Disclosed are systems, methods, and devices for generating radicals in an air stream at the intake of an internal combustion engine, as well as increasing the thrust of such air streams into the engine. A plasma generator including plasma actuators, dielectric barrier discharge electrodes, or both is positioned in the intake stream. Plasma actuators are disposed on the interior surface of the plasma generator, exposed to the intake stream. Dielectric barrier discharge electrodes protrude into the intake air stream. Plasma, preferably DBD plasma, glow plasma, or filamentary plasma, is generated in the air intake stream, creating radicals in the stream, mixing the radicals in the stream, and reducing drag while increasing thrust of air in the intake stream. A concentric cylinder can be further disposed in the plasma generator, with further plasma actuators, dielectric barrier discharge electrodes, or both, on the interior and exterior surfaces of the cylinder.

The present invention relates to a plasma generating apparatus for a secondary battery. The plasma generating apparatus for the secondary battery comprises a transfer roller that transfers a separator, a metal member disposed within the transfer roller, a plasma generating member that interacts with the metal member to generate a plasma and irradiate the generated plasma onto a surface of the separator, and a protrusion member that causes a portion of the separator closely attached to the transfer roller to protrude and forms an adhesion area, which is adhesive, and a non-adhesion area, which is non-adhesive or less adhesive than the adhesion area, by allowing the plasma to be irradiated onto the adhesion area and no plasma or less plasma to be irradiated onto the non-adhesion area.

The present invention relates to the technical field of ionizing a gaseous substance, in particular the ionizing or ionization of a gaseous substance in preparation for its analysis. A device is intended to make a discharge gas and a test substance ionizable in a flow-through mode without essentially destroying or fragmenting the sample substance. In order to avoid a high expenditure in terms of construction and equipment, the device is intended to be usable under ambient conditions and to ensure a high sensitivity in a possible analysis of an ionized substance. To this end, an ionizing device is used for flow-through ionization of a discharge gas and of a sample substance at an absolute pressure of more than 40 kPa in the ionizing device during ionization. The ionizing device comprises an inlet, an outlet, a first electrode, a dielectric element and a second electrode. The dielectric element is configured in the shape of a hollow body having an inner side and an outer side and it allows a flow of the discharge gas and of the sample substance therethrough in a flow direction. The first electrode is arranged outside of the outer side of the dielectric element. The second electrode is arranged, at least sectionwise, inside the dielectric element, is surrounded by the inner side of the dielectric element perpendicularly to the flow direction, and allows a flow of the discharge gas and of the sample substance therethrough or therearound. A distance in or contrary to the flow direction exists between the associated ends of the first and second electrodes and lies between 5 mm to 5 mm. A dielectric barrier discharge is establishable in a dielectric barrier discharge region by applying a voltage between the first and second electrodes so as to ionize the discharge gas or the sample substance.
