Controllable Topological Domain Arrays in Periodically Wrinkle‐Patterned Pb(Zr0.2,Ti0.8)O3 Thin Films

Information &Functional Materials, EarlyView.
We demonstrate reversible mechanical and electrical control of ordered center‐type topological domains in wrinkled PZT films, with high‐conductivity channels at domain cores, enabling multifield manipulation for future topological devices. ABSTRACT Ferroelectric topological domain textures hold promise as key building blocks for next‐generation ...

Local‐distortion regulation of small‐polaron transport: A design degree of freedom for thermoelectric oxides

InfoMat, EarlyView.
The thermoelectric performance of oxides is closely linked to how small polarons move through a locally distorted crystal lattice. Here, we compare Ce‐ and La‐doped CaMnO3 with comparable carrier concentrations but distinctly different local distortion backgrounds, showing that stronger distortion more strongly traps small polarons and delays their ...

Topological Structuring of Adhesive Layers to Enhance Resistance against Interfacial Fracture

Small, EarlyView.
A hybrid bonding method that combines chemical affinity with mechanical interlocking is demonstrated. This approach uses a solution‐based technique to create a porous layer that strongly adheres to one substrate and templates a robust mechanical interlock with the other adherend. By tuning the pore geometry, crack propagation is effectively suppressed,

Interferometric Vector Piezoresponse Force Microscopy for Simultaneous Ferroelectric Domain and Crystallographic Orientation Mapping in Uniaxial Ferroelectric Polycrystals

Small, EarlyView.
Interferometric vector piezoresponse force microscopy is used to reconstruct crystallographic grain orientations in polycrystalline ferroelectrics directly from local electromechanical response. The approach reveals grain orientation, polarization direction, and domain structure simultaneously, establishing a pathway toward EBSD‐like orientation ...

Precise Nanoscale Mapping of Electric Fields Across Random Grain Boundaries in Polycrystalline Oxides Using Precession‐Assisted 4D‐STEM

Small, EarlyView.
Correlative singular value decomposition 4D‐STEM analysis of the potential, electric field, and charge density distributions with crystal orientation, strain across grain boundaries in polycrystalline materials. ABSTRACT Space charge layers (SCLs) at grain boundaries play a crucial role in modulating electric fields and thereby influence functional ...

A Comprehensive Multimodal Study of La0.45Sr0.45TiO3 Structure as Matrix for the Exsolution Process: From the Average to the Local Scale

Small, EarlyView.
We present a multimodal, multiscale study of La0.45Sr0.45TiO3 combining experimental and computational approaches to probe its local structure. The results reveal A‐site ordering along [001] and loss of centrosymmetry driven by electrostatic effects.

Engineering Janus Nanofiber Interfaces for Simultaneous Triboelectric Enhancement and Wearable Comfort

Small Methods, EarlyView.
A moisture‐wicking Janus bilayer triboelectric nanogenerator (MW‐JBT) that integrates directional moisture transport with dielectric‐engineered electrospun nanofibers was developed. When incorporated into a plantar sensing system and combined with a deep learning algorithm, the MW‐JBT achieved a fall‐detection accuracy of 88.5%. This study demonstrates
