Provided are separators for use in an electrochemical cell comprising (a) an inorganic oxide and (b) an organic polymer, wherein the inorganic oxide comprises organic substituents. Also provided are electrochemical cells comprising such separators.

Hydrophobic shaped silica bodies having low density and low thermal conductivity are produced by forming a dispersion of silica in a solution of binder and organic solvent, and removing the solvent and shaping to form a shaped body. The shaped bodies retain their hydrophobicity, are stable with regards to shape, and are useful in acoustic and thermal insulation.

The present invention provides a liquid composition of quicklime particles within an alkylene glycol-based paste or slurry environment, which allows for pumpability and meterability of a liquid composition into cementitious materials such as concrete and mortar. Treated quicklime particles of the present invention manifest an unexpected and surprising hydration induction postponement behavior, as demonstrated through calorimetric testing.

A method of manufacturing a cementitious composition comprising: dispersing expanded polymeric microspheres into a liquid dispersion, optionally wherein the liquid dispersion comprises an aqueous dispersion; and incorporating the liquid dispersion comprising expanded polymeric microspheres into the cementitious composition; wherein the expanded polymeric microspheres are present in the liquid dispersion in an amount of about 0.1 to about 15 percent by weight, based on the total weight of the dispersion, prior to incorporation into the cementitious composition. An admixture for cementitious compositions comprising unexpanded polymeric microspheres and sodium hydroxide.

A liquid water-based solution for application of temporary floor markings on a polyurethane coated floor and a method of applying the same is disclosed. According to one aspect, the solution comprises an acrylic copolymer, a surfactant, and a coloring agent. The solution is dispensable through a foam applicator so that it can be used to form temporary lines for recreational and athletic activities. The solution has a drying time when applied to the polyurethane floor of under five minutes and can remain water soluble for an extended period of time so that it can be removed without damaging the underlying surface.
