  • Patent number: 10577279
    Abstract: A method of modifying glass frit involves treating the frit with a grain-boundary-healing compound. The method increases transmission and clarity, and reduces haze of a fired enamel coating made from such modified glass frit as compared to a coating not made from such modified glass frit. The grain-boundary-healing compound influences the chemistry at the grain boundaries to prevent haze. The compound burns out to yield a fluxing material that dissolves alkaline carbonates or bicarbonates on the surface of the glass frit. The dissolved species are incorporated into the enamel coating, thereby promoting the fusion of the glass frit and reducing the amount of haze in the enamel coating. The additives also function to prevent the formation of seed crystals on the surface of the glass frit that may inhibit the fusion of the glass frit.

  • Patent number: 9671529
    Abstract: The present subject matter provides a transitional layer and related methods, used to increase the transmission or reflection of light between two mediums having different indices of refraction. The transitional layer is disposed between the two mediums and the transmission or reflection of light is increased by the interaction of light with the transitional layer. The transitional layer has light scattering particles dispersed therein, a single-layer gradient index-of-refraction, a multi-layer gradient index-of-refraction, alternating layers of high and low index-of-refraction, or a combination thereof, in order to increase the transmission or reflectance of light between the two mediums.

  • Patent number: 7527832
    Abstract: A plasma spray process for structuring self-cleaning glass surfaces and self-cleaning glass surfaces formed according to the process. Molten or heat softened particles of inorganic material are plasma spray deposited onto the surface of a substrate to create a micro-rough surface. If desired, a hydrophobic top coating layer can optionally be applied to the micro-rough surface. The micro-structured surface formed according to the invention is durable and self-cleaning.

  • Patent number: 7524531
    Abstract: The present invention involves growing diatoms on a surface for the purpose of forming nanoscale-sized siliceous structures on the surface. In accordance with the invention, diatom films are grown on various substrates, which are then fired to remove all organic material from the diatoms and produce a surface coated with intricate, nanoscale-sized structures. The nanoscale-sized structured surface is subsequently treated with a hydrophobic film-forming agent to form a structured self-cleaning surface.
