Chemist Explores Earth’s Atmosphere, Mars

In a wide-ranging lecture on February 7, Dr. Joseph S. Francisco, past president of the American Chemical Society and a professor of chemistry and earth & atmospheric science at Purdue University, discussed chemical findings related to the destruction of the ozone layer, the creation of alternatives to harmful Chlorofluorocarbons, and the possibility of earlier life on Mars.

Titled, “From Earth’s Atmosphere to Planetary Engineering of Mars: An Adventure in Chemistry,” Francisco’s talk was the inaugural Lillian L.Y. Wang Yin, Ph.D. Endowed Lecture in Chemistry.

Francisco described the chemistry of the processes of the earth’s ozone destruction by chlorofluorocarbons and research into the design of environmentally benign materials to replace these harmful materials. The talk also discussed planetary engineering and new chemistry exploration on Mars.
