  • HYDROGEN ISOTOPE SEPARATION SYSTEMS
    Publication number: 20230017076
    Abstract: Methods and systems for the separation of hydrogen isotopes from one another are described. Methods include utilization of a hydrogen isotope selective separation membrane that includes a hydrogen isotope selective layer (e.g., graphene) and a hydrogen ion conductive supporting layer. An electronic driving force encourages passage of isotopes selectively across the membrane at an elevated separation temperature to enrich the product in a selected hydrogen isotope.
    Type: Application
    Filed: July 29, 2022
    Publication date: January 19, 2023

  • Method of manufacturing graphene using photoreduction
    Patent number: 10941041
    Abstract: The present disclosure is directed to a low temperature method of preparing graphene. The method comprises applying a graphene oxide to a substrate and treating the graphene oxide on the substrate using photoreduction to reduce and stitch the graphene oxide to graphene. The present disclosure is also directed to graphene produced according to the aforementioned method.

  • Method of manufacturing a three-dimensional carbon structure
    Patent number: 10752986
    Abstract: The present invention is directed to a method of manufacturing a three-dimensional carbon structure. The method requires graphene layers and/or graphene oxide layers. The layers can be provided such that they correspond to the cross-section of a pre-defined shape. In this regard, the method of the present invention can be employed to manufacture a three-dimensional carbon structure having a custom shape.
