A process for the efficient transfer of molecules between phases employing mesoporous poly (aryl ether ketone) hollow fiber membranes is provided. The method addresses the controlled transfer of reactants into and removal of reaction products from a reaction media and the removal and separation of target molecules from process streams by membrane-assisted liquid-liquid extraction. A number of possible modes of liquid-liquid extraction are possible according to the invention by utilizing porous poly (aryl ether ketone) hollow fiber membranes of Janus-like structure that exhibit a combination of hydrophilic and hydrophobic surface characteristics. The method of the present invention can address the continuous manufacture of chemicals in membrane reactors and is useful for a broad range of separation applications, including separation and recovery of active pharmaceutical ingredients.

A composite material of polyurethane foam having a layer of reduced graphene oxide and polystyrene is described. This composite material may be made by contacting a polyurethane foam with a suspension of reduced graphene oxide, drying, and then irradiating in the presence of styrene vapor. The composite material has a hydrophobic surface that may be exploited for separating a nonpolar phase, such as oil, from an aqueous solution.

The present invention relates to a lectin-macromolecular carrier coupling complex for separating glycosylated exosomes from a clinical sample, which comprises a macromolecular carrier and lectins coupled to the outer side of the macromolecular carrier. The complex may simply, conveniently, rapidly, and accurately separate glycosylated exosomes from a clinical sample with a high separation efficiency and a good repeatability; and the separated exosomes are intact in morphology without rupturing or cracking, may be directly used for liquid detection of glycosylated exosomes, or directly used for immunology-related detection, or directly used for gene detection or analysis after extracting related nucleic acids from the exosomes.

The present invention concerns a perovskite solar cell provided with a polymer-porous template composite material for absorbing toxic metal ions. Preferably, the porous template material is a metal oxide framework (MOF) material. An example of a preferred polymer-porous template composite material is PDA-Fe-BTC (polydopamine-Fe1,3,5-benzenetricarboxylate). In experiments mimicking breakage of the solar cell modules, the presence of the polymer-MOF material was shown to result in the capture of lead and thus to reduced leakage of lead.

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.
