Graphene is a single atomic layer of carbon atoms in a hexagonal lattice, prized for its strength, conductivity, and uses in advanced materials research.
Calculations by Xiong and Jia show a graphene-MnPS3 stack switching between altermagnetic and ferrimagnetic states across a 28 meV/f.u. sliding barrier. Under out-of-plane pressure the computed spin splitting reaches 72.2 meV and 80.2 meV in the two phases.
Reality
University of Osaka researchers drove protons to 132 MeV with a long-pulse laser and graphene targets that survived the prepulse. That shows ultrathin targets can work with long pulses, though the release reports a peak energy without the beam figures a practical accelerator needs.
Reality
Researchers report that graphene reservoirs confine sub-100-nm liquid films for cryo-EM, so ice thickness can be tuned by reservoir depth. They trace decades of trial-and-error ice preparation to thin films that drain and rupture on their own before anything freezes.
Reality
Two graphene oxide suspensions dried into opposite deposits, one a radial web and one a field of patches. Synchrotron scattering and rheology tie the difference to how tightly the nanosheets stack before the water leaves.
Reality
Researchers at four institutions report in Nature Physics that 1,550-nm circular pulses dress a graphene strip into a transient Floquet state, and a 775-nm field sets the direction of the current that flows out.
Reality
For nearly twenty years, triangular pores in hexagonal boron nitride were credited to the electron beam. A Vienna group ran the irradiation in ultra-high vacuum instead, got circles, and then dialled the triangles back in with a little oxygen.
Reality
An Amsterdam group reports it can put a tungsten disulphide monolayer exactly where it wants it, with near-unity yield. The limits worth watching are the 140 C melt step and the millimetre of usable area.
Reality
An ARC Center of Excellence team let its simulations leave the flat geometry, got rippled and sideways-shifted layers, and found X-ray scattering from real samples consistent with them. Phosphorus and nickel predictions moved with the structure.
Reality
A published test blended graphite from electronic waste with old newspaper and tap water into usable graphene. Confirming what came out of the blender still needed a university lab.
Reality
Yonsei researchers report 93.1 J/g of latent heat and 90.2 percent retention after 1,000 cycles. The paper membrane keeps 80.2 percent of that capacity; its own cycle life is not reported.
