| 1 | Freeze-drying-assisted Synthesis of Mesoporous CoMoO4 Nanosheets as Anode Electrode Material for Enhanced Lithium Batteries显示文摘A facile and green freeze-drying-assisted method was proposed to synthesize C0MoO4 mesoporous nano-sheets(MPNSs).The resulting product exhibits a Mgh specific capacity and good rate perfomance when evalimte an anode material for lithium-ion batteries(LIBs).The reversible specific capacity can be kept at 1105.2 mA·h·g^-1 after 100 cycles at a current density of 0.2 A/g.Even at the current densities of 1 and 4 A/gs the CoMoO4 MPNSs electrode can still retain the reversible capacities of 1148.7 and 540 mA·h·g^-1,respectively.Furthermore,the full cell(LiPePO4 catliode/CoMoO4 MPNSs anode)displays a stable discharge capacity of 146.7 mA·h·g^-1 at 0.1 C(1 C=170 mA/g)together with an initial coulombic efficiency of 98.2%.In addition,the CoMoO4 crystal structure is destroyed and reduced into Co^0 and Mo^0 in the first discharge process.In the subsequent cycles,the attractive Li storage properties come from the reversible conversions between Co/Co^2+and Mo/Mo^6+.The improved electroche-mical performance of CoMoO4 MPNSs is mainly attributed to their unique porous structures,which not only possess a good ion diffusion and electronic conduction pathway,but also provide many cavities to alleviate the volume changes during repeated cycling.This work offers a new perspective to the design of other porous electrode materials with a good energy storage performance. | WANG Wei WANG Tao FAN Xuecheng ZHANG Cuilin HU Jinxing CHEN Hui FANG Zhenxing YAN Jiefeng LIU Bing | 2019 | Chemical Research in Chinese Universities2019，35，2： | 1 |

| 8 | Three-dimensional flower-like SnS_(2)-supported bimetallic zeolite imidazole compound with enhanced electrocatalytic activity for methanol oxidation显示文摘Proton exchange membrane fuel cells(PEMFCs)are considered as one of the most effective technologies to resolve environmental problems and energy crisis for future automotive applications[1-4].The direct methanol fuel cell(DMFC)[5-6]is a new type of PEMFC using methanol as fuel[7].Because of its higher energy density and conversion efficiency,methanol can be used as direct fuel at a relatively lower operating temperature[8]with portable great potential in equipment and transportation utilization.Therefore,developing DMFCs that use methanol aqueous solution or steam methanol as fuel is a good choice to solve energy problems[9]. | Jinxing WANG Fang YU Zhenzhen GUO Lei YAN Xianbao WANG | 2021 | Frontiers of Materials Science2021，15，1： | 1 |

| 14 | The relationship between compartment models and their stochastic counterparts:A comparative study with examples of the COVID-19 epidemic modeling显示文摘Deterministic compartment models(CMs)and stochastic models,including stochastic CMs and agent-based models,are widely utilized in epidemic modeling.However,the relationship between CMs and their corresponding stochastic models is not well understood.The present study aimed to address this gap by conducting a comparative study using the susceptible,exposed,infectious,and recovered(SEIR)model and its extended CMs from the coronavirus disease 2019 modeling literature.We demonstrated the equivalence of the numerical solution of CMs using the Euler scheme and their stochastic counterparts through theoretical analysis and simulations.Based on this equivalence,we proposed an efficient model calibration method that could replicate the exact solution of CMs in the corresponding stochastic models through parameter adjustment.The advancement in calibration techniques enhanced the accuracy of stochastic modeling in capturing the dynamics of epidemics.However,it should be noted that discrete-time stochastic models cannot perfectly reproduce the exact solution of continuous-time CMs.Additionally,we proposed a new stochastic compartment and agent mixed model as an alternative to agent-based models for large-scale population simulations with a limited number of agents.This model offered a balance between computational efficiency and accuracy.The results of this research contributed to the comparison and unification of deterministic CMs and stochastic models in epidemic modeling.Furthermore,the results had implications for the development of hybrid models that integrated the strengths of both frameworks.Overall,the present study has provided valuable epidemic modeling techniques and their practical applications for understanding and controlling the spread of infectious diseases. | Ziyu Zhao Yi Zhou Jinxing Guan Yan Yan Jing Zhao Zhihang Peng Feng Chen Yang Zhao Fang Shao | 2024 | The Journal of Biomedical Research2024，38，2： | 0 |
| 15 | Critical evaluation of the glucose oxidase-like activity of gold nanoparticles stabilized by different polymers显示文摘Polymer stabilizers are widely used to synthesize gold nanoparticles(Au NPs)to prevent their aggregation and improve their stability.Although stabilizers are known to greatly influence both the structure and size of Au NPs,limited efforts explore their effects on the activity of Au NPs for biocatalysis.Herein,different polymers are used as stabilizers to synthesize Au NPs.For the glucose oxidase-like activity,we find that without the spatial barrier from stabilizers,naked Au NPs show significantly high catalytic activity as well as the worst stability.Among the polymers,polyacrylic acid-stabilized Au NPs exhibit the highest activity,whose Vmax(0.74μM·s^(−1))is higher than that of the natural glucose oxidase(0.37μM·s^(−1))due to the smallest particle size(<2 nm)and the weak spatial resistance of polyacrylic acid.These variable catalytic results derive from the comprehensive effects including size,steric hindrance,and electronic effect.However,further selectivity and activity tests have exposed shortcomings.They possess universal activities for aldose oxidation,whereas cannot retain activities in typical physiological environments.Our findings highlight the role of polymer stabilizers in imposing effects on the glucose oxidase-like activity of Au NPs and provide a basis for further Au NPs engineering and applications. | Lili Xu Jinxing Chen Qian Ma Daiyong Chao Xinyang Zhu Ling Liu Jin Wang Youxing Fang Shaojun Dong | 2023 | Nano Research2023，16，4： | 0 |
| 16 | Electrochemical drilling of small holes by regulating in real-time the electrolyte flowrate in multiple channels显示文摘Electrochemical drilling(ECD)provides an alternative technique for drilling multiple small holes in difficult-to-machine materials in numerous industrial applications such as for aeroengines.The value and fluctuation of electrolyte flowrate can seriously affect the machining stability and hole quality in ECD.In particular,when drilling multiple holes,the distribution and fluctuations of the electrolyte flowrate in each channel could influence the uniformity of the electrolyte flowrate among multiple tube electrodes,thereby affecting the machining stability and the maximum feed rate.Thus,an eight-channel flow control system was developed to measure and regulate in real time the electrolyte flowrate supplied into each individual tube electrode.This paper proposes ECD of small holes with real-time flowrate control to improve the uniformity of electrolyte flowrate in each tube electrode and reduce the fluctuations in the electrolyte flowrate.In single-hole drilling,when the electrolyte flowrate was regulated in real time,the hole quality and machining stability were considerably better than without regulation.This is because the electrolyte flowrate remains basically constant,which stabilizes the flow field.Moreover,by considering the hole profile,it was found that an electrolyte flowrate of 200.0 m L/min can be acceptable for ECD of small holes.When the eight-channel flow control system was used in multiple-hole drilling,the uniformity of the electrolyte flowrate in each tube electrode was obviously improved,which led to a more stable process.Additionally,the maximum feed rate can attain 2.40 mm/min in multiple-hole drilling.Based on these findings,a matrix(5×32)of multiple small holes was successfully fabricated with a satisfactory diameter consistency,as the machining stability and machining efficiency had been enhanced. | Jinxing LUO Xiaolong FANG Tao YANG Di ZHU | 2022 | Chinese Journal of Aeronautics2022，35，5： | 0 |
| 17 | A revisiting of transition metal phosphide(Cu_(3)P and FeP)nanozymes for two sugar-related reactions显示文摘Transition metal phosphides(TMPs)are essential catalysts for some general catalytic reactions.However,their potentials for biological catalysis have seldom been explored.Herein,we investigated the enzyme-like properties of four TMPs(FeP,CoP,Ni_(2)P,and Cu_(3)P)towards two sugar-related reactions.Among the four TMPs,Cu_(3)P nanoparticles(NPs)efficiently catalyzed the hydrolysis of glycosidic bonds as glycoside hydrolase mimics,and FeP NPs possessed both glucose oxidase-like(GOx-like)and peroxidase-like activities,which combined into a cascade reaction for glucose’s simple and one-step colorimetric biosensor without GOx.Cu_(3)P and FeP NPs with distinctive enzyme-like activities have shown unique biological catalysis potentials for further applications with an attractive and challenging goal of developing nanomaterials to mimic natural enzymes,which encourages more efforts to reveal TMP’s capabilities towards biocatalysis. | Daiyong Chao Zhixuan Yu Jinxing Chen Qing Dong Weiwei Wu Youxing Fang Ling Liu Shaojun Dong | 2023 | Nano Research2023，16，1： | 0 |
