“…Plasma consist of the energetic electrons, neutral atoms, excited species, positive ions and negative ions, metastable atoms and free radicals. In its configuration, comsol physics provides modelling and analysis power [10][11][12] for different areas [10][11][12][13]. In addition, software package COMSOL also contains optional modules inside it.…”

The plasma parameters have been determined in an infrared image converter for the InP based plasma cell in a broad range of gas pressure from 10 Torr to 760 Torr at room temperature. The electrical properties of the system are controlled by both the plasma and InP electrode. InP has high electron mobility compared to other semiconductors and it can be used for high-speed optoelectronic device applications. Further, any small change in the charge transport mechanism may cause important changes in the system characteristics. The experimental measurements are carried out in air and He media. The homogeneity of the discharge radiation emission depends on the resistivity distribution of the photodetector plate and the radiation intensity is proportional to the plasma current. Local changes in the resistivity of the semiconductor result in local changes in the current and plasma emission.

In this paper, a dielectric barrier discharge plasma based atmospheric pressure plasma jet has been generated in a floating helix and floating end ring electrode configuration using mixture of argon and nitrogen gases (50:50 ratio). This configuration is subjected to a range of supply frequencies (10–25 kHz) and supply voltages (6.5–9.5 kV) at a fixed rate of gas flow rate (i.e., 1 l/min). The electrical characterization of the plasma jet has been carried out using a high voltage probe and current transformer. The current–voltage characteristics have been analyzed, and the power consumed by the device has been estimated at different applied combinations of supply frequency and voltages for optimum power consumption and maximum jet length. A comparative analysis of the results of the above experiments has shown that maximum power consumed by the device in helix electrode configuration with end ring is 19 W for (Ar+N2) mixture as compared to only 12 mW and 7.7 mW for Ar and He gas respectively (With end ring), this may be due to the main ionization mechanisms which are different depending on the working gas. Furthermore, maximum jet length of 42 mm has been obtained for He gas at 6 kV/25 kHz due to penning ionization process in comparison to jet lengths of only 32 mm for Ar gas and jet length of only 26 mm for Ar+N2 mixture. The obtained average power consumed and maximum jet length for mixture of (Ar+N2) gases are 6.5 W and 26 mm.

“…Several methods have been developed for generating the nonequilibrium atmospheric plasma at atmospheric pressure. Cold atmospheric plasma (CAP) could be generated using a gas flow (or the gas mixture flow) to produce the outlet plasma flux [13,14]. This application of CAP is well documented in publications.…”

Properties and Use of Water Activated by Plasma of Piezoelectric Direct Discharge

The distilled water was exposed to a cold atmospheric plasma (CAP) generated by the piezotransformer. The treatment was carried out on a six-well plate. Exposure time was from 30 s to 10 min. The emission spectra were obtained. Physical and chemical changes of activated water were observed for 8 days. The reactive oxygen and nitrogen species (RONS) were investigated. RONS production dependence on the exposure time and RONS lifetime in the treated liquid was determined using absorbance spectra. Quantitative assessment was made of the nitrite and nitrate concentration change over time after treatment. The medium conductivity and redox potential varied linearly depending on exposure time. The pH value change correlates with nitrate anion concentration. The concentration of peroxide hydrogen increased depending on CAP water treatment duration. The RONS concentration after liquid media processing with piezoelectric direct discharge CAP is a novel result. Biogeosystem Technique provides CAP activated water agriculture synergetic effect.
