DIELECTRIC BARRIER DISCHARGE PLASMA SYSTEM AND METHOD FOR IN-SITU HYDROGEN PEROXIDE PRODUCTION
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—H.sub.2O and He—H.sub.2O—O.sub.2 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 H.sub.2O.sub.2 is measured by from the PFLIF signal (using 213 nm+ 282 nm lasers). A known concentration of H.sub.2O.sub.2 in He serves to calibrate for H.sub.2O.sub.2 while the OH is calibrated with a chemical model. For both gas mixtures, there is both OH and H.sub.2O.sub.2 production in the discharge, while the H.sub.2O.sub.2 concentration was noticeably increased for the added O.sub.2 case.

Nanoparticle synthesis apparatus
Nanoparticles are synthesized by suctioning a liquid under a negative pressure with a negative-pressure suction force caused by the rotation of a rotary blade, causing cavitation by stirring the suctioned liquid by the rotary blade, generating plasma generated by a plasma generation mechanism in air bubbles generated in the liquid, and in that case, consuming an electrode containing elements constituting the nanoparticles to be synthesized.
