| 2 | Constructing electron-blocking grain boundaries in garnet to suppress lithium dendrite growth显示文摘Li_(7)La_(3)Zr_(2)O_(12)(LLZO)is considered as a promising solid-state electrolyte due to its high ionic conductivity,wide electrochemical window,and excellent electrochemical stability.However,its application in solid-state lithium metal batteries(SSLMBs)is impeded by the growth of lithium dendrites in LLZO due to some reasons such as its high electronic conductivity.In this study,lithium fluoride(LiF)was introduced into Ta-doped LLZO(LLZTO)to modify its grain boundaries to enhance the performance of SSLMBs.A nanoscale LiF layer was uniformly coated on the LLZTO grains,creating a threedimensional continuous electron-blocking network at the grain boundaries.Benefiting from the electronic insulator LiF and the special structure of the modified LLZTO,the symmetric cells based on LLZO achieved a high critical current density(CCD)of 1.1 mA·cm^(-2)(in capacity-constant mode)and maintained stability over 2000 h at 0.3 mA·cm^(-2).Moreover,the full cells combined with a LiFePO_(4)(LFP)cathode,demonstrated excellent cycling performance,retaining 97.1% of capacity retention after 500 cycles at 0.5 C.Therefore,this work provides a facile and effective approach for preparing a modified electrolyte suitable for high-performance SSLMBs. | Xing Xiang Zecheng Fang Congkun Du Zhenzhen Zhao Jiajia Chen Yanhua Zhang Huihu Wang Chenhuinan Wei Fei Chen Qiang Shen | 2024 | Journal of Advanced Ceramics2024，13，2： | 0 |
| 3 | CaCO_(3)-MnSiO_(x)hybrid particles to enable CO_(2)-mediated combinational tumor therapy显示文摘Nanocatalysts mediated reactive oxygen species(ROS)based therapy has been exploited as an alternative therapeutic modality of tumor with high specificity and minimal side effects.However,the treatment outcome is limited by the efficiency of local catalytic reaction.Herein,we report a novel type of core–shell hybrid nanoparticles(CaCO_(3)@MS),consisting of CaCO_(3)and MnSiO_(x),for synergistic tumor inhibition combining enhanced catalytic effect and calcium overload.In this system,MnSiO_(x)serves as catalysts with glutathione(GSH)responsive Mn^(2+)ions release functionality.CaCO_(3)nanoparticles play three important roles,including carbon dioxide(CO_(2))donor,pH modulator,and Ca^(2+)overload agent.It is found that the CaCO_(3)nanoparticles can induce CO_(2)production and pH increase in acidic tumor environment,both of which promote Mn^(2+)mediated ROS generation.And simultaneous release of Ca^(2+)ions from CaCO_(3)triggers calcium overload in tumor,which functions collaboratively with excessive ROS to induce cancer cell apoptosis.The results demonstrate that after treatment with CaCO_(3)@MS,a remarkable tumor inhibition was achieved both in vitro and in vivo,while no clear toxic effect was observed.This study has therefore provided a feasible effective approach to improve catalytic therapeutic efficacy by an“exogenous CO_(2)delivery”strategy for combinational tumor therapy. | Congkun Xie Tian Zhang Yike Fu Gaorong Han Xiang Li | 2022 | Nano Research2022，15，9： | 0 |
| 4 | Evaluation of the Land Development Suitability in the Typical Provincial Boundary Regions Based on GIS Technology显示文摘To undertake the transfer of industry to promote the industry and its optimization of land use configuration as the research background,a typical provincial boundary region in Chuzhou City of eastern Anhui region was selected as an example from as two perspectives of resource constraint and development guidance.Land development suitability evaluation index system was constructed by using GIS spatial data mining,analysis,output display and other functions,panel data with 90×17 were formatted.multi-factor comprehensive evaluation method and logic quadrant model were used to complete the Chuzhou domain land development suitability evaluation,and the differentiated land use zoning countermeasures were proposed.The results show that priority development region covering the county area adjacent to town and surrounding area is the regional socio-economic development of better concentrated area;reserve development region focus on most of Tianchang,north Mingguang,south Quanjiao and other regions,other areas of sporadic distribution;restricted development area mainly distributed in Dingyuan and Fengyang plain area,as well as hilly area at the junction,and of Mingguang and Lai'an;coordinately development of region is the only district and the surrounding township,as well as towns including Dingcheng,Louqiang and Liuzhen. | Shuping FAN Congkun CHENG Sike XIANG Hongmei ZHANG Dong WANG | 2013 | Asian Agricultural Research2013，5，11： | 0 |
