Fig 1. Different plasma devices.

A. Schematic view of the helium plasma jet device on the right side and picture during the generation of plasma activated water inside a glass beaker using the helium plasma jet and a magnetic stirrer. B. Schematic view of the floating electrode-dielectric barrier discharges (FE-DBD) in air showing the powered electrode covered by glass (in blue colour) with seeds in ambient air plasma above the lamella (right side) and picture displaying the air plasma over the glass lamella.
