Patents by Inventor Xingui Li

Xingui Li 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).

  • Lead ion sensors, methods of making and uses thereof
    Patent number: 9952173
    Abstract: Copolymers including at least one optionally substituted 2-hydroxy-5-sulfonic aniline as a first constituent unit and at least one optionally substituted phenylenediamine as a second constituent unit are disclosed. Compositions containing the copolymers, and methods of making the copolymers are also disclosed. The compositions can also contain for example an ethylene-vinyl acetate copolymer (EVA) and/or electrical conducting additives. The compositions can, for example, be used for detecting lead ions in a sample.
    Type: Grant

  • Fluoranthene copolymers and methods of making and using the same
    Patent number: 8394643
    Abstract: The present application relates to copolymers having at least one optionally substituted fluoranthene as a first monomer unit and at least one optionally substituted pyrrole as a second monomer unit. The copolymer may, for example, emit green light when exposed to a blue or ultraviolet radiation. Methods of making the copolymer are also disclosed, as well as methods and apparatuses for producing light and detecting nitroaromatics using the copolymer.
