Dielectric barrier discharge (DBD) plasma has several applications in different fields. One of these fundamental applications is medical usages, where various methods are employed to improve the plasma treatment process. The combination of different gases is one of the important strategies to improve the performance of plasma in treatment. In this paper, the optimized plasma […]
We present the results of experimental studies of the barrier negative corona of constant voltage excited by a metal tip over a metal plane covered by a thin film of polytetrafluoroethylene. It is shown that bright surface discharges – streamers – form on the dielectric surface as the voltage increases. The change in the surface […]
AbstractThis study was conducted to monitor the plant responses to seed priming with electromagnetic fields (0, 4, or 6 mT) or cold plasma (0, 80, or 100 s) in Salvia nemorosa. The cold plasma or electromagnetic field treatments significantly increased shoot fresh weight (49%), root fresh weight (41%), and root length (56%). The results highlighted that seed […]
AbstractPlasma as a rapidly evolving technology has been succeeded to widely exploit in various industrial fields. We attempt to address the short- and long-time effects of seed priming with cold plasma in Cichorium intybus. The seeds were subjected to plasma (dielectric barrier discharge). The post-reactions of the plasma-primed seedlings were monitored in response to different […]
AbstractA helium cold atmospheric pressure plasma jet (HCAPPJ) driven by a commercial neon power supply was designed and utilized for inactivation bacteria. The generated reactive spices by HCAPPJ were investigated by optical emission spectroscopy. The reactive species of OH, OI, OI, N21+, N21+ and He were identified in the UV–Vis wavelength region. The reactive species […]
AbstractAn analytical and numerical study is made on the dispersion properties of a cylindrical waveguide filled with plasma. An electron beam and static external magnetic field are considered as the mechanisms for controlling the field attenuation and possible stability of the waveguide. The effects of plasma warmness and inhomogeneity are also considered. Dispersion relations in […]
