2Analysis of severe human adenovirus infection outbreak in Guangdong Province,southern China in 2019显示文摘During 2018–2019,a severe human adenovirus(HAdV)infection outbreak occurred in southern China.Here,we screened 18 respiratory pathogens in 1704 children(≤14 years old)hospitalized with acute respiratory illness in Guangzhou,China,in 2019.In total,151 patients had positive HAdV test results;34.4%(52/151)of them exhibited severe illness.HAdV infection occurred throughout the year,with a peak in summer.The median patient age was 3.0(interquartile range:1.1–5.0)years.Patients with severe HAdV infection exhibited increases in12 clinical indexes(P≤0.019)and decreases in four indexes(P≤0.007),compared with patients exhibiting nonsevere infection.No significant differences were found in age or sex distribution according to HAdV infection severity(P>0.05);however,the distributions of comorbid disease and HAdV co-infection differed according to HAdV infection severity(P<0.05).The main epidemic types were HAdV-3(47.0%,71/151)and HAdV-7(46.4%,70/151).However,the severe illness rate was significantly higher in patients with HAdV-7(51.4%)than in patients with HAdV-3(19.7%)and other types of HAdV(20%)(P<0.001).Sequencing analysis of genomes/capsid genes of 13 HAdV-7 isolates revealed high similarity to previous Chinese isolates.A representative HAdV-7isolate exhibited a similar proliferation curve to the curve described for the epidemic HAdV-3 strain Guangzhou01(accession no.DQ099432)(P>0.05);the HAdV-7 isolate exhibited stronger virulence and infectivity,compared with HAdV-3(P<0.001).Overall,comorbid disease,HAdV co-infection,and high virulence and infectivity of HAdV-7 were critical risk factors for severe HAdV infection;these data can facilitate treatment,control,and prevention of HAdV infection.Wenkuan Liu Shuyan Qiu Li Zhang Hongkai Wu Xingui Tian Xiao Li Duo Xu Jing Dai Shujun Gu Qian Liu Dehui Chen Rong Zhou 2022Virologica Sinica2022,37,3:5
3Implantable nerve guidance conduits:Material combinations,multi-functional strategies and advanced engineering innovations显示文摘Nerve guidance conduits(NGCs)have attracted much attention due to their great necessity and applicability in clinical use for the peripheral nerve repair.Great efforts in recent years have been devoted to the development of high-performance NGCs using various materials and strategies.The present review provides a comprehensive overview of progress in the material innovation,structural design,advanced engineering technologies and multi functionalization of state-of-the-art nerve guidance conduits NGCs.Abundant advanced engineering technologies including extrusion-based system,laser-based system,and novel textile forming techniques in terms of weaving,knitting,braiding,and electrospinning techniques were also analyzed in detail.Findings arising from this review indicate that the structural mimetic NGCs combined with natural and synthetic materials using advanced manufacturing technologies can make full use of their complementary advantages,acquiring better biomechanical properties,chemical stability and biocompatibility.Finally,the existing challenges and future opportunities of NGCs were put forward aiming for further research and applications of NGCs.Yixin Yan Ruotong Yao Jingyuan Zhao Kaili Chen Lirong Duan Tian Wang Shujun Zhang Jinping Guan Zhaozhu Zheng Xiaoqin Wang Zekun Liu Yi Li Gang Li 2022Bioactive Materials2022,7,5:4
4Photocatalytic H2 Evolution on TiO2 Assembled with Ti3C2 MXene and Metallic 1T-WS2 as Co-catalysts显示文摘The biggest challenging issue in photocatalysis is efficient separation of the photoinduced carriers and the aggregation of photoexcited electrons on photocatalyst’s surface.In this paper,we report that double metallic co-catalysts Ti3C2 MXene and metallic octahedral(1T)phase tungsten disulfide(WS2)act pathways transferring photoexcited electrons in assisting the photocatalytic H2 evolution.TiO2 nanosheets were in situ grown on highly conductive Ti3C2 MXenes and 1T-WS2 nanoparticles were then uniformly distributed on TiO2@Ti3C2 composite.Thus,a distinctive 1T-WS2@TiO2@Ti3C2 composite with double metallic co-catalysts was achieved,and the content of 1T phase reaches 73%.The photocatalytic H2 evolution performance of 1T-WS2@TiO2@Ti3C2 composite with an optimized 15 wt%WS2 ratio is nearly 50 times higher than that of TiO2 nanosheets because of conductive Ti3C2 MXene and 1T-WS2 resulting in the increase of electron transfer efficiency.Besides,the 1T-WS2 on the surface of TiO2@Ti3C2 composite enhances the Brunauer–Emmett–Teller surface area and boosts the density of active site.Yujie Li Lei Ding Shujun Yin Zhangqian Liang Yanjun Xue Xinzhen Wang Hongzhi Cui Jian Tian 2020Nano-Micro Letters2020,12,1:4
5CFD-Based Optimal Design of Duct Nets in Hydraulic Manifold Block显示文摘This paper introduces a CFD-aided optimal design method for duct nets.Based on the structured frame,this method can help to improve the dynamic performance in the inner flow field of hydraulic manifold blocks (HMB).With the grid from geometry model of structured duct nets and the initial and boundary conditions from testing,the transient inner flow field of HMB duct nets is simulated.Basic flow characteristics in duct nets are obtained.Important factors involved are discussed and the procedures are illustrated.ZHANG Hong TIAN Shujun GAO Yanming JIA Chunqiang (School of Mechanical Engineering,Dalian University of Technology,Dalian 116023,China 2006武汉理工大学学报2006,28,S2:2
6Electrical properties of yttrium calcium oxyborate crystal annealed at high temperature and low oxygen partial pressure显示文摘The yttrium calcium oxyborate crystal(YCa_(4)O(BO_(3))_(3),YCOB)has been actively studied for hightemperature piezoelectric sensing applications.In this work,the stability of electric properties of YCOB crystal annealed in critical conditions(high-temperatures of 900-1100℃ with a low oxygen partial pressure of 4×10^(-6) atm for 24 h)was investigated and the recovery mechanism for the electrical resisitivity,dielectric permittivity and dielectric loss were studied,taking advantage of the X-ray photoelectron spectra and the first principle calculations.The electrical resistivity of the annealed YCOB crystal was slightly decreased when compared to the pristine counterpart,being(2-5)×10^(7) Ω·cm at 850C.The dielectric permittivity and dielectric loss were found to increase after annealing,showing recoverable behaviours after thermal treatment above 650℃ in air.The calculated vacancy formation energy indicates that the oxygen vacancy is the dominant defects in YCOB.The formation of oxygen vacancy weakens the chemical bonding strength between B(Ca or Y)and O atoms,introduces extra donor levels in the band gap,which excites the electrons to conduction band more easily thus enhances the electrical conductivity and dielectric loss.The recovered electrical properties are believed to be associated with the reduced vacancy defects at elevated temperatures in air.Shiwei Tian Lili Li Feifei Chen Chao Jiang Fapeng Yu Yanlu Li Xiulan Duan Zhengping Wang Shujun Zhang Xian Zhao 2019Journal of Materiomics2019,5,3:2

12Research and development of prevention and control measures on the transmission of pathogens in compartments of passenger transport显示文摘Contagious pathogens like COVID-19 transmitted via respiratory droplets spread effortlessly in the passenger compartments of transport,significantly jeopardizing passengers’safety when taking public transportation.To date,studies on the fundamental theories of airborne droplet transmission and the engineering application of decontamination techniques are insufficient for the prevention and control of pathogens transmitting in the compartments of passenger transport.It is essential to systematically investigate the control approaches to restrain pathogens from transmitting in passenger compartments.Herein,a theoretical framework for calculating the transmission of pathogens in a complex compartment environment was proposed,and experimental platforms that satisfy the Biosafety Level-2 Laboratory safety level for compartment environment simulations were built based on a set of real train cabins.On these bases,numerical investigations on the motion of pathogen-laden droplets were conducted,and decontamination techniques were examined experimentally.Thereby,control measures on the pathogen transmission and pathogen decontamination schemes were proposed.Moreover,highly efficient decontamination devices were developed,and coping strategies for epidemic emergencies were devised.The outcomes provide theoretical and technical support for developing the next generation of transportation and the prevention and control measures cooperatively considering regular and pandemic times.Hongqi Tian Tiantian Wang Lei Xu Miao Sha Shujun Chen Zeyun Yang Yan Zhu Dawei Chen Hengkui Li Lei Zhang Bosen Qian Xudong Tian 2024Transportation Safety and Environment2024,6,1:0
13Impacts of solid physical properties on the performances of a slurry external airlift loop reactor integrating mixing and separation显示文摘Solid physical properties are vital for the design, optimization, and scale-up of gas–liquid–solid multiphase reactors. The complex and interactional effects of the solid physical properties, including particle diameter, density, wettability, and sphericity, on the hydrodynamic behaviors in a new external airlift loop reactor(EALR) integrating mixing and separation are decoupled in this work. Two semi-empirical equations are proposed and validated to predict the overall gas holdup and liquid circulating velocity satisfactorily, and then the individual influence of such solid physical properties is further investigated. The results demonstrate that both the overall gas holdup in the riser and the liquid circulating velocity in the downcomer increase with the contact angle, but decrease with particle size, density, and sphericity.Additionally, the impact of the particle size on the liquid circulating velocity is also profoundly revealed on a micro-level considering the particle size distribution. Moreover, the axial solid concentration distribution is discussed, and the uniformity of the slurry is described by the mixing index of the solid particles. The results show that a more homogeneous mixture can be achieved by adding finer particles other than attaining violent turbulence. Therefore, this work lays a foundation for the design, scale-up, and industrialization of the EALRs.Tian Zhang Qingshan Huang Shujun Geng Aqiang Chen Yan Liu Haidong Zhang 2023Chinese Journal of Chemical Engineering2023,55,3:0

15Scalable Fabrication of Metallic Conductive Fibers from Rheological Tunable Semi-Liquid Metals显示文摘Conductive polymer fibers/wires(CPFs)are important materials in modern technologies due to their unique one-dimension geometry,electrical conductivity,and flexibility.However,the advanced applications of current CPFs are limited by their low electrical conductivities(<500 S/m)and poor interfacial interactions between conductive fllers(e.g.,graphite)and polymers.Therefore,in current electrical applications,metal wires/foils like copper and aluminum are the most frequently utilized conductive fibers/wires instead of the inferior conductive CPFs.This work successfully addresses the heavy phase segregation between polymers and conductive inorganic materials to obtain semiliquid metal polymer fibers(SLMPFs)which exhibit an ultrahigh electrical conductivity(over 10^(6)S/m),remarkable thermal processability,and considerable mechanical performance(Young's modulus:~300 MPa).Semiliquid metal(gallium-tin alloy)with tunable viscosities is the key to achieve the excellent miscibility between metals and polymers.Both the rheological results and numerical simulations demonstrate the critical viscosity matching for the successfui preparation of the fibers.More importantly,the fibers are adapted with classic polymer melt-processing like melt injection,which indicates the scalable production of the highly conductive fibers.The SLMPFs are highly promising substitutes for metal wires/fbers in modern electrical applications such as electricity transmission,data communication,and underwater works.Shujun Tian Hao Peng Huaizhi Liu Jiancheng Zhou Jiuyang Zhang 2023Research2023,,1:0
