Reduced graphite oxide in supercapacitor electrodes.
The current energy needs have put the focus on highly efficient energy storage systems such as supercapacitors. At present, much attention focuses on graphene-like materials as promising supercapacitor electrodes. Here we show that reduced graphite oxide offers a very interesting potential. Materials obtained by oxidation of natural graphite and subsequent sonication and reduction by hydrazine ...
متن کاملCharacterization of Porous Graphite Air Bearings
Byron R. Knapp, Brian P. O’Connor, Eric R. Marsh Machine Dynamics Research Lab The Pennsylvania State University, University Park, PA Introduction As the demand for higher precision machine tools and inspection equipment grows, there is a need for more precise bearing systems. The error motions of bearings with mechanical contact are dominated by the geometric and surface finish errors of their...
متن کاملPhase transition in porous electrodes.
It is shown by Monte Carlo simulation that electrochemical thermodynamics of electrolytes in a porous electrode is qualitatively different from that in the bulk with a planar electrode. In particular, first order phase transitions occur in porous electrodes when the pore size is comparable to the ion size of the electrolytes: as the voltage is increased from zero, the surface charge density and...
متن کاملLithographically defined porous carbon electrodes.
The special nature of the C C bond can lead to various polymorphic forms of carbon such as graphite, glassy-carbon, fullerenes (such as buckyballs), carbon nanotubes, and diamond. Electrodes made from carbon exhibit many useful properties including wide potential windows, low background capacitance, resistance to fouling, and catalytic activity for manyanalytes compared to solidmetal electrodes...
متن کاملA Comparative Study of Lead Oxide Modified Graphite Paste Electrodes and Solid Graphite Electrodes with Mechanically Immobilized Lead Oxides
The cyclic voltammetry of red PbO, -PbO2, -PbO2 and BaPbO3 was studied with two different types of electrodes in acidic and alkaline media. In one case, microcrystalline particles of lead oxides were mechanically immobilized on the surface of paraffin-impregnated graphite rod electrodes (PIGE), while in the other case, lead oxides were added to a paste of graphite and silicone oil. The overall ...
