| 1 | Psychological impact of the COVID-19 pandemic on healthcare workers:a cross-sectional study in China显示文摘Background Healthcare workers fighting against the coronavirus disease 2019(COVID-19)pandemic are under tremendous pressure,which puts them at an increased risk of developing psychological problems.Aims This study aimed to investigate the prevalence of psychological problems in different healthcare workers(ie,physicians,medical residents,nurses,technicians and public health professionals)during the COVID-19 pandemic in China and explore factors that are associated with the onset of psychological problems in this population during this public health crisis.Methods A cross-sectional,web-based survey was conducted in February 2020 among healthcare workers during the COVID-19 pandemic.Psychological problems were assessed using the Generalized Anxiety Disorder Scale,Patient Health Questionnaire and Insomnia Severity Index.Logistic regression analyses were used to explore the factors that were associated with psychological problems.Results The prevalence of symptoms of anxiety,depression,insomnia and the overall psychological problems in healthcare workers during the COVID-19 pandemic in China was 46.04%,44.37%,28.75%and 56.59%,respectively.The prevalence of the overall psychological problems in physicians,medical residents,nurses,technicians and public health professionals was 60.35%,50.82%,62.02%,57.54%and 62.40%,respectively.Compared with healthcare workers who did not participate in front-line work,front-line healthcare workers had a higher risk of anxiety,insomnia and overall psychological problems.In addition,attention to negative or neutral information about the pandemic,receiving negative feedback from families and friends who joined front-line work,and unwillingness to join front-line work if given a free choice were three major factors for these psychological problems.Conclusions Psychological problems are pervasive among healthcare workers during the COVID-19 pandemic.Receiving negative information and participating in front-line work appear to be.important risk factors for psychological problems.The psychological health of different healthcare workers should be protected during the COVID-19 pandemic with timely interventions and proper information feedback. | Jianyu Que Le Shi Jiahui Deng Jiajia Liu Li Zhang Suying Wu Yimiao Gong Weizhen Huang Kai Yuan Wei Yan Yankun Sun Maosheng Ran Yanping Bao Lin Lu | 2020 | General Psychiatry2020，33，3： | 8 |
| 2 | Optically stimulated luminescence dosimeter based on CaS:Eu,Sm显示文摘Alkaline earth sulfides (MgS,CaS and BaS) crystal doped with rare-earth ions is an optically stimulated luminescence dosimeter with very high sensitivity,short time constant of the optically stimulated luminescence (OSL) separated perfectly from the stimulation.In this paper,an OSL dosimeter is described.It has linear dose response from 0.01 to 1000 Gy.The equipment,relatively simple and small in size is promising for applications in space exploration and for high dose irradiation and dangerous irradiation conditions. | LIU Yanping CHEN Zhaoyang BA Weizhen FAN Yanwei GUO Qi YU Xuefeng CHANG Aiming LU Wu DU Yanzhao | 2008 | Nuclear Science and Techniques2008，19，2： | 4 |
| 3 | One-pot synthesis of 2,5-bis(hydroxymethyl)furan from biomass derived 5-(chloromethyl)furfural in high yield显示文摘5-(Chloromethyl)furfural(CMF),as a new platform molecular,has become a hot topic in the field of biorefinery.Herein,the one-pot conversion of CMF to 2,5-bis(hydroxymethyl)furan(BHMF)in the water phase was demonstrated for the first time.A 91%BHMF yield was obtained over Ru/Cu Oxcatalyst,and BHMF was mainly produced by the consecutive hydrolysis and hydrogenation of CMF with 5-hydroxymethylfurfural(HMF)as an intermediate.Kinetic studies revealed that the conversion of HMF to BHMF was the rate-determining step.Remarkably,the characterizations and density functional theory(DFT)calculations further revealed the lower electron density of Ru NPs in Ru/Cu Oxcatalyst,resulting in a larger adsorption energy and a smaller free energy difference for the formation of alcohols.The present findings offered a new pathway for biomass-derived diol production through CMF as a potential source. | Binglin Chen Yunchao Feng Sen Ma Weizhen Xie Guihua Yan Zheng Li Jonathan Sperry Shuliang Yang Xing Tang Yong Sun Lu Lin Xianhai Zeng | 2023 | Journal of Energy Chemistry2023，，1： | 1 |

| 8 | Base-free oxidative esterification of 5-hydroxymethylfurfural to furan-2,5-dimethylcarboxylate over n-doped carbon-supported Co/Fe bimetallic catalyst under batch-operation or continuous-flow conditions显示文摘Developing an efficient and easily available catalyst for the selective conversion of biomass-derived 5-hydroxymethylfurfural(HMF)into furan-2,5-dimethylcarboxylate(FDMC),a valuable biomass-based monomer,remains a high demand but formidable challenge.Herein,a facile strategy for the synthesis of N-doped carbon-supported Co/Fe bimetallic catalyst(CoFe-NC)was developed,which provided an outstanding FDMC yield of 93%in a batch reactor(base-free,80℃,2 bar O_(2),4 h).Interestingly,CoFe-NC also gave a high FDMC yield of 91%under continuous-flow conditions for 80 h(5 bar O_(2),80℃,GHSV 1320 h^(-1),LHSV 0.6 h^(-1),base-free).Notably,it is the first time that a non-noble catalyst gave such a high FDMC yield under continuous-flow conditions.The introduction of Fe could greatly improve both the electron intensity of Co-N_(x)species and basicity of the catalyst,which endowed CoFe-NC with improved O_(2)activation capacity and enhanced dehydrogenation activity for the oxidation-esterification of HMF.This work delineates the efficient strategy on the construction of N-doped carbon-supported non-noble catalyst,which might open a new avenue for developing highly efficient catalyst for FDMC production. | Weizhen Xie Binglin Chen Wenlong Jia Huai Liu Zheng Li Shuliang Yang Xing Tang Xianhai Zeng Yong Sun Xixian Ke Tianyuan Li Huayu Fang Lu Lin | 2022 | Journal of Energy Chemistry2022，，12： | 1 |
