A method for sterilizing ambient air includes the steps of: a) installing a plasma-based smart window including an atmospheric pressure plasma device which includes first and second transparent flat patterned electrodes sandwiched between a light-transmissive substrate and a light-transmissive cover plate; and b) applying a power supply parameter of a predetermined magnitude between the first and second transparent flat patterned electrodes at ambient temperature and pressure to generate a surface plasma proximate to the light-transmissive substrate or the light-transmissive cover plate so as to inactivate microorganisms in the ambient air.

Adjustable distal tips of cold plasma generating devices configured for introduction to and operation within narrow intra-body confines. In some embodiments, a plasma delivery tip of a cold plasma generating device is expandable from a compact delivery configuration, allowing device operation with plasma plume parameters difficult to achieve within size constraints of a narrow delivery catheter and/or endoscope working channel. Additionally or alternatively, in some embodiments, operating parameters of a plasma delivery tip are adjustable to tune characteristics of the plasma plume. Adjustable parameters optionally include, for example: lumen diameter, lumen aperture shape/direction, discharge electrode geometry, dielectric barrier characteristics, and/or relative placement of these components, including placement relative to a stream of ionizing gas. In some embodiments, plasma delivery tip elements are adapted to assist device navigation and/or tissue penetration.

The invention relates to a method for treating an elongated object using a plasma process. The method comprises the steps of providing an elongated object in a planar electrode structure, and applying potential differences between electrodes of an electrode structure to generate the plasma process. Further, the method comprises at least partially surrounding the elongated object by a unitary section of the guiding structure, the electrode structure being associated with the unitary section.

The present invention relates to a plasma generating apparatus for a secondary battery. The plasma generating apparatus for the secondary battery comprises a roller part comprising a transfer roller that transfers a separator and a metal member built in the transfer roller, and a plasma generating part comprising a main body spaced apart from the transfer roller and a plurality of electrode members disposed on positions that are spaced apart from each other in a direction of both ends of the main body and partially generating a plasma between the metal member and the main body to form a patterned bonding layer on a surface of the separator, wherein the plurality of electrode members are detachably coupled to the main body to adjust a number of the electrode members coupled to the main body based on a size of the separator.

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 plasma rail device of the invention is a novel method and device to generate plasma right at the surface or slight above the surface for surface treatment, specifically for surface sanitization. The device generally comprises pairs of electrodes held together by a frame. The device features a fame that holds and positions the electrodes in a close proximity towards the surface under treatment. Discharges are created in the space bounded by the electrodes to generate plasma on the surface and above the surface for treatment so that the device can be positioned outside the object under treatment.

An electrode component for generating large area atmosphere pressure plasma is provided. The electrode component comprises a first transparent insulation substrate, a first transparent electrode pattern, a second transparent electrode pattern, and a second transparent insulation substrate. The first transparent insulation substrate has a first thickness. The first transparent electrode pattern and the second transparent electrode pattern are formed on the upper surface of the first transparent insulation substrate and has a gap therebetween. The second transparent insulation substrate has a second thickness and covers the first transparent electrode pattern and the second transparent electrode pattern. The first thickness is greater than the second thickness in order to form atmospheric pressure plasma above the second transparent insulation substrate.
