Aerogel Fiber: A One‐Dimensional Programmable Porous Matter for Next Thermal Management Materials

Interdisciplinary Materials, EarlyView.
Aerogel fibers are redefined as one‐dimensional programmable porous matter, where thermal transport is governed by multiscale pathway engineering. By reconstructing and decoupling transport pathways from molecular to textile scales, these systems integrate insulation, radiative cooling, and adaptive thermal regulation.

Antiferroelectric Phase Transitions Under Electric Fields: A Review of Physics and Applications

Interdisciplinary Materials, EarlyView.
Field‐induced phase transitions in antiferroelectric materials, driven by electric field, temperature, or stress, enable diverse applications including energy storage, electrocaloric cooling, and negative capacitance. These transitions are regulated through compositional design, strain engineering, heterostructure, and size effect, providing a unified ...

Hierarchical Reaction‐Induced Phase Separation in Epoxy/Oligomeric Poly(phenylene ether) Blends: Multiscale Structural and Mechanical Heterogeneity

Journal of Polymer Science, EarlyView.
Hierarchical morphology does not always improve toughness. In epoxy/oPPE blends, curing creates oPPE‐rich primary domains containing nanoscale secondary heterogeneity, as revealed by microscopy, X‐ray scattering, and AFM nanomechanics. Fracture observations show that primary domain–matrix interfacial separation limits tensile ductility despite the ...

Multi‐Modal Imaging of the Loading Heterogeneity in Blended Films of Amorphous and Semi‐Crystalline Polymers During Stretching

Journal of Polymer Science, EarlyView.
Correlated and spatially resolved small and wide angle X‐ray scattering and vibrational spectroscopy have been used as contrast to image failure regions in polymer blend films. The correlated imaging approach reveals molecular detail of the mechanism of failure and molecular scale insight into an enhanced performance of polylactic acid films blended ...

Carbon dots in photocatalytic water splitting and related proton/electron‐coupled reactions: Multiscale regulation of charge dynamics and interfacial processes

Responsive Materials, EarlyView.
This review summarizes CD‐based photocatalytic water splitting as a multiscale charge‐utilization process, linking photoexcitation, charge separation, interfacial transfer, charge storage, and catalytic consumption. It highlights how CD structures and interfaces regulate charge pathways and reaction microenvironments, and how advanced characterization,

Liquid‐Processed 2D Aromatic Amorphous Carbon: Defect Engineering and Universal Transport Scaling

Small, EarlyView.
Liquid‐processed graphene oxide (GO) thin films undergo a controllable crystalline–to–amorphous transition driven by thermal quenching. By kinetically tuning oxygen‐driven defect formation during reduction, scalable 2D aromatic amorphous carbon phases are stabilized, directly linking nanoscale disorder and defect topology to electronic transport ...

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 ...

A Polar Topology Network Induces Elastic Stiffening in Ferroelectric Oxide Superlattices

Small, EarlyView.
The periodicity in BiFeO3/SrTiO3 superlattices tunes the system into a dense, elastically constrained polar texture state. This topology‐rich regime reveals a collective mechanical response in which interactions among polar topological defects restrict local deformations, producing a pronounced elastic stiffening.
