A thin film getter is provided. The thin film getter comprises a substrate and an absorption layer on the substrate, wherein the absorption layer comprises a getter material for absorbing target gas and an auxiliary material for providing a moving path of the target gas, and the getter material can be divided into a plurality of getter regions by the auxiliary material.

A process for recovery of lithium ions from a lithium-bearing brine includes contacting the lithium-bearing brine with a lithium ion sieve (where that LIS includes an oxide of titanium or niobium) in a first stirred reactor to form a lithium ion complex with the lithium ion sieve, and decomplexing the lithium ion from the lithium ion sieve in a second stirred reactor to form the lithium ion sieve and an acidic lithium salt eluate.

Provided is a filter having either or both of a winding and a laminate that include a fiber-like absorbing material, wherein the fiber-like absorbing material has a base material and metal particles supported on the base material, and the diameter D of the fiber-like absorbing material, the void fraction of the winding or laminate, and the variation in the area void fraction in the radial direction of the winding or the variation in the area void fraction in the direction of lamination are in a specific range.

The invention relates to devices, systems, and methods for precision recharging of sorbent materials in a sorbent module. The devices, systems, and methods use manufacturing characteristics of the sorbent module to set recharge parameters used in recharging the sorbent material.

Provided herein are compounds, compositions, and methods for the treatment of wastewater. Provided herein are compounds, composites, compositions, and methods for purifying a medium such as wastewater, saline for desalination, and petroleum wastes.

The method according to this disclosure is a method for separating an unsaturated hydrocarbon having 2 or 3 carbon atoms and a halogenated unsaturated carbon compound formed by replacing at least one of hydrogen atoms included in the unsaturated hydrocarbon with a fluorine atom, from each other and is a method for selectively adsorbing either the unsaturated hydrocarbon or the halogenated unsaturated carbon compound by a porous coordination polymer that includes a metallic ion having a valence of 2 to 4 and an aromatic anion having 1 to 6 aromatic ring(s).

The present disclosure is directed to methods for scrubbing low levels of urea from aqueous solutions such as a dialysate from dialysis, and including blood and blood products, and devices capable of employing these methods.

Adsorbents of varying types and forms are described, as usefully employed in gas supply packages that include a gas storage and dispensing vessel holding such adsorbent for storage of sorbate gas thereon, and a gas dispensing assembly secured to the vessel for discharging the sorbate gas from the gas supply package under dispensing conditions thereof. Corresponding gas supply packages are likewise described, and various methods of processing the adsorbent, and manufacturing the gas supply packages.

Provided is a method of designing a low-pressure chamber that provides a preset air pressure corresponding to a predetermined altitude. The method may include the steps of: calculating a predetermined error range of the preset air pressure, and calculating an amount and types of materials of a getter to be inserted into the low-pressure chamber based on the error range and a total volume of the low-pressure chamber.

An exhaust gas purifying composition of the present invention contains zeolite that is BEA zeolite having an SiO.sub.2/Al.sub.2O.sub.3 molar ratio of greater than 25 and 600 or less and containing phosphorus. Furthermore, the exhaust gas purifying composition preferably contains zirconium in addition to phosphorus. Furthermore, the zeolite has an SiO.sub.2/Al.sub.2O.sub.3 molar ratio of from 30 to 150. The present invention provides an exhaust gas purifying composition having excellent HC adsorbability for exhaust gas purification in internal combustion engines such as gasoline engines.
