| 1 | Recent progresses in application of functionalized graphene sheets显示文摘Graphene,a rapidly rising star on the horizon of material science,has a unique two-dimensional nanostructure as well as exceptional mechanical and electronic properties.Despite its short history,graphene has exhibited great potential in various applications.In order to implement the potential applications,functionalization of graphene is necessary to obtain uniform dispersions for good processability.Two kinds are dominant for functionalization such as covalent and non-covalent methods.The former is based on the formation of covalent bonds,and the latter the interaction among molecules.In this review,we summarized briefly the recent progress of functionalized graphene sheets (FGs) in different fields,such as optoelectronic materials,sensors,energy storage materials,catalytic,reinforcing components and so on,and also prospected the development trend of FGs in the future. | Lü Peng,FENG YiYu,ZHANG XueQuan,LI Yu & FENG Wei School of Materials Science and Engineering,Tianjin University,Tianjin 300072,China | 2010 | Science China(Technological Sciences)2010，53，9： | 7 |
| 2 | Azobenzene/graphene hybrid for high-density solar thermal storage by optimizing molecular structure显示文摘A large capacity storing solar energy as latent heat in a close-cycle is essentially important for solar thermal fuels. This paper presents a solar thermal molecule model of a photo-isomerizable azobenzene(Azo) molecule covalently bound to graphene. The storage capacity of the Azo depending on isomerization enthalpy(ΔH) is calculated based on density functional theory. The result indicates that the ΔH of Azo molecules on the graphene can be tuned by electronic interaction, steric hindrance and molecular hydrogen bonds(H-bonds). Azo with the withdrawing group on the ortho-position of the free benzene shows a relatively high ΔH due to resonance effect. Moreover, the H-bonds on the trans-isomer largely increase ΔH because they stabilize the trans-isomer at a low energy. 2-hydroxy-4-carboxyl-2′,6′,-dimethylamino-Azo/graphene shows the maximum ΔH up to 1.871 e V(107.14 Wh kg^(-1)), which is 125.4% higher than Azo without functional groups. The Azo/graphene model can be used for developing high-density solar thermal storage materials by controlling molecular interaction. | LI Man FENG YiYu LIU EnZuo QIN ChengQun FENG Wei | 2016 | Science China(Technological Sciences)2016，59，9： | 6 |
| 3 | Progress on the hydraulic measures for grid slotting and fracking to enhance coal seam permeability显示文摘A method of hydraulic grid slotting and hydraulic fracturing was proposed to enhance the permeability of low permeability coal seam in China. Micro-structural development and strength characteristics of coal were analysed to set up the failure criterion of coal containing water and gas, which could describe the destruction rule of coal containing gas under the hydraulic measures more accurately. Based on the theory of transient flow and fluid grid, the numerical calculation model of turbulence formed by high pressure oscillating water jet was used. With the high speed photography test, dynamic evolution and pulsation characteristics of water jet water analysed which laid a foundation for mechanism analysis of rock damage under water jet. Wave equation of oscillating water jet slotting was established and the mechanism of coal damage by the impact stress wave under oscillation jet was revealed. These provide a new method to study the mechanism of porosity and crack damage under high pressure jet.Fracture criterion by jet slotting was established and mechanism of crack development controlled by crack zone between slots was found. The fractures were induced to extend along pre-set direction,instead of being controlled by original stress field. The model of gas migration through coal seams after the hydraulic measures for grid slotting and fracking was established. The key technology and equipment for grid slotting and fracking with high-pressure oscillating jet were developed and applied to coal mines in Chongqing and Henan in China. The results show that the gas permeability of coal seam is enhanced by three orders of magnitude, efficiency of roadway excavation and mining is improved by more than 57%and the cost of gas control is reduced by 50%. | Lu Yiyu Ge Zhaolong Yang Feng Xia Binwei Tang Jiren | 2017 | International Journal of Mining Science and Technology2017，27，5： | 4 |
| 4 | Segmental Translocation Contributed to the Origin of the Brassica S-locus显示文摘Self-incompatibility(SI),which has recurred during the evolution of plants,is one of the most important cross-pollination mating systems.Three S-loci have been reported in Brassicaceae,namely,Arabidopsis lyrata(Al),Brassica(Br),and Leavenworthia alabamica(La)S-loci.Here,through multi-genomic comparative analysis of 20 species,we revealed that the most ancient S-locus was formed prior to the divergence of Brassicaceae lineage I and II.Itwas retained and inherited by Arabidopsis,as the Al S-locus in Brassicaceae lineage I.Furthermore,we found that the Br S-locus,which has been widely used in the breeding of Brassica crops to generate hybrid seeds,was formed through segmental translocation(ST)in the hexaploid ancestor of Brassica in Brassicaceae lineage II.The Br S-locus was evolved through a ST from one of the triplicated ancestral S-locus paralogs in the Brassica hexaploidy ancestor,while the other two S-locus paralogs were lost.Together with the previous discovery that the La S-locus was formed through a secondary origin in Brassicaceae lineage I,we conclude the monophyletic origin of Al and Br S-loci and clarify the evolutionary route of S-loci in the Brassicaceae family.Our findings will contribute to evolutionary studies and breeding applications of the S-locus in Brassicaceae. | Yinan Cui Mu Zhuang Jian Wu Jisheng Liu Yiyue Zhang Lingkui Zhang Yile Huang Xu Cai Jianli Liang Kang Zhang Xiaowu Wang Feng Cheng | 2020 | Horticultural Plant Journal2020，6，3： | 2 |
| 5 | Understanding the phase separation characteristics of nucleocapsid protein provides a new therapeutic opportunity against SARS-CoV-2显示文摘Dear Editor To date,tens of millions of people have been infected with severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),causing the outbreak of the respiratory disease named the coronavirus disease 2019(COVID-19).As a newly emerged member of the coronavirus family,SARS-CoV-2 is an enveloped positive-strand RNA virus,which has probably the largest genome(approximately 30 kb)among all RNA viruses.The nucleocapsid(N)protein of SARS-CoV-2 is mainly responsible for recognizing and wrapping viral RNA into helically symmetric structures(Malik,2020). | Dan Zhao Weifan Xu Xiaofan Zhang Xiaoting Wang Yiyue Ge Enming Yuan Yuanpeng Xiong Shenyang Wu Shuya Li Nian Wu Tingzhong Tian Xiaolong Feng Hantao Shu Peng Lang Jingxin Li Fengcai Zhu Xiaokun Shen Haitao Li Pilong Li Jianyang Zeng | 2021 | Protein & Cell2021，12，9： | 1 |

| 7 | Highly Thermally Conductive Polymer/Graphene Composites with Rapid Room‑Temperature Self‑Healing Capacity显示文摘Composites that can rapidly self-healing their structure and function at room temperature have broad application prospects.However,in view of the complexity of composite structure and composition,its self-heal is facing challenges.In this article,supramolecular effect is proposed to repair the multistage structure,mechanical and thermal properties of composite materials.A stiff and tough supramolecular frameworks of 2-[[(butylamino)carbonyl]oxy]ethyl ester(PBA)–polydimethylsiloxane(PDMS)were established using a chain extender with double amide bonds in a side chain to extend prepolymers through copolymerization.Then,by introducing the copolymer into a folded graphene film(FGf),a highly thermally conductive composite of PBA–PDMS/FGf with self-healing capacity was fabricated.The ratio of crosslinking and hydrogen bonding was optimized to ensure that PBA–PDMS could completely self-heal at room temperature in 10 min.Additionally,PBA–PDMS/FGf exhibits a high tensile strength of 2.23±0.15 MPa at break and high thermal conductivity of 13±0.2 W m^(−1)K^(−1);of which the self-healing efficiencies were 100%and 98.65%at room temperature for tensile strength and thermal conductivity,respectively.The excellent self-healing performance comes from the efficient supramolecular interaction between polymer molecules,as well as polymer molecule and graphene.This kind of thermal conductive self-healing composite has important application prospects in the heat dissipation field of next generation electronic devices in the future. | Huitao Yu Can Chen Jinxu Sun Heng Zhang Yiyu Feng Mengmeng Qin Wei Feng | 2022 | Nano-Micro Letters2022，14，8： | 1 |

| 15 | A New Model of Interfacial Physical Contact in Diffusion Bonding显示文摘Through eliminating voids not affecting the primary bonding process, and incorporating interlayer and flexible base material, the interface geometry character and brief mathematics process were put forth. Through analyzing contact process of diffusion bonding, contact area model was settled. It can interpret the phenomenon of different interface areas taking on different strengths. In the course of physical contact, shear stresses serve an important function for the plastic deformation and the cohesion of interface voids. | Peng HE, Jicai FENG and Yiyu QIANNational Key Laboratory of Advanced Welding Production Technology, Harbin Institute of Technology, Harbin 150001, China | 2004 | Journal of Materials Science & Technology2004，20，1： | 1 |

| 18 | Population genomic analysis reveals domestication of cultivated rye from weedy rye显示文摘Rye(Secale cereale)is an important crop with multiple uses and a valuable genetic resource for wheat breeding.However,due to its complex genome and outcrossing nature,the origin of cultivated rye remains elusive.The geneticist N.I.Vavilov proposed that cultivated rye had been domesticated from weedy rye,rather than directly from wild species like other crops.Unraveling the domestication history of rye will extend our understanding of crop evolution and upend our inherent understanding of agricultural weeds.To this end,in this study we generated the 8.5 Tb of whole-genome resequencing data from 116 worldwide accessions of wild,weedy,and cultivated rye,and demonstrated that cultivated rye was domesticated directly from weedy relatives with a similar but enhanced genomic selection by humans.We found that a repertoire of genes that experienced artificial selection is associated with important agronomic traits,including shattering,grain yield,and disease resistance.Furthermore,we identified a composite introgression in cultivated rye from the wild perennial Secale strictum and detected a 2-Mb introgressed fragment containing a candidate ammonium transporter gene with potential effect on the grain yield and plant growth of rye.Taken together,our findings unravel the domestication history of cultivated rye,suggest that interspecific introgression serves as one of the likely causes of obscure species taxonomy of the genus Secale,and provide an important resource for future rye and wheat breeding. | Yanqing Sun Enhui Shen Yiyu Hu Dongya Wu Yu Feng Sangting Lao Chenfeng Dong Tianyu Du Wei Hua Chu-Yu Ye Jinhuan Zhu Qian-Hao Zhu Daguang Cai Lidia Skuza Jie Qiu Longjiang Fan | 2022 | Molecular Plant2022，15，3： | 1 |
| 19 | Ultrathin layered double hydroxide nanosheets prepared by original precursor method for photoelectrochemical photodetectors显示文摘Layered double hydroxides(LDHs)are widely used owing to their unique alternating anionic and cationic layered twodimensional(2D)structures.However,studies on the preparation of 2D LDH nanosheets with uniform thickness and their photodetectors are limited.In this study,two novel ultrathin LDH(Ca-In and Ca-Al LDH)nanosheets are peeled off from precursor bimetallic phosphides through the original precursor method.Both Ca-In and Ca-Al LDH nanosheets demonstrate a uniform thickness distribution with an average thickness of 3–4 nm,micron-level lateral sizes,and moderate bandgap.Owing to its broad light absorption range,hydrophilicity,and stability,Ca-In and Ca-Al LDH nanosheets are applied for the first time in photoelectrochemical photodetectors,realizing a wide range of light detection from ultraviolet(365 nm)to visible light(635 nm).Moreover,the fabricated photodetectors exhibit excellent cycle stability,and the average photocurrent density shows no reduction after 70 days.Therefore,this study provides an effective method to prepare 2D Ca-In and Ca-Al LDH nanosheets with uniform thickness and photoelectric application prospects. | Yu Wang Fulai Zhao Yiyu Feng Wei Feng | 2022 | Nano Research2022，15，10： | 1 |
