(1) Background: The purpose of this study was to investigate the effects low-dose non-thermal atmospheric plasma (NTP) on proliferation and migration human immortalized keratinocytes (HaCaT cells) its molecular mechanisms. (2) Methods: NTP HaCaT cells were detected by cell viability, wound healing assay, cycle, mitochondrial membrane potential detection, western blot, role reactive oxygen speci...

Ceramic oxygen permeable membranes (OPMs) are widely considered the “next generation” technology for pure separation and catalytic membrane reactors. However, main issue of OPM is high operating temperature (above 800 °C) resulting implications materials, cost, as well complexities (e.g., sealing, creep deformation, thermal shock during cycling). A new design coupling La0.6Sr0.4Co0.2Fe0.8O3-? w...

Novel, effective methods to control and prevent spoilage and contamination by pathogenic microorganisms in meat and meat products are in constant demand. Non-thermal pasteurization is an ideal method for the preservation of meat and meat products because it does not use heat during the pasteurization process. Atmospheric pressure cold plasma (APCP) is a new technology for the non-thermal pasteu...

In continuation of our previous reports on the broad-spectrum antimicrobial activity of atmospheric non-thermal dielectric barrier discharge (DBD) plasma treated N-Acetylcysteine (NAC) solution against planktonic and biofilm forms of different multidrug resistant microorganisms, we present here the chemical changes that mediate inactivation of Escherichia coli. In this study, the mechanism and ...

A laser-assisted plasma-coating technique at atmospheric pressure (LAPCAP) has been investigated. The electron temperature, electron density and gas temperature of the atmospheric-pressure plasma have been measured using optical emission spectroscopy (OES). LAPCAP utilizes laser ablation of 3 mol% yttria-stabilized zirconia into an atmospheric helium/nitrogen plasma to deposit thermal barrier c...

In this paper, formulae are given for computing the non-thermal emission of superthermal hydrogen atoms generated through charge exchange by the bombardment of the solar atmosphere by an oblique incident proton beam with a given pitch angle. Specifically, we discuss the non-thermal emission of hydrogen in Lyα , Lyβ, and Hα lines and find that the profiles of these lines are quite different from...

The self-organized discharge behaviour occurring in a non-thermal radio-frequency plasma jet in rare gases at atmospheric pressure was investigated. The frequency of the azimuthal rotation of filaments in the active plasma volume and their inclination were measured along with the gas temperature under varying discharge conditions. The gas flow and heating were described theoretically by a three...
