Patents by Inventor Harjyoti Kalita

Harjyoti Kalita 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).

  • Plant oil-based materials
    Patent number: 9834626
    Abstract: Plant oil-based compounds are provided which possess both low viscosity and high reactive functionality. These compounds are useful in coating and composite applications, as well as related methods. Exemplary compounds can be produced by transesterification of a plant oil triglyceride with a nucleophile reactant, such as a vinyl-functional alcohol, to yield reactive fatty acid-containing monomers.
    Type: Grant
    Filed: January 13, 2014
    Date of Patent: December 5, 2017
    Assignee: NDSU RESEARCH FOUNDATION
    Inventors: Bret Ja Chisholm, Harjyoti Kalita, Samim Alam, Andrey Chernykh
  • Functionalized amphiphilic plant-based polymers
    Patent number: 9631040
    Abstract: Amphiphilic copolymers formed from plant oil-derived vinyl ether monomers and polyethylene glycol alkyl vinyl ethers are provided. Nanoparticles coated with these amphiphilic polymers are well-suited for water remediation applications.
    Type: Grant

  • MONOMERS AND POLYMERS DERIVED FROM NATURAL PHENOLS
    Publication number: 20160023980
    Abstract: Monomers, polymers and copolymers are provided that incorporate at least one naturally occurring phenolic compound, such as a plant phenol, as well as methods for producing the monomers and polymers. Plant phenols possessing a reactive group in addition to the phenolic group, such as a double bond, aldehyde, ester, alcohol or carboxylic acid, are particularly useful. Plant phenols can be isolated from a plant material, or chemically or enzymatically synthesized.
