Active material compositions comprising high surface area carbonaceous materials

Abstract: Disclosed herein are negative active material compositions, comprising: a carbonaceous material (6') having a surface area of at least 250 m2/g; and an organic molecule expander (4'), wherein the ratio of carbonaceous material to expander ranges from 5:1 to 1:1, and wherein the composition has a median pore size ranging from 0.8 μιη to 4 μm. Also disclosed are electrodes and batteries comprising such compositions, and methods of making thereof.

Magnetic Field Induced Morphological Transitions in Block Copolymer/Superparamagnetic Nanoparticle Composites

Abstract: This two-dimensional computational study investigates the effect of external magnetic fields on thin film nanocomposites comprised of superparamagnetic nanoparticles dispersed within block copolymer melts, which display a variety of morphological transitions based on the field orientation, nanoparticle loading, and selectivity of the nanoparticles for the blocks. In-plane magnetic fields lead to chaining of the nanoparticles; when selective for the minority block in a hexagonal block copolymer nanostructure, this chaining results in the formation of stripe phases oriented parallel to the magnetic field. When selective for the majority block of the hexagonal structure, nanoparticle chains of sufficient persistence length drive the orientation of the hexagonal morphology with the ⟨100⟩ direction oriented parallel to the magnetic field. Out-of-plane magnetic fields induce repulsive dipolar interactions between the nanoparticles that annihilate the defects in the hexagonal morphology of the block copolymer wh...

Abstract: There are provided improved asphalt cements and bituminous paving compositions containing certain reinforcing filler compositions which impart desirable properties thereto. The filler compositions of the invention comprises certain carbon blacks which have been treated with certain non-volatile petroleum oils.

Porous carbon monoliths templated by pickering emulsions

Abstract: Porous carbon monoliths are prepared using emulsions stabilized by carbonaceous particles or aggregates. An illustrative porous carbon monolith comprises carbon black, including any graphitized carbon black particles, carbonized binder and porosity. The porosity includes first pores having a pore size within the range of from about 0.5 μm to about 100 μm and second pores having a pore size within the range of from about 1 nm to about 100 nm. The pore size distribution of the first pores does not overlap with a pore size distribution of the second pores.

Method of coating iron,nickel or cobalt alloy with aluminum

Abstract: ALLOY IN A NON-OXIDIZING ATOMOSPHERE TOA TEMPERATURE ABOVE ABOUT 1800*F. TO CAUSE THE ALUMINUM-MAGNESIUM MATERIAL TO COAT AND DIFFUSE INTO THE TREATED SURFACE OF THE IRON, NICKEL OR COBALT BASE ALLOY. A PROCESS FOR COATING AN IRON, NICKEL OR COBALT BASE ALLOY IS PROVIDED WHICH COMPRISES TREATING A SURFACE OF THE SELECTED ALLOY WITH A MATEIAL CONSISTING ESSENTIALLY OF FROM ABOUT 10 TO 30 WEIGHT PERCENT MAGNESIUM WITH THE BALANCE BEING ALUMINUM AND THEN HEATING THE SO-TREATED
