The research will focus on the fundamentals of non-equilibrium plasmas and their interaction with the surrounding media such as solids or liquids using spectroscopic techniques.
A humid atmospheric pressure plasma jet was used to treat an aqueous liquid. The transport of hydrogen peroxide and hydroxyl from the plasma to the liquid was analyzed. Two in-situ liquid diagnostics for each species were compared and validated....
A new actinometry approach, state enhanced actinometry (SEA), is presented. This diagnostic uses the emission of the atomic states O(3p3P (λ=844.6 nm), Ar(2p1) (λ=750.4 nm) and He(33S) (λ=706.5 nm) and allows the atomic oxygen density and the...
Micro cavity plasma arrays have numerous applications, such as the treatment of volatile organic compounds (VOCs) or the generation of new species. In recent years, the focus has also shifted to plasma catalysis, in which catalytic surfaces are...
Two-dimensional spatially resolved absolute atomic oxygen densities are measured within an atmospheric pressure micro plasma jet and in its effluent. The plasma is operated in helium with an admixture of 0.5% of oxygen at 13.56 MHz and with a...
Here we present a method for the operando determination of absolute absorbed power in an RF atmospheric pressure helium plasma discharge using miniaturized probes. A detailed error analysis demonstrates the reliability of the measured power...
