DuPont Scientist Receives University Citation
Thursday 07. February 2008 - Mark Shiflett, a researcher at the DuPont Experimental Station in Wilmington, Del., recently received the 2007 Presidential Citation for Outstanding Achievement from the University of Delaware.
The award honors University of Delaware (UD) graduates of the last 20 years who exhibit great promise in their professional career and/or public service activities.
Mark received his master’s degree in chemical engineering and a doctorate from UD in 1998 and 2002, respectively. He and his research team at DuPont developed new refrigerant mixtures to replace the CFCs (chlorofluorocarbons) and HCFCs (hydrochlorofluorocarbons) that were linked to the depletion of the Earth’s ozone layer. The new refrigerant mixtures are non-ozone depleting, as well as nonflammable, with low toxicity and good thermal stability.
