Processes in Atmospheric Pressure Plasmas

Dear Colleagues,

Different types of atmospheric-pressure plasma are applied not only in classical fields, such as material research, diagnostics, or industrial production, but also in novel approaches in food and seed science and medicine, including wound healing, dentistry, sterilization, odor control, and many others. The most frequently used methods for atmospheric pressure plasma generation include:

• Different atmospheric-pressure plasma jets based on kHz DBD, radio frequency, microwaves, and pulsed arcs, operated with different gases.
• Dielectric barrier discharges, including surface barrier discharges, coplanar surface barrier discharges, and atmospheric-pressure glow operated with noble gases or their mixtures with oxygen or hydrogen.
• Piezoelectric direct discharge, used both in ambient air and in the wall-specified gas mixtures of nitrogen, oxygen, synthetic air, or compressed dried air.
• Corona discharges, especially positive pulsed corona.

A focus of recent research is the interaction of plasma with liquids or humid environments, including the production of plasma-activated water (PAW) or plasma-activated liquids in general. Despite progress in this area, the mechanisms of interaction of different types of plasma with humidity, liquids, and materials are not fully understood in all cases. Many physical and chemical processes crucial for successful implementation require better explanations, modelling, predictions, and clarifications. This Special Issue of Plasma presents an opportunity for both scholars and researchers from various national and international institutions to present their progress in these fields. You are welcome to submit your original papers for peer review

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Plasma is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
