Increase of Productivity and Neutralization of Pathological Processes in Plants of Grain and Fruit Crops with the Help of Aqueous Solutions Activated by Plasma of High-Frequency Glow Discharge [PDF]

open access: yesPlants, 2021
In this work, we, for the first time, manufactured a plasma-chemical reactor operating at a frequency of 0.11 MHz. The reactor allows for the activation of large volumes of liquids in a short time.

Volatile Organic Compound Fragmentation in the Afterglow of Pulsed Glow Discharge in Ambient Air [PDF]

open access: yesMolecules, 2022
Glow discharge (GD) source gained an increased level of attention in relation to the analysis of volatile organic compounds (VOCs) since past work showed that this soft ionization method allowed direct analysis of VOCs with minimal fragmentation, however,

Alignments of a Microparticle Pair in a Glow Discharge [PDF]

open access: yesMolecules, 2021
Stability of a vertically aligned microparticle pair in a stratified glow DC discharge is experimentally investigated. Using laser perturbations, it is shown that, for the same discharge parameters, a pair of microparticles can be suspended in two stable

Detection of trace heavy metals using atmospheric pressure glow discharge by optical emission spectra

open access: yesHigh Voltage, 2019
In this Letter, atmospheric pressure glow discharge based on a small discharge gap is excited by sine AC voltage in air on purpose of detecting trace heavy metal elements in solid samples, which makes the detection limits of trace heavy metal elements ...

Generation of a planar direct-current glow discharge in atmospheric pressure air using rod array electrode [PDF]

open access: yesScientific Reports, 2017
Scaling up atmospheric pressure glow discharge to large volume is desirable for low-temperature plasma applications. In this paper, an approach to generate a glow discharge in a planar shape with a fairly large volume is proposed in atmospheric pressure ...

Generation and Diagnostics of Ambient Air Glow Discharge in Centimeter-Order Gaps

open access: yesIEEE Access, 2020
Re-pulsing glow discharges in gaps up to 2 cm were experimentally investigated in atmospheric pressure air. Discharge was ignited as a sequence of spark and glow discharge and sustained in a glow regime after ignition. It was confirmed that the discharge
