Scientists at EPFL have developed a scalable method to produce porous graphene membranes that efficiently separate carbon ...

This concentration is in turn controlled by the type and concentration of the carbonaceous gas, and the thickness of the nickel layer. After a chemical etching of the nickel, the graphene membrane ...

Holey graphene might be used as a membrane for advanced types of gas separation, removing impurities from natural gas, capturing carbon from flue gases, or producing hydrogen for fuel. By the same ...

Graphene is the world’s first two-dimensional material, flexible, transparent, more conductive than copper, and is known to block the passage of helium, the hardest gas to block. Corrosion costs the ...
