“…Activated liquid is used in the biomedical and biological research and food preservation. A positive influence of PAW enriched with RONS (mainly H 2 O 2 and NO 2 -) on plant growth is well documented [25,[31][32][33]. The H 2 O 2 concentration, electrical conductivity, redox potential, and pH of water treated with piezoelectric direct discharge CAP are of great interest (Figure 10).…”

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.

This study investigates the interaction between two counterpropagating atmospheric pressure plasma jets when their respective streamer ignition times are varied by introducing a phase difference between the AC waveforms used to generate them. When the plasma jets are driven in phase, the streamers form at approximately the same time, resulting in a dark region between the two jets. As the phase difference increases, this dark region shifts toward one of the electrodes. With a sufficiently large phase difference, this region vanishes, giving rise to a uniform plasma channel spanning the distance between the electrodes. High-speed imaging reveals that the interaction between the streamers within the channel reduces the streamer propagation length at intermediate phase differences. At large phase differences, the propagation distance of each streamer is enhanced due to the absence of the opposing streamer. Increasing the phase from 0° to 160° reduced the power consumption of the two jets by about 10%, while there was no significant change in the electron density or the N2 vibrational/rotational temperature. Finally, we show how phase-shifting enhances the interaction with three-dimensional objects located between the opposing jets, enabling the treatment of 3D substrates.
