A porous polymer aerogel, wherein the aerogel has greater than 5 wt % of amine containing vinyl monomers integrated into a polymer backbone. A method of fabrication of a porous polymer aerogel amine material, includes preparing a solution comprising at least a solvent, amine monomers having protected amino groups, one or more crosslinkers, one or more radical initiators, and a nitroxide mediator, removing oxygen from the solution, heating the solution to promote polymerization and to produce a polymerized material, performing solvent exchange with the polymerized material, causing a deprotection reaction in the polymerized material to remove groups protecting the amino groups, soaking and rinsing the material to remove excess reagents and any byproducts of the deprotection reaction, and drying the material to produce the amine sorbent. A system to separate CO2 from other gases, comprising a polymer porous aerogel sorbent having greater than 5 wt % of amine containing vinyl monomers integrated into a polymer backbone.

The subject matter disclosed herein relates generally to microdenier fabrics comprising fibrillated bicomponent fibers. The bicomponent fibers can be fibrillated mechanically by hydroentangling, where the hydroentangling energy is sufficient for fibrillating as well as entangling or bonding the fibers. The bicomponent fibers can have an island-in-the-sea configuration. The micro-denier fabrics can be woven, knitted, or nonwoven. A nonwoven fabric made from the bicomponent fibers can be formed by either spunbonding or through the use of bicomponent staple fibers formed into a web by any one of several means and bonded similarly to those used for the spunbonded filament webs.

A method and microfluidic device with a porous polymer monolith in a channel of the device with capture affinity element (such as an oligonucleotide complementary to a DNA target from the KPC antibiotic resistance gene) on the monolith surface.

The present disclosure provides a means to remove oxidative compounds such as free halogen and chloramines from a liquid, while also providing components with antimicrobial properties in order to combat biofouling and the shedding of pathogens into liquids. In particular, methods of removing an oxidative compound from a liquid in which the liquid is contacted with one or more polymeric beads. As described herein, the oxidative compound binds to the polymeric bead and is removed from the liquid.

A composite virucidal filter media is described. The filter media comprises a fibrous substrate comprising a plurality of intermingled fibers, a low cost, nontoxic, hydrophilic polymer without acidic functional groups deposited on a surface of the fibers without the formation of a continuous coating layer on the substrate, and a virucidal metal, a virucidal metal-containing compound, or combinations thereof deposited on the surface of the fibers comprising the hydrophilic polymer without acidic functional groups. The hydrophilic polymer without acidic functional groups can be charged or non-charged. Methods of making virucidal fibrous filter media are also described.

A mesoporous organic material which makes it possible to extract, using the liquid-solid extraction technique, the uranium(VI) contained in an aqueous medium including phosphoric acid, with high efficiency and high selectivity for the iron that the medium can likewise contain. The material is likely to be obtained by cross-linking polymerisation of a monomer of formula (I) below, wherein: R.sup.1, R.sup.2 and R.sup.3 are, independently from one another, H, a C.sub.1 to C.sub.12 saturated or unsaturated, linear or branched hydrocarbon group, or a polymerisable group, with the condition that at least one of R.sup.1, R.sup.2 and R.sup.3 is a polymerisable group; R.sup.4 and R.sup.5 are, independently from one another, H or a C.sub.1 to C.sub.8 saturated or unsaturated, linear or branched hydrocarbon group; the cross-linking polymerisation being carried out in the presence of a cross-linking agent and one or more pore-forming agents.

A chromatography medium includes a porous matrix and nonporous globules bound on the inner and outer surfaces of the porous matrix. The average radius of the microglobules is not more than 30% of the average pore diameter of the porous matrix. The chromatography medium can be used in affinity chromatography. A method for preparing the chromatography medium may include providing a porous starting matrix, providing a polymerization solution, and initiating polymerization of the polymerization solution in the presence of the porous starting matrix to form insoluble nonporous microglobules that are bound to the inner and outer surfaces of the porous starting matrix.
