Sparc Technologies has progressed construction of a modular and scalable manufacturing facility to produce graphene-based additives with commissioning expected in Q1 CY23.

The facility will enable the production of commercial quantities of graphene-based additives for the growing global coatings and composites markets, according to the Company's investor update.

G6 Materials Corporation announced its latest quarterly results for the quarter that ended on November 2022. Revenues increased to $490,527 (up from $320,204 last year) and net loss was $911,886, up from a net loss of $610,265 last year.

Gross profit, however, increased from $39,383 to $201,471 primarily due to a change in product sales mix. In July 2022, G6M announced the launch and immediate availability of the Breathe+ Pro Advanced Antimicrobial Graphene Air Filtration System.

Researchers from MIT, in collaboration with researchers from other Universities in the US and Korea, have used graphene (and hBN) to develop full-color vertically-stacked microLEDs  - that achieve the highest array density (5100 PPI) and the smallest size (4 µm) reported to date.

The researchers developed a 2D-materials based layer transfer (2DLT) technique - that involves growing the LEDs on 2D material-coated substrates, removing the LEDs, and then sttacking them. For the red LEDs, the researchers used graphene, coated on a GaAs wafer, while for the green and blue LEDs, they used hBN on sapphire wafers. The graphene red LEDs were transferred using remote epitaxy, while the hBN blue and green ones were removed using Van der Waals epitaxy.

Graphenano and the Institute of Molecular Science (ICMol) of the University of Valencia have developed a battery cell without current collectors or metal terminals, which uses graphene and carbon nanomaterials instead. The system enables the creation of safer, lighter and more efficient batteries for electric cars, aviation, stationary storage and more.

The scientists have succeeded in removing the copper, aluminium or steel sheets, the materials generally used in conventional batteries to evacuate the electric current generated. Simultaneously, the metallic tabs (current terminals), usually made of nickel or other metals, which are responsible for transferring the energy from the inside to the outside of the battery, have been eliminated. The replacement of these metals by graphene and other carbon nanomaterials significantly reduces the weight and volume of the devices. Furthermore, the team reported that tests have ascertained that this replacement increases the energy density by 30-60% and eliminates the risk of explosion or fire accidents on contact with air.

Haydale has announced that its bespoke mechanical graphene masterbatch has been used to create stronger and lighter composite sea kayaks for Norwegian paddle sport brand Norse Kayaks ("Norse").

Using the new graphene-enhanced material has reportedly made the Norse kayak 30% lighter, going from 23kg to 16kg, making the composite kayak easier to load and transport. The use of graphene in the vacuum infusion composite layup process has also increased both impact strength and stiffness, improving the resistance to breakage in critical areas of the kayak. Vibration dampening has also improved the user experience.
