Domain‐Wall Circulation Gating and Pinning via Compositional Engineering of Cylindrical Nanowires

open access: yesSmall, EarlyView.
Cylindrical magnetic nanowires offer a promising platform for future three‐dimensional spintronic devices. By strategically engineering nanometer‐scale chemical modulations, a novel circulation gate is established to control domain wall propagation.

Crystallization‐Driven Helical Conjugated Polymer Nanowires for Circularly Polarized Light‐Addressable Ferroelectric Physical Unclonable Functions

open access: yesSmall, EarlyView.
Supramolecular helicity meets ferroelectricity: P3HT‐b‐PMMA helical nanowires enable handedness‐specific modulation of remanent polarization in P(VDF‐TrFE) hybrids. This platform demonstrates the first CPL‐addressable ferroelectric PUF, translating molecular chirality into secure digital authentication.

Achieving Large Uniaxial and Homogeneous Strain in Two‐Dimensional Materials

open access: yesSmall, EarlyView.
Strain is a powerful tool for tuning the electronic, magnetic, and topological properties of 2D materials ‐ particularly at high values (>3$>3$%) where many electronic and structural transitions are predicted. Our high‐yield preparation and device strain platform overcomes existing strain limitations (often <1.5$<1.5$%), enabling repeatable and ...

A Polar Topology Network Induces Elastic Stiffening in Ferroelectric Oxide Superlattices

open access: yesSmall, 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.

Spatial Statistics for Screening Molecular Structures

open access: yesSmall, EarlyView.
Deep architectures for materials discovery demand vast training data and obscure the structure‐property link. This review shows how spatial statistics offer a physically grounded alternative: voxelized fields and two‐point correlations, compressed by principal component analysis, yield convex, interpretable descriptors. Lean surrogates then reach sub‐2%
