- New process turns ordinary marker ink into graphene
Researchers from Graz University of Technology, University of Florence, Istituto Italiano di Tecnologia and Scuola Superiore Sant'Anna have demonstrated an innovative process that enables certain common dyes - found in standard marker pens - to be converted into laser-induced graphene (LIG). The study focused on Eosin Y, a widely used xanthene dye, which exhibited excellent stability and structural properties ideal for laser conversion. While most existing LIG production relies on polymer precursors such as polyimide, this research shows that non-polymeric materials like dyes and inks can also serve as effective precursors.

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 puts US unit into bankruptcy, seeks to sell and focus on UK graphene-related business
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 develop new technique to directly measure energy gaps and bandwidths in multilayer graphene systems
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.

- New smart sensor takes the pain out of wound monitoring
A major challenge in self-powered wearable sensors for health care monitoring is distinguishing different signals when they occur at the same time. Researchers addressed this issue by uncovering a new property of a sensor material, enabling the team to develop a new type of flexible sensor that can accurately measure both temperature and physical strain simultaneously but separately to more precisely pinpoint various signals.
- Paragraf and University of Cambridge awarded Innovate UK grant for graphene memory device project
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 measure superfluid stiffness of magic-angle twisted bilayer graphene
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.
- 2D-EPL project reports results of two multi-project wafer runs
Researchers from AMO, Graphenea and RWTH Aachen University have, as part of the European experimental pilot line for electronic and optoelectronic devices based on graphene and related two-dimensional (2D) materials, namely the Experimental Pilot Line (2D-EPL) project, reported the results obtained during the first and third multi-project wafer (MPW) runs completed at the end of 2022 (MPW run 1) and 2023 (MPW run 3).

- New structures of a critical amyloid protein illuminated
The tiny protein known as transthyretin can cause big problems in the body when it misfolds after secretion. While healthy transthyretin moves hormones through blood and spinal fluid, misfolded versions of the protein form dangerous clumps in the heart and along nerves -- triggering a progressive and fatal disease known as transthyretin amyloidosis (ATTR). Up to a quarter of all men over the age of 80 have some degree of ATTR, which can cause shortness of breath, dizziness and tingling or loss of sensation in the extremities. Now, scientists have uncovered new structures of transthyretin.
