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...
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...
This study is focused on measuring the densities of the excited molecular oxygen species, O2(a1∆g) and O2(b1Σ+g), produced in a COST atmospheric pressure plasma jet using a helium-oxygen mixture. Knowledge of the ozone density is critical for...
The ion energy distribution functions (IEDF) have been measured for a helium atmospheric pressure dielectric barrier discharge jet expanding into the air and impacting a metal or ceramic surface. The plasma jet produces ionization waves as guided...
High-frequency technological low-temperature plasmas play a key role in various industrial processes of high societal relevance such as semiconductor manufacturing and gas conversion. Due to their complexity, the fundamentals of their operation...
Atmospheric plasma jets enable the precise generation and transport of reactive oxygen and nitrogen species (RONS) to a designated target, making them particularly valuable for applications in plasma medicine. In these contexts, it is crucial to...
Processes at the plasma boundaries, including the electrodes, can significantly influence plasma properties, among them the plasma density, the flux-energy distribution of various particle species, etc. The emission of secondary electrons, in...
Dielectric barrier discharges (DBDs) offer great potential for applications such as volatile organic compounds (VOCs) conversion or plasma catalysis. For many of these applications, an admixture of molecular oxygen is important, for example, to...
