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.

Hydrogen isotope separation methods and systems

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 graphene using photoreduction

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.
