  • Patent number: 10714697
    Abstract: A method for making a nanostructure includes preparing a perovskite precursor in a solvent where the perovskite concentration ranges from about 0.5M to about 1.5M. A substrate is coated in the perovskite precursor, and the perovskite precursor is annealed onto the substrate, thereby forming the nanostructure including the substrate with perovskite nanocrystal deposits.
    Type: Grant

    Assignee: The United States of America as Represented by the Secretary of the Navy
    Inventors: Alfred J. Baca, John Stenger-Smith, M. Joseph Roberts
  • Patent number: 9932485
    Abstract: A film, coating, appliqué and method to eliminate paint removal via hazardous methods and maintain effective corrosion inhibition via employment of a re-useable coating. Embodiments of the invention generally relate to a multilayer film having a first layer constructed of at least one electro-active polymer, a second layer constructed of at least one flexible electrically-conductive solid, and a third layer constructed of at least one inert polymer.

    Inventors: Peter Zarras, John Stenger-Smith, William Lai
  • Publication number: 20050246888
    Abstract: A supercapacitor comprising a poly(3,4-ethylendioxythiophene) (PEDOT) and poly(3,4-propylenedioxythiophene) (PProDOT) as electrode couples for the capacitor and a pair of gel electrolyte layers disposed between the electrodes. The gel electrolytes are separated by a battery paper and are selected from a group consisting of a lithium salt and an organic electrolyte.

  • Patent number: 5520968
    Abstract: Second-order nonlinear optical polymeric films, including alternating monlecular layers of two head-to-head, mainchain, amphophilic, chromophoric polymers, one polymer having the electron donating end of the chromophore attached to hydrophilic groups, and the other polymer having the electron donating end of the chromophore attached to hydrophobic groups, and methods of fabricating the films for use in optonics.

    Inventors: Kenneth J. Wynne, Geoffrey A. Lindsay, James M. Hoover, John Stenger-Smith, Ronald A. Henry, deceased, Andrew P. Chafin
  • Patent number: 5212269
    Abstract: Processible chromophoric polymers having nonlinear optical properties and wherein the chromophore is present in and is a part of the polymer backbone, including substantially all of the monomer or repeat units, with the dipole moments pointing in the same direction (head-to-tail) along the polymer backbone. Such polymers include phenylene, phenylene vinylene, stilbenylene, phenyl piperdine, and coumarin polymers.
    Type: Grant

  • Patent number: 5210219
    Abstract: Novel conjugated stilbenylene polymers are disclosed having non-linear optical properties, and which can be converted to electrically conductive polymers. Such polymers are produced by reacting a novel bis-cycloalkylene sulfonium salt of 2,5-dimethyl stilbene, e.g. 2,5-(4'-methoxy)-stilbene dimethylene bis-(tetramethylene sulfonium bromide), with alkali metal hydroxide to form a cycloalkylene sulfonium salt precursor polymer, and then heating the precursor polymer under conditions to produce the stilbenylene vinylene polymer, e.q. poly(2,5-(4'-methoxy) stilbenylene vinylene).
    Type: Grant

  • Patent number: 5162470
    Abstract: Novel conjugated stilbenylene polymers are disclosed having non-linear optical properties, and which can be converted to electrically conductive polymers. Such polymers are produced by reacting a novel bis-cycloalkylene sulfonium salt of 2,5-dimethyl stilbene, e.g. 2,5-(4' -methoxy)-stilbene dimethylene bis-(tetramethylene sulfonium bromide), with alkali metal hydroxide to form a cycloalkylene sulfonium salt precursor polymer, and then heating the precursor polymer under conditions to produce the stilbenylene vinylene polymer, e.g. poly(2,5-(4'-methoxy)stilbenylene vinylene).
