Liquid Water at Interfaces: New Insights From Molecular Scale Studies

Speaker: Ian C. Bourg, Earth Sciences Division, Lawrence Berkeley National Laboratory
Series: CEE Departmental Seminars
Location: Friend Center 006
Date/Time: Thursday, April 3, 2014, 4:30 p.m. - 6:00 p.m.


IanInterfaces involving liquid water (water-solid, water-air, water-hydrocarbon) are ubiquitous in the geosphere. They also play important roles in many water and wastewater treatment operations. An abiding question in the study of these interfaces is the manner in which the properties of interfacial water differ from those of bulk liquid water. This talk discusses new insights into the properties of liquid water at interfaces and the relevance of these insights to studies of adsorption and precipitation, molecular diffusion, interfacial redox reactions, colloidal aggregation, multiphase flow in porous media, dissolution of gases in groundwater, methane emissions from lake sediments, and cloud droplet nucleation.


Dr. Bourg holds B.Eng. and M.Sc. degrees in Chemical Engineering from the National Institute of Applied Sciences in Toulouse, France, and a Ph.D. in Civil and Environmental Engineering from the University of California at Berkeley. In 2009, he joined the Lawrence Berkeley National Laboratory as a career-track Scientist. Since 2011, he has been on the executive committee of the Center for Nanoscale Control of Geologic CO2, a DOE-supported Energy Frontiers Research Center. His research aims to develop a fundamental understanding of liquid water at interfaces. At the present time, his group is using atomistic and continuum scale modeling techniques to probe the properties of natural and engineered clay barriers, the nanoscience of geologic carbon sequestration, and the molecular basis of kinetic isotope effects. He has published a textbook and 18 peer?reviewed articles or book chapters.
