Dr Mario Nappa

USA: The lead chemist in the development of the HFO refrigerant R1234yf has been recognised for his efforts by The Chemists’ Club.

Dr Mario Nappa of Chemours has been named the winner of this year’s Winthrop-Sears Medal for entrepreneurial achievement.

Since joining DuPont in 1981, Dr Nappa has been an inventor on 140 patents and has received numerous medals and awards. He is currently a Chemours Fellow responsible for developing the company’s fluorine based r&d product portfolio.
