Natural and Engineered Clay Barriers: Volume 6

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.

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. Dr Faiza Annabi-Bergaya obtained a Licence-ès-Science in Physical-Chemistry from the University of Tunis in 1966, a first PhD in Inorganic Chemistry in 1971 from University La Sorbonne-Paris VI and a second PhD in Physics in 1978 from the University of Orleans (France). She started her career in 1971 at the CNRS from which she is presently Emeritus Research Director. Her research interest is focused on the Physics and Chemistry of clays and clay minerals. She is member of the AIPEA Nomenclature Committee. She was Secretary of the ECGA in 1999-2003. As President of the GFA (French Clay Group) in 2003-2007, she created the annual meetings of the GFA, organizing the first two meetings in Orleans. She launched the Series Developments in Clay Science with the publication in 2006 of Volume 1 (Handbook of Clay Science) and she is Series Editor since 2013. She is Editor-in-Chief of Applied Clay Science since 2012.
