Using tandem in situ monitoring and isotope-labeled solids, we reveal that mechanochemical ball-milling overcomes inherently slow solid-state diffusion through continuous comminution growth of milled particles. This process occurs with or without a net chemical reaction also between solids liquid additives can be practically used for highly efficient deuterium labeling solids. The presented findings fundamental aspect milling reactions delineate methodology should considered the study mechanisms.
