The present disclosure relates to carbon nanotube based desalination membranes and methods of manufacturing thereof. The carbon nanotube based desalination membranes may be manufactured by: providing a polymer matrix; providing carbon nanotubes directly contacting the polymer matrix; stirring the carbon nanotubes into the polymer matrix in order to make a carbon nanotube composite solution; and coating a substrate with the carbon nanotube composite solution to form a carbon nanotube desalination membrane. The carbon nanotube based desalination membranes may provide superior flow rate and high levels of salt rejection.

An air remediation device includes a housing including an internal chamber, an inlet, an outlet, and a potting material dividing said internal chamber into a first compartment and a second compartment. At least one hollow fiber membrane is supported by the potting material and held in the first compartment. Airborne viral particles are directed (a) through the inlet into the first compartment and then (b) through the at least one hollow fiber membrane, where the airborne viral particles are captured to produce treated air, and then the treated air is directed (c) through the second compartment before being exhausted from the housing through the outlet.

An asymmetric hollow fiber membrane for oxidative coupling of methane reactions.

A gas separation membrane including a separation functional layer in at least part thereof, the gas separation membrane having a fibrous shape or film-like shape, the separation functional layer including a matrix and particles. Provided are a gas separation membrane and a gas separation membrane module capable of preventing breakage of the gas separation membrane during the operation, and allowing long-term stable production of excellent permeation and separation properties.

Compositions, devices, and methods relating to the use of mixed-matrix membranes containing metal-organic frameworks to separate gases are generally described. In some embodiments, branched nanoparticles made at least in part of metal-organic frameworks are described. In some embodiments, the morphology and size of the branched nanoparticles are controlled by the presence of a chemical modulator during synthesis. In some embodiments, the branched nanoparticles are uniformly distributed in a mixed-matrix membrane. In some embodiments, the mixed-matrix membrane is configured to separate one or more gases from a gas mixture. In some embodiments, the branched nanoparticles contribute at least in part to an increase in permeability, selectivity, and/or resistance to plasticization of the mixed-matrix membrane.

The present disclosure is directed to a potassium-form MER framework type zeolite, a MER framework type zeolite having a stick-like morphology, wherein the potassium is present as K.sup.+ in extra-framework locations. The zeolite is essentially free of an extra-framework cation other than potassium.

The present disclosure relates to the field of materials for uranium extraction from seawater (UES), and in particular, to a photothermal photocatalytic membrane for seawater desalination and uranium extraction and a preparation method therefor. The present disclosure provides a photothermal photocatalytic membrane for seawater desalination and uranium extraction and a preparation method therefor. The preparation method includes: fixing a treated carbon cloth to a glass plate, pouring a casting solution 1 onto the carbon cloth to form a first layer of film, forming a second layer of film using a casting solution 2, and putting the second layer of film into a first coagulation bath and a second coagulation bath in sequence to form the photothermal photocatalytic membrane. The photothermal photocatalytic membrane is supported by the carbon cloth, and a surface of the photothermal photocatalytic membrane is of a micro-nano structure.

Provided herein are, inter alia, biological manufacturing and downstream purification processes.
