“…8). Jang et al assume that electrical characteristics such as current density and applied voltage are the same with or without bubbles, which is unlikely and does not correlate with Shin's electrical data reported in [69]. As argon is introduced, the voltage decreases (from 2 kV without bubbling to about 1.4 kV with 100 sccm Ar) and the current increases.…”

Electrical discharges in liquids are used to synthesize and process nanoobjects with breakthrough achievements that lead to high expectations in the field. As plasmas are non-equilibrium media, the possibility to access novel compositions, shapes, structures, etc. is often put forward as major argument to promote these processes. Two main classes of processes are considered in this review: the so-called "solution plasma" and glow-discharge electrolysis. The influence of the main parameters controlling the selected processes is discussed. Applications are also presented together with expectations on breakthrough achievements awaited for these processes. Solution characteristics Electrical conductivityElectrical conductivity is generally the key factor that determines the applied voltage required for breakdown and discharge ignition. The lower the conductivity, the higher the voltage needed to achieve reproducible discharges, and the shorter the pulse width.

Discharges in liquids are very efficient to synthesize nanoparticles by electrode erosion. This simple process is only simple in appearance. Mechanisms responsible for the production of nanoparticles are several depending on the choice of process parameters. They determine size distributions, shapes, composition, and defects of produced particles. They also control their possible assembly into more complex structures. This article describes the basic physics of nanoparticles’ synthesis by discharges in liquids using electrodes and gives a summary of the research efforts that have been devoted to the understanding of this process. A special attention is paid to thermodynamics of these systems driven by discharges that are at or close to local equilibrium. Although a complete picture is not available yet, huge progress has been made and offers new capabilities for a better control of these kinds of processes. Finally, among important challenges that are still to tackle, the possibility of forming nanoalloys from immiscible elements or achieving unimodal monodisperse size distributions is questioned from the current mastery reached in this field.
