Microdischarges formed in bubbles immersed in liquids are of interest for materials synthesis and chemical conversion applications in the frame of plasma-driven electrochemistry. A key challenge associated with controlling such processes is the...
Precise control of ion energy distribution functions (IEDF) is crucial for selectivity as well as control over sputter rate and substrate damage in nanoscale plasma processes. In this work, a low frequency (100 kHz) tailored pulse-wave-shaped bias...
Numerous studies have shown that dielectric barrier discharge (DBD) and DBD-like plasma jets interact with a treated surface in a complex manner. Eroded traces after treatment cannot be explained by conventional plasma-surface interaction theory....
A key to the understanding of mechanisms during plasma electrolytic oxidation (PEO) is the interaction between microdischarges and an amorphous oxide film. The PEO microdischarges, which are randomly distributed on the surface of a treated...
Paper Secondary electron emission from magnetron targets, published in IOP PSST 2023. DOI 10.1088/1361-6595/acd57e
Ion-induced secondary electron emission at a target surface is an essential mechanism for laboratory plasmas, i.e. magnetron sputtering discharges. Electron emission, however, is strongly affected by the target condition itself such as oxidation...
Plasma-driven in situ H2O2 generation offers a potential sustainable route for oxidative biotransformations, but its application has been hindered by challenges such as insufficient H2O2 production and enzyme degradation from direct plasma...
The elementary processes during the fixation of nitrogen by plasma catalysis are studied in a low-pressure plasma experiment with N$_2$ and O$_2$ as source gases. The formation of surface groups on an iron oxide foil is monitored with infrared...
Data of figures for the paper titled "Synergistic control of radical generation in a radio-frequency atmospheric-pressure plasma jet via voltage waveform tailoring and structured electrodes"
Pulse modulation of an RF-driven atmospheric pressure plasma jets (APPJs) can be used to control the production of short-lived and long-lived species. This was applied for the production of H2O2 by a humidified He APPJ operating at 13.56 MHz. In...
