EHD-driven mass transport enhancement in surface dielectric barrier discharges

Surface Dielectric Barrier Discharges (S-DBDs) have received renewed attention in recent years for their potential application in emerging biomedical, environmental and agricultural applications. In most of these applications, the plasma is not in direct contact with the substrate being treated and...
