Atmospheric pressure plasmas in contact with liquid have been utilized as a source of reactive nitrogen and oxygen species (RONS). When we contact plasma to liquid, it forms complex reaction network by the inhomogeneous distributed short-lived RONS at the plasma-liquid interface. Therefore, the spatiotemporal distribution of short-lived RONS can be extremely challenging to understand.
In this study, we have been trying to build a new experimental method using a plasma-exposed high-speed liquid flow (~ 10 m/s) system to detect the short-lived RONS decay in experiments. In order to explain this experimental decay, we also built the reaction model which is based on the NxOy reaction.
