SUMMARY:Clays in contact with water\, ions and CO2: interfacial properties
  and hydrodynamics on the molecular scale - Benjamin Rotenberg\, Universit
 e Pierre et Marie Curie

DESCRIPTION:Clays are ubiquitous minerals which play an important role in 
 a number of environmental and industrial contexts\, such as the geological
  disposal of radioactive waste or carbon dioxide sequestration. In both ca
 ses\, one must be able to predict how mobile species will be transported t
 hrough and retained by these porous materials. This requires a detailed un
 derstanding of the processes at play at the interface between the mineral 
 and the pore fluids\, including wetting\, electrostatics or hydrodynamics.
  In this talk\, I will describe some contributions of molecular simulation
 s to the field. These include insights into the questions of the swelling/
 shrikage of clay particles in contact with a CO2 reservoir\, the wetting o
 f external surfaces by CO2 or water and the validity of continuous hydrody
 namic descriptions in clay nanopores.
