Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT The urgent environmental crisis caused by polyethylene terephthalate (PET) waste necessitates efficient upcycling strategies. Herein, we establish a novel pathway to transform waste PET plastic into a high‐performance catalytic material for mediating the oxygen evolution reaction (OER). Through a one‐step hydrothermal process, waste PET serves

Dianci bileiqi, 2018 高压支柱瓷绝缘子的断裂会对电力系统的安全稳定运行带来严重威胁,而支柱瓷绝缘子的断裂事故在冬季低温环境中尤为多见。为分析低温环境下支柱瓷绝缘子的力学特性,建立了支柱瓷绝缘子的热-结构耦合有限元模型及胶装区域孔隙结冰膨胀的数值计算模型,计算分析了不同环境温度下、不同位置和不同程度结冰膨胀时的应力分布规律及相应的最小临界裂纹尺寸变化规律,研究表明:环境温度的降低、膨胀程度的增大可导致支柱瓷绝缘子所受的最大拉应力随之增大,最小临界裂纹尺寸则相应地逐渐减小 ...
