TL;DR: In this paper, an experimental observation of fast-moving plasma bullets produced in an atmospheric dielectric-barrier discharge jet is reported, which is likely related to the ionization wave, and time and space resolved optical emission spectroscopy show that reactive plasma species can be delivered to different spatial sites with varying quantities.

TL;DR: In this article, the authors used a handheld, mobile plasma jet powered by a 12 V dc battery and operated in open air without any external gas supply for effective biofilm inactivation using room-temperature air plasmas.

TL;DR: In this paper, a numerical and experimental study of plasma jet propagation in a low-temperature, atmospheric-pressure, helium jet in ambient air is presented, where a self-consistent, multi-species, two-dimensional axially symmetric plasma model with detailed finite-rate chemistry of helium-air mixture composition is used to provide insights into the propagation of the plasma jet.

TL;DR: In this article, the main electron heating mechanism is Ohmic heating, which has distinct spatial and temporal evolutions in the α and γ modes, and ionizing avalanches in the sheaths are initiated not only by secondary electrons but also by metastable pooling reactions.

TL;DR: In this paper, a computational study is presented to demonstrate that dielectric barriers provide an effective control over unlimited current growth and allow rf APGDs to operate at very high current densities with little danger of the glow-to-arc transition.
