Dielectric barrier discharges are an emerging technology for the plasma-catalytic removal of volatile organic compounds and other gas purification challenges such as the removal of O2 traces from H2. Packed-bed reactors are mainly used for these appl

The unipolar pulsed-plasma electrolytic oxidation (PEO) of aluminum has been replaced by bipolar pulsed methods that use a so-called ‘soft-sparking’mode. This method results in an effective reduction of intense microdischarges, which are detrimen

Microdischarges occurring during plasma electrolytic oxidation are the main mechanism promoting oxide growth compared to classical anodization. When the dissipated energy by microdischarges during the coating process gets too large, high-intensity di

In this work a gliding arc plasmatron consisting of a filamentary discharge rotating in a nitrogen vortex flow at low DC current (I = 100 mA) is investigated. The gas flow swirl of the plasmatron is produced by six tangential gas inlets. The Reynolds

Micro-electromechanical systems (MEMS) have a broad area of application in modern technology. Nanostructured sensors allow the shrinkage of measuring systems to micrometer size (lab-on-a-chip). The authors present a micro-fabricated mass spectrometer
