Polarizing ultrathin ferroelectric BaTiO3 films through interfacial layer polarization

An important requirement for the integration of ferroelectric thin films into devices is deterministic control of the polarization state in films of only a few unit cells in thickness. Here, we utilize the charged atomic planes of (001)-oriented SmNiO$_3$ (SNO) buffer layers as a polarizing template to stabilize the polarization in ferroelectric BaTiO ...

Decoupling Li+ Transport in Self‐Healing Polymer Dual‐Salt Electrolytes for Room Temperature Lithium Metal Batteries

Advanced Functional Materials, EarlyView.
A self‐healable polymer matrix, crosslinked via dynamic imine bonds, is synergistically coupled with a LiPF6–LiDFOB dual‐salt system to decouple Li+ from the polymer matrix, enabling fast Li+ transport. This strategy offers an effective pathway toward high‐performance, next‐generation gel‐polymer‐based Li‐metal batteries.

Ga–O–Pt Electronic Bridges Bypass Single‐Site Constraints for pH‐Universal Hydrogen Evolution

Advanced Functional Materials, EarlyView.
Well‐defined oxygen‐bridged Ga–O–Pt catalysts are constructed for pH‐universal hydrogen evolution, highlighting the relationship between oxygen‐bridged electronic coupling, rapid surface hydrogen redistribution, and superior catalytic performance. ABSTRACT Single‐site descriptors often fail to capture hydrogen evolution on heterometallic interfaces ...

Lone‐Pair‐Induced Lattice Distortion in Lead‐Free Hybrid Perovskites for High‐Performance Nanogenerators

Advanced Functional Materials, EarlyView.
A lead‐free tin‐based hybrid perovskite is designed in which stereochemically active lone‐pair electrons on tin distort the crystal lattice and break its symmetry. Blended into a flexible polymer, the material converts pressure into electricity at milliwatt‐scale power density and continues working far below freezing, powering a commercial wristwatch ...

Defect‐Mediated Inelastic Light Scattering by Infrared Phonons in Hexagonal Boron Nitride

Advanced Functional Materials, EarlyView.
Optically active defects in hexagonal boron nitride enable inelastic stimulated light scattering mediated by infrared‐active phonons, relaxing conventional Raman selection rules. Defect engineering enhances the Stokes‐conversion process and activates both TO‐ and LO‐phonon scattering channels.

Magneto‐Ionic Devices With Polymer‐Based Electrolytes

Advanced Functional Materials, EarlyView.
Polymer electrolytes are introduced for magneto‐ionic devices based on hydroxide and hydrogen ions. The magneto‐ionic effect results in a pronounced voltage‐controlled variation of coercivity in both devices. The switching speed is in the range of 100 ms.
