Regulation the electronic density of solid-state electrolyte by donor–acceptor(D–A)system can achieve highly-selective Li^(+)transportation and conduction in solid-state Li metal *** study reports a high-performance solid-state electrolyte thorough D–A-linked covalent organic frameworks(COFs)based on intramolecular charge transfer *** other reported COFbased solid-state electrolyte,the developed concept with D–A-linked COFs not only achieves electronic modulation to promote highly-selective Li^(+)migration and inhibit Li dendrite,but also offers a crucial opportunity to understand the role of electronic density in solid-state Li metal *** introduced strong electronegativity F-based ligand in COF electrolyte results in highlyselective Li^(+)(transference number 0.83),high ionic conductivity(6.7×10^(-4)S cm^(−1)),excellent cyclic ability(1000 h)in Li metal symmetric cell and high-capacity retention in Li/LiFePO_(4)cell(90.8%for 300 cycles at 5C)than substituted C-and N-based *** is ascribed to outstanding D–A interaction between donor porphyrin and acceptor F atoms,which effectively expedites electron transferring from porphyrin to F-based ligand and enhances Li^(+)***,we anticipate that this work creates insight into the strategy for accelerating Li^(+)conduction in high-performance solid-state Li metal batteries through D–A system.

Optical enhancement effects of plasmonic nanostructures on organic photovoltaic cells

引用

Chinese Chemical Letters 2015年第4期26卷 419-425页

作者： Hui Joon Park L.jay guo Division of Energy Systems Research Ajou University Department of Electrical Engineering and Computer Science University of Michigan

In this article, the optical enhancement effects of plasmonic nanostructures on OPV cells were reviewed as an effective way to resolve the mismatch problems between the short exciton diffusion length in organic semiconductors （around 10 nm） and the large thickness required to fully absorb sunlight （e.g. hundreds of nanometers）. Especially, the performances of OPVs with plasmonic nanoparticles in photoactive and buffer layers and with periodic nanostructures were investigated. Furthermore, nanoimprint lithography-based nanofabrication processes that can easily control the dimension and uniformity of structures for large-area and uniform I^lasmonic nanostructures were demonstrated.

APEX2- tagging of Sigma 1-receptor indicates subcellular protein topology with cytosolic N-terminus and ER luminal C-terminus

作者： Timur Mavylutov Xi Chen Lianwang guo jay yang Department of Anesthesiology University of Wisconsin SMPH Madison Wl 53705 USA Department of Surgery and Physiology & Cell Biology Ohio State University Columbus OH 43210 USA

Dear Editor, Deciphering the role of any protein in a cell requires knowl- edge of the structure, subcellular localization, and the topological orientation of the protein within the relevant cells. The Sigma-1 receptor （S1R） largely localized to the endo- plasmic reticulum （ER） serves as a pluripotent intracellular signaling molecule with diverse roles in the cell including ion channel modulation, stress signaling, and transcriptional regulation （reviewed in Suet al., 2016）, however, the basic topology of this protein within a cell remains controversial.

Ni-catalyzed cross-electrophile alkyl-alkyl coupling reactions

引用

Science China Chemistry 2025年

作者： Li-Xu you Lan Tian Chun-Ling guo Shun-Xi Li yu-Cheng Liu yu-Long Li Wei Shu College of Chemistry and Environmental Engineering Key Laboratory of Green Catalysis of Higher Education Institutes of Sichuan Sichuan University of Science and Engineering Guangming Advanced Research Institute Shenzhen Grubbs Institute Department of Chemistry and Guangdong Provincial Key Laboratory of Catalysis Southern University of Science and Technology

Introducing saturated carbon-carbon bonds into organic molecules significantly increases the three-dimensional configuration,thus altering the physical and chemical properties as well as the functions of molecules. Transition-metal-catalyzed carboncarbon cross-couplings represent one of the most straightforward, efficient and modular alternatives to build saturation in a single step. However, the efficient construction of alkyl-alkyl bonds remains a formidable challenge due to the precise manipulation of multiple alkyl metallic intermediates as well as associated competitive side reactions and selectivity control. Over the past years, Ni-catalyzed cross-coupling under reductive conditions has gained more and more attention for alkyl-alkyl crosscoupling partially attributing to the low-valent state of metal centers under reducing conditions, which suppresses the competitive β-hydride elimination process, thus facilitating the formation of alkyl-alkyl bonds. In this review, the initiative and progress of Ni-catalyzed cross-electrophile alkyl-alkyl cross-coupling, including the efforts in racemic and enantioselective formation of alkyl-alkyl bonds, have been summarized and discussed. Moreover, the challenges and further opportunities in this area have also been discussed.

Microstructure and Properties of WC-Co/NiCrBSi Brazing Coating

Journal of Materials Science & Technology 1999年第3期15卷 283-285页

作者： Lu, SP guo, y Chen, LS Acad Sinica Inst Met Res Shenyang 110015 Peoples R China

Through rolling technology, a flexible metal cloth consisting of metal powder (NiCrBSi powder or WC-Co powder) and organism in a certain ratio were made, which could be used as brazing coating raw materials. WC-Co/NiCrBSi wear coating was fabricated through high temperature vacuum brazing after the flexible metal clothes were assembled on 42CrMo steel surface. The tensile strengths of coating self and coating/matrix approached to 100 similar to 140 MPa and 300 similar to 360 MPa, respectively, at different brazing parameters. Effect of Co on the wear property of the coating was analyzed. The abrasive wear property of WC-Co/NiCrBSi brazing coating is better than WC-17Co/NiCrBSi flame overlaying and CoCrW overlaying.
