4Color-tunable ultralong organic phosphorescence materials for visual UV-light detection显示文摘Ultralong organic phosphorescence(UOP)materials have roused considerable attention in the field of photonics and optoelectronics owing to the feature of long-lived emission lifetimes.However,to develop UOP materials with color-tunability is still a formidable challenge.Here,we report a class of UOP materials containing carbonyl,amino or amide groups,exhibiting colortunable persistent luminescence ranging from blue(458 nm)to yellow-green(508 nm)under different UV wavelength excitation.Taken theoretical and experimental results together,we conclude that the excitation dependent color-tunable UOP emission is ascribed to multiple emission centers from single molecular and aggregated states in crystal.Given color-tunable UOP feature,these materials are used to successfully realize visual UV-light detection.This finding not only provides a strategy to design new organic phosphorescent molecules with colorful emission,but also extends the scope of the applications of purely organic phosphorescent materials.Lifang Bian Huili Ma Wenpeng Ye Anqi Lv He Wang Wenyong Jia Long Gu Huifang Shi Zhongfu An Wei Huang 2020Science China Chemistry2020,63,10:3
5Interaction Between Variations in Dopamine D2 and Serotonin 2A Receptor is Associated with Short-Term Response to Antipsychotics in Schizophrenia显示文摘Dear Editor,Schizophrenia is a chronic and debilitating brain disorder,which has a strong genetic component with heritability ranging from 66%to 85%[1,2].Currently,antipsychotic drugs remain the most effective treatment for the psychotic symptoms of schizophrenia[3].Because of the severe sideeffects of first-generation antipsychotics(FGAs),secondgeneration antipsychotics(SGAs)have become more widely used in the treatment of schizophrenia.Liansheng Zhao Huijuan Wang Yamin Zhang Jinxue Wei Peiyan Ni Hongyan Ren Gang Li Qiang Wang Gavin P Reynolds Weihua Yue Wei Deng Hao Yan Liwen Tan Qi Chen Guigang Yang Tianlan Lu Lifang Wang Fuquan Zhang Jianli Yang Keqing Li Luxian Lv Qingrong Tan Yinfei Li Hua Yu Hongyan Zhang Xin Ma Fude Yang Lingjiang Li Chuanyue Wang Huiyao Wang Xiaojing Li Wanjun Guo Xun Hu Yang Tian Xiaohong Ma Jeremy Coid Dai Zhang Chao Chen Tao Li Chinese Antipsychotics Pharmacogenomics Consortium 2019Neuroscience Bulletin2019,35,6:3
6Testing the role of genetic variation of the MC4R gene in Chinese population in antipsychotic-induced metabolic disturbance显示文摘Antipsychotic-induced metabolic disturbance(AIMD) is a common adverse effect of antipsychotics with genetics partly underpinning variation in susceptibility among schizophrenia patients. Melanocortin4 receptor(MC4 R) gene, one of the candidate genes for AIMD, has been under-studied in the Chinese patients. We conducted a pharmacogenetic study in a large cohort of Chinese patients with schizophrenia. In this study, we investigated the genetic variation of MC4 R in Chinese population by genotyping two SNPs(rs489693 and rs17782313) in 1,991 Chinese patients and examined association of these variants with the metabolic effects that were often observed to be related to AIMD. Metabolic measures, including body mass index(BMI), waist circumference(WC), glucose, triglyceride, high-density lipoprotein(HDL), and low-density lipoprotein(LDL) levels were assessed at baseline and after 6-week antipsychotic treatment. We found that interaction of SNP×medication status(drug-na?ve/medicated) was significantly associated with BMI, WC, and HDL change %, respectively. Both SNPs were significantly associated with baseline BMI and WC in the medicated group. Moderate association of rs489693 with WC, Triglyceride, and HDL change % were observed in the whole sample. In the drug-na?ve group, we found recessive effects of rs489693 on BMI gain more than 7%, WC and Triglyceride change %, with AA incurring more metabolic adverse effects. In conclusion, the association between rs489693 and the metabolic measures is ubiquitous but moderate. Rs17782313 is less involved in AIMD. Two SNPs confer risk of AIMD to patients treated with different antipsychotics in a similar way.Yamin Zhang Hongyan Ren Qiang Wang Wei Deng Weihua Yue Hao Yan Liwen Tan Qi Chen Guigang Yang Tianlan Lu Lifang Wang Fuquan Zhang Jianli Yang Keqing Li Luxian Lv Qingrong Tan Hongyan Zhang Xin Ma Fude Yang Lingjiang Li Chuanyue Wang Dai Zhang Liansheng Zhao Huiyao Wang Xiaojing Li Wanjun Guo Xun Hu Yang Tian Xiaohong Ma Tao Li Chinese Antipsychotics Pharmacogenomics Consortium 2019Science China(Life Sciences)2019,62,4:3
7All-in-One Deposition to Synergistically Manipulate Perovskite Growth for High-Performance Solar Cell显示文摘Nonradiative recombination losses originating from crystallographic distortions and issues occurring upon interface formation are detrimental for the photovoltaic performance of perovskite solar cells.Herein,we incorporated a series of carbamide molecules(urea,biuret,or triuret)consisting of both Lewis base(-NH2)and Lewis acid(-C=O)groups into the perovskite precursor to simultaneously eliminate the bulk and interface defects.Depending on the different coordination ability with perovskite component,the incorporated molecules can either modify crystallization dynamics allowing for large crystal growth at low temperature(60℃),associate with antisite or undercoordinated ions for defect passivation,or accumulate at the surface as an energy cascade layer to enhance charge transfer,respectively.Synergistic benefits of the above functions can be obtained by rationally optimizing additive combinations in an all-in-one deposition method.As a result,a champion efficiency of 21.6%with prolonged operational stability was achieved in an inverted MAPbI3 perovskite solar cell by combining biuret and triuret additives.The simplified all-in-one fabrication procedure,adaptable to different types of perovskites in terms of pure MAPbI3,mixed perovskite,and all-inorganic perovskite,provides a cost-efficient and reproducible way to obtain high-performance inverted perovskite solar cells.Yifan Lv Hui Zhang Jinpei Wang Libao Chen Lifang Bian Zhongfu An Zongyao Qian Guoqi Ren Jie Wu Frank Nuesch Wei Huang 2020Research2020,,1:2

10Research on the Seismic Activity of the Lower Yangtze River-South Yellow Sea Seismic Zone显示文摘The Lower Yangtze River-South Yellow Sea Seismic Zone,located at the southeast of the Northern China Seismic Zone, characterized by moderate-strong earthquakes, is an intensive earthquake zone,which is controlled by a series of faults within the Lower Yangtze River-South Yellow Sea Seismic Zone. This article counts and calculates the bvalue,V 4 and energy density value of medium-small earthquakes by taking full advantage of the latest data from regional seismic stations,reviews data of historical earthquakes and seismic structure,and discusses the relationship between spatial distribution of the b-value, historical strong earthquakes and spatial distribution of energy density of medium-small earthquakes,and further investigates the seismic activity of the Lower Yangtze River- South Yellow Sea Seismic Zone. This article obtains seismic activity parameters of the Lower Yangtze River-South Yellow Sea Seismic Zone as calculation parameters for probabilistic seismic hazard analysis,and discusses the trend of this seismic zone in the next one hundred years and deduces the potential seismic hazard region within this seismic zone,which provides references and methods for long-term prediction on seismic activity. The research results are significant to seismic zoning, seismic safety evaluation of engineering sites and long-term prediction of seismic activity.Xie Zhuojuan Lv Yuejun Peng Yanju Lan Jingyan Zhang Lifang 2013Earthquake Research in China2013,27,2:0
11Methods for Estimating Mean Annual Rate of Earthquakes in Moderate and Low Seismicity Regions显示文摘Two kinds of methods for determining seismic parameters are presented,that is,the potential seismic source zoning method and grid-spatially smoothing method. The Gaussian smoothing method and the modified Gaussian smoothing method are described in detail, and a comprehensive analysis of the advantages and disadvantages of these methods is made. Then,we take central China as the study region,and use the Gaussian smoothing method and potential seismic source zoning method to build seismic models to calculate the mean annual seismic rate. Seismic hazard is calculated using the probabilistic seismic hazard analysis method to construct the ground motion acceleration zoning maps. The differences between the maps and these models are discussed and the causes are investigated. The results show that the spatial smoothing method is suitable for estimating the seismic hazard over the moderate and low seismicity regions or the hazard caused by background seismicity; while the potential seismic source zoning method is suitable for estimating the seismic hazard in well-defined seismotectonics. Combining the spatial smoothing method and the potential seismic source zoning method with an integrated account of the seismicity and known seismotectonics is a feasible approach to estimate the seismic hazard in moderate and low seismicity regions.Peng Yanju Zhang Lifang Lv Yuejun Xie Zhuojuan 2012Earthquake Research in China2012,26,3:0
12Analysis on Completeness of Small Earthquake Data in the Northeast Seismic Zone and Its Influence on Seismicity Parameters显示文摘Taking the northeast seismic zone as an example and based on the magnitude-frequency distribution principles of the G-R relationship and the study on the temporal and spatial distribution characteristics of the minimum magnitude of completeness M C in each time interval,this paper makes a statistical analysis on the seismicity parameters of the research area and explores the influence of the completeness of small earthquake data on the seismicity parameters and seismic hazard analysis.It shows that the completeness analysis of the regional small earthquakes data provides a possible means for obtaining more accurate seismicity parameters that can better represent the actual regional seismicity level for areas of low seismicity.The research methods of this article and its conclusion can be used as a reference for the completeness analysis of earthquake data and seismic activity research.Xie Zhuojuan Lv Yuejun Peng Yanju Zhang Lifang 2013Earthquake Research in China2013,27,3:0
13The Method of Spatially Smoothed Seismicity Parameters in Consideration of Seismotectonic Background and Its Application to Seismic Hazard Estimation显示文摘In this study, the North China seismic region was selected as the study area, and evaluation of seismic hazard using the spatial smoothing seismicity model was performed. Firstly, the study area is divided into grids, and some parameters (e.g. b-value, M0, Mu, azimuth and M-L relationship) for each seismotectonic model were assigned. Secondly, using elliptical smoothing based on a seismotectonic background model, the statistical earthquake incidence rate in each grid is successively calculated. Lastly, the relevant ground motion attenuation relationship is chosen to assess seismic hazard of general sites. The maps for the distribution of horizontal peak ground acceleration with 10% probability of exceedance in 50 years were obtained by using the seismic hazard analysis method based on grid source. This seismicity model simplifies the methodology of probabilistic seismic hazard analysis, especially appropriate for those places where seismic tectonics is not yet clearly known. This method can provide valuable references for seismic zonation and seismic safety assessment for significant engineering projects.Zhang Lifang Lv Yuejun Peng Yanju Ma Xiaoling Cui Manfeng 2013Earthquake Research in China2013,27,1:0
