SAPP XX and COST TD1208 meeting in Slovakia – January 2015






20th Symposium on Application of Plasma Processes and COST TD1208 Workshop on Application of Gaseous Plasma with Liquids will be held in Tatranská Lomnica (Slovakia) from 17 to 22 Janaury 2015.

Our contribution:

– Dr. Matteo Gherardi oral presentation – Characterization of a non-equilibrium atmospheric pressure plasma jet driven by nanosecond voltage pulses

Report on the characterization of a cold atmospheric pressure plasma jet driven by high-voltage nanosecond pulses. As diagnostic techniques, iCCD imaging was employed to investigate the discharge structure, Schlieren imaging for the study of the jet fluid-dynamic behaviour and Optical Emission Spectroscopy (OES) to qualitatively evaluate the chemical composition of the discharge. Moreover, plasma plume temperature was measured by means of fiber optic temperature sensors and total UV irradiance through a UV power meter. Results attest the suitability of the plasma source for biomedical applications.

– Eng. Emanuele Simoncelli poster presentation “Plasma Gun decontamination of bacteria in liquid suspension”

Work on the investigation of the antibacterial activity and chemical composition of a flexible Plasma Gun, able of propagating plasma through dielectric capillaries over distances of tens of centimeters. Results on treatment of liquid suspensions contaminated with Staphylococcus aureus and quantitative evaluation the associated reduction of bacterial load in different operating conditions are presented.
