TLDR
Using surface type air atmospheric pressure plasma, Wang et al. as mentioned in this paper investigated the amount of ozone and other reactive species generation with variations of the surface temperature of an electrode through an optical emission spectrum and a tube type gas detector.Abstract:
Using surface type air atmospheric pressure plasma, we investigated the amount of ozone and other reactive species generation with variations of the surface temperature of an electrode through an optical emission spectrum and a tube type gas detector. Reduced version of global model (GM) was employed to complement these experimental observations. The results of the model matched well with the experimental data. The amount of ozone generated from the surface type air plasma device was dramatically reduced with increasing temperature. Atomic oxygen (O) and nitric oxide (NO) radicals, which are important agents for biomedical applications, proportionally increased with increasing temperature. We also elucidated the dominant reaction related to the generation or loss of these radicals based on temperature variation through our GM.read more

Air Plasma Kinetics Under the Influence of Sprites
TL;DR: In this article, a full time-dependent kinetic study is presented for the main microscopic collisional and radiative processes underlying the optical flashes associated with an impulsive (τ = 5 µs) discharge in the form of a single sprite streamer passing through an air region of the mesosphere at three different altitudes (63, 68 and 78 km).

Differences in cellular damage induced by dielectric barrier discharge plasma between Salmonella Typhimurium and Staphylococcus aureus.
TL;DR: Dielectric barrier discharge (DBD) plasma treatments are more effective against Gram negative bacteria than Gram-positive bacteria; however, ROS produced from plasma first penetrated the cell wall and membrane of Gram- positive bacteria before reacting with internal cellular components and killing the bacteria.
