From Molecular Motion to Macroscopic Function: Tailoring Tetraarylethylene Supramolecular Architectures for Aggregation‐Induced Emission and Wave Absorption

Rare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Integrating light emission and electromagnetic wave (EMW) absorption into a single material opens up possibilities for multienvironmental applications. Herein, we propose a novel “molecular engineering‐pyrolysis conversion” strategy to construct a bifunctional system with tunable photoluminescence and efficient EMW absorption performance.

550kV SF₆ GIS用母线罐体电磁感应分析研究

Gaoya dianqi, 2007
对550kV/4000A SF6 GIS用母线多点接地与单点接地系统中额定运行条件下不同罐体材料、不同壁厚罐体上感应电流、感应电流形成的损耗功率及其阻抗特性进行了分析计算;比较了接地方式、罐体材料及罐体壁厚对损耗功率及母线阻抗特性的影响。分析结果表明:在多点接地系统中,当罐体材料为铝材和不锈钢材时罐体损耗功率随罐体壁厚的增大而减小,罐体材料为锅炉钢时罐体损耗功率几乎不随罐体壁厚变化而变化,当罐体材料为不锈钢材和锅炉钢时的损耗功率分别是罐体材料为铝材时损耗功率的14倍和32倍。在单点接地系统中 ...

Improving the Electrochemical Properties of SiOx/Graphite Anode for High‐Performance Lithium‐Ion Batteries by Ultrathin Lithium Film Prelithiation

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT High‐capacity SiOx/graphite (SiO/G) anodes offer great potential for advancing lithium‐ion battery technology; however, their practical application is limited by low initial coulombic efficiency (ICE) and rapid capacity decay. These challenges primarily arise from unstable phase transitions and the formation of the solid electrolyte interphase
