Abstract: The 3D printing method disclosed here for the production of vascularized tissues and organs requires a droplet printer to produce photorealistic high-resolution prints and a device for applying non-directional or directional electromagnetic waves. The process uses a new type of capillary ink that crosslinks or undergoes a layer-forming reaction only in the edge area of the ink drops. Unbound capillary ink components are removed. The resulting cavities form a capillary network with diameters of up to approx. 10 ?m. Also disclosed is a novel printer table for supplying the printed tissue with medium during printing and a printer head supply unit for individually mixing the bio-inks from cell concentrate and various ink concentrates.

Abstract: A method for recycling powdered paint waste is provided in which, the powdered paint waste is being treated with the aid of a reactant in such a way that its adhesion to surfaces and especially to metal surfaces is reduced or eliminated. The treatment of the powdered paint waste allows the powdered paint waste to be additionally processed under the influence of heat and to use it as a starting material in various recycling processes or in other processes.

Abstract: A method for rendering material surfaces inert is provided. Exemplary surfaces include ceramic, metal or plastic surfaces. The method is accomplished with functionalized perfluorinated compounds for the formation of hyperhydrophobic structures on the surfaces to create inert surfaces. The inert surfaces produced or can be produced in this way have an extremely low surface energy, are resistant to deposits of substances or cells and have a very low coefficient of friction. Practical uses of the inert surfaces are also provided.

Abstract: An oligonucleotide or a nucleic acid covalently bonded to a perfluorocarbyl group has general formula ABE. A is a perfluorocarbyl group, including perfluorinated straight or branched aliphatic alkanes, perfluorinated straight or branched alkenes, perfluorinated straight or branched alkynes, and cyclic, optionally aromatic, perfluorocarbons, in which all of the H-atoms are substituted by F-atoms. B is a covalent bond, such as a covalent bond between the perfluorocarbyl group A and a C atom at the 2? position of one or more sugars of the oligonucleotide or the nucleic acid, a covalent bond between the perfluorocarbyl group A and a C atom of a heterocyclic ring of one or more nucleobases of the oligonucleotide or the nucleic acid, or a covalent bond between the perfluorocarbyl group A and an O atom of one or more phosphate groups of the oligonucleotide or the nucleic acid. E is an oligonucleotide or a nucleic acid.

Abstract: A method for fixing images in plastic moldings which allows images to be fixed in a plastic molding in such a way that the image is embedded therein and does not experience lasting changes, even for elastic plastic moldings. To avoid loss of image quality when the image is transferred into the plastic molding, the method for fixing images in plastic moldings after generating an image on an adhesive layer is characterized in that an image receptor layer of liquid plastic is applied to the image which, with or without an additional carrier, is generated on the adhesive layer. Components of the adhesive layer are at least partially miscible with the liquid plastic when it is applied. The liquid plastic phase is then converted to a solid plastic phase.
