Graphene-Info: the graphene experts

Graphene Manufacturing Group (GMG) has announced that it has secured a 20-year US patent and received approval in China for its graphene-based engine oil additive, G LUBRICANT, marking a further step in the company’s efforts to establish international intellectual property protection for the product.

The company said the latest developments build on a previously accepted patent covering the European region, with applications in several other countries still under review.

Researchers from Brown University, Harvard University and National Institute for Materials Science (Tsukuba) have reported new insights into how superconductivity, electronic nematicity and strange metallicity are connected in 'magic-angle' twisted trilayer graphene, using angle-resolved transport measurements to track how these phases evolve.

Superconductivity - where electrical resistance drops to zero - is often linked to a breaking of rotational symmetry in the electronic system, known as nematicity. At the same time, many materials already show directional differences in electrical transport (anisotropy) before becoming superconducting. This has made it difficult to determine whether the symmetry breaking in the superconducting state is intrinsic, or simply inherited from the normal metallic phase. To address this, the researchers developed a method that measures electrical resistance as a function of direction. Instead of probing transport along a single axis, they continuously rotated the direction of current flow and mapped how resistance changes with angle. This allowed them to directly compare the angular behavior of three closely related states: the normal metallic phase, the superconducting phase, and the so-called strange metal phase, which exhibits unconventional temperature-dependent resistance.

Researchers at India's Cochin University of Science and Technology have developed a bifunctional polyaniline/reduced graphene oxide (PRGO) interlayer integrated into a lithium-sulfur (Li-S) battery separator, demonstrating a practical route to mitigating polysulfide shuttling while improving electrochemical performance.

Li-S systems offer a theoretical specific capacity of 1675 mAh g⁻¹ and energy density approaching 2600 Wh kg⁻¹, but their commercialization has been hindered by sulfur’s extremely low conductivity (~5×10⁻³⁰ S cm⁻¹) and the dissolution and migration of lithium polysulfides (LiPSs). These soluble intermediates form during discharge - initially at 2.1–2.4V (long-chain polysulfides, ~25% of capacity, 418 mAh g⁻¹) and then at 1.6–2.1V (short-chain species, ~75%, 1257 mAh g⁻¹) - and readily diffuse toward the lithium anode, causing active material loss and rapid capacity fading.

Black Swan Graphene has announced that it has completed the acquisition of Falpaco Rubber and Plastic Inc. ("Falpaco"), a Québec-based manufacturer specializing in the custom molding of plastic and rubber components, for total consideration of CA$12.7 million (around US$9.2 million).

The Acquisition represents a key step in Black Swan's strategy to accelerate the commercialization of graphene products by vertically integrating downstream manufacturing capabilities and moving closer to end customers. By combining Black Swan's proprietary graphene materials and formulation expertise with Falpaco's injection molding know-how, customer relationships, and industrial scale, the Company believes it is uniquely positioned to shorten development cycles and transition more rapidly from product validation to commercial adoption.

Graphene Manufacturing Group (GMG) has provided a progress update on its Graphene Aluminium-Ion Battery technology (“G+A CELLS”) being developed by GMG and the University of Queensland (“UQ”) under a Joint Development Agreement with Rio Tinto, one of the world’s largest metals and mining groups, and with the support of the Battery Innovation Center of Indiana (“BIC”) in the United States of America.

Increase in Energy Density for G+A CELLS since December ’25 Update

The GMG G+A CELLS have reportedly demonstrated superior performance characteristics when compared to a representative market leading ultra-fast charging batteries, the Lithium Titanate Oxide (“LTO”) batteries, which can be sold at a premium price of up to US$1200/kWh.

Researchers at the Max Planck Institute for Polymer Research, University of Cambridge, Institute for Basic Science (IBS), Korea University and Durham University have uncovered how graphene can appear “wetting transparent” at large scales while still reshaping water structure at the nanoscale.

Graphene on a substrate and in contact with water underpins technologies from desalination and energy storage to sensing, electrocatalysis, and neuromorphic devices, yet its wettability has remained controversial. Suspended graphene on water is intrinsically hydrophobic, but when graphene is supported on oxides or ionic crystals, macroscopic contact‑angle measurements show that the apparent wettability is largely dictated by the underlying substrate - an effect known as wetting transparency. The new work asks the question: do substrate electric fields simply pass through graphene, or does graphene’s pronounced polarizability first reshape those fields and thereby mediate how water is organized at the interface?

HydroGraph Clean Power has announced the opening of its new Austin headquarters, having received its certificate of occupancy in March 2026. The new facility centralizes key executive and operating functions, as well as expands the Company’s research and production capabilities in support of continued growth activities.

“We are excited to officially open our new U.S. headquarters, a key milestone underpinning a substantial increase in our research, development and manufacturing capabilities,” said Kjirstin Breure, President and Chief Executive Officer of HydroGraph. “In addition to centralizing key administrative functions into Texas, our new office will facilitate a notable expansion of our R&D capabilities, the operation of two active Hyperion Reactors on site, and serve as the control hub for our planned large-scale production facility that is anticipated to support up to 350 tons per year of capacity.”
