Abstract: Cement compositions including ordinary Portland cement, a secondary cementitious material (SCM) including one or more of pozzolan, metakaolin, limestone, or gypsum in an amount of up to approximately 70% of a replacement level of ordinary Portland cement, and between approximately 0.05% by weight of cement (bwoc) and 2% bwoc of aggregates of mesoporous carbon nanoparticles (3DG) carbons. The cement compositions regulate nucleation and time-lapsed growth of calcium silica hydrates during initial hydration. The 3DG carbons include aggregates of mesoporous carbon nanoparticles, which include one or more interconnected bundles of electrically conductive graphene layers. The 3DG carbons include oxygen containing functional groups disposed on one or more of the surfaces of the 3DG carbons or within the 3DG carbons.

Abstract: The present invention is directed to a sealing layer that comprises a combination of polyurethane and poly(vinyl alcohol), the poly(vinyl alcohol) containing an acetoacetate functional group in its molecular structure. The sealing layer is formed from an aqueous sealing composition and shows water resistance and good barrier properties to non-polar fluids. The sealing layer can be used to seal microcells of electro-optic displays.

Abstract: Embodiments of the present disclosure describe a negative photochromatic material. Embodiments of the present disclosure further describe a method of tuning a negative photochromatic material comprising selecting an amine donor group, selecting an acceptor group, and contacting at least the selected amine donor group and the selected acceptor group to form a negative photochromatic material, wherein one or more of the selected amine donor group and the selected acceptor group tune at least an absorption range of the negative photochromatic material.
