This week, Through the Gates host Jim Shanahan is joined by Trevor Douglas, the Earl Blough Professor of Chemistry in the IU Bloomington College of Arts and Sciences’ Department of Chemistry. Douglas is part of a research team working toward a material that may eventually fuel cheap, efficient cars that run on water — work being funded by the U.S. Department of Energy. The team has created an efficient biomaterial that catalyzes the formation of hydrogen — one half of the “holy grail” of splitting H2O. Also on this episode, we’ll hear from California-based author Dana Johnson, an associate professor of English at the University of Southern California, who talks about her writing process and reads an excerpt from one of her novels. Johnson will be in town next week as a faculty member at the annual IU Writers’ Conference (June 4-8).
