| Research Abstract |
We investigated the phenomena at plasma-liquid interface with nanometer scale interactions theoretically and experimentally, using atmospheric pressure dc glow discharge with liquid electrode. We found that electron/positive ion irradiation from plasma to liquid surface induced variety of redox reactions in liquid by changing not only charged species but also liquid composition and gas condition experimentally. As an application of reactions at plasma-liquid interface, we demonstrated magnetic particle generation (magnetite) as well as Au and Ag nanoparticle generation in liquid. Numerical simulation of glow discharge with liquid electrode was carried out by considering the transport and reactions of charged and active species both in plasma and in liquid with Poisson's equation. The effect of low energy ion irradiation to liquid surface on water molecule kinetics was investigated by classical molecular dynamics simulation.
