    Abstract: Syntactic foams are materials including hollow microspheres distributed throughout a cured polymeric resin. Hollow microspheres within syntactic foams, including collapsible shells that enclose empty cavities, can serve as receptacles to capture environmental constituents upon applied temperature and pressure. An epoxy formulation including of EPON™ 828, HELOXY™ 61, and TETA was combined with hollow glass microspheres with isostatic crush strengths of 300, 3000, and 10,000 psi. Effects of pressure and temperature on the mechanical properties were evaluated via dynamic mechanical analysis. Storage modulus and glass transition temperature depended on formulation. Upon exposure to specific temperature and pressures, the hollow glass spheres embedded within the resin lose mechanical integrity and collapse, resulting in the generation of unencapsulated void spaces, primed to capture embedded liquid. Controllable loss of mechanical integrity enables syntactic foams to serve as on-demand receptacles to retain constituents in the surrounding environment, resulting from externally triggered pressures and temperatures.

    Abstract: A method, comprising i) contacting an aqueous solution of an organic ligand salt of the formula Ax(L-x) with a mesoporous material (MPM) to form an impregnated mesoporous salt material of the formula Ax(L-x)/MPM, ii) treating the impregnated mesoporous salt material with an aqueous acidic solution to form an impregnated mesoporous acid material of the formula Hx(L- x)/MPM, iii) contacting an aqueous solution of a metal precursor of the formula M+y(B)y with the impregnated mesoporous acid material to form an impregnated mesoporous metal organic framework precursor of the formula [M+y(B)y][Hx(L-x)]/MPM, and iv) at least one of 1) heating the impregnated mesoporous metal organic framework precursor in the absence of a solvent or 2) exposing the impregnated mesoporous metal organic framework precursor to a volatile vapor in the absence of a solvent such that the heating or the exposing forms a hybrid material of the formula (M+yL-x)/MPM, wherein the hybrid material comprises a nano-crystalline metal organic framework (MOF) embedded within the mesoporous material.

    Abstract: The disclosure provides methods and systems for decreasing nitrosamine content, e.g., in the context of non-aqueous solvent systems. It includes a method including receiving a non-aqueous solvent system and contacting the non-aqueous solvent system with a composition including one or more alkoxides to give a treated solvent system having a nitrosamine content that is lower than the starting nitrosamine content. Similarly, it includes a system including a first unit configured to remove undesirable components from a gas stream; a second unit holding a composition including one or more alkoxides, and a conduit to connect these units.
