  • Frost free surfaces and method for manufacturing the same
    Patent number: 9371595
    Abstract: Frost-free surfaces and methods for manufacturing such surfaces are described. The frost-free surfaces reduce ice build-up, prevent vapor condensation and reduce adhesion force between ice and a solid substrate. The surfaces can be on parts used in devices where superhydrophobic properties may be obtained post or during device manufacturing. The superhydrophobic properties are the result of aluminum oxide clusters made on such surfaces.
    Type: Grant
    Filed: November 10, 2009
    Date of Patent: June 21, 2016
    Assignee: Conopco, Inc.
    Inventor: Chunbo Ran
  • EDIBLE COATING AND COATED FOOD PRODUCT
    Publication number: 20150110927
    Abstract: Disclosed is an edible coating, a food product coated with the coating and the method for manufacturing the food product. The coating comprises a first layer comprising first edible oil and a second layer comprising a hydrophobic edible particle wherein the hydrophobic edible particle has a diameter from 20 nm to 500 microns. The food product having the coating is resistant to becoming soggy.
