Geochemical reactions at mineral-water interfaces play a critical role in determining various micro- and macroscopic processes in natural environments, including contaminant transport, rock weathering, and change in porosity and permeability in porous media. Understanding these processes requires characterization of interfacial structure and reactivity at the molecular scale. This session will highlight recent experimental and computation research on geochemical interfacial systems covering from ideal single-crystal surfaces to complex environmental nanoparticles and porous media. The topics of interest in this session include, but are not limited to: (1) Surface structure and chemistry of minerals and nanoparticles; (2) Adsorption/desorption thermodynamics and kinetics; (3) Mineral dissolution and nucleation/growth; (4) Surface mediated redox reactions; (5) Multi-scale nature of mineral-water/rock-water interfaces in porous media; (6) Geochemical interfaces in extreme environments; (7) Development of new computational and experimental methods for interface research. We encourage contributions from a broad range of scientific disciplines that highlight advances in experimental, computational, and theoretical designs to bridge observations over a wide range of temporal and spatial scales.
