An object of the present invention is to suppress a defect in a carbon membrane for fluid separation use with a dense carbon layer formed on a porous carbon support. The present invention is a carbon membrane for fluid separation use, including a dense carbon layer formed on a porous carbon support, wherein X<Y when the ratio of the content of silicon atoms to the total content of carbon atoms and silicon atoms at the center position in the membrane thickness direction of the porous carbon support is X (atomic %), and the ratio of the content of silicon atoms to the total content of carbon atoms and silicon atoms at the position of 3 μm from the interface between the porous carbon support and the dense carbon layer to the porous carbon support side is Y (atomic %).

A device for filtration or extraction using at least one filtration membrane is disclosed. The device is shaped like a Buchner funnel, but small enough to fit with wide bore pipette tips, slip tip syringes or an adaptor of a robotic liquid handler or pipettor. It also houses one or more filtration membranes and or a separation resin. A reservoir adaptor can be added to the top in a fluid tight manner to provide a removable large volume container where needed for larger samples, and a gasket adaptor allows the reservoir to be connected to other devices in a fluid tight manner.

The present disclosure provides advantageous porous assemblies, and improved systems and methods for utilizing and/or fabricating the porous assemblies. More particularly, the present disclosure provides porous assemblies fabricated at least in part by additive manufacturing (e.g., via a 3D printing process, such as, for example, via an electron beam additive manufacturing process, via a laser additive manufacturing technology, via an inkjet or a binder jet additive manufacturing process, etc.), the porous assemblies including a porous monolith support structure or substrate for a sensitive or active layer of a multi-layer application (e.g., for sensitive/active layers in fuel cell/electrolyzer/battery and other multi-layer applications).

A membrane comprising a crystalline material deposited on a porous support. The crystalline material is made of tectosilicate with a portion of the Si atoms substituted with metal atoms. The membrane is useful in the separation of oil and water.

A zeolite membrane composite includes a porous support and a zeolite membrane formed on the support. The zeolite membrane includes a low-density layer that covers the support, and a compact layer that covers the low-density layer. The compact layer has a higher content of a zeolite crystalline phase than the low-density layer. By in this way forming the compact layer on the low-density layer that covers the support, the thin compact layer with no defects can be formed more easily than in the case where a compact layer is formed directly on a support.
