    摘要: The present invention relates to a latex comprising water and a layered material intercalated with a polymer. The invention also relates to a nanocomposite material comprising a layered material intercalated with a polymer. The latex can be produced by forming a dispersion of layered material in water, adding surfactant, polymerizable monomer or monomers, and a polymerization initiator to the mixture and then polymerizing the monomer to form a latex. The latex can also be formed from preformed polymers. Composite materials formed from latexes produced by either method have improved mechanical properties and reduced air permeability.

    摘要: Shunt currents can be eliminated in electrochemical devices by introducing nulling currents via auxilary electrodes. In electrochemical devices including those having a circulating electrolyte, such electrodes are designed to have a generally annular shape in order to provide a substantially uniform current density profile along a common electrolyte carrying manifold. The uniform current density profile allows for the elimination of these harmful shunt currents with a minimum of power consumption.

    摘要: A method for enhancing the stability of a water-in-oil emulsion pretreating at least a portion of the oil prior to emulsification. The pretreatment step may consist of adding polymers to the oil, biotreating the oil, photochemically treating the oil, or combinations thereof. The emulsion may be used in various enhanced oil recovery methods including using the emulsion as a flooding agent to displace hydrocarbons in a subterranean formation, and using the emulsion as a barrier fluid for diverting flow of fluids in the formation.
