Non-Equilibrium Plasma–Water Interactions: Experimental and Theoretical Approaches

Abstract: Nitrogen is essential for industry and agriculture, but converting abundant atmospheric nitrogen into reactive forms requires signifi cant energy. Intermittent renewable energy sources (e.g., wind and solar) can power non-equilibrium plasma sources, which effi ciently generate nitrogen- and oxygen-based reactive species (RONS). One common way to produce such reactive plasmas is through streamer–spark discharges, initiated by strong electric fi elds from nanosecond/microsecond pulsed high-voltage power sources. These discharges can operate in direct contact with the liquid surface, thus creating and storing RONS in so-called plasma-activated water (PAW). In the agri-food sector, PAW offers a wide range of possible applications (e.g. suppression of bacterial activity or nutrient solution for plants in hydroponic systems).

This seminar aims to, in two parts, provide an overview of experimental and numerical modeling approaches, both aimed at optimizing RONS generation in non-equilibrium plasmas and enhancing their incorporation into plasma-activated water.
