Demetrius VAZQUEZ-MOLINA 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).

  • Mechanically shaped 2-dimensional covalent organic frameworks
    Patent number: 11952393
    Abstract: Covalent organic frameworks (COFs) usually crystallize as insoluble powders and their processing for suitable devices has been thought to be limited. Here, it is demonstrated that COFs can be mechanically pressed into shaped objects having anisotropic ordering with preferred orientation between the hk0 and 00l crystallographic planes. Pellets prepared from bulk COF powders impregnated with LiClO4 displayed room temperature conductivity up to 0.26 mS cm?1 and stability up to 10.0 V (vs. Li+/Li0). This outcome portends use of COFs as solid-state electrolytes in batteries.
    Type: Grant
    Filed: October 21, 2022
    Date of Patent: April 9, 2024
    Assignee: UNIVERSITY OF CENTRAL FLORIDA RESEARCH FOUNDATION, INC.
    Inventors: Fernando Javier Uribe-Romo, Demetrius Vazquez-Molina, James K. Harper
