Abstract: Disclosed is a method for generating conductive surface patterns on a substrate by coating the substrate with a predetermined pattern of electrically conductive particles or of particles of a material that can be converted by heating into an electrically conducting material, and sintering or melting the coated substrate by means of electromagnetic radiation and by applying an antenna for said electromagnetic radiation in the vicinity of the predetermined pattern. The process is easy to implement, needs only low energy, is very fast and can be used to generate electrically conductive patterns at low cost.

Abstract: Disclosed are magnetic fluids containing ionic liquids and containing no stabilisation agents or containing selected stabilisation agents. These magnetic fluids can be used in different fields of industry, for example as an ink, as a damping fluid, as a sealing fluid, in imaging applications, in sink flotation techniques, in biomedical applications, as a reaction medium to perform chemical reactions, as a reversible seal for occluding blood vessels in living organisms in medical therapy or as a transportation means and/or delivery means for chemical substances at a selected location within a chemical or biological system.

Abstract: Disclosed are metal nanoparticle containing unimolecular micelles comprising selected star-shaped block-copolymers. These unimolecular micelles can be used as catalysts in coupling reactions forming carbon-carbon-bonds, for example as catalysts in the Heck reaction.
