Rare Metals, EarlyView.ABSTRACT Developing low‐energy‐input electrocatalytic systems for efficient hydrogen production is crucial for advancing sustainable energy technologies. The overall hydrazine splitting (OHzS) has emerged as a promising strategy to reduce the overall energy consumption by replacing the sluggish oxygen evolution reaction.

Rare Metals, EarlyView.ABSTRACT Early detection of thermal runaway (TR) is essential for lithium‐ion battery (LIB) safety, as unchecked TR risks catastrophic failures in energy storage systems. Gas‐based sensing offers a faster and more direct approach by detecting decomposition products at the molecular level.

Gaoya dianqi实验室中常采用加速老化方法获得硅油的老化试样，并根据试样中溶解气体组分及体积分数判断硅绝缘油的老化状态，但当前实验中仅能施加热应力或电应力，不能较好地反映硅油的真实工况。为解决这这一问题，文中开展了电热应力对硅油产气特性协同效应的实验研究。文中针对PMX-200型硅油，在200 ℃、25 kV下设计了硅油的热电老化、电热老化和电热联合老化等3组加速老化实验，通过对试样中的气体组分及体积分数分析，发现热电老化方式与电热联合老化方式下试样中溶解气体组分及体积分数最为接近，误差在7.41%~16.86%之间 ...

Dianci bileiqi, 2013 为今后实现自然积污规律研究和防污的差异化,对污秽颗粒等效简化模型、大气总悬浮颗粒物（TSP）的粒径分布函数、绝缘表面污秽主要化学成分对应TSP的粒径分布进行了综述和分析,认为可以污秽颗粒可等效简化为球体,使用空气动力学粒径衡量其粒径;建立TSP粒径分布函数拟合模型;分析认为化学成分Ca2+、SO42-、Cl-、SiO2、Al2O3在TSP中的粒径主要分布在1.810μm,010μm,1.810μm,30-40μm,40μm50μm的范围内,最后对自然积污规律研究和防污的差异化进行了展望。
