Patents by Inventor James A. Kenar

James A. Kenar 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).

  • Carbonated estolides and methods of making and using the same
    Patent number: 9850222
    Abstract: Disclosed herein are the conversion of estolide compounds having unsaturated fatty acid groups into estolides containing cyclic carbonate moieties and methods of making and using the same. The estolides containing a cyclic carbonate may be used to produce urethane containing estolides.
    Type: Grant
    Filed: August 1, 2016
    Date of Patent: December 26, 2017
    Assignee: The United States of America, as represented by the Secretary of Agriculture
    Inventors: Kenneth M. Doll, Terry Isbell, Steven C. Cermak, James A. Kenar

  • Carbonate phase change materials
    Patent number: 8679365
    Abstract: Phase change materials that include oleochemical carbonates absorb and release latent heat upon changing phases from solid to liquid (melting) or from liquid to solid (solidifying). The oleochemical carbonates are prepared from oleochemical alcohols derived from animal fats and vegetable oils or other bio-based substances. These oleochemical carbonates have melting temperatures with a relatively high heat of fusion and are non-corrosive. Oleochemical carbonates can be mixed together in various proportions to adjust melting/solidification temperature ranges as required by a particular application.
    Type: Grant

  • Aqueous starch-oil dispersions having improved UV stability and absorbing ability
    Patent number: 7875262
    Abstract: A delivery system for UV-protective sunscreen agents, antioxidants, skin care agents, cosmetics and the like comprising feruloylated acylglycerols (FAG) and other cinnamate-modified vegetable oils (CMVO) incorporates the agents into starch-based composites. These composites permit the use of a lower level of CMVO for comparable UV protection than if the CMVO were used alone.
