Special features of a multichannel discharge in a porous solid cathode

Characterization of a DC-driven microplasma between a capillary tube and water surface

“…New chemical pathways that are not achievable with traditional plasma processes may be possible by microplasma-produced species at relatively low gas temperatures. Among all kinds of non-equilibrium plasma systems [7][8][9][10], underwater or on water discharges are interesting and promising for their value in plasma physics research [11][12][13][14][15][16][17][18][19][20][21][22][23] and applications in materials processing, biology, and water sterilization [5,[24][25][26]. A range of approaches for generating plasmas in/on liquids have been explored.…”

“…Several authors previously investigated discharge systems with electrolyte electrodes. These studies suggest that different modes, especially glow mode and multichannel mode could be ignited [11][12][13][14][15][16][17][18][19][20]. A mechanism of discharge maintenance based on the estimates of the average energy an impinging H + ion transfers to a negative ion of impurity in the electrolyte, was also proposed [11].…”
