2Effects of Y and Ce on Microstructures and Properties of Nb-Si System Composites显示文摘The effects of yttrium and cerium on microstructures and properties of Nb-Si system composites were investigated by scanning electron microscopy( SEM), energy dispersive spectrum(EDS), X-ray diffraction(XRD) and high temperature oxidation experiments.It is found that the coarse primary silicide phase became finer and more homogeneous with Y and Ce addition.The results of high temperature oxidation experiments show that the oxidation rates of NbSi system composites with an appropriate amount of Y and Ce decrease compared with those of alloys without Y or Ce addition, and oxidation products mainly distribute along the phase boundaries between the Nb solid solution and silicide.Qu Shiyu Han Yafang Song Jinxia Xiao Chengbo Song Liguo 2004Journal of Rare Earths2004,22,z1:4
3HSP70L1-mediated intracellular priming of dendritic cell vaccination induces more potent CTL response against cancer显示文摘Heat-shock protein(HSP)-based immunotherapy is established on its adjuvant effects when applied via an extracellular approach to pulse and activate dendritic cells(DCs).Our previous studies indicate that DCs pulsed with recombinant fusion proteins of antigenic fragment and HSP70-like protein 1(HSP70L1)are potent in stimulating antigen-specific Th1 responses.We herein evaluated the cytotoxic T cell(CTL)response by an intracellular approach of priming DCs with transfection of recombinant adenovirus-expressing the fusion gene of the 576–699 fragment of carcinoembryonic antigen(CEA)and HSP70L1.As compared with DCs pulsed with extracellular fusion protein,the DCs transfected with recombinant adenovirus expressing the fusion gene displayed equivalent mature phenotypes but less inflammatory appearance.However,the transfected DCs were superior to the pulsed DCs in inducing CEA-specific CTLs.Consistently,immunization of HLA-A2.1/H-2Kb transgene mice with the transfected DCs could induce more quantities of HLA-A2.1-restricted CEA-specific CTLs,protecting nude mice more significantly from human CEA-expressing colon tumor challenge when adoptively transferred.Mechanistic investigation indicated that intracellular expression of the fusion protein empowered the transfected DCs by activation of STAT1 possibly via inducing IFN-βand ERK pathways.Therefore,the more potent ability to induce anti-CEA CTL responses enables the DCs,which transfected with recombinant adenovirus expressing the fusion gene of antigenic CEA fragment and Th1 adjuvant,as an alternative promising approach for the immunotherapy of CEA-positive tumors.Shuxun Liu Lin Yi Ma Ling Jinxia Jiang Lijun Song Juan Liu Xuetao Cao 2018Cellular & Molecular Immunology2018,15,2:2

5The E3 ubiquitin ligase NEDD4-1 protects against acetaminophen-induced liver injury by targeting VDAC1 for degradation显示文摘Acetaminophen(APAP)overdose is a major cause of liver injury.Neural precursor cell expressed developmentally downregulated 4—1(NEDD4-1)is an E3 ubiquitin ligase that has been implicated in the pathogenesis of numerous liver diseases;however,its role in APAP-induced liver injury(AILI)is unclear.Thus,this study aimed to investigate the role of NEDD4-1 in the pathogenesis of AILI.We found that NEDD4-1 was dramatically downregulated in response to APAP treatment in mouse livers and isolated mouse hepatocytes.Hepatocyte-specific NEDD4-1 knockout exacerbated APAP-induced mitochondrial damage and the resultant hepatocyte necrosis and liver injury,while hepatocyte-specific NEDD4-1 overexpression mitigated these pathological events both in vivo and in vitro.Additionally,hepatocyte NEDD4-1 deficiency led to marked accumulation of voltage-dependent anion channel 1(VDAC1)and increased VDAC1 oligomerization.Furthermore,VDAC1 knockdown alleviated AILI and weakened the exacerbation of AILI caused by hepatocyte NEDD4-1 deficiency.Mechanistically,NEDD4-1 was found to interact with the PPTY motif of VDAC1 through its WW domain and regulate K48-linked ubiquitination and degradation of VDAC1.Our present study indicates that NEDD4-1 is a suppressor of AILI and functions by regulating the degradation of VDAC1.Yiwei Zhu Lin Lei Xinghui Wang Linfang Chen Wei Li Jinxia Li Chenchen Zhao Xiliang Du Yuxiang Song Wenwen Gao Guowen Liu Xinwei Li 2023Acta Pharmaceutica Sinica B2023,13,4:1

7Effects of V and Al on Microstructure and Room Temperature Fracture Toughness of Nb-Si In-situ Composites显示文摘The effect of alloying elements V and Al on microstructure and room temperature fracture toughness of an experimental Nb-Si in-situ composite was investigated. The Nb-Si alloys with different amount of V and Al were prepared by non-consumable arc-melting furnace. The experimental results showed that with the addition of V and Al, the microstructure of the Nb-Si materials transformed from Nbss+Nb3Si to Nbss+Nb5Si3 and the lattice parameters of Nbss phase decreased, and the alloying element V promoted the formation of the finer Nbss structure. It was observed that the room temperature fracture toughness was improved by the addition of V and Al, and the optimum room-temperature fracture toughness of the material appeared in the alloy with 2.6at.%V and 3.6at.%Al. The improvement of room temperature fracture toughness may be mainly attributed to the increment of the volume fraction of Nbss phase and the decrement of the silicide phase size.Kang Yongwang Qu Shiyu Song Jinxia Han Yafang 2009稀有金属材料与工程2009,38,A03:1
8PtZn nanoparticles supported on porous nitrogen-doped carbon nanofibers as highly stable electrocatalysts for oxygen reduction reaction显示文摘The oxygen reduction reaction(ORR)electrocatalytic activity of Pt-based catalysts can be significantly improved by supporting Pt and its alloy nanoparticles(NPs)on a porous carbon support with large surface area.However,such catalysts are often obtained by constructing porous carbon support followed by depositing Pt and its alloy NPs inside the pores,in which the migration and agglomeration of Pt NPs are inevitable under harsh operating conditions owing to the relatively weak interaction between NPs and carbon support.Here we develop a facile electrospinning strategy to in-situ prepare small-sized PtZn NPs supported on porous nitrogen-doped carbon nanofibers.Electrochemical results demonstrate that the as-prepared PtZn alloy catalyst exhibits excellent initial ORR activity with a half-wave potential(E_(1/2))of 0.911 V versus reversible hydrogen electrode(vs.RHE)and enhanced durability with only decreasing 11 mV after 30,000 potential cycles,compared to a more significant drop of 24 mV in E_(1/2)of Pt/C catalysts(after 10,000 potential cycling).Such a desirable performance is ascribed to the created triple-phase reaction boundary assisted by the evaporation of Zn and strengthened interaction between nanoparticles and the carbon support,inhibiting the migration and aggregation of NPs during the ORR.Lei Zhao Jinxia Jiang Shuhao Xiao Zhao Li Junjie Wang Xinxin Wei Qingquan Kong Jun Song Chen Rui Wu 2023Nano Materials Science2023,5,3:0
9In-situ construction of Li4Ti5O12/rutile TiO2 heterostructured nanorods for robust and high-power lithium storage显示文摘Li4Ti5O12 is considered as a safe and stable anode material for high-power lithium-ion batteries due to its“zero-strain”characteristic during the charge/discharge.However,the intrinsically low electronic conductivity leads to a deterioration in highrate performance,impeding its intensive application.Herein,the Li4Ti5O12/rutile TiO2(LTO/RT)heterostructured nanorods with tunable oxide phases have been in-situ fabricated by annealing the electrospun nanofiber precursor.By constructing such a heterostructured interface,the as-prepared sample delivers a high capacity of 160.3 mAh·g–1 at 1 C after 200 cycles,125.5 mAh·g–1 at 10 C after 500 cycles and a superior capacity retention of 90.3%after 1,000 cycles at 30 C,outperforming the heterostructure-free counterparts of pure LTO,RT and the commercial LTO product.Density Functional Theory calculation suggests a possible synergistic effect of the LTO/RT interface that would improve the electronic conductivity and Li-ion diffusion.Yiguang Zhou Shuhao Xiao Jinxia Jiang Rui Wu Xiaobin Niu Jun Song Chen 2023Nano Research2023,16,1:0

11Tailoring the interactions of heterostructured Ni_(4)N/Ni_(3)ZnC_(0.7)for efficient CO_(2)electroreduction显示文摘Electrocatalytic CO_(2)reduction into CO has been regarded as one of the most promising strategies for sustainable carbon cycles at ambient conditions,but still faces challenges to achieve both high product selectivity and large current density.Here,we report a Ni_(4)N/Ni_(3)ZnC_(0.7)heterostructured electrocatalyst embedded in accordion-like N-doped carbon through a simple molten salt annealing strategy.The optimal Ni_(4)N/Ni_(3)ZnC_(0.7)electrocatalyst achieves a high CO Faraday efficiency of 92.3%and a large total current density of-15.8 m A cm^(-2)at-0.8 V versus reversible hydrogen electrode,together with a long-term stability about 30 h.Density functional theory results reveal that the energy barrier for*COOH intermediate formation largely decreased on Ni_(4)N/Ni_(3)ZnC_(0.7)heterostructure compared with Ni_(4)N and Ni_(3)ZnC_(0.7),thus giving rise to enhanced activity and selectivity.A rechargeable Zn-CO_(2)battery is further assembled with Ni_(4)N/Ni_(3)ZnC_(0.7)catalyst as the cathode,which shows a maximum power density of 0.85 mW cm^(-2)and excellent stability.Junjie Wang Zhao Li Zhaozhao Zhu Jinxia Jiang Yulan Li Jinju Chen Xiaobin Niu Jun Song Chen Rui Wu 2022Journal of Energy Chemistry2022,,12:0

13Stabilizing highly active atomically dispersed NiN_(4)Cl sites by Cl-doping for CO_(2)electroreduction显示文摘Nickel-nitrogen-carbon single-atom catalysts have attracted widespread interest for CO_(2)electroreduction but they suffer from poor stability.Herein,we report on the preparation of Cl-and N-doped porous carbon nanosheets with atomically dispersed NiN_(4)Cl active sites(NiN_(4)Cl-ClNC)through a molten-salt-assisted pyrolysis strategy.The optimized NiN_(4)Cl-ClNC catalyst delivers exceptional CO_(2)conversion activity with outstanding stability for over 220 h at−0.7 V versus RHE and a high CO Faradaic efficiency of 98.7%at a CO partial current density of 12.4 mA cm^(−2).Moreover,NiN_(4)Cl-ClNC displays a remarkable CO partial current density of approximately 349.4 mA cm^(−2)in flow-cell,meeting the requirements of industrial applications.Operando attenuated total reflectance surface-enhanced infrared absorption spectroscopy and density functional theory calculations are used to understand the outstanding activity and stability.Results reveal that the introduced axial Ni-Cl bond on the Ni center and Cl─C bond on the carbon support synergetically induce electronic delocalization,which not only stabilizes Ni against leaching but also facilitates the formation of the COOH*intermediate that is found to be the rate-determining step.Zhao Li Xueqiang Qi Junjie Wang Zhaozhao Zhu Jinxia Jiang Xiaobin Niu Andreu Cabot Jun Song Chen Rui Wu 2023SusMat2023,3,4:0
14Platinum nickel alloy-MXene catalyst with inverse opal structure for enhanced hydrogen evolution in both acidic and alkaline solutions显示文摘The development of an efficient Pt-based electrocatalyst in acidic and alkaline electrolytes is of great significance to the field of electrocatalytic hydrogen evolution.Herein,we report a strategy for in situ growth of Pt_(3)Ni truncated octahedrons on Ti3C2Tx nanosheets and then obtain an ordered porous catalyst via a template method.Meanwhile,we use the finite element calculation to clarify the relationship between the component structure and performance and find that the performance of the spherical shell microstructure catalyst is higher than that of the disc structure catalyst,which is also verified by experiments.The experimental analysis shows that the ordered porous catalyst is conducive to enhancing electrocatalytic hydrogen evolution activity in acidic and alkaline electrolytes.In an acidic solution,the overpotential is 25 mV(10 mA·cm^(−2)),and the Tafel slope is 22.86 mV·dec−1.In an alkaline solution,the overpotential is 44.1 mV(10 mA·cm^(−2)),and the Tafel slope is 39.06 mV·dec−1.The synergistic coupling between Ti3C2Tx and Pt_(3)Ni nanoparticles improves the stability of the catalyst.The in situ growth strategy and design of microstructure with its correlation with catalytic performance represent critical steps toward the rational synthesis of catalysts with excellent catalytic activity.Wei kong Lihong Li Xiaoxia Yu Zhongyuan Xiang Yawei Cao Muhammad Tahir Zehua Lu Jinxia Deng Yanlin Song 2023Nano Research2023,16,1:0
15Effect of Zr and Ti on isothermal oxidation behavior of Nb–Si based alloys显示文摘The isothermal oxidation behavior of 56Nb-16Si-(20-x)Ti–3Cr–3Al-2Hf-xZr(x?0,2,5,10 at.%)alloys was investigated at 800℃ and 1250℃,respectively.The results show that increasing the Zr content evidently increased the oxidation rates at 800℃,accompanied by the obvious occurrence of pesting oxidation.The alloys showed alike linear oxidation kinetics at 1250℃.With the increase of Zr content,the adherence and integrity of oxide scales were improved,but the overall oxidation resistance was slightly deteriorated.The observed oxidation behavior may be attributed to the composition variation of Zr and Ti in the alloys.The oxidation mechanism associated with the composition variation is discussed in this study.Ankang Sun Ziqiang Dong Shuang Yang Jintao Shu Yanjie Liu Yi Liu Yongwang Kang Dinggang Wang Jinxia Song 2022Progress in Natural Science:Materials International2022,32,2:0
