| 1 | Exploitation of Bi2O2Se/graphene van der Waals heterojunction for creating efficient photodetectors and short-channel field-effect transistors显示文摘The formation of heterojunction within solid-state devices enables them with eventually high performances,but provides a challenge for material synthesis and device fabrication because strict conditions such as lattice match are needed.Herein,we show a facile method to fabricate a van der Waals(vdW)heterojunction between two-dimensional(2D)bismuth oxyselenide(Bi2O2Se)and graphene,during which the graphene is directly transferred to the Bi2O2Se and served as a lowcontract-resistant electrode with small work function mismatch(~50 meV).As an optoelectronic device,the Bi2O2Se/graphene vdW heterojunction allows for the efficient sensing toward 1200-nm incident laser.Regarding the application of fieldeffect transistors(FETs),the short-channel(50 nm)sample can be synthesized by utilizing these two 2D materials(ie,channel:Bi2O2Se;drain/source terminal:graphene)and the n-type characteristic can be observed with the accordant field modulation.It is confirmed that we show a simple way to prepare the vdW heterojunction which is aiming to the high-performance applications among optoelectronics and FETs. | Congwei Tan Shipu Xu Zhenjun Tan Luzhao Sun Jinxiong Wu Tianran Li Hailin Peng | 2019 | InfoMat2019，1，3： | 8 |
| 2 | The heterogeneity of islet autoantibodies and the progression of islet failure in type 1 diabetic patients显示文摘Type 1 diabetes mellitus is heterogeneous in many facets. The patients suffered from type 1 diabetes present several levels of islet function as well as variable number and type of islet-specific autoantibodies. This study was to investigate prevalence and heterogeneity of the islet autoantibodies and clinical phenotypes of type 1 diabetes mellitus; and also discussed the process of islet failure and its risk factors in Chinese type 1 diabetic patients. A total of 1,291 type 1 diabetic patients were enrolled in this study. Demographic information was collected. Laboratory tests including mixed-meal tolerance test, human leukocyte antigen alleles, hemoglobin A1 c, lipids, thyroid function and islet autoantibodies were conducted. The frequency of islet-specific autoantibody in newly diagnosed T1 DM patients(duration shorter than half year) was 73% in East China. According to binary logistic regressions, autoantibody positivity, longer duration and lower Body Mass Index were the risk factors of islet failure. As the disease developed, autoantibodies against glutamic acid decarboxylase declined as well as the other two autoantibodies against zinc transporter 8 and islet antigen 2. The decrease of autoantibodies was positively correlated with aggressive beta cell destruction. Autoantibodies can facilitate the identification of classic T1 DM from other subtypes and predict the progression of islet failure. As there were obvious heterogeneity in autoantibodies and clinical manifestation in different phenotypes of the disease, we should take more factors into consideration when identifying type 1 diabetes mellitus. | Jin Liu Lingling Bian Li Ji Yang Chen Heng Chen Yong Gu Bingqin Ma Wei Gu Xinyu Xu Yun Shi Jian Wang Dalong Zhu Zilin Sun Jianhua Ma Hui Jin Xing Shi Heng Miao Bing Xin Yan Zhu Zhenwen Zhang Ruifang Bu Lan Xu Guangde Shi Wei Tang Wei Li Dongmei Zhou Jun Liang Xingbo Cheng Bimin Shi Jixiang Dong Ji Hu Chen Fang Shao Zhong Weinan Yu Weiping Lu Chenguang Wu Li Qian Jiancheng Yu Jialin Gao Xiaoqiang Fei Qingqing Zhang Xueqin Wang Shiwei Cui Jinluo Cheng Ning Xu Guofeng Wang Guoqing Han Chunrong Xu Yun Xie Minmin An Wei Zhang Zhixiao Wang Yun Cai Qi Fu Yu Fu Shuai Zheng Fan Yang Qingfang Hu Hao Dai Yu Jin Zheng Zhang Kuanfeng Xu Yifan Li Jie Shen Hongwen Zhou Wei He Xuqin Zheng Xiao Han Liping Yu Jinxiong She Mei Zhang Tao Yang | 2016 | Science China(Life Sciences)2016，59，9： | 5 |

| 4 | Bn.YCO affects chloroplast development in Brassica napus L.显示文摘Mature chloroplasts,as the main sites of photosynthesis,are essential for seedling growth in higher plants.Loss of function of genes involved in chloroplast development changes plant phenotype.We obtained a YELLOW COTYLEDON (YCO) mutant in rapeseed (Brassica napus L.) using CRISPR-Cas9.Bn.YCO,a gene of unknown function,has two homologous copies (Bna A01.YCO and Bna C01.YCO) in B.napus.Homozygous mutation of these two homologs resulted in yellow cotyledons and chlorotic true leaves.Transmission electron microscopy revealed that the formation of thylakoid membranes was inhibited in yellow cotyledons.Sequence similarity search revealed that YCO was conserved in different species,and a subcellular location assay verified that Bn.YCO was located in the chloroplast.Bn.YCO was expressed in multiple tissues,most highly in cotyledons.Knockout of Bn.YCO blocked the transcription of plastid genes,especially those of photosystem genes transcribed by plastid-encoded polymerase.Transcriptome sequencing showed that the majority of genes involved in ribosome assembly and photosynthesis were down-regulated in Bn.yco mutants.These results suggested that loss of function of Bn.YCO affected plastid gene transcription,which influenced chloroplast biogenesis in rapeseed seedlings. | Tingting Liu Baolong Tao Hanfei Wu Jing Wen Bin Yi Chaozhi Ma Jinxing Tu Tingdong Fu Lixia Zhu Jinxiong Shen | 2021 | The Crop Journal2021，9，5： | 1 |

| 6 | Homogeneous large deformation analysis of a dielectric elastomer peristaltic actuator显示文摘A series of isometric,radially expanding tubular units,made of dielectric elastomer with compliant electrodes,constitute a soft linear peristaltic pump with distributed actuation for transport of incompressible fluids.Based on the Gent strain energy model,this paper theoretically analyzes the homogeneous large deformation of the peristaltic unit.We discuss the effects of axial prestretch on the actuation of the actuator.We then predict the maximum actuation strain of this actuator which is limited by dielectric strength of the polymer.The results presented here extend the previous study based on linear elasticity,and can predict the electromechanical behaviors of the novel actuator at large deformations. | WU XiaoHong SUN WenJie LI Bo CHEN HuaLing ZHOU JinXiong | 2012 | Science China(Technological Sciences)2012，55，2： | 0 |
| 7 | Temperature-driven reversible structural transformation and conductivity switching in ultrathin Cu_(9)S_(5)crystals显示文摘Two-dimensional(2D)materials with reversible phase transformation are appealing for their rich physics and potential applications in information storage.However,up to now,reversible phase transitions in 2D materials that can be driven by facile nondestructive methods,such as temperature,are still rare.Here,we introduce ultrathin Cu_(9)S_(5)crystals grown by chemical vapor deposition(CVD)as an exemplary case.For the first time,their basic electrical properties were investigated based on Hall measurements,showing a record high hole carrier density of~1022 cm^(-3) among 2D semiconductors.Besides,an unusual and repeatable conductivity switching behavior at~250 K were readily observed in a wide thickness range of CVD-grown Cu_(9)S_(5)(down to 2 unit-cells).Confirmed by in-situ selected area electron diffraction,this unusual behavior can be ascribed to the reversible structural phase transition between the room-temperature hexagonalβphase and low-temperatureβ’phase with a superstructure.Our work provides new insights to understand the physical properties of ultrathin Cu_(9)S_(5)crystals,and brings new blood to the 2D materials family with reversible phase transitions. | Lei Zhang Zeya Li Ying Deng Li Li Zhansheng Gao Jiabiao Chen Zhengyang Zhou Junwei Huang Weigao Xu Xuewen Fu Hongtao Yuan Feng Luo Jinxiong Wu | 2023 | Nano Research2023，16，7： | 0 |
| 8 | Near room-temperature ferromagnetism in air-stable twodimensional Cr_(1−x)Te grown by chemical vapor deposition显示文摘Identifying air-stable two-dimensional(2D)ferromagnetism with high Curie temperature(T_(c))is highly desirable for its potential applications in next-generation spintronics.However,most of the work reported so far mainly focuses on promoting one specific key factor of 2D ferromagnetism(T_(c)or air stability),rather than comprehensive promotion of both of them.Herein,ultrathin Cr_(1-x)Te crystals grown by chemical vapor deposition(CVD)show thickness-dependent T_(c)up to 285 K.The out-of-plane ferromagnetic order is well preserved down to atomically thin limit(2.0 nm),as evidenced by anomalous Hall effect observed in non-encapsulated samples.Besides,the CVD-grown Cr_(1-x)Te nanosheets present excellent ambient stability,with no apparent change in surface roughness or electrical transport properties after exposure to air for months.Our work provides an alternative platform for investigation of intrinsic 2D ferromagnetism and development of innovative spintronic devices. | Zhansheng Gao Ming Tang Junwei Huang Jiabiao Chen Wei Ai Linglu Wu Xinyue Dong Yifei Ma Zheshan Zhang Lei Zhang Yaping Du Huixia Fu Hongtao Yuan Jinxiong Wu Feng Luo | 2022 | Nano Research2022，15，4： | 0 |
| 9 | Development of a multi-view and geo-event-driven real-time collaborative GIS显示文摘Supporting distributed real-time collaborative work has become an important development trend in GIS.It enables group users to cooperate and improve the use of scientific data and collaboration technologies.Real-time collaborative GIS(RCGIS)provides a platform for supporting synchronous collaboration using geospatial data in various forms.Traditional RCGIS generally works on a single map view,which has the disadvantage of collaborative interface confusion.The traditional system-driven mechanism of RCGIS is a computer-interaction event that has the disadvantage of an unfriendly collaborative perception.This paper presents a design and prototype of a RCGIS based on multi-view and geo-event driven mechanisms.The geo-event-driven mechanism provides users with a smoother collaborative perception and interactions that are more natural and friendly.The collaboration process for a GIS that is driven by geo-events is also discussed.A multi-view technique is used to make real-time GIS collaboration more orderly.The paper also proposes a synchronization strategy for public–private views.Finally,walk-through examples are used to demonstrate the use of RCGIS within a web environment. | Sun Yaqin Xu Chen Wu Jinxiong Yuan Hang Shi Haibo Zhan Xiumei Zhang Lin | 2022 | International Journal of Digital Earth2022，15，1： | 0 |
