The Structure and Dynamics of Patterned Liquid Salts

In contrast with other common liquids, Ionic Liquids (ILs) have symmetries and patterns on multiple length scales. They are mainly characterized by positive-negative charge alternation but also by the alternation between the charge networks and apolar pockets or domains. Both structure and transport properties are highly heterogeneous on the nanoscale. For example, one can find regions of high and low local friction and laws of transport such as the Stokes-Einstein equation often fail for solutes dissolved in them. Molten salts are in some way similar but in others very different. These systems can also have multiple scale organizational patterns, but these are more complex. The talk will attempt to carefully walk us through these concepts with particular emphasis on making connections with X-ray and neutron scattering experiments.

Bio: Claudio Margulis received his undergraduate degree from the University of Buenos Aires in Argentina and later his Ph.D. in Chemistry from the group of David Coker at Boston University working on non-adiabatic quantum dynamics. He later did postdoctoral work at Columbia University working with Bruce Berne on a variety of different areas ranging from the hydrophobic collapse to excited state chemistry. He was hired by the University of Iowa in 2003 as an Assistant Professor and became a full Professor in 2015. Dr. Margulis is a Kavli Fellow and a recipient of the NSF CAREER Award among other honors. His research is on theory of liquids with particular emphasis on ionic systems such as “Ionic Liquids” and “High-Temperature Molten Salts”.
