Disclosed herein is a process for manufacturing a material, in accordance with some embodiments. Accordingly, the material facilitates a reduction of pollutants from air. Further, the process may include heating natural zeolite to at least one hundred degree celsius for a predetermined duration of time. Further, the heating removes at least one impurity from the natural zeolite. Further, the process may include producing purified natural zeolite based on the heating. Further, the process may include grinding the purified natural zeolite into particles based on the producing. Further, the process may include incorporating the particles of the purified natural zeolite into a grind paste based on the grinding. Further, the incorporating produces the material.

Disclosed are compositions for use in the simultaneous removal of endotoxins from dialysate and uremic solutes from blood during the treatment of patients. The treatment is selected from the group consisting of hemodialysis and hemodiafiltration. The compositions comprise sorbent particles embedded in a membrane comprising a polymer and a hydrophilic additive.

To adsorb a substance to be treated in a fluid (7) with a higher adsorption capacity and lower pressure loss, an adsorptive sintered compact (20) includes powder adsorbent materials (1a, 1b), and resin structures (2) in which voids (3) are formed in a three-dimensional network. The powder adsorbent materials (1a, 1b) include free adsorbent materials (1a) free-movably contained in the voids (3) between the resin structures (2), and fixed adsorbent materials (1b) fixed to a surface (2a) of the resin structure (2) and/or at least partly embedded inside the resin structure (2), and the powder adsorbent materials (1a, 1b) are at least one of powdered activated carbon, powdered activated clay, and zeolite.

Polyvinyl alcohol-based fibers contain a polyvinyl alcohol-based polymer and an adsorbent. With respect to 100 parts by mass of the polyvinyl alcohol-based polymer, 30 to 500 parts by mass of the adsorbent is contained. The polyvinyl alcohol-based fibers have a crystallinity of polyvinyl alcohol ranging from 30% to 60%, a diameter ranging from 5 μm to 1000 μm, and a specific surface area ranging from 10 m.sup.2/g to 2000 m.sup.2/g.

In an example, a print system include a component device that is operation in a number of state, a density engine, and a component engine. An example density engine identifies a plane region of a plane where print fluid is to be printed based on data of a print job and determines a density classifier for the plane based on a location of the plane region on the plane. An example component engine causes an adjustment of a component attribute of the component device based on the density classifier.

A method of encapsulating an engineered pellet in a porous membrane is disclosed. The method includes the steps of: (i) dissolving a membrane solute in a membrane solvent to produce a membrane solution; (ii) applying the membrane solution to a pellet to form a pellet encapsulated with the membrane solution; (iii) subjecting the membrane solution that encapsulates the pellet to a phase inversion and; (iv) drying the pellet to form a porous membrane encapsulated pellet. A porous membrane encapsulated pellet is also described.

Dangerous, toxic, and/or radioactive volatiles are produced from nuclear fission, nuclear decay, and/or as a byproduct from vitrification of radioactive wastes. Such volatiles are treated during and after vitrification of the radioactive waste, to be converted into fixed-chemicals, that are retained in, on, and/or proximate to a cold-cap located vertically above vitrified melt. The cold-cap may have one or more volatile fixing additives (VFAs) for retaining the fixed-chemicals. The VFAs are located in and/or the cold-cap. The vitrification may occur within at least one human-made cavern. The human-made cavern may be located within a deep geologic rock formation. The deep geologic rock formation may be located at least 2,000 feet below a terrestrial surface of the Earth. The human-made cavern may be formed by first drilling a wellbore from the terrestrial surface to the deep geologic rock formation and then underreaming the wellbore into the deep geologic rock formation.

This invention provides processes for reducing the environmental availability of one or more environmental pollutants in solids, liquids, and combinations of solids and liquids.

Adsorbent compositions comprising one or more copper oxides and one or more iron oxides are effective towards removing CO from process streams at temperatures below 100° C., for instance olefin process streams. A method of removing CO from a process stream comprises contacting the stream with the adsorbent composition comprising one or more copper oxides and one or more iron oxides.

A thermal storage composition is defined by a polymer having thermally responsive absorption or passage capabilities based on an Upper Critical Solution Temperature (UCST) or Lower Critical Solution Temperature (LCST), and a sorbent in fluidic communication with the polymer. A fluid such as water conveys thermal energy between the polymer and the sorbent based on an identified target temperature that acts as a thermostat for synergistic fluid release and transfer between the polymer and sorbent that stores and releases heat energy in a cyclic manner. The composition includes a synergistic integration of a sorbent and selectively hydrophilic polymer to alternately hydrate according to a target temperature based on the UCST of the water/sorbent combination.
