High pressure non-thermal plasma decomposition performance for low density, typically 250 ppm, volatile organic compounds (VOCs), mostly trichloroethylene, in synthesized air was examined for various conditions. In order to improve the VOCs decomposition energy efficiency of the plasma reactor, new manganese-dioxide supported alumina spheres were examined, where that catalyst works well to deco...

Low-temperature plasma has exhibited high efficiency for fast remediation of organic-polluted soil with water content (less than 20%). In the present study, the feasibility of remediation of p-Nitrophenol (PNP) contaminated over-wet soil (water content of 100%) was studied using pulsed corona discharge plasma, which was generated in a needle-plate discharge reactor. Effect of energy input model...

The inductively coupled RF discharge is known to exhibit two modes of operation depending on the level of incident power. Dominant capacitive coupling (E-mode discharge) occurs at low-power level while at high power, dominant inductive coupling (H-mode discharge) is obtained. In this work, we investigate the characteristics of the E-mode and H-mode discharges generated in a planar coil inductiv...

Abstract Plasma-induced defects are often recognized in state-of-the-art semiconductors, high-efficiency solar cells and high-sensitivity image sensors. These the form of a dangling bond, bond deformation, or impurity/residual, which impacts on device performance reliability. The introduced via plasma-material interactions during manufacturing processes such as deposition, etching implantation....

Plasma remediation is being investigated for the removal of oxides of nitrogen (NxOy) from atmospheric pressure gas streams. In previous works we have investigated the plasma remediation of NxOy from N2 /O2 /H2O mixtures using repetitively pulsed dielectric barrier discharges. As combustion effluents contain large percentages of CO2, in this paper we discuss the consequences of CO2 in the gas m...

The air pollutions from combustion flue gas and industrial gases became worse and cause the environmental problem. It is difficult for the conventional methods such as selective catalytic reduction method and lime-gypsum method to treat exhaust gases energy efficiently and inexpensively. Its energy efficiency and its initial and running costs are still in negative situation for the backward nat...

The measurement of β -decay rates in plasma, simulating stellar-like conditions, is high interest for the investigation radionuclides involved nuclear astrophysics processes. In new PANDORA plasma trap, to be built at INFN—Laboratori Nazionali del Sud Catania (Italy), will estimated by detecting γ -rays emitted daughter nuclei trapped confined plasma. present work describes efficiency High Puri...

The Rosenbluth form for the collision operator for a weakly relativistic plasma is derived. The formalism adopted by Antonsen and Chu can then be used to calculate the efficiency of current drive by fast waves in a relativistic plasma. Accurate numerical results and analytic asymptotic limits for the efficiencies are given.

August 2010 Volume 10, Issue 4 T he serotonin transporter (SERT) on platelets is a primary mechanism for serotonin (5HT) uptake from the blood plasma. Alteration in plasma 5HT level is associated with a number of cardiovascular diseases and disorders. Therefore, the regulation of the transporter’s activity represents a key mechanism to stabilize the concentration of plasma 5HT. There is a bipha...

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...
