Cold atmospheric pressure plasma (CAPP) treatment is a highly effective method of protecting seeds, plants, flowers, and trees from diseases infection significantly increasing crop yields. Here we found that cold He-plasma jet (CAPPJ) can also cause side effects damage to plants if the exposure time too long. Reactive oxygen nitrogen species (RONS), electromagnetic fields, ultraviolet photons e...

Atmospheric pressure plasma jets are well-known in the plasma chemistry community because of their novel applications. However, in spite of a large amount of publications, the physical chemistry of plasma jet/surface interactions is still unknown. In this work, an atmospheric pressure plasma jet (APPJ) in pure argon will be used to modify the surface of PET non-woven textiles. In a first part o...

The ambient air is entrained intensively into atmospheric pressure thermal plasma jets. A system for shielding plasma jet has been used to improve jet characteristics and reduce oxygen content. Different gases have been applied as a shroud gas – argon, acetylene, methane, mixtures of acetylene-nitrogen and hydrogen-nitrogen. All shroud gases used in experiments affected plasma jet making the pr...

Cold atmospheric-pressure plasma jet not only modifies surface morphology but also introduces functional groups on sample surfaces. In this work, TiO2 nanorods/carbon fiber (TNCF) is hydrothermally prepared, and hydrogen-doped TNCF (H:TNCF) obtained by the treatment of using cold Ar/H2 Plasma jet. H OH spectral lines are observed from emitting spectrum Nanoscaled protrusions appear at top nanor...

This work focused on qualitative and quantitative detection of oxygen free radicals in liquids after plasma treatment with an atmospheric pressure argon plasma jet by electron paramagnetic resonance spectroscopy (EPR). For the treatment, a shielded plasma jet, where the active effluent zone is surrounded by a protective gas curtain was used.
