  • Controlled microwave assisted synthesis of functionalized silica nanoparticles
    Patent number: 10919777
    Abstract: A functionalized fiber. The functionalized fiber includes a fiber strand and silica nanoparticles at least partially encapsulating the fiber strand. The silica nanoparticles are synthesized by hydrolyzing a tetramethyl orthosilicate in hydrochloric acid to form silicic acid monomers. The silicic acid monomers are diluted in acetone and irradiated for a time that is less than 90 seconds with an energy source configured to generate microwave frequency energy to polymerize the silicic acid monomers into the silica nanoparticles.
    Type: Grant
    Filed: May 16, 2018
    Date of Patent: February 16, 2021
    Assignee: United States of America as represented by the Secretary of the Air Force
    Inventors: Jeffery Ray Owens, Derek Lovingood
  • Cementitious material
    Patent number: 10800703
    Abstract: A rapid-setting composition includes fly ash and an activator solution for mixing with the fly ash. The activator solution has a silicate solution including a monovalent hydroxide. The activator solution when mixed with the fly ash produces a composition that has a final set time of no more than about 65 minutes.

  • Controlled microwave assisted synthesis of functionalized silica nanoparticles
    Patent number: 10000390
    Abstract: A method of synthesizing silica nanoparticles. The method includes hydrolyzing a silica precursor to form a plurality of monomers, each monomer of the plurality comprising a microwave reactive silicon species. The plurality of monomers is irradiated by an energy source configured to generate microwave frequency energy. Irradiation cases the plurality of monomers polymerize into a silica nanoparticle.
