The invention relates to a method to produce a particulate activated carbon material for capturing CO.sub.2 from air,

wherein the particulate activated carbon is impregnated with alkali carbonate salt such as K.sub.2CO.sub.3; and wherein the impregnated particulate activated carbon either has, determined using nitrogen adsorption methods, a pore volume of at least 0.10 cm.sup.3/g for pore sizes of at least 5 nm and a pore volume of at most 0.30 cm.sup.3/g for pore sizes of less than 2 nm or is based on a mixture of different alkali carbonate salts, or has a particular pore surface for pore sizes in the range of 2 nm-50 nm.

Sample preparation and separation can be performed using a sample cartridge (201). The cartridge includes a barrel (204) with a first and second end, a column segment (209) connected to the second end of the barrel, and a column (205) containing a sorbent material. The sorbent material includes particles that have antibodies attached to them to selectively retain analytes, proteins attached to them to retain certain classes of antibodies, or enzymes attached to them to perform specific modifications to certain classes of molecules. The column segment can be in thermal communication with a temperature control device in order to control the temperature of the column.

The process of reacting nanoscale ce-MoS.sub.2 nanosheets anchored on oxide support with lead in solution at room temperature whereby the reaction is rapid and spontaneous resulting in the formation of PbMoO.sub.4-xS.sub.x in the process of scavenging Pb.sup.2+ and Pb.sup.4+ present in the solution.

The present technology relates to a method for improved recovery of phosphorylated compounds (e.g., phosphorylated glycans). In particular, the present technology utilizes certain chelator additives in a solution to wash and elute the phosphorylated compounds from a solid phase extraction cartridge.

A system and method for removing undesirable organic compounds so that the desirable cannabinoids, terpenes, and any other beneficial organic compounds can be easily and effectively captured is provided herein. The system and method makes use of bentonite clay, silica gel and magnesium silicate filters through which a solution containing the organic compounds is rinsed with liquid non-polar solvent. The undesirable components remain in the bentonite clay, silica gel and magnesium silicate while the beneficial organic compounds pass through and are collected in a liquid solution.

Methods and devices for providing dialysis treatment are provided. The device comprises a cartridge for providing regenerative dialysis, the cartridge comprising: a body having an inlet and an outlet and defining an interior, the interior including at least a layer comprising urease, a layer comprising zirconium oxide, a layer comprising zirconium phosphate, and a layer comprising carbon, wherein at least two of the layers are blended together to provide a gradient of the two materials.

A water purification apparatus and a water purification method capable of effectively using a layered double hydroxide and easily being applied are described. A water purification apparatus for removing a polluted substance from polluted water includes a solid-liquid separator that separates the polluted water and a solid material from each other, and a polluted substance remover that removes, by a layered double hydroxide, the polluted substance contained in the polluted water separated by the solid-liquid separator.

A device and a method for stabilizing wine or other vegetable beverages by removal, in whole or in part, of agents responsible for instability, including proteins and metals, are provided. The device has a tubular container filled internally at least partly with particles of support material covered with a layer of a mesoporous nanostructured adsorbent material comprising titanium oxide, adapted to absorb proteins and metals.

An object of the present invention is to provide a ligand-immobilized sea-island composite fiber in which generation of fine particles due to peeling of a sea component from an island component and generation of fine particles due to destruction of a fragile sea component are both suppressed. The present invention provides a sea-island composite fiber comprising a sea component and island components, in which a value (L/S) obtained by dividing the average total length (L) of the perimeter of all island components in a cross section perpendicular to the fiber axis by the average cross-sectional area (S) of the cross section is from 1.0 to 50.0 μm.sup.−1, a distance from the surface to the outermost island component is 1.9 μm or less, and an amino group-containing compound is covalently bonded to a polymer constituting the sea component at a charge density of 0.1 μmol or more and less than 500 μmol per 1 gram dry weight.

Provided are a water-absorbing wipe and a manufacturing method therefor. The water-absorbing wipe has upper and lower layers of melt-blown fiber webs, and an intermediate layer of a wood pulp fiber web containing a super absorbent resin, wherein melt-blown fibers of the melt-blown fiber webs are woven into the wood pulp fiber web. The super absorbent resin in the water-absorbing wipe can rapidly absorb water or detergent. During wiping, by virtue of the liquid retention ability of the super absorbent resin, the water or the detergent is slowly released to the surface of an object to be cleaned, such that stains can be rapidly removed due to the wetness of the wipe. Moreover, after absorbing a large amount of water or detergent, the wipe can keep the surface dry without leaving behind drops of liquid, and is more suitable for use when the wipe is wet.
