Patents by Inventor Leanne Julia Alarid

Leanne Julia Alarid 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).

  • Self-assembly method for core/shell nanoparticles with enhanced emission
    Patent number: 10934481
    Abstract: A core/shell nanoparticle with enhanced emission comprises a fluorescent conjugated polymer core that is encapsulated by an amphiphilic block copolymer shell. The core/shell nanoparticle structure confines the electronic charge to improve quantum yield and is water soluble to enable low-cost and environmentally friendly processing.
    Type: Grant
    Filed: May 15, 2018
    Date of Patent: March 2, 2021
    Assignees: National Technology & Engineering Solutions of Sandia, LLC, University of Akron
    Inventors: Hongyou Fan, Kaifu Bian, Leanne Julia Alarid, Yu Zhu
  • Method for the preparation of uniform triaminotrinitrobenzene microparticles
    Patent number: 10723671
    Abstract: A new, rapid and inexpensive synthesis method for monodispersed triaminotrinitrobenzene (TATB) microparticles based on micelle-confined precipitation that enables control of microscopic morphology. The morphology of the TATB microparticles can be tuned between quasi-spherical and faceted by controlling the speed of recrystallization.

  • Synthesis of energetic material particles with controlled morphology
    Patent number: 10626061
    Abstract: A surfactant-assisted self-assembly method can be used to crystallize energetic materials with controlled morphology. Microparticles of hexanitrohexaazaisowurtzitane (CL-20) formed by this method may have enhanced functional reproducibility due to their monodisperse nature, and decreased shock sensitivity due to their sub-2 ?m particle size.
