Using tandem in situ monitoring and isotope-labeled solids, we reveal that mechanochemical ball-milling overcomes inherently slow solid-state diffusion through continuous comminution and growth of milled particles. This process occurs with or without a net chemical reaction and also occurs between solids and liquid additives that can be practically used for highly efficient deuterium labeling of solids. The presented findings reveal a fundamental aspect of milling reactions and also delineate a methodology that should be considered in the study of mechanochemical reaction mechanisms.
通过串联原位监测和同位素标记固体，我们发现机械化学球磨通过对研磨颗粒的持续粉碎和生长克服了固有的缓慢固态扩散。该过程在有或没有净化学反应的情况下都会发生，并且在固体与液体添加剂之间也会发生，这实际上可用于固体的高效氘标记。所呈现的研究结果揭示了研磨反应的一个基本方面，也描绘了一种在机械化学反应机理研究中应予以考虑的方法。
