Low temperature plasma, compared to liquid phase treatment, can effectively overcome the environment pollution, high energy loss and high cost as its high activity. The low temperature plasma, which is not only fairly friendly to the environment but also of less resource consumption, also can realize the cleaning, activating and grafting treatment for materials surface. Based on the numerical model of CRFHCP (Capacitive Radio Frequency Hollow Cathode Plasma) hollow cathode plasma discharge, the key point to affect plasma discharge was analyzed and the morphology of PP film before and after hollow cathode plasma discharge was analyzed. The results showed that the structure of plasma hollow cathode discharge can effectively improved the chemical behaviors of PP film.

Abstract The work is devoted to the study of a low-temperature plasma jet of atmospheric pressure in a mixture of air with argon, used in plasma medicine. The intensities of the spectral emission bands of OH– (309 nm), N2 (337 nm), and N2 (356 nm) in different parts of the plasma jet were investigated depending on the argon flow rate and the amplitude of voltage pulses at the electrodes of the dielectric barrier discharge. The antibacterial effect of such a plasma jet on the surface of biological tissues has been experimentally investigated. Numerical simulation of ionization processes in the studied plasma source has been performed in the COMSOL Multiphysics software using. The dynamics of the distribution of excited molecules in the plasma torch as well as the kinetic plasma processes inside the plasma torch affecting the spatial distribution of its main characteristics have been analyzed.

The One

This paper reviews the principles behind the design and operation of the resistive barrier discharge, a low temperature plasma source that operates at atmospheric pressure. One of the advantages of this plasma source is that it can be operated using either DC or AC high voltages. Plasma generated by the resistive barrier discharge has been used to efficiently inactivate pathogenic microorganisms and to destroy cancer cells. These biomedical applications of low temperature plasma are of great interest because in recent times bacteria developed increased resistance to antibiotics and because present cancer therapies often are accompanied by serious side effects. Low temperature plasma, such the one generated by the resistive barrier discharge, is a technology that can help overcome these healthcare challenges.

AbstractA compact source of low-temperature plasma for biological and medical applications is proposed, which operates at kilohertz frequencies in the regime of flash-corona discharge with an energy of 0.1 mJ/pulse. The plasma source was tested in application to plasma pretreatment of green salad seeds. Plasma-treated seeds exhibited increased (by about 25%) germination speed as compared to that in the untreated control.
