The transportation of plasma-generated species through a liquid environment is a key step within the plasma-driven biocatalysis process, but is also of great importance for other systems with plasma-liquid interfaces. The aim of this study is to...
Non-thermal atmospheric pressure plasmas have an antiseptic activity beneficial in different medical applications. In a genome-wide screening, hydrogen peroxide and superoxide were identified as key species contributing to the antibacterial...
Plasma-driven biocatalysis utilizes in situ H2O2 production by atmospheric pressure plasmas to drive H2O2-dependent enzymatic reactions. Having previously established plasma-driven biocatalysis using recombinant unspecific peroxygenase from...
Plasma-generated H2O2 can be used to fuel biocatalytic reactions that require H2O2 as co-substrate such as the conversion of ethylbenzene to (R)-1-phenylethanol ((R)-1-PhOl) catalyzed by unspecific peroxygenase from Agrocybe aegerita (rAaeUPO)....
Atmospheric pressure plasmas are widely used for nitrogen fixation processes to produce ammonia NH3 or nitrogen oxides NOx , including for example nitrite NO2– or nitrate NO3–. Small scale atmospheric pressure plasma jets (APPJs) can provide the...
Erosion of an aluminium oxide surface as well as a formation of an aluminium oxide coating on an aluminium substrate, comparable with erosion and oxide formation induced by plasma electrolytic oxidation (PEO), can be caused at atmospheric...
Cold atmospheric pressure plasmas are used for surface decontamination or disinfection, e.g. in clinical settings. Protein aggregation has been shown to significantly contribute to the antibacterial mechanisms of plasma. To investigate the...
Non-thermal plasmas are used in various applications to inactivate biological agents or biomolecules. A complex cocktail of reactive species, (vacuum) UV radiation and in some cases exposure to an electric field together cause the detrimental...
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...
The unipolar pulsed-plasma electrolytic oxidation (PEO) of aluminum has been replaced by bipolar pulsed methods that use a so-called 'soft-sparking' mode.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...
