A water filtration media which prevents or resists the accumulation of microbes while simultaneously addressing the added problem of leaching caused by the treatment of activated carbon. In one preferred embodiment, the combination of Cu and Ag on activated carbon is prepared. Steps are taken to bind the silver and copper using anionic surfactant so that there is less leaching of silver and copper from the media. In a separate embodiment, the combination of Cu and Zn is prepared, which is subjected to high temperature for better binding of the metal oxides with the carbon.

A composite filter aid may include at least one mineral associated with an antimicrobial metal compound, wherein the filter aid has a permeability ranging from 0.1 to 20 darcys. The antimicrobial metal compound can be chemically deposited on the mineral surface or bonded to mineral structure by binder or high temperature calcination.

The present disclosure described compositions which may be effective in removing contaminants from a gas stream such as nitrous oxides. The composition may include a sorbent which contains triethylenediamine and a metal including copper, zinc, or a combination thereof. Methods of making such a composition are also described, along with devices which use the composition to remove contaminants from fluid streams, particularly in vehicle tunnels and parking garages.

A resin film for a power storage device that is arranged between an exterior material of a power storage device and a power storage device element, the resin film for a power storage device including a water absorbent.

Disclosed herein is a composite material formed from an inorganic mesoporous, or mesoporous-like, material that is dispersed throughout a polymeric matrix formed by a crosslinked polymer that has acidic- or basic-residues and which may also optionally have further acidic- or basic-residues grafted onto the inorganic mesoporous material. The resulting composite material may be used to remove acidic or basic impurities from a gas in need thereof and can be easily regenerated.

A family of highly charged crystalline microporous metallophosphate molecular sieves designated PST-19 has been synthesized. These high charge density metallophosphates are represented by the empirical formula of:

R.sup.p+.sub.rA.sup.+.sub.mM.sup.2+.sub.xE.sub.yPO.sub.z

where A is an alkali metal such as potassium, R is an organoammonium cation such as tetraethylammonium, M is a divalent metal such as zinc and E is a trivalent framework element such as aluminum or gallium. The PST-19 family of materials are among the first MeAPO-type molecular sieves to be stabilized by combinations of alkali and quaternary ammonium cations, enabling unique compositions. The PST-19 family of molecular sieves has the SBS topology and catalytic properties for carrying out various hydrocarbon conversion processes and separation properties for separating at least one component.

A xenon capture system that reduces the concentration of xenon in a carrier gas is disclosed. An example xenon capture system includes a carrier gas with a first concentration of xenon that flows through an intake into a chamber. Within the chamber is a reaction area that has at least one peripheral sidewall. The reaction area operates at a predetermined temperature, flow rate, and low pressure. Within the reaction area is at least one xenon capture mechanism that is at least partially formed of a transition metal. When the carrier gas is exposed to the xenon capture mechanism, the xenon capture mechanism adsorbs xenon from the carrier gas. The carrier gas, with a second concentration of xenon, exits the chamber through the exhaust outlet.

The present invention relates to a preparation method of an organic-inorganic nanoporous material-metal chloride hybrid moisture adsorption composition, and the moisture adsorption composition prepared by the preparation method. More specifically, an embodiment of the present invention provides a preparation method of the moisture adsorption composition, the preparation method comprising the steps of crystallizing an aluminum precursor and a dicarboxylic acid organic ligand to synthesize an organic-inorganic nanoporous material, heat-treating the organic-inorganic nanoporous material to remove unreacted organic materials, mixing the heat-treated organic-inorganic nanoporous material with a metal chloride solution to impregnate particles of the organic-inorganic nanoporous material with a metal chloride, drying the mixture in an oven, thereby removing a solvent from the mixture to obtain a dried product, crushing the dried product to obtain a powder, and vacuum drying the powder to remove residual moisture from the powder. The moisture adsorption composition according to an embodiment of the present invention can be applied to an air conditioner, an adsorption type refrigerator, a dehumidifier, and a cooling and heating device by having a maximum moisture adsorption amount (the amount of moisture adsorbed per unit weight of the adsorption composition) of 0.2 to 0.9 g/g in the driving pressure range (P/P.sub.0=0.1 to 0.3).
