Patents by Inventor Martin Graeser

Martin Graeser has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Production of metal nano- and mesofibers
    Patent number: 7981354
    Abstract: The invention relates to a method for producing metal oxide fibers with diameters on the micro- and nanometric scale by using electrospinning. At least one polymer is dissolved in a solvent, a metal salt is dissolved in this polymer solution, and this mixture is subsequently electrospun into fibers. Breaking down the polymer renders metal oxide fibers accessible that can be optionally reduced into the corresponding metal fibers.
    Type: Grant
    Filed: August 25, 2006
    Date of Patent: July 19, 2011
    Assignee: Philipps-Universitat Marburg
    Inventors: Joachim H. Wendorff, Andreas Greiner, Michael Bognitzki, Martin Graeser

  • Thermoelectric Nanomaterials
    Publication number: 20090004086
    Abstract: The present invention relates to processes for producing nanowires and nanotubes by treating a fiber comprising at least one support material and at least one thermoelectrically active material or a precursor compound of a thermoelectrically active material, to a nanowire comprising at least one thermoelectrically active material and having a diameter of ?200 nm and a length of ?1 mm, to nanotubes comprising at least one thermoelectrically active material and having a diameter of ?200 nm, a wall thickness of ?30 nm and a length of ?1 mm, and to the use of the nanowires or nanotubes for thermoelectric heating, for electricity generation, in sensors or for temperature control.
