| Fluids including hydrocarbons, aqueous solutions, and gaseous species (e.g. CO2, CH4) can occupy the pores or fractures within solid matrices. The size, distribution and connectivity of these confined geometries, the chemistry of the solid, the chemistry of the fluids and their physical properties collectively dictate how fluids migrate into and through these micro- and nano-environments, wet and ultimately react with the solid surfaces. The purpose of this project is to demonstrate the application of state-of-the-art experimental, analytical and computational tools to assess key features of the fluid-matrix interaction. Our multidisciplinary approach combines neutron and X-ray scattering experiments, FTIR and NMR spectroscopies, molecular dynamics simulations, and thermodynamic measurements to quantitatively assess molecular properties of fluids confined to well-characterized porous media, subjected to a wide range of experimental conditions. These studies are providing a molecular-level understanding of how intrinsically different fluids behave in confined geometries compared to bulk systems. |
