Graphene-Info: the graphene experts

Holcim UK and Canary Wharf Group have completed a six-month collaboration focusing on next-generation, ultra low-carbon, and circular concrete mixes for upcoming development projects at Canary Wharf. The partnership – which included participation from several civil engineering consultancies and universities – tested novel formulations that aim to significantly reduce the carbon impact of construction materials.

One of the most promising developments from the trial program was a graphene-infused concrete mix, which achieved more than a 50% reduction in carbon footprint compared to traditional concrete, alongside enhanced strength and durability. The graphene component plays a key role in improving the mechanical performance and longevity of the concrete, enabling lower cement content and a smaller overall carbon footprint.

Researchers from Pohang University of Science and Technology, Griffith University and King Khalid University have developed a graphene-based nanofiltration system that can selectively extract lithium ions from magnesium‑rich brines using sunlight as the driving force. The approach combines edge‑functionalized graphene nanoribbons (GNRs) with photothermally reduced graphene oxide (PrGO), forming sub‑nanometer ion‑coordination channels that enable efficient lithium transport while rejecting competing ions such as magnesium.

Recovering lithium from natural brines is difficult because lithium typically exists at much lower concentrations than other dissolved salts. In South American salt‑flat brines, for example, magnesium concentrations can exceed lithium by ratios of 20:1 or higher. The challenge arises from the similar chemical behavior of the ions, even though their hydration energies differ significantly. Magnesium ions bind water molecules roughly four times more strongly than lithium ions. The new membrane exploits this difference by creating functionalized transport pathways that encourage lithium ions to partially shed their hydration shells and migrate through the membrane while magnesium remains strongly hydrated and effectively blocked.

Adisyn recently completed an initial proof-of-concept program demonstrating that graphene-enhanced composite materials can reduce radar reflection characteristics, with laboratory testing confirming up to 20dB reduction in radar reflection.

The program was conducted in collaboration with Ramot, the technology transfer company of Tel Aviv University. Composite samples were tested under controlled laboratory conditions and demonstrated up to 20dB reduction in radar reflection coefficient relative to baseline materials. The research team is now working on further optimization, targeting up to a 30dB reduction. According to Adisyn, a reduction of that magnitude would shrink the actual physical radar cross-section – the size of a target as detected by radar – by a factor of 1,000.

Argo Graphene Solutions has announced positive preliminary results from testing its graphene dispersion in cement-based materials.

The program evaluated a graphene-modified cement mixture for stucco scratch coat and 3D construction printing applications. Compared with standard cement formulations, the graphene-enhanced mixture showed better workability, adhesion, and consistency during application, without issues during mixing or placement. Argo reported that the graphene formulation produced a denser surface and improved bonding performance.

Vocxi Health, a medical technology company developing graphene-enhanced breath-based diagnostics, has partnered with Forj Medical to transform its MyBreathPrint device from a desktop prototype into a compact, handheld diagnostic platform designed for real-world use.

MyBreathPrint uses graphene-based nano sensors and machine learning based algorithms to detect volatile organic compounds (VOCs) produced by the body in a person’s breath that correspond with specific diseases, including lung cancer, the world’s leading cause of cancer death. The device’s ultra-sensitive sensors can detect compounds at parts-per-billion concentration, a thousand times more sensitive than conventional medical gas sensors. Combined with AI/ML based algorithm, the system delivers accurate, near-instant results in seconds, potentially enabling widespread screening in clinics, and ultimately, in homes.

Zentek recently announced the initiation of a pilot evaluation program with Quality Filters Inc., a U.S.-based manufacturer of heating, ventilation and air conditioning (“HVAC”) and industrial air filtration products, to assess the integration of Zentek’s proprietary air filtration media technology into Quality’s commercial product lines.

The pilot program is expected to span approximately 8 to 12 weeks and is designed to assess product compatibility, manufacturing scalability, and end-product performance under real-world commercial conditions. During the pilot period, the teams will collaborate on defining the commercial and technical framework for a potential long-term supply arrangement.
