Flexible ferroelectrics High-quality ferroelectric materials, which polarize in response to an electric field, are usually oxides that crack when bent. Dong et al. found that high-quality membranes of barium titanate are surprisingly flexible and super-elastic. These films accommodate large strains ...

Abstract 2D Dion−Jacobson (DJ) perovskite single crystals (PSCs) usually demonstrate better X‐ray detection performance than Ruddlesden‐Popper (RP) PSCs. However, the mechanism of the improved performance is still elusive. Here, by the aid of strong interactions between dimethylbiguanide (DGA) and P...

Abstract Dielectric capacitors are promising for high power energy storage, but their breakdown strength ( E b ) and energy density ( U e ) usually degrade rapidly at high temperatures. Adding boron nitride (BN) nanosheets can improve the E b and high‐temperature endurance but with a limited U e due...

Abstract Ferroelectric memory is one of the most attractive emerging nonvolatile memory. Conventional methods to increase storage density in ferroelectrics include reducing the storage bit size or fabricating 3D stacks. However, the former will face a physical limit finally, and the integration of s...

Neuronal activity in the medulla oblongata and neurogenic inflammation of airways were investigated in a guinea pig model induced by repeated intra-esophageal instillation of hydrochloric acid (HCl) after vagotomy. Unilateral vagotomy was performed in the vagotomy group, while a sham-operation was p...

Bragg gratings possess unique functional attributes as fundamental integrated photonic devices. A reconfigurable grating unit based on a Bragg-grating-assisted Mach–Zehnder interferometer (GAMZI) is proposed as a versatile building block for programmable photonics. By integrating identical Bragg gra...
