Abstract

For low-temperature atmospheric pressure plasma treatment applications, we developed a novel rotating arc jet operated using various gases, including ambient air. We demonstrate the operation of plasma via the injection of various gas mixtures and tune operation parameters to achieve a low-temperature gas output from the arc jet. The rotating arc jet has an efficiency two orders of magnitude higher in the generation of reactive oxygen and nitrogen species than commercially available conventional nonequilibrium atmospheric pressure plasma jets operated with He or Ar gases. The high concentration of reactive species and use of ambient air as a process gas is promising for biomedical and agriculture applications. This work is a step toward the commercial use of plasma jets operated with ambient air.

Highlights

Atmospheric pressure plasma treatment has attracted a substantial amount of attention due to its many possible applications, such as cancer treatment, wound healing, seed germination, plant growth promotion and surface activation [1]–[10]
A major drawback of both dielectric barrier discharge (DBD) plasma and nonequilibrium atmospheric pressure plasma jets (NEAPPJs) is the low concentration of the produced reactive oxygen and nitrogen species (RONS), which play a key role in the bactericidal effect, wound healing, and plant growth promotion [5], [10], [11], [17]–[23]
The stable operation of the rotating arc jet (RAJ) was confirmed with various mixtures of Ar, N2, and O2 gases and ambient air; the discharge parameters should be adjusted for each gas mixture to ensure the stable rotation of the arc

Introduction

Atmospheric pressure plasma treatment has attracted a substantial amount of attention due to its many possible applications, such as cancer treatment, wound healing, seed germination, plant growth promotion and surface activation [1]–[10]. A major drawback of both DBD plasma and NEAPPJs is the low concentration of the produced reactive oxygen and nitrogen species (RONS), which play a key role in the bactericidal effect, wound healing, and plant growth promotion [5], [10], [11], [17]–[23]. Another important problem is the strict requirements placed on the injected gases and the experimental conditions during
