Abstract: Nanoscale additives and methodology for their use during polymer-aided sludge dewatering to increase the dewatering efficiency compared to traditionally used polymer-only dewatering processes. The nanoscale additive increases the percent solids in the dewatered cake compared to polymer-only treatment. When the nanoscale additives are added, the centrifugal force (shear) required to obtain high percent solids can be significantly reduced and the optimum polymer dose required for effective dewatering is also significantly reduced.

Abstract: A new class of carbon-based sorbents for vapor-phase mercury removal is disclosed in this invention. The optimum structure of the sorbent particles, and a method to produce the sorbent, are described. The sorbent is based on carbon particles with a metal-oxide coating on the surface. The thin metal-oxide layer acts as a barrier for the adsorption of Air Entrainment Admixture (AEA), the component used to stabilize bubbles in cement), thereby enhancing its concrete friendliness. The metal-oxide is coated on the surface of carbon, using a solution-based method. The metal-oxide coated carbon was further modified with sulfur molecules, to increase its mercury removal capacity.
Abstract: A silicone based coating for fabrics utilizing dual nanocomposite fillers providing enhanced mechanical and thermal properties to the silicone base. The first filler includes nanoclusters of polydimethylsiloxane (PDMS) and a metal oxide and a second filler of exfoliated clay nanoparticles. The coating is particularly suitable for inflatable fabrics used in several space, military, and consumer applications, including airbags, parachutes, rafts, boat sails, and inflatable shelters.

Abstract: A low cost and scalable processes for producing nanostructured LiFexM1-xPO4 and nanostructured LiFexM1-xPO4/C composite powders, where 1?x?0.1 and M is a metal cation, such as Mn, Co, Ni, and V. Electronics made of either nanostructured LiFexM1-xPO4 powders or nanostructured LiFexM1-xPO4/C composite powders exhibit good electrochemical properties. The electronic conductivity of nanostructured LiFexM1-xPO4 powders is enhanced by intimately mixing them with ultrafine carbon particles. Thus, the use of nanostructured LiFexM1-xPO4/C composite powders will lead to high power density, low cost and environmentally friendly rechargeable Li-ion batteries.
