Effects of vibrationally excited N2 molecules on dielectric breakdown properties of SF6-N2 mixtures

Electron-impact resonant vibrational excitation and dissociation processes involving vibrationally excited N2 molecules

Resonant vibrational excitation cross sections and the corresponding rate coefficients for electron–N2 collisions occurring through the N − 2 (X 2 g) resonant state are reviewed. New calculations are performed using accurate potential energy curves for the N2 electronic ground state, taken from the literature, and for the N2 resonant state, obtained from R-matrix calculations. The calculations ...

Lifetime effects on the dissociation of core-excited N2 and CO molecules

Inactivation of Gram-Negative Bacteria by Low-Pressure RF Remote Plasma Excited in N2-O2 Mixture and SF6 Gases

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...

Temperature Rise Comparison of Switchgear in SF6, N2, and Air

Based on the heat conduction equation, fluid flow governing equation and radiation heat transfer equation, a multi-physics coupled mathematical model is established, the convection heat transfer problem between solid and fluid is solved by wall function. The three dimensional thermal field in a type of switchgear filled respectively with SF6, N2, and air are calculated and analyzed to discuss t...

Photodissociation dynamics of vibrationally excited CH2Cl2 molecules

Photodissociation of dichloromethane excited to the second C–H stretch overtone was performed by 235 nm photons that also tagged the Cl P3=2 [Cl] and spin–orbit excited Cl P1=2 [Cl ] photofragments via resonantly enhanced multiphoton ionization. The measured time-of-flight profiles together with the determined Cl /Cl branching ratio suggest fast dissociation and involvement of several upper sta...
