Because the mechanism requires the reacting species to have significantly different diffusion rates, only a few liquid phase chemical reaction systems exhibiting the phenomenon have been discovered. In solids the situation is markedly different, since species such as impurities or other defects typically have diffusivities $\\propto\\!\\exp\\left( -E/k_{\\rm B} T\\right)$, w","authors_text":"M.R.
