| 1 | Shining light on transition metal sulfides:New choices as highly efficient antibacterial agents显示文摘Globally,millions of people die of microbial infection-related diseases every year.The more terrible situation is that due to the overuse of antibiotics,especially in developing countries,people are struggling to fight with the bacteria variation.The emergence of super-bacteria will be an intractable environmental and health hazard in the future unless novel bactericidal weapons are mounted.Consequently,it is critical to develop viable antibacterial approaches to sustain the prosperous development of human society.Recent researches indicate that transition metal sulfides(TMSs)represent prominent bactericidal application potential owing to the meritorious antibacterial performance,acceptable biocompatibility,high solar energy utilization efficiency,and excellent photo-to-thermal conversion characteristics,and thus,a comprehensive review on the recent advances in this area would be beneficial for the future development.In this review article,we start with the antibacterial mechanisms of TMSs to provide a preliminary understanding.Thereafter,the state-of-the-art research progresses on the strategies for TMSs materials engineering so as to promote their antibacterial properties are systematically surveyed and summarized,followed by a summary of the practical application scenarios of TMSs-based antibacterial platforms.Finally,based on the thorough survey and analysis,we emphasize the challenges and future development trends in this area. | Hecheng Han Jingjing Yang Xiaoyan Li Yuan Qi Zhengyi Yang Zejun Han Yanyan Jiang Martina Stenzel Hui Li Yixin Yin Yi Du Jiurong Liu Fenglong Wang | 2021 | Nano Research2021，14，8： | 2 |
| 2 | Chinese Antarctic Magnetometer Chain at the Cusp Latitude显示文摘A Chinese Antarctic Magnetometer(CAM) chain from Zhongshan Station(ZHS) to Dome-A(DMA) has been established since February 2009.A regular magnetometer is operated at ZHS,and four low power magnetometers are operated along the interior route from ZHS to DMA in the cusp latitude,extending over a distance of 1260 km.These stations fill an important void in the Antarctic magnetometer network.Furthermore,the CAM chain is magnetically conjugated with the Arctic region reaching from the Svalbard archipelago to Daneborg,on the east coast of Greenland.Conjugate measurements using the Arctic and Antarctic magnetometers provide excellent opportunities to investigate phenomena related to the coupling of the solar wind to the magnetosphere and ionosphere,such as magnetic impulse events,flux transfer events,traveling convection vortices and ultra-low frequency waves. | LIU Yonghua HU Hongqiao YANG Huigen ZHANG Beichen SUN Bo WEI Fuhai LIU Yang LIU Jianjun WANG Rui CHEN Zhuotian HU Zejun HAN Desheng SHI Guitao HU Zhengyi WANG Tao AN Chunlei Mike Rose | 2016 | Advances in Polar Science2016，27，2： | 2 |
| 3 | Simultaneous optical and radar observations of poleward moving auroral forms under different IMF conditions显示文摘Using high temporal resolution optical data obtained from three-wavelength all-sky imagers at Chinese Yellow River Station in the Arctic, together with the EISCAT Svalbard radar (ESR) and SuperDARN radars, we investigated the dayside poleward moving auroral forms (PMAFs) and the associated plasma features in the polar ionosphere under different interplanetary magnetic field (IMF) conditions, between 0900 and 1010 UT on 22 December 2003. Simultaneous optical and ESR observations revealed that all PMAFs were clearly associated with pulsed particle precipitations. During northward IMF, particles can precipitate into lower altitudes and reach the ionospheric E-region, and there is a reverse convection cell associated with these PMAFs. This cell is one of the typical signatures of the dayside high-latitude (lobe) reconnection in the polar ionosphere. These results indicate that the PMAFs were associated with the high-latitude reconnection. During southward IMF, the PMAFs show larger latitudinal motion, indicating a longer mean lifetime, and the associated ionospheric features indicate that the PMAFs were generated by the dayside low-latitude reconnection. | XING Zanyang YANG Huigen HAN Desheng WU Zhensen LIU Junming HU Zejun ZHANG Qinghe LIU Yonghua ZHANG Beichen HU Hongqiao | 2012 | Advances in Polar Science2012，23，4： | 2 |
| 4 | Dayside poleward moving auroral forms and ionospheric convection under stable interplanetary magnetic field (IMF) conditions显示文摘Using high temporal resolution optical data obtained from three-wavelength all-sky imagers over six winters continuously at Yellow River Station (78.92°N,11.93°E) in Arctic,we statistically investigated the dependence of location of poleward moving auroral forms (PMAFs) on the interplanetary magnetic field (IMF) B z and B y components as a function of MLT and MLAT under stable IMF conditions.It is found that more PMAFs occurred in lower latitude for Bz<0 and there was less evident IMF B y-related prenoon-postnoon asymmetry for Bz<0 than for Bz>0.We found that the PMAFs were distributed over a wide range of MLT when Bz<0,which indicates that the reconnection X-line might spread like an 'S' shape.However,during northward IMF,PMAFs were observed predominantly prenoon for IMF By>0 and postnoon for IMF By<0 associating with the effect of the high-latitude reconnection,which is largely consistent with the theoretical model of the convection flow. | XING ZanYang YANG HuiGen HAN DeSheng WU ZhenSen LIU JunMing HU ZeJun ZHANG QingHe HU HongQiao LIU YongHua | 2013 | Science China(Technological Sciences)2013，56，4： | 2 |
| 5 | Dynamic Response Solution of Multi-Layered Pavement Structure Under FWD Load Appling the Precise Integration Algorithm显示文摘The pavement layered structures are composed of surface layer,road base and multi-layered soil foundation.They can be undermined over time by repeated vehicle loads.In this study,a hybrid numerical method which can evaluate the displacement responses of pavement structures under dynamic falling weight deflectometer(FWD)loads.The proposed method consists of two parts:(a)the dynamic stiffness matrices of the points at the surface in the frequency domain which is based on the domain-transformation and dual vector form equation,and(b)interpolates the dynamic stiffness matrices by a continues rational function of frequency.The mixed variables formulation(MVF)can treat multiple degree of freedom systems with considering the coupling term between degree of freedoms.The accuracy of the developed method has been demonstrated by comparison between the proposed method and published results from the other method.Then the proposed method can be applied as a forward calculation technique to emulate the falling weight deflectometer test for multi-layered pavement structures. | Zejun Han Hongyuan Fang Juan Zhang Fuming Wang | 2019 | Computers, Materials & Continua2019，，6： | 1 |

| 8 | Effect of interplanetary shock on an ongoing substorm:Simultaneous satellite-ground auroral observations显示文摘Substorm processes have been studied in detail,and it is well known that interplanetary(IP)shock encountering the terrestrial magnetosphere causes global responses.However,how IP shock compression to the magnetosphere affects the development of an ongoing substorm remains uninvestigated.Herein,the simultaneous satellite and ground-based auroral evolutions associated with an IP shock impact on the magnetopause during an ongoing substorm on May 7th,2005,were examined.The IMAGE satellite over the Southern Hemisphere captured the global development substorm,which was initiated at 17:38:47 UT.The poleward branch of the nightside auroral oval was fortuitously monitored by an all-sky camera at the Zhongshan Station(-74.5°magnetic latitude,ZHO)in Antarctica.The satellite imager observed continuous brightening and broadening of the nightside auroral oval after the IP shock arrival.The simultaneous ground-based optical aurora measurement displayed the intensification and expansion of a preexisting auroral surge poleward of the aurora oval.The geomagnetic field variations and the instantly increased PC indices indicated an elevated merging rate and enhanced the convection-related DP-2 currents.Therefore,this IP shock transient impact did not significantly change the ongoing development of the substorm,although it meets the magnetospheric precondition hypothesis. | LIU JianJun CHEN XiangCai WANG ZhiQiang HU ZeJun ZHAO XingXin HU HongQiao HAN DeSheng LUI A.T.Y | 2023 | Science China(Technological Sciences)2023，66，3： | 1 |

| 10 | Hardware Circuit Implementation and Performance Analysis of Three-Slot NP-CSMA显示文摘The development of wireless communication technology has become increasingly important in the communications industry.How to allocate limited channel resources reasonably and reliably to each competing user is a problem that the access protocol of the MAC(Multiple Access Control)layer needs to solve.As an important way of random access,NP-CSMA(Non Persistent Carrier Sense Multiple Access)has a higher network throughput rate when the arrival rate is higher.This paper analyzes and improves the implemented NP-CSMA model,and obtains a three-slot NP-CSMA model.The mathematical tool MATLAB is used to analyze the network throughput,delay and energy efficiency of the model,and compare several random multiple access protocols adheres to the network throughput,they are NP-CSMA,Three-slot NP-CSMA,1-persistent CSMA,P-persistent CSMA,and concludes that the three-slot NP-CSMA is significantly letter than several other multiple access protocols.Finally,using Quartus to design the three-slot NP-CSMA circuit,the statistical value of the circuit system is compared with the theoretical value of the model,and the error is less than 0.01,which proves that the system is reasonable in design and can be applied to wireless communication networks. | Xu Lu Hongwei Ding Zejun Han Zhijun Yang Liqing Wang Liyong Bao | 2019 | Computer Modeling in Engineering & Sciences2019，，6： | 0 |
| 11 | PtCu-SnO_(2)nanocomposites for ultrasensitive and rapid ultra-low formaldehyde sensing显示文摘SnO 2 nanospheres with diameters of 30∼50 nm and Pt x Cu 1-x bimetallic nanoparticles with sizes of approxi-mately 10 nm were synthesized via hydrothermal and solvothermal methods,respectively.The Pt x Cu 1-x bimetal-lic nanoparticles were impregnated on the surface of the SnO 2 spheres to form Pt x Cu 1-x-SnO 2 nanocomposites.By varying the atomic ratios between platinum(Pt)and copper(Cu),we found that Pt 0.75 Cu 0.25-SnO 2,with a large specific surface area of 89.21 m 2/g,enabled the selective and accurate detection of low-concentration formalde-hyde compared to other metal-deposited samples and pure SnO 2.The response value of Pt 0.75 Cu 0.25-SnO 2 to 500×10−9 formaldehyde was approximately 20 at an operating temperature of 160◦C with an extremely high-speed response(15 s).The porous structures with large specific surface areas,as well as the improved catalytic effects of Pt 0.75 Cu 0.25,comprehensively contributed to the enhanced sensing performance towards formaldehyde. | Zejun Han Yunxiang Tang Guixia Lu Yuan Qi Hao Wu Zhengyi Yang Hecheng Han Xue Zhang Lili Wu Zhou Wang Jiurong Liu Fenglong Wang | 2022 | ChemPhysMater2022，1，3： | 0 |
| 12 | Organophosphine ligand derived sandwich-structural electrocatalyst for oxygen evolution reaction显示文摘The synchronous construction of metal phosphate and phosphorus-doped carbon structures is of great significance to innovate the design,synthesis,and application of catalysts,as these phosphoruscontaining composite materials have shown a remarkable contribution to electrocatalysts.However,their preparation procedure generally involves using large amounts of excess phosphorus sources for phosphorization,which inevitably release poisonous PH_(3) or dangerous phosphorus vapor.Here,a strategy for in-situ formation of FePO_(4) embedded in P-doped carbon 2D nano film(FePO_(4)/PdC)is developed using a highly integrated precursor,which is a small molecular organophosphine ligand,1,1’bis(diphenylphosphine)ferrocene(DPPF).The multi-source precursor DPPF that contains Fe,P,and C is molecular-vapor-deposited on the nickel foam(NF)supported ZIF-67 nanosheets to obtain the composite catalyst,namely DPPF-500/ZIF-67/NF.FePO_(4)/PdC encapsulated the ZIF-67 derived Co/N-doped carbon matrix(Co NC)to form a sandwich structure FePO_(4)/PdC@CoNC.The constructed catalyst shows good performance for OER,requiring an overpotential of only 297 m V to deliver 600 m A/cm^(2) with a Tafel slope of 42.7 m V dec^(-1).DFT calculations demonstrate that the synergistic effects between the metal active center and P-doped carbon film reduce the energy barriers and improve electron transport.This method of constructing P-containing catalysts overcomes the demand for additional P sources to realize eco-friendly fabrication and yields a unique structure with good catalytic activity. | Zejun Sun Wenjuan Xu Liutao Guo Qiang Han Jianyi Gao Jiaping Wang Yanru Feng Chengrui Li Qionglin Liang Hong-bin Sun Yang Yang | 2022 | Journal of Energy Chemistry2022，31，7： | 0 |
| 13 | Catalytically active atomically thin cuprate with periodic Cu single sites显示文摘Rational design and synthesis of catalytically active two-dimensional(2D)materials with an abundance of atomically precise active sites in their basal planes remains a great challenge.Here,we report a ligand exchange strategy to exfoliate bulk[Cu_(4)(OH)_(6)][O_(3)S(CH_(2))_4SO_(3)]cuprate crystals into atomically thin 2D cuprate layers([Cu_(2)(OH)_(3)]^(+)).The basal plane of 2D cuprate layers contains periodic arrays of accessible unsaturated Cu(Ⅱ)single sites(2D-CuSSs),which are found to promote efficient oxidative Chan-Lam coupling.Our me chanistic studies reveal that the reactions proceed via coordinatively unsaturated CuO_4(Ⅰ)single sites with the formation of Cu(Ⅰ)species in the rate-limiting step,as corroborated by both operando experimental and theoretical studies.The robust stability of 2D-CuSSs in both batch and continuous flow reactions,coupled with their recyclability and good performance in complex molecule derivatization,render 2D-CuSSs attractive catalyst candidates for broad utility in fine chemical synthesis. | Huimin Yang Shibo Xi Na Guo Mu Wang Lingmei Liu Pin Lyu Xiaolong Yu Jing Li Haomin Xu Xiao Hai Zejun Li Xinzhe Li Tao Sun Xiaoxu Zhao Yu Han Wei Yu Jie Wu Chun Zhang Honghan Fei Ming Joo Koh Jiong Lu | 2023 | National Science Review2023，10，1： | 0 |
