“…spectroscopic measurement. On the other hand, the striations have already been observed in previous studies using various atmospheric pressure plasmas, such as glow discharges, [24][25][26] microwave-excited discharges, 27) hollow cathode plasmas, 28) and asymmetric barrier discharges. 29) In previous APPJ studies, the striation phenomena were also reported.…”

The formation of multiple stationary striations between a nozzle exit and a conductive target plate was clearly observed at regular intervals using a digital camera along an atmospheric pressure plasma jet of dielectric barrier discharge using a neon gas into ambient air. From the results of measuring using a high-speed camera during the positive current phase, the emission initially started in the middle between the nozzle and the target, and striations progressed in both upward and downward directions. During the negative current phase, the emission initially started in a region near the target, and the striations rapidly progressed to the nozzle.

“…Recently, these structures have also been observed at atmospheric pressure in glow discharges [7][8][9], microwave excited discharges [10], hollow cathode plasmas [11], and plasma jets [12,13]. In particular, the longitudinal stratification of filaments in an atmosphericpressure rf plasma jet in argon has been detected in relation to a self-organization effect in Ref.…”

Striated microdischarges in an asymmetric barrier discharge in argon at atmospheric pressure

et al. 2011

The investigation of striated microdischarges in barrier discharges in argon at atmospheric pressure is reported. Microdischarges were investigated by means of electrical measurements correlated with intensified CCD camera imaging. The scaling law theory known from low-pressure glow discharge diagnostics was applied in order to describe and explain this phenomenon. The investigated microdischarge is characterized as a transient atmospheric-pressure glow discharge with a stratified column. It can be described by similarity parameters i/r≈0.13 A/cm, pr≈5 Torr cm, and 3<λ/r<5 with the current i, pressure p, interval of subsequent striations λ, and radius of the plasma channel r. An attempt to describe the mechanism of creation of a striated structure is given, based on an established model of the spatial electron relaxation.

“…The mixture of fullerenes extracted from soot is mostly C60 (about 90%) and C70 (about 10%), and the content of higher fullerenes is very small [6]. The rate of formation of fullerenes in the arc process, and hence their quantitative yield, is influenced by many factors, in particular, such as: type of buffer gas and its pressure [7], electrical characteristics of the arc and the nature of its binding to the anode [8], plasma temperature and concentration of electrons in it [9], the conditions for the removal of carbon vapor from the arc zone and its further condensation [10].…”

Fullerenes production by electric arc pyrolysis of methane in an AC three-phase plasma torch

et al. 2019

The article deals with a high-voltage three-phase AC plasma torch working as a part of a plasma-chemical facility. The plasma torch consists of three electric arc channels and three rod copper electrodes. The initial breakdown occurs with high voltage (10 kV) provided by a high voltage power supply. The electric arc plasma oxygen-free pyrolysis of methane was realized on the facility. The fullerenecontaining fraction was extracted from the carbonaceous material by extraction with orthoxylene. The produced carbon-black and the selected extract were analyzed by modern methods of physical and chemical analysis: scanning electron microscopy, X-ray phase analysis, IR spectroscopy.
