Abstract Erosion of an aluminium oxide surface as well a formation coating on substrate, comparable with erosion and induced by plasma electrolytic oxidation (PEO), can be caused at atmospheric pressure conditions DBD-like (Dielectric Barrier Discharge) jet. Obtained experimental results conform previously assumed similarity the mechanisms jet PEO microdischarges. The mechanism predominantly in...

In this study, we propose a rapid plasma-assisted nitriding process using H2/N2 mixture gas in an atmospheric pressure plasma jet (APPJ) system to treat the surface of SKD11 cold-working steel order increase its hardness. The generated NH radicals region are used implement ion-bombardment for tempered martensite structure within 18 min form functional nitride layer with increased microhardness ...

Gas phase non-equilibrium plasmas containing water vapor are of growing interest for many environmental and biomedical applications. Nonetheless the plasma kinetics that is of the utmost importance for these applications remain poorly understood [1]. A He-H2O reaction mechanism has been compiled and validated for a diffuse atmospheric pressure glow discharge [2]. Models of the more complicated ...

Plasma co-polymers (co-p) were deposited with an atmospheric pressure plasma jet (APPJ) using a precursor mixture containing hexamethyldisiloxane (HMDSO) and limonene. A coating fragments from both precursors siloxane, carbonyl nitrogen functional groups was deposited. The flow rate of limonene found to be important parameter for co-polymerization tune the formation structure groups. FTIR XPS a...

Abstract Cold physical plasma is a partially ionized gas that generates various components identified as potential anticancer compounds. Due to its topical application, cold plasmas are suitable, especially in dermatological applications. We, therefore, tested the effects skin cancer cells vitro . An atmospheric pressure argon jet was used source. The exposure alone reduced metabolic activity a...

Aflatoxins, produced by Aspergillus flavus and A. parasiticus, can contaminate different foodstuffs, such as nuts. Cold atmospheric pressure plasma has the potential to be used for mycotoxin detoxification. In this study, the operating parameters of cold atmospheric pressure plasma were optimized to reduce the presence of aflatoxins on dehulled hazelnuts. First, the effect of different gases wa...

BACKGROUND Current therapies for bone cancers - either primary or metastatic - are difficult to implement and unfortunately not completely effective. An alternative therapy could be found in cold plasmas generated at atmospheric pressure which have already demonstrated selective anti-tumor action in a number of carcinomas and in more relatively rare brain tumors. However, its effects on bone ca...
