Grinding chemistry The Chemical Institute of Canada

A member of McGill University’s chemistry department, Friscic’s interest was piqued during post-doctoral work with William Jones at the Pfizer Institute for Pharmaceutical Materials in the United Kingdom. This was where he learned that grinding molecules together can promote hydrogen bond associations without the need for a solvent or catalyst.
