Princeton researchers have dissipated some of the mystery around 'magic angle' graphene's superconductivity by showing an uncanny resemblance between it and the superconductivity of high temperature superconductors. Magic graphene may hold the key to unlocking new mechanisms of superconductivity, including high temperature superconductivity.

Ali Yazdani, Professor of Physics and Director of the Center for Complex Materials at Princeton University, led the research. He and his team have studied many different types of superconductors over the years and have recently turned their attention to magic bilayer graphene. Some have argued that magic bilayer graphene is actually an ordinary superconductor disguised in an extraordinary material, said Yazdani, but when we examined it microscopically it has many of the characteristics of high temperature cuprate superconductors. It is a déjà vu moment.

US-based CVD graphene developer General Graphene Corporation (GGC) has launched its new Gen3.0 CVD graphene production line. This 20-meters long roll-to-roll based system can produce single- and multi-layer graphene materials on copper films up to 400 mm wide.

GGC says that with the new line, its manufacturing capacity exceeds 100,000 m²/year. The company is now able to supply affordable and highly consistent CVD graphene in industrial volumes.

A few days ago, we published our quarterly update for our Graphene Supercapacitors Market Report. The update this time was comprehensive, as we overhauled the report.

The supercapacitors market is heating up (this is also true for other energy storage devices), as the world increases its investments in renewable energy and electric vehicles and transportation and supercapacitors play an ever more important role.

Reebok launched a new apparel collection, called Thermowarm+Graphene, that uses graphene to help retain heat. Reebok says that by printing graphene on the internal side of the clothing, it helps to retain between 8% and 15% more heat than areas without graphene (that depends on the base fabric the graphene is printed on).

The new collection includes hoodies, jackets and pants. The collection is now available globally on Reebok's online store, with prices ranging from $70 to $140 USD. Reebok plans to release more options in the collection in the future.

Graphwear, a startup developing graphene-based needle-free approaches to glucose monitoring, recently closed a $20.5 million Series B round. GraphWear is developing a skin-surface-level wearable made of graphene. The sensor is small, about the size of an Apple Watch — but the key piece of technology is actually housed on the bottom. It’s a thin slice of graphene that fits onto the back of the watch, or onto a sticker that can be worn on the abdomen.

This Series B round will be focused on helping the company build upon previous validation studies of the wearable, completing a pivotal trial and submitting for FDA clearance. The round was led by Mayfield, with participation from MissionBio Capital, Builders VC and VSC Ventures.

Researchers from The University of Manchester and Australia's Monash University have studied the effect of graphene functionalization on a vitrimer matrix (chemically crosslinked network able to undergo covalent bonds exchange reaction under a trigger). The chosen matrix was an epoxy vitrimer which, under heat, can exchange ester bonds, to be reprocessed, healed or relax stress while remaining covalently crosslinked. Existing work on vitrimer shows the aforementioned properties, so the team chose to focus on more unexploited properties of vitrimer for nanocomposites: their dissolution in an appropriate solvent to break the covalent bond under mild condition.

In the paper, the team shows that adding 4 kinds of graphene or functionalized graphene allows to tune some properties of the vitrimer matrix. After characterization, the epoxy is dissolved in ethylene glycol at 180C for 2h, the nanoparticles are subsequently separated and washed. The recovered nanoparticles are then free of any traces of epoxy, and intense characterization shows that despite some functionalization or unfunctionalization of graphene (depending of the initial graphene type used), the nanoparticles keep their core structure and could potentially be re-used in another matrix.

Directa Plus stated that a previously awarded contract for soil decontamination has now been reactivated for the company's subsidiary, Setcar. The contract, effective from October 2021, for a duration of 12 months, has a value to Setcar of approximately €900,000.

The project was previously halted as a result of an archaeological site being identified within the decontamination site.

At a recent conference, Ford Motor presented its innovative graphene-enhanced polyurethane (PU) foam that reduces noise in automobiles while also lowering their weight. The material was chosen as a finalist for the Polyurethane Innovation Award, given by the Center for the Polyurethanes Industry (CPI) during the conference. The foam is said to be used in all of Ford's North American vehicles.

One of the biggest challenges in developing the foam was dispersing a nanomaterial like graphene into a viscous polymer and keeping it from collapsing during mixing, said Alper Kiziltas, technical expert, sustainability and emerging materials at Ford.

Spain-based Graphenano is studying the use of graphene nanotechnology in dentistry. At the 2021 International Dental Show in Cologne, Graphenano Dental exhibited its products, such as the G-CAM disc for CAD/CAM milling systems, which relies on this technology.

Unlike zirconia, for example, which is still widely used, our graphene nano-reinforced biopolymer G-CAM disc has excellent blending properties, explained Graphenano Dental General Manager Jesús Martínez. He went on to say that the appearance is extremely natural and resolves all the mechanical, physico-chemical and biological failures of the rest of the materials currently used in the industry.
