Title: Fluids Confined in Nanoporous Materials: Adsorption, Transport and Thermal Conductivity
Institut Néel, Room E424 (Louis Weil)
Abstract: Nanoporous materials are at the heart of numerous important applications: adsorption (gas sensing, drug delivery, chromatography), energy (hydrogen storage, fuel cells and batteries), environment (phase separation, water treatment, nuclear waste storage), Earth science (exchange between the soil and the atmosphere), etc. In this talk, I will present the state-of-the-art on adsorption and transport in nanoporous materials which possess pore sizes spanning several orders of magnitude (from the sub-nm scale to a few tens of nm). We will see that simple statistical mechanis modeling allows rationalizing the different thermodynamic and transport regimes observed when confining fluids in such nanoporous materials. Finally, I will also discuss how fluid adsorption in nanoporous materials leads to a decrease in the solid thermal conductivity through the so-called rattle effec
