UI's Vicki Grassian To Give Free Talk On Nanotechnology April 13

Vicki Grassian, professor of chemistry in the University of Iowa College of Liberal Arts and Sciences and professor of chemical and biochemical engineering in the College of Engineering, will deliver a free, public talk on nanotechnology from 5-6 p.m. Thursday, April 13 at the Cottage Bakery and Café, 14 S. Linn St. Her talk is titled, "Nanoscience and Nanotechnology:  When Size Really Matters."

Nanoscience is the study of the fundamental principles of molecules and structures with at least one dimension between 1 and 100 nanometers (one nanometer is 1 x 10-9 meter). Nanotechnology is the application of the unique properties of such objects to materials, devices and biological systems. Grassian, whose research in this area is supported by several federal funding agencies, is currently involved in a number of studies related to the environmental and health aspects of nanoscience and nanotechnology.

The talk is presented by Café Scientifique of Iowa City, a forum for debating  and discussing the latest ideas in science, mathematics, medicine and technology. The group is an international public outreach effort by scientists who are committed to promoting public engagement with science and making science accountable. The Web site for Café Scientifique is located at:
