Graphene-Info: the graphene experts

Researchers at The University of Manchester, working with the UK’s National Physical Laboratory (NPL) and 15 international partners, have developed a new protocol, using transmission electron microscopy (TEM), which is meant to underpin a new ISO technical specification for graphene.

The results of the large interlaboratory selected area electron diffraction (SAED) comparison study, where the collaborating laboratories measured and analyzed nominally identical samples of chemical vapor deposited (CVD) graphene, were recently presented. Large variations were observed in the measured ratios of diffraction spot intensities, with the largest variance associated with poor quality SAED data resulting from poor specimen handling and storage. To inform the reliable determination of monolayer thickness from SAED patterns, the team provided a description of best practice for specimen handling, TEM operation, data collection and analysis. The results of this work have been directly incorporated into ISO/TS 21356-2 for the characterization of graphene sheets. 

Researchers from the University of Barcelona, Jaume I University, Slovak University of Technology and University of Valencia have realized graphene-enhanced hybrid photodetectors by integrating inkjet-printed mixed-phase CsPbBr₃/Cs₄PbBr₆ perovskite films directly onto graphene platforms. In this architecture, a high-mobility 2D graphene channel is intimately coupled to a photoconductive perovskite layer, enabling highly efficient photogating and broadband charge transport across the device.

The graphene channel serves as an ultrafast, low-noise pathway for photoinduced carriers, translating small changes in perovskite charge density into large modulations of graphene conductance. This strong photogating effect, together with the mixed-phase “raisin bread” perovskite morphology that confines and stores carriers, yields very high photoconductive gain. Furthermore, the use of chemical-vapor-deposition graphene and maskless inkjet printing allows direct perovskite deposition onto graphene without lithography on top of the 2D layer, preserving graphene quality and supporting integration on large-area and potentially flexible substrates.

Researchers from China's Northeastern University, Shenyang Jusheng New Material Technology, Key Laboratory of Medical Image Computing, Shenyang Aerospace University and Australia's University of New South Wales have developed a polyurea-based nanocomposite spray sensing coating reinforced with covalently functionalized graphene nanoplatelets, offering a scalable solution for structural health monitoring in demanding environments.

Preparation and Main Properties of Graphene NanoPlatelet-functionalized Polyurea Coatings.

Structural health monitoring (SHM) in harsh and complex conditions remains challenging, as conventional sensors often lack conformability, mechanical durability, and long-term stability. In their recent study, the team outlines a new approach - a spray-applied polyurea nanocomposite sensing coating that integrates functionalized graphene nanoplatelets to combine robust mechanical performance with reliable, real-time damage and strain monitoring for infrastructure and automotive structures.

At CES 2026, Japanese startup 3DC showcased a new 3D graphene nanomaterial designed to improve fast-charging and high-power battery performance. The material, called Graphene MesoSponge (GMS), uses a porous, nanoscale structure that allows electrons to move more freely inside battery electrodes. Unlike flat graphene sheets, GMS forms a connected internal network, which 3DC says reduces resistance and improves charging efficiency.

Founded in 2022, 3DC is commercializing research that began nearly a decade earlier at Tohoku University. The company is backed by Open Innovation funding from Hyundai and is currently operating at pilot scale while working with global battery manufacturers.

Directa Plus recently updated that it expected to report modest revenue growth and a significantly improved earnings performance for the year ended 31 December, supported by cost controls, operational efficiencies and progress across its graphene and environmental remediation businesses.

The Company expected 2025 revenue of €7 million, up from €6.66 million the prior year, with its adjusted EBITDA loss broadly in line with market expectations at around €2.5 million, compared with €3.64 million in 2024. It said the improvement reflected what it described as disciplined cost management and operational efficiencies delivered during a transitional year.

Researchers from Israel's Weizmann Institute of Science and Japan's National Institute for Materials Science have reported an Aharonov–Bohm interferometer in bilayer graphene, using it to reveal non-Abelian anyons whose collective quantum state can remember the history of their exchanges - a crucial resource for topological quantum computing.

In this work, ultraclean bilayer graphene is tuned into an even‑denominator fractional quantum Hall state, where strongly interacting electrons in a two‑dimensional carbon lattice fractionalize into anyons with unusual charge and statistics. The device geometry forces an anyonic excitation to travel along a loop around an island containing other anyons and magnetic flux, so that Aharonov–Bohm interference in the encircling wave function shows up directly as oscillations between high and low electrical resistance.
