  • Meso-and nanotubes
    Patent number: 6667099
    Abstract: The invention relates to mesotubes and nanotubes (hollow fibers) having an inner diameter of 10 nm-50 &mgr;m and to a method for the production thereof. The hollow fibers can be produced by coating degradable materials with non-degradable materials, whereby the degradable materials are destroyed by thermal methods, for instance. The hollow fibers are used in separation technology, catalysis, micro-electronics, medical technology, material technology or in the clothing industry.

  • Tubes having internal diameters in the nanometer range
    Publication number: 20030026985
    Abstract: Hollow fibers having an internal diameter from 1 nm to 100 nm can be produced by coating degradable materials with nondegradable materials and then degrading the degradable materials. The hollow fibers are useful in separation technology, catalysis, microelectronics, medical technology, materials technology or the clothing industry.
