Aqueous Vanadium Anode Reported to Convert Reversibly Between V2O3 and Na3VO4: 700 mAh/g on an Active-Material Basis, With a Projected (Not Measured) 110 Wh/kg Whole Battery
Analysis based on information available as of 2026-10-23. 30-second summary What: A Nature Materials paper, “Switching from insertion to conversion for multielectron aqueous vanadium batteries” (26 authors, first author Hongrun Jin; online 2026-07-07; DOI 10.1038/s41563-026-02666-8), reports that OH–-mediated activation cleaves V-O bonds and moves a vanadium anode from one-electron insertion to a four-electron conversion between…

Layer Number Sets the Chern Number in Twisted Rhombohedral Graphene: An Abstract-Level Reading of a Single-Device-Scale Transport Experiment
Analysis based on information available as of August 17, 2026. 30-second summary What: A Nature Materials paper (online August 14, 2026) reports electrical-transport experiments on twisted monolayer-multilayer rhombohedral graphene (1+N). In devices with N = 3, 4 and 5 layers, the authors report quantum anomalous Hall (QAH) states with Chern number C = N. They…

Spectroscopy of Capped Bilayer Nickelate Films Associates Interlayer Orbital Hybridization With Superconductivity: A Mechanism Interpretation, Not a Device and Not a Proof of Cause
Analysis based on information available as of 2026-10-19. 30-second summary What: A collaboration with authors at Zhejiang University, Peking University and Nanjing University used a protective capping layer to stabilize superconducting bilayer Ruddlesden-Popper nickelate thin films, (La,Pr)3Ni2O7, and measured them directly with X-ray absorption (XAS) and resonant inelastic X-ray scattering (RIXS). The published Nature Materials…
