1Tert-butylhydroquinone-decorated graphene nanosheets and their enhanced capacitive behaviors显示文摘In the present work,tert-butylhydroquinone(TBHQ) was used to decorate graphene nanosheets to obtain a novel and environmentally friendly electrode material for supercapacitors.The fast redox reactions between hydroquinone and quinone generate pseudocapacitance.Graphene layers which have adsorbed TBHQ interact with each other to construct a three-dimensional network.Through this network,electrolyte ions can easily access the surface of graphene to generate electric double-layer capacitance.Electrochemical measurements have shown that using TBHQ as a redox modifier of graphene can obtain a maximum value of 302 F g-1 and provide a 51% enhancement in specific capacitance.Furthermore,excellent rate capability and cycling ability are achieved using the TBHQ-decorated graphene nanosheet electrode.WANG HuanWen WU HongYing CHANG YanQin CHEN YanLi HU ZhongAi 2011Chinese Science Bulletin2011,56,20:9
2Hierarchical Ni_(3)S_(4)@MoS_(2)nanocomposites as efficient electrocatalysts for hydrogen evolution reaction显示文摘Hydrogen evolution reaction(HER)through water splitting is a promising way to solve the energy shortage.Noble-metal-free HER electrocatalysts with high efficiency is very important for practical applications.Herein,we prepare the Ni_(3)S_(4)@MoS_(2)electrocatalyst on carbon cloth(CC)through a two-step hydrothermal process.The Ni_(3)S_(4)nanorods are uniformly integrated with the MoS_(2)nanosheets,forming a hierarchical structure and heterogeneous interfaces.The fast electron transfer on the interface enhances the kinetics of catalytic reaction.The hierarchical structure provides more exposed active sites.The Ni_(3)S_(4)@MoS_(2)/CC exhibits good catalytic activity and long-term stability for HER.This work provided a practicable strategy to develop efficient electrocatalysts for HER in alkaline media.Yuxi Ren Shengli Zhu Yanqin Liang Zhaoyang Li Shuilin Wu Chuntao Chang Shuiyuan Luo Zhenduo Cui 2021Journal of Materials Science & Technology2021,,36:3

6Thoracic Endovascular Aortic Repair for Type B Aortic Dissection显示文摘The incidence of aortic dissection(AD)is estimated to be 1 in 100,000 per year.The onset and progression of AD are rapid.Failure to receive appropriate treatment might lead to death in a short time.Even following active treatment,patients might develop low cardiac output syndrome,severe infection,and hemorrhage,which lead to death.Interventional therapy is a surgical method that has been widely used in Stanford type B AD recently.It is characterized by minimal invasiveness,low incidence of postoperative complications,and low cost.This article will review the interventional treatments for AD and will guide the selection of treatment options.Yanqin Ruan Haofei Li Chang Liu 2022Journal of Advances in Medicine Science2022,5,2:1
7Self-supporting amorphous nanoporous NiFeCoP electrocatalyst for efficient overall water splitting显示文摘The design of cost-effective and earth-abundant bifunctional electrocatalysts for highly efficient oxygen evolution reaction(OER)and hydrogen evolution reaction(HER)is important for water splitting as an advanced renewable energy transformation system.In this work,the self-supporting amorphous Ni Fe Co P catalyst with nanoporous structure via a facile electrochemical dealloying method is reported.Benefiting from the bicontinuous nanostructure,disordered atomic arrangement,abundant active sites and synergic effect of various transition metals,the as-prepared nanoporous NiFeCoP(np-NiFeCoP)catalyst exhibits good electrocatalytic activity,which achieves the current densities of 10 mA cm^(-2) at low overpotentials of 244 mV and 105 mV for OER and HER in 1.0 M KOH,respectively.In addition,the bifunctional electrocatalyst also shows outstanding and durable electrocatalytic activity in water splitting with a small voltage of 1.62 V to drive a current density of 10 mA cm^(-2) in a two-electrode electrolyzer system.The present work would provide a feasible strategy to explore the efficient and low-cost bifunctional electrocatalysts toward overall water splitting.Yao Pang Wence Xu Shengli Zhu Zhenduo Cui Yanqin Liang Zhaoyang Li Shuilin Wu Chuntao Chang Shuiyuan Luo 2021Journal of Materials Science & Technology2021,,23:1
8Two pseudo-polymorphic porous POM-pillared MOFs for sulfide-sulfoxide transformation: Efficient synergistic effects of POM precursors, metal sites and microstructures显示文摘Developing sustainable and powerful heterogeneous catalytic systems to convert sulfides into high-value sulfoxide products has become a particularly appealing field and an arduous challenge.In this work,two porous polyoxometalate-pillared metal-organic frameworks,formulated as H_(3n)[Cu_(3)(pidc)_(2)(H_(2)O)_(2.5)]_(2)[PW_(12)O_(40)]_n·x H_(2)O (n=1.5,x=6 for 1,n=1,x=12 for 2;and H_(3)pidc=2-(3-pyridinyl)-1H-imidazole-4,5-dicarboxylic acid),were consciously manufacture and employed for heterogeneously catalyzed sulfide-sulfoxide transformation.Structural analysis shows that 1 and 2 exhibit similar porous frameworks with nearly identical two-dimensional metal-organic layers further pillared by tetradentate POM ligands with different coordination modes,which also result in the porosity of 1 being almost twice that of 2.In catalyzing the conversion of methyl phenyl sulfide (MPS) to methyl phenyl sulfoxide (MPSO),1 can convert nearly 100%of MPS into MPSO within 30 min,while 2 achieved the similar results requires 50 min.The higher activity of 1 may be attributed to its larger channel that can provide more active sites and more efficient mass transfer process.Systematic structure-activity analyses and mechanistic studies revealed dual-reaction pathways driven by POM sites and metal sites assisted by the structural microenvironment.Yanhong Chen Haiyan An Shenzhen Chang Yanqin Li Tieqi Xu Qingshan Zhu Huiyun Luo Yaohui Huang Yuting Wei 2023Chinese Chemical Letters2023,34,7:0

10Genome-wide analyses of nonsyndromic cleft lip with or without palate identify 20 new risk loci in the Chinese Han population显示文摘Orofacial clefts(OFCs),particularly cleft lip with or without cleft palate(CL/P)and cleft palate only(CPO),are among the most common birth defects in humans(Mossey et al.,2009;Dixon et al.,2011).The birth prevalence rate of OFCs in China is reported to be as high as 1.66 per thousand newborns.Bao Li Liang Yong Yafen Yu Yanqin Yu Qi Zhen Huiyao Ge Yiwen Mao Weiwei Chen Yanxia Yu Yirui Wang Zhuo Li Wencheng Fan Chang Zhang Xia Hu Ruixue Zhang Lu Cao Hao Liu Zhuan Bian Miao He Liangdan Sun 2022Journal of Genetics and Genomics2022,49,9:0
11A Pattern Recognition Framework for Detecting Changes in Chinese Internet Management System显示文摘Past studies on the Chinese internet management system have revealed a smart internet management system that takes advantage of time to filter content with collective action potential.How and why such a system was institutionalized?We offer a historical institutional analysis to explain the way in which the system evolved.We implement social network analysis to examine the Weibo posts of recurrent events,the elections in Area A in 2016 and 2018,to identify pattern changes in the system.There are two aspects of the changes:the centralization of the command line to a single authority and the implementation of a discriminatory strategy to deal with the various online expressions together forming this intelligent system.The improved Chinese information surveillance system demonstrates both a top-down information management and a bottom-up opinion formation.Yu-Sung Su Yanqin Ruan Siyu Sun Yu-tzung Chang 2020Journal of Social Computing2020,1,1:0
