In Situ Uniform Lithium Enrichment for Dense, High‐Performance LLZO Solid Electrolytes
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT A major challenge in garnet‐type Li7La3Zr2O12 (LLZO) system all‐solid‐state electrolytes is the high porosity that typically remains after sintering, which compromises ionic conductivity and degrades battery cycling performance. To address this, we propose an innovative strategy to achieve uniform lithium enrichment on the surface of ...

Observation and Dynamical Analysis of Hydrographic Characteristics in the Pearl River Estuary in summer of 2015 [PDF]
, 2017 本文以实测CTD数据为基础，总结了2015年夏季珠江口海域及其冲淡水扩展路径上的水文特征。在结合遥感风场和定点浮标风场数据的基础上，分析了台风“莲花”影响下珠江口水体的温、盐度特征，以及珠江冲淡水扩展方式对于风场变化的响应情况。同时对航次过程中观测到的温度逆转现象的特征进行统计分析；并结合遥感数据对冲淡水影响区域的海表温度数据和叶绿素a浓度的分布特征进行研究。 2015年7月6日至17日珠江口航次CTD资料的分析表明：在香港的西南侧观测到相对的低温高盐中心；珠江口附近海域存在海水的垂向逆温现象 ...

Dynamic Linkage between Land-use and Water Quality in the Potomac River Basin and Its Management Implications [PDF]
, 2017 流域是一个具有特定结构和功能、相对独立完整的自然资源-生态环境-人类社会的复杂系统，承载了区域经济发展所需要的空间。人类及其他生物以其生活的流域作为物质依托，从中获取水、食物等物质资源和生活、娱乐、发展活动的空间资源。然而在社会经济高速发展的背景下，作为人类重要物质与空间依托的流域，其环境遭受来自各方面的多重影响因子的共同作用，其中以河流水质为主，正面临着日渐退化的趋势，因而保护人们赖以生存的环境迫在眉睫。很多人为因素包括城市化、农业活动、产业、污水排放都是影响河流水质的流域土地利用 ...
