Extending a Battery's Lifetime with Heat

10-03-15

The research of alumnus Asghar Aryanfar (’15 PhD, ME) along with Professors Goddard and Hoffmann has shown that heat can break down the damaging branch-like structures that grow inside batteries, which may possibly be used to extend battery lifetimes. [Learn more] [Read the paper]

New Insight into Acid Rain Chemistry

06-13-12

A multidisciplinary team led by Dr. A. J. Colussi, comprising of graduate student Himanshu Mishra, and Professor Michael Hoffmann along with Dr. Robert J. Nielsen and Professor William A. Goddard III from the Materials and Process Simulation Center, has shown that the dissociation of nitric acid on thin layers of water, such as those in contact with air or biological membranes, is dramatically different from the similar process inside water. They have found that the molecules of nitric acid do not dissociate when they collide with water unless its surface contains at least 1 anion per million water. This work explains how minute concentrations of anions might subtly participate in acid rain chemistry, the cycling of nitrogen oxide pollutants on urban haze, and in the charging of protein surfaces that drive enzyme activities.
