Comprehensive Insights into Atmospheric Pressure Plasma Jets: Design, Operation, and Applications

Atmospheric pressure plasma jets (APPJs) have garnered significant attention due to their ability to generate reactive species at low gas temperatures, making them suitable for a wide range of applications, including surface treatments, food decontamination, plasma medicine, and water treatment. Despite their relatively simple design, APPJs exhibit complex behavior characterized by multiple physical and chemical mechanisms operating across various spatial and temporal scales, typical of non-thermal plasma devices. Recent studies have employed experimental characterization and numerical simulations to elucidate the underlying physical mechanisms, thereby enhancing the effectiveness and expanding the spectrum of applications for these devices. However, there remain gaps in our understanding of the fundamental aspects of APPJ operation, particularly in the context of their interaction with different materials and environments. Addressing these gaps is crucial for advancing the field and optimizing the use of APPJs in diverse applications.

This Research Topic aims to provide a comprehensive overview of the current state of the art in the design, construction, operation, and characterization of atmospheric pressure plasma jets, from both experimental and modeling perspectives. The primary objectives include answering specific questions related to the fundamental physical and chemical processes governing APPJ behavior, testing hypotheses about their interaction with various materials, and exploring new applications. By doing so, the research seeks to bridge existing knowledge gaps and foster a deeper understanding of APPJs, ultimately contributing to their broader and more effective utilization.
