Watercycle Technologies secures funding for its graphene-based membrane tech

Watercycle Technologies, a spin-out company from The University of Manchester, has secured initial funding for its technology that uses graphene-based membranes and systems to extract lithium and other minerals from brines and water solutions.

Led by Sebastian Leaper, a former PhD student from the Department of Materials at Manchester, Watercycle Technologies has taken Tier 2 membership of the Graphene Engineering Innovation Centre (GEIC), with lab space and access to advanced 2D materials facilities and expertise in prototyping.

China-based researchers design new method to pre-enrich uranium in seawater using graphene oxide

Researchers at the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS), in collaboration with teams from China's Lanzhou University and Hebei University, have developed a graphene oxide-based method of pre-enriching uranium in seawater by membrane filtration.

GO to help enrich Uranium in seawater image

In their study, the scientists fabricated a new type of glycine cross-linked composite graphene oxide (GO-Gly) membrane with good ion sieving properties, which can meet the demands of uranium pre-enrichment in seawater.

Graphene helps track the nanomotion of bacteria

A team of researchers from TU Delft, led by dr. Farbod Alijani, recently managed to capture the low-level noise of a single bacterium using graphene.

Being able to pick up on the miniscule sounds of bacteria can help track if an antibiotics is working, or if the bacteria are resistant to the antibiotic. Alijani's team was originally looking into the fundamentals of the mechanics of graphene, but at a certain point they wondered what would happen if it comes into contact with a single biological object.

NematiQ announces commercial-scale graphene membrane milestone achievement

NematiQ, an Australia-based developer of graphene oxide (GO) membranes for water treatment applications, has reported commercial-scale manufacture of an innovative graphene membrane.

Over the last five years, NematiQ has developed a patented, layer-by-layer methodology to produce the graphene membrane. NematiQ has achieved a milestone by producing more than 1,000 meters worth of 1,000-millimetre-wide flat sheet graphene membrane, at speed, on an industrial roll-to-roll coating machine, showcasing its ability to manufacture graphene membrane at a commercial scale.

Researchers achieve precision sieving of gases through atomic pores in graphene

A team of researchers, led by Professor Sir Andre Geim at The University of Manchester, in collaboration with scientists from Belgium and China, used low-energy electrons to make individual atomic-scale holes in suspended graphene. The holes came in sizes down to about two angstroms, smaller than even the smallest atoms like helium and hydrogen.

Exponentially selective molecular sieving through angstrom pores image

The researchers report that they achieved practically perfect selectivity (better than 99.9%) for such gases as helium or hydrogen with respect to nitrogen, methane or xenon. Also, air molecules (oxygen and nitrogen) pass through the pores easily relative to carbon dioxide, which is >95% captured.
