Abstract: Disclosed herein are particulate sorbents, such as sorbents that can be used for mercury removal applications. The absorbent can comprise at least one ammonium phosphate and at least one activated carbon selected from unhalogenated activated carbon and halogenated activated carbon, wherein the halogenated activated carbon contains at least one halogen impregnant on its surface. Also disclosed are methods of making sorbents, and methods of mercury removal, e.g., from flue gas generated by coal combustion.

Abstract: Disclosed herein are cathode formulations comprising a lithium ion-based electroactive material having a D50 ranging from 1 ?m to 6 ?m; and carbon black having BET surface area ranging from 130 to 700 m2/g and an OAN ranging from 150 mL/100 g to 300 mL/100 g. Also disclosed are cathode formulations comprising a first lithium ion-based electroactive material having a particle size distribution of 1 ?m?D50?5 ?m, and a second lithium ion-based electroactive material having a particle size distribution of 5 ?m<D50?15 ?m. Cathodes comprising these active materials can exhibit a maximum pulse power in W/kg and W/L of the mixture higher than maximum pulse power of the first or second electroactive material individually, or an energy density in Wh/kg and Wh/L of the mixture higher than energy density of the first or second electroactive material individually. The cathode formulations can further comprise carbon black having BET surface area ranging from 130 to 700 m2/g.

Abstract: A catalyst composition comprises a particulate support and catalyst nanoparticles on the particulate support. The catalyst nanoparticles comprise an alloy of platinum and palladium in an atomic ratio of from about 25:75 to about 75:25 and are present in a concentration of between about 3 and about 10 wt % weight percent of the catalyst composition. The catalyst composition has an X-ray diffraction pattern that is substantially free of the (311) diffraction peak assignable to PtxPd1-x, where 0.25?x?0.75.

Abstract: The present invention provides a cerium oxide particulate composition and a process for preparing a cerium oxide particulate composition comprising aggregates of approximately spherical primary particles of cerium oxide. The method involves preparing a solution of a cerium oxide precursor, aerosolizing the cerium oxide precursor solution, and heating the aerosol to provide the cerium oxide particle composition.
