Methods for plasma stability in a plasma treatment tool are disclosed. A laser is positioned within a plasma treatment chamber within a skin depth of the electromagnetic field generated therein. The laser can be synchronized with the electrical triggering signals that generate the electromagnetic field. This scheme provides a stable and efficient method of plasma ignition.

A plasma device for treating surfaces, in particular surfaces of fabrics. In order to allow for better ease of handling, an elongate housing is provided which can be manipulated with one hand and in which a plasma source is arranged. The plasma source has a plateau surface that extends in the longitudinal direction of the housing and includes at least one electrode via which plasma can be dispensed onto the surface to be treated. A center of gravity M and a geometrical center G are located at a distance of less than 20 mm from one another.

Provided is a plasma device for applying a cold atmospheric plasma to a surface to be treated, in particular on textiles, leather and/or plastic fibers. The plasma device includes a housing, a plasma source in the housing, and a voltage source in the housing for applying a voltage to the plasma source, wherein the plasma device is configured to enable activation of the plasma source and/or to selectively switch the plasma source on only if a distance between the plasma source and the surface to be treated is within a predetermined distance.

A water-repellent coated boron nitride powder is disclosed. The powder can include a plurality of boron nitride particles and a water-repellent coating. The water-repellant coating can be chemically bonded to at least a surface of the boron nitride particles.

A method of manufacturing an artificial turf provides for moving a carrier mesh through an air gap formed between a first electrode and a second electrode of a dielectric barrier discharge device, applying a dielectric barrier discharge to a backside of the carrier mesh for plasma-based activation of the backside, and applying a backing layer to the plasma-activated backside of the carrier mesh for providing the artificial turf.

A measuring tube arrangement has two support bodies, each with at least one bore, and a measuring tube with a lumen for guiding a medium. The measuring tube has a first end portion and a second end portion which are each connected to one of the support bodies. The tube arrangement has a portion that is polished by forced electrolytic plasma polishing that extends over at least three diameters of the tube. The portion polished by forced electrolytic plasma polishing is followed by an etched portion having a different surface structure than the portion polished by forced electrolytic plasma polishing.

An apparatus for treating a substrate includes a support unit that supports the substrate and a nozzle that dispenses liquid plasma to etch a film formed on the substrate supported on the support unit.

A plasma generation device forms a patterned adhesive layer on a separation sheet surface and includes a roller part and plasma generator. The roller part includes a transfer roller for transferring the separation sheet and a metal member embedded in the transfer roller. The plasma generator includes a main body, electrode members, and a guide member. The main body is configured to be spaced from the transfer roller and elongated in a width direction perpendicular to a transfer direction of the separation sheet. The electrode members are disposed in the width direction and generate plasma on only a separation sheet surface disposed facing the metal member to form the patterned adhesive layer. The guide member fixes the electrode members to the main body and is detachably coupled to the main body to fix the electrode members to or separate the electrode members from the main body at the same time.

A method for the treatment, in particular for cleaning, reduction treatment and/or coating, of a workpiece, in which an atmospheric plasma jet is generated. A workpiece to be treated, in particular a workpiece to be cleaned, reduced and/or coated, is brought into contact with a liquid. A surface of the workpiece to be treated or the liquid is impinged with the atmospheric plasma jet. An apparatus for the treatment, in particular for cleaning, reduction treatment and/or coating, of a strip-shaped workpiece, in particular a metal strip, in particular for carrying out the afore-mentioned method.
