University of Illinois team finds that defects in graphene membranes may improve biomolecule transport

Researchers at the University of Illinois examined how tiny defects in graphene membranes, formed during fabrication, could be used to improve molecule transport. They found that the defects make a big difference in how molecules move along a membrane surface. Instead...
Graphene may be the key to next-gen membranes that filter c02

Graphene may be the key to next-gen membranes that filter c02

A way to cut CO2 levels, produced from burning fossil fuels and released into the atmosphere, is through carbon capture, a chemical technique that removes CO2 from emissions (“postcombustion”). The captured CO2 can then be recycled or stored in gas or...
Graphene oxide layers made to mimic biological channels may clean up pharmaceuticals production

Graphene oxide layers made to mimic biological channels may clean up pharmaceuticals production

KAUST researchers have tailored the structure of graphene-oxide layers to mimic the shape of biological channels, creating ultra-thin membranes to rapidly separate chemical mixtures. This may have the potential to inspire new materials to clean up chemical and...

Chinese researchers achieve photo-induced ultrafast active ion transport through graphene oxide membranes

Researchers from the Chinese Tsinghua University and CAS demonstrated a coupled photon-electron-ion transport phenomenon through graphene oxide membranes. Using the energy of light, cations are able to move thermodynamically uphill over a broad range of...

Team finds that an electric field applied to a tiny hole in a graphene membrane could compress water molecules

Researchers at the University of Illinois at Urbana-Champaign have developed new theories regarding the compression of water under a high-gradient electric field. They found that a high electric field applied to a tiny hole in a graphene membrane would compress the...
