1Porous LiF layer fabricated by a facile chemical method toward dendrite-free lithium metal anode显示文摘Lithium metal is supposed to be critical material for constructing next-generation batteries due to extremely high capacity and ultralow redox potential. However, the perplexing issue of lithium dendrite growth impedes the commercial application. The initial nucleation and low Li ions diffusion rate in the electrolyte/electrode interface dominate the deposition behavior. Therefore, a uniform and flexible interface is urgently needed. Here, a facile method is proposed to prepare a thin and porous LiF-rich layer (TPL) by the in-situ reaction of small amount of ammonium hydrogen difluoride (NH4HF2) and Li metal. The deposition morphology on Li metal anode with LiF layer is significantly flat and homogeneous owning to low lateral diffusion barrier on LiF crystals and the porous structure of TPL film. Additionally, the symmetrical cells made with such TPL Li anodes show significantly stable cycling over 100 cycles at high current density of 6 mA/cm^2. The TPL Li|LiFePO4 full cells keep over 99% capacity retention after 100 cycles at 2.0 C. This approach serves as a facile and controllable way of adjusting the protective layer on Li metal.Yanxia Yuan Feng Wu Guanghai Chen Ying Bai Chuan Wu 2019Journal of Energy Chemistry2019,28,10:14
2Construction of cDNA library from iron-deficiency induced maize roots and screening and identification of iron-stress gene Fdr3显示文摘To isolate Fe-deficient related (Fdr) genes, an expression cDNA library of 4.5×105 pfu/μg has been constructed from maize roots in iron-stress. 6 clones have been screened from the cDNA library by differential hybridization screening. It is proved that an Fdr3 cDNA clone expressed stronger under iron-deficient condition than under iron-sufficient one by Northern blot and Western blot.YIN Liping QI Xiaoting LIU Xianglin HUO Chunyan BAI Yanxia QIU Zesheng ZHANG Fusuo 2000Chinese Science Bulletin2000,45,12:4

7Space Weather Service for Chinese Space Science Satellites显示文摘Strategic Priority Research Program on Space Science has gained remarkable achievements. Space Environment Prediction Center(SEPC) affiliated with the National Space Science Center(NSSC) has been providing space weather services and helps secure space missions. Presently, SEPC is capable to offer a variety of space weather services covering many phases of space science missions including planning, design, launch,and orbital operation. The service packages consist of space weather forecasts, warnings, and effect analysis that can be utilized to avoid potential space weather hazard or reduce the damage caused by space storms,space radiation exposure for example. Extensive solar storms that occurred over Chinese Ghost Festival(CGF)in September 2017 led to a large enhancement of the solar energetic particle flux at 1 AU, which affected the near Earth radiation environment and brought great threat to orbiting satellites. Based on the space weather service by SEPC, satellite ground support groups collaborating with the space Tracking, Telemetering and Command system(TT&C) team were able to take immediate measures to react to the CGF solar storm event.LIU Siqing ZHONG Qiuzhen GONG Jiancun SHI Liqin CHEN Dong MIAO Juan CAI Yanxia BAI Meng MA Wenzhen LI Zhitao LIU Fanghua CHEN Yanhong 2018空间科学学报2018,38,5:0
8Solvent Effects on Kinetics and Electrochemical Performances of Rechargeable Aluminum Batteries显示文摘The rechargeable aluminum batteries(RAB)have shown great potential for energy storage applications due to their low-cost and superior volumetric capacity.However,the battery performances are far from satisfactory owing to the poor kinetics of electrode reactions,including the solid-state ionic diffusion and interfacial charge transfer.The charge transfer reaction,typically the cation desolvation at the interface(Helmholtz plane),is crucial for determining the interfacial charge transfer,which induces the solvent effect in batteries but has not been explored in RABs.Herein,we provide a comprehensive understanding of solvent effects on interface kinetics and electrochemical performance of RAB by analyzing the desolvation process and charge transfer energy barrier.The pivotal role of solvent effects is confirmed by the successful application of Al(OTF)_(3)-H_(2)O electrolyte,which displays easy desolvation,low charge transfer resistance,and thus superior Al-ion storage performance over other electrolytes in our studies.In addition,based on the strong correlation between the calculated desolvation energy and charge transfer energy barrier,the calculation of dissociation energy of ion-solvent complex is demonstrated as an efficient index for designing electrolytes.The in-depth understanding of solvent effects provides rational guidance for new electrolyte and RAB design.Sichen Gu Yang Haoyi Yanxia Yuan Yaning Gao Na Zhu Feng Wu Ying Bai Chuan Wu 2022Energy Material Advances2022,,1:0
