| 1 | Finer-Resolution Mapping of Global Land Cover: Recent Developments, Consistency Analysis, and Prospects显示文摘Land-cover mapping is one of the foundations of Earth science.As a result of the combined efforts of many scientists,numerous global land-cover(GLC)products with a resolution of 30 m have so far been generated.However,the increasing number of fineresolution GLC datasets is imposing additional workloads as it is necessary to confirm the quality of these datasets and check their suitability for user applications.To provide guidelines for users,in this study,the recent developments in currently available 30 m GLC products(including three GLC products and thematic products for four different land-cover types,i.e.,impervious surface,forest,cropland,and inland water)were first reviewed.Despite the great efforts toward improving mapping accuracy that there have been in recent decades,the current 30 m GLC products still suffer from having relatively low accuracies of between 46.0%and 88.9%for GlobeLand30-2010,57.71%and 80.36%for FROM_GLC-2015,and 65.59%and 84.33%for GLC_FCS30-2015.The reported accuracies for the global 30 m thematic maps vary from 67.86%to 95.1%for the eight impervious surface products that were reviewed,56.72%to 97.36%for the seven forest products,32.73%to 98.3%for the six cropland products,and 15.67%to 99.7%for the six inland water products.The consistency between the current GLC products was then examined.The GLC maps showed a good overall agreement in terms of spatial patterns but a limited agreement for some vegetation classes(such as shrub,tree,and grassland)in specific areas such as transition zones.Finally,the prospects for fine-resolution GLC mapping were also considered.With the rapid development of cloud computing platforms and big data,the Google Earth Engine(GEE)greatly facilitates the production of global fine-resolution land-cover maps by integrating multisource remote sensing datasets with advanced image processing and classification algorithms and powerful computing capability.The synergy between the spectral,spatial,and temporal features derived from multisource satellite datasets and stored in cloud computing platforms will definitely improve the classification accuracy and spatiotemporal resolution of fineresolution GLC products.In general,up to now,most land-cover maps have not been able to achieve the maximum(per class or overall)error of 5%–15%required by many applications.Therefore,more efforts are needed toward improving the accuracy of these GLC products,especially for classes for which the accuracy has so far been low(such as shrub,wetland,tundra,and grassland)and in terms of the overall quality of the maps. | Liangyun Liu Xiao Zhang Yuan Gao Xidong Chen Xie Shuai Jun Mi | 2021 | Journal of Remote Sensing2021，，1： | 9 |
| 2 | Atomic structures of Zr-based metallic glasses显示文摘The atomic structures of Zr-Ni and Zr-Ti-Al-Cu-Ni metallic glasses were investigated by using classical molecular dynamic (MD),reverse Monte Carlo (RMC),ab initio MD (AIMD) simulations and high resolution transmission electron microscopy (HRTEM) techniques. We focused on the short-range order (SRO) and medium-range order (MRO) in the glassy structure. It is shown that there are icosahedral,FCC-and BCC-type SROs in the Zr-based metallic glasses. A structural model,characterized by imperfect ordered packing (IOP),was proposed based on the MD simulation and confirmed by the HRTEM observation. Furthermore,the evolution from IOP to nanocrystal during the crystallization of metallic glasses was also ex-plored. It is found that the growth from IOP to nanocrystal proceeds through three distinct stages: the formation of quasi-ordered structure with one-dimensional (1D) periodicity,then 2D periodicity,and finally the formation of 3D nanocrystals. It is also noted that these three growth steps are crosslinked. | HUI XiDong LIU XiongJun GAO Rui HOU HuaiYu FANG HuaZhi LIU ZiKui CHEN GuoLiang | 2008 | Science China(Physics,Mechanics & Astronomy)2008，51，4： | 8 |
| 3 | Tunable Schottky barrier width and enormously enhanced photoresponsivity in Sb doped SnS2 monolayer显示文摘Doping, which is the intentional introducti on of impurities into a material, can improve the metal-semiconductor interface by reducing Schottky barrier width. Here, we prese nt high-quality two-dime nsional SnS2 nano sheets with well-controlled Sb dopi ng concen tration via direct vapor growth approach and following micromechanical cleavage process. X-ray photoelectro n spectroscopy (XPS) measureme nt dem on strates that Sb contents of the doped samples are approximately 0.22%, 0.34% and 1.21%, respectively, and doping in duces the upward shift of the Fermi level with respect to the pristi ne SnS2. Tran smissio n electro n microscopy (TEM) characterizatio n exhibits that Sb-doped SnS2 nano sheets have a high-quality hexagonal symmetry structure and Sb element is uniformly distributed in the nano sheets. The phototra nsistors based on the Sb-doped SnS2 mono layers show n-type behavior with high mobility which is one order of magn itude higher than that of pristi ne SnS2 phototra nsistors. The photorespo nsivity and exter nal quantum efficiency (EQE) of Sb-S nS2 mono layers phototra nsistors are approximately three orders of magnitude higher than that of pristine SnS2 phototransistor. The results suggest that the method of reducing Shottky barrier width to achieve high mobility and photoresp on sivity is effective, and Sb-doped SnS2 mono layer has significant potential in future nanoelectronic and optoelectronic applications. | Junchi Liu Xiao Liu Zhuojun Chen Lili Miao Xingqiang Liu Bo Li Liming Tang Keqiu Chen Yuan Liu Jingbo Li Zhongming Wei Xidong Duan | 2019 | Nano Research2019，12，2： | 7 |
| 4 | Magnetocaloric effect in Er-Al-Co bulk metallic glasses显示文摘A series of Er-Al-Co bulk metallic glasses (BMGs) have been prepared by the copper mold casting method. The glass forming ability and magnetocaloric effect (MCE) for these alloys have been investigated. The second-order magnetic transition from para-magnetic to ferromagnetic states takes place at about 9 K. These BMGs exhibit excellent MCE because of their large effective magneton number; Er56Al24Co20 BMG has a maximum entropy change and refrigeration capacity of 16.06 J kg-1 K-1 and 546 J kg-1,respectively,under the field of 50 kOe (10 kOe=795.775 kA/m) indicating that these BMGs are potential candidate magnetic materials for hydrogen liquefaction. | HUI XiDong XU ZhiYi WU Yuan CHEN XiaoHua LIU XiongJun LU ZhaoPing | 2011 | Chinese Science Bulletin2011，56，36： | 6 |
| 5 | Exosomal miRNA profiling before and after surgery revealed potential diagnostic and prognostic markers for lung adenocarcinoma显示文摘Exosome is a crucial manner for cancer cell to cell communication and circulating exosomes sever as promising diagnostic and prognostic markers for various types of diseases.A predominant type of cargo of exosome is small RNAs,especially miRNAs.Here,we profiled plasma exosomal miRNAs of six lung adenocarcinoma patients before and after surgery,as well as six healthy individuals as normal control.Our profiling revealed 38 upregulated and 37 downregulated exosomal miRNAs in the plasma of lung adenocarcinoma patients.Additionally,we found that most upregulated miRNAs were increased in the lung adenocarcinoma samples of TCGA database.We further evaluated the correlation between the upregulated exosomal miRNAs and overall survival with Kaplan-Meier survival analysis using online databases.Our resu ltS suggested that exosomal miR-151a-5p,miR-10b-5p,miR-192-5p,miR-106b-3p,and miR-484 are potential prognostic markers for lung adenocarcinoma.Importantly,we validated candidate miRNAs in lung adenocarcinoma patients before and after surgery as well as in healthy controls and found that miR-484 was significantly increased in the plasma of lung adenocarcinoma patients and strikingly decreased post-surgery.Hence,we provided novel information on lung adenocarcinoma-derived exosomal miRNA and potential non-invasive diagnostic and prognostic markers for lung adenocarcinoma. | Xinying Xue Chen Wang Zhiqiang Xue Jiaxin Wen Jun Han Xidong Ma Xuelei Zang Hui Deng Rui Guo Idorenyin Polycarp Asuquo Chong Qin Haijiao Wang Quansheng Gao Sanhong Liu Jianxin Wang | 2020 | Acta Biochimica et Biophysica Sinica2020，52，3： | 6 |
| 6 | Maturity Control on the Patterns of Hydrocarbon Regeneration from Coal显示文摘Rock-Eval pyrolysis and Py-GC experiments on naturally and artificially matured coal samples were carried out. The results suggest that both depolymerization and defuctionalization exist during the maturation and evolution of coal. The patterns of hydrocarbon regeneration are diverse at different stages of the maturation and evolution. When the vitrinite reflectance (R0) is 0.7%-0.9%, bitumen is the richest in coal while activation energy is the minimum, and the temperature of peak yield is lower than that of primary hydrocarbon generation. However, if reflectance is greater than 0.9%, defunctionalization predominates and the temperature of peak regeneration is shown in lagging compared with the primary hydrocarbon generation. When reflectance is out of the 'oil window', the peak temperature of hydrocarbon regeneration and that of the primary hydrocarbon generation seems to be continuous. | ZOU Yanrong YANG Qi LIU Dameng KANG Xidong TANG Dazhen | 2000 | Acta Geologica Sinica(English Edition)2000，74，2： | 6 |
| 7 | High-performance asymmetric electrodes photodiode based on Sb/WSe2 heterostructure显示文摘Two-dimensional (2D) van der Waals (vdWs) metal-semiconductor heterostructures with atomically sharp interface and matched work functions have recently attracted great attention due to their unique electronic and optoelectronic properties. Here we report the vapor phase epitaxial growth of large-scale vertical Sb/WSe2 metal-semiconductor vdWs heterostructures with uniform stacking orientation. Compared with the growth on S1O2/S1 substrate, the thick ness of Sb nan osheet on WSe2 can be reduced effectively to mono layer. We con struct Sb-WSe2-Au asymmetric electrodes photodiode based on the Sb/WSe2 heterostructures. Electrical transport measurements indicate that the photodiode show obvious rectifying effect. Optoelectronic characterizations show prominent photoresponse with a high photoresposivity of 364 mA/W, a fast response time of less than 8 ms, a large open-circuit voltage of 0.27 V and a maximum electrical power output of 0.11 nW. The direct growth of high-quality metal-semiconductor vdWs heterostructures may open up new realms in 2D functional electronics and optoelectronics. | Xiao Liu Guangzhuang Sun Peng Chen Junchi Liu Zhengwei Zhang Jia Li Huifang Ma Bei Zhao Ruixia Wu Weiqi Dang Xiangdong Yang Chen Dai Xuwan Tang Zhuojun Chen Lili Miao Xingqiang Liu Bo Li Yuan Liu Xidong Duan | 2019 | Nano Research2019，12，2： | 5 |
| 8 | van der Waals epitaxial growth of ultrathin metallic NiSe nanosheets on WSe2 as high performance contacts for WSe2 transistors显示文摘A prerequisite for widespread applications of atomically thin transition metal dichalcogenides in future electronics is to achieve reliable electrical contacts,which is of considerable challenge due to the difficulties in selectively doping and inevitable physical damages of these atomically thin materials during typical metal integration process.Here,we report the in situ growth of ultrathin metallic NiSe single crystals on WSe2 in which the metallic NiSe nanosheets function as the contact electrodes to WSe2,creating an interface that is essentially free from chemical disorder.The NiSe/WSe2 heterostructures also exhibit well-aligned lattice orientation between the two layers,forming a periodic Moire pattern.Electrical transport studies demonstrate that the NiSe nanosheets exhibit an excellent metallic feature,as evidenced by the extra-high electrical conductivity of up to 1.6×10^6 S-nf1.The WSe2 transistors with the NiSe contact show field-effect mobilities (/vFe) more than double that with Cr/Au electrodes.This study demonstrates an effective pathway to achieve reliable electrical contacts to the atomically thin 2D materials,and maybe readily extended for fabricating 2D/2D low-resistance contacts for a variety of transition metal dichalcogenides. | Bei Zhao Weiqi Dang Xiangdong Yang Jia Li Haihong Bao Kai Wang Jun Luo Zhengwei Zhang Bo Li Haipeng Xie Yuan Liu Xidong Duan | 2019 | Nano Research2019，12，7： | 4 |
| 9 | Ultrafast growth of large single crystals of monolayer WS2 and WSe2显示文摘Monolayer transition metal dichalcogenides(TMDs)have attracted considerable attention as atomically thin semiconductors for the ultimate transistor scaling.For practical applications in integrated electronics,large monolayer single crystals are essential for ensuring consistent electronic properties and high device yield.The TMDs available today are generally obtained by mechanical exfoliation or chemical vapor deposition(CVD)growth,but are often of mixed layer thickness,limited single crystal domain size or have very slow growth rate.Scalable and rapid growth of large single crystals of monolayer TMDs requires maximization of lateral growth rate while completely suppressing the vertical growth,which represents a fundamental synthetic challenge and has motivated considerable efforts.Herein we report a modified CVD approach with controllable reverse flow for rapid growth of large domain single crystals of monolayer TMDs.With the use of reverse flow to precisely control the chemical vapor supply in the thermal CVD process,we can effectively prevent undesired nucleation before reaching optimum growth temperature and enable rapid nucleation and growth of monolayer TMD single crystals at a high temperature that is difficult to attain with use of a typical thermal CVD process.We show that monolayer single crystals of 450μm lateral size can be prepared in 10 s,with the highest lateral growth rate up to 45μm/s.Electronic characterization shows that the resulting monolayer WSe2 material exhibits excellent electronic properties with carrier mobility up to 90 cm^2 V^-1 s^-1,comparable to that of the best exfoliated monolayers.Our study provides a robust pathway for rapid growth of high-quality TMD single crystals. | Zhengwei Zhang Peng Chen Xiangdong Yang Yuan Liu Huifang Ma Jia Li Bei Zhao Jun Luo Xidong Duan Xiangfeng Duan | 2020 | National Science Review2020，7，4： | 4 |

| 11 | Evaluation on monthly sea surface wind speed of four reanalysis data sets over the China seas after 1988显示文摘This study investigates the long-term changes of monthly sea surface wind speeds over the China seas from 1988 to 2015. The 10-meter wind speeds products from four major global reanalysis datasets with high resolution are used: Cross-Calibrated Multi-Platform data set(CCMP), NCEP climate forecast system reanalysis data set(CFSR),ERA-interim reanalysis data set(ERA-int) and Japanese 55-year reanalysis data set(JRA55). The monthly sea surface wind speeds of four major reanalysis data sets have been investigated through comparisons with the longterm and homogeneous observation wind speeds data recorded at ten stations. The results reveal that(1) the wind speeds bias of CCMP, CFSR, ERA-int and JRA55 are 0.91 m/s, 1.22 m/s, 0.62 m/s and 0.22 m/s, respectively.The wind speeds RMSE of CCMP, CFSR, ERA-int and JRA55 are 1.38 m/s, 1.59 m/s, 1.01 m/s and 0.96 m/s,respectively;(2) JRA55 and ERA-int provides a realistic representation of monthly wind speeds, while CCMP and CFSR tend to overestimate observed wind speeds. And all the four data sets tend to underestimate observed wind speeds in Bohai Sea and Yellow Sea;(3) Comparing the annual wind speeds trends between observation and the four data sets at ten stations for 1988-1997, 1988–2007 and 1988–2015, the result show that ERA-int is superior to represent homogeneity monthly wind speeds over the China seaes. | Guosong Wang Xidong Wang Hui Wang Min Hou Yan Li Wenjing Fan Yulong Liu | 2020 | Acta Oceanologica Sinica2020，39，1： | 3 |
| 12 | The calmodulin-dependent protein kinase II inhibitor KN-93 protects rat cerebral cortical neurons from N-methyl-D-aspartic acid-induced injury显示文摘In this study, primary cultured cerebral cortical neurons of Sprague-Dawley neonatal rats were treated with 0.25, 0.5, and 1.0 μM calmodulin-dependent protein kinase II inhibitor KN-93 after 50 μM N-methyl-D-aspartic acid-induced injury. Results showed that, compared with N-methyl-D-aspartic acid-induced injury neurons, the activity of cells markedly increased, apoptosis was significantly reduced, leakage of lactate dehydrogenase decreased, and intracellular Ca(2+) concentrations in neurons reduced after KN-93 treatment. The expression of caspase-3, phosphorylated calmodulin-dependent protein kinase II and total calmodulin-dependent protein kinase II protein decreased after KN-93 treatment. And the effect was apparent at a dose of 1.0 μM KN-93. Experimental findings suggest that KN-93 can induce a dose-dependent neuroprotective effect, and that the underlying mechanism may be related to the down-regulation of caspase-3 and calmodulin-dependent protein kinase II expression. | Xuewen Liu Cui Ma Ruixian Xing Weiwei Zhang Buxian Tian Xidong Li Qiushi Li Yanhui Zhang | 2013 | Neural Regeneration Research2013，8，2： | 3 |
| 13 | Direct van der Waals epitaxial growth of 1D/2D Sb2Se3/WS2 mixed-dimensional p-n heterojunctions显示文摘The mixed-dimensional integration of two-dimensional (2D) materials with non-2D materials can give rise to prominent advances in performance or function.To date,the mixed-dimensional one-dimensional (1D)/2D heterostructures have been fabricated using various physical assembly approaches.However,direct epitaxial growth method which has notable advantages in preparing large-scale products and obtaining perfect interfaces is rarely investigated.Herein,we demonstrate for the first time the direct synthesis of the 1D/2D mixed-dimensional heterostructures by sequential vapor-phase growth of Sb2Se3 nanowires on WS2 monolayers.X-ray diffraction (XRD) pattern and Raman spectrum confirm the composition of the Sb2Se3/NS2 heterostructures.Transmission electron microscope (TEM) measurement demonstrates high quality of the heterostructures.Electrical transport characterization reveals that Sb2Se3 nanowire exhibits p-type characteristic and that WS2 monolayer exhibits n-type behavior,and that the p-n diode from 1D/2D mixed-dimensional Sb2Se3/WS2 heterostructure possesses obvious current rectification behavior.Optoelectronic measurements of the heterostructures show apparent photovoltaic response with an open-circuit voltage of 0.19 V,photoresponsivity of 1.51 A/W (Vds =5 V) and fast response time of less than 8 ms.The van der Waals epitaxial growth mode of Sb2Se3 nanowires on WS2 monolayers is verified by stripping the Sb2Se3 nanowire from the heterostructures using tape.Together,the direct van der Waals epitaxy opens a facile pathway to 1D/2D mixed-dimensional heterostructures for functional electronic and optoelectronic devices. | Guangzhuang Sun Bo Li Jia Li Zhengwei Zhang Huifang Ma Peng Chen Bei Zhao Ruixia Wu Weiqi Dang Xiangdong Yang Xuwan Tang Chen Dai Ziwei Huang Yuan Liu Xidong Duan Xiangfeng Duan | 2019 | Nano Research2019，12，5： | 2 |
| 14 | Study on liquids diffusion into and relevant corrosion behaviour of glass fibre reinforced polymer used in high voltage composite insulator显示文摘Long-term liquids diffusion tests were performed on glass fibre reinforced polymer(GFRP)used in high voltage composite insulator.The plate-shaped GFRP specimens were immersed in three types of liquids,which high voltage composite insulator would encounter in practice,including deionised water,NaCl solution and nitric acid solution for a period of 4000 h.Chemical reaction and physical dissolution complicated the diffusion processes,which could be divided into three types based on the features of diffusion curves.Fourier transform infrared spectroscopy,scanning electron microscopy and optical interferometry were employed to investigate the chemical property,two-dimensional(2D)and 3D surface morphologies of GFRP.The results revealed that the surface layer of GFRP was destroyed to some extent depending on the type and concentration of the liquid,the maximum of profile height deviation of GFRP surface was proposed to evaluate the extent of the corrosion of GFRP,the greater the profile height deviation,the more serious the corrosion of GFRP.The present work is helpful for a better understanding of the diffusion behaviour of liquids into GFRP used in high voltage composite insulator as well as in other industry applications. | Yanfeng Gao Xidong Liang Weining Bao Chao Wu Shaohua Li Yingyan Liu Yuanji Cai | 2020 | High Voltage2020，5，1： | 2 |
| 15 | Paleomagnetism and paleoclimate change in the South China Sea since the late Pleistocene显示文摘Signal processing techniques of cross-correlation, power spectral analysis and cross-power spectral analysis are used to determine the relationships between paleomagnetic properties and the oxygen isotope record of the South China Sea during the late Pleistocene. On the basis of correlation tests between the δ18O time series of cores V3 and A15 with the paleomagnetic properties of core SCS01, five events of susceptibility and intensity of natural remanent magnetization are identified as glacial events corresponding to δ18O positive events. The magnetic properties of the sediments which are independent of the geomagnetic field are sensitive climatic indicators which have frequencies corresponding to the Milankovitch orbital parameters. | Xidong Chen, Douglas F.

| 17 | Enhanced dynamic deformability and strengthening effect via twinning and microbanding in high density NiCoFeCrMoW high-entropy alloys显示文摘High density alloys with enhanced deformability and strength are urgently required in energy,military and nuclear industries,etc.In this work,we present a new kind of NiCoFeCrMoW high entropy alloys(HEAs)which possess higher densities and sound velocities than copper.We systematically investigate the phase structure,quasi-static tensile,dynamic compression and related deformation mechanism of these HEAs.It is shown that single FCC or FCC+μdual phases were formed in the HEAs depending on Mo and W content and annealing temperature.Excellent quasi-static tensile and dynamic compression properties have been achieved for these HEAs,e.g.Ni_(30)Co_(30)Fe_(21)Cr_(10)W_(9)HEA annealed at 1573 K exhibited a yield and ultimate tensile strength and elongation of~364 MPa,~866 MPa and~32%,respectively,in quasi-static test;a yield strength of~710 MPa and no fracture under the dynamic strain rate of 4100 s^(-1).Superior strain rate sensitivity(SRS)of yield strength than that of previously reported FCC HEAs have been evidenced.The dynamic stress-strain constitutive relation can be described by the modified Johnson-Cook model.As for the dynamic deformation mechanism,it is envisaged that the regulation of stacking fault energy and Peierls barrier in current HEAs resulted in occurrences of abundant nanoscale deformation twins and microbands during high strain rate compression.The synergistic microbanding and twinning effectively contributes to the enhanced dynamic deformability and strengthening effect.Besides,the interactions of dislocations with precipitates,stacking faults(SFs)with twins,and between SFs also contribute to extraordinary work-hardening capacity. | Xuli Liu Yidong Wu Yansong Wang Jinbin Chen Rui Bai Lei Gao Zhe Xu William Yi Wang Chengwen Tan Xidong Hui | 2022 | Journal of Materials Science & Technology2022，，32： | 1 |

| 19 | In-plane epitaxial growth of 2D CoSe-WSe2 metalsemiconductor lateral heterostructures with improved WSe2 transistors performance显示文摘The two-dimensional(2D)in-plane(lateral)heterostructures have attracted increasing interest for potential applications in the atomically thin electronics and optoelectronics.While most studies focus on semiconductorsemiconductor lateral heterostructures with highly similar lattice structures between the constituent components,the synthesis of metal-semiconductor lateral heterostructures is much less explored and usually more challenging due to more distinct lattice structures or chemical properties.Herein,a vapor phase epitaxy growth method of high-quality metal-semiconductor lateral heterostructures between tetragonal CoSe and hexagonal WSe2 is reported.The 2D CoSe can selectively nucleate at the edge of pre-grown WSe2 nanosheets to form CoSe-WSe2 metal-semiconductor lateral heterostructures.Optical microscopy(OM),scanning electron microscopy(SEM),and atomic force microscopy(AFM)studies reveal distinct contrast across the heterostructure interface.High-resolution transmission electron microscopy(HRTEM)and selected area electron diffraction(SAED)studies further confirm the microstructure modulation across the heterostructure interface.The field-effect transistors(FETs)of CoSe-WSe2 lateral heterostructures show satisfactory Ohmic contacts and considerably better FET performance over those with deposited Cr/Au contacts,suggesting the in-plane metal-semiconductor junctions may function as improved contacts for the atomically thin electronics. | Huifang Ma Kejing Huang Ruixia Wu Zhengwei Zhang Jia Li Bei Zhao Chen Dai Ziwei Huang Hongmei Zhang Xiangdong Yang BoLi Yuan Liu Xiangfeng Duan Xidong Duan | 2021 | InfoMat2021，3，2： | 1 |
