Carbon black supercapacitors that employ thin (∼1 μm) electrodes were produced by coating and inkjet printing on a conventional current collector or directly on a separator membrane. The simplicity and diversity of ultrathin electrode fabrication were facilitated by the physical form of carbon black, which can be described as a fine particle of around 100 nm in size. It was established that the performance of carbon black in thin supercapacitor electrodes may be compared with carbon nanotube and graphene materials in those instances where fast frequency response is desired from the supercapacitor. At the same time, the fast response supercapacitors that employ nanotubes and graphenes have presently involved more elaborate fabrication routes. RC time constant of 354 μs and phase angle of -75° at 120 Hz is demonstrated for carbon black supercapacitors that employ SC3 carbon black of 1800 m 2 g -1 surface area. © 2011 Elsevier B.V.

A wet mix elastomer composite comprising carbon black dispersed in an elastomer including a blend of a natural rubber and styrene-butadiene rubber. When the wet mix elastomer composite is processed with CTV Method 1, the vulcanized wet mix elastomer composite exhibits a resistivity that A) has a natural logarithm satisfying the equation ln(resistivity)0.1(loading)+x, where x is 14, or B) is at least 2.9 times greater than the resistivity of a vulcanized dry mix elastomer composite having the same composition and prepared using Comparative CTV Method 1.

A method of removing siloxanes from a gas stream includes flowing the gas stream that carries siloxanes through an adsorbent media to remove at least part of the siloxanes from the gas stream, wherein the adsorbent media comprises lignite-based activated carbon. A spent adsorbent media is provided that contains the lignite-based activated carbon through which a gas stream containing siloxanes has been at least partially purified, and which may be regenerated.

The invention is directed to high surface area graphitized carbon and to processes for making high surface area graphitized carbon. The process includes steps of graphitizing and increasing the surface area of (in either order) a starting carbon material to form high surface area graphitized carbon. The step of increasing the surface area optionally comprises an oxidizing step (e.g., through steam etching) or template removal from composite particles. The invention is also directed to catalyst particles and electrodes employing catalyst particles that are formed from the high surface area graphitized carbon.
