Applied Graphene Materials provides financial updates

AGM logo imageApplied Graphene Materials (AGM) recently gave financial updates, as part of which the Company stated it is looking forward to stronger sales growth and has enough cash to fund operations well into 2023 after a £5.5 million fundraise in January.

AGM said it continues to develop its dispersed GNP technology platform and the potential to extend this to adjacencies applicable to the coatings sector. AGM added that significant progress has been made with coatings customers, and it is now starting to see repeat business with some long-range engagements.

Archer Materials reports progress on graphene-based lab-on-chip fabrication capabilities

Archer Exploration logo imageIn November 2020, Archer Materials announced its plan to develop a graphene-based lab-on-chip device. Now, the Company provided an update on the progress it has achieved - it demonstrated that it can fabricate nanosize biosensor components of 100-150 nanometer features on silicon wafers.

In the past, prior to Archer utilizing local semiconductor foundry fabrication techniques, it was limited to one sensor per ~1 cm2. Now, with its in-house capability, it has miniaturized key biosensor components to chip-formats on silicon by nanofabrication translating to approx. over 1 million sensor components within a 1 cm2 area.

Researchers produce extremely conductive graphene-enhanced hydrogel for medical applications

An interdisciplinary research team of the Research Training Group (RTG) 2154 "Materials for Brain" at Kiel University (CAU) has developed a method to produce graphene-enhanced hydrogels with an excellent level of electrical conductivity. What makes this method special is that the mechanical properties of the hydrogels are largely retained. The material is said to have potential for medical functional implants, for example, and other medical applications.

"Graphene has outstanding electrical and mechanical properties and is also very light," says Dr. Fabian Schütt, junior group leader in the Research Training Group, thus emphasizing the advantages of the ultra-thin material, which consists of only one layer of carbon atoms. What makes this new method different is the amount of graphene used. "We are using significantly less graphene than previous studies, and as a result, the key properties of the hydrogel are retained," says Schütt about the current study, which he initiated.

Researchers find surprising electron interaction in ‘magic-angle’ graphene

A research team, led by Brown University physicists, has found a new way to precisely probe the nature of the superconducting state in magic-angle graphene. The technique enables researchers to manipulate the repulsive force - the Coulomb interaction - in the system. In their recent study, the researchers showed that magic-angle superconductivity grows more robust when Coulomb interaction is reduced, which could be an important piece of information in understanding how this superconductor works.

"This is the first time anyone has demonstrated that you can directly manipulate the strength of Coulomb interaction in a strongly correlated electronic system," said Jia Li, an assistant professor of physics at Brown and corresponding author of the research. "Superconductivity is driven by the interactions between electrons, so when we can manipulate that interaction, it tells us something really important about that system. In this case, demonstrating that weaker Coulomb interaction strengthens superconductivity provides an important new theoretical constraint on this system."
