Plasma discharges are traditionally associated with a gaseous phase; however, discharges can be generated in all phases. Plasma discharges formed in liquids and interfacing with liquids represent an emerging and fast-growing field of research, not the least because they offer unique conditions that enable decontamination of pathogens, synthesis of nanostructures, and treatment of contaminated water. With the variety of discharge regimes and types of liquids comes a rich field of multiphase phenomena to be discovered, measured, modeled, and utilized. In this Special Topic, we explore this richness of relatively unexplored phenomena.
