The Geochemistry and Interfacial Sciences Group (formerly Aqueous Chemistry & Geochemistry) investigates fundamental and applied aspects of the interaction of fluids (aqueous; non-aqueous) with solids (natural; engineered) across a wide range of length and time scales. The primary focus of this research is to reach a predictive level of understanding of fluid-mediated processes in complex natural and technological systems through unique capabilities for experiments including but not limited to neutron scattering from ambient conditions to high temperatures and pressures, coupled with molecular-level and descriptive modeling of system properties and behavior. Group expertise and capabilities impact our understanding of extractive separations, energy production and utilization, environmental remediation, fluid behavior in Enhanced Geothermal Systems (EGS) and ultrasupercritcal steam generation, petroleum and gas resources, and geological CO2 sequestration. The multidisciplinary nature of the group is exemplified in the diverse set of research areas currently being addressed:
