Mark P. HENDRICKS 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).

  • Methods of producing metal sulfides, metal selenides, and metal sulfides/selenides having controlled architectures using kinetic control
    Patent number: 10767112
    Abstract: The present invention is directed to methods of preparing metal sulfide, metal selenide, or metal sulfide/selenide nanoparticles and the products derived therefrom. In various embodiments, the nanoparticles are derived from the reaction between precursor metal salts and certain sulfur- and/or selenium-containing precursors each independently having a structure of Formula (I), (II), or (III), or an isomer, salt, or tautomer thereof, where Q1, Q2, Q3, R1, R2, R3, R5, and X are defined within the specification.
    Type: Grant
    Filed: January 15, 2016
    Date of Patent: September 8, 2020
    Assignee: The Trustees of the Columbia University in the City of New York
    Inventors: Jonathan S. Owen, Mark P. Hendricks, Michael P. Campos, Gregory T. Cleveland, Ilan Jen-La Plante, Leslie Sachiyo Hamachi
  • Use of sulfur and selenium compounds as precursors to nanostructured materials
    Patent number: 10253256
    Abstract: The presently disclosed subject matter provides processes for preparing nanocrystals, including processes for preparing core-shell nanocrystals. The presently disclosed subject matter also provides sulfur and selenium compounds as precursors to nanostructured materials. The presently disclosed subject matter also provides nanocrystals having a particular particle size distribution.
