| 1 | Evolution and molecular epidemiology of foot-and-mouth disease virus in China显示文摘Foot-and-mouth disease (FMD),caused by foot-and-mouth disease virus (FMDV),is considered one of the most important viral diseases of cloven-hoofed animals,causing severe economic losses in affected regions of the world.Three serotypes (A,O,and Asia 1) of FMDV have been identified in China since 1958.In addition,the occurrence of novel subtypes within these serotypes has made the epidemiology of FMDV more complicated over the last few years.In this review,we summarize the history and the current epidemiological situation in China,genetic diversity (e.g.,quasispecies dynamics,antigenic heterogeneity,and functional constraints),intertypic recombination,and the evidence for positive selection of different FMDV serotypes.We also assess these genetic data to understand the origin,evolution,and transmission of FMDV,the findings of which may be useful in developing control measures for future epidemics. | BAI XingWen LI PingHua BAO HuiFang LIU ZaiXin LI Dong LU ZengJun CAO YiMei SHANG YouJun SHAO JunJun CHANG HuiYun LUO JianXun LIU XiangTao | 2011 | Chinese Science Bulletin2011，56，21： | 7 |
| 2 | Chemical Synthesis Residual Pyrolysis and Combustion: Kinetics and Evolved Gases Investigated by TG-FTIR显示文摘Chemical synthetic residual is one of the solid wastes generated from pharmaceutical industry.The pyrolysis and combustion characteristics of chemical synthesis residual were investigated using a thermogravimetric analyser coupled with Fourier transform infrared spectroscopy(TG-FTIR)in this study.The processes of pyrolysis and combustion can be divided into three stages.The average weight loss rate of pyrolysis process at low temperature was higher than that of combustion.The kinetic parameters of chemical synthesis residual during pyrolysis and combustion were calculated based on the TG results.Acetic acid and 4-aminophenol were the main evolved matter observed in the pyrolysis process.The emission characteristics of combustion at low temperature were similar to that of the pyrolysis,while CO2 was found as the major gaseous product at high temperature.A high temperature about 850°C is needed to make sure the complete combustion of chemical synthesis residual. | FANG Chunqi JIANG Xuguang LV Guojun YAN Jianhua LIN Xuliang SONG Huibo CAO Junjun | 2020 | Journal of Thermal Science2020，29，1： | 3 |
| 3 | China's battery electric vehicles lead the world:achievements in technology system architecture and technological breakthroughs显示文摘Developing new energy vehicles has been a worldwide consensus,and developing new energy vehicles characterized by pure electric drive has been China's national strategy.After more than 20 years of high-quality development of China's electric vehicles(EVs),a technological R&D layout of“Three Verticals and Three Horizontals”has been created,and technological advantages have been accumulated.As a result,China's new energy vehicle market has ranked first in the world since 2015.To systematically solve the key problems of battery electric vehicles(BEVs)such as“driving range anxiety,long battery charging time,and driving safety hazards”,China took the lead in putting forward a“system engineering-based technology system architecture for BEVs”and clarifying its connotation.This paper analyzes the research status and progress of the three core components of this architecture,namely,“BEV platform,charging/swapping station,and real-time operation monitoring platform”,and their key technological points.The three major demonstration projects of the 2008 Beijing Olympic Games,the 2022 Beijing Winter Olympics,and the intelligent and connected autonomous battery electric bus project are discussed to specify the applications of BEVs in China.The key research directions for upgrading BEV technologies remain to be further improving the vehicle-level all-climate environmental adaptability and all-day safety of BEVs,systematically solving the charging problem of BEVs and improving their application convenience,and safeguarding safety with early warning and implementing active/passive safety protection for the whole life cycle of power batteries on the basis of BEVs'operation big data.BEVs have acquired new technological features such as intelligent and networked technology empowerment,extensive integration of control-by-wire systems,a platform of chassis hardware,and modularization of functional software. | Hongwen He Fengchun Sun Zhenpo Wang Cheng Lin Chengning Zhang Rui Xiong Junjun Deng Xiaoqing Zhu Peng Xie Shuo Zhang Zhongbao Wei Wanke Cao Li Zhai | 2022 | Green Energy and Intelligent Transportation2022，1，1： | 2 |
| 4 | Radiation-hardened property of single-walled carbon nanotube film-based field-effect transistors under low-energy proton irradiation显示文摘Strong C-C bonds,nanoscale cross-section and low atomic number make single-walled carbon nanotubes(SWCNTs)a potential candidate material for integrated circuits(ICs)applied in outer space.However,very little work combines the simulation calculations with the electrical measurements of SWCNT field-effect transistors(FETs),which limits further understanding on the mechanisms of radiation effects.Here,SWCNT film-based FETs were fabricated to explore the total ionizing dose(TID)and displacement damage effect on the electrical performance under low-energy proton irradiation with different fluences up to 1×1015 p/cm2.Large negative shift of the threshold voltage and obvious decrease of the on-state current verified the TID effect caused in the oxide layer.The stability of the subthreshold swing and the off-state current reveals that the displacement damage caused in the CNT layer is not serious,which proves that the CNT film is radiation-hardened.Specially,according to the simulation,we found the displacement damage caused by protons is different in the source/drain contact area and channel area,leading to varying degrees of change for the contact resistance and sheet resistance.Having analyzed the simulation results and electrical measurements,we explained the low-energy proton irradiation mechanism of the CNT FETs,which is essential for the construction of radiation-hardened CNT film-based ICs for aircrafts. | Xiaorui Zhang Huiping Zhu Song’ang Peng Guodong Xiong Chaoyi Zhu Xinnan Huang Shurui Cao Junjun Zhang Yunpeng Yan Yao Yao Dayong Zhang Jingyuan Shi Lei Wang Bo Li Zhi Jin | 2021 | Journal of Semiconductors2021，42，11： | 2 |
| 5 | Gas Sensitivity of In0.3Ga0.7As Surface QDs Coupled to Multilayer Buried QDs显示文摘A detailed analysis of the electrical response of In0.3Ga0.7As surface quantum dots(SQDs)coupled to 5-layer buried quantum dots(BQDs)is carried out as a function of ethanol and acetone concentration while temperature-dependent photoluminescence(PL)spectra are also analyzed.The coupling structure is grown by solid source molecular beam epitaxy.Carrier transport from BQDs to SQDs is confirmed by the temperature-dependent PL spectra.The importance of the surface states for the sensing application is once more highlighted.The results show that not only the exposure to the target gas but also the illumination affect the electrical response of the coupling sample strongly.In the ethanol atmosphere and under the illumination,the sheet resistance of the coupling structure decays by 50%while it remains nearly constant for the reference structure with only the 5-layer BQDs but not the SQDs.The strong dependence of the electrical response on the gas concentration makes SQDs very suitable for the development of integrated micrometer-sized gas sensor devices. | Guodong WANG Zengguang LIU Junjun WANG Yingli YANG Xiaolian LIU Xinran ZHANG Liwei ZHANG Guohua CAO | 2020 | Photonic Sensors2020，10，3： | 1 |

The results showed that the content of erucic acid and oleic acid were significantly negatively correlated,the contents of erucic acid and glucosinolate were significantly positively correlated,while the contents of oleic acid and glucosinolate were significantly negatively correlated; principal component analysis( PCA) were performed on the population materials,factors 1 and 2 were extracted for plotting,factor 1 and factor 2 could explain 73. 7% and 23. 2% of the phenotypic variation,respectively; through cluster analysis,79 materials aggregated to form group I,and five special variants deviated from the population. The variation of erucic acid,oleic acid and glucosinolates in B. rapa populations was rich and there was significant correlation. Through cluster analysis,five excellent B. rapa breeding materials( No. 32,No. 45,No. 46,No. 50,and No. 59) were screened. | Entang TIAN Hailun LIANG Junjun WANG Jun GUO Huilin CAO Shuchun LIN | 2018 | Asian Agricultural Research2018，10，6： | 0 |
| 8 | A comprehensive first-principle study of borophene-based nano gas sensor with gold electrodes显示文摘Using density functional theory combined with nonequilibrium Green’s function method,the transport properties of borophene-based nano gas sensors with gold electrodes are calculated,and comprehensive understandings regarding the effects of gas molecules,MoS2 substrate and gold electrodes to the transport properties of borophene are made.Results show that borophene-based sensors can be used to detect and distinguish CO,NO,NO2 and NH3 gas molecules,MoS2 substrate leads to a nonlinear behavior on the current-voltage characteristic,and gold electrodes provide charges to borophene and form a potential barrier,which reduced the current values compared to the current of the systems without gold electrodes.Our studies not only provide useful information on the computationally design of borophene-based gas sensors,but also help understand the transport behaviors and underlying physics of 2D metallic materials with metal electrodes. | Yueyue Tian Houping Yang Junjun Li Shunbo Hu Shixun Cao Wei Ren Yin Wang | 2022 | Frontiers of physics2022，17，1： | 0 |

| 10 | Intermediate phase assisted sequential deposition of reverse-graded quasi-2D alternating cation perovskites for MA-free perovskite solar cells显示文摘One-step deposition approaches have been widely applied and developed in the fabrication of quasi-2D perovskites.However,the regulation of quantum wells(QWs)and crystalline orientation is difficult and complicated when using this methodology.Sequential deposition is another widespread synthetic approach for preparing perovskite films and perovskite dimension engineering.In this article,δ-CsPbI_(3)intermediate phase assisted sequential(IPAS)deposition is successfully carried out to fabricate MA-free quasi-2D ACI perovskites.The amount of theδ-CsPbI_(3)intermediate phase in the PbI2 layer and the concentration of GAI molecule in the IPA solution both play important roles in the production of MA-free quasi-2D ACI perovskite films.The n value of the MA-free quasi-2D ACI perovskites can be adjusted,which affects the photovoltaic performance and device stability.Compared with one-step deposition,the MA-free quasi-2D ACI perovskites prepared via IPAS deposition have opposite reverse-graded QW distribution and improved vertical orientation,leading to a remarkable PEC of up to 18.86%and allowing the preparation of unpackaged devices with prominent working stability(80%,400 h).The underlying mechanism and crystallization pathway of IPAS deposition confirm that sequential deposition has unique superiority in regulating the QW distribution and crystalline orientation of quasi-2D perovskites. | Shaofu Wang Yumin Liu Junjie Zou Junjun Jin Yun Jiang Tao Zeng Wenyan Zhao Rong-Xiang He Bolei Chen Yu Chen Shuoxue Jin Hong-Xiang Li Zhipeng Xie Chang-An Wang Weiwei Sun Qiang Cao Xing-Zhong Zhao | 2023 | InfoMat2023，5，3： | 0 |
| 11 | Chemical characterization and source apportionment of atmospheric submicron particles on the western coast of Taiwan Strait, China显示文摘Taiwan Strait is a special channel for subtropical East Asian Monsoon and its western coast is an important economic zone in China. In this study, a suburban site in the city of Xiamen on the western coast of Taiwan Strait was selected for fine aerosol study to improve the understanding of air pollution sources in this region. An Aerodyne high-resolution time-of-flight aerosol mass spectrometer(HR-To F-AMS) and an Aethalometer were deployed to measure fine aerosol composition with a time resolution of 5 min from May 1to 18, 2015. The average mass concentration of PM1 was 46.2 ± 26.3 μg/m^3 for the entire campaign. Organics(28.3%), sulfate(24.9%), and nitrate(20.6%) were the major components in the fine particles, followed by ammonium, black carbon(BC), and chloride. Evolution of nitrate concentration and size distribution indicated that local NOx emissions played a key role in high fine particle pollution in Xiamen. In addition, organic nitrate was found to account for 9.0%–13.8% of the total measured nitrate. Positive Matrix Factorization(PMF)conducted with high-resolution organic mass spectra dataset differentiated the organic aerosol into three components, including a hydrocarbon-like organic aerosol(HOA) and two oxygenated organic aerosols(SV-OOA and LV-OOA), which on average accounted for 27.6%,28.8%, and 43.6% of the total organic mass, respectively. The relationship between the mass concentration of submicron particle species and wind further confirmed that all major fine particle species were influenced by both strong local emissions in the southeastern area of Xiamen and regional transport through the Taiwan Strait. | Liming Cao Qiao Zhu Xiaofeng Huang Junjun Deng Jinsheng Chen Youwei Hong Lingling Xu Lingyan He | 2017 | Journal of Environmental Sciences2017，29，2： | 0 |
| 12 | Study on the optimization of transformation systems in watermelon显示文摘To date,the genetic transformation system of watermelon has remained inefficient.In this study,the genetic transformation system of watermelon mediated by Agrobacterium tumefaciens was optimized,including different seedling ages,strains of Agrobacterium tumefaciens,concentrations of acetosyringone infected solution,co-culture time,selection pressure of antibiotics timentin and glufosinate,and concentrations of hormones 6-benzylaminopurine,indoleacetic acid and naphthylacetic acid in the corresponding culture medium.Our results suggested that cotyledons would be used as explants,disinfected with 6%sodium hypochlorite for 12 min,cultured for 3 d,and then infected with Agrobacterium inoculum(Agrobacterium EHA105)containing 200μM acetosyringone and 0.02 of final OD_(600).The explants differentiated into adventitious shoots in the medium with 1.5 mg/L 6-benzylaminopurine and 200μM timentin.Positive adventitious shoots were obtained through further screening by 1.4 mg/L herbicide glufosinate-ammonium,and were induced by 0.1 mg/L naphthalene acetic acid into independent plants.Our system improves the genetic transformation efficiency of watermelon and provides a technical basis for continuous acquisition of watermelon transgenic plants. | Lihong Cao Wei Wei Junjun Shen Zhongmin Xu Zheng Li | 2022 | Vegetable Research2022，2，1： | 0 |
