Nonequilibrium Liquid Plasma Generation

In most cases, the electric breakdown of liquids is initiated by the application of high electric field on the electrode, followed by rapid propagation and branching of plasma channels. Typically, plasmas are only considered to exist through the ionization of gases, and typical production of plasmas in liquids has generated bubbles through heating or via cavitations and sustains the plasmas within those bubbles. The question appears: Is it possible to ionize the liquid without cracking and voids formation? We have demonstrated possibility of formation of nonequilibrium plasma in liquid phase and investigated the dynamics of excitation and quenching of nonequilibrium plasma in liquid water.
