Be sure to bring your ID to the final. No final will be accepted without an ID! No exceptions. The review session is on Sunday at 2PM in room 225 CB. I want to call to your attention that Scott Martin and I joined the faculty this year. Scott is an excellent analytical chemist who works in bioanalytical and environmental chemistry. His research interests can be found at http://www.uiowa.edu/~chemdept/research/faculty/martin/index.ht ml We are both setting up our labs and would welcome undergraduates to do research with us. Feel free to contact Scott or myself about these opportunities. Lecture 41, 12/13/02, page #1
