Plasma-liquid interactions

In the ‘Plasma–Liquid Interactions’ Special Topic Collection, researchers explore the richness and full breadth of plasma– liquid interactions and their applications. The collection contains two perspective articles that discuss key questions related to fundamental processes at the plasma–liquid interface. Researchers introduce the concept of plasma-driven solution electro chemistry (PDSE) inspired by comparing plasma–liquid interactions with conventional electrolysis and develop ten questions that should be answered to enable researchers to make transformational advances in plasma–liquid interactions for a variety of applications. The Perspective by Vanraes and Bogaert focuses on that same plasma–liquid interface but emphasizes the gas phase processes rather than liquid-phase processes.
