| 1 | Analysis of the mass of behind-armor debris generated by RHA subjected to normal penetration of variable cross-section EFP显示文摘Analyzing the mass of behind-armor debris (BAD) generated by Rolled Homogeneous Armor (RHA) subjected to normal penetration of variable cross-section Explosively Formed Projectile (EFP) is the purpose of this paper. So theoretical analysis, numerical simulation and experimental data are combined to analyze the influence of variable cross-section characteristic on the time history of crater radius. Moreover the relationships between time history of crater radius (as well as mass of BAD) and the thickness of RHA (from 30mm to 70 mm) and the impact velocity of EFP (1650 m/s to 1860 m/s) are also investigated. The results indicate that: 1) being compared to the variable cross-section characteristic is ignored, the theoretical time history of crater radius is in better agreement with the simulation results when the variable cross-section characteristic is considered;2) being compared to the other three conditions of plug, the theoretical mass of BAD is in the best agreement with the simulation results when the shape of plug is frustum of a cone and the angle between generatrix and bottom is 45- and the axial length of mushroom is considered. | Boyang Xing Dongjiang Zhang Zhenyan Guo Yunhui Hou Rui Guo Rongzhong Liu Liang Chen Hao Zhou Yongliang Yang Jianhua Luo | 2019 | Defence Technology(防务技术)2019，15，3： | 4 |
| 2 | Hierarchical red phosphorus incorporated TiO_(2) hollow sphere heterojunctions toward superior photocatalytic hydrogen production显示文摘Solar-to-hydrogen conversion through photocatalysis is a sustainable and promising strategy for storing solar energy.Recently,elemental red phosphorus(RP)with broad light absorption has been recognized as a potential candidate for photocatalytic hydrogen evolution,while challenges remain due to the rapid recombination of photogenerated carriers.In this work,RP modified TiO_(2)hollow spheres were designed and fabricated through the chemical vapor deposition method.The optimal hydrogen production rate reaching 215.5μmol/(g h)over TiO_(2)@RP heterostructure was obtained under simulated solar light irradiation.Experimental results evidenced that the hollow sphere structure and RP light absorber extended light absorption ability,and the heterostructure induced interfacial charge migration facilitated photoinduced charge separation,which benefited the photocatalytic hydrogen production performance. | Guiqing Huang Wanneng Ye Chunxiao Lv Denys S.Butenko Chen Yang Gaolian Zhang Ping Lu Yan Xu Shuchao Zhang Hongwei Wang Yukun Zhu Dongjiang Yang | 2022 | Journal of Materials Science & Technology2022，，13： | 3 |

| 4 | Polybenzimidazole functionalized electrolyte with Li-wetting and self-fluorination functionalities for practical Li metal batteries显示文摘Rough Li plating,low ionic conductivity,and low thermal stability of conventional electrolytes post-primary challenges for achieving reliable high-capacity rechargeable lithium batteries,for which lithiummetal is frequently proposed as themost promising anode material.Conventional low-polarity commercial polypropylene/polyethylene separators fail to support the application of high-energy-density Li anodes due to their rigid physicochemical properties and the high reactivity of Li metal,leading to fatal dendrite formation and vigorous exothermic reaction with electrolytes.Herein,we develop a Li-wetting,flame-retardant binary polymer electrolyte by functionalizing poly(vinylidene fluoride)(PVDF)separators with nonflammable polybenzimidazole(PBI)to build safe room-temperature solid-state electrolyte membranes.A dendrite-free LiFePO4 cell with the solid polymer electrolyte(SPE)delivers a discharge capacity of 127 mAh g^(-1) at 25℃ with a capacity retention of 87.5%after 500 cycles at 0.5℃(0.15 mA cm^(-2)).Phase-field simulations and density functional theory calculations demonstrate that the negatively charged benzimidazole chains of PBI own superior affinity to lithium bis(trifluoromethanesulfonyl)imide(LiTFSI),and shares overlapping electron density with Li anode,giving rise to accelerated Li^(+)conduction at room temperature and uniform Li electrodeposition at the electrolyte/Li metal interface.The SPE is also flame-retardant since heat-resistant polytetrafluoroethylene and a dense,heat-blocking graphitized carbon layer are formed in intense heat throughdehydrogenation/fluorination of PVDF under the catalysis of Lewis base imidazole rings and the decomposition of benzimidazole rings in PBI.No such fire-resistant mechanism is ever reported in conventional electrolytes. | Dongjiang Chen Yuanpeng Liu Chuan Xia Yupei Han Qingwei Sun Xuchang Wang Wei Chen Xian Jian Weiqiang Lv Jianyi Ma Weidong He | 2022 | InfoMat2022，4，5： | 1 |

| 10 | Boosting electrocatalytic hydrogen generation by a renewable porous wood membrane decorated with Fe-doped NiP alloys显示文摘Porous biomass electrodes have emerged as a critical material for electrocatalytic hydrogen evolution reaction(HER).However,most approaches for synthesizing porous electrodes from biomass require high energy consumption,which is resulted from the smash of biomass and the undergoing of serial assembly.Herein,a self-supported wood-derived'breathable'membrane is utilized directly as electrodes for highefficient HER via an assembly of Fe-doped NiP alloys.The well-designed hierarchical porous structures in natural wood membrane(NWM)are unusually beneficial for electrolytes accessibility and hydrogen gas removal.The obtained wood-derived membrane exhibits a high electrocatalytic activity and good cycling durability in acidic and alkaline electrolytes.Remarkably,the Fe_(0.074) NiP alloys/NWM electrode affords a large current density of 100 m A cm^(-2) at extremely low overpotentials of 168 mV in acidic electrolyte and174 m V in alkaline electrolyte.Density functional theory calculations unveil that the Fe atom doped in NiP alloys can create much more charge accumulation around Fe and Ni active sites,which helps decrease the △GH_(*)and △G_(H2O)and significantly promote the HER process.This new insight will promote further explorations of economic,high-efficient,and biodegradable wood-derived electrocatalysts for HER. | Bin Hui Jian Li Yun Lu Kewei Zhang Hongjiao Chen Dongjiang Yang Liping Cai Zhenhua Huang | 2021 | Journal of Energy Chemistry2021，30，5： | 1 |

| 12 | MoP QDs@graphene as highly efficient electrocatalyst for polysulfide conversion in Li-S batteries显示文摘The shuttle effect of lithium polysulfides(LiPSs)and sluggish redox conversion significantly hinder practical implementation of lithium-sulfur batteries(LSBs).To overcome these issues,herein,we present MoP quantum dots anchored N,P-doped graphene(MPQ@G)as a multifunctional LSB cathode.The N,P-doped graphene layers serve as a conductive skeleton to support the MoP QDs which can accelerate the electron transfer,physically hinder the polysulfide migration and thus enhance the electrochemical performance.More importantly,as a polar and conductive catalyst,MoP QDs provide catalytically active sites for the conversion of LiPSs.As a result,the LSBs with MPQ@G/S cathodes deliver an elevated initial capacity of 1220.2 mAh g~(-1)at 0.2 C and remain 98.9%after rate cycles,signifying its exceptional cycling stability.Moreover,it displays a large capacity of 681.2 mAh g~(-1)even at a high rate of 1 C.The Li-S pouch cell also presents high specific capacities and preeminent cycling stabilities,confirming its great potential for high-rate applications.Density functional theory calculations demonstrate the improved absorptivity and redox conversion reversibility of LiPSs.This work provides an efficient strategy to improve composite with highly adsorptive and catalytic properties for high-performance Li-S batteries. | Bo Yu Fei Ma Dongjiang Chen Katam Srinivas Xiaojuan Zhang Xinqiang Wang Bin Wang Wanli Zhang Zegao Wang Weidong He Yuanfu Chen | 2021 | Journal of Materials Science & Technology2021，，31： | 1 |

| 15 | Challenges and advances on low-temperature rechargeable lithiumsulfur batteries显示文摘Lithium-sulfur(Li-S)batteries have demonstrated the potential to conquer the energy storage related market due to the extremely high energy density.However,their performances at low temperature are still needed to be improved to broaden their applications.Therefore,in this review,the basic failure mechanisms and major challenges of Li-S battery at low temperature are categorized as the high desolvation barrier of Li^(+),uncontrolled nucleation and deposition of lithium,polysulfides clustering,and passivation of cathode by film like Li_(2)S.Targeting these major issues,strategies,and advances concerning the design of optimized electrolyte,composite cathode and functional separator are highlighted and discussed.Finally,the suggestions are proposed for the future development of practical Li-S battery working at low temperature scenarios,hoping to accelerate the commercialization process and bring revolution to the energy storage market. | Yu Jiao Fan Wang Yuhong Ma Sangang Luo Yaoyao Li Anjun Hu Miao He Fei Li Dongjiang Chen Wei Chen Tianyu Lei Yin Hu | 2023 | Nano Research2023，16，6： | 0 |
| 16 | Biochar aerogel-based electrocatalyst towards efficient oxygen evolution in acidic media显示文摘The controllable synthesis of oxygen evolution reaction(OER)electrocatalyst is an urgent need to advance the develop-ment of sustainable energy conversion and storage.However,the OER efficiency in acidic media is seriously hindered by slow reaction kinetics.The traditional acidic OER electrocatalysts are more prone to be oxidized and corroded as results of unstable carrier structures and variable electronic states of active species.Herein,a high-performing biochar aerogel(BA)based electrocatalyst were realistically designed and synthetized via joint utilization of the terrestrial lignin and seaweed polysaccharide as carbon sources.Originating from the induction effect of'egg-box'structure in alginate and the self-template effect of lignosulfonate,the BA decorated with Ru/RuS_(2)particles was synthesized triumphantly.The as-synthesized electrocatalyst required a low overpotential of 228 mV to attain 10 mA cm^(−2)in 0.5 M H_(2)SO_(4)and exhibited a good stability for over 12,000 s.The good activity was strongly dependent on the assembled unique two-dimensional/three-dimensional(2D/3D)channels in carbon aerogels.Notably,the numerous defective sites at carbon could strongly interact with the Ru/RuS_(2)heterojunction for remarkably enhancing the catalytic activity and stability of whole catalytic system in acidic media.This work puts forward a novel and effective strategy towards the enhancement of the acidic OER process by rational regu-lations of the BA and the coupling effect in micro-interface. | Bin Hui Hongjiao Chen Chengfeng Zhou Liping Cai Kewei Zhang Fengyu Quan Dongjiang Yang | 2022 | Biochar2022，4，1： | 0 |
| 17 | Ternary red phosphorus/CoP2/SiO2 microsphere boosts visible-light-driven photocatalytic hydrogen evolution from pure water splitting显示文摘Red phosphorus(RP) is a promising visible-light-driven semiconductor for photocatalytic hydrogen evolution,but the activity is restricted due to the rapid charge carrier recombination and sluggish surface reaction kinetics.Herein,cobalt phosphide(CoP_(2)) modified RP heterostructure was developed by in situ phosphorization of cobalt oxide from phosphorus vapor.By tuning the amounts of CoP_(2) in the heterostructure,the optimized hybrid exhibited a HER rate reaching 11.79 μmol h^(-1) under visible light illumination,which is 3.5 times higher than that of the RP with Pt as cocatalyst.It was experimentally indicated that the intimate interaction between CoP_(2) and RP gave rise to improved visible light absorption and accelerated photogenerated electron-holes separation.Moreover,the CoP_(2) as a noble-metal-free cocatalyst could promote the surface hydrogen evolution reaction,which synergetic benefited the photocatalytic hydrogen production activity. | Chen Yang Yukun Zhu Yiming Liu Hongwei Wang Dongjiang Yang | 2022 | Journal of Materials Science & Technology2022，，30： | 0 |
