Congrats to Robert Mayer for winning the prize for best oral presentation at the REGIO Symposium in Freiburg-im-Breisgau, Germany. The REGIO Symposium is an annual tri-national conference on organic chemistry held jointly between the universities in the lower Rhine region (Freiburg, Basel, Strasbourg and Mulhouse). Roberts’ talk was on how metals influence the reactivity of coenzymes in the absence of enzymes. Well done!
