Abstract: The invention relates to a method for labelling a substrate, in which method at least one luminescent dye is deposited as a first identification feature in at least one transparent marker layer or in at least one functional layer on a surface of the substrate or on a layer which is situated on the surface, wherein the transparent marker layer or the functional layer is provided with a structure in a further step for producing a second identification feature by local destruction, in particular thermally. According to the invention, the deposition of the at least one marker layer or functional layer takes place by means of chemical gas-phase deposition using a flame or a plasma, by means of a sol-gel method or electrochemically.

Abstract: The invention relates to a hot melt adhesive, comprising at least one polysaccharide ester gained by a reaction of a polysaccharide with an imidazolide in melted imidazole. The invention relates, further, to a process for producing the hot melt adhesive, in which imidazole is melted, and an acid chloride and/or an acid anhydride and/or a lactone is reacted in and with the melted imidazole to form an imidazolide, whereby at least one polysaccharide is added to the melted imidazole, whereby the polysaccharide is reacted with the imidazolide to form a polysaccharide ester.

Abstract: The invention describes novel polymer-functionalized carbon nanotubes. These comprise a carbon nanotube, a first polymer that is adsorbed on the outer surface of a carbon nanotube and comprises amino groups, and a second polymer covalently bonded to the first polymer. The bond between the second polymer and the first polymer is formed by the reaction of amino groups from the first polymer with groups from the second polymer that are reactive with respect to amino groups. The invention further relates to a method for the production thereof, wherein carbon nanotubes are provided in an aqueous solution of a first polymer comprising amino groups and then a solution of a second polymer comprising groups that are reactive with respect to amino groups is added. The invention also relates to the use of the carbon nanotubes in dispersions, polymers and surface coatings.

Abstract: A modular and/or segmented magnetic bar for magnetron sputtering targets is provided. A magnet bar is made up of a plurality of magnet segments aligned in a substantially linear manner. One or more magnet bars may be provided. The positions of the magnet segments may be selectively adjusted to, for example, adjust magnetic field(s), replace magnet segment(s) that have been broken or damaged, and so forth.
