Nanosecond-scale simulations of the solid acids CsH2PO4 and CsHSO4 identify a “proton slingshot” mechanism for fast proton conduction. A rotating phosphate or sulfate group first carries a proton, while reorientation of the proton’s bond to oxygen extends its movement and enables longer jumps.
Researchers developed an attack that uses an AI classifier to reconstruct representative images from its private training data. In tests, the approach produced more faithful images than earlier methods while maintaining similar accuracy in identifying their target classes.
Researchers developed an iron-based cathode for protonic ceramic fuel cells that reached a peak power density of 2.2 W/cm² at 700 °C. The cell also operated stably for more than 400 hours, according to the study.
