Graphene-Info: the graphene experts

Researchers from Hefei University and Chinese Academy of Sciences (CAS) have developed a novel 3D-printed graphene/polymer double-layer composite featuring high anisotropic thermal conductivity that offers improved photothermal and electrothermal performance for advanced ice control applications. 

Graphene is known for its outstanding thermal and electrical conductivity, particularly its strong anisotropy—high in-plane conductivity and much lower through-plane conductivity. To capitalize on this property, the researchers used dual-nozzle fused deposition modeling (FDM) 3D printing to directionally align graphene within a thermoplastic polyurethane (TPU) matrix. The resulting double-layer composite, consisting of graphene-enhanced TPU (G-TPU) and neat TPU (N-TPU), achieved an in-plane thermal conductivity of 4.54 W/(m·K), with an anisotropic ratio of about 8.

HydroGraph Clean Power announced that it has raised over $2.2 million CAD (around $1.6 million USD) through the recent exercise of warrants. The company says that this fund raising will support its accelerated production scale-up efforts in response to growing commercial demand.

HydroGraph recently announced new testing results demonstrating the performance benefits of its Fractal Graphene™ (FGA-1) as an additive in polyurethane (PU) coatings. Earlier this year the company, together with NEI Corporation, announced the launch of NANOMYTE® FGA-1AD and NANOMYTE® FGA-1ND, a new line of advanced graphene dispersions.

British climate tech company Levidian and Canadian graphene technology company Zentek have entered an agreement to explore the establishment of a new manufacturing facility in the Middle East.  

The companies have agreed to combine their expertise in carbon capture, graphene production and materials development to accelerate the roll out of Zentek’s ZenGUARD™ Enhanced Air Filters and other graphene-enhanced products within the region, while also supporting the production of graphene for other industries.  

Haydale Graphene Industries has announced the conclusion of the auction process for its subsidiary, Haydale Ceramic Technologies LLC, which was placed into Chapter 11 bankruptcy to stop cash flow drain and maximize shareholder value. 

Despite initial interest, geopolitical tensions and trade issues affected the auction, resulting in a sale to Greenleaf Corporation for approximately $680,000. The outcome aligns with Haydale’s strategy to reduce overhead costs and improve profitability, ensuring the protection of its core business.

Researchers from Fudan University in China have used graphene to create the world’s fastest flash memory, which performs about 25 billion operations per second.

The device, called "PoX", takes 400 picoseconds (0.0000000004 sec) to store one bit of information. Usually, traditional static and dynamic RAM (SRAM, DRAM) records data at a speed of 1 to 10 nanoseconds, but does not retain information in the event of a sudden power outage. Flash drives don’t need a power source to store data, but they take micro and milliseconds to store, which is too slow for modern artificial intelligence accelerators that send terabytes of data in real time.

Zentek has announced the completion of the Innovative Solutions Canada - Testing Stream contract for ZenARMOR™ nano-pigment in military grade, chromate-free corrosion protection aerospace paint systems, and a new collaboration with Jazeera Paints Company for continued product development and testing.

ZenARMOR™ was evaluated in commercial non-chromate aviation paint systems developed by PPG and Akzo Nobel. Three rounds of corrosion testing were completed from September 2023 to July 2024 and testing followed ASTM B117 (salt spray) and ASTM D5894 (cyclical corrosion) standards. The tests were reportedly successful in demonstrating the effectiveness of ZenARMOR™ nano-pigments in inhibiting corrosion of the aluminum alloy AA2024-T3.

United Utilities has joined forces with climate tech company Levidian to demonstrate the potential of using biogas produced from wastewater to create hydrogen and graphene at its wastewater treatment works.

The trial is taking place at Manchester Bioresources Centre, part of Davyhulme Wastewater Treatment Works, where modern-day sewage treatment processes were initially developed back in 1914. Levidian’s LOOP device uses electromagnetic waves to split methane gas into hydrogen and carbon, capturing the carbon in solid form as graphene. The lower carbon blend gas is then fed into United Utilities’ onsite generator where it is burned to help power the site.
