Keith & Russ conduct a trans-Atlantic conversation with Sir John Meurig Thomas, a Welsh chemist and educator known for his work in heterogeneous catalysis, solid state chemistry, and surface & materials science. Sir John tells us about his fascinating start in science, and about his work in promoting "green" science; for example, producing niacin in a less environmentally-harmful or wasteful way.
