Embodiments relate to preparation of expandable particulates and their use in fracturing operations. An embodiment provides a method for treating a subterranean formation comprising: introducing a treatment fluid comprising expandable particulates into the subterranean formation, wherein the expandable particulates each comprise a particulate substrate, a swellable material coating the particulate substrate, and an exterior coating comprising a resin; and depositing at least a portion of the expandable particulates in the subterranean formation.

Disclosed are methods for incorporating core materials such as phase change materials or admixtures into building materials like concrete. The methods use cenospheres, which are then etched and loaded with the core material. The composition can also be coated with a thin film. Compositions containing cenospheres loaded with the various core materials are disclosed, as are building materials containing such compositions.

Some embodiments of the present disclosure relate to a roofing material, wherein the roofing material may comprise a plurality of coated roofing granules, wherein each of the plurality of the coated roofing granules may comprise a roofing granule having an outer surface; and a granule coating, wherein the granule coating is disposed on at least a portion of the outer surface of the roofing granule, and wherein the granule coating comprises graphene. Some embodiments of the present disclosure relate to a roofing material, wherein the roofing material may further comprise a reflective base coating, wherein the reflective base coating is positioned between the outer surface of the roofing granule and the granule coating.

A method of coating a surface of a concrete structure in situ, which comprises the step of applying to the surface of the concrete of the concrete structure a liquidous coating of a modified polyvinylidene fluoride (PVDF) or polyvinylidene difluoride (PVDF) material in an air dryable solution comprising: a PVDF or a PVDF co-polymer or a combination of PVDF and PVDF copolymer to form a blend with a compatible acrylic and/or other compatible polymer that is fluorinated to between about 30% to about 75% by weight excluding any solvent; the PVDF or PVDF co-polymer or blend thereof having at least about 45% PVDF molecular structure by weight when dried; the PVDF or PVDF co-polymer having a polymer crystallinity of at least about 30% by weight; and a solvent.

Granulate material for a radical chain-growth polymerization based coating formulation, adapted to minimize inhibition of resin polymerization by ambient air, composition of granulate material, coating formulation kit, and process for applying a radical chain-growth polymerization based coating formulation kit.

Article made of conglomerate material in the form of a slab including an aggregate which includes granules of expanded material having a selected particle size range and defining between them inter-granular cavities containing only air and no filling material. The aggregate also includes a binder present in a controlled minimum quantity sufficient for lining the granules of expanded material. The article also includes a lining layer integral with the aggregate. Also, a method for the production of an article made of conglomerate material.
