Graphene-Info: the graphene experts

Graphene Manufacturing Group (GMG) has announced a global exclusive Memorandum of Understanding (MOU) with Alstom for testing and developing graphene products for the rail industry – specifically for Heating, Ventilation, Air Conditioning (HVAC) systems.

Craig Nicol, CEO & Managing Director of the Company, commented “We are thrilled to be partnering with Alstom, one of the world’s most recognized names in rail and transportation. This global exclusive MOU gives GMG the opportunity to bring our graphene technology into one of the largest and most technically demanding sectors in the world. Rail systems demand the highest standards of performance, durability and efficiency - and we believe graphene is uniquely positioned to deliver meaningful improvements across a range of applications. We look forward to working closely with the Alstom team to develop and commercialize graphene products that will help shape the future of rail.”

Graphene Leaders Canada (GLC), a Canadian advanced materials company, has announced the commercialization of its proprietary graphene-enhanced electroless nickel (EN) additive, marking a milestone in the Company's transition from research and development to commercial deployment. 

Following years of scientific innovation, engineering, formulation optimization, and industry validation, GLC has brought its graphene nanoplatelets (GNPs) additive technology from the laboratory to real-world industrial applications, reporting significant improvements in corrosion resistance and wear performance over conventional electroless nickel coatings.

Researchers from Hebei GEO University and Shijiazhuang Tiedao University in China have developed a flexible optoelectronic memristor based on a composite of graphene oxide (GO) and perovskite quantum dots, designed to sense and process images in dimly lit conditions. 

Memristors are seen as a key building block for flexible neuromorphic vision systems. Because they can rapidly tune their resistance in response to optoelectronic inputs, they emulate the way biological synapses adjust signal weights - the behavior needed for artificial retina-like sensors that sense and compute in the same place, rather than shuttling data to a separate processor. The team, led by Jingjuan Wang and Lingzhi Tang of Hebei GEO University's College of Information Engineering, combined GO sheets with perovskite quantum dots to create a switching layer whose behavior changes markedly between dark and illuminated conditions.

Aromaticroot Queen Farmer Products LLP, a company based in Tamil Nadu, India, has announced that it is seeking investment to build what it describes as the world's first vetiver-to-graphene production facility. The company reports that it has completed the project's validation stage and is now at the fundraising phase.

Vetiver is a perennial grass cultivated widely in India, mainly for the aromatic oil extracted from its roots. The company's stated concept is to use vetiver biomass as the carbon feedstock for graphene production, sourced through a network of more than 3,600 contracted farmers under what it describes as a traceable procurement model. It presents the project as a climate-tech venture linking agriculture to advanced materials manufacturing, citing ESG, rural livelihood, and circular-economy benefits alongside the materials themselves.

University of Arizona researchers have demonstrated that atomically precise graphene nanoribbons (GNRs) can function as highly sensitive gamma-radiation sensors, while maintaining their underlying structural integrity under exposure - an unusual combination that could be valuable for fusion energy systems and space electronics.

In a proof-of-concept study, the team fabricated field-effect transistors (FETs) based on nine-atom-wide armchair graphene nanoribbons (9-AGNRs), synthesized using a bottom-up, on-surface approach. The resulting structures were one atom thick and approximately 45 nanometers long on average, placing them in the quasi-one-dimensional regime where quantum transport effects dominate. These devices were characterized before and after gamma irradiation using Raman spectroscopy and electrical transport measurements.

Argo Graphene Solutions has reported encouraging initial performance results from its graphene oxide (GO) cement additive program, using graphene produced through the proprietary STREAM™ graphene production platform licensed exclusively from Grapherry. 

In its initial testing, Argo found that adding only 0.05 wt.% graphene oxide - roughly five parts GO per 10,000 parts cement by weight - increased ultimate compressive strength by approximately 60% compared to control samples. Testing used ASTM-standard 2-inch by 2-inch cement specimens cured for seven days prior to compression testing, and the Company reports that the results were reproduced consistently across multiple independent test batches.

HydroGraph Clean Power has announced that its U.S. subsidiary, HydroGraph USA Inc., has executed definitive agreements with Western International Gas & Cylinders, Inc. (“Western International”) to secure a long-term supply of acetylene gas and lease land for HydroGraph’s first large-scale U.S. graphene production facility, to be located in Bellville, Texas.

Under the Acetylene Purchase Agreement, HydroGraph USA will purchase acetylene for its Bellville, TX facility directly from Western International via pipeline for an initial ten-year term, with options for renewal. Acetylene serves as the primary feedstock for HydroGraph’s proprietary Hyperion Reactors, which convert hydrocarbon feedstocks into ultra-pure synthetic Fractal Graphene™ products through a highly efficient continuous manufacturing process Contemporaneously, the parties entered into a Ground Lease Agreement granting HydroGraph USA a long-term lease for land located at Western International’s Bellville, Texas facility. The site will host HydroGraph’s new commercial-scale graphene manufacturing facility, which will be constructed, owned, and operated by HydroGraph USA.
