Graphene applications: what is graphene used for? - Page 30

Zhejiang Textile New Material Technology, located in Zhuji, Zhejiang, China, is currently testing its new graphene-enhanced antibacterial socks. The Company explained that the socks are first manufactured in a traditional way, then treated with a graphene antibacterial multifunctional finishing agent.

The Company stated that rigorous tests are currently being performed to see if the required effects are achieved. The team explained that generally, most countries require that the antibacterial effect should reach more than 70%. Zhejiang Textile New Material Technology’s socks reportedly reach more than 90%.

SoundCell, a spin-off of TU Delft, has secured funding of €350,000 from proof-of-concept fund UNIIQ, together with Delft Enterprises. The funds will go towards facilitating the development of its graphene technology for single cell resolution antibiotic sensitivity testing.

SoundCell develops innovative technology that can measure the vibrations produced by living bacteria. This technology makes use of graphene membranes and could have significant implications for the detection and prevention of antibiotic resistance, as it would enable patients to receive effective medication against bacterial infections faster than today’s standard.

Graphene Manufacturing Group (GMG) has announced the receipt of regulatory and local council approvals for the commercial scale manufacturing of batteries at its existing Richlands site in Brisbane, Australia. To date GMG has been adhering to a research and development regulatory approval to make battery cell prototypes. In addition, this site already has council approvals that allow GMG to manufacture its graphene.

These regulatory approvals are seen an important step in GMG’s consideration at an appropriate future time to build and operate a battery manufacturing plant at the GMG Headquarters at Richlands.

Paragraf has announced a second manufacturing site in Huntingdon, Cambridgeshire, UK.    

The new site will allow Paragraf to massively increase the size of its clean room facilities and other manufacturing areas while providing additional office space. The Company plans for its staff to begin to move in during the first quarter of 2023 and production is expected to ramp up in the second half of the year. The initial expansion of staff into the Huntingdon facility will enable accelerated development of the research, development and production areas on the current Somersham site to cope with increasing customer demand as fit out of operations at the new site progresses.

Haydale has announced it has supplied audio equipment manufacturer Rega Research ("Rega") with its mechanically enhanced prepreg for improved sound quality on its latest turntable.

Using Haydale's HDPlas technology, the graphene-enhanced prepreg has been applied into the manufacturing process for Rega's award-winning turntables. The mechanically enhanced prepreg has been combined into the stressed skin design of the plinth and bonded to the core material to increase the stiffness of the part by 11% reducing resonance and improving sound quality.

Researchers from Ohio State University, The University of Texas at Dallas and Japan's National Institute for Materials Science have reported new evidence of how graphene, when twisted to a precise angle, can become a superconductor, moving electricity with no loss of energy.

The team announced their finding of the key role that quantum geometry plays in allowing this twisted graphene to become a superconductor.

Graphene Layers, a start-up that develops graphene-based solutions, and Rutgers EcoComplex “Clean Energy Innovation Center” and its WindIgnite “Offshore Wind Supply Chain Accelerator Program,” announced a partnership aimed at advancing their shared goals and objectives in the fields of clean energy generation, sustainable development, and integrating graphene technology for Offshore Wind (OSW) applications. 

The partnership will focus on developing and commercializing graphene-based solutions that contribute to sustainable OSW supply chain development and help tackle some of the world’s most pressing environmental and societal challenges.

Researchers from Carnegie Mellon University and MIT have demonstrated a 3D graphene-nanowire “sandwich” thermal interface that enables an ultralow thermal resistance of ∼0.24 mm2·K/W that is about 1 order of magnitude smaller than those of solders and several orders of magnitude lower than those of thermal greases, gels, and epoxies.

In addition, the new 3D graphene-nanowire “sandwich” thermal interface also boasts a low elastic and shear moduli of ∼1 MPa like polymers and foams. It exhibits excellent long-term reliability with >1000 cycles over a broad temperature range from −55 °C to 125 °C. This nanostructured thermal interface material can greatly benefit a variety of electronic systems and devices by allowing them to operate at lower temperatures or at the same temperature but with higher performance and higher power density.

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.
