Microfabricated regular sieving structures hold great promise as an alternative to gels to improve the speed and resolution of biomolecule separation. In contrast to disordered porous gel networks, ...

(Nanowerk Spotlight) The petrochemical industry relies on separating chemicals that differ by just fractions of a nanometer in size. Methanol must be purified from similarly-sized molecules in the ...

A new MIT microchip system promises to speed up the separation and sorting of biomolecules such as proteins. The work is important because it could help scientists better detect certain molecules, or ...

(Nanowerk News) Classical molecular sieve membranes, with 3D microparticles and 2D nanosheets as primary building blocks, are promising in chemical separation. Separation within such membranes relies ...

Scientists continue to explore the potential of graphene, aka the one-atom thin sheet of bonded carbon atoms that was created more than a decade ago after researchers first peeled a few layers off a ...

An international team of researchers, affiliated with UNIST has presented a novel hydrogen isotope separation system based on a porous metal organic framework (MOF). The isolation of deuterium from a ...

If a pore size in a membrane is comparable to the size of atoms and molecules, they can either pass through the membrane or be rejected, allowing separation of gases according to their molecular ...

Researchers at University of New South Wales have reported details about a novel sieving-aids technology that improves the separation of metal fragments from other components when recycling ...
