The purpose of the present invention is to adsorb calciprotein particles. An adsorbent for calciprotein particles of the present invention is characterized in that the surface of a water-insoluble carrier is covalently bonded, through a hydrocarbon group, to at least one selected from the group consisting of amino group, carboxyl group, phosphate group, phosphono group, phosphino group, and thiol group.

Compositions and methods are described for self-assembled polymer materials having at least one of macro, meso, or micro pores.

A composite absorbent filter media having adsorption and/or absorption properties for the filtration of ester oils from a liquid includes a graphene and/or graphite composite mixed into a final emulsion, which is subsequently heat treated or cured, cooled, compressed, and dried. The resultant adsorption/absorption media is then disposed within a plug structure having an ingress and egress for liquids mixed with ester oils to pass through. Alternatively, the resultant adsorption/absorption media is disposed into a fabric and formed as a wall used to enclose oil-filled equipment. The media adsorbs/absorbs the ester oils from the liquid, while allowing the liquid to disperse and pass through.

Composite particles contain a natural stone or aggregate core and a coating of two or more sorbent layers collectively containing at least two distinct kinds of sorbent materials effective for sorbing two distinct contaminants. One or both sorbent layers may be mixed with a water-absorbent, swellable clay that, upon contact with water, causes spalling or disintegration of the coating layer to release the sorptive material into a body of water such as a pond, ditch, stream, or riverbed. Additional swellable or protective layers may also be present. The composite particles are deployed into a pond, ditch, river, or streambed where the core of natural stone remains in the riverbed. The sorptive materials of the two different sorbent layers sorb and fix a wide range of contaminants, including both the heavy and light-weight hydrocarbons, from the water, and settle as a fine sediment. The sediment with sorbed contaminants is then removed by means such as hydraulic collectors or dredging.

The present invention relates to systems and methods for controlling the atmosphere in the cabin (1) of a vehicle. The system comprises a carbon dioxide removal conduit (2) comprising a regenerable carbon dioxide removal chamber (5,6) containing a carbon dioxide sorbent material and a regeneration circuit (7) arranged to expel the desorbed carbon dioxide at a location exterior (8) of the cabin (1) The system is operable to maintain a carbon dioxide level below 1000 ppm in the passenger cabin for a period of at least 5 minutes while restricting the flow of air from outside the vehicle into the passenger cabin to 10 L/s or less.

The invention relates to polymer chemistry, specifically to polymer sorbents intended for selective removing cytokines and bacterial endotoxins from whole blood and other body liquids, in particular blood plasma, lymph etc., as well as from aqueous protein solutions and aqueous organic compound solutions, also containing inorganic salts, as well as to method of producing such sorption materials and the method of sorbtion processing liquids using said polymer sorbents. Technical result consists in providing a sorbent that is able to remove both cytokines and bacterial endotoxins, in improving selectivity of the polymer sorbents in respect to said compounds as well as in providing a simple and effective method of producing said sorbent.

Wound dressings, methods for forming the wound dressings, and methods for using the wound dressings are described. Wound dressings include a polymeric composition that includes a biocompatible polymer and a pH indicating agent. The polymeric composition can be at a wound contacting surface of a wound dressing in the form of, e.g., a fiber, a hydrogel, or a microsphere. The color of the polymeric composition as determined by the pH indicating agent can indicate the presence of infection or a chronic wound state. The wound dressings can be used for early detection of healing abnormalities in acute, chronic, or burn wounds.

A nanoclay based solid sorbent is provided having a nanoclay with at least one surface, and at least one amine containing compound wherein the amine containing compound is attached to the surface, as well as a method of making it. A method of capturing carbon dioxide gas is disclosed includes passing a gas from an effluent process stream containing carbon dioxide through the nanoclay based solid sorbent and capturing the carbon dioxide gas on the surface and within the nanoclay based solid sorbent. The nanoclay based solid sorbent having the captured carbon dioxide gas is regenerated by undergoing one or more cycles of desorption of the captured carbon dioxide gas from the nanoclay. The regenerated nanoclay based solid sorbent may then be reused.

Disclosed are a preparation method of a carbon dioxide capture agent and an application thereof. The method includes: mixing a graphite dispersion, an organic acid solution, a metal salt solution and a silica sol to obtain an organic-inorganic composite gel; standing and aging the organic-inorganic composite gel, drying the same and then carbonizing the same by microwave in a mixed atmosphere of inert gas and sulfur dioxide to obtain an intermediate product; and subjecting the intermediate product to acid washing or alkali washing to obtain a defective carrier, then mixing the defective carrier with an amine substance for ultrasonic treatment and drying to obtain the carbon dioxide capture agent.
