Graphene-Info: the graphene experts

Researchers from the University of Calgary, University of British Columbia, University of Waterloo and Aalto University recently developed an all-graphene water-based ink for 3D printing via direct ink writing, which the team considers first of its kind. The ink could unlock new possibilities for addressing environmental challenges, such as eliminating invisible electromagnetic pollution from our surroundings.

The eco-friendly graphene ink enables applications in various fields, including electromagnetic interference (EMI) shielding, electronics, and environmental protection while providing a scalable solution for next-generation 3D-printed technologies.

Haydale Graphene has reportedly announced that it has initiated a corporate insolvency process for its US subsidiary Haydale Ceramic Technologies (HCT) under chapter 11 of the US Bankruptcy Code. The company said it had filed the necessary documents in the state of Georgia, with a court hearing expected in the coming days to formalize the proceedings.

As part of the process, Haydale said it planned to sell HCT's assets through a court-supervised public auction, as it said it saw that as the best route to maximize asset value and recover cash for the parent company, which has a £12.8 million intercompany debtor balance tied to its US operations. While several third-party firms had expressed interest in acquiring HCT's assets, there was no guarantee of financial recovery.

Researchers at the Swiss École Polytechnique Fédérale de Lausanne (EPFL) and National Institute for Materials Science in Japan have developed a new technique to directly measure energy gaps and bandwidths in multilayer graphene systems, paving the way for deeper insights into exotic quantum states and future electronic devices.

When layers of graphene are stacked on top of each other and slightly rotated, the atomic lattices create a periodic interference pattern known as a moiré pattern. This pattern significantly changes the electronic behavior of the material, sometimes leading to exotic quantum phenomena like superconductivity and magnetism. However, directly probing the fine details of these quantum states has been a challenge. Understanding how electrons behave in these stacked graphene systems is crucial for designing future electronic and quantum devices. But conventional techniques struggle to precisely measure energy gaps and bandwidth—the parameters that dictate how electrons move and interact in these systems. Without a reliable method to extract this data, researchers have been piecing together the puzzle through indirect observations.

SCALE Nanotech, an advanced R&D company based in Estonia, has announced the launch of its spinout Dragon Elements in Spain, aiming to enter into the XR and wearable electronics sector. Dragon Elements is set to commercialize LATIDO® capsules, a graphene-based technology designed to "redefine human interaction with hardware by eliminating the need for traditional audio and video components", as per the Company.

LATIDO® aims to mark a "radical shift in audiovisual hardware". Unlike conventional technology that requires separate components for sound and vision, LATIDO® harnesses millions of graphene membranes to seamlessly control both light and sound within a single monolithic device, removing the need for separate screens or speakers.

NanoXplore has reported its financial results for the three-month and six-month periods ended December 31, 2024, citing total revenues of CAD$33,120,886  (around USD$23,165,000) in Q2-2025 compared to $29,063,024 (around USD$20,300,000) in Q2-2024, representing a 14% increase. 

Loss stood at CAD$2,894,922 (about USD$2,000,000) in Q2-2025 compared to $2,428,388 (about USD$1,700,000) in Q2-2024 and total long-term debt of $5,452,604 (almost USD$3,800,000) at December 31, 2024, down by $893,899 (USD$625,000) compared to June 30, 2024.

Paragraf, the UK-based company pioneering the mass production of graphene-based electronics with standard semiconductor processes, has been awarded a grant of £419,419 (around USD$520,000) from Innovate UK for the purpose of producing a proof-of-concept prototype of a novel semiconductor memory technology using a new class of ferroelectric materials complemented with graphene on a silicon platform.

The joint grant will also see Prof. Judith Driscoll’s research group at the University of Cambridge’s Department of Materials Science and Metallurgy receive £299,198 to develop processes for depositing ferroelectric materials on top of Paragraf’s transfer-free graphene in order to produce novel memory devices, including a graphene-ferroelectric field effect transistor (G-FeFET). This is expected to lead to power savings of an order of magnitude relative to existing memory device technology, which is key to saving power in data centres and consumer devices to support the AI revolution.

Researchers from MIT and Japan's National Institute for Materials Science have directly measured superfluid stiffness for the first time in “magic-angle” graphene — two or more atomically thin sheets of graphene twisted with respect to each other at just the right angle to enable a host of exceptional properties, including unconventional superconductivity. The term “superfluid stiffness,” or the ease with which a current of electron pairs can flow, is a key measure of a material’s superconductivity.

This superconductivity makes magic-angle graphene a promising building block for future quantum-computing devices, but exactly how the material superconducts is not well-understood. Knowing the material’s superfluid stiffness will help scientists identify the mechanism of superconductivity in magic-angle graphene. The team’s measurements suggest that magic-angle graphene’s superconductivity is primarily governed by quantum geometry, which refers to the conceptual “shape” of quantum states that can exist in a given material.
