“…Electrical discharges are used in various industrial processes such as, for example, surface modifications [1], sterilization [2], noxious compound decomposition [3], micro-and nanostructures synthesis [4][5][6], plasma etching and electrical-discharge machining [7], or flue gas cleaning [8]. For these processes, various forms of electrical discharges at both polarities are used: glow, streamers, or arc discharges.…”
