| 1 | Controlled growth and photoconductive properties of hexagonal SnS2 nanoflakes with mesa-shaped atomic steps显示文摘We demonstrated the controlled growth of two-dimensional (2D) hexagonal tin disulfide (SnS2) nanoflakes with stacked monolayer atomic steps. The morphology was similar to flat-topped and step-sided mesa plateaus or step pyramids. The SnS2 nanoflakes were grown on mica substrates via an atmospheric-pressure chemical vapor deposition process using tin monosulfide and sulfur powder as precursors. Atomic force microscopy (AFM), electron microscopy, and Raman characterizations were performed to investigate the structural features, and a sequential layer-wise epitaxial growth mechanism was revealed. In addition, systematic Raman characterizations were performed on individual SnS2 nanoflakes with a wide range of thicknesses (1-100 nm), indicating that the A1g peak intensity and Raman shifts were closely related to the thickness of the SnS2 nanoflakes. Moreover, photoconductive AFM was performed on the monolayer-stepped SnS2 nanoflakes, revealing that the flat surface and the edges of the SnS2 atomic steps had different electrical conductive properties and photoconductive behaviors. This is ascribed to the dangling bonds and defects at the atomic step edges, which caused a height difference of the Schottky barriers formed at the interfaces between the PtIr-coated AFM tip and the step edges or the flat surface of the SnS2 nanoflakes. The 2D SnS2 crystals with regular monolayer atomic steps and fast photoresponsivity are promising for novel applications in photodetectors and integrated optoelectronic circuits. | Yi Hu Tao Chen Xiaoqi Wang Lianbo Ma Renpeng Chen Hongfei Zhu Xin Yuan Changzeng Yan Guoyin Zhu Hongling Lv Jia Liang Zhong Jin Jie Liu | 2017 | Nano Research2017，10，4： | 5 |
| 2 | Identification of Ubiquitinated Proteins from Human Multiple Myeloma U266 Cells by Proteomics显示文摘Objective To identify ubiquitinated proteins from complex human multiple myeloma (MM) U266 cells,a malignant disorder of differentiated human B cells.Methods Employing a globally proteomic strategy combining of immunoprecipitation,LC-MS/MS and SCX-LC-MS analysis to identified ubiquitination sites,which were identified by detecting signature peptides containing a GG-tag (114.1 Da) and an LRGG-tag (383.2 Da).Results In total,52 ubiquitinated proteins containing 73 ubiquitination sites of which 14 and 59 sites contained LRGG-tag and GG-tag were identified,respectively.Conclusion Classification analysis by of the proteins identified in the study based on the PANTHER showed that they were associated with multiple functional groups.This suggested the involvement of many endogenous proteins in the ubiquitination in MM. | JIA HongLing LIU ChaoWu GE Feng XIAO ChuanLe LU ChunHua WANG Tong HE QingYu | 2011 | Biomedical and Environmental Sciences2011，24，4： | 2 |
| 3 | Identification and validation of predictive factors for progression to severe COVID-19 pneumonia by proteomics显示文摘Dear Editor,Recent study showed that around 80%of coronavirus disease-19(COVID-19)patients are moderate cases who will recover with or without conventional treatment,while the remaining 20%developed severe disease requiring intensive care.1 Early and accurate screening of new COVID-19 patients to identify those who will develop severe disease will facilitate decision-making on appropriate treatment regimens and reasonable allocation of limited healthcare resources.Therefore,novel predictive factors for disease progress from moderate to severe are urgently needed. | Biao Di Hongling Jia Oscar Junhong Luo Fangqin Lin Kuibiao Li Yuanliang Zhang Huadong Wang Huiying Liang Jun Fan Zhicong Yang | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 0 |

| 5 | Pulmonary Vein Stenosis:A Review显示文摘Pulmonary vein stenosis(PVS)is an extremely rare and lethal disease caused by multiple etiologies.PVS has a bimodal distribution in the population,affecting children and adults.Congenital PVS is the usual PVS type in children,which sometimes develops after cardiothoracic surgery.Acquired PVS,in turn,is the most common PVS type in adults.A review of the relevant literature has shown that PVS after radiofrequency ablation of atrial fibrillation is the most common,as well as that caused by compression of proliferative fibrous tissues or tumor in the mediastinum(eg,PVS caused by fibrosing mediastinitis,lung tumors,metastases,etc).This article provides a comprehensive review of PVS in terms of embryology and anatomy,etiology and triggers,classification,clinical symptoms and signs,treatment,and prognosis,intending to promote the understanding and treatment of this disease. | Mengfei Jia Juan Wang Kaiyu Jiang Hongling Su Yu Li Zhaoxia Guo Hai Zhu Aqian Wang Xin Pan Yunshan Cao | 2023 | Cardiology Discovery2023，3，2： | 0 |
