Project Description

We are studying the behavior of bio-surfactants at the gas–water interface as a function of water pH and acidity and gas composition. The intern will work with Dr. Peng Zhang and Mr. Muzzamil Eatoo (Ph.D. student) build an experimental setup to probe the changes in surfactants behavior in real time.
