Lecturer Ali Fadhil Mohammed published a research paper titled “The Impact of Tube Diameter of Non-Thermal Atmospheric Pressure Plasma Jet on Producing Reactive Species” in the AIP Conference Proceedings journal, indexed in Q4. The research aimed to study the effect of tube diameter on the performance of a non-thermal atmospheric pressure plasma jet using argon gas and a dielectric barrier discharge system. Three different tube diameters (1.9, 3, and 6 mm) were tested to investigate their role in generating reactive species using optical emission spectroscopy (OES).
The study concluded that tube diameter plays a crucial role in the plasma discharge characteristics and the efficiency of producing reactive species. Emission intensity and generation efficiency increase as tube diameter decreases. Furthermore, increasing the diameter leads to a higher breakdown potential and plasma formation time. The study concluded that the engineering design of the plasma jet is important in improving its applications, especially in medical and biological fields that rely on the production of reactive species.
