The present invention relates to a sheet filter material, in particular having an aerosol filter function and/or a particle filter function, preferably having a protective function against chemical, biological and/or chemical harmful and toxic substances, and to a method for the production thereof. The sheet filter material is particularly suitable for producing protective equipment, protective objects, sports and leisure clothing and filters and filter materials of all types.

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.

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. The antimicrobial filter media includes silver sodium zirconium hydrogenphosphate and thiabendazole, as an antimicrobial agent, at a specific weight ratio. As a result, it is possible to effectively filter harmful microorganisms to supply purified air, to have excellent antibacterial, antiviral, and antifungal properties at the same time, and to further enhance the durability and lifespan characteristics by virtue of excellent filter damage prevention effect.

A filter is disclosed. The filter of the present disclosure includes: a support layer; and a filter layer coupled to the support layer, wherein the filter layer is formed by a melt blown method with, as a melt, a thermoplastic resin-including first base and a first antibacterial agent, wherein the first antibacterial agent includes an antibacterial metal or antibacterial metal oxide.

A solid fiber is described, where the solid fiber is characterized by (a) a modification degree Do/Di, in a cross section of the solid fiber of 1.20 to 8.50 where the inscribed circle diameter is denoted by Di and the circumscribed circle diameter is denoted by Do; and (b) a porous specific surface area of not less than 30 m.sup.2/g.

A relatively fast, inexpensive, and non-destructive method for separation and isolation of biologically active nanoparticles is described. Methods include the use of solid phase separation medis such as channeled fibers in a hydrophobic interaction chromatography (HIC) protocol to isolate biologically active nanoparticles from other components of a mixture. Biologically active nanoparticles can include natural nanoparticles (e.g., exosomes, lysosomes, virus particles) as well as synthetic nanoparticles (liposomes, genetically modified virus particles, etc.)

A chromatograph is provided for identifying components of a mixture. Components are identified by different rates of adsorption and/or desorption with a material phase. In one embodiment, an electrical lead is connected to the material phase for supplying an electrical charge to the material phase. The electrical charge alters the rate of adsorption/desorption of the components with the material phase. In another embodiment, the material phase is disposed between two conductors with electrical leads connected to each of the conductors. A charge differential between the two conductors alters the rate of adsorption and/or desorption of components with the material phase.

The present invention provides a covalent-organic framework (COF) body, populations of such bodies, a method for manufacturing a covalent-organic framework (COF) body, and (a) a gas storage system or a gas separation system comprising a gas storage vessel and a population of such COF bodies. The COF body comprises a plurality of primary COF particles, some or all of the primary COF particles being agglomerated as COF agglomerates. The average diameter of the primary COF particles is between nm and 120 nm, and the average diameter of the agglomerates is larger than the average diameter of the primary COF particles and between 15 nm and 250 nm. By careful control over particle size distribution during the formation of the COF material, it is possible (b) to form COF materials into high bulk density shapes and forms which are industrially useful and practical without losing sorbent performance.

A sintered elastomeric material combined with at least one absorbent material and formed into a thin compressible sheet. The material finds particular use in venting or filtering gasses. In specific examples, the elastomeric material may be a thermoplastic elastomer and the absorbent material may be carbon. When an amount of carbon (or any other type of conductive material) included with the elastomeric material is high enough, the material may also find use as a conductive material.

Described are multi-layer filters of a type commonly known as “depth filters” and related devices and methods, with the filters containing a layer that includes polyaramid fiber, synthetic filter aid, and polymeric binder.
