Abstract: A method for coating a component including the following steps: providing a gas phase containing at least one tetra-alkoxy silane as first silicon-containing precursor, at least one functionalised silicic acid ester with a phenyl, vinyl, allyl, thiol, amino, acryloxy, epoxy, nitrile, isocyanate, isothiocyanate or methacrylate group as second silicon-containing precursor, at least one catalyst, water and inert gas, the silicon-containing precursors being added in metered fashion to the gas phase separately from one another and separately from the water and the catalyst, chemically reacting the first silicon-containing precursor with water in the gas phase so ss to form first reaction products, chemically reacting the second silicon-containing precursor with water in the gas phase so as to form second reaction products, depositing the reaction products on the component. The reaction products of all precursors together form a coating on the component based on amorphous silicon dioxide.

Abstract: A bearing system having a bearing pair made up of at least one bearing and at least one running partner, wherein a coating which is made up of a layer of which the main constituent is amorphous SiO2 is applied to at least one running surface of the bearing pair.

Abstract: A process for the application of layers composed of ceramic or organoceramic materials on surfaces of metals, semimetals or compounds thereof and also components or assemblies made of these materials by a chemical deposition process from the gas phase at atmospheric pressure or 30% below this and process temperatures during deposition below 500° C. The deposition process is carried out in one operation, wherein the reactive chemical substances and the precursors are homogeneously backmixed in the common gas space, and the average residence time as a ratio of volume of the gas space to gas throughput is matched to the rate-determining step of the catalyzed gas-phase reaction of the coating process so as to achieve a deposition rate of from 10 to 2000 nm per hour.

Abstract: The invention relates to a process for preparing microspheres comprising an ionically crosslinked polymer, the process comprising: (a) producing liquid aerosol droplets (13) from a solution (3) comprising an ionically crosslinkable polyionic polymer into a continuous gas stream by using an ultrasonic nebulizer; (b) transferring the gas stream into a gelling solution (10) comprising di-, multi- or polyvalent ions, whereby crosslinked polymer microspheres (14) are formed, (c) separating the microspheres from the gelling solution, and (d) optionally, filtering the microspheres through a screen.

Abstract: Micromixer for mixing at least two fluids that react to form precipitations or suspensions, comprising a first channel for supplying a first partial flow and a second channel for supplying a second partial flow, which flows enter into a mixing and reaction area via narrow entrance gaps and leave via an outlet channel with reverse flow prevention being placed between the mixing and reaction zone and at least one channel that supplies a partial flow.

Abstract: Static lamination micro mixer comprising at least one slotted plate having slot openings and an aperture plate having aperture slots arranged above the slotted plate.

Abstract: The invention relates to a method for the production of a metallic pipeline with firmly adherent plastics sheathing, where, by means of a plasma treatment or by means of a gas-burner flame, an activated surface is generated on a metal pipe, where the exposure time of the surface is less than 3 seconds, and a plastics sheathing is applied to the activated naked surface of the metal pipe and, at the juncture of application of the sheathing, the temperature of the surface of the metal pipe is below 80° C.

Abstract: The invention relates to a micromixer for mixing at least two fluids that react to form precipitations or suspensions. The micromixer comprises a first channel for supplying a first partial flow (6) and a second channel for supplying a second partial flow (7). These flows empty into a mixing and reaction area (10) via narrow entrance gaps (19, 20) and leave the mixing and reaction area (10) via an outlet channel (11). The invention is characterized in that a reverse flow prevention is placed between the mixing and reaction zone (10) and at least one channel that supplies a partial flow (6, 7, 37).
