“…The experimental set‐up was designed to combine two types of discharges: APPJ, which based on dielectric barrier discharge, and a conventional spark discharge, the principle of which is described elsewhere. [ 27 ] The part of the experimental set‐up that presents an APPJ composed of a cylindrical quartz tube, on which two thin copper tapes are wound, is shown in Figure 1. These two tapes serve as APPJ electrodes.…”

This study demonstrates a method for the deposition of CuO x thin films by combining atmospheric pressure plasma jet with spark discharge. In this type of discharge source, the bulk copper material of spark discharge electrodes plays the role of a precursor. Copper atoms and particles go through the physical processes of sputtering, evaporation, and further agglomeration and condensation in the plasma jet and on the substrate. The experiments were carried out with and without a combination of discharges. The material coated on the substrate was studied using a scanning electron microscope, Raman spectroscopy, and energy-dispersive X-ray spectroscopy. The characteristics of the setup and plasma, such as I-V curves, optical emission spectra, and substrate temperature, were also measured. Copper electrodes were examined for erosion by a scanning electron microscope. The results demonstrate that deposits coated by combined discharge show denser and thicker films.

“…it limits the current flow into the system and almost uniformly distributes the discharge over the entire electrode area. Recently two main types of DBD designs have been proposed: volume barrier discharge (VBD), and surface barrier discharge (SBD) [4]. VBD consists of two parallel dielectric plates with electrodes mounted externally or two electrodes on one side of the dielectric.…”

Dielectric barrier discharge (DBD) is used for many important applications in various sectors of science and technology. For example, for ozone generation, surface modification of polymers, in plasma medicine, and for decomposition of heavy volatile organic compounds. Nowadays, one of the actual problems is getting of uniformity of discharge distribution for high quality treatment of materials surfaces. To achieve uniform distribution of the discharge, several methods are available, one is to use different types of noble gases, and another is to use AC power supply with frequency varied in wide range. But besides this, another of the potential methods for obtaining a uniformly distributed discharge is to blow through the discharge gap flow of air. This method was used in this paper to conduct experiments which consisted of oscilloscoping voltage and current values, high-speed imaging, also gas flow simulation for comparison with the experiments. The obtained results show the dynamics of microdischarge motion in laminar and turbulent flow regimes, which supported by flow simulation.

“…Plasma‐based techniques, such as plasma jets, spark discharges, and so forth, have been also applied in the production of nanomaterials. [ 7–10 ] Electrical discharge in liquid is an effective technique for nanomaterial synthesis, which is cost‐effective and ecological, and so it has great potential for use on the industrial level. [ 11–13 ] This technique basically relies on the ignition of a discharge between two electrodes immersed in a dielectric liquid.…”

Discharges in liquid hydrocarbons produce submicrometric particles with a graphitic shell. In this study, discharges are generated between two Cu electrodes immersed in various liquid hydrocarbons, and the produced particles are characterized by various techniques. The obtained results indicate that the thickness of the particle shell increases with increasing particle size; for instance, it is ~4 nm for small particles (~25 nm) and ~30 nm for large particles (~1 µm). Such variation in shell thickness is attributed to variations in the thermal properties of different‐size particles. On the basis of qualitative analysis, we assume that shell growth is induced by local pyrolysis (or pyrolysis‐like process) of the liquid hydrocarbon due to the ejection of hot particles from the electrodes.
