This paper reports on the selection of insulating material types in a developed atmosphericpressure non-thermal plasma jet (ANPJ-II) device which was operated previously in our laboratory based on the minimum erosion area of the insulator’s nozzle. Three identical insulator groups used in our experiment include; Teflon insulator material with different thicknesses of 1.5 mm and 2 mm respectivel...

Treatment of NOx in diesel engine exhaust represents a big opportunity for the environmental application of low-temperature plasmas. In this paper NOx conversion to N2 was investigated by Plasma/Catalyst System Catalytic activity was enhanced by the assistance of plasma ,and the plasma/Catalyst system showed higher NOx conversion. It is shown that the plasma by itself cannot chemically reduce N...

Climatic changes and the growing population call for innovative solutions that are able to produce biochemicals by adopting environmentally sustainable procedures. The biorefinery concept meets this requirement. However, one of main drawbacks biorefineries is represented feedstocks’ pretreatment. Lately, scientific research has focused on non-thermal plasma, which an pretreatment obtain a high ...

We report on the discovery of thermal and non-thermal X-rays from the shells of the super bubble (SB) 30 Dor C in the Large Magellanic Cloud (LMC). The X-ray morphology is a nearly circular shell with a radius of ∼40 pc, which is bright on the northern and western sides. The spectra of the shells are different from region to region. The southern shell shows clear emission lines, and is well fit...

In this paper we review the possible mechanisms for production of non-thermal electrons which are responsible for the observed non-thermal radiation in clusters of galaxies. Our primary focus is on non-thermal Bremsstrahlung and inverse Compton scattering, that produce hard X-ray emission. We first give a brief review of acceleration mechanisms and point out that in most astrophysical situation...

Mechanism of inactivation of bio-particles exposed to non-thermal plasma (NTP), namely, dielectric barrier discharge (DBD), and plasma jet (PJ), has been studied using E. coli, B. subtilis spore, S. cerevisiae and bacteriophages. States of different biological components were monitored during the course of inactivation. Analysis of green fluorescent protein, GFP, introduced into E. coli. or B. ...

The current work demonstrates the feasibility of atmospheric pressure non-thermal plasma technique for NOx pollution control. Atmospheric pressure dielectric barrier discharge plasma reactor has been constructed for the treatment of the exhaust of 4kWs free load diesel engine. The nature and properties of the discharge were identified through studying electrical characterization of the discharg...
