  • MULTIFERROIC NANOSCALE THIN FILM MATERIALS, METHOD OF ITS FACILE SYNTHESES AND MAGNETOELECTRIC COUPLING AT ROOM TEMPERATURE
    Publication number: 20160012951
    Abstract: Methods of producing a multiferroic thin film material. The method includes the steps of providing a multiferroic precursor solution, subjecting the precursor solution to spin casting to produce a spin cast film, and heating the spin cast film. The precursor solution may include Bi(NO3)3.5H2O and Fe(NO3)3.9H2O in ethylene glycol to produce a bismuth ferrite film. Further, the thin film may be utilized in varied technological areas, including memory devices for information storage.

  • Self-Cleaning Coating for Protection Against Hazardous Biopathogens and Toxic Chemical Agents Utilizing Both Super Hydrophobic Effects and Suitable Oxide Interfaces
    Publication number: 20110220855
    Abstract: A dual action self-cleaning and self-decontaminating coating consisting of a superhydrophobic aspect capable of cleaning the surface by having water droplets moving along the surface remove contaminants and a photochemically active aspect capable of disinfecting the surface by producing hydroxyl radicals in the presence of UV radiation and moisture.

  • Method for producing a self decontaminating surface
    Patent number: 6235351
    Abstract: A method for producing a self decontaminating surface to decontaminate chemical and biological contaminants that are deposited on the surface and decontaminatable through reaction with free hydroxyl radicals. The method first includes determination of a surface to be treated and which is exposable to ultraviolet light. Second, a coating of nanoparticles of a transition metal oxide, non-limitedly exemplified by anatase titanium dioxide, is applied to the chosen surface. Application of the coating is accomplished by spraying heated nanoparticles or clusters thereof from a feed stock onto the surface to form a nanoparticle coating, with the nanoparticles being at a temperature of at least about 750° C. upon exit from a spray apparatus and of a size between about 5 nm and 100 nm.
