Glycerol can be effectively converted to synthesis gas (selectivity higher than 80%) with small amounts of water or no water using plasmas at low temperature and atmospheric pressure, without external heating.

Cold atmospheric pressure plasma jets (APPJs) are able to generate chemically reactive species desired for material processing and biomedical applications. A great amount of attention has been devoted to characterizing these APPJ sources and expanding their applications. Less is known on the interaction mechanisms between cold atmospheric pressure plasma and material surfaces. Since both plasma...

Biomedical applications of plasma require its efficacy for specific purposes and equally importantly its safety. Herein the safety aspects of cold plasma created with simple atmospheric pressure plasma jet produced with helium gas and electrode discharge are evaluated in skin damage on mouse, at different duration of exposure and gas flow rates. The extent of skin damage and treatments are syst...

Abstract Low-temperature plasma jets at atmospheric pressure generated by sinusoidal and positive pulsed voltages interact differently with the treated surface. In experiment in numerical simulations, we compare operating modes of helium for these types voltages. The discharge current on surface over time heating are studied different parameters acceptable anticancer therapy. intensity emission...

Conventional plasma jets for biomedical applications tend to have several drawbacks, such as high voltages, gas delivery, large probe volume, and the formation of discharge within organ. Therefore, it is challenging employ these inside a living organism’s body. Thus, we developed single-electrode tiny jet evaluated its use clinical applications. We investigated effect voltage input flow rate on...

BACKGROUND Cold atmospheric pressure plasma (CAP) with its many bioactive properties has defined a new medical field: the plasma medicine. However, in the related form of high-frequency therapy, CAP was even used briefly a century ago. The aim of this study was to review historic CAP treatments and to obtain data regarding the antimicrobial efficacy of a historical high-frequency plasma device....
