  • Electrochemical capacitor device with a biofilm
    Patent number: 11862394
    Abstract: An electrochemical capacitor (300) for use with a biofilm is presented. The electrochemical capacitor includes a first electrode (324) coupled to a first porous layer (326), a second electrode (334) coupled to a second porous layer (336); and an electrolyte (310) provided between the first porous layer (326) and the second porous layer (336). At least one of the first porous layer (326) and the second porous layer (336) has a plurality of cavities adapted to receive redox-active metabolites produced by the biofilm. Also presented is an electrochemical capacitor device, such as a skin patch that includes a support layer attached to the electrochemical capacitor (300). Also presented is a power source that includes the electrochemical capacitor (300) and a biofilm provided between the first electrode (324) and the second electrode (334) of the electrochemical capacitor (300).

  • Process for producing graphene
    Patent number: 9440856
    Abstract: A process for producing graphene by providing a plurality of metallic particles as templates for graphene formation and providing a carbon source; reacting the metallic particles and carbon source under conditions suitable for graphene formation; and forming graphene particles on the metallic particles. The graphene particles formed on the metallic particles are of a size and shape substantially corresponding to the size and shape of the metallic particles.
