Nature Communications, Published online: 15 April 2026; doi:10.1038/s41467-026-71800-6 The authors engineer an octahedrally rigid perovskite dielectric with a dual-cubic framework and cold-sintering-enabled microstructure, enabling stable capacitive energy storage up to 270 °C.
Nature Communications, Published online: 14 April 2026; doi:10.1038/s41467-026-71823-z Cylindrical ferroelectric/dielectric capacitors show tunable capacitance, shifting from positive to infinite or negative by varying layer thickness. Models and simulations reveal curvature boosts capacitance via stray-field energy effects.
