Electrical Characteristics of Atmospheric Air Corona Plasma by Multi-pin Electrodes

Influence of Multi‐Pin Anode Arrangement on Electric Field Distribution Characteristics and Its Application on Microgreen Seed Treatment

“…Therefore, the electric field stress around the tip of the pin anode has been lowered. [12,25,26] The increase in G P at the constant N P has increased the electric field stress at the tip of pin anode until the G P had a suitable distance after the electric field stress has slightly changed, [24] as shown in Table 1. This has happened, because the increase in G P has caused the equipotential lines and the electric flux similar to a www.advancedsciencenews.com www.pss-a.com single pin anode.…”

“…The density of the electric flux per equipotential line of a single pin anode has been increased, so the electric field stress around the tip of the pin anode has increased. [12,25,26] For this reason, the multi-pin anode with wide G P had higher electric field stress more than the narrow G P . Normally, the corona discharge is easily generated by non-uniform electric field around 30 kV cm À1 electric field stress, which could be found in a single pin anode and multi-pin anode with wide G P .…”

“…It would be developed to be the corona discharge with the lower supplied voltage than that of the other electrode shapes. [ 12 ] The sharp tip electrode is popular to be used with the plasma jet model and the corona discharge. These types of models have uncomplicated designs, which can be easily used and are popular in the applications.…”

Effect of cold plasma and elicitors on bioactive contents, antioxidant activity and cytotoxicity of Thai rat‐tailed radish microgreens

“…Cold plasma is an emerging technology primarily used for microbial disinfection, surface modification and, more recently, for enhancement of seed germination 1 . Cold plasma or non‐thermal plasma is an ionized gas derived from gas ionization under corona discharge, microwaves, dielectric barrier discharge or radiofrequency waves 2,3 . Cold plasma has been used to improve the germination rate of seeds and growth rate of soybean sprouts, tomatoes, radish and sun flower 4–9 .…”

“…1 Cold plasma or non-thermal plasma is an ionized gas derived from gas ionization under corona discharge, microwaves, dielectric barrier discharge or radiofrequency waves. 2,3 Cold plasma has been used to improve the germination rate of seeds and growth rate of soybean sprouts, tomatoes, radish and sun flower. [4][5][6][7][8][9] Cold plasma was also shown to induce growth regulating factor, antioxidant enzymes and energy metabolism-related genes in soybean sprouts.…”
