摘要： A composition for dry reagent colorimetric sensing of nanoparticles in aqueous media, including sodium borohydride (NaBH4), methylene blue (MB), and 4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid (HEPES) in the form of a powdered mixture. The composition may be formed by combining MB, HEBES, and water to yield an aqueous mixture, removing water from the aqueous mixture to yield a solid mixture, and combining NaBH4 powder with the solid mixture to yield the composition. The composition may be used to detect metallic nanoparticles an aqueous solution by combining the composition with an aqueous solution to yield a test solution, and assessing a concentration of the metallic nanoparticles in the test solution based on absorbance of light by the test solution. The composition may be provided in an assay kit for sensing nanoparticles in aqueous media.

摘要： A photoreactor including a reservoir configured to hold water, the reservoir defining an inlet and an outlet, and a multiplicity of optical fiber assemblies positioned in the reservoir. Each optical fiber assembly includes one or more optical fibers coated with a composition comprising a photoresponsive polymer and a light source optically coupled to the one or more optical fibers. The photoresponsive polymer undergoes a change from an initial state to an irradiated state when irradiated with light from the light source, and photoresponsive polymer in the irradiated state is adapted to bind an ion from the water.

摘要： Preparing a porous hybrid media includes contacting porous media (e.g., strong base ion-exchange media) with an aqueous solution including aluminum ions to yield a aluminum-ion-containing porous media, contacting the aluminum-ion containing porous media with a reducing agent to impregnate elemental aluminum in the porous media, and oxidizing the elemental aluminum to yield a porous hybrid media including aluminum hydr(oxide) impregnated in the porous media. In some cases, a pH of an aqueous mixture including the aluminum-ion-containing porous media may be adjusted to form a floc including aluminum hydroxide, and the aluminum hydroxide-containing porous media may be contacted with a reducing agent to yield a porous hybrid media including aluminum hydr(oxide) impregnated in the porous media. The porous hybrid media may advantageously be prepared at low temperature (e.g., room temperature).
