Marcos Barela 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).

  • Fabrication of an anisotropic super hydrophobic/hydrophilic nanoporous membranes
    Patent number: 7393391
    Abstract: Anisotropic hydrophobic/hydrophilic nanoporous membranes and methods of forming anisotropic hydrophobic/hydrophilic nanoporous membranes are disclosed. The method of forming the nanoporous membrane includes growing a nanoporous oxide film on a substrate. A nanoporous membrane having a top side and a bottom side can then be formed by partially separating the nanoporous oxide film from the substrate. A fluorocarbon film can be deposited on the top side of the nanoporous membrane by plasma polymerization. The disclosed anisotropic hydrophobic/hydrophilic nanoporous membranes can have extremely different hydrophobicity between the top side and the bottom side of the nanoporous membrane.
    Type: Grant
