There are three major multi-electron reactions in nature: nitrogen fixation by bacteria, water oxidation photosynthesis, and oxygen reduction during respiration. Here we found that a cold atmospheric pressure He-plasma jet (CAPPJ) can oxidize N2 to HNO3 HNO2 at low temperature the plasma-air/water interface. Redox induced plasma occur not only plasma/air plasma/water interfaces, but also volume...

This paper presents results that show the effect of hydrothermal carbonization and subsequent cold plasma jet treatment with helium argon on structure sorption properties a material—spent brewery grain. Treatment activated carbon, atmospheric jet, was used comparatively. The activation pore materials carried out by volumetric method at low pressure (N2, 77 K). specific surface area as well tota...

Flowing low temperature atmospheric pressure plasma devices have been used in many technological applications ranging from energy efficient combustion through to wound healing and cancer therapy. The generation of the plasma causes a sudden onset of turbulence in the inhomogeneous axisymmetric jet flow downstream of the plasma plume. The mean turbulent velocity fields are shown to be self-simil...

In this study, the drying kinetics of saffron stigmas pretreated by atmospheric pressure cold plasma pretreatment (15, 30, 45 and 60 s) followed by hot air drying (60°C and 1.5 m/s) were modeled using 10 conventional mathematical thin layer models. The use of cold plasma pretreatment reduced drying time and enhanced effective moisture diffusivity (Deff). The most accurate models describing beha...
