Programming Structural Symmetry and Emission in Low‐Dimensional Hybrid Perovskites via Time and Temperature

Advanced Science, EarlyView.
We demonstrate programmable structural symmetry and emission in benzylammonium‐based low‐dimensional hybrid perovskites. Continuous shaking transforms orthorhombic platelets into a lower‐symmetry monoclinic phase with broadband emission, whereas thermal activation drives the reverse pathways toward a higher‐symmetry configuration resembling the ...

Wake‐Up and Fatigue under Electrical Cycling in HfO2‐Based Ferroelectrics: Mechanisms and Strategies toward Reliable Devices

Advanced Science, EarlyView.
HfO2‐based ferroelectrics exhibit wake‐up and fatigue behaviors during electrical cycling, significantly affecting device endurance and reliability. These phenomena are governed by defect dynamics, including oxygen vacancy redistribution and charge trapping.

Revealing the Giant Electromechanical Effects in Yttria‐Stabilized Zirconia Single Crystal

Advanced Science, EarlyView.
Giant electromechanical responses are uncovered in yttria‐stabilized zirconia single crystal (SC‐YSZ), exhibiting pronounced orientation dependence. The giant electrostriction and piezoelectricity are directly correlated with the long‐range transport kinetics of oxygen vacancies.

Long Noncoding RNA PCALRx Interacts with Pyruvate Carboxylase to Drive Multi‐Organ Developmental Toxicity in Zebrafish Embryos Exposed to Amoxicillin

Advanced Science, EarlyView.
Embryonic amoxicillin exposure disrupts multi‐organ development in zebrafish larvae through a lncRNA–metabolic enzyme regulatory axis. PCALRx associates with pyruvate carboxylase, promotes PC protein ubiquitination, and impairs mitochondrial energy metabolism, while vitamin B1 partially restores PC‐centered metabolic function and developmental outcomes.

High‐Entropy Engineering and External Magnetic Field Modulation Synergistically Enhance the H2S Sensing Performance of Rare‐Earth Perovskite Ferrites

Advanced Science, EarlyView.
A novel high‐entropy perovskite oxide, (Gd0.2Tb0.2Dy0.2Ho0.2Er0.2)FeO3, was successfully synthesized for advanced hydrogen sulfide gas detection. By synergistically coupling high‐entropy‐induced local lattice distortion with weak magnetic field modulation, the tailored material generates abundant active sites. This innovative dual strategy dramatically
