The process of copper nanostructure formation on a silicon dioxide substrate was simulated using the molecular dynamics method. The process parameters corresponded to the conditions in a low-pressure gas-discharge plasma. The relationship between the nanostructure formation rate and the main plasma parameters was determined.

Using the molecular dynamics method, the sputtering of a copper target and the subsequent formation of a copper nanofilm on a silicon substrate has been modeled. The process parameters corresponded to the conditions in low-pressure gas-discharge plasma. The obtained values of the sputtering coefficient are consistent with experimental data. The nanofilm growth rate has been determined. [ABSTRACT FROM AUTHOR]

Electrophysical parameters of atmospheric pressure discharge with an aqueous potassium permanganate solution as a cathode have been determined. The cathode potential drop, the electric field strength in the positive column of the discharge, and the current density depending on the solution concentration and the discharge current have been found, as well as the emission coefficient γ.

The kinetics of the processes of simultaneous reduction of Cr(VI) and degradation of phenol during the treatment of their aqueous solutions with different initial concentrations using an atmosphericpressure air direct-current discharge have been studied. The solution served as the discharge cathode. It has been shown that the discharge treatment leads to a decrease in the concentration of both Cr(VI) and phenol. Phenol additives accelerate the Cr(VI) reduction process and make it irreversible. The phenol degradation and Cr(VI) reduction kinetics are described well ( R > 0.99) by the pseudo-first-order rate equation in phenol and Cr(VI) concentrations, respectively. The apparent rate constants of the processes have been determined, the energy efficiency of the processes has been evaluated, and possible mechanisms of the proceeding reactions have been discussed.

A new method is proposed for the synthesis of powdered zinc oxide with the use of a plasma-solution system. The chemical and phase compositions and the morphology of the synthesized powders have been determined. It has been found that the calcination of powders obtained in the plasma-solution system leads to the formation of ZnO. [ABSTRACT FROM AUTHOR]
