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,

Engineering Cobalt‐Based Thin Films for Fischer–Tropsch Synthesis

Small, EarlyView.
Cobalt thin films with tailored crystalline phases and oxidation states serve as well‐defined model Fischer–Tropsch catalysts. In situ synchrotron GIXRD reveals distinct reduction behaviour and phase evolution, while catalytic testing demonstrates phase‐dependent hydrocarbon selectivity and improved structural stability. These model thin‐film catalysts

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 ...

Thermal Instability Pathways of Aluminum‐Based Nanocomposites: The Role of Alloying‐Element‐Driven Precipitation and Amorphous Interlayers

Small, EarlyView.
Thermal instability mechanisms governing novel Al‐based PVD/ALD nanocomposites are uncovered through synchrotron XRD, STEM, APT, and micromechanical testing. Temperature‐dependent crystallite evolution reveals a defined stability window before degradation dominates, offering new insight into the design of thermally robust, functional Al‐based ...

Engineering Flexible Nanofibrous Hydroxyapatite Scaffolds With Tunable Degradation and Mechanical Properties for Bone Regeneration

Small, EarlyView.
Conventional hydroxyapatite ceramics are brittle and poorly resorbable, limiting their use in bone repair. To overcome these limitations, flexible scaffolds are fabricated using ceramic nanofibers as structural building blocks. Adjusting nanofiber characteristics allows modulating the mechanical properties and degradation, providing a versatile ...

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
