Curved interfaces—bubbles, droplets, and pores—are a significant challenge in chemical engineering. The majority of conventional modeling tools (e.g., equations of state) are only valid for bulk systems, i.e., those of large volumes and negligible interfacial curvature. Multicomponent, multiphase systems with interfacial curvature exist across many applications, including CO2 storage in subsurface reservoirs, cloud formation in the atmosphere, pharmaceutical drug development, and food and beverage production. Additionally, whether a colloid remains stable with time or whether the constituents separate is determined by the tendency of the dispersed phase to aggregate or coalesce. Depending on the interfacial curvature, key variables such as vapor pressure and freezing point can deviate from those expected for bulk systems (i.e., with infinite radii of curvature). Thus, understanding and controlling interfacial properties is important.
