Abstract: A single-layer GNPs/graphene includes a carrier layer as a substrate; a graphene layer on the carrier layer; and a plurality of gold nanoparticles (GNPs) evenly distributed on the graphene layer, which formed as a GNP layer; and wherein the graphene layer and the GNP layer has the effect of UV absorption; and longitudinal sizes of the GNP layers will affect the absorbing wavelengths. For forming multi-layer GNPs/graphene, the above second and third steps can be repeated until the number of the GNP layer and graphene layer has achieved to a predetermined one. Moreover, the methods for forming above structures are provided in the present invention.

Abstract: A solid state energy storage device has two electrodes, a membrane separator and a solid electrolyte having a substantially solid solvent, a salt and a mediator. The energy storage device stores electric charge by both Faradaic and non-Faradaic systems. The energy storage device may include activated carbon mixed with the electrolyte and sonicated to provide connection between the activated carbon and the mediator. The energy storage device is hot pressed to increase conductivity. The two electrodes may be asymmetric in amount of reduced and oxidized species of mediator.
