3A Novel Semiconductor CIGS Photovoltaic Material and Thin-Film ED Technology显示文摘In order to achieve low cost high efficiency thin film solar cells,a novel Semiconductor Photovoltaic (PV) active material CuIn 1-x Ga x Se 2 (CIGS) and thin film Electro Deposition (ED) technology is explored.Firstly,the PV materials and technologies is investigated,then the detailed experimental processes of CIGS/Mo/glass structure by using the novel ED technology and the results are reported.These results shows that high quality CIGS polycrystalline thin films can be obtained by the ED method,in which the polycrystalline CIGS is definitely identified by the (112),(204,220) characteristic peaks of the tetragonal structure,the continuous CIGS thin film layers with particle average size of about 2μm of length and around 1 6μm of thickness.The thickness and solar grade quality of CIGS thin films can be produced with good repeatability.Discussion and analysis on the ED technique,CIGS energy band and sodium (Na) impurity properties,were also performed.The alloy CIGS exhibits not only increasing band gap with increasing x ,but also a change in material properties that is relevant to the device operation.The beneficial impurity Na originating from the low cost soda lime glass substrate becomes one prerequisite for high quality CIGS films.These novel material and technology are very useful for low cost high efficiency thin film solar cells and other devices.ZHENG Guang fu 1,YANG Hong xing 1,MAN Cheuk ho 1,WONG Wing lok 2, AN Da wei 1 and John BURNETT 1(1 Centre for Development of Solar Energy Technology,Department of Building Services Engineering, The Hong Kong Polytechnic University,Hong Kong,C 2001Journal of Semiconductors2001,22,11:10

5Involvement of C2H2 zinc finger proteins in the regulation of epidermal cell fate determination in Arabidopsis显示文摘Cell fate determination is a basic developmental process during the growth of multicellular organisms.Trichomes and root hairs of Arabidopsis are both readily accessible structures originating from the epidermal cells of the aerial tissues and roots respectively, and they serve as excellent models for understanding the molecular mechanisms controlling cell fate determination and cell morphogenesis. The regulation of trichome and root hair formationis a complex program that consists of the integration of hormonal signals with a large number of transcriptional factors, including MYB and b HLH transcriptional factors.Studies during recent years have uncovered an important role of C2H2 type zinc finger proteins in the regulation of epidermal cell fate determination. Here in this minireview we briefly summarize the involvement of C2H2 zinc finger proteins in the control of trichome and root hair formation in Arabidopsis.An Yan Minjie Wu Yongqin Zhao Aidong Zhang Bohan Liu John Schiefelbein Yinbo Gan 2014Journal of Integrative Plant Biology2014,56,12:7
6A fundamental theorem for eco-environmental surface modelling and its applications显示文摘We propose a fundamental theorem for eco-environmental surface modelling(FTEEM) in order to apply it into the fields of ecology and environmental science more easily after the fundamental theorem for Earth’s surface system modeling(FTESM). The Beijing-Tianjin-Hebei(BTH) region is taken as a case area to conduct empirical studies of algorithms for spatial upscaling, spatial downscaling, spatial interpolation, data fusion and model-data assimilation, which are based on high accuracy surface modelling(HASM), corresponding with corollaries of FTEEM. The case studies demonstrate how eco-environmental surface modelling is substantially improved when both extrinsic and intrinsic information are used along with an appropriate method of HASM. Compared with classic algorithms, the HASM-based algorithm for spatial upscaling reduced the root-meansquare error of the BTH elevation surface by 9 m. The HASM-based algorithm for spatial downscaling reduced the relative error of future scenarios of annual mean temperature by 16%. The HASM-based algorithm for spatial interpolation reduced the relative error of change trend of annual mean precipitation by 0.2%. The HASM-based algorithm for data fusion reduced the relative error of change trend of annual mean temperature by 70%. The HASM-based algorithm for model-data assimilation reduced the relative error of carbon stocks by 40%. We propose five theoretical challenges and three application problems of HASM that need to be addressed to improve FTEEM.Tianxiang YUE Na ZHAO Yu LIU Yifu WANG Bin ZHANG Zhengping DU Zemeng FAN Wenjiao SHI Chuanfa CHEN Mingwei ZHAO Dunjiang SONG Shihai WANG Yinjun SONG Changqing YAN Qiquan LI Xiaofang SUN Lili ZHANG Yongzhong TIAN Wei WANG Ying’an WANG Shengnan MA Hongsheng HUANG Yimin LU Qing WANG Chenliang WANG Yuzhu WANG Ming LU Wei ZHOU Yi LIU Xiaozhe YIN Zong WANG Zhengyi BAO Miaomiao ZHAO Yapeng ZHAO Yimeng JIAO Ufra NASEER Bin FAN Saibo LI Yang YANG John PWILSON 2020Science China Earth Sciences2020,63,8:7
7Thunderclap Headache Caused by an Inadvertent Epidural Puncture During Oxygen-ozone Therapy for Patient with Cervical Disc Herniation显示文摘To the Editor: A 54-year-old woman with no significant history of a headache or hypertension underwent epidural oxygen-ozone injection at a concentration of 30 μg/ml (3 ml) for cervical disc herniation at cervical vertebra (C6-C7) level.Throughout the procedure, the routine monitorings of blood pressure, heart rate, and blood oxygen saturation were performed.One minute following the end of the injection, the patient developed a high-intensity headache mimicking symptoms of a ruptured cerebral aneurysm.Hui Liu Yong Wang Jian-Xiong An John P Williams Doris K Cope 2016Chinese Medical Journal2016,,4:7
8Evaluation and SAR analysis of the cytotoxicity of tanshinones in colon cancer cells显示文摘AIM:This study was designed to evaluate the anti-cancer actions of tanshinone I and tanshinone IIA,and six derivatives of tanshinone IIA on normal and cancerous colon cells.Structure activity relationship(SAR) analysis was conducted to delineate the significance of the structural modifications of tanshinones for improved anti-cancer action.METHOD:Tanshinone derivatives were designed and synthesized according to the literature.The cytotoxicity of different compounds on colon cancer cells was determined by the MTT assay.Apoptotic activity of the tanshinones was measured by flow cytometry(FCM).RESULTS:Tanshinone I and tanshinone IIA both exhibited significant cytotoxicity on colon cancer cells.They are more effective in p53+/+ colon cancer cell line.It was also noted that the anti-cancer activity of tanshinone I was more potent and selective.Two of the derivatives of tanshinone IIA(N1 and N2) also exhibited cytotoxicity on colon cancer cells.CONCLUSIONS:The anti-colon cancer activity of tanshinone I was more potent and selective than tanshinone IIA,and is p53 dependent.The derivatives obtained by structural modifications of tanshinone IIA exhibited lower cytotoxicity on both normal and colon cancer cells.From steric and electronic characteristics point of view,it was concluded that structural modifications of ring A and furan or dihydrofuran ring D on the basic structure of tanshinones influences the activity.An increase of the delocalization of the A and B rings could enhance the cytotoxicity of such compounds,while a non-planar and small sized D ring region would provide improved anti-cancer activity.WANG Lin LIU An ZHANG Fei-Long Yeung John H.K.

11Three Cases of Idiopathic Superior Laryngeal Neuralgia Treated by Superior Laryngeal Nerve Block under Ultrasound Guidance显示文摘In treating superior laryngeal neuralgia (SLN),superior laryngeal nerve blocks (SLNBs) can provide immediate relief of persistent pain.Although SLNB was effective,the procedure can increase the risks due to the proximity to the carotid artery,external vein,and other vessels.To avoid complications such as advertent intravascular injection,local anesthetic toxicity from intravascular absorption,and intratracheal injection,we successfully blocked the superior laryngeal nerve under ultrasound guidance in three patients suffering from SLN.The written informed consent before treatment was obtained for each patient participating in this study.Jian-Ping Wu Flui Liu Jian-Xiong An Doris K Cope John P Williams 2016Chinese Medical Journal2016,,16:3
