[ 1 ] - Molecular Effects of Atmospheric Pressure Plasma Jet on the Double-Stranded DNA

Introduction The aim of this study was toinvestigate the sterilization potential of atmospheric pressure plasma jet (APPJ) and interactions of this technology with double-stranded DNA using the polymerase chain reaction (PCR) and single-strand conformation polymorphism (SSCP) techniques. Materials and Methods The plasma jet was produced through a high voltage sinusoidal power supplyusing a mixt...

[ 2 ] - تولید و بررسی گوی پلاسمایی و تبدیل آن به جت پلاسمای فشار اتمسفری موج‌میکرو

In this work, we first produced microwave plasma ball, then changed the ball into a microwave plasma jet by flowing a working gas through a nozzle. The effect of working gas on the thermal characteristics of the plasma ball and atmospheric pressure microwave plasma jet was investigated. We used resonant absorption scheme by a metallic antenna inside a chamber in which led to the ionization of s...

[ 3 ] - طراحی و ساخت جت پلاسمای سه‌گانه سرد فشار اتمسفری و بکارگیری آن در استریلیزاسیون

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...

[ 4 ] - Design and implementation of high voltage square wave power source with variable DC-offset and study its effect on atmospheric-pressure plasma

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...
