  • Cutin-like materials with advanced functionalities and methods of manufacture
    Patent number: 10934453
    Abstract: Cutin-based devices, coatings and methods of producing such devices and coatings are presented herein. Cutin-like materials (CLMs) are presented which mimic and adapt coatings found in nature for the next generation of functional coatings. Cutin has several advantages including excellent UV resistance, natural resistance to bacteria and viruses, noncorrosive, and stability under abrupt changes in temperature and environment. CLMs can be engineered at the nanoscale and readily impregnated with metals and metal oxides materials.
    Type: Grant

  • COMPOSITIONS AND METHODS TO REMOVE AMMONIA IN FRESHWATER AND SALTWATER FISH STORAGE SYSTEMS
    Publication number: 20210029977
    Abstract: Compositions, systems and methods of removing ammonia from fish storage systems are presented. A chemical water conditioner comprised of sodium formaldehyde bisulfite, cornstarch, dye and alcohol was found to have a high ammonia removal efficiency in seawater. A combination of this chemical water conditioner with modified chabazite and phosphate buffer exhibited high ammonia removal efficiency in both seawater and freshwater.

  • ADVANCED THIN PROTECTIVE FILMS
    Publication number: 20190309258
    Abstract: Thin film coatings and methods of manufacture thereof are presented. Ultra-thin coatings of cross-linked high-methoxyl pectin polysaccharides were fabricated by spin-casting solutions of citrus pectin followed by cross-linking upon exposure to solutions of calcium chloride (CaCl2) in ethanol. By adjusting temperature, degree of cross-linking, and pH of the surroundings, the pectin coatings can be carefully tuned for a desired response.
