Summary form only given. The fundamentals on the propagation of the atmospheric pressure plasma jets are not yet well understood. Teschke et al (2005), Lu et al (2006, 2008), Sands et al (2008), Shi et al (2008), and Ye et al (2008) studied the dynamics of the various plasma jets generated by different devices and sustained by different driving voltages. They all found that the plasma plumes are not...
Summary form only given. For root canal disinfection, the principal methods include mechanic cleaning, irrigation, laser irradiation, ultrasound, application of hypochlorite, and other anti-bacterial compounds. Clinic studies show that there are about 10% of treatment failures when the traditional disinfection methods are used. The failures are mainly due to the presence of bacteria, which can't be...
Terahertz generation from gaseous media was further investigated by a gas jet system. The experimental results reveal that the terahertz radiation amplitude is correlated with the third order nonlinear susceptibility.
Summary form only given. One of the attractive characteristics of nonequilibrium plasmas is their enhanced plasma chemistry without the need for elevated gas temperatures. This is because the plasma chemistry is driven by the energetic electrons, while the heavy particles remain at low energy. To enhance the gas chemistry, the electron energy distribution function can be controlled in a way to shift...
Summary form only given. Atmospheric pressure non-thermal plasmas have recently received increased attention because of several emerging applications. Recently, we presented a novel method to produce a non-thermal, large volume, atmospheric pressure plasma. This method used a similar configuration to the dielectric barrier discharge. However, instead of a dielectric, a resistive layer was used to...
