Patents by Inventor Jeffery Ray Owens

Jeffery Ray Owens 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).

  • 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

  • Patent number: 10564074
    Abstract: Rose Bengal for detecting a presence of chemical warfare agents. A method of detecting presence of a chemical warfare agent and includes applying a quinoid form of Rose Bengal to a substrate. When the substrate is exposed to the chemical warfare agent, a lactone form of Rose Bengal is spectrally observed because presence of the chemical warfare agent converts the quinoid form to the lactone form of Rose Bengal.

  • Patent number: 10384090
    Abstract: A method of using select Schiff base compounds for chemical agent detoxification. The method including applying a compound to the contaminated substrate. The compound includes an imine having at least one Schiff base nitrogen and an alkyl substituent or an aryl substituent having an electron acceptor. The at least one Schiff base nitrogen is spaced away from the electron acceptor by a distance ranging from about 200 pm to about 1000 pm. The substrate and the compound are dried. The at least one Schiff base nitrogen of the compound promotes a nucleophilic attack on an electrophilic site of the toxic chemical agent.

  • 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.

  • Patent number: 9470610
    Abstract: Rose Bengal for detecting a presence of and decomposing contaminants. A method of detecting the presence of a contaminant includes treating a substrate with Rose Bengal and exposing the substrate to a light having a wavelength within the visible spectrum. A response of the Rose Bengal is monitored during the light exposure. When a contaminant is present and is exposed to the light, a conversion of the Rose Bengal between a quinoid form and a lactone form is induced.
