Description
Like many other soft materials, foam displays complex fluid behavior. Under different circumstances it may behave like an elastic solid or a typical fluid depending on driving forces and the interactions between individual bubbles. To understand the inherent complexities of foam flow, an effective method to visualize its internal structure and dynamics is paramount. In this talk, I will introduce two techniques we have used in our lab to probe foam dynamics at the bubble level: optical tomography and confocal microscopy. The results show great promise to unveil the internal mechanisms that lead to the complex fluid behavior of foams.
Presenter Bio
Klebert Feitosa Assistant Professor, Physics & Astronomy, James Madison University
Dr. Feitosa received his Ph.D. from the University of Massachusetts Amherst. Prior to joining the faculty of the Physics and Astronomy Department at James Madison University in the summer of 2010, he worked as a postdoctorate at the University of Pennsylvania in the department of Physics and Astronomy and the department of Chemical and Biomolecular Engineering. He also worked for one year as a Staff Scientist for GlaxoSmithKline in the area of pre-clinical development. Over the years he has studied granular fluids, the glassy dynamics of soft materials, and the use of nanocarriers for drug delivery. His current research interests are in the emerging area of soft materials and complex fluids.
