Clays are used as barriers for the isolation of landfills and contaminated sites. They are envisioned as long-term storage media for hazardous materials and radioactive wastes, and as seals in the case of geological CO2 sequestration or energy storage. Clay properties greatly influence the integrity, efficiency, and safety of these applications. Natural and Engineered Clay Barriers provides a clear view of the fundamental properties of clay materials and how these properties affect their engineering applications. This volume focuses on how the mass transfer properties (hydraulic permeability, gas fluxes, molecular diffusion, semi-permeable membrane properties), geochemical reactivity (adsorption, dissolution) and mechanical properties of clay barriers at the macroscale are influenced by phenomena that occur at clay mineral - water interfaces. * Examines clay properties from the molecular to the macroscopic scale* Addresses experimental and modeling issues* Authored by experts in the properties of clay barriersÜber den Autor:
Ian Bourg received his bachelor's degree in Industrial Process Engineering from the National Institute of Applied Sciences in Toulouse (France) in 1999. He received his doctorate in Civil and Environmental Engineering from the University of California at Berkeley in 2004. He was a postdoctoral fellow at the University of Chicago and a career-track Scientist at the Lawrence Berkeley National Laboratory. In 2015, he joined the Department of Civil and Environmental Engineering at Princeton University as an Assistant Professor. 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. The goal of Dr. Bourg's research is to develop a fundamental understanding of the properties of water at interfaces. At the present time, his group is using atomistic and continuum modeling techniques to probe the nanoscience of geologic carbon sequestration, the aquatic geochemistry of nanoporous media (clay interlayers, nanoporous silica), and the molecular scale origins of kinetic isotope effects.
