The present invention provides a separation membrane that is suitable for separating an acid gas from a gas mixture containing the acid gas and has a high acid gas permeability. A separation membrane (10) of the present invention includes: a separation functional layer (1); a porous support member (3) supporting the separation functional layer (1); and an intermediate layer (2) disposed between the separation functional layer (1) and the porous support member (3), and including a matrix (4) and nanoparticles (5) dispersed in the matrix (4).

The present disclosure relates to systems and methods for electrically conductive membrane separation from a mixture solution via membrane nanofiltration, electro-filtration, or electro-extraction by: generating an electric field at the membrane filter, holding the membrane filter at a constant electric potential, or driving a constant current through the membrane filter; feeding a mixture solution through the membrane nanofiltration system; and separating a component from the mixture solution into a permeate solution.

Disclosed herein are asymmetric multilayer carbon molecular sieve (CMS) hollow fiber membranes and processes for preparing the membranes. The processes include simultaneously extruding a core dope containing a polymer and suitable nanoparticles, a sheath dope, and a bore fluid, followed by pyrolysis of the extruded fiber.

A solid type nano-pore sequencer is arrayed easily. In a liquid column separation device including first and second base materials, a liquid feeding unit supplies fluids to a gap between the two base materials. Hydrophilic and hydrophobic regions are disposed on a surface of the second base material, and the hydrophilic region is disposed to oppose a predetermined position of the first base material where a substance to be measured is made to pass through. Also, a flow passage space includes at least one inlet and outlet through which fluids can flow in and out. A representative length of the hydrophilic region is made larger than a distance between the first and second base materials, and thereby a liquid column capable of connecting the first base material and the second base material is formed by making two or more immiscible fluids to flow by the liquid feed unit.

A porous composite includes a porous base material and a porous collection layer provided on a collection surface of the base material. The collection layer includes particles deposited in pores of the collection surface. In a plan view of the collection surface, the proportion of the area of a covered region that is covered with the collection layer out of the collection surface is less than or equal to 70%, and the proportion of the area of a pore region out of a non-covered region that is not covered with the collection layer is less than or equal to 15%.

Methods for forming porous or nanoporous semiconductor materials are described. The methods allow for the formation of arrays pores or nanopores in semiconductor materials with advantageous pore size, spacing, pore volume, material thickness, and other aspects. Porous and nanoporous materials also are provided.

The objective of the present invention is to provide a hydrogen-releasing film, a composite hydrogen-releasing film and a hydrogen-releasing laminated film that are not prone to embrittlement in the usage environmental temperatures of electrochemical elements. The hydrogen-releasing film containing an alloy, wherein the alloy is a PdAu alloy, and the Au content in the PdAu alloy is 15 mol % or more.

Disclosed herein are porous asymmetric silicon membranes. The membranes are characterized by high structural stability, and as such are useful as anode components in lithium ion batteries.

Provided is an oligosilane production method with which a target oligosilane can be selectively produced. A reaction-produced mixture fluid which contains an oligosilane obtained by the dehydrogenative coupling of a hydrosilane is supplied to a membrane separator under specific conditions and/or brought into contact with an adsorbent under specific conditions.

The present technology provides micro fabricated filtration devices, methods of making such devices, and uses for microfabricated filtration devices. The devices may allow diffusion to occur between two fluids with improved transport resistance characteristics as compared to conventional filtration devices. The devices may include a compound structure that includes a porous membrane overlying a support structure. The support structure may define a cavity and a plurality of recesses formed in a way that can allow modified convective flow of a first fluid to provide improved diffusive transport between the first fluid and a second fluid through the membrane.
