The lifetime of tungsten cathodes used in plasma spray torches is limited by processes leading to a loss of cathode material. It was reported in the literature that the mechanism of their erosion is the evaporation. A model of the ionization...
A time-dependent, spatially one-dimensional fluid-Poisson model has been applied to analyse the impact of small amounts of tetramethylsilane (TMS) on the discharge characteristics of an atmospheric-pressure dielectric barrier discharge (DBD) in...
The gas pressure is an effective parameter to control plasma-chemical reactions, but its adjustment often requires substantial effort. In the Venturi-DBD (VDBD), the pressure can be set to any value between 100 mbar and 1000 mbar reliably and...
The Biofilm Jet is a plasma jet used for the removal of bacterial biofilms. The system is still in an experimental stage of development, but its efficacy has already been investigated and compared to other devices.
The hairline plasma jet (hairlINePlasma) is a cold atmospheric pressure plasma source mainly for biological and medical applications. hairlINePlasma uses the physical effect of negative dc corona discharges and produces a nanosecond self-pulsed...
Plasma as a cross-sectional technology in many industry branches, but also in research laboratories, is an indispensable tool in surface treatment. Plasma technology is used everywhere where quality, productivity, environmental...
The HelixJet is a capacitively coupled radio-frequency (RF) plasma source operating at atmospheric pressure. The RF power is applied to two double helix electrodes. The electrodes are placed outside a quartz tube fed by the working gas. The...
The Ion Wind DBD uses a flat plasma electrode to create a surface dielectric barrier discharge (DBD) in the room air flowing over it. An additional “extraction” electrode is arranged in parallel to form a rectangular ventilation duct. The...
Presented data was obtained from the analysis of the impact of the electrode proximity on the streamer breakdown and development of pulsed-driven dielectric barrier discharges (DBDs) in a singlefilament arrangement in a gas mixture of 0.1 vol% O2...
The invention relates to a method for the biological decontamination of material to be treated (4) by means of a reactive gas (R) comprising the generation of a reactive gas (R) from a process gas by igniting a plasma, filling a container (3)...
