17 March 2016

Alexis St-Gelais – Popularization Our recent clarification about our usage of “synthetic” and “natural” to describe molecules shed light on one particular way to define synthetics, based on the origin of the building blocks (petroleum or fresh organic molecules from natural sources). We wanted to discuss this aspect further, since it is deeply tied to […]
