Chemiresistors: Direct Translation of Selective Molecular Interactions to Electrical Signals - Olin 149, 3:30-4:30pm
Join Professor Tim Swager for his second presentation. The ultimate chemiresistor is a wire that spans two electrodes and ordinarily carries charges with ease, but binding of a target molecule of interest (an analyte) prevents transport and, in effect, breaks a molecular circuit. Such single wire sensors remain elusive to make reproducibly, but using this concept as a goal has helped to guide his research in this area.
Goodsell Observatory Open House - 9:30-11:30pm
Resident astronomers and astronomy students will be on hand to facilitate viewing of the sky and galactic objects we can see from our location, using historical and modern telescopes.
