Colloquium
Series 
Director's Special Colloquium
Surfaces science plays a central role in many chemical and physical processes, including those that bear directly on Argonne strategic initiatives like materials for energy, nanoscale research, energy storage and biological and environmental systems.

Geraldine L. Richmond, Professor of Chemistry at the University of Oregon, will discuss her research on macromolecular assembly at liquid surfaces at at a Director's Special Colloquium Tuesday, May 21.

Her talk, "Line 'Em All Up: Macromolecular Assembly at Liquid Surfaces" will begin at 10:30 a.m.in the Building 402 Auditorium. All employees whose schedules permit are invited to attend.

Shuttle Service available

Shuttle service will be provided for the Director’s Special Colloquium. There will be a continuous shuttle beginning at 9:45 a.m. with stops at 201, 212, 202, 240, 203, 208, 205 and 362. Return trips following colloquium.

Abstract:
A liquid surface provides a unique junction for the adsorption and assembly of charged macromolecular and polymeric materials. With their hydrophobic back- bones that coil and bend into a multitude of conformations, and the fickle hydrophilic functional groups whose characteristics can vary widely depending upon the aqueous phase composition, the molecular nature of their adsorption and assembly at a liquid surface is largely unknown. This presentation will describe our most recent spectroscopic studies of a variety of charged polymeric materials that assemble at aqueous surfaces. Topics to be discussed include factors that control their assembly, the effect of metal ion chelation on their assembly and how their behavior compares with similar but simpler molecular surfactant systems.

Biography:
Geraldine (Geri) Richmond is the Richard M. and Patricia H. Noyes Professor of Chemistry at the University of Oregon. Her research using laser spectroscopy and computational methods focuses on understanding the chemistry and physics that occurs at complex interfaces that have relevance to important problems in energy production, environmental remediation, atmospheric chemistry and biomolecular surfaces.

She is a member of the National Academy of Sciences, the American Academy of Arts and is a Fellow of the American Chemical Society the American Physical Society, the Association for Women in Science and the Society of Applied Spectroscopy.

Awards for her scientific accomplishments include the ACS Olin-Garvan Medal (1996), the Spiers Medal of the Royal Society of Chemistry (2004), the ACS Joel H. Hildebrand Award in Theoretical and Experimental Studies of Liquids (2011) and the APS Davisson-Germer Prize (2013).

She is the co-founder and Chair of COACh, a grass-roots organization that has helped in the career advancement of thousands of women scientists and engineers in the U.S., Asia, Africa and Latin America.
