Yong Zhong 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).

  • Patent number: 6319551
    Abstract: This invention is directed to novel silica compositions, metal silicates, germanosilicates, and metal germanosilicates, and patterned objects and films comprising the same. It also includes methods and compositions for making these films and patterned objects on substrates, ranging from silicon wafers to optical fibers, silica, sapphire, quartz and borosilicate glass. These methods incorporate the use of certain precursor compositions, procedures for their application to a substrate and subsequent treatment to produce a patterned object and/or the conversion to glass structures.
    Type: Grant

  • Patent number: 6294217
    Abstract: This invention relates to novel vitreous microlenses and optical filters and methods for their formation. This includes formation of inorganic oxide microlenses and optical filters on other objects, including the production of oxide glasses in various shapes. For example, the present invention is directed to the use of precursor materials such as carboxylated polysiloxanes, including carboxylated polygermanosiloxanes in the hydrogen or fully or partially metal ion exchanged forms to produce the vitreous microlenses and optical filters of the invention.

  • Patent number: 6248852
    Abstract: The present invention is directed to a method of forming germanium-containing silicones in which germanium is incorporated into the siloxane backbone with Ge—O—Si bond or onto a carboxylated siloxane in a form such as the germanium ester form, which has a COOGe bond. The germanium mole content ranges from 1 mol % to 50 mol %. The groups attached to silicon and/or germanium include alkyl, alkenyl, and carboxyalkyl and their derivatives. In the materials with pendant carboxylic acid groups, the protons can be replaced by metal ions such as an alkali, alkaline earth, transition metal, or rare earth metal ions. The materials can be crossinked, with the crosslinking being initiated by ultraviolet light or other means with or without a photoinitiator.
