Abstract
Anomalous fluid flow, thermodynamics, and reactivity of confined fluids compared to bulk fluids have significant implications for storing and recovering fluids in the subsurface and engineered materials for sustainable energy and the environment. In this context, the fate of CO2 in nanoporous environments for subsurface CO2 storage, stability of ice hydrates and carbon-bearing hydrates in response to a changing climate, and storage of excess renewable methane in porous materials are closely linked to their organization in confinement which is a function of the fluid-solid interactions. Developing quantifiable insights on the structure of confined fluids is now possible due to advances in advanced X-ray and neutron scattering measurements, which can be used to validate molecular-scale predictions. Furthermore, operando investigations enable us to resolve temporal and spatial effects associated with the organization of confined fluids. This chapter introduces recent advances in harnessing scattering measurements and molecular-scale simulations to probe the organization of confined fluids in porous materials. The basic principles of X-ray and neutron scattering measurements and molecular-scale simulations are introduced, and case studies that harness these approaches are discussed. This chapter sheds fundamental insights into experimental and simulation approaches to resolving mesoscale and molecularscale phenomena associated with the organization of confined fluids.
