in this paper, construction of triplet atmospheric plasma jet using argon, air, oxygen and nitrogen gases is reported. bactericidal effect of the plasma jet is also investigated. to that end, longitudinal geometric configuration for the electrodes was chosen because it would increase the jet length. electrical characteristics, jet length dependencies on the applied voltage and gas flow rate wer...

atmospheric pressure plasma (app) is an emerging non thermal technology for the improvement of food  safety. non-thermal plasma (ntp) is a neutral ionized gas that comprises highly reactive spices including, positive ions, negative ions, free radicals, electrons, excited or non excited molecules and photons at or near room temperature. ntp can be generated at atmospheric pressure that makes it ...

Mycotoxins such as Citrinin are small toxic molecules produced by a great variety of microorganism, which encompass several classes of secondary metabolites with no common chemical structure or mode of action. Citrinin produces by different species of Penicillium. Today, the cold atmospheric pressure plasma (CAPP) method has a potential for mycotoxin detoxification. In this study, a new and pro...

Cold atmospheric plasma (CAP) has received great attention due to its noteworthy ability, and has also been widely studied over few decades in physics, biology and medicine. The purpose of this study is to evaluate the cold atmospheric pressure plasma effects on the proliferation of breast cancer cells. MDA-MB-231 was used for this experiment. MDA-MB-231 cells were cultured in 24-well plate and...

  Methane conversion to higher hydrocarbons by pulsed glow discharge at the atmospheric pressure was investigated. The energy efficiency up to 10 % was obtained which is higher than any value ever published for nonequilibrium plasma conversion of pure methame. This method has a potential for development and it is expected that the energy efficiency will be improved further if the plasma paramet...

Nowadays high-voltage power sources is used in different areas such as generation of atmospheric-pressure plasma. Different voltage waveforms affect the plasma generation and its quality. In this paper a new high voltage square wave with DC-offset power source is presented to study the different parameters on plasma generation and propagation. The proposed converter which is based on power semi...
