannian manifolds. They showed that, in the Torus case, the new flow does not produce complicated singularities, obtained the global weak solution and its convergence.Recently, Topping and his coauthor generalized it to higher genus case.  The project used the mean curvature flow to study the existence of minimal surfaces in a K-E surface. They proved that, if the initial surface is symplectic, the mean curvature flow has no Type I singularity (Wang M.-T. proved it independently), under some assumptions they proved the global existence and convergence.

Blow-up formula for stationary harmonic maps (paper 2, 3 and 4). This is an important and difficult subject in geometric analysis and nonlinear analysis. Energy minimizing maps are compact (Schoen-Uhlenbeck), if the target has no harmonic spheres stationary harmonic maps are also compact (F.-H. Lin). The project constructed a weakly convergence sequence of stationary harmonic maps whose limit is not stationary. In general, stationary harmonic maps are not compact. The project studied the blow-up behavior of a weakly convergence sequence of stationary harmonic maps in the general case, proved a blow-up formula for the weak limit and the blow-up set, which implies that the weak limit is stationary if and only if the blow-up set is stationary. The project also proved that the energy identity holds for a sequence of maps from a Riemann surface to a sphere with tension fields bounded in L Log L. Topping and his coauthor generalized the compactness and pointed out that the space L Log L can not be improved to local Hardy space.

3) In the case of lack compactness, found a minimum of the functional, and obtained the existence theorem of Kazdan-Warner problem (paper 6 and 7). The problem is raised in 1974 (Ann Math), related to Moser-Trudinger inequality , is interesting and difficult. The results and analysis method were used by other authors, cited by others 66, 81 times.

4) Proved the Donaldson
Uhlenbeck-Yau theorem in non-compact cases and the Chern number inequality on parabolic stable bundlespaper 8. The result and other results are used to study the parabolic stable bundles further.

The results were published in Invent Math, Comm Pure Appl Math, Adv Math, etc. Academician Tian Gang, academician of American Academy of Sciences, Chang, S. introduced the work in her ICM plenary speak. The results were used by the plenary speaker of ICM, Mochizuki (Japan Academy Prize winner) and ICM invited speaker Topping
Malchiodi. ICM invited speaker Lin Chang-Shou (Academician of Academia Sinica) and Li Yanyan highly appreciate it.

Doping mechanism of semiconductors

Doping is a key technology in modern semiconductor industry. This project focuses on the band structure characters of wide-band-gap semiconductor materials, two-dimensional materials, and nano devices. We systemically investigated the doping mechanism and predicted the properties of several important semiconductor materials. We developed first-principles based algorithm for large-scale calculations, and applied it to doped semiconductor systems and two-dimensional semiconductors. Our results are valuable for the p-type doping technology of the third generation semiconductors, for the improvement of the photocatalysis efficiency of TiO2 based materials, and for the fabrication of semiconductor spintronic devices and 2D devices in the future. The main results of the projects are as follows:
1. By analyzing the band structure of TiO2 and the chemical potentials of the dopants, we propose that the band edges of TiO2 can be modified by passivated codopants such as (Mo+C) to shift the valence band edge up significantly, while leaving the conduction band edge almost unchanged. Such a method enhances the adsorption to visible light in TiO2, and maintains its photocatalysis ability. This work attracts world-wide attentions, and recent experimental studies have verified the feasibility of Mo+C co-doping. The paper was cited for 360 times.
2. We systemically studied the origin of “d0 ferromagnetism”. We further demonstrated that localization of the holes by dopants and quantum confinement effect can reduce the critical hole concentration for stabilizing magnetization. These findings suggest new possibility of preparing non-magnetically doped spintronic semiconductor devices. The paper was cited by 232 times.
3. We systemically studied the doping character and bottleneck of dopant and acceptor impurities in quantum dots and quantum wires. We show that due to quantum confinement, the transition energies and defect formation energies of defects always increase as the quantum dot sizes decrease, leading to the self-purification. We proposed the method to solve such doping bottleneck, and developed a model to describe the quantum Stark effect in hole impurity state of quantum dots. These works promoted the research in the application of nano devices. The related paper was cited for 106 times.
4. We predicted the type-II band alignment in MoX2-WX2 heterostructures. Moreover, we studied the mechanical, optical properties and band gap modulation of graphyne, and discovered that Ca-doped graphyne had high capacity of hydrogen storage. Lastly we found direct-indirect gap transition and semiconductor-metal transition in strained MoS2.
The project attracted great attentions, and the related works are highly cited by researchers all over the world. The 8 representative papers have been cited by 1344 times, and 5 of them are selected as ESI highly cited papers. 6 related invention patents have been issued.  Parts of the work was selected as “research highlight” by NPG Asia Materials, and two papers published in Physical Review Letters in 2009 were selected as “Most influential papers of China, 2009”. These works are the developments of semiconductor doping theory, and have important scientific value for the device design and property prediction of new generation semiconductors and nano-devices.

Raman Spectroscopy of Low-dimensional Carbon Materials

Low-dimensional carbon materials, including carbon nanotubes and graphene, are strategic materials that will dominate the high-tech competition and play a core role in future semiconductors, micro/nano-electronics and energy. The in-depth studies of their fundamental structures and properties are essential for the possible breakthroughs in frontier and original research. Raman spectroscopy has played an important and irreplaceable role in the research of low-dimensional carbon materials.

Structure-property relationship and reactivity regularity of organic compounds

Discovery of new reactions drives the advance of organic chemistry, during which elucidation of the reaction mechanism and origin of reaction selectivity constitutes one of the core targets of organic chemistry. Studies in this direction contributes to the understanding of the principles of organic reactions and motivates the collaborative innovation of experimental and theoretical chemistry. This project involves systematic studies focusing on structure-property relationship of organic compounds and their reactivities in organic reactions. These studies led to the development of several physical chemistry theories including the enthalpy-entropy compensation theory, the polarized cluster continuum solvation model for organic solvents, and the free energy equations for the redox potentials in organic solutions. On the basis of these theoretical advances, especially the solvation models in organic solvents, we carried out theoretical studies to clarify the reaction mechanism and the origin of reaction selectivity in the conversions of carbon−carbon, carbon−hetero and carbon−metal bonds. Inspired the mechanistic understandings and predictions from the theoretical studies, we were successful in developing an array of new organic reactions such as decarboxylative cross-coupling and radical-controlled selective C−H functionalization reactions. The representative scientific achievements are summarized as follows:

1. Development of physical organic chemistry theories, including enthalpy-entropy compensation theory based on the transition of species of equivalent chemical potentials, the polarized cluster continuum solvation model for organic solvents, and the free energy equations for the redox potentials in organic solutions.

2. Elucidation of the mechanisms and the selectivity of C-C, C-X, and C-M transformation reactions, including 1) elucidation of the mechanism of nickel-catalyzed C-O activation in cross-coupling of aryl esters and explanation of the selectivity of aryl C-O and carbonyl C-O activation; 2) elucidation of the origin of chemoselectivity in copper catalyzed arylation of aminoalcohols; 3) elucidation of the mechanism of decarboxylative Heck-coupling of carboxylic acid and olefins

3. Development of an array of new organic reactions. Important examples include: 1) palladium-catalyzed decarboxylative coupling between potassium oxalate monoester salts and aryl halides; 2) copper-catalyzed trifluoromethylation reactions.

The above studies were published in about 100 papers in the international peer-reviewed journals, including 15 papers in J. Am. Chem. Soc., 8 papers in Angew. Chem. Int. Ed., and 1 in Chem. Rev. These achievements have drawn broad attentions in the world and have been recognized by different research groups. Eight representative papers have been cited by others for 1473 times. Over 50 invited presentations have been given at the international conferences.

Basic Research on New Molecular Ferroelectrics

As a type of advanced materials, ferroelectric materials are used in various devices. Since the first ferroelectric Rochelle salt was found in 1920, the phase transition temperature (Tc) and saturation polarization (Ps) of molecule-based ferroelectrics have been long beat by the well-known inorganic ceramic ferroelectric such BaTiO3. Under supports from NSFC, the team has carried out systematic studies on the development of the field of molecule-based ferroelectrics in the past 10 years from the assembly of noncentro-symmetric coordination polymers to the screening and characterizations of molecule-based ferroelectrics. As one of the main international contributors to the area, the team has afforded an effective semi-empirical approach to find and design series of new molecule-based ferroelectrics which greatly enrich the family of this type of functional molecular materials.

The primary academic contributions include:

(1) Finding a series of organic ferroelectrics with high Tc and large Ps.

The most important achievement is the finding of the ferroelectric diisopropylammonium chloride and bromide that have high Tc, large Ps and low coercive field (Ec) which are superior to the widely used polymeric ferroelectric PVDF and comparable with BaTiO3. This is the key step toward practical applications of molecule-based ferroelectrics. Meanwhile, they have advantages on cheapness, easy availability, simple preparation and so on. All these make them have the potential to be applied or used as a supplement to conventional ferroelectric oxides and polymers.

(2) Constructing novel ferroelectric and dielectric metal-organic frameworks.

By using in situ solvo-thermal approaches, the team successfully constructed metal complexes with noncentrosymmetric structures, including the first captured tetrazole intermediates that are hard to trap by conventional methods as reported by Sharpless and the tetrazole-based coordination polymers. Their nonlinear, dielectric and potential ferroelectric properties were systematically studied.

(3) Finding and designing two types of ferroelectric molecular rotors.

The team successfully prepared new ferroelectric molecular rotors based on crown ether-phenylammonium derivatives and protonated 1,4-diazacyclo[2,2,2]octane compounds. Their ferroelectricities come from the rotating-frozen transitions of the rotator components. This study discloses the close relationship between ferroelectricity and molecular machines.

(4) Proposing first a semi-empirical approach to guide the exploration of new molecule-based ferroelectrics.

The team first introduced the use of temperature-dependence of second-order nonlinear coefficient (T-χ(2)) as a judge of the occurrence of symmetry breaking. Furthermore, the team can screen and predict ferroelectric crystals in CCDC by using Curie and Neumann principles to clarify the relationship between super- and sub- groups. These rules avoid the try-and-error approach or serendipity for screening new ferroelectrics.

The research has published dozens of papers, including Science (1), J. Am. Chem. Soc. (10), Angew. Chem. Int. Ed. (3), Phys. Rev. Lett. (3), Adv. Mater. (1), Chem. Soc. Rev. (3) and Chem. Rev. (1). The eight representative papers have been cited 1116 times. The project was awarded as the first-class prize in 2015 of National Natural Science Award of Universities and Colleges of China. Besides, the research on molecule-based ferroelectrics was highlighted by the “editors’ choice” of Science.

New strategies for stereo- and enantioselective direct transformations of aromatic compounds

The transformation of aromatic compounds is among the most fundamental reactions in organic chemistry. However, their direct stereo- and enantioselective transformations are quite limited, and it is of great significance to develop highly efficient, novel, stereo- and enantioselective reactions as well as new concepts. Focusing on these challenging issues, this project presented a novel concept of catalytic asymmetric dearomatization (CADA) and developed a series of novel chiral ligands, sequential catalytic reactions and CADA reactions. The latter were applied in the asymmetric total syntheses of several natural products. These works provide new strategies for the application of aromatic compounds.

The concept of CADA has been widely applied by others. Due to the high energy barrier required to break the aromaticity and facile re-aromatization of the dearomatized product, development of CADA reaction is extremely challenging. In this project, various asymmetric allylic dearomatization reactions were achieved by constructing quaternary carbon center to avoid product re-aromatization. Ir-catalyzed intramolecular allylic dearomatization of indoles/controllable migration of methylene amine group was developed, which corrected the wrong structural assignment in the literature and provided a new mechanistic understanding on intramolecular alkylation of aromatic compounds. Two novel types of chiral phosphoramidite ligands (THQphos and BHPphos) were developed. The active iridacycle is generated via sp2 C−H bond activation, which is different from the reported sp3 C−H bond activation. The high diastereoselectivity and overcoming the “unfavorable ortho effect”offered by these ligands greatly expand the substrate scope for the allylic substitution reaction.

Organocatalytic CADA reactions have been developed. Oxidative dearomatization of phenols/chiral Brønsted acid-catalyzed asymmetric Michael addition reactions led to concise and efficient total syntheses of natural products such as cleroindicin and (-)-mesembrine. Organocatalytic cascade dearomatization of indoles was accomplished to construct polycyclic compounds bearing multiple chiral centers rapidly.

Chiral phosphoric acid catalyzed highly enantioselective Friedel-Crafts reactions of indole and 4,7-dihydro-1H-indole with N-sulfonylimine and nitro olefin were achieved. Sequential catalysis by combining Ru complex with chiral phosphoric acid, with synergistic effect (“1+1>2”), was developed to afford highly enantioselective synthesis of polycyclic indoles. These methods provide novel regio- and enantioselective transformations of electron-rich aromatic compounds.

The representative publications include J. Am. Chem. Soc.(4) and Angew.Chem.Int.Ed.(4). These 8 papers received  971 citations by others in total with 246 as the highest and 121.4 on average. Six ligands with intellectual property have been licensed to international chemical vender companies such as Strem Chemicals, J&K and Daicel Chiral Technologies and used worldwidely. This project trained 10 PhDs and 1 postdoc, with 5 awarded “Excellent Doctoral Dissertation of CAS”, 3 awarded “the Special Prize of President Scholarship”, 2 supported by “Thousand Youth Talents Plan Project”, 2 supported by “Hundred Talent Program of CAS”, and 8 promoted as associate/full professors. The first contributor delivered over 70 plenary or invited lectures, and received RSC Merck Award (2015), the 14th China Youth Science and Technology Award, Ho Leung Ho Lee Foundation Prize for Scientific and Technological Innovation (2016), and many other awards. He was invited to publish a personal account in Acc. Chem. Res., and edit a book entitled
Asymmetric Dearomatization Reactions. These results are of significant importance in the field of asymmetric synthesis and medicinal chemistry, significantly advance the selective transformations of aromatic compounds, and greatly promote the development of organic chemistry.

Destruction of North China Craton

This project belongs to the research realm of Earth Sciences.

    Cratons are the ancient cores of continents, characterized by the lack of obvious volcanic activity and violent earthquakes, and thus are traditionally thought to be tectonically stable over long periods of geological time. However, large-scale volcanic activities and great earthquakes have occurred in the North China Craton (NCC) since the Mesozoic, marking the loss of craton stability. The question why craton could lose its intrinsic stability has been a conundrum of nearly a century.

    This group started to study the destruction of the NCC from 2000 and has made a series of important contributions to the timing, scale and mechanism of the NCC destruction by conducting interdisciplinary research, including, 1) proposed the new concept of “craton destruction”, cognized that lithospheric thinning and large-scale magmatic-tectonic activities are the superficial phenomena, of which the essence is the loss of the tectonic stability of the craton, and provided well-accepted evidences demonstrating that the changes in the compositions and properties of the lithosphere were the key factors leading to craton destruction; 2) determined the temporal-spatial extent of the NCC destruction. The destruction mainly took place in the eastern NCC in the Mesozoic with a peak age of ca. 125 Ma, while the western NCC generally has retained its overall stability; 3) systematically expounded and proved the mechanism of the NCC destruction, found that Pacific subduction in the early Cretaceous is the main dynamic factor that triggered the NCC destruction. The dehydration of the stagnant Pacific slab in the mantle transition zone beneath the NCC caused unsteady mantle flows and decompression melting of mantle materials, eventually leading to the NCC destruction.

Eight representative papers have been cited 1200 times by other researchers. Two of these representative papers were among the ISI top 1% highly cited papers and all the five achievers are ranked in the list of the global highly cited researchers in geosciences. This group has edited two special issues in the journals of Lithos and Gondwana Research, respectively. The first achiever was selected as AGU-Fellow in 2011, who is the first geoscientist that received this honor in recent years in Mainland China.

    This group organized the International Conference on Craton Formation and Destruction (Beijing) in 2011, which attracted many famous scientists, including academicians from National Academy of Sciences of UK, Australia, Norway and USA etc. The National Science Foundation of China has reported four major achievements in the field of continental dynamics, among them the NCC destruction was the top one. The destruction of the NCC is the only research frontier dominated by Chinese scientists and was one of the Top 10 in Earth sciences in both 2014 and 2015 Research Frontiers jointly issued by the Thomson Reuters and Chinese Academy of Science. This project has been a successful example of studying the global continental evolution based on a regional case, which makes the regional issue of the NCC destruction not only become a hotspot in global scientific research, but also lead the direction of study on continental evolution. Such a success has significantly enhanced the international influence of solid Earth science research in China.

Late Cenozoic tectonic deformation of the Tibetan Plateau and its northeastern margin

Founded by the NSFC and 973 project, our group studied the late Cenozoic deformation processes of the Tibetan Plateau and its surrounding area. For more than 20 years we carried out two following interrelated topics, first, we utilized the global positioning system (GPS) observations to reveal the deformation pattern, velocity field and strain distribution of the Tibetan Plateau, and then to better understand the present deformation processes. Second, we targeted the youngest growing NE Tibetan Plateau to study the late Cenozoic formation processes of the Tibetan Plateau.
Three significant scientific findings can be summarized as follows, (1) Our analysis of GPS measurements indicates that 90% of the strain between Indian and Eurasian plates were absorbed by the deformation in and around the Tibetan Plateau. We also determined the present-day deformation pattern and velocity distribution across different tectonic units of the Tibetan Plateau. The interior Tibetan Plateau is characterized by expansion and shear strain, however, the plateau margins are dominated by compression strain. The "eastward extrusion" is actually eastward crust material flow and clockwise rotation from the internal plateau. (2) We determined that the formation of the northeastern Tibetan Plateau was featured by five stages, and the quasi-synchronous deformation during the late Cenozoic (10-12 Ma) is the most important geological event, which contributes to mountain uplift and basin destruction. Consequently, the northeastern Tibetan Plateau became the latest growing plateau margin, and ultimately its front has propagated across the Hexi Corridor basin into the Gobi-Alax block. (3) Our studies on the Cenozoic tectonics-climate-erosion processes revealed that the high terrains were created during the middle to late Miocene (10-12 Ma) around the Tibetan Plateau, and it provided consequent climatic change to drive the significant increasing rates of erosion and deposition. The rapid increase in sedimentation rate between 2-4 Ma was controlled by the global climate fluctuation during the glaciation-interglacial periods, and it contributed to the formation of the famous "molasse" deposits in the west China. This study significantly promotes the pioneer topics of interaction between the tectonics and climatic variation.
41 peer-reviewed international SCI papers were published, of which 21 papers are written by the group first author (corresponding author). Among these papers, highest citation for one manuscript is 564. Our eight representative papers were totally cited 1210 times by other authors. Two papers were published in journals Nature and Geology, and the citations are 898 with ranking No. 466 and No. 218 in ESI (Essential Science Indicators) database during 2001-2011, respectively. An invited review paper in Nature Geoscience in 2013 highlighted the representative paper 1 as one of the important progresses by the Department of Geology of Natural Science Foundation of China. The group was once rewarded as first prize by China Earthquake Administration. During the project, Peizhen Zhang was nominated as the academician of the Chinese Academy of Sciences, and the National Distinguished Young Scientist. Huiping Zhang was appointed as the National Outstanding Young Scientist. Peizhen Zhang was in a rank of 952 over 3402 global geoscientists during 2006-2016.

Studies on the Mesozoic granites and crustal evolution in the Cathaysia block

Along with the international research progress on granites and regional characteristic of South China, the research of granites in South China has been focused on tectonic setting, magmatism, granite and crustal evolution, granite mineralization. Cathaysia Block, located in the southeast and occupies two thirds of South China, is dominated by Mesozoic granite and volcanics.

A prominent characteristic of the granites in Cathaysia Block is their episodic occurrences, where Mesozoic granites are dominant relevant to the contemporary large-scale mineralization. Researches on Mesozoic granite in Cathaysia Block have been focused on three key scientific questions: (1) What is the geodynamic drive for the generation of granitic magmas and how magmas aquired emplacement space? (2) What’s the “heat source” and “material source” for granitic magmas? (3) How to identify metallogenic granite bodies from barren granite units? Our research group conducted a long-term research on these questions with supports from NSFC. Based on detailed field work, a comprehensive study that combined mineralogical, petrological and structural geological investigations was performed on more than 50 granite bodies, over 10 volcanic/sedimentary basins and Precambrian metamorphic basement in the Cathaysia Block. The main scientific discoveries are as follows:

(1) A subduction-extension model for the petrogenesis of Mesozoic granites in the Cathaysia Block has been established. This model elucidated the transformation of Tethys-Pacific tectonic domains and further revealed the extensional tectonic setting of the Cathaysia Block during the late Mesozoic and solved the key issue of geodynamics and “emplacement space” for granites and their mineralizations.

(2) Our work answered the question of the “heat source” for the formation of granitic magma, and revealed the relationship between the crust-mantle interaction, magma mixing and the “material source” for granitic magma. The composition, evolution history and Phanerozoic multi-phase reworking process of the Cathaysia Precambrian crust is revealed, leading to a discovery of a Palaeoproterozoic orogeny during Columbia polymerization in Wuyi terrane, and better constraints of the location of Cathaysia Block within Rodinia supercontinent.

(3) The geochemical features of tin and rare metal bearing granites in the Nanling region have been systematically studied.

Contamination profiles and physico-chemical control principles of persistent organic pollutants (POPs)

Persistent Organic Pollutants (POPs) are environmentally persistent, toxic, bioaccumulative, and capable of long-range transport. Stockholm Convention demands POPs control, reduction and elimination. POPs occurrence in environmental media and degradation mechanism are urgent problems to be solved. Funded by the National Natural Science Foundation of China and National Basic Research Program of China, the project investigated the environmental contamination profiles of POPs, and explored mechanisms of the catalytic degradation and adsorptive removal of POPs. Key findings include:

(1) Identification of POPs contamination profiles in typical environment. This project found several POPs environmental contamination features, including a comprehensive contamination profile of chlorinated legacy POPs in Tonghui River, Beijing, the particle size-dependent concentration distribution of brominated POPs in indoor dust and its crucial influence on human exposure assessment, emission and contamination of perfluorinated compounds (PFCs)  in chrome plating industry in China, and first discovered a China-specific PFOS alternative with POPs-like properties overlooked for over 30 years. Related publications have been cited by researchers from over 40 countries and used to draft China’s National Action Plan to implement the Stockholm Convention.

(2) Development of the catalytic destruction principles for POPs removal. The polychlorinated biphenyls (PCBs) dechlorination on the novel palladium-modified metal foam electrode was found to follow the first-order kinetics. The active hydrogen atom spillover mechanism of Pt electrodes was proposed and verified. The sequential defluorination mechanism in the electro-chemical oxidation of PFCs on the self-developed Ti/SnO2-Sb-Bi anode was elucidated. The photocatalytic mechanism of PCP by bismuth oxyhalides material was also proposed.

(3) Elucidation of adsorption behavior and mechanisms of PFCs removal. Powdered activated carbon and acrylic acid-based anion-exchange resins are found to be suitable for their removal with high adsorption capacity. The electrostatic attraction is found to be the main force, and the weak oleophilicity of hydro-oleophobicity of perfluorocarbon chain in adsorption process is verified. It is first reported that the superhigh adsorption capacity for PFOS and PFOA on porous adsorbents is mainly attributed to the accumulation of PFOS and PFOA in porous structure and the formation of micelles.

Nonlinear Mechanism of Runoff Generation & Transformation in Basin

This project belongs to the category of “Hydrogeography”. Runoff generation and transformation at basin scale is highly nonlinear, and understanding its law is very important for flood control and water security. Traditional methods are mostly based on the linear system theory resulting in large errors in runoff calculation. The nonlinear issue has been considered a bottleneck in developing hydrological sciences. Based on analyses of enormous hydrological datasets worldwide, the group has obtained internationally recognized achievements as follows:

      1. A power-law to reveal a nonlinear mechanism between runoff generation and soil wetness, rainfall intensity and land-cover was found by Prof. Xia for the first time in the world. Subsequently the nonlinear Time-Variant Gain Model (TVGM) was developed and validated using datasets from over sixty basins globally. Compared with linear models, TVGM increased the accuracy in runoff prediction by up to 63% with an average of 45%. This achievement was evaluated by the “Stockholm Water Prize” awardee, Prof. Biswas, as “Prof.Xia has been to develop a non-linear time-variant model. The work has significantly improved our understanding of water-land-environment-human-ecosystems interactions”; and appraised by Prof. Ababou as one of the representative achievements in “Non-linear and non-stationary unit hydrograph methods”. Prof. Savenije, President of International Association of Hydrological Sciences (IAHS), evaluated the achievement as “promoting the hydrological science basis for sustainable water utilization by developing a nonlinear time-variant system approach”.

      2. The group found the ratio of soil evaporation to total evapotranspiration as a nonlinear function of Leaf Area Index (LAI) and surface soil moisture. This work revealed the nonlinear mechanism for water and energy transformation at the interface of water and “Soil–Plant-Atmosphere- Continuum”(SPAC). The achievement has been widely cited and applied to highly-efficient use of agricultural water in North China, which was evaluated by Academician Zhenshen Li, the winner of State Supreme Science and Technology Award, as “achieved significant benefits by saving water of 100mm and obtaining crop yields of over 1000kg during two seasons”.

      3. The group developed a new Distributed Time-Variant Gain Model (DTVGM), through coupling spatially-distributed properties and multiple hydro-physical processes. A new approach to quantify modelling uncertainties was also developed. The DTVGM model and its application was cited by Prof.Gupta as “can be used to anticipate changes in catchment behavior and to evaluate consequences of natural and/or human-induced changes to the system”. It has been successfully applied to eight large basins in China and has brought prominent social and economic benefits.

      The eight representative papers have been externally (non-self) cited by 725 times, where the external SCI citations reached 577 times and the most cited paper has 151 external citations. Owing to the outstanding contribution to hydrological sciences, Prof. Jun Xia was awarded the 2014 INTERNATIONAL HYDROLOGY PRIZE-The Volker Medal for his “outstanding contributions to the sciences of Hydrology and application of his research and hydrological expertise to the benefit of society. It is awarded by IAHS with the support of World Meteorology Organization (WMO) and United Nations Educational, Scientific and Cultural Organization(UNESCO)”.

Molecular Mechanisms Underlying Locust Phase Change

This project was considered as a cornerstone in deciphering molecular mechanisms of phase change in Locusta migratoria through using integrative methods. This project published around 20 peer-reviewed papers and 8 masterpieces have been cited by other scholars for 410 times. The major achievements are summarized as follows:

First, Characterizing the gene expression profiles involved in phase change in L. migratoria. This project firstly carried out the genomic studies based on EST sequences. They identified 532 differentially expressed genes between solitarious and gregarious phase. Several genes of them were verified to be candidate regulators for locust phase change, for example, peptidase, JH binding proteins, oxygen-binding activities and those related to development. They also have established the database LocustDB of locust genetic information, which have extensively used by international scientists. The results were published in PNAS (Publication 1), and cited 111 times. This paper has been regarded as a classic paper in the field of ecological genomics and opened a new window for understanding locust phase change.

Second, revealing molecular mechanisms underlying the regulation of locust phase change. Through using Oligo DNA microarray, they revealed an asymmetric characteristic of phase change in the migratory locust and demonstrated that olfactory pathway plays key regulatory roles in the initiation of locust phase change (PLoS Genetics, Publication 5). They further found that dopamine pathway is the key mechanisms involved in the maintenance of phase traits including body color and behavior (PNAS, Publication 2). Metabolomic analysis revealed 319 phase-related metabolites, of which carnitines have been demonstrated to be involved in locust behavioral phase change, indicating a complex regulatory network involved in locust phase change (PNAS, Publication 2). They also revealed that GNBPs play key roles in the prophylactic immunity of crowded locusts, indicating an avoiding anti-disease strategy of gregarious locusts (PLoS Pathogens, Publication 6). These findings were evaluated as the first attempt to decipher the roles in the pathway from initiation to maintenance of phase change.

Third, exploring epigenetic mechanisms underlying locust phase change. Through developing a novel method to identify miRNAs independent of locust genome sequence, they identified conserved and locust-specific miRNAs and found that piRNAs have differentially expressed profiles between two phases (Genome Biology, Publication 4, Cited by 100 times). Then, A k-mer scheme to identify piRNA sequences was further developed relying on the training sets from non-piRNA and piRNA sequences. Through using this method, 87,536 locust piRNAs were identified, many of which display differential expression patterns between two phases (Bioinformatics, Publication 7). These computational methods to identify miRNAs and piRNAs have extensively used especially in the studies of non-model species. Other findings about transgenerational effects associated locust phase change were summarized in the review articles (Annual review of Entomology, Publication 8).

Summary, the comprehensive investigation of the complex regulatory mechanisms of phase change by this project have been highly recognized by the community of locust researchers worldwide. These results not only promoted the fundamental research of locusts, but also influenced on Genomics, Ecology and even biopesticide development.

Structural and functional study of plant receptor kinases

The membrane localized receptor-like kinases (RLKs) in plants play an important role in diverse biological processes including development, growth,differentiation and immunity. The receptor BRI1 is a receptor the plant hormone,brassinosteroid. The project team have successively solved the crystal structures of brassinosteroid complexed with BRI1, and complexed with BRI1 and BAK1. These two structures not only reveal the molecular mechanism underlying BRI1 perception recognition of BR but also provide the evidence that BR-induced BRI1-BAK1 heterodimerization is important for BRI1 activation. AtCERK1 is another RLK and responsible for detection of chitin, the major cell wall component of fungi,to activate plant immune responses. The crystal structure of an AtCERK1-ECD complexed with a chitin pentamer reveals that their interaction is primarily mediated by a LysM and three chitin residues. Their biochemical data support the notion that chitin-induced AtCERK1 dimerization is critical for its activation.The RLK FLS2 recognizes the highly conserved N-terminal epitope of flagellin (flg22) and functions together with another receptor-like kinase BAK1 to trigger the plant immune response. The project team solved the crystal structure of the ectodomain of FLS2 and BAK1 complexed with flg22.These structural and biochemical data reveal the molecular mechanisms underlying FLS2-BAK1 complex recognition of flg22 and provide insight into the immune receptor complex activation.these FLS2-flg22-BAK1 and BRI1-BL-BAK1/SERK1 complexes structural studies also suggest the SERK family of proteins may have evolved to allow a high degree of signaling diversity by functioning as co-receptors with different RKs. The direct interaction between the tomato protein kinase Pto and the Pseudomonas syringae effector protein AvrPto is known to trigger disease resistance and programmed cell death through disease resistance protein Prf. The project team solved two complex crystal structures of AvrPto–Pto and AvrPtoB–Pto. Their structural and biochemical analyses demonstrated that AvrPto/AvrPtoB is an inhibitor of Pto kinase in vitro and that functional mimicry of host proteins is an important mechanism used by microbial pathogens to modulate host cellular functions. Otherways The project team also show that AvrPto binds receptor kinases, including Arabidopsis FLS2 and EFR and tomato LeFLS2, to block plant immune responses in the plant cell. BAK1 is a conserved member of the SERK family of LRR-RLKs and was identified as co-receptors with different RKs. Their crystal structure of an AvrPtoB-BAK1 complex reveals the mechanism of AvrPtoB-mediated suppression of PTI.Together, these structural studies of plant RLKs formulate a general mechanism for their activation, which can guide our understanding of other RLKs.

Regulation and physiological mechanism in enhancing the remobilization of assimilates to grain and grain-filling in rice and wheat

Monocarpic plants such as rice and wheat need to initiate the whole plant senescence before their pre-stored assimilates can be remobilized for the grain filling. However, plant senescence and photosynthesis is a pair of trade-off processes. The coordination of plant senescence, photosynthesis and remobilization of assimilates is a long-term unsolved problem in cereals, and its regulation mechanism is not understood. This project addresses the two scientific issues: how to coordinate the relationships among plant senescence, photosynthesis and remobilization of assimilates and what the physiological mechanism is in enhancing the remobilization of assimilates to grain and grain-filling by a field practice. The main findings are:

1. Post-anthesis moderate soil-drying can regulate the relationship of plant senescence, photosynthesis, and remobilization of assimilates, and accelerate grain-filing. Post-anthesis moderate soil-drying means that plant can rehydrate overnight and will not severely inhibit leaf photosynthesis at day time. Importantly, it can timely and appropriately initiate the process of plant senescence, trigger assimilate remobilization from vegetative tissues to grain, and accelerate grain-filling, especially improve the fill of late-flowering inferior caryopses, leading to increases in grain yield, harvest index, and water use efficiency. The moderate soil-drying therefore provides a new way to coordinate the relationship among plant senescence, photosynthesis, and remobilization of assimilates during grain-filling and to achieve the dual goal of increasing grain yield and saving water in cereals.

2. Abscisic acid (ABA) and its interaction with ethylene and gibberellins (GAs) regulate assimilate remobilization and grain-filling. During the active grain-filling period, the fill of grain requires a higher level of endogenous ABA and higher ratios of ABA to ethylene and to GAs. Post-anthesis moderate soil-drying enhances the remobilization of assimilates to grain and grain-filling through increases in ABA levels and the ratios of ABA to ethylene and/or to GAs, which reveals the mechanism in which plant hormones regulate assimilate remobilization and grain-filling, and provides a physiological regulation to improve grain-filling in cereals.

3. A modest increase in ABA level in plants can enhance activities of the key enzymes involved in carbon metabolism, and thereby increases assimilate loading and unloading capacity. An elevated ABA level though moderate soil-drying or applying ABA with a low concentration can increase activities of the key enzymes in starch or fructan degradation and sucrose synthesis in vegetative tissues, leading to the enhancement in assimilate loading ability, and enhance activities of the key enzymes in sucrose-to-starch conversion in the sink organ, and consequently, increase assimilate unloading ability and starch synthesis in grain, which reveals the mechanism in which ABA regulates assimilate remobilization and grain-filling.

This project has yielded 37 SCI papers. Eight representative papers have been cited 666 times (excluding the citations of authors) in SCI database, and 905 times in Web of Science, and have received positive evaluations from scholars worldwide. Principal investigators of the project have been invited to make 14 presentations in international conferences. This project obtains three national invention patents and won the First-class Prize of Natural Science Award from the Ministry of Education in 2015.

Mechanism and pathological modulation of intracellular Ca2+ signals

Calcium is a prototypical and universal intracellular messenger, regulating most biological processes, from fertilization to cell cycle, from gene expression to protein modification and from muscle contraction to neural plasticity. Abnormal calcium dynamics and handling underlies most diseases. The most important question of calcium signaling is why a simple ion has so many important functions. As a continued effort in answering this key question, this project has been focused on the spatiotemporal patterning, regulatory mechanisms and pathological remodeling of intracellular calcium signals.

    We discovered highly localized microdomains of intracellular calcium, dubbed “calcium flickers” from the IP3 receptors in fibroblasts and “calcium nanosparks” from the ryanodine receptors (RyR) in cardiomyocytes, which are fundamental units of calcium signals controlling cell migration and cardiomyocyte contraction, respectively.

    We found that the calcium signaling efficiency for L-type calcium channels (LCCs) to trigger RyR calcium sparks is regulated directly by the b-adrenergic PKA signaling pathway, and by the miR-24-junctophilin-2 (JP2) gene regulation system. The expression of JP2 controls the nanoscopic junctions between the LCC-residing T-tubules (TT) and the RyR-residing sarcoplasmic reticulum (SR), and thus determines the efficiency of LCC-RyR signaling.

    We found that calcium signaling efficiency is decreased in failing heart cells due to disrupted TT-SR junctions. While up-regulation of miR-24 in heart failure decreased JP2 expression compromises the efficiency of spark generation, suppression of miR-24 protects the integrity of calcium signaling and effectively prevents the pathological development of heart failure.

    These findings not only revealed fundamental mechanisms and molecular regulations of intracellular calcium signaling, but also have important medical implications.

Functional glia-neuron coupling and ischemic neuroprotection

Stroke is the leading cause for mortality and diasblilty in China and around the world.Past research and neurotherapeutic clinical trials have targeted the molecular mechanisms of neuronal cell death during stroke, but this approach has uniformly failed and the underlying mechanism remains unclear. Recent researches suggest that brain function and dysfunction are manifested at the level of cell–cell signaling between neuronal, glial and vascular(neurovascular unit) elements.  Astrocytes play an active role in the pathoglical process of stroke and are the promising novel targes for stroke treatment. In this project, we extensively studied the signaling and functional coupling between neurons and astrocytes during normal and ischemic conditions supported by several national grants. The main findings are listed as the following:
1. It is found that glial cells regulate nerve activity and cell migration via releasing ATP by lysosomes and promoting Ca2 + diffusion wave. We provides the first in vivo evidence showing that the impairment of working memory by marijuana and cannabinoids is due to the activation of astroglial CB1R and is associated with astroglia-dependent hippocampal LTD in vivo and reveal novel mechanistic views of the role of astrocytes in learning and memory processes and of the memory-disruptive effects of marijuana intoxication..
2. We found that ischemia induced gliosis and glia scar formation determine the micro environment for neuronal damage and repair. Regulation of the cell cycle can reduce neuronal apoptosis and glial scar formation. Suppressing the cell cycle by specific inhibitors or dominant negative strategies may constitute potential therapeutic methods in neurological disorders including ischemic stroke.
3. We revealed the gap junctional coupling properties between astrocytes under normal and ischemic conditions. Astroglial GJC plays a significant role in MCAO-induced remote hippocampal damage and cognitive impairment. Our results suggest that manipulating GJC could be a new target in protecting stroke patients
  The project have published 125 papers in SCI. The 8 representative papers were published in Cell, Nature cell biology, Ann Neurol, Prog Neurobiology, Stroke and other top international journals, with a total impact factor of 99.215, which were cited 523 times, and one of them was cited 217 times. Key findings are highlighted and reviewed in Nature Rev Neurosci, Nature Neurosci and etc. And they were cited multiple times in Nature Reviews Molecular Cell Biology, Lancet, JAMA, Nature Medicine and other top journals (IF> 20 citations, 15; IF > 10 papers cited 38 times). The editor of "Prog Neurobiology" invited Professor Wang Wei writing a review on neural cell cycle dysregulation and central nervous system diseases which was published as a cover article. Part of the research results have been written in the teaching material for long term medical students. Our results were reported by over 150 international media including BBC, Nature

Molecular Interaction Mechanisms on HIV and Host Native Defensive Factors

There are series of natural host defense factors in human bodies, such as APOBEC3 family (A3) and SAMHD1, which have been discovered and identified during the process of AIDS research. Although its genetic organization is simple, encoding only three structure proteins and seven non-structure proteins, HIV-1/2 could break through the host immune defense system and has become one of the severe infectious diseases threatening human health. Hence, the researches on the interaction mechanism of viruses and the hosts have been the international concern for several decades. Our project has been focusing on the molecular interaction mechanism of HIV and host native immune system for the last two decades, and we have published 239 academic papers on SCI journals with the total citation being 7898. The following are the main original achievements:

1. The revelation of the molecular mechanism on HIV-1 Vif inducing the degradation of A3 proteins through host E3 ubiquitin ligase. The research finding proves that HIV-1 Vif degrades A3 through ubiquitin-proteasome by utilizing the host proteins, which reveals the replication mechanism of HIV virus by escaping from the host defense factors from a brand-new perspective. The discovery was published on Science, with SCI paper cited for 666 times by other people and recommended by the Faculty of 1000 as “Recommended”. The subsequent researches prove this mechanism is of universality and communality in the field of interaction of viruses and hosts.

2. The revelation of the regulatory function of host transcription factor CBFβ on Vif-induced formation of E3 complex, which has been puzzling virologists for decades. The Chief Editor of Nat Rev Microbiol has reviewed this paper as “the research finding is of significant contribution to the HIV research field”. The study was published on Nature, and has been selected by the Faculty of 1000. The research furthers the study of Vif function precision mechanism, and makes the resolution of crystal structure of Vif complex possible, which solves the long-lasting problem of Vif protein complex crystal.

3. The discovery and naming of Vpx of HIV, as well as the essentialness of Vpx in virus replication in macrophage. The research was published on Nature, J Virol., etc. The pioneering researches on the function of Vpx were selected as one of the top-10 researches in the field of Life Sciences and Medicine by Thomson Reuters Corporation in 2013. In 2013, we resolved the crystal structure of SAMHD1, and proved that the tetramer formation is essential for all the known activities of SAMHD1 (Nat Commun.)
we discovered SAMHD1 as a potent suppressor against endogenous retroelements, which is associated with innate immune regulation (Cell Rep.)and the research paper was published in the “Select” Column of Cell.

4. The discovery of major HIV strains circulating in southern China, CRF01_AE and CRF08_BC, with the latter the major HIV strain in China until now. The research findings have been published on Lancet and J Virol.. We set up the first AIDS patient matrix based on injective drug users, and monitored the circulation status and mutagenesis of HIV in China, both of which provide critical theoretical basis for the development of anti-HIV vaccine and drugs.

The overall impact factor of the 8 representative papers is 123.439, and the non-self SCI citation of these papers is 1313, among which 74 citations are from world-top journals like Nature, Cell, Science, Lancet, JAMA, and their sub-journals.

Theory and Methods of High-Efficiency and High-Maneuverability Control for Biomimetic Robotic Fish

This project belongs to the discipline of “Robotic Control”.

This project focuses on how to apply the fish swimming propulsive modes to the design and control of robotic fish, and propose theory and methods of modeling and control for biomimetic robotic fish, which provide key theory and methods for the development of novel high-efficient, low-noise, high-maneuverable aquatic propulsion systems. The main scientific contributions are listed as follows:

1. The fish swimming oriented “base wave” concept is first proposed and applied to systematically describe the fish body’s cyclic shape changing motion. A novel fish body wave model and propulsive control method are creatively built, which achieve stable swimming propulsion for a class of multi-joint biomimetic robotic fish. The proposed fish swimming theories are well verified by self-developed robotic fish.

2. The “C-curve” based dynamic trajectory tracking control is first proposed to achieve highly maneuverable turns. An intelligent control framework is established for complex, 3D maneuvers. Typical maneuvers such as submerging, depth maintaining, fast start, snap turn and turning are demonstrated. In particular, the flipping motion and the jumping-out-of-water motion are first implemented on the physical robotic fish series.

3. An optimal index is proposed for the multi-linkage biomimetic robotic fish, and the thrust description is derived under the stable swimming condition. An optimization method based on a delayed neural network is proposed, and its global exponential stability condition is proved. Therefore, the goal of improving swimming performance of the robotic fish through the optimal mechanical system design is achieved.

4. The cooperative control framework and mechanisms for multiple biomimetic robotic fishes based on local information sensing and limited communication are established. Within this framework, a neural network based distributed robust adaptive control method is proposed, and its necessary and sufficient condition for system consensus are proved. Cooperative tasks like formation, transportation, and monitoring are demonstrated.

Theory and Methods of Coded Mixing Imaging and Computational Reconstruction

High-resolution (HR) Imaging has many significant applications in defense security, remote sensing, and medical imaging, etc. In conventional imaging techniques, the imaging resolution is mainly determined by the resolution of the detectors and the bandwidth of the detected signals. However, due to the fact that it is rather difficult to produce the HR detectors and impossible to use broadband signals for far-field detection, the HR imaging and detecting is a very challenging task puzzled academy a long time. As an important research direction, it is promising to reconstruct HR images from its LR observations exploiting the prior knowledge of natural images. One of the fundamental problems, which puzzles academy a long time, is how to design robust imaging systems, reveal the mechanisms of effective reconstructions, and build HR image reconstruction models.
    This project was sponsored by National Science Foundation of China (NSFC) and 863 Project. After more than 10 years’ research, this project clarified the mechanisms of HR imaging using LR detectors, revealed the computing properties adaptive to spatial-temporal structures, discovered the principles adaptive to perceptual differences, and proposed computational reconstruction models adaptive to multi-subspaces sparse structures. The major scientific discoveries include:
    1. Coded Mixing Imaging – We have clarified the mechanisms of HR imaging using LR detectors and revealed the principles of coded mixing imaging and HR image reconstruction. The proposed methods enhance the resolution limits of conventional imaging and achieve HR images without the use of HR detectors.
    2. Structured Image Representation – We have clarified the compact representations for distinctive image structures and textures and revealed the mechanism of using local subspaces for compact representation. We have also proposed structured representation methods based on sparse subspaces selection and discovered the computing relationships for sparse subspaces learning by exploiting self-similarities. Finally, we have built new compact image representation frameworks using subspaces selection.
    3. Comutational Image Reconstruction – We have clarified the effects of compact image representations on HR image reconstruction and revealed the law of recovering the HR image from LR images. We have also discovered the mechanisms of structured sparsity prior learning and representation and proposed model driven image reconstruction methods, achieving robust and accurate HR image reconstructions.
Our works have been highly praised by international peers, including Prof. T. Huang and Prof. S. Osher. The local subspaces learning method adapted to local image structures is commented as one of effective and optimal dictionary learning methods. Structured sparse prior learning is commented as one of the most effective structured sparse coding approaches. The model driven HR image reconstruction method is commented as one of the most impressive image reconstruction methods. Based on the above discoveries, we have developed robust spectral imaging systems for nano-satellites and earth observation applications.

Analysis and Control of Networked Dynamic Systems

With the increasing expansion of industrial manufacturing systems, massive amounts of physical devices are connected into dynamically evolutionary networks by various means of communication. Through real-time interactions, numerous individual nodes form a networked dynamic system. New theories and novel approaches need to be developed accordingly since the traditional control theory and methods cannot fit in with the increasing complexity of networked dynamic systems.
  This project was supported by one National Natural Science Fund for Distinguished Young Scholar and several other funds from National Natural Science Foundations of China, and has been accomplished by more than 10-year team collaboration formed by the natural relationship of supervisor and students. In the aspects of node dynamics, dynamic performance, structural attribute, and network effects, several fundamental problems in the coordination control of networked dynamic systems have been deeply investigated and some major breakthroughs have been achieved. The outcomes of the project provide fundamental theories and original techniques for further development of the coordination control of networked dynamic systems.
1) Complex Node Dynamics and Dynamic Performances of Networked Dynamic Systems: Two classes of practical system structures have been proposed. Distributed control protocols have been designed to solve the corresponding coordination control problems and their convergences have been rigorously proved. Furthermore, the finite-time consensus problems have been solved, which reveal the relationship between convergence times and algebraic connectivity of communication topologies.
2) Structural Attribute of Networked Dynamic Systems: A series of new concepts and tools including the reachable state set of switching sequence, the concatenation of switching sequences have been proposed. The quantitative relationship has been established between the reachable state set of the concatenation of two switching sequences and those of the two switching sequences. Then, a switching sequence that generates the controllable state space of the whole system is constructed. By using the concept of column space, cyclic invariant subspace and the geometric space method, some controllability criteria in more general forms have been established, which show that the link weights of communication topologies have an important effect on the controllability of networked dynamic systems.
3) Network Effects in Networked Dynamic Systems: A class of local control protocols for networked dynamic systems have been designed in the presence of time-varying network effects. For discrete-time networked dynamic systems, a criterion for the consensus has been established by the state augmentation method. For continuous-time networked dynamic systems, several feasible LMI conditions for the consensus have been established by introducing a tree-type transformation.
4) Sampled-data Control of Networked Dynamic Systems: A protocol-designing scheme for sampled-data control of networked dynamic systems has been presented. It has been proved that the designed protocol can solve the consensus problem in the case of bounded time-varying delays and time-varying directed networks, which reveals the intrinsic connection between the asynchronous consensus control of networked dynamic systems and the network-induced delays.

Fundamental research on the synthesis and applications of high-quality graphene materials

Graphene has attracted increasing interest since 2004 because of its unique structure, many fascinating properties and promising applications. The properties of graphene materials strongly depend on their structure such as the number of layers, defects, grain size, and functional groups. Therefore, the synthesis of high-quality graphene materials with controlled structures is essentially important not only for fundamental studies but also for technological applications. Since 2007, we have systematically studied the synthesis of high-quality graphene materials by chemical vapor deposition (CVD) and chemical exfoliation, and explored their potential applications in energy storage, composites, optoelectronics, etc.

  Until the end of 2013, more than 40 peer-reviewed papers have been published in Nat Mater, Nat Commun, PNAS, Adv Mater, JACS, etc. and 16 patents have been granted. Drs. Wencai Ren and Hui-Ming Cheng (the first two achievers) have been invited to write a “News and Views” editorial for Nature in 2013 and a Commentary article entitled The Global Growth of Graphene for Nat Nanotechnol in 2014. The 8 representative papers shown in the Part III (Publications) have been cited 4,464 times by others (Web of Science) in Science, Nature, Nat Mater, Nat Nanotechnol, Adv Mater, Chem Soc Rev, Prog Mater Sci, etc. The related main discoveries are summarized as follows:

(1) We have invented a template-directed CVD method for the synthesis of a novel graphene foam macrostructure with a three-dimensional (3D) interconnected network (Nat Mater, 2011, 1185 citations), and demonstrated its use in high-performance elastic conductors (Nat Mater, 2011, 1185 citations) and flexible lightweight electromagnetic interference shielding materials (Adv Mater, 2013, 262 citations). The Nature Mater paper has been highlighted by Nature, Nature China, and NPG Asia Materials, and this method has been widely used by many research groups.

(2) We have developed an ambient-pressure CVD method with Pt as the substrate to achieve the growth of millimetre-size hexagonal single-crystal graphene domains (Nature Commun, 2012, 355 citations), and found the edge-dependent growth kinetics of graphene (PNAS, 2013, 42 citations). Moreover, we have developed a universal nondestructive electrochemical H2 bubbling method to transfer CVD-grown graphene to arbitrary substrates (Nature Commun, 2012, 355 citations; invention patents granted by China, US, Europe, and Japan), which allows the repeated use of the metal growth substrates.

(3) We have designed and fabricated a series of graphene sheet/metal oxide nanoparticle composite electrode materials to greatly improve the performance of lithium ion batteries and supercapacitors, and elucidated the synergistic effect between the graphene sheets and metal oxides in the composites (ACS Nano, 2010, 1206 citations; Adv Funct Mater, 2010, 540 citations).

(4) We have developed a hydrogen arc discharge exfoliation and reduction method for the synthesis of graphene sheets with excellent electrical conductivity and good thermal stability (ACS Nano, 2009, 311 citations). Moreover, a simple but highly-efficient hydrohalic acid reducing method has been invented to reduce graphene oxide films into highly conductive graphene films without destroying their integrity and flexibility based on a nucleophilic substitution reaction (Carbon, 2010, 563 citations), which has been widely used by many groups.

Solar Materials and Photovoltaic Cells: Structure Design, Facile Fabrication and Solar Conversion

This project belongs to the interdisciplinary field of inorganic nonmetallic materials.

High performance materials forphotovoltaic conversionare key technology for solar cell design and construction. These materials are the basis for one of the most promising technological advances to utilize solar energy. It is a tremendous challenge to design the structure and optimize its property for materials to break through the scientific conundrum of wide-spectrum absorption and rapid separation of the charge carriers. In this project, systematic investigations of structure-performance relations and packing factor have been conducted to address these mutual restriction factors.

Based on innovative strategies, this project has designed and prepared high performance novel photovoltaic materials with wide-spectrum absorption, rapid separation of the charge carriers and high transparency correlated with high electronic conductivity. On this basis, a series of high performance photovoltaic materials were developed for photocatalysis and solar cell applications. A pilot-scale product line of CuInGaSe2 (CIGS) has been built in SICCAS. The technology of material synthesis and device fabrication has been transferred to a commercial company. The primary discoveries of this project are briefly summarized below:

1) New Concept for Design of Multifunctional Compounds. We have discovered a rule of Similar Atoms Gathering Together (SAGT) and proposed a new principle of dual structural functional units for designing multifunctional compounds. On the basis of this, a series of p-type transparent conductors were synthesized whose performance is much better than the compounds reported in the literature. We have also discovered a simple but universal model, i.e., that of crystal packing factor (PF), to evaluate the properties of photovoltaic materials especially for photocatalysis.

2) Novel Design for Wide-Spectrum Absorption and Rapid Separation of Charge Carriers. According to the model of packing factor, we have discovered a new composite structure, i.e. <n-type semiconductor I |Semimetal|n-type semiconductor II>, which enables promotion of wide-spectrum absorption of solar spectrum and rapid separation of charge carriers in photovoltaic conversion materials.

3) New Preparation Method for Complex System Using Reverse SAGT. Utilizing the reverse of SAGT, i.e., dissimilar atoms do not gather together, we have discovered that auto-aggregation of atoms of metastable materialsis beneficial for improving single phase products. This rule turned out to be a universal principle. This principle was used to prepare high efficient CIGS (Cu/In/Ga/Se) solar cells.

4) Novel Technology of CIGS Devices by Non-Vacuum Liquid Method. Focusing on low-cost and large-scale production of CIGS solar cells, we have discovered a novel technology, i.e., a non-vacuum liquid method, to prepare CIGS thin films and to fabricate solar cells; we have also proposed strategies to synthesize indium-free back electrode, boron-doped graphene with matching work function, and indium-free front ZnO:Al electrode. Accordingly, high performance CIGS solar cells have been fabricated to obtain an efficiency of 16.6% as confirmed by a third-party inspection. A pilot-scale product line of CIGS solar cells has been built in SICCAS. The technologyof the preparations of the materials and devices has been transferred to a commercial company.

The above discoveries have promoted the development of materials for photovoltaic conversion, and have been highly regarded by international fellow scientists. This project has published 118 SCI papers in the journals of Adv. Mater., J. Am. Chem. Soc., Energy Environ. Sci., and Adv. Funct. Mater.etc. Moreover, eight representative papers have been cited 1505 times with an average impact fact of 15.847, and six papers have been ESI highly cited. A single paper has the highest citation of 539 times. Thus far, 58 invention patents have been authorized.

Intrinsic versus extrinsic size effect on strengthening and toughening of metallic materials at micro/nano scales

This project belongs to the field of materials science.
Increasing simultaneously strength and ductility/toughness is an eternal theme and key point in metals. With the progress of technologies, both the internal microstructural features controlling the mechanical properties of metals and the external size of metals used in micro/nano-devices have been reduced to the micro/nano-scales, similar to dislocations and twins. The mechanical properties, usually regarded as relying only on the internal microstructures, are now strong external size dependent. In this project, we have discovered a number of coupling internal and external size effects on the deformation, which may provide new strategy for strengthening/toughening metals. The key findings are:
1. We discovered strong sample size effect on twinning behaviors in micro/nano-sized metallic single-crystals. The deformation mechanism is changed from twinning-dominated to dislocation slip-dominated at the size of about one micron-meter. Consequently the maximum flow stress touches the ideal strength, with substantial compressive plasticity remained. Prof. Kraft, the president of MRS of United States, commented in the column “News & Views” of Nature Materials that “Intuitively, one might imagine that there is no size effect for twinning of a small single crystal. However, Yu et al. show that the opposite is true”.
2. We proposed a multi-scale model to describe the coupling effect of multi-scale second phase particles on the ductility/fracture toughness of industrial alloys. Following this model, both the strength and the ductility/toughness of alloys can be simultaneously improved, in particular by controlling the intragranular nanoparticle-dislocation interactions to enhance the work hardening of ultrafine grained alloys. In the column “News & Views” of Nature Materials, Prof. Valiev, a member of The Academy of Europe, commented that “a more efficient nanostructuring route that simultaneously enhances the strength and ductility”.
3. We established a micromechanics model and revealed the coupling effect of internal modulation structure and external sample size on the strengthening and toughening of nanostructured multilayer film micropillars. A superhigh strength over the ideal strength of constituent layer as well as considerable compressive plasticity were found in the submicron crystalline Cu/amorphous CuZr micropillars with 10 nm layer thickness, which were commented as “can fundamentally alter the mechanical behavior, and have demonstrated the sought-after combination of high strength and improved tensile elongation that has eluded equiaxed nanocrystalline metals for over a decade” by an Acta Materialia Paper.
Our eight representative papers are all published in first-class journals such as Nature and Nature Materials, and received more than 425 citations by our peers in SCI journals. Of the eight papers, two are selected as ESI highly cited papers, and one is awarded as one of the “Most influential 100 papers in China”. Some of them are incorporated into 3 Springer and Cambridge University Press books. Over 30 invited talks are delivered in international conferences. Our major achievements are featured 2 times in Nature Materials, and also in the journals of Nanotoday, NPG Asia, and Nature China. Some of the achievements are awarded the “Top Ten achievements in Science and Technology of Chinese Universities in 2010”.

Function regulation, crystal growth and giant magnetostrain properties of advanced magnetoelastic materials

Magnetoelastic materials are a new class of strategic functional materials, including magnetostrictive alloys and magnetic shape memory alloys. Magnetoelastic materials play important roles in the defense and civilian high-tech fields. However, the development of high performance magnetoelastic materials are hindered by the traditional homogeneous magnetoelastic mechanism and non-faceted solidification theories. Since 2001, this project has systematically investigated new mechanisms of function regulation of magnetoelastic materials, new material design, and high-performance crystal growth. Important scientific discoveries are as follow:

1. Tetragonal nanoheterogeneities were observed in FeGa magnetostrictive alloys. New mechanism of nanoheterogeneous magnetostriction effect was proposed, which was completely different from the traditional homogeneous magnetostriction effect. Along with this mechanism, by doping slight amount (0.2at%) of rare earth element Tb to couple with the nanoheterogeneities, new FeGaTb giant magnetostrictive alloys were developed, the magnetostriction of which was five times larger than the maximum value previously reported in FeGa alloys.

2. Phenomenon of "coupling phase transition" was discovered between the first-order martensitic transformation and the second-order magnetic transition. The subsequent magnetic field-induced martensitic transformation and the accompanied multiple functionalities were all based on this scientific discovery. Idea of "isostructural alloying" was proposed and the coupling transition was realized over wide temperature window of 70-350K.

3. The effect of valence electronic concentration on the martensitic transformation temperatures of magnetic shape memory alloys was revealed. New systems of Mn2NiGa with high Curie temperature, Fe2MnGa with high saturation magnetization, and Ni2FeGa with high ductility were proposed. New system of Ni-rich NiMnGa high temperature shape memory alloys were proposed, the shape memory effect and thermal stability of which were the highest as already reported.

4. Phenomenon of multiple preferential orientations were observed during the faceted crystal growth of the above two kinds of magnetoelastic materials. The formation mechanisms of different orientations were revealed. An equation was proposed to describe controlling of the solid-liquid interface. Theories of faceted crystal growth were developed.

Based on the above scientific discoveries, series of high-performance magnetoelastic crystals were successful grown and have realized important applications in the development of acoustic vibration of oil-assisted mining system and deep-water transducer. It was evaluated that "enhancing recovery by 7.14%, which will become an important technical method to further improve waterflooding oil recovery for high water cut oil fields" and "has been successfully applied to China's deepest potential deep-water transducer development".

This project has published 152 SCI papers, including 5 in Acta Mater, 1 in Nature Commun, 1 in Adv Mater, 13 in Phys Rev B, and 60 in Appl Phys Lett. The listed 8 representative papers have been cited 757 times by Acta Mater, Nature Mater, Phys Rev Lett, Mater Sci Eng R and other SCI journals. The highest citation number was 175 for a single paper. Three papers were selected as the ESI highly-cited papers. This project was highly evaluated by famous scientists over the world, including Prof. E. Quandt from the German Science and Technology Academy, Prof. A. Lapdev from the Sweden Royal Science Academy, and five academicians of China. Our group contains one National Outstanding PhD, one Outstanding PhD of the China Academy of Sciences, one National Outstanding Young Scholars, one Changjiang Scholar of the Ministry of Education, one leading talent of the Central Organization Department. Part work of this project won the first prize of the Ministry of education of natural science.

Theories and methods for multiphase flow, mass transfer and energy transport, storage and conversion in solar photocatalytic hydrogen production

Hydrogen is the most promising and high-quality clean energy in 21st Century. Via solar photocatalytic hydrogen production, solar energy can be converted into and stored by hydrogen energy with high efficiency, low cost in a clean and large scale way. It provides ideal option for fossil fuel supply and the pollution problems of its combustion. As estimated by the US DOE, 5-10% conversion efficiency of solar to hydrogen ensures the technology industrialization. However, solar energy has low density and is dispersion and intermittence. A large increase in conversion efficiency of solar light is the core research goal, but also a world-class challenge and hot issue. The key scientific problems are the collection, transfer and conversion mechanism of non-steady solar radiation in the hydrogen production reaction system and the spatial-temporal multi-scale matching rule of energy and mass flow in continuous multiphase flow hydrogen production in chemical reaction under multi-physics coupled field. By studying the energy and mass flow and transportation, conversion and reaction and their inter-matching mechanism in the whole transportation and conversion process for solar to hydrogen energy from three levels of reaction system-interface-catalyst particles, the project put forward new theories and methods to improve the efficiency of solar hydrogen conversion, forming the designing theory for multiphase flow and continuous reaction instrument for photocatalytic hydrogen production under direct solar light. The main points of the project include:1) The mechanism of energy and mass flow, transport, storage and conversion in the solar photocatalytic hydrogen production system was revealed, and coupling of gradient distribution of catalyst particles and heterogeneous reaction flow was found to effectively promote the absorption, storage and conversion of solar light. It was found that bubble can strengthen the light absorption and promote hydrogen bubble nucleation. The correlation and coupling rules between radiation and the reaction flow were illustrated which solves the problem of low energy transport and conversion efficiency in photocatalytic system. The discovery was evaluated as “few”, “industrial” potential and “important for understanding and the initial applications in photocatalysis”; 2) The enhancement theory for energy and mass storage and transport at liquid-solid interface during solar photocatalytic hydrogen production is put forward. The effect that multi-scattering of photons at interface of the reaction liquid and the catalyst particles can enhance solar energy storage was found. The multi-point synergistic mechanism for energy transport and conversion at phase interface was clarified. New ideas were put forward to reduce the interface resistance for energy transfer and promote the selective conversion of reactants by controlling the interface microscale structure, solving the problem of low solar absorption, high resistance and low conversion at solid-liquid interface in hydrogen production process. It was evaluated as “only”, “provide an imperative for understanding…the microstructure of the…interface” and a “general strategy”; 3) The design theory of continuous flow photocatalytic hydrogen production system under direct solar light was established, realizing the enhancement in energy and mass absorption, transfer and conversion. It proposed a new concept of coexistence of two phases, successfully finding and preparing the twin homojunction catalyst and clarifying the enhancing mechanism of collection, absorption, migration and conversion of photons into transition energy of electrons within the particles by twin homojunction. It was found that 1D long-range ordered twin homojunction can greatly strengthen the photogenerated charge migration and separation. It also revealed the rules of continuous adjustment of the wide spectral response by changing the composition and thus the band structures of the catalysts. The ever existed problem of the low matching and exchanging efficiency between photocatalyst and aqueous solution was solved by hydrothermal method. Pilot and large scale demonstration systems for direct and continuous multiphase flow solar photocatalytic hydrogen production were successfully developed, achieving 6.6% of energy conversion efficiency using non-noble metal catalyst, which is the highest value reported and commercially available. The pilot demonstration was featured in the Newsroom by the Society of Photo-Optical Instrumentation Engineers. It was evaluated as “typical”, “creative”, “resulted in a remarkable quantum yield”.
8 representative papers have been cited by 1113 times without self-citation, and 6 of them are ranked in ESI. The project was awarded the 1st class of Shaanxi Science Technology Prize in 2016 and is expected to promote the formation of new interdisciplinary branch of multiphase flow photocatalytic physicochemistry.

Fracture Mechanics of Advanced Functional Materials and Structures

The nonhomogeneity and multi-field coupling features of advanced functional materials (AFMs) have received immense attention from the mechanics community in last decades. The security evaluation of them is a prerequisite to the development of national defense and aerospace fields. Under the continuous support of NSFC, the team has been working on fracture mechanics of AFMs in nearly 20 years. Systematic theory was formed to build solid foundation for the design, analysis and evaluation of AFMs. The team’s work has distinct research features and promotes the development of fracture mechanics of AFMs. The primary discoveries are listed below.
Discovery 1: Established theoretical methods for the typical fracture problems of functionally graded materials (FGMs) with exponential-type properties. The integral singular features were found for crack problems of orthotropic FGMs. The coupling effects of the orthotropy and the nonhomogeneity on the crack-tip characteristic parameters were demonstrated. The impact fracture mechanics model was constructed for FGM coating-substrate structures and the transient response of the interface crack-tip fracture parameters was described accurately. These investigations were reviewed as “representative papers” in fracture field of FGMs.
Discovery 2: Constructed a theoretical model for the crack problems of FGMs with general material properties. A piecewise-exponential-function based method for approaching general nonhomogeneous properties was proposed. Then a piecewise-exponential model (PE model) was established for the crack problems of FGMs with general material properties. A key scientific problem elicited by the crossing-interface crack problem was solved. The constructed PE model overcomes the limitation of the traditional exponential-type model which usually does not match actual cases. Particularly, the doubt about the traditional exponential-type models in recent thirty years were clarified.
Discovery 3: Constructed the multi-field coupling theoretical method of fracture mechanics for functional magneto-electro-elastic (MEE) materials. The theoretical model for multi-field coupling fracture mechanics of MEE materials was established. The variation mechanism of field intensities due to the interaction of multiple cracks was clarified. The influence of the nonhomogeneity parameter on the crack-tip characteristic quantities was revealed. These works have built solid foundation for fracture evaluation of MEE materials. The concerned achievements were deemed to “took the lead in this field”.
The representative papers of this project have been cited 313 times by SCI. The representative papers 1 and 2 were reviewed as “representative papers on fracture and fatigue of FGM since 2000” by the review paper in Appl Mech Rev. The representative papers 1 and 5 won “most cited papers” from Int J Solids Struct and Eur J Mech A-Solids, respectively. The famous scientist, Prof. Erdogan who made important contributions to fracture mechanics, and Prof. Zhang from Universität Siegen, Prof. Kashtalyan from University of Aberdeen, Prof. Lee from Yonsei University, et al., have made positive comments on the results.

Sliding Behaviors and Mechanics Models of Van Der Waals Layered Media

The van der Waals (vdW) layered media constitute one big class of materials. Typical examples are graphite and multi-walled carbon nanotubes that are made of multilayers of graphene. The vdW media have strong intralayer chemical bonds and weak interlayer vdW forces, which give rise to many unique and extreme mechanical properties including high anisotropy and ultra-low interlayer shear resistance. Since year 2000, the team has led pioneering and in-depth theoretical and experimental studies on structural superlubricity and continuum mechanics models of vdW media, which include

(1) Structural superlubricity. The dream of achieving “zero” friction at solid interfaces is a long-pursued goal of human being. It was predicted in 1990 that incommensurate interfaces could host nearly zero friction, named as structural superlubrictiy, however, only at nanoscale, under ultrahigh vacuum condition, and at a low sliding speed. In 2012, this team reported the first observation of micrometer-scale superlubricity at ambient conditions and speeds up to 25m/s (Representative Paper (RP) [1]), which has been recognized as a break-through and big advance by leading experts in the field and has attracted enormous research interests. The experimental setup is related to another discovery by the team – self-retraction motion of graphite crystal (RP [2]), where vdW interaction was revealed as the driving force (RP [3]). Based on this unique phenomenon, this team designed novel experimental tools to study structural superlubricity and measure cohesive energy of the vdW media. This team also leads mechanism studies of the self-retraction motion.

(2) Continuum mechanics models: The team revealed that the novel elastic buckling behaviors of vdW layered media stem from its extremely high anisotropy in elastic constants, and developed continuum mechanics models that successfully explained several anomalous experimental observations reported in Science (1997, 1999) (RP [4]). The team discovered that graphite has the highest elastic anisotropy among all hexagonal crystals and single walled carbon nanotube bundles have higher elastic anisotropy (RP [5]). The team developed the first mechanical model for single walled carbon nanotubes, embodying all elastic constants, elastic anisotropy, and size effect (RP [6]), a multi-beam shear model to explain anomalous vibrational behaviors of graphene-multilayer beams (RP [7]), and a model for strength and toughness design of vdW layered media based on their microstructures and interlayer cross-links (RP [8]).

The successful pose of the abovementioned scientific questions and obtained conclusions significantly advance the progress of solid mechanics and relevant interdisciplinary fields. The team provides valuable scientific insights in achieving ultra-low friction and wear and practical design of high performance materials with micro- and nanostructures.

The eight representative publications have been SCI-cited for 592 times including Science, Nature and Review of Modern Physics (Appendix 7). Team members have been invited to give plenary keynote talks over 10 times (Appendix 7.1). The work has been positively commented by many prominent researchers including Nobel laureates A. K. Geim and K. S. Novoselov, Academy Member Ted B. Belytschko, Huajian Gao, Joost W. M. Frenken, Wei Yang, Jianbin Luo. It also helped to establish the first 973-project with particular focus on structural superlubricity.
