The clock model shows the rotation alignment between the hour hand (Top hBN), minute hand (middle graphene) and second hand (Bottom hBN). The combination of top hBN, middle graphene and…
…the existence of topological electronic crystals in a unique material called twisted bilayer–trilayer graphene. This system is created by stacking ultra-thin graphene layers with a precise rotational twist, fundamentally altering…
…the University at Buffalo are developing a graphene-based composite that will hopefully serve as a rust-proofing alternative to the toxic coatings that are now being used. The researchers believe graphene’s…
…possible. “We are now looking for industry partners to help us mass-produce our graphene micro-supercapacitors,” Kaner said. Reference: “Scalable fabrication of high-power graphene micro-supercapacitors for flexible and on-chip energy storage”…
Controlling magnetic clouds in graphene. Credit: University of Manchester Scientists from the University of Manchester have shown for the first time that magnetic clouds in graphene can be controllably dissipated…
AResearchers have pioneered a novel method for engineering graphene-based supercapacitors, enabling their widespread use in renewable energy storage, portable electronics, and electric vehicles. In a newly published study, engineers from…

Artist impression of a graphene sheet. Credit: The University of Manchester By placing microscopic materials between two sheets of graphene, researchers have discovered a new technique that protects microscopic materials…
…in which bulk electrons behave like those in an insulator while surface electrons behave like those in graphene. “The swift development of graphene and topological insulators has raised questions as…
Strong, stretchable fibers made of graphene oxide can be knotted like yarn. Credit: Terrones group/Penn State By chemically exfoliating graphite into graphene flakes and mixing them into a slurry, a…
…transfer. “We thought graphene could be useful,” Preston says, “since we know it is hydrophobic by nature.” So he and his colleagues decided to test both graphene’s ability to shed…
…graphene on top of a layer of tungsten disulfide. Their results have been published on October 16, 2019, in the journal Physics Review B. Graphene, a two-dimensional version of carbon,…
…from a combination of exotic metals. They flowed atoms of each metal over the graphene-covered wafer and found the atoms formed a film on top of the graphene, in the…
…of graphene and a superconductor, which trap the graphene massless electrons between them, like a sandwich. The device is then connected to a power source. When the THz radiation hits…
Corrugations in graphene slow down the pace of traveling electrons. By pulling on the graphene sheet on two opposite sides, it is flattened and smoothed, and electron transport is improved….
Graphene light sail of 3mm in diameter with a mass of 0.25 mg ‘sets sail’ when pointed with a 1W laser. The prototype has a graphene micromembrane design that reduces…
A triangular piece of graphene is predicted to be magnetic. Credit: CIC nanoGUNE Graphene is a diamagnetic material, this is, unable of becoming magnetic. However, a triangular piece of graphene…
