The influence of ultrasonic cavitation on plasma discharge in a liquid medium and the properties of thus-produced nanoparticles

Abstract

The basic principles of the formation of plasma discharge in a liquid under exposure to ultrasonic cavitation are reviewed. The laboratory equipment produced for this purpose is described. The results of studies of discharges in liquids under the action of intensive ultrasound vibrations above the cavitation threshold are presented. The difference in the characteristics between discharges before and after the beginning of cavitation is substantiated. The difference in the physicochemical and optical properties of metal oxide nanoparticles synthesized in a discharge before and after the beginning of cavitation is demonstrated.
