Engineering Smart Elastic Interfaces
Friday, January 20
Noon – 1:00 PM
Surfactants, polymers, and nanoparticles can be engineered to exert active control over a wide variety of interfacial systems, however the mechanisms by which this occurs are still only partially understood. For example, complexation, association, and reaction in these materials at fluid-fluid interfaces leads to the formation of networks which confer properties such as mechanical rigidity that are outside the description provided by equilibrium surface thermodynamics. We describe experimental approaches and accompanying frameworks based on two-dimensional continuum mechanics to characterize the intrinsic properties of these systems and discuss applications of smart interfaces in tissue engineering, dispersion stabilization, and adhesion modification.
Bio: James Ferri is the James T. Marcus ’50 Professor of Chemical and Biomolecular Engineering. He is a frequent guest and visiting fellow at the Max Planck Institute for Colloids and Interfaces in Potsdam, Germany, as well as in the Department of Chemistry and CSGI, University of Florence, and the Chinese Academy of Science in Beijing and Suzhou. His research focuses on the stability of disperse systems, smart nanomaterials, and interfacial phenomena in materials. He has received awards from the Alexander von Humboldt and Camille and Henry Dreyfus Foundation, as well as from a number of other international institutions. He received his BS and PhD both in Chemical Engineering from Johns Hopkins in 1995 and 2000.
