Abstract: The disclosure deals with system/apparatus and corresponding and/or associated method for an open plasma reactor assembly provided to study pulsed reactive species produced in a dielectric barrier discharge (DBD) in He—H2O and He—H2O—O2 mixture in atmospheric conditions using photo fragmentation laser-induced fluorescence (PFLIF). The objective is to detect and quantify hydroxyl radicals and hydrogen peroxide produced in the DBD. An OH laser-induced fluorescence (LIF) signal is acquired from LIF (using 282 nm laser) whereas LIF from OH generated from H2O2 is measured by from the PFLIF signal (using 213 nm+ 282 nm lasers). A known concentration of H2O2 in He serves to calibrate for H2O2 while the OH is calibrated with a chemical model. For both gas mixtures, there is both OH and H2O2 production in the discharge, while the H2O2 concentration was noticeably increased for the added O2 case.

Abstract: Embodiments of the subject invention relate to a small modular self-contained surface plasma device for decontamination of air and surfaces within enclosed volumes. Embodiments of the subject invention relate to a method and apparatus using the technical process of dielectric barrier discharge (DBD) surface plasma generation from ambient atmosphere for decontamination of air and surfaces within enclosed volumes. The primary application mode is for preservation of perishable commodities within industrial shipping containers through reduction of surface spoilage organisms and destruction of evolved gaseous ethylene that causes premature ripening. Additional implementations include deployment for oxidation of surfaces and/or container atmospheres in applications to diminish or eradicate pesticides, toxins, chemical residues, and other natural or introduced contaminants. Other embodiments envisioned include incorporation of device capabilities and or ancillary modules for feedback input (e.g. ozone sensor(s) to maintain steady state levels, self-tuning circuitry to adjust operating frequency), communication (e.g. among modules, RFID data loggers, Wi-Fi output), and programing (e.g. user input of container volume, transit time, ozone level, etc.).

Abstract: A microwave-plasma system for generating fixed-nitrogen products comprises a microwave generator operably coupled with a gas chamber where the microwave generator provides microwave power to the gas chamber. The system further includes a source of gas, which may be for example oxygen, nitrogen and/or air, operably coupled with the plasma chamber. The microwave power produces a plasma of the gas within the chamber. The system further includes an absorber unit fluidically connected to the gas chamber to capture product from the plasma in the gas chamber. The captured product may include fixed nitrogen gaseous products.

Abstract: A linear flexible plasma generator having a function of cooling and temperature control. More efficient power control is possible, since a temperature of an electrode itself can be controlled in a state when plasma is discharged. In addition, since a temperature of the electrode surface can be decreased, use for the purposes of sterilization, neutralization, treatment, beauty treatment, and so on is possible.
