Provided is nanostructured sand, a process for producing same, a process for separating a pollutant-water mixture, and uses of the nanostructured sand.

An absorbent core composite is disclosed for incorporation into a disposable absorbent article. The composite includes a first material layer and a second material layer (preferably nonwoven) partially secured to the first material layer to define at least one pocket therebetween. Preferably, multiple pockets are defined, except in the case of where a generally uniform layer or bed of absorbent is preferred or better suited fro the application. The pocket is said have a fixed initial volume. Further, an aggregate of absorbent particles is provided in the pocket(s) to occupy a portion of the fixed initial volume. The absorbent particles are preferably SAP particles and is characterized by a dry volume associated with a dry state and a swell volume associated with a liquid saturation state. In respect to or for the pocket, the aggregate is characterized by a collective dry volume and a collective swell volume, wherein the pocket has an initial configuration that retains the aggregate therein.

A woven fabric formed of fabric fibers or threads coated with a hydrogel, wherein said hydrogel is not crosslinked or is partially crosslinked to the fabric fibers or thread, wherein the hydrogel has a number of excess reactive molecules that are available for a reaction with one or more molecules solvated in an aqueous solution, and wherein the reactive molecules of the hydrogel can reversibly bond with the molecules solvated in an aqueous solution, such that the reactive molecules of the hydrogel attract the molecules solvated in aqueous solution when the hydrogel coated fabric substrate is exposed to an aqueous solution.

The present invention provides novel chromatographic materials, e.g., for chromatographic separations, processes for its preparation and separations devices containing the chromatographic material; separations devices, chromatographic columns and kits comprising the same; and methods for the preparation thereof. The chromatographic materials of the invention are chromatographic materials comprising having a narrow particle size distribution.

The present disclosure relates to a substrate containing passive NO.sub.x adsorption (PNA) materials for treatment of gases, and washcoats for use in preparing such a substrate. Also provided are methods of preparation of the PNA materials, as well as methods of preparation of the substrate containing the PNA materials. More specifically, the present disclosure relates to a coated substrate containing PNA materials for PNA systems, useful in the treatment of exhaust gases. Also disclosed are exhaust treatment systems, and vehicles, such as diesel or gasoline vehicles, particularly light-duty diesel or gasoline vehicles, using catalytic converters and exhaust treatment systems using the coated substrates.

A process for the production of coating graphene, and other carbon allotropes, onto carbon-coated magnetic nanoparticles while maintaining high magnetic moment and adsorption properties is disclosed.

A wiping product is disclosed that is well suited for wiping up oils and greases. More particularly, the wiping product has been engineered to wipe up and absorb oils within the interior of the product. The wiper is made from a laminate containing outer layers designed to wick away and/or adsorb oily substances from a surface. The wiper also includes an elastic middle layer that is oil absorbable. In one embodiment, the outer layers are stretch bonded to the elastic middle layer so that the outer layers gather and create void spaces within the product.

An adsorbent article for CO.sub.2 capture and methods of making the same. The adsorbent article for CO.sub.2 capture includes a ceramic substrate, a plurality of inorganic support particles, and an organic CO.sub.2 sorbent on the support particles. The ceramic substrate includes a plurality of porous partitions walls that define a plurality of open channels extending from an inlet end to an outlet end of the ceramic substrate. The organic CO.sub.2 sorbent is supported by the inorganic support particles within the pores of porous partition walls of the ceramic substrate. The surfaces of the porous partition walls surfaces defining the open channels are essentially free of the organic CO.sub.2 sorbent.

A composition for absorbing liquids such as water and oil can include a thermoplastic elastomeric copolymer, a superabsorbent material, and a solvent. The composition can be applied as a coating to a non-woven substrate. A method of removing water or oil from a surface employing the composition is also disclosed.
