Development Of Atmospheric Pressure Plasma Jet In Air

Abstract

In this paper, an atmospheric pressure plasma jet (APPJ) in air that is expected to be useful for polymer surface modification has been reported. The plasma jet was produced by applying (10 30) kHz, (0 20) kV AC source. The electrical and optical measurements have also been reported. The use of solenoid as an external electrode has been found to be more effective in boosting the jet to a distance up to 30 mm even with a small flow rate of air. The characteristic of the proposed APPJ was investigated by measuring the effect of treatment on a PE film on the jet for different exposition time and distance from the nozzle. It has been confirmed that the jet can modify polymer film with a work distance of over 25mm. This plasma jet can be useful for the treatment and cleaning of objects having large structures and could be used in wider areas of application. Keywords: APPJ, PE film, Air INTRODUCTIONIn the last one decade, the atmospheric pressure cold plasma research is highly increased due to its important applications in various fields. These types of plasma are non-equilibrium systems, where electron temperature is much higher than ion temperature. Atmospheric plasma cold plasma treatment of materials is a promising technology that is simpler to set-up, easier and economical to operate and does not require vacuum equipments.

Impact of plasma irradiation on Tribolium castaneum

“…In addition, it involves few variables and has comparably low equipment costs. Therefore, atmospheric plasma operations have been extensively studied and its applications have gradually increased in various fields due to its appreciated economic efficiency (Tyata et al 2012). In order to ensure its efficient adoption as a disinfestation treatment at industrial level as a safe and reliable alternative approach compared to ionizing radiation, significant research effort is still needed.…”

“…Furthermore, plasma treatment of wheat grains caused effective decontamination of bacteria and fungi together with insect pests and also enhanced the shelf life, germination and initial state of growth of the grains and resulted in an increased final grain yield. Moreover, the production of qualitatively better dough was also observed (Scholtz et al 2019;Tyata et al 2012). In this context, it was aimed to investigate the susceptibility of T. castaneum to radio frequency-induced cold atmospheric plasma (RFP) as an alternative pest control method with the following main objectives, (1) Confirm the efficacy of RFP as a killing method (2) Determine the sensitivity profile of different developmental stages exposed to different RFP doses using two different precursor gases.…”

Assessment of the potential of non-thermal atmospheric pressure plasma discharge and microwave energy againstTribolium castaneumandTrogoderma granarium

“…Non-thermal atmospheric pressure plasma discharge (APPD) is a specific type of plasma that is <40°C at the point of application (Nasr et al ., 2020). The non-thermal atmospheric pressure plasma is a promising technology that is simple to set up, easy to operate and economical and it can be considered a safe physical method for the disinfection of agricultural products after harvest (Tyata et al ., 2012). As a processing environment, non-thermal APPD offers unique advantages of high chemical reactivity, low power consumption, high energy efficiency and low gas temperature without the need for complicated vacuum systems (Zhou, 2019).…”
