  • Patent number: 9595654
    Abstract: A thermoelectric composite includes a plurality of particles comprising a crosslinked polymer having a heat deflection temperature greater than or equal to 200° F. and a segregated network comprising a first filler material which is disposed between the particles to produce a thermoelectric response in response to application of a voltage difference or temperature difference across the thermoelectric composite. The first filler material includes a carbon material, a metal, a metal disposed on a carbon material, or a combination thereof. A process for preparing a thermoelectric article includes combining a first filler material and a plurality of particles comprising a polymer to form a composition and molding the composition to form a thermoelectric article, wherein the thermoelectric article is configured to produce a thermoelectric response in response to application of a voltage difference or temperature difference across the article.

  • Patent number: 9580658
    Abstract: A method of obtaining a hydrocarbon material from a mined material comprises forming a colloidal dispersion comprising solid particles and a carrier fluid. The colloidal dispersion is mixed with a mined, hydrocarbon-containing material to form an emulsion stabilized by the solid particles. At least one property of the emulsion is modified to destabilize the emulsion. Additional methods of obtaining a hydrocarbon material from a mined material, and a stabilized emulsion are also described.

  • Publication number: 20160348488
    Abstract: A method of extracting hydrocarbons from a subterranean formation comprises introducing a solution comprising a silicon-containing compound into the subterranean formation. The silicon-containing compound may comprise a terminal group comprising one of an alkanoate group, a fluoroalkanoate group, and a perfluoroalkanoate group, and one or more of an alkoxy group and a chlorine atom bonded to the silicon atom. The method comprises attaching the silicon-containing compound to one or more of formation surfaces of the subterranean formation to form an oleophilic surface on the one or more of the formation surfaces and the surfaces of proppant particles.

  • Publication number: 20150353836
    Abstract: A flocculant, according to embodiments of the present disclosure, includes a core nanoparticle and at least one positively charged functional group on a surface of the core nanoparticle. The nanoparticle may comprise a silica, alumina, titania, iron oxide, iron nitride, iron carbide, or a carbon-based nanoparticle. The flocculant may be used, in a method of bitumen recovery, to neutralize and agglomerate bitumen droplets and/or mineral particles derived from oil sands ore. The bitumen droplets agglomerate about the core nanoparticle of the flocculant to form bitumen flocs, while the mineral particles agglomerate about the core nanoparticle of the flocculant to form mineral flocs. The buoyant bitumen flocs may then separate from the dense mineral flocs to enable high-yield recovery of bitumen from oil sands.
