Researchers at the Chinese Academy of Sciences (CAS) and Shandong University of Technology have developed a new graphene oxide-based sensor design that, through machine learning, was able to develop a near-human sense of taste. This device is uniquely able to operate in a moist environment, better approximating the conditions inside the human mouth. Image from: PNASThe sensor was made of multiple layers of graphene oxide enclosed in a nanofluidic device. Graphene oxide is known to change its electrical conductivity when exposed to different chemicals. The researchers used this property to measure electrical variations in the sensor when it was exposed to a sampling of 160 chemicals, each associated with a unique flavor profile. Using these data, a machine-learning algorithm was able to create a 'memory' of flavors.

Researchers at the University of Illinois have pulled off a laser first: they built a new kind of eye-safe laser that works at room temperature, using a buried layer of glass-like material instead of the usual air holes. This design not only boosts laser performance but also opens the door to safer and more precise uses in defense, autonomous vehicles, and advanced sensors. It’s a breakthrough in how we build and power lasers—and it might change what lasers can do in the real world.

Scientists have discovered a revolutionary new method for creating quantum states by twisting materials at the M-point, revealing exotic phenomena previously out of reach. This new direction dramatically expands the moiré toolkit and may soon lead to the experimental realization of long-sought quantum spin liquids.

Graphmatech has secured a €2.5 million (around USD$2.9 million) EU grantto construct a pilot facility at its Uppsala base, aimed at scaling its polymer-graphene hydrogen storage lining technology, aiming to reduce hydrogen leakage by 83%. The project, supported by the Swedish Energy Agency, will scale production from 5 to 200 tonnes annually and enable industrial testing, with plans to deploy the technology in 1,500 commercial vehicles by 2027.The new Uppsala facility will house a production line, boosting Graphmatech’s output from 5 to 200 tonnes annually, enabling large-scale industrial testing of its cutting-edge materials.

Graphene Innovations Manchester (GIM), a UK-based deep-tech company, has launched GIM WildCat, a new commercial development and investor engagement center at Sharjah Research, Technology & Innovation Park (SRTI Park), aimed at accelerating the commercialization of graphene-based technologies in the Middle East.GIM said its goal is to showcase advanced graphene-based products, build investor and partner networks, expand across the Middle East and North Africa (MENA) and Asia, and drive joint research and development within the park’s innovation ecosystem.

Argo Graphene Solutions has announced the opening of its Gulf Coast Distribution and Mixing Center in Kenner, Louisiana, a strategically located suburb of New Orleans and key hub in its North American growth plan. Positioned near the Port of New Orleans, the Kenner facility provides direct access to 14,500 miles of inland waterways, six Class I railroads and major east-west transit via Interstate 10.Argo has negotiated an agreement with Landry Construction of Kenner, Louisiana, to oversee storage, mixing and distribution of Argo’s new graphene infused concrete and cement. This initial facility will provide a launch point to fine-tune product and service Landry’s existing and new client base.

Graphene Manufacturing Group (GMG) has commenced global sales of its G® Lubricant product across several global markets, including Australia, the UK, Europe, China, Canada, and the US. The product will be available through both GMG's website and direct-to-customer channels.GMG is exploring partnerships with large oil and gas companies and OEMs, while actively promoting the product through various advertising campaigns. The company also noted it has received formal requests for distribution rights in additional countries and is working to finalize packaging and labelling updates to comply with local requirements. It is scaling its sales team and production capabilities to meet growing demand, indicating a strategic push to solidify its position in the lubricant market.

Scientists have finally uncovered a quantum counterpart to Carnot’s famed second law, showing that entanglement—once thought stubbornly irreversible—can be shuffled back and forth without loss if you plug in a clever “entanglement battery.”

Researchers at Soochow University, University of Science and Technology of China, Peking University, ShanghaiTech University, Beijing Graphene Institute and additional collaborators have developed a copper-based growth process that produces large-area trilayer graphene films with uniform thickness and improved mechanical strength.

Image from: Nature CommunicationsThe team stated that much of graphene's functional promise - especially in electronics and optoelectronics - relies not on the single-layer form that dominates laboratory work, but on precise multilayer structures. Adding layers enables electronic band structures to be tuned and improves properties such as stiffness and thermal transport. Despite this, the controlled synthesis of multilayer graphene films with consistent thickness across large areas has remained quite elusive.

Levidian has announced a new partnership with graphene R&D firm planarTECH to accelerate graphene adoption in Asia.The planarTECH team already has a manufacturing base and established network of customers and research partners in region and will be launching Levidian’s LOOP technology to the Asian market at the ‘Nano Korea 2025’ 2D Materials Seminar in Ilsan, South Korea.

Versarien has announced that it has extended its existing manufacturing license agreement, and know-how license and technical assistance agreement, with Montana Química LTDA, initially announced in March 2024.  The extended agreements cover the use of the Company’s proprietary graphene and related material thermoplastic compounds and masterbatches (Polygrene™) in products to be manufactured and sold by Montana in South America, together with Versarien providing further additional know-how, technical assistance and training to Montana.

A precious metal used everywhere from car exhaust systems to fuel cells, platinum is an incredibly efficient catalyst—but it's costly and carbon-intensive. Now, a serendipitous collaboration between scientists at ETH Zurich and other European institutions has opened a new frontier in understanding and optimizing platinum-based catalysts at the atomic level.

First Graphene (ASX:FGR) has updated that it is progressing on its HyPStore Project, reportedly valued at $3.72 million, aimed at developing advanced hydrogen storage tanks. Testing is now underway at the company’s research and development laboratory in Manchester, UK. The project seeks to commercialize lightweight, impermeable cryogenic tanks designed for the safe storage and transportation of liquid hydrogen, which offers higher energy density and easier handling compared to gaseous hydrogen. The Company has commenced testing graphene materials provided by Australia Sunlight Group to create a graphene-enhanced resin system. These materials will be evaluated against First Graphene’s PureGRAPH material. Incorporating graphene nanoplatelets into resin aims to create an impermeable tank by forming a protective barrier, which has previously demonstrated a reduction in hydrogen permeability by up to 48 times. The Tinius Olsen Universal Tester will measure material performance through various tests, including tensile, compressive, and flexural strength assessments.

Researchers have achieved a major breakthrough by generating quantum spin currents in graphene—without relying on bulky magnetic fields. By pairing graphene with a magnetic material, they unlocked a powerful quantum effect that allows electrons to carry information through their spins alone. This discovery could spark a new era of faster, more energy-efficient spin-based technologies.
