High energy ball milling process for nanomaterial synthesis

Besides materials synthesis, high-energy ball milling is a way of modifying the conditions in which chemical reactions usually take place either by changing the reactivity of as-milled solids (mechanical activation — increasing reaction rates, lowering reaction temperature of the ground powders)—or by inducing chemical reactions during milling (mechanochemistry). It is, furthermore, a way of inducing
