Thermal energy storage（TES） solutions offer opportunities to reduce energy consumption, greenhouse gas emissions, and cost. Specifically, they can help reduce the peak load and address the intermittency of renewable energy sources by time shifting the load, which are critical toward zero energy buildings. Thermochemical materials（TCMs） as a class of TES undergo a solid–gas reversible chemical reaction with water vapor to store and release energy with high storage capacities(600 k Wh m-3) and negligible selfdischarge that makes them uniquely suited as compact, stand-alone units for daily or seasonal storage. However, TCMs suffer from instabilities at the material（salt particles） and reactor level（packed beds of salt）, resulting in poor multi-cycle efficiency and high-levelized cost of storage. In this study, a model is developed to predict the pulverization limit or Rcritof various salt hydrates during thermal cycling. This is critical as it provides design rules to make mechanically stable TCM composites as well as enables the use of more energy-efficient manufacturing process（solid-state mixing） to make the composites. The model is experimentally validated on multiple TCM salt hydrates with different water content, and effect of Rcriton hydration and dehydration kinetics is also investigated.

将菠菜和花生酱经辐射后再食用是不是很新奇呢？实际上，利用X射线、伽马射线或电子光束对密封加工的食品进行辐射可以起到杀菌、消毒的作用。美国已允许对菠菜、卷心莴苣等部分食品进行辐射处理，最近食品与药物总局又向联邦政府提出申请要求对热狗、熟肉等更多食品进行辐射消毒。尽管对这样的做法仍然存在一些反对意见，但是笔者认为，这不失为一种解决食品安全问题的好方法。
