Microdischarges formed in conductive liquids represent highly complex physical and chemical environments. The aim of this project is to develop a better understanding of these systems through an active combination of experimental measurements and numerical simulations. Building on the insights of the first period, a variety of optical and electrical diagnostics will be applied to microdischarges formed in contact with Al, Mg and W electrodes, in order to better understand the influence of the surface material on discharge formation. In addition to the direct insights derived from these measurements, they will be used to provide inputs to specially constructed 0D simulations of microdischarges formed in liquids, which will provide insights into the plasma-chemical kinetics taking place.
