The process includes the steps of solvent extraction of volatile materials from high volatile material green coke powder. When a desirable amount of the volatile materials have been extracted, the solvent strength is altered to cause some of the volatile materials to precipitate on the powder particles to coat the same. The coated and solvent-extracted particles are then separated from the solvent and oxidatively stabilized, then carbonized and preferably graphitized. The volatile materials remaining in the solvent are valuable and are recovered for use in other processes and other products.

  • Publication number: 20100099011
    Abstract: A method and device for operating a fuel cell system. The method includes applying a catalyst ink or related liquid that contains an electrocatalyst and electrolyte to a diffusion media so that the portion of the media that includes the electrocatalyst can function as a fuel cell electrode, specifically an anode or cathode. In addition to the electrocatalyst and electrolyte, the ink contains a solvent and a co-solvent, where the co-solvent has a boiling point that exceeds that of the solvent. Heating or related processing removes the solvent from the diffusion layer, but leaves at least some of the co-solvent in liquid form. This residual liquid reduces the likelihood of electrode cracking that may otherwise form during subsequent electrode processing.

  • Publication number: 20100097742
    Abstract: High-surface-area carbon nanostructures coated with a smooth and conformal submonolayer-to-multilayer thin metal films and their method of manufacture are described. The preferred manufacturing process involves the initial oxidation of the carbon nanostructures followed by a surface preparation process involving immersion in a solution with the desired pH to create negative surface dipoles. The nanostructures are subsequently immersed in an alkaline solution containing a suitable quantity of non-noble metal ions which adsorb at surface reaction sites. The metal ions are then reduced via chemical or electrical means. The nanostructures are exposed to a solution containing a salt of one or more noble metals which replace adsorbed non-noble surface metal atoms by galvanic displacement. The process can be controlled and repeated to obtain a desired film coverage.

  • Publication number: 20100086787
    Abstract: Exemplary embodiments provide coating compositions having pseudo-fluorine surface and methods for processing and using the coating compositions. The coating composition can include, for example, a plurality of fluorine-containing resin fillers and a plurality of nanotubes (e.g., carbon nanotubes (CNTs)) dispersed in a polymer matrix that contains, e.g., one or more cross-linked polymers. The fluorine-containing resin fillers can provide a pseudo-fluorine surface for a low surface energy of the coating composition. The nanotubes can be dispersed in the polymer matrix to provide an improved mechanical robustness of the coating composition. The coating composition can be coated on a member surface, wherein the coated member can be, for example, a fuser member, a fixing member, a pressure roller, or a release agent donor member, used in an electrostatographic printing device or process.
