Micro-dielectric barrier discharges (mDBDs) are known for being stable, high-pressure and non-thermal plasma sources. mDBD arrays consist of micro-plasma devices (10–100μm) in which the radio frequency (rf)-excited electrodes are covered by dielectrics. In certain applications, independent control of individual mDBDs in an array is required for charge extraction to treat dielectric surfaces. Wh...

Atmospheric pressure dielectric barrier discharge (DBD) plasma can be used to split low molecular weight organic compounds, and the DBD-split/excited species can be swept into luminol solution to induce chemiluminescence (CL) emission. Based on this observation, a novel optical detector was proposed and preliminarily tested as a potential gas chromatographic (GC) detector in this work. The adva...

Applications of Thomson scattering diagnostics to two kinds of dielectric barrier discharge (DBD) plasmas are presented. One is that for the plasma display panel. In order to avoid laser perturbations for Xe containing discharges which are easily disturbed by laser beams with visible wavelengths, a laser Thomson scattering (LTS) system having an infrared laser (wavelength 1064 nm) as a light so...

A dielectric barrier discharge (DBD) produces a homogenous discharge with low energy consumption, offering broad developmental prospects, and this discharge process is also the mechanism through which charges are transported. Higher reaction efficiency is achieved when more charges are transported. Focusing on the electrode configuration of the multineedle-to-cylinder (MC) system, i.e., the str...

Solutions of ribose, glucose, and sucrose in water and phosphate buffer were treated with non-thermal plasma generated by using a dielectric barrier discharge (DBD) device and the oxidation products were characterized by H NMR and GC–MS. Our results demonstrate that these sugars are decomposed to formic acid, glycolic acid, glyceric acid, tartronic acid, tartaric acid, acetic acid, and oxalic a...

Glow discharge at atmospheric pressure using a dielectric barrier discharge can induce fluid flow, and operate as an actuator in flow control. In the present work, a modeling framework is presented to study the evolution and interaction of such athermal non-equilibrium plasma discharges in conjunction with low Mach number fluid dynamics. Under atmospheric pressure, the discharge can be simulate...

In this paper, a review on microplasma discharges is conducted. The different types and configurations used in microplasmas such as the Cathode Boundary Layer (CBL), Dielectric Barrier Discharge (DBD), Capillary Plasma Electrode Discharge (CPED), Inverted Square Pyramid (ISP), Square Cross Sectional Cavities (SCSC), Radio Frequency Inductively Coupled Discharge (RFIC), Radio Frequency Capacitiv...

An asymmetric dielectric barrier discharge model is presented for real gas eight species air chemistry using a self-consistent multi-body system of plasma, dielectric and neutral gas modeled together to predict the electrodynamic momentum imparted to the working gas. The equations governing the motion of charged and neutral species are solved with Poisson equation on finite elements using a Gal...
