Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT With the growing severity of volatile organic compounds (VOCs) pollution, metal‐organic frameworks (MOFs)‐derived materials offer a promising solution through efficient photothermal catalysis. In this paper, M‐MnOx (M = Cu, Ni, Co, Fe) catalysts derived from manganese‐based MOFs were successfully prepared by the sacrificial template method and

Jianzhu Gangjiegou Jinzhan, 2021 为研究K形偏心支撑半刚性连接钢框架的抗震性能,采用较低屈服点的可替换耗能梁段作为耗能单元,对一个单层单跨平面内钢框架模型进行低周循环加载试验。通过试验分析了框架的变形特性、塑性发展情况及破坏模式,分析了框架的强度、刚度、滞回性能、耗能特性。在连接节点处的高强螺栓上粘贴应变片,并观察高强螺栓的应变发展情况。试验结果表明:破坏主要发生在耗能梁处且耗能梁先于框架屈服并消耗能量;梁柱节点处在加载过程中始终没有屈曲破坏;由于框架梁和耗能梁在加载过程中的相互错动,造成滞回曲线出现捏缩效果,高强螺栓出现松动。

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.

Questa è una mini opera filosofico-scientifica che unisce riflessione e descrizione per esplorare l’origine, l’evoluzione e il destino dell’universo. Nasce dal desiderio di coniugare la profondità lirica della filosofia con la concretezza descrittiva della fisica, proponendo una nuova visione: l’universo non come frutto di perfezione, ma come ...
