A separation membrane module includes a monolith type reactor, a housing, an annular first sealing portion and an annular second sealing portion. The monolith type reactor extends in a longitudinal direction and is configured to be used for a conversion reaction for converting a source gas into a liquid fuel. The annular first sealing portion seals a gap between the housing and a first end portion of the reactor in the longitudinal direction. The annular second sealing portion seals a gap between the housing and a second end portion of the reactor in the longitudinal direction. The first sealing portion is deformable or movable in the longitudinal direction together with the reactor. The second sealing portion fixes the reactor to the housing.

A filter element comprises a membrane layer; and a feed spacer on the membrane layer, wherein the feed spacer comprises a plurality of unit cells arranged in three dimensions, wherein each of the plurality of unit cells comprises a cavity defined by a triply periodic minimal surface, and wherein the cavities of the plurality of unit cells are interconnected to allow a fluid to pass through the cavities of the plurality of unit cells.

A filtration cell (10) for a biological sample having an outer housing (12) defining a first chamber and an inner housing (14) defining a second chamber is disclosed. The inner housing is disposed within the first chamber and rotatable with respect to the outer housing and at least a portion of the inner housing includes a filtration membrane (52). Upon rotation of the inner housing, a first portion of the biological sample passes from the first chamber into the second chamber and a second portion of the biological sample is restrained in the first chamber. Alternatively, the filtration cell may also include a rotation element disposed in the inner housing. Upon rotation of the rotation element with respect to the inner housing, a first portion of the biological sample to passes from the second chamber into the first chamber and a second portion of the biological sample is restrained in the second chamber.

The present disclosure provides a device for separating cells in fluid, comprising a first driving pump, a separation column, a detection column, a second driving pump, and several three-way valves and secondary driving pumps; one end of the separation column is connected with the first driving pump through a first three-way valve; the other end is connected with the second driving pump through a second three-way valve; the separation column includes at least five sub filtration columns in parallel; the sub filtration column comprises a fixing bracket and a track-etched membrane of polycarbonate or polyester material attached to the bottom of and the side surfaces all around the fixing bracket, wherein the pore diameter of the track-etched membrane is 5-25 m. The device of the present disclosure not only provides a new method for accurately determining whether there are circulating tumor cells in the blood of the living animal and provides a new method for sorting and counting the circulating tumor cells in the blood of the living animal, but also provides a pioneering new method and new device for therapy of the tumor transfer and removal of the tumor cells inside the body, and has extremely high economic and social values.

A zeolite membrane composite including a porous support and a zeolite membrane formed on a surface of the porous support. The zeolite membrane has an LTA-type crystal structure. The first atomic ratio: Si/Al of silicon element (Si) to aluminum element (Al) in the zeolite membrane is 1.29 or greater and 1.60 or less.

Composite polyether block amide (PEBA) copolymer tubes incorporate an ultra-thin PEBA layer that enables rapid moisture transfer and exchange through the tube. A composite PEBA film may include a porous scaffold support and may be formed or incorporated into the composite PEBA tube. A porous scaffold support may be coated or imbibed with PEBA to form a composite PEBA film. A composite PEBA film may be wrapped on a mandrel or over a porous scaffold support to form a composite PEBA tube. A film layer may be applied over a wrapped composite PEBA film to secure the layers together. The film layer by applied by dipping, spraying or painting.
