A membrane capsule for biological and chemical separations comprising a cassette comprising an upper surface and a lower surface adjoined by a cassette sidewall, an inlet and an outlet located on the upper and lower surfaces of the cassette, tubes fluidly connected to the inlet and the outlet, holes or slots in the tubes to facilitate separation, and a membrane wrapped, pleated, and/or spiral wound around each of the tubes. Methods of separation comprising flowing fluid flow through the inlet of the membrane capsule, allowing the fluid to permeate through the holes or slots of the tubes, separating biological and/or non-biological substances, collecting the fluid within a reservoir, and draining fluid from the reservoir.

Disclosed is a method of modifying a metal-organic framework (MOF), the modified MOF, and methods for using the same. The method of modification can include heating a mixture comprising an azide compound and a MOF to generate a nitrene compound and nitrogen (N2) from the azide compound and covalently bonding the nitrene compound to the MOF to obtain the modified MOF.

A method for the treatment of a substrate; the substrate comprises hollow fibre membranes, each of which has a side wall, comprising a base material, and an inner lumen, which is delimited by the side wall; the base material comprises a polysulfone or a derivative thereof; the substrate is placed in contact with graphene oxide in the presence of a liquid so as to obtain an intermediate compound, from which the liquid is at least partially removed and which is thermally treated so that the graphene oxide is at least partially fixed to the substrate and a treated material is obtained comprising treated fibres.

A washable multi-layer composite capable of fluid containment that may be used to protect a surface from liquid infiltration

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 chromatography system comprising at least two chromatography units (3) connected in parallel, wherein said at least two chromatography units (3) each comprises a convection-based chromatography material, wherein an initial difference in back pressure provided from the different chromatography units (3) is compensated dynamically during run of the system due to a change of chromatography unit properties provided during the chromatography process.

The present invention is directed to a method of capturing CO2 from a FCC regenerator using select membranes.

A filtering and adsorbent sampling and enrichment system comprising a stationary phase consisting of a felt of activated carbon fibres with a micro-meso porous conformation and specific surface area of about 1500 m2/g and sampling and/or enrichment standards, confined within a closed casing, is described, as well as the method for obtaining it and the relative process for the analysis of organic and inorganic analytes that uses said system.

The disclosure discloses an anti-haze anti-harmful gas air filter membrane as well as a preparation method and application thereof. The air filter membrane comprises a nano fiber membrane made of nano fibers and having a two-dimensional or three-dimensional network structure. The nano fiber membrane can be a high-molecular polymer nano fiber membrane prepared by utilizing an electrostatic spinning process, and can also be doped with an organic or inorganic additive capable of adsorbing and absorbing harmful gases, such as VOCs, NO.sub.x, SO.sub.x and NH.sub.3, in the air and/or a photocatalyst capable of degrading these harmful gases in a photocatalysis manner, or the like. The anti-haze anti-harmful gas air filter membrane disclosed by the disclosure can efficiently filter PM2.5 and PM10 particulate pollutants and the like in the air and simultaneously can efficiently identify and clear multiple harmful gases in the air. The anti-haze anti-harmful gas air filter membrane has a wide application prospect in the field of air purification, for example, can be applied to air purification devices, such as screen windows, gauze masks and filter screens.
