| 1 | Multi-scale inversion of density structure from gravity anomalies in Tarim Basin显示文摘Based on the power spectra of gravity anomalies in Tarim Basin, the anomalies can be decomposed to the following three components: a sub-anomaly formed mainly by the basin crystallized basement, a sub-anomaly formed mainly by deep sedimentary layers, and that by shallow sedimentary layers. A special wavelet transform analysis scheme and a density inversion method are designed and applied to the decomposition and inversion of gravity sub-anomalies, which are correlated with regional geology and drilling data. The results indicate that the deep and the shallow sub-anomalies show some relations with ancient fluid active zones. The negative density disturbances inversed from the shallow sub-anomaly are mainly caused by Mesozoic fluid active zones, whereas the negative density disturbances form the deep sub-anomalies are mainly correlated with Paleozoic fluid active zones. As the ancient fluid movement was good for formation of oil/gas fields, the multi-scale inversion methods for locating the ancient fluid movement zones seem to be helpful and valuable to oil/gas exploration. | HOU ZunZe YANG WenCai | 2011 | Science China Earth Sciences2011，54，3： | 30 |
| 2 | Microstructure and mechanical properties of NZ30K alloy by semi-continuous direct chill and sand mould casting processes显示文摘The Mg-3.0Nd-0.2Zn-0.4Zr (NZ30K) alloys were prepared by direct-chill casting (DCC) and sand mould casting (SMC) processes,respectively and their microstructures and mechanical properties were investigated.The results indicate that casting method plays a remarkable influence on the microstructure and mechanical properties of as-cast NZ30K alloy.The grain size increases from 35-40μm in the billets made by the DCC to about 100-120μm in the billets by the SMC.The aggregation of Mg12Nd usually found at the triple joints of grain boundaries in the billets prepared by SMC while is not observable from the billets by DCC.The tensile strengths and elongations of the billets are 195.2 MPa and 15.5% by DCC,and 162.5 MPa and 3.2% by SMC,respectively.The tensile strength of the alloy by DCC is remarkably enhanced by T6 heat treatment,which reached 308.5 MPa.Fracture surfaces of NZ30K alloy have been characterized as intergranular fracture by SMC and quasi-cleavage fracture by DCC,respectively. | Zheng Xingwei Dong Jie Liu Wencai Ding Wenjiang | 2011 | China Foundry2011，8，1： | 25 |
| 3 | Graphene: a promising 2D material for electrochemical energy storage显示文摘Graphene, with unique two-dimensional form and numerous appealing properties, promises to remarkably increase the energy density and power density of electrochemical energy storage devices(EESDs),ranging from the popular lithium ion batteries and supercapacitors to next-generation high-energy batteries. Here, we review the recent advances of the state-of-the-art graphene-based materials for EESDs,including lithium ion batteries, supercapacitors, micro-supercapacitors, high-energy lithium-air and lithium-sulfur batteries, and discuss the importance of the pore, doping, assembly, hybridization and functionalization of different nano-architectures in improving electrochemical performance. The major roles of graphene are highlighted as(1) a superior active material,(2) ultrathin 2D flexible support,and(3) an inactive yet electrically conductive additive. Furthermore, we address the enormous potential of graphene for constructing new-concept emerging graphene-enabled EESDs with multiple functionalities of lightweight, ultra-flexibility, thinness, and novel cell configurations. Finally, future perspectives and challenges of graphene-based EESDs are briefly discussed. | Yanfeng Dong Zhong-Shuai Wu Wencai Ren Hui-Ming Cheng Xinhe Bao | 2017 | Science Bulletin2017，62，10： | 22 |
| 4 | Effect of Y and Gd content on the microstructure and mechanical properties of Mg-Y-RE alloys显示文摘In the application of WE43,it is found that Y_(2)O_(3)inclusion formed in the process of casting seriously reduced the mechanical properties of the products.The reduction of the mechanical properties is even more distinct when it comes to the application in the thin walled complex-precision castings.In order to decrease the Y_(2)O_(3)inclusions,Gd element was used to replace part of the Y element in Mg-Y-RE series alloys.The effect of Y content(Mg-x Y-1Gd-2Nd-0.5Zn-0.5Zr)and Y/Gd ratio(Mg-x Y-(5-x)Gd-2Nd-0.5Zn-0.5Zr)on the microstructure and mechanical properties of Mg-Y-RE alloys were investigated in this paper.With decreasing Y content,the grain size of the alloys increased,both ultimate tensile strength(UTS)and yield strength(YS)of alloys decreased monotonically.Replacing part of Y content with Gd and keeping the total rare earth content unchanged,the low Y content Mg-2Y-3Gd-2Nd-0.5Zn-0.5Zr alloy showed the same mechanical properties as the high Y content Mg-4Y-1Gd-2Nd-0.5Zn-0.5Zr alloy at both room and elevated temperatures.After solution treatment at 525°C for 8 h and aging treatment at 225°C for 10 h,the UTS,YS and elongation(ε)of Mg-2Y-3Gd-2Nd-0.5Zn-0.5Zr alloy reached 281.7 MPa,198 MPa and 11.1%at room temperature,and 216.7 MPa,171.6 MPa and 16.1%at 250°C.The new low Y content Mg-2Y-2Nd-3Gd-0.5Zn-0.5Zr alloy is expected to replace the high Y content WE43 alloys,which can be used in the complex thin-walled parts of aviation products. | Kang Luo Liang Zhang Guohua Wu Wencai Liu Wenjiang Ding | 2019 | Journal of Magnesium and Alloys2019，7，2： | 20 |
| 5 | A Chromosome-Scale Genome Assembly of Paper Mulberry(Bmussonetia papyrifera)Provides New Insights into Its Forage and Papermaking Usage显示文摘Paper mulberry(Broussonetia papyrifera)is a well-known woody tree historically used for Cai Lun papermaking,one of the four great inventions of ancient China.More recently,Paper mulberry has also been used as forage to address the shortage of feedstuff because of its digestible crude fiber and high protein contents.In this study,we obtained a chromosome-scale genome assembly for Paper mulberry using integrated approaches,including Illumina and PacBio sequencing platform as well as Hi-C,optical,and genetic maps.The assembled Paper mulberry genome consists of 386.83 Mb,which is close to the estimated size,and 99.25%(383.93 Mb)of the assembly was assigned to 13 pseudochromosomes.Comparative genomic analysis revealed the expansion and contraction in the flavonoid and lignin biosynthetic gene families,respectively,accounting for the enhanced flavonoid and decreased lignin biosynthesis in Paper mulberry.Moreover,the increased ratio of syringyl-lignin to guaiacyl-lignin in Paper mulberry underscores its suitability for use in medicine,forage,papermaking,and barkcloth making.We also identified the rootassociated microbiota of Paper mulberry and found that Pseudomonas and Rhizobia were enriched in its roots and may provide the source of nitrogen for its stems and leaves via symbiotic nitrogen fixation.Collectively,these results suggest that Paper mulberry might have undergone adaptive evolution and recruited nitrogen-fixing microbes to promote growth by enhancing flavonoid production and altering lignin monomer composition.Our study provides significant insights into genetic basis of the usefulness of Paper mulberry in papermaking and barkcloth making,and as forage.These insights will facilitate further domestication and selection as well as industrial utilization of Paper mulberry worldwide. | Xianjun Peng Hui Liu Peilin Chen Feng Tang Yanmin Hu Fenfen Wang Zhi Pi Meiling Zhao Naizhi Chen Hui Chen Xiaokang Zhang Xueqing Yan Min Liu Xiaojun Fu Guofeng Zhao Pu Yao Lili Wang He Dai Xuming Li Wei Xiong Wencai Xu Hongkun Zheng Haiyan Yu Shihua Shen | 2019 | Molecular Plant2019，12，5： | 18 |
| 6 | Lithospheric seismic fabrics of Sulu ultrahigh-pressure metamorphic belt显示文摘Calibration of seismic reflectors appearing in the crust of the Chinese continent sci- entific drilling site can be completed through the correlation studies between direct evidences, such as the drill cores, and geophysical signatures; therefore the interpretation of geophysical data could produce reliable results of crustal structure and composition. On the other hand, there are two Cenozoic volcanoes close to the scientific drilling site; analyzing composition of xenoliths existent in the volcanoes and evaluating their seismic velocities can also offer information about the mantle and lower crust. After the calibration via cores and well-logging data, the seismic re- flectors appearing in the UHP belt can be caused by lithological changes within the UHP rock slice, ductile shearing rock-suites, and later fracture zones. Among these sources, ductile shearing resulted in displacement and detachment of original rock-sheets, producing some rock-interbeds of several hundred meters thick that are named the ductile shearing rock-suites. A suite consists of mylonized gneiss and eclogite slices that underwent shearing, becoming the major mechanism responsible to generate regional strong reflections. The UHP rock-slice is characterized by complicated structures and high density, high seismic velocity and high electri- cal resistivity, its thickness is usually less than 11 km. Velocity and density of the gneiss-layer beneath gradually tend to normal with increasing depth. Based on the xenoliths we can infer that the middle crust contains a lot of gneisses, and the lower crust consists of different granulites. The lithospheric mantle has multi-layer structures and consists mainly of spinal lherzolite and harzburgite, implying late Mesozoic lithospheric thinning. The seismic fabrics with different ori- gins were possible products of different geodynamic processes. For instance, the UHP rock-slice was produced by the UHP metamorphic process and the exhumation of subducted supercrustal rocks after the Triassic collision between the Yangtze and Sino-Korean cratons; whilst the ductile shearing rock-suites resulted from shearing deformation processes during the subduction and exhumation. The normal velocity below the UHP rock-slice was correlated with Mesozoic exten- sion processes in the area. Through careful calibration of seismic reflectors and analyzing xeno- liths, one can find the relationship between the causes of seismic reflectors and corresponding geodynamic processes, offering a new basis for reconstruction of regional dynamic evolution history. | YANG Wencai 1 , YANG Wuyang 1 , JIN Zhenmin 2 & CHENG Zhenyan 1 1.

| 7 | Discovering Crustal Deformation Bands by Processing Regional Gravity Field显示文摘Objectives:This article presents a new computational procedure to discover scratches buried in the earth's crust.We also validate this new interdisciplinary analysis method with regional gravity data located in a well-known Dabie orogenic zone for test.Methods:Based on the scratch analysis method evolved with mathematical morphology of surfaces,we present a procedure that extracts information of the crustal scratches from regional gravity data.Because the crustal scratches are positively and highly correlated to crustal deformation bands,it can be used for delineation of the crustal deformation belts.The scratches can be quantitatively characterized by calculation of the ridge coefficient function,whose high value traces delineate the deformation bands hidden in the regional gravity field.In addition,because the degree of crustal deformation is an important indicator of tectonic unit divisions,so the crust can be further divided according to the degree of crustal deformation into some tectonic units by using the ridge coefficient data,providing an objective base map for earth scientists to build tectonic models with quantitative evidence.Results:After the ridge coefficients are calculated,we can further enhance the boundary of high ridge-coefficient blocks,resulting in the so-called ridge-edge coefficient function.The high-value ridge-edge coefficients are well correlated with the edge faults of tectonic units underlay,providing accurate positioning of the base map for compilation of regional tectonic maps.In order to validate this new interdisciplinary analysis method,we select the Dabie orogenic zone as a pilot area for test,where rock outcrops are well exposed on the surface and detailed geological and geophysical surveys have been carried out.Tests show that the deformation bands and the tectonic units,which are conformed by tectonic scientists based on surface observations,are clearly displayed on the ridge and ridge-edge coefficient images obtained in this article.Moreover,these computer-generated images provide more accurate locations and geometric details.Conclusions:This work demonstrates that application of modern mathematical tools can promote the quantitative degree in research of modern geosciences,helping to open a door to develop a new branch of mathematical tectonics. | YANG Wencai SUN Yanyun | 2016 | Acta Geologica Sinica(English Edition)2016，90，1： | 11 |
| 8 | Improved Brassica rapa reference genome by single-molecule sequencing and chromosome conformation capture technologies显示文摘Brassica rapa comprises several important cultivated vegetables and oil crops.Current reference genome assemblies of Brassica rapa are quite fragmented and not highly contiguous,thereby limiting extensive genetic and genomic analyses.Here,we report an improved assembly of the B.rapa genome(v3.0)using single-molecule sequencing,optical mapping,and chromosome conformation capture technologies(Hi-C).Relative to the previous reference genomes,our assembly features a contig N50 size of 1.45 Mb,representing a~30-fold improvement.We also identified a new event that occurred in the B.rapa genome~1.2 million years ago,when a long terminal repeat retrotransposon(LTR-RT)expanded.Further analysis refined the relationship of genome blocks and accurately located the centromeres in the B.rapa genome.The B.rapa genome v3.0 will serve as an important community resource for future genetic and genomic studies in B.rapa.This resource will facilitate breeding efforts in B.rapa,as well as comparative genomic analysis with other Brassica species. | Lei Zhang Xu Cai Jian Wu Min Liu Stefan Grob Feng Cheng Jianli Liang Chengcheng Cai Zhiyuan Liu Bo Liu Fan Wang Song Li Fuyan Liu Xuming Li Lin Cheng Wencai Yang Mai-he Li Ueli Grossniklaus Hongkun Zheng Xiaowu Wang | 2018 | Horticulture Research2018，5，1： | 10 |
| 9 | High temperature mechanical behavior of low-pressure sand-cast Mg-Gd-Y-Zr magnesium alloy显示文摘The aim of this work is firstly to optimize T6 heat-treatment of low-pressure sand-cast Mg-10Gd-3Y-0.5Zr alloy,and then systematically investigate the mechanical behavior of the T6-treated alloy from room temperature to 300℃.It turned out that the optimum T6 heat-treatments for the tested alloy are 525℃×12 h+225℃×14 h and 525℃×12 h+250℃×12 h which integrated age-hardening and tensile properties into account,respectively.The strength of the T6-treated alloy indicates obvious anomalous temperature dependence from room temperature to 300℃,namely both ultimate tensile strength and yield strength of the tested alloy firstly increase with tensile temperature,and then decrease as temperature increases further.Elongation increased with temperature monotonously.The tensile fracture mode of the tested alloy changes from transgranular fracture to intergranular fracture with the increasing of test temperature. | Wencai Liu Beiping Zhou Guohua Wu Liang Zhang Xiang Peng Liang Cao | 2019 | Journal of Magnesium and Alloys2019，7，4： | 10 |
| 10 | Efficient Synthesis of Graphene Nanoribbons Sonochemically Cut from Graphene Sheets显示文摘We report a facile approach to synthesize narrow and long graphene nanoribbons (GNRs) by sonochemically cutting chemically derived graphene sheets (GSs). The yield of GNRs can reach ~5 wt% of the starting GSs. The resulting GNRs are several micrometers in length, with ~75% being single-layer, and ~40% being narrower than 20 nm in width. A chemical tailoring mechanism involving oxygen-unzipping of GSs under sonochemical conditions is proposed on the basis of experimental observations and previously reported theoretical calculations;it is suggested that the formation and distribution of line faults on graphite oxide and GSs play crucial roles in the formation of GNRs. These results open up the possibilities of the large-scale synthesis and various technological applications of GNRs. | Zhong-Shuai Wu Wencai Ren Libo Gao Bilu Liu Jinping Zhao Hui-Ming Cheng | 2010 | Nano Research2010，3，1： | 10 |

| 12 | Microstructure evolution of semi-solid Mg-10Gd-3Y-0.5Zr alloy during isothermal heat treatment显示文摘In this study,the microstructure evolution of semi-solid Mg-10Gd-3Y-0.5Zr alloy during isothermal heat treatment has been investigated.The results show that primary particles coarsen continuously during the holding.Coarsening rate decreases with the increase of isothermal temperature.When isothermal temperature increases from 600℃ to 620℃,the dominant mechanism for coarsening changes from particle coalescence to Ostwald ripening.Equiaxed as-cast microstructure is beneficial to the semi-solid microstructure after isothermal heat treatment,which brings about the refinement and spheroidization of primary particles,and shortening of holding time.Significant modification of second phases can also be achieved after isothermal heat treatment,due to its unique solidification process.The optimum processing parameters for Mg-10Gd-3Y-0.5Zr alloy in isothermal heat treatment are isothermal temperature of 610℃-620℃ and holding time of 20-40 min. | Guohua Wu Yang Zhang Wencai Liu Wenjiang Ding | 2013 | Journal of Magnesium and Alloys2013，1，1： | 8 |
| 13 | Geothermal measurements in the pilot-boreholes of the China Continental Scientific Drilling显示文摘The geothermal measurements in the pilot-boreholes of the China Continental Scientific Drilling (CCSD) indicate that the temperature gradients in the target area of the deep drilling range from 19 to 26℃/km, which is lower than that (25-30℃/km) for the global continental area and similar to that for the KTB (21-28℃/km). Thermal conductivity measurements for 44 core samples show that the ultra-high pressure (UHP) metamorphic rocks have 50% higher thermal conductivity (with a mean of 3.94±1.26 W/mK) than that for the average value of the upper crust. The measured heat flow values vary between 76 and 80 mW/m2, higher than that for the global continental area (65±1.6 mW/m2) and the continental China (61±15.5mW/m2) as well as the adjacent North Jiangsu Basin (68 mW/m2), butlower than that below 1000 m in the KTB (85 mW/m2). The elevated heat flow in the pilot-boreholes can be attributed to the lateral heat concentration due to higher rock thermal conductivity of the VHP belt than that of the adjacent | WANG Jiyang HU Shengbiao YANG Wencai CHEN Benhe CHEN Zhenyan LI Tiejun | 2001 | Chinese Science Bulletin2001，46，20： | 7 |
| 14 | Discovery and development of natural heat shock protein 90 inhibitors in cancer treatment显示文摘Heat shock protein 90(Hsp90)is a highly conserved molecular chaperone that plays a vital role in the signal transduction of cancers.Hsp90 inhibitors are able to inhibit Hsp90 or the complex of Hsp90 and co-chaperones resulting in the degradation of Hsp90-dependent client proteins through the ubiqui tina tion-proteasome pathway,thereby leading to the growth inhibition of tumor cells.This review will briefy discuss the molecular structure and biological function of Hsp90,and focus on a summary of recent progress in the development and testing of natural Hsp90 inhibitors and their different means by which they interact with Hsp90. | Yong Li Dongmei Zhang Jun Xu Junmin Shi Lei Jiang Nan Yao Wencai Ye | 2012 | Acta Pharmaceutica Sinica B2012，2，3： | 7 |
| 15 | Microstructural evolution,mechanical properties and corrosion behavior of as-cast Mg-5Li-3Al-2Zn alloy with different Sn and Y addition显示文摘Influences of Sn and Y on the microstructure,mechanical properties,and corrosion behavior of as-cast Mg-5 Li-3 Al-2 Zn(LAZ532)alloy were investigated.The addition of Sn and Y refines grains and results in the formation of Mg2 Sn and Al2 Y phases,thus improving the mechanical properties of alloy by second phase strengthening and grain refinement strengthening.As-cast LAZ532 alloy shows typical filiform corrosion morphology,and the addition of Sn and Y does not change the corrosion mode of alloy.Ascast LAZ532-0.8 Sn-1.2 Y alloy shows excellent mechanical properties with yield strength of 166.2 MPa,ultimate tensile strength of 228.6 MPa and elongation of 14.8%,and exhibits the best corrosion resistance with the smallest corrosion current density and the lowest anodic dissolution rate. | Xiang Peng Shihao Xu Dehua Ding Guanglan Liao Guohua Wu Wencai Liu Wenjiang Ding | 2021 | Journal of Materials Science & Technology2021，，13： | 7 |
| 16 | Controlling reduction degree of graphene oxide membranes for improved water permeance显示文摘Tailoring the pore structure and surface chemistry of graphene-based laminates is essentially important for their applications as separation membranes.Usually,pure graphene oxide(GO) and completely reduced GO(r GO) membranes suffer from low water permeance because of the lack of pristine graphitic sp^2 domains and very small interlayer spacing,respectively.In this work,we studied the influence of reduction degree on the structure and separation performance of r GO membranes.It was found that weak reduction retains the good dispersion and hydrophilicity of GO nanosheets.More importantly,it increases the number of pristine graphitic sp^2 domains in rGO nanosheets while keeping the large interlayer spacing of the GO membranes in most regions at the same time.The resultant membranes show a high water permeance of 56.3 L m^(-2)h^(-1)bar^(-1),which is about 4 times and over 10~4 times larger than those of the GO and completely reduced r GO membranes,respectively,and high rejection over 95% for various dyes.Furthermore,they show better structure stability and more superior separation performance than GO membranes in acid and alkali environments. | Qing Zhang Xitang Qian Khalid Hussain Thebo Hui-Ming Cheng Wencai Ren | 2018 | Science Bulletin2018，63，12： | 7 |
| 17 | Effect of rolling strain on microstructure and tensile properties of dual-phase Mg-8Li-3Al-2Zn-0.5Y alloy显示文摘This study was conducted to discuss the effect of rolling strain on microstructure and tensile properties of dual-phase Mg-8Li-3Al-2Zn-0.5 Y(wt%) alloy, which was prepared by casting, and then homogenized and rolled at 200℃. The rolling process was conducted with 10% reduction per pass and five different accumulated strains, varying from 10% to 70%. The results indicate that the as-cast and as-rolled Mg-8Li-3Al-2Zn-0.5Y alloys are composed of α-Mg, β-Li, AlLi and Al_2Y phases. After rolling process,anisotropic microstructure was observed. a-Mg phase got elongated in both rolling direction and transverse direction with the addition of rolling strain. Consequently, the strength of the alloy in both directions was notably improved whereas the elongation declined, mainly caused by strain hardening and dispersion strengthening. The tensile properties of the as-rolled alloys in the RD, no matter the YS, UTS or the elongation, are higher than those of the TD due to their larger deformation strain and significant anisotropy in the hcp α-Mg phase. In addition, the fracture and strengthening mechanism of the tested alloys were also investigated systematically. | Wencai Liu Shi Feng Zhongquan Li Jiong Zhao Guohua Wu Xianfei Wang Lv Xiao Wenjiang Ding | 2018 | Journal of Materials Science & Technology2018，34，12： | 6 |

| 20 | Breeding for Resistance to Tomato Bacterial Diseases in China:Challenges and Prospects显示文摘Four bacterial diseases including bacterial canker caused by Clavibacter michiganensis subsp. michiganensis, bacterial speck caused by Pseudomonas syringae pv. tomato, bacterial spot caused by at least four Xanthomonas species, and bacterial wilt caused by Ralstonia solanacearum are among the most devastating diseases in tomato(Solanum lycopersicum) production in China. However, almost no commercial cultivars currently growing in the country are resistant to these four bacterial diseases because little effort has been devoted to breeding for resistance. In addition,the existence of great natural variation in each pathogen and the quantitative inheritance of resistance add to the difficulties of developing cultivars with resistance to these diseases. In the past 20 years, molecular markers tightly linked to genes conferring resistance to these four bacterial diseases have been identified or gene-based markers have been developed, which may circumvent some of the problems associated with phenotypic selection for resistance to multiple bacterial pathogens and races. Here we present a review on current status of studies on these diseases and discuss the promise of new technologies in breeding for resistance to these bacterial diseases in China. | WANG Yuqing ZHANG Yaxian GAO Zhipeng YANG Wencai | 2018 | Horticultural Plant Journal2018，4，5： | 5 |
