Stimulants caveat study

There are numerous applications to chemical engineering research currently under study in several laboratories in the United States and Europe, and the author hopes that this review will stimulate even more research. Microparticle chemical reaction studies are in their infancy, and there is much to be learned at the level of the single particle because internal diffusion can be eliminated as a rate-controlling process. Reactions at elevated temperatures are possible with the caveat that there is an upper limit above which charge-loss accelerates.
