Graphene-Info: the graphene experts

Researchers from Washington University have designed a novel membrane technology that purifies water while preventing biofouling, or buildup of bacteria and other harmful microorganisms that reduce the flow of water. And they used graphene and bacteria to build these filtering membranes.

The team developed an ultrafiltration membrane using graphene oxide and bacterial nanocellulose that they found to be highly efficient, long-lasting and environmentally friendly. If their technique were to be scaled up to a large size, it could benefit many developing countries where clean water is scarce.

Gratomic has announced the development of new Graphene Ultra Fuel Efficient Tires (GUET) with certification and terrain testing targeted for completion in Q3, 2019. In March 2018, Gratomic announced that it is expecting to commercialize graphene-enhanced tires as a result of its advanced R&D program to include plasma-generated graphene in tires to increase their strength and reduce their.

"Purely from a demand perspective, we have been pulled into a market which represents a very large opportunity for Gratomic. Simply put, our customers want what we have; high quality graphene. Not only are Hybrid Graphene enhanced tires fuel efficient, but they can also demonstrate better handling and longer life" commented Gratomic's Chairman and Co-CEO Sheldon Inwentash. "The GUET tire market represents a very large vertical for Gratomic which the Company will be vigorously pursuing in 2019, and beyond".

Graphenest has launched two products, based on a proprietary graphene production method, now available to pre-order with a campaign price for a limited time.

The first product is HexaShield, a graphene-based paintable coating for RF electromagnetic interference (EMI) and radiation shielding. It reportedly provides drastic weight reduction, and reduced manufacturing cost as compared to metals, while achieving the required protection for the Gigahertz frequency range.

Zenyatta Ventures has announced that it has obtained TSX Venture Exchange approval and has changed its name from “Zenyatta Ventures Ltd.” to “ZEN Graphene Solutions Ltd.”. The name change reflects the Company’s decision to focus its development plans for the Albany Graphite Project on the graphene nano-material product opportunity.

The Company stated that the unique genesis and microcrystalline structure of the high-purity Albany Graphite mineralization gives ZEN a significant competitive advantage in producing mono-layer to few-layer graphene that is in the highest demand. The Company reported that it is presently assessing the various graphene conversion methods developed within its network of collaborative research partners with the goal of defining various scalable, low-cost, low-energy and environmentally friendly production methods.

Researchers at MIT have produced a catalog of the exact sizes and shapes of defects and holes that would most likely be observed (as opposed to the many more that are theoretically possible) when a given number of atoms is removed from the atomic lattice. The MIT team collaborated on this project with researchers at Lockheed Martin Space and Oxford University.

“It’s been a longstanding problem in the graphene field, what we call the isomer cataloging problem for nanopores,” Michael Strano from MIT says. "For those who want to use graphene or similar two-dimensional, sheet-like materials for applications including chemical separation or filtration", he says, “we just need to understand the kinds of atomic defects that can occur,” compared to the vastly larger number that are never seen".

Haydale has announced that it has signed a supply agreement to provide 76kg of its propriety piezoresistive ink to HP1 Technologies (HP1T) over an 18-month period. The value of the Supply Agreement was not disclosed.

HP1T creates bespoke flexible, printed, functionalized nano carbon-based sensor systems that can measure and collect high quality impact and pressure data. This newly signed supply agreement will see Haydale become HP1T's single supplier of functionalized nano carbon inks.
