It is shown that a new form of the plasma discharge with bulk glow throughout the space between electrodes and an descending current-voltage characteristic, occurring in liquid in an ultrasonic field with an intensity above the cavitation threshold, can be efficiently used to initiate the various physical and chemical processes. In such an acoustic plasma discharge, nanoparticles of oxides of various metals, i.e., aluminum, copper, tin, iron, titanium, indium, zinc, molybdenum, and others, are synthesized with controllable particle shape and size and narrow size distribution. Micrographs of some nanoparticles are presented. The difference in luminescence of particles produced in the absence and presence of cavitation is shown.

“…Chemical compositions, dimensions, morphologies, optical and other properties of these nanoparticles can be easily regulated by the plasma discharge parameters, materials of electrodes and liquids. In other works, it was demonstrated that ultrasonic cavitation itself is a promising way for modification of properties of solid nano-and microparticles [9][10][11][12][13][14][15][16].…”

In this study, plasma discharge in a liquid at intensive ultrasonic field above the cavitation threshold has been proven to be of great interest for initiation of various physical and chemical processes. In such discharge, nanoparticles of tungsten and zinc oxides have been synthesized. Further exploration of synthesized nanoparticles has demonstrated that the factor of ultrasonic cavitation during the synthesis substantially affects physical and chemical characteristics of nanoparticles.

“…Scanning and transmission electron microscopy analysis of these nanoparticles has shown that carbon fibers, nanotubes, plates etc. as well as metal oxide nanoparticles with peculiar physical properties could be obtained during the reaction [5][6][7][8][9][10][11][12]. Obtained nanoparticles and their agglomerates could be used also as filling material, colorants, components of composites etc.…”

The paper shows, that a low-temperature plasma initiated in liquid media in interelectrode discharge gap is able to decompose hydrogen containing organic molecules resulting in obtaining gaseous products with volume part of hydrogen higher than 90% (up to gas chromatography data). Tentative assessments of energy efficiency, calculated with regard for hydrogen and feedstock heating value and energy consumption, have shown efficiency factor of 60-70%, depending on the source mixture composition. Theoretical model calculations of discharge current and voltage have been performed; the values are in good accordance with experimental data.
