Atmospheric Pressure Plasmas in Resonant Circuits
This paper attempts to give a short overview of atmospheric pressure plasmas generated in very non-uniform radiofrequency electric fields. All these forms of gas discharges have a common characteristic: they are generated based on the possibility to obtain very high voltages in resonant series RLC circuits. The paper presents both the radiofrequency generators designed in this aim and some appl...
متن کاملPerspectives on atmospheric-pressure plasmas for nanofabrication
Low-pressure, low-temperature plasmas are widely used for materials applications in industries ranging from electronics to medicine. To avoid the high costs associated with vacuum equipment, there has always been a strong motivation to operate plasmas at higher pressures, up to atmospheric. However, high-pressure operation of plasmas often leads to instabilities and gas heating, conditions that...
متن کاملChemical Kinetics in Air Plasmas at Atmospheric Pressure
The chapter, after a general introduction concerning plasmas produced in air at atmospheric pressure, describes the chemical kinetics happening in the plasma gas-phase, focusing on the nitrogen oxides mechanism of formation and elimination. After a general review of the chemical kinetic pattern, we discuss dielectric barrier discharges and their use for NOx remediation. In fact, research concer...
متن کاملUltra-small photoluminescent silicon-carbide nanocrystals by atmospheric-pressure plasmas.
Highly size-controllable synthesis of free-standing perfectly crystalline silicon carbide nanocrystals has been achieved for the first time through a plasma-based bottom-up process. This low-cost, scalable, ligand-free atmospheric pressure technique allows fabrication of ultra-small (down to 1.5 nm) nanocrystals with very low level of surface contamination, leading to fundamental insights into ...
متن کاملInfluence of gas contaminant on the electron kinetic in microwave Ar plasmas at atmospheric pressure
Influence of nitrogen, oxygen and hydrogen traces in an atmospheric pressure argon surface-wave plasma was studied by mean of emission spectroscopy. The electron temperature and density were respectively shown to increase and decrease with an increased flow of gas contaminant, the trends being more significant in the case of oxygen. However, Ar 1s2 level number densities remained constant for a...
