Zincophilic property and high electrical conductivity are both very important parameters to design novel Zn anode for aqueous Zn-ion batteries(AZIBs).However,single material is difficult to exhibit zincophilic property and high electrical conductivity at the same time.Herein,originating from theoretical calculation,a zincophilic particle regulation strategy is proposed to address these limitations and carbon coated Na_(3)V_(2)(PO_(4))_(3)is taken as an example to be a protective layer on zinc metal(NVPC@Zn).Na_(3)V_(2)(PO_(4))_(3)(NVP)is a common cathode material for Zn-ion batteries,which is zincophilic.Carbon materials not only offer an electron pathway to help Zn deposition onto NVPC surface,but also enhance the zinc nucleophilicity of Na_(3)V_(2)(PO_(4))_(3).Hence,this hybrid coating layer can tune zinc deposition and resist side reactions such as hydrogen generation and Zn metal corrosion.Experimentally,a symmetrical battery with NVPC@Zn electrode displays highly reversible plating/stripping behavior with a long cycle lifespan over 1800 h at2 mA cm^(-2),much better than carbon and Na_(3)V_(2)(PO_(4))_(3)solely modified Zn electrodes.When the Na_(3)V_(2)(PO_(4))_(3)is replaced with zincophobic Al2O3or zincophilic V2O3,the stability of the modified zinc anodes is also prolonged.This strategy expands the option of zincophilic materials and provides a general and effective way to stabilize the Zn electrode.

Computer Modeling in Engineering & Sciences 2024年第3期138卷 2727-2748页

作者： Jun Xu Kai Bi Yibin lu TiantianWang Hang Zhang Zeyuan Zheng Fushan Shi Yaxin Zheng xiaoying Li Jingping Yang CRRC Changchun Railway Vehicles Co. Ltd.Changchun130062China Key Laboratory of Traffic Safety on Track Ministry of EducationSchool of Traffic&Transportation EngineeringCentral South UniversityChangsha410075China College of Mechanical and Vehicle Engineering Hunan UniversityChangsha410082China

The spread and removal of pollution sources,namely,cough-released droplets in three different areas(front,middle,and rear areas)of a fully-loaded passenger car in a high-speed train under different fresh air flow volume were studied using computational fluid dynamics(CFD)method.In addition,the structure of indoor flow fields was also analysed.The results show that the large eddies are more stable and flow faster in the air supply under Mode 2(fresh air volume:2200m3/h)compared to Mode 1(fresh air volume:1100m3/h).By analysing the spreading process of droplets sprayed at different locations in the passenger car and with different particle sizes,the removal trends for droplets are found to be similar under the two air supply modes.However,when increasing the fresh air flow volume,the droplets in the middle and front areas of the passenger car are removed faster.When the droplets had dispersed for 60s,Mode 2 exhibited a removal rate approximately 1%–3%higher than Mode 1 for small and medium-sized droplets with diameters of 10 and 50μm.While those in the rear area,the situation is reversed,with Mode 1 slightly surpassing Mode 2 by 1%–3%.For large droplets with a diameter of 100μm,both modes achieved a removal rate of over 96%in all three regions at the 60 s.The results can provide guidance for air supply modes of passenger cars of high-speed trains,thus suppressing the spread of virus-carrying droplets and reducing the risk of viral infection among passengers.

This study aimed to explore the effect of Bifidobacterium animalis F1-7 on the improvement of atherosclerotic inflammation.Arteriosclerosis model ApoE^(-/-)mice were orally administered with B.animalis F1-7 for 12 weeks.The probiotic intervention reduced the plaque areas in aorta and the accumulation of macrophages,and downregulated the expression of toll-like receptor 4(TLR4)/nuclear factorκB(NF-κB)pathway to reduce the levels of inflammatory factors.The widely-targeted metabolomics analysis showed that acetyl-L-carnitine(ALC)in the intestine of atherosclerotic mice was significantly increased after B.animalis F1-7 intervention.Correlation analysis proved that ALC was associated with atherosclerotic inflammatory response.By using oxidized low density lipoprotein induced macrophage foam cells,we further verified that ALC could reduce lipid accumulation and inflammatory response in foam cells by downregulating the TLR4/NF-κB pathway.Finally,our results revealed that B.animalis F1-7 upregulated the metabolite ALC to downregulate the inflammatory responses,leading to the reduction of plaque accumulation of atherosclerosis.

Asian Journal of Urology 2022年第2期9卷 177-185页

作者： Jie Cao Chunxue Peng xiaoying lu Lingjun Zhou Jing Wu Department of Urology Changhai HospitalNaval Medical UniversityShanghaiChina Department of Nursing Changhai HospitalNaval Medical UniversityShanghaiChina School of Nursing Naval Medical UniversityShanghaiChina

Objective:There was increasingly demand of participation in surgical decision-making among Chinese patients with prostate cancer.However,due to the complex healthcare system and advanced care settings,it is quite challenging for the patients to gain sufficient support from the institute and the government.This research aimed to investigate the factors that impact the degree of participation in surgical decision-making among Chinese prostate cancer patients.Methods:A phenomenological approach of qualitative research based on the results of semi-structured interviews was adopted,to explore the influencing factors which hinder the participation in surgical decision-making.Consolidated Criteria for Reporting Qualitative Research were utilized.Up to 160 post-operative patients who had undergone radical prostatectomy along with 68 medical and nursing staffs,were purposively recruited in this research.This retrospective study was carried out from September 2018 to August 2019.After recording and transcribing the interviews,the interview materials were evaluated via the Colaizzi's seven step approach and the NVivo Version 10 software to analyze the interview content.Results:According to the analysis and summary of the interviews,there were three factors affecting the degree of participation in surgical decision-making.Firstly,insufficient information was provided by medical and nursing staffs because of their lack of time,proper communication skills,and career experience,as well as difficulties in the development of patient decision aid and inconsistent resource availability.Secondly,the cognitive level of decision-making among patients was relatively low due to poor psychological endurance,insufficient amount of education,senility,and less knowledge and information demand.Ultimately,decisions were constantly made by family members with/without patients.Conclusions:The degree of participation of Chinese prostate cancer patients in the surgical decision-making had much space for improvement.

Green Energy & Environment 2022年第4期7卷 755-762页

作者： Xuyan Wang Jianwei Bai Yantao Wang xiaoying lu Zehua Zou Junfeng Huang Cailing Xu State Key Laboratory of Applied Organic Chemistry Laboratory of Special Function Materials and Structure Design of the Ministry of EducationCollege of Chemistry and Chemical EngineeringLanzhou UniversityNo.222 Tianshui South RoadLanzhou730000China Lanzhou No.11 Middle School No.523 Pingliang RoadLanzhou730000China

Tuning surface electron transfer process by sulfur(S)-vacancies engineering is an efficient strategy to develop high-efficient catalysts for electroreduction N_(2) reaction(NRR). Herein, the distinct Sb_(2)S_(3) nanorods with S-vacancies(Sv-Sb_(2)S_(3)) have been synthesized by a simple twostep method including hydrothermal and hydrogenation in H_(2)/Ar atmosphere, which shows improved performance for NRR with the NH_(3) yield rate of 10.85 μg h^(-1) mgcat^(-1) at-0.4 V vs. RHE, the faradaic efficiency(FE) of 3.75% at -0.3 V vs. RHE and excellent stability for 24 h, largely outperforming bulk Sb_(2)S_(3). X-ray photoelectron spectroscopy(XPS) and density function theory(DFT) calculations demonstrate that the abundant S-vacancies can create an electron-deficient environment and modulate the electron delocalization in Sv-Sb_(2)S_(3), which can not only facilitate the N_(2) molecule adsorption, but also activate the N≡N, resulting in the enhanced performance for NRR.

作者： Zhiyu Zhang Yang Zhao xiaoying Han Liling Li Bo Qing Lifei Hou Yulong Li YuXue Zhang Huan Zhang Xiangming Liu Bo Deng Gang Xiong Min Lv Tuo Zhu Chengwu Huang Tianming Song Yan Zhao Yingjie Li lu Zhang Xufei Xie Jiyan Zhang Jiamin Yang Laser Fusion Research Center China Academy of Engineering PhysicsMianyang 621900China National Key Laboratory of Plasma Physcis Mianyang 621900China Institute of Applied Physics and Computational Mathematics Beijing 100088China

A self-consistent and precise method to determine the time-dependent radiative albedo,i.e.,the ratio of the reemission flux to the incident flux,for an indirect-drive inertial confinement fusion Hohlraum wall material is proposed.A specially designed symmetrical triple-cavity gold Hohlraum is used to create approximately constant and near-equilibrium uniform radiation with a peak temperature of 160 eV.The incident flux at the secondary cavity waist is obtained from flux balance analysis and from the shock velocity of a standard sample.The results agree well owing to the symmetrical radiation in the secondary cavity.A self-consistent and precise time-dependent radiative albedo is deduced from the reliable reemission flux and the incident flux,and the result from the shock velocity is found to have a smaller uncertainty than that from the multi-angle flux balance analysis,and also to agree well with the result of a simulation using the HYADES opacity.

Regenerative Biomaterials 2020年第6期7卷 553-565页

作者： xiaoying lu Yan Huang Yayun Qu Yiwen Zhang Zequn Zhang State Key Laboratory of Bioelectronics School of Biological Science and Medical EngineeringSoutheast UniversityNanjing 210096China SQ Medical Device Co. LtdNanjing 210008China

The purpose of this article is to integrate the transcriptomic analysis and the proteomic profiles and to reveal and compare the different molecular mechanisms of PC12 cell growth on the surface of chitosan films and collagen/chitosan films.First,the chitosan films and the collagen/chitosan films were prepared.Subsequently,the cell viability assay was performed;the cell viability of the PC12 cells cultured on the collagen/chitosan films for 24 h was significantly higher than that on the chitosan films.Then,with cDNA microarray,the numbers of differentially expressed genes of PC12 cells on the surface of chitosan and collagen/chitosan films were 13349 and 5165,respectively.Next,the biological pathway analysis indicated that the differentially expressed genes were involved in 40 pathways directly related to cell adhesion and growth.The integrated transcriptomic and our previous proteomic analysis revealed that three biological pathways-extracellular matrix-receptor interaction,focal adhesion and regulation of actin cytoskeleton-were regulated in the processes of protein adsorption,cell adhesion and growth.The adsorbed proteins on the material surfaces further influenced the expression of important downstream genes by regulating the expression of related receptor genes in these three pathways.In comparison,chitosan films had a strong inhibitory effect on PC12 cell adhesion and growth,resulting in the significantly lower cell viability on its surface;on the contrary,collagen/chitosan films were more conducive to promoting PC12 cell adhesion and growth,resulting in higher cell viability.

The aim of this article is to reveal the influence of aligned/random poly(L-lactic acid)(PLLA)nanofibers on PC12 cell differentiation from the perspective of metabolic level.First,three materials-PLLA aligned nanofibers(PLLA AF),PLLA random nanofibers(PLLA RF)and PLLA films(control)-were prepared by electrospinning and spin coating.Their surface morphologies were characterized.Subsequently,the cell viability,cell morphology and neurite length of PC12 cells on the surface of the three materials were evaluated,indicating more neurites in the PLLA RF groups but the longer average neurite length in the PLLA AF groups.Next,the metabolite profiles of PC12 cells cultured on the surface of the three nanofibers after 12 h,24 h and 36 h showed that,compared with the control,51,48 and 31 types of differential metabolites were detected at the three time points among the AF groups,respectively;and 56,45 and 41 types among the RF groups,respectively.Furthermore,the bioinformatics analysis of differential metabolites identified two pathways and three metabolites critical to PC12 cell differentiation influenced by the nanofibers.In addition,the verification experiment on critical metabolites and metabolic pathways were performed.The integrative analysis combining cytology,metabolomics and bioinformatics approaches revealed that though both PLLA AF and RF were capable of stimulating the synthesis of neurotransmitters,the PLLA AF were more beneficial for PC12 cell differentiation,whereas the PLLA RF were less effective.
