Ionic liquids (ILs) can be used to replace one or more phases in conventional oil/water emulsions including Pickering emulsions-surfactant-free emulsions which utilize nanoor micron-sized particles to stabilize the immiscible liquid-liquid interface. Due to the extreme tunability of both the ILs and particles used, the study of IL-based Pickering emulsions yields novel emulsion morphologies and insights into the ionic liquid-liquid-particle interactions present. This work discusses extensive

... erimental work on IL-based Pickering emulsions and IL/liquid interfaces, emphasizing unique phenomena-such as "bridging" between emulsion droplets and spontaneous particle transport across the interface-never observed in more conventional Pickering emulsions. Molecular dynamics (MD) simulations of particles at the IL/liquid interface are also discussed, and fundamental insights from these simulations are used to enhance understanding of the unique interface behavior revealed by experiment.
