This paper reports the use of dielectric barrier discharge (15.65 kV, 50 Hz) produced in an air and argon environment at atmospheric pressure to modify the surface of Nylon 6. Power dissipation in air and argon DBD was determined to be 14.60 W and 12.00 W, respectively. Similarly, the average density and temperature of an electron in air DBD were found to be 1.74 ×1011 cm-3 and 1.31 eV, respectively, while the values were 2.50 ×1011 cm-3 and 0.68 eV in argon DBD. The water contact angle (WCA) was measured to confirm the enhancement in wettability. On treating the sample with air DBD for 15 minutes, the contact angle reduced from 134.07° ± 3.20° to 89.11° ± 3.06° while it was reduced to 82.74° ± 4.20° within 1 minute using argon. The study found that treating a hydrophobic sample of Nylon 6 with DBD for a certain period of time transformed it into a hydrophilic one, and extending the treatment time further enhanced its wettability. The use of argon DBD was found to be more effective than air DBD in altering the surface properties of the sample, as the sample became hydrophilic after only one minute of treatment with argon DBD and completely wettable after three minutes. The findings suggest that air and argon DBD have potential applications in modifying the surface properties of Nylon 6, which could have practical implications in the production of textiles, membranes, and other materials.

“…However, the data are still limited, and further research is needed to comprehensively understand the mechanisms underlying the impact of plasma on crops. Numerous research studies have been conducted in the field of plasma agriculture, with a primary focus on investigating the effects of plasma treatment on seed germination in various common − and exotic crops. − A model plant, Arabidopsis thaliana, has also become a subject of interest in recent plasma agriculture research. Recent studies have indicated that atmospheric plasma treatment can have a positive impact on alleviating seed dormancy in A.…”

This study investigates the impact of plasma−seed interaction on germination and early plant development, focusing on Arabidopsis thaliana and Brassica napus. The investigation delves into changes in chemical composition, water absorption, and surface morphology induced by plasma filaments generated in synthetic air. These analyses were conducted using scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). Although plasma treatment enhanced water absorption and modified surface chemistry, its impact on germination demonstrated species-and context-dependent variations. Notably, the accelerated germination and morphogenesis of seedlings in microbiome-enriched (MB+) soil could be achieved also in microbiomedeprived (MB−) soil by short-term plasma treatment of seeds. Remarkably, the positive effects of plasma treatment on early developmental events (germination, morphogenesis) and later events (formation of inflorescences) were more pronounced in the context of MB− soil but were accompanied by a slight decrease in disease resistance, which was not detected in MB+ soil. The results underscore the intricate dynamics of plasma−plant interactions and stress the significance of accounting for the soil microbiome while designing experiments with potential field application.

“…It is a waterless, chemical-free, eco-friendly method with minimum food contact and higher rates of toxin destruction [10][11]. The technology of seed treatment with plasma before planting may minimize pesticide consumption during the crop cycle and increase crop yield [12].Boliu, et al,investigated the effect of plasma on the germination of eight types of seeds directly (exposingwater to plasma) and indirectly (exposing water to plasma and then placing the seeds in plasma-applied water). Their results indicated that direct plasma application is more effective on seed germination than the indirect method because of the greater impact of short-lived species produced in the direct process [1].…”

“…The etching effect of plasma on the seed tissue leads to this improvement through the water absorption capacity accession and activation of the effective physiological response [13].Cold plasma treatment increased the germination of canola seeds under drought stress [14]. The germination characteristics of radish seeds were improved by the effect of plasma for the appropriate treatment time, while the long treatment led to a decrease in the germination percentage [12]. Maxim Bafoil et al investigated the effects of lowtemperature plasma treatment on A.thaliana seed germination under salt stress and they found out that plasma application increases the germination rate of treated seeds in saline stress, which makes it possible to invest more areas with saline soil [15].…”

In this research,a corona plasma discharge device is designed and used on the plant medium in ambient air. Furthermore, the kinetic theory of plasma is utilized and its energy and drift velocity impact on the plant atmosphere analytically is investigated in the modeling section. The effect of cyclotronic frequency, and plasma particle drift velocity on particle energy and its distribution during the collision with the plant surface as an essential factor for the germination process is analyzed. This transfer of energy appears as the kinetic energy of the particles and can be explained in the form of the required energyto prepare an appropriate growth atmosphere for the seeds. The higher plasma particle drift velocity leads to higher energy distribution on the seed surface. The effect of low-temperature pulsed plasma application period and direction on the germination and growth rate of seeds are investigated. Dry chickpea seeds are taken into consideration to be the outturn of the same farm and stored in the same barn and condition. The seeds are exposed to plasma at time intervals of 3,7, and 12 minutes. The results showthat the seeds with 7 minutes of plasma treatment had better growth and rejuvenation compared to the control sample and other samples. The 3-minute plasma application to samples decreased the germination and growth. Additionallyseeds are treated by plasma beam from the germination site (embryo),the back of the embryo, and the cotyledons. The results indicate that applying plasma to the embryo enhances the growth of the chickpea seeds after 30 days of observation.
