Mechanochemistry is a rather less developed field of chemistry where reactions are driven not by thermal energy, electrons or photons but rather by mechanical strain, which can lower the activation energy needed to be overcome for bond cleavage. This strain can, for example, be applied in a ball mill. Heterogeneous catalysts can also lower the ...
