Patents by Inventor Mark Tuominen

Mark Tuominen 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).

  • Patent number: 8519074
    Abstract: Polymers including pendent hydrophobic groups and pendent proton transfer groups are shown to form nanostructured films exhibiting greatly increased proton conductivity compared with films prepared from corresponding polymers lacking hydrophobic groups. The polymers can include repeating units each of which has both a hydrophobic group and a proton transfer group. Alternatively, the polymers can be the product of copolymerizing a first monomer with at least one hydrophobic group and a second monomer with at least one proton transfer group. The polymers are useful for the preparation of fuel cell proton exchange membranes.
    Type: Grant
    Filed: December 21, 2010
    Date of Patent: August 27, 2013
    Assignee: The University of Massachusettes

  • Patent number: 7572669
    Abstract: Pathways to rapid and reliable fabrication of nanocylinder arrays are provided. Simple methods are described for the production of well-ordered arrays of nanopores, nanowires, and other materials. This is accomplished by orienting copolymer films and removing a component from the film to produce nanopores, that in turn, can be filled with materials to produce the arrays. The resulting arrays can be used to produce nanoscale media, devices, and systems.

  • Publication number: 20070200477
    Abstract: Pathways to rapid and reliable fabrication of three-dimensional nanostructures are provided. Simple methods are described for the production of well-ordered, multilevel nanostructures. This is accomplished by patterning block copolymer templates with selective exposure to a radiation source. The resulting multi-scale lithographic template can be treated with post-fabrication steps to produce multilevel, three-dimensional, integrated nanoscale media, devices, and systems.
