  • Publication number: 20130295369
    Abstract: A three-dimensional molded body, a method for producing a three-dimensional molded body and a method for producing an adhesive bond between a polymer-containing material and a molded body having an inorganic porous framework structure in at least partial areas are described. In all cases the porous structure of the molded body comprising inorganic material is brought in contact with a polymer-containing material which is heated until the heated material enters into a joint connection with the molded body based on adhesive interactions, interfacial interactions, electrostatic interactions or any combination thereof, in which the pore-like voids of the porous structure are filled completely with the polymer-containing material, which stabilizes the molded body so that it has dimensional stability after cooling.

  • Publication number: 20060119015
    Abstract: The invention relates to a method for producing hollow fibres, in particular for producing meso- and nanotubes, whose tubes or hollow fibres have an internal diameter in the nano- to micrometre range and are preferably aligned in one direction. The invention also relates to the use of said hollow fibres, to hollow fibres or tubes produced by said method and to composite materials containing the hollow fibres or tubes.

  • Publication number: 20040069948
    Abstract: The invention relates to a method for the analysis of the qualitative and/or quantitative composition of fluids with at least one light source, one interaction space area in which the light interacts with the fluid, and one detection device for detecting the interaction between the fluid and the light. The device and the method are characterised in that a photonic the gap structure is provided creating a greater reduced group velocity in the interaction space area and thus an increased dwell time for the light in the interaction space area. This means that the interaction space area can be considerably reduced in size, which allows a compact design of the device.
