Electron and gas temperature-driven chemistry during microdischarges formed in water vapour bubbles
Florens Grimm, Jan-Luca Gembus, Jana Schöne +3
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…
Concentration profiles of OH and HO in plasma-treated water: influence of power, gas mixture and treatment distance
Anna Lena Schöne, Steffen Schüttler, Talisha Mroà +4
Plasma liquid interactions are important for a range of applications. For these, HO and OH represent two key reactive species, whose concentrations in liquids need to be co…
Atomic oxygen densities in He/O micro-scaled atmospheric pressure plasma jets: a systematic model validation study
Youfan He, Ralf Peter Brinkmann, Efe Kemaneci +1
Reactive species produced by atmospheric pressure plasma jets have high application potential in the fields of biomedicine and surface processing. An extensive validation between t…
Dynamics of reactive oxygen species produced by the COST microplasma jet
Sascha Chur, Robin Minke, Youfan He +9
This study is focused on measuring the densities of the excited molecular oxygen species, O and O, produced in…
Characterisation of single microdischarges during plasma electrolytic oxidation of aluminium and titanium
Jan-Luca Gembus, Vera Bracht, Florens Grimm +4
Plasma electrolytic oxidation (PEO) is a technique used to create oxide-ceramic coatings on lightweight metals, such as aluminium, magnesium, and titanium. PEO is known for produci…
Influence of gas flow rate on modes of reactive oxygen and nitrogen species in a grid-type surface dielectric barrier discharge
Angie Natalia Torres Segura, Kazumasa Ikuse, Satoshi Hamaguchi +2
The presented work investigates a surface dielectric barrier discharge (SDBD) operated dry synthetic air as the working gas using a combination of experimental measurements and sim…
