Garnet-type solid-state batteries(SSBs)are considered to be one of the most promising candidates to realize next-generation lithium metal batteries with high energy density and ***,the dendrite-induced short-circuit and the poor interfacial contact impeded the practical ***,interface engineering to achieve low interfacial resistance without high temperature calcination was developed,which Li_(6.4)La_(3)Zr_(1.4)Ta_(0.6)O_(12)(LLZTO)was simply coated with complex hydride(Li_(4)(BH_(4))_(3)I(3L1L))in various mass ratios n(Li_(4)(BH_(4))_(3)I)-(100−n)LLZTO(10≤n≤40).The interfacial conductivity increases by more than three orders of magnitude from 8.29×10^(−6)S·cm^(−1)to 1.10×10^(−2)S·cm^(−1).Symmetric Li cells exhibit a high critical current density(CCD)of 4.0 mA·cm^(−2) and an excellent cycling stability for 200 h at 4.0 mA·cm^(−2).SSBs with polymeric sulfur-polyacrylonitrile(SPAN)cathode achieve a high discharge capacity of 1149 mAh·g^(−1) with a capacity retention of 91%after 100 cycles(0.2 C).This attempt guides a simple yet efficient strategy for obtaining a stable Li/LLZTO interface,which would promote the development of solid-state batteries.

World Journal of Traditional Chinese Medicine 2024年第2期10卷 254-262页

作者： zhao-Han huang Yuan Fang Qi Yu tong Wang College of Traditional Chinese Medicine Beijing University of Chinese MedicineBeijingChina Shanghai Center for Women and Children's Health ShanghaiChina

Objective: Radix Bupleuri and Radix Paeoniae Alba are referred to as Chai-hu and Bai-Shao, respectively, in Chinese. We used molecular docking and network pharmacological approaches to explore the active components of this Chinese herb combination which is commonly used for treating Alzheimer's disease(AD), the Chai-hu and Bai-Shao pair(CBP). Materials and Methods: The active compounds and action targets of Chai-hu and Bai-Shao were identified in the Traditional Chinese Medicine Systems Pharmacology database, and the Therapeutic Target Database, Drug Bank, Gen Cards, Dis Ge NET, and Online Mendelian Inheritance in Man databases were used to identify therapeutic targets in patients with AD. To identify a common target of CBP in the treatment of AD, we used the Metascape tool to perform Gene Ontology function enrichment and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analyses. In addition, CBP-AD protein–protein interaction(PPI) and herb-component-target networks were created using Cytoscape 3.8.2. Molecular docking was verified using Auto Dock tools. Results: We identified 20 active compounds of CBP, 202 active targets, 1,323 disease targets, and 117 active compound disease intersection targets;the PPI network showed that the top eight key targets were AKT1, interleukin(IL) 6, JUN, MAPK1, tumor necrosis factor, TP53, vascular endothelial growth factor, and epidermal growth factor. These act mainly on the fluid shear stress, atherosclerosis, IL-17, hypoxia-inducible factor-1, and nonalcoholic fatty liver disease pathways, among others, which control immune inflammation, cell proliferation, and apoptosis. Based on molecular docking results, the active components of CBP bind well to its key targets. Conclusion: Our results indicated that CBP was effective for treating AD by reducing the expression of inflammatory factors, promoting cell proliferation and differentiation, and preventing nerve cell death and anti-neuronal cell apoptosis.

Study on the mechanism and law of temperature,humidity and moisture content on the mechanical properties of molded fiber products

引用

Journal of Bioresources and Bioproducts 2024年第3期9卷 351-368页

作者： Zhiqiang Fu tong zhao hu Wang Jingyi Wei Haozhe Liu Liying Duan Yan Wang Ruixiang Yan School of Light Industry Science and Engineering Tianjin University of Science and TechnologyTianjin 300457China Department of Transportation and Vehicle Engineering Tangshan UniversityTangshan 063000HebeiChina College of Mechanical Engineering Tianjin University of Science and TechnologyTianjin 300457China

The change of temperature, humidity and moisture content (MC) will lead to the change of mechanical properties of molded fiber products (MFP). However, it is difficult to decouple the effects of temperature, humidity and MC on the mechanical properties of MFP, and predict the mechanical properties of MFP during the use. In this study, the laws and mechanism of mechanical properties of MFP with ambient temperature, humidity and MC were studied. The results showed that the direct effect of temperature (20−70 °C) on mechanical properties of MFP was insignificant, and the mechanical properties of MFP were mainly changed by MC. The MC was related to ambient temperature and humidity, and the relationship between the three could be described by the modified Guggenheim-Anderson-de Boer (GAB) model (20−70 °C and 30 %–90 % relative humidity). With the increase of MC, the elastic modulus and fracture strain was increased and decreased linearly, the yield strength and failure strength were presented GaussAmp laws, and the failure strain was presented asymptotic regressed distribution law. Two fracture modes of MFP, brittle fracture and ductile fracture, were revealed by the scanning electron microscopy of the mesoscopic fiber structure of sugarcane bagasse molded fiber products. The mathematical models and the changes of fiber structure were verified by wheat straw molded fiber products and waste paper molded fiber products. This study was contributed to understand the effects and mechanism of the change of temperature, humidity and MC on the mechanical properties of MFP.

Advanced oxidation via the synergy of C-defective/C-O band modified ultrathin porous g-C3N4 and PMS for efficient photothermal degradation of bisphenol pollutants and lignin derivatives

引用

Green Energy & Environment 2024年第7期9卷 1159-1170页

作者： Liquan Jing Meng Xie Yuanguo Xu Chun tong Xia Du Heng zhao Na Zhong huaming Li Jinguang hu School of Chemistry and Chemical Engineering Jiangsu University Department of Chemical and Petroleum Engineering University of Calgary School of Pharmacy Jiangsu University School of Material Science & Chemical Engineering Harbin University of Science and Technology Institute for Energy Research Jiangsu University

This work uses thermal polymerization of urea nitrate, oxyacetic acid and urea as the raw material to prepare ultra-thin porous carbon nitride with carbon defects and C-O band（OA-UN-CN）. Density functional theory（DFT） calculations showed OA-UN-CN had narrower band gap,faster electron transport and a new internal construction electric field. Additionally, the prepared OA-UN-CN significantly enhanced photocatalytic activation of peroxymonosulfate（PMS） due to enhanced light absorption performance and faster electron overflow. As the result, the OA-UN-CN/PMS could entirely degrade bisphenol A（BPA） within 30 min, where the photodegradation rate was 81.8 and 7.9 times higher than that of g-C3N4and OA-UN-CN, respectively. Beyond, the OA-UN-CN/PMS could likewise degrade other bisphenol pollutants and sodium lignosulfonate efficiently. We suggested possible photocatalytic degradation pathways accordingly and explored the toxicity of its degradation products. This work provides a new idea on the development of advanced photocatalytic oxidation processes for the treatment of bisphenol pollutants and lignin derivatives, via a metal-free photothermal-catalyst.
