Inactivation of Schistosoma Using Low-Temperature Plasma

open access: yesMicroorganisms, 2020
The inactivation of Schistosoma mansoni cercariae and miracidia was achieved by exposure to plasma produced by the positive, negative, and axial negative corona discharges.

Corona discharge processes [PDF]

open access: yesIEEE Transactions on Plasma Science, 1991
Applications of corona discharge induced plasmas and unipolar ions are reviewed. Corona process applications emphasize one of two aspects of the discharge: the ions produced or the energetic electrons producing the plasma. The ion identities depend on the polarity of the discharge and the characteristics of the gas mixture, specifically on the electron

Deposition of SiOx Thin Films by Corona Discharges at Atmospheric Pressure

open access: yes, 2022
The corona discharge (also called dielectric barrier discharge) is a non-thermal transient gas discharge which can be operated at atmospheric pressure. A novel application of corona discharges is the deposition of thin films.

Emission Spectrum Analysis of Two Typical Partial Discharge Forms Under High Frequency Square Wave Voltages

open access: yesIEEE Access, 2020
Although the increase in frequency improves the transmission efficiency of high-frequency transformer, a higher probability of insulation failure is caused by high-frequency partial discharges.

Frequency Resolved Partial Discharges Based on Spectral Pulse Counting

open access: yesEnergies, 2021
A partial discharge (PD) classification methodology based counting PD pulses in the spectral domain is proposed and presented in this paper. The spectral counting data are processed using the proposed PD Spectral Pulse Counting Mapping technique (PD-SPCM)

Fog dispersion by using electrostatic experimental techniques

open access: yesEnergy Reports, 2020
In this work, the fog dispersion was evaluated through three different electrostatic experiments, as well as the environment impact in the Epipremnum aureum plants after being exposed to the electric field and to the ozone concentrations generated during
