Using laboratory data for the scattering of O by O2, CO and N2 pair potentials are constructed for O, C and N atoms. These potentials are then used to calculate collisional dissociation and energy transfer cross sections for O on O2, CO and N2; O2 on O2, N on N2, and N2 on N2. Since the energetic ions often neutralize in the atmosphere corona, such cross sections are relevant to plasma ion bomb...

since nox family, one of the most important causes of air pollution, is the primary source of acid rains, ozone layer depletion, and breathing disorders, mitigation of these pollutants is now a global concern. in the off-gases of internal combustion engines running with oxygen excess, non-thermal plasmas (ntps) have an oxidative potential, which results in an effective conversion of no to no2. ...

The role of low-pressure RF plasma in the inactivation of Escherichia coli O157, Klebsiella pneumoniae, Proteus mirabilis, and Enterobacter sakazakii using N2-O2 and SF6 gases was assessed. 1×109 colony-forming units (CFUs) of each bacterial isolate were placed on three polymer foils. The effects of pressure, power, distance from the source, and exposure time to plasma gases were optimized. The...

Small molecules like O2, N2 and CO are key species in the chemical evolution of preand protostellar cores. Since O2 and N2 do not have an electric dipole moment, direct observations of these spieces in cold environments are difficult. Gaseous N2 is known to be abundant in dense cores from indirect observations of the chemically related N2H + ion, but gas-phase O2 appears to be largely absent, w...
