Dynamics of Multi‐component Fluids near Interfaces

Friday, April 12 @ 10:30 am - 11:30 am EDT

Speaker: Sepideh Razavi, University of Oklahoma.

Abstract: Presence of complex solutions composed of fluids, ions, surfactant molecules, and colloidal particles is commonplace in problems relevant to materials discovery and manufacturing. Such multicomponent fluidic systems are often confined by interfaces in processes associated with the water-energy nexus as well, for example, in membrane separations and subsurface energy recovery and storage. To make matters more intricate, fluid interfaces are not static and are constantly subject to external disturbances such as thermal gradients, imposed stresses, and changes in composition. Given the environmental and economic impact of the subject matter, it is important to advance our fundamental quantitative understanding of the complex interfacial systems just summarized, with the goal of ultimately predicting and controlling their behavior in relevant hightech applications. In this presentation, I will review recent findings in our group on how particle attributes such as wettability and surface anisotropy influence the stability and rheology of fluid interfaces. I will discuss the impact of particle surface properties on the interfacial microstructure and flow behavior, and their connection to the performance in resulting Pickering foams.
