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 is a method for generating surface patterns on a substrate by coating the substrate with a silver nitrogen complex and forming the metallic silver by treatment with a reducing agent for the silver nitrogen complex at least one of the coating steps providing a predetermined pattern on the surface of the substrate. The process is easy to implement and can be used to generate metal pattern at low cost and at low temperatures.
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 is a method for improving the characterization of reflecting surfaces of a sample by means of optical profilometry comprising the steps: i) providing a sample with at least one sample surface to be characterized by an optical profilometry method, ii) depositing at least one layer of a particulate material onto said sample surface to increase the diffuse reflectance of said sample surface, and iii) performing the optical profilometry method to characterize the sample surface. This method can be used in the analysis of manufactured micro-scale engineered parts, or in the characterization of microelectronic components, or to study samples of material of medical or of scientific relevance.
Abstract:
Disclosed is a method for generating a spatially addressably library of polymer particles. The method uses a direct-writing technique, such as inkjet printing, to cause the polymer to precipitate from a solution in a non-solvent thereof. By modification of chemical and/or physical parameters process-property relationships or formulation-property relationships of the particles formed can be studied with high efficiency.
Abstract:
Disclosed is a method for generating macroporous polymeric crosslinked materials and the materials obtained therewith. The method uses beads of reversible hydrogels or selected core-shell beads as pore forming materials which are introduced as solid beads into a liquid of polymerisable monomers, for example via a drop-on-demand technique. After the polymerisation of the monomers the solid beads are liquefied and the pore-forming material is removed from the polymer matrix. This technique allows formation of macropores with uniform diameter and with a high amount of macropores being in fluid communication with each other. The macroporous polymeric crosslinked materials, preferably in the form of hydrogels, can be used as substrates in tissue-engineering.

Abstract:
Disclosed is a method for generating photonically processed surface patterns on a substrate by inkjet printing the substrate with a photonically active material, for example of electrically conductive particles or of particles of a material that can be converted by irradiation into an electrically conducting material, and by treating the imprinted surface with actinic laser radiation which is emitted from a laser interconnected with the print head of the inkjet printer. The laser radiation causes the photonically curable material to become chemically and/or physically modified. The process is easy to implement, needs only low energy, is very fast and can be used to generate patterns of functional materials at low cost.
