  • Graphene films from carbon sources
    Patent number: 12077437
    Abstract: Methods and apparatuses for forming a graphene film, and graphene films produced thereby. A method of forming a graphene film includes depositing a carbon source onto a substrate within a deposition environment including a vacuum to form the graphene film on the substrate. The carbon source includes coal, a coal component, or a combination thereof.
    Type: Grant
    Filed: August 25, 2021
    Date of Patent: September 3, 2024
    Assignee: Energy and Environmental Research Center Foundation
    Inventors: Alexander Azenkeng, James Tibbetts, Jason Laumb
  • UPGRADED COAL
    Publication number: 20240269689
    Abstract: Upgraded coal, method of forming the same, and graphene films and quantum dots made therefrom. A method of upgrading coal includes cleaning coal to form a cleaned coal residue. The method also includes (A) reacting the cleaned coal residue with an oxidizable inorganic metallic agent, or (B) reacting the cleaned coal residue with a reducing agent, or a combination thereof, to form the upgraded coal.
    Type: Application
