Advanced Science, Volume 13, Issue 13, 3 March 2026.The electric‐field‐driven antiferroelectric‐to‐ferroelectric phase transition in epitaxial PbZrO3 films is directly visualized by in situ aberration‐corrected scanning transmission electron microscopy. A sequential transition pathway involving an orthorhombic ferrielectric phase and a monoclinic ferroelectric phase, ultimately stabilizing into a ...

Electric Field‐Induced Phase Transition Behaviour in Sodium Bismuth Titanate‐Based Ceramics
Advanced Energy and Sustainability Research, Volume 7, Issue 3, March 2026.This review establishes a framework correlating NBT‐based ceramic performance with geometric descriptors: tolerance factors and octahedral tilt strength. It rationalises transitions between ergodic and non‐ergodic relaxor states across major solid solutions.

Control of Covalent Bond Enables Efficient Magnetic Cooling
Advanced Materials, Volume 38, Issue 7, 2 February 2026.Giant and reversible magnetocaloric effect (MCE) is achieved by tuning covalency through sub‐unit‐cell chemical engineering, establishing a novel design principle for effective hysteresis control in magnetocaloric materials. Abstract Magnetic cooling, harnessing the temperature change in matter when exposed to a magnetic field, presents an energy ...
