Graphene-Info: the graphene experts

GIT Coatings has introduced XGIT‑VORTEX™, a new graphene-based propeller coating system for marine applications. 

XGIT‑VORTEX is built on GIT’s Amphiphilic Graphene Nanonetwork (AGN) technology and is configured as a dedicated three-layer propeller system. The foul-release topcoat is designed to deter fouling attachment and keep propellers cleaner over time, while a reinforced mid‑coat acts as the structural layer to absorb cavitation stress and help reduce coating damage at blade edges and tips. Together with a low-friction surface, the system aims to maintain long-term propeller smoothness throughout the drydock cycle.

Premier Graphene has announced that its Mexican affiliate, HGI Industrial Technologies S.A.P.I., has secured two new contracts to supply the Mexican military. The agreements cover the provision of military tactical belts and nylon-cotton ripstop fabric, both considered mission-critical materials within active defense supply programs. HGI and Premier have already initiated coordination with suppliers, manufacturers, and logistics partners to support timely execution of the contracts.

The company indicated that these awards reflect growing institutional confidence in HGI’s capabilities, following prior defense-related supply engagements. The contracts are expected to contribute to recurring revenue streams and demonstrate the company’s ability to operate across multiple supply categories within the defense sector.

Researchers at the University of Washington, University of British Columbia, Florida State University and National Institute for Materials Science in Tsikuba have reported superconductivity in rhombohedral multilayer graphene, revealing a rich set of superconducting and topological phases arising from its unusual surface-focused electronic structure.

In rhombohedral (chiral-stacked) graphene, low-energy electrons are not spread throughout the material but instead concentrate almost entirely on the top and bottom layers, with very little charge in the interior. As more graphene layers are added, the density of available electronic states near charge neutrality increases, making the system more prone to interaction-driven phases such as superconductivity.

Sparc Technologies has announced that Petro Vietnam Paint will incorporate its ecosparc graphene additive into the company’s PERAPHENE range of steel protective coatings, targeting use in highly corrosive environments.

Petro Vietnam Paint’s decision follows both in‑house testing and third‑party validation, which reportedly showed improved anti‑corrosion performance compared to other graphene materials currently evaluated. The ecosparc‑enhanced PERAPHENE products are expected to become commercially available later this year for applications in marine, offshore, industrial and infrastructure markets.

Researchers from the Max Planck Institute, National Center for Nanoscience and Technology in Beijing, University of Warsaw, TUD Dresden University of Technology, University of Münster, Sichuan University, Friedrich-Alexander-Universität Erlangen-Nürnberg, Empa and Chinese Academy of Science have developed a cyclophane-based molecular shielding strategy that enables the isolation of individual graphene nanoribbons (GNRs) while simultaneously tuning their optoelectronic properties.

Graphene nanoribbons' practical use has long been limited by strong π–π stacking interactions that drive aggregation into bundles, masking intrinsic properties and preventing reliable integration into single-ribbon devices. To address this, the team designed cyclophane-type bridges that sterically shield the GNR backbone while introducing controlled internal strain. Three cyclophane-shielded GNRs (CsGNRs), labeled 1a–c, were synthesized with different tether lengths (benzene–C20–benzene for 1a, C20 for 1b, and C14 for 1c). These structures were derived from ethynyl-substituted cyclopentadienone-based cyclophane monomers, alongside model nanographenes (2a–c) based on a hexa-peri-hexabenzocoronene core.

Solidion Technology, an advanced battery technology solutions provider, has announced that it has entered into a securities purchase agreement with a new institutional investor for the purchase and sale of 2,333,000 shares of common stock (or common stock equivalents) in a private placement priced above market under Nasdaq rules. The offering is expected to result in gross proceeds of $35 million, before deducting offering expenses. 

The Company intends to use the net proceeds from the offering to support the commercialization of its patented Extreme-Climate Battery technology, fulfill customer demand, expand inventory, advance the building and testing of prototypes, and for working capital and general corporate purposes.

Vorbeck Materials has secured a $6.6 million contract from the U.S. Defense Logistics Agency (DLA) to support the development and deployment of its PFAS-free, graphene-enabled firefighting foam technology. The agreement is expected to strengthen the company’s operations in North Dakota while advancing environmentally safer alternatives to conventional firefighting agents that contain harmful “forever chemicals.”

Vorbeck’s solution includes a flame-retardant formulation that can be mixed with seawater, offering significant advantages for naval applications such as shipboard fire suppression. The technology is also suited for extreme cold environments, where saltwater’s lower freezing point enhances operational reliability.
