Development of Cold Plasma Technologies for Surface Decontamination of Seed Fungal Pathogens: Present Status and Perspectives

“…An electric discharge with DC or AC as a power source can be used to generate this type of plasma. The most common types of DC discharges are corona discharge (when the current range is 10 −7 –10 −5 A), glow discharge (current range 10 −5 –1 A), and arc discharge (when the applied current is bigger than 1 A) [ 31 ]. The best known and most commonly used AC discharge, with the advantage of operating at atmospheric pressure, is the dielectric barrier discharge (DBD), in which the two electrodes are covered by an insulating dielectric barrier [ 32 ].…”

“…Two types of electrical configuration can be used: capacitively coupled (CC) or inductively coupled (IC). The latter can be carried out as an “electrodeless discharge”, since the electrodes can be placed outside the plasma chamber, thus eliminating contamination of plasma by the electrode materials [ 31 ]. An example of RF-generated plasma system is presented in Figure 1 .…”

On the plasma and electrode erosion processes in spark discharge nanoparticle generators

“…are perfectly in line with the well-known peculiarities of series RLC circuits[106]. However, these results have important consequences on SDGs.…”

“…Due to the underdamped behavior of the system (c.f. criterion is held, and the current waveform can be described by the following equation [106]:…”

Generation and Characterization of an Atmospheric-Pressure Plasma Jet (APPJ) and Its Application in the Surface Modification of Polyethylene Terephthalate

“…In this method, four suitable lines (two for Ar I and two for Ar II) were chosen from spectral lines of argon obtained from the discharge. The working formula used to calculate the electron temperature is as follows [18,19].…”
