HMOS Sensing of Oxidizing Species in an Atmospheric Plasma Jet

Simulation of a Helium Atmospheric Plasma Jet Using Fluid Equations

In this study, a cold atmospheric He plasma jet is investigated. The jet is of dielectric barrier discharge type, consisting of a dielectric tube with two metal ring electrodes. The continuity, momentum and energy conservation equations as well as the Poisson equation for obtaining the potential and the electric field, accompanied with the ideal gas laws, are used for the simulation. The result...

Electron properties in an atmospheric helium plasma jet

In this work we present Thomson scattering measurements on a nanosecond pulsed high voltage dielectric barrier discharge (DBD)-like helium plasma jet, operated in ambient air. With the low detection limit offered by a triple grating spectrograph equipped with a high quantum efficiency intensified charge-coupled device (ICCD) camera, temporally and spatially resolved electron densities and mean ...

Cold atmospheric plasma jet in an axial DC electric field

Atmospheric Pressure Plasma Jet as an Accelerator of Tooth Bleaching.

OBJECTIVE To study the effect of atmospheric pressure plasma (APP) jet as a potential accelerator of the degradation of hydrogen peroxide in bleaching gels which could lead to better and faster bleaching. MATERIAL AND METHODS 25 pastilles of hydroxylapatite were colored in green tea for 8 hours and were randomly divided into five groups (n = 5). The bleaching process was performed with 30% an...

Aiaa 99-3604 Diagnostics of an Atmospheric Pressure Plasma Jet

Broadband ultraviolet absorption spectroscopy is employed to measure absolute number density of C2 and CH radicals in the boundary layer of an atmospheric DC plasma assisted chemical vapor deposition (CVD) system. High spatial resolution (125 μm) is achieved by using a spatial filter and a ultra-bright argon mini-arc light source. The spectra of D Σu←X Σg electronic transition of C2 and C Σ←X ∏...
