Provided herein are methods of making an adsorbent bed useful as a micro-reactor, or a catalytic and/or separation device. The adsorbent bed comprises a metal-organic framework composite. In the present methods, one or more metal-organic frameworks in powder form are mixed in a liquid to produce a metal-organic framework suspension or other type of metal-organic framework coating. A monolith is coated with the suspension or coating to provide the metal-organic framework composite having at least one metal-organic framework coating layer deposited on and bounded to the monolith. The metal-organic framework composite produced has a BET surface area of about 1 m.sup.2/g to about 300 m.sup.2/g and/or a comparative BET surface area of about 40% to about 100% relative to the metal-organic framework monolith, and pore size between about 1 nm and about 50 nm.

Methods of preparing polymer-filled chromatography resin and their uses are provided.

A method for preparing, in the internal volume of at least one channel, a monolithic support on which uranyl cations are immobilised. The method comprises: (a) activating the inner surface of the channel(s); (b) introducing, into the internal volume of the channel(s), a polymerisation solution comprising: a monomer comprising a phosphate group, at least one crosslinking agent, several solvents, and a radical polymerisation initiator; (c) polymerising the polymerisation solution; (d) rinsing the monolithic support obtained in step (c); and (e) contacting the monolithic support previously rinsed, with a solution comprising uranyl cations. A method for capturing proteins that selectively bind uranium by means of a monolithic support prepared by the above-mentioned method, as well as to a method for recovering proteins that selectively bind uranium with the capture method.

A method of manufacturing a hydrocarbon absorbent structure comprises providing a lower sheet of material and dispensing a hydrocarbon absorbent polymer mixture thereon. The polymer mixture is then preheated so as to at least partially melt the polymer mixture. An upper sheet of material is then provided onto the at least partially melted polymer mixture on the lower sheet of material. The lower sheet of material, polymer mixture and upper sheet of material are then laminated together to form a hydrocarbon absorbent laminate structure.

The methods of the invention employ targeted magnetic particles, preferably targeted nanomagnetic particles, and targeted buoyant particles such as buoyant microparticles and microbubbles. Among the benefits of the invention is the ability to combine targeted magnetic particles with differentially targeted buoyant particles to achieve separation of two or more specifically cell targeted populations during the same work flow.

The chromatographic materials of the invention are chromatographic materials comprising having a narrow particle size distribution.

A method of synthesizing a medium for fast, selective oil-water separation and/or oil absorption comprises providing a toluene solution containing a polymer or a polymer mixture; immersing porous wool-like structure (PW) in the toluene solution for a period of time; and removing the immersed PW from the toluene solution, and heat-treating the immersed PW to obtain the medium comprising polymer-modified PW, wherein the polymer or the polymer mixture is adapted such that the medium is a superwetting material that is superhydrophobic and superoleophilic under water or salty water.

Spike particles are disclosed including a core and a plurality of spikes attached to and extending from a core surface. The core may be nonporous, superficially porous, or porous. The plurality of spikes may be nonporous or superficially porous. Superficially porous spike particles are disclosed including a porous spike particle shell disposed over a nonporous spike particle. A method for forming the spike particles is disclosed including mixing a dispersed aqueous phase having a plurality of core particles, a water emulsion drop stabilizer, and a catalyst with a continuous oil phase having an organic solvent, polyvinylpyrrolidone, and a silane precursor to form a water-in-oil emulsion system, which is reacted without stirring to form the plurality of chromatographic spike particles. A chromatographic separation device is disclosed including the spike particles, which are randomly packed in the chromatographic separation device and have an external porosity ranging from about 0.4 to about 0.9.

Magnetic nanoparticle coated porous materials for recovering a contaminant from contaminated water are provided. In embodiments, such a material comprises a porous substrate having a solid matrix defining a plurality of pores distributed through the solid matrix and further comprising a coating comprising magnetic nanoparticles on surfaces of the solid matrix.

An antimicrobial filter media, which includes a non-woven fabric; and an antimicrobial agent bound to the nonwoven fabric by a binder, the antimicrobial agent including silver sodium zirconium hydrogenphosphate and thiabendazole, and the silver sodium zirconium hydrogenphosphate and the thiabendazole are employed at a weight ratio of 1:1.5 to 1.5:1, to an air cleaner including the same, and to a process for preparing the same.
