Fabrication of Chiral Liquid Crystal Pinwheel Arrays Through Capillarity‐Assisted Particle Assembly

open access: yesSmall, EarlyView.
Nucleation in chiral liquid crystals (LCs) is investigated using colloidal arrays produced by capillarity‐assisted particle assembly (CAPA) upon heating to spatially control the nucleation of the isotropic phase, enabling the fabrication of chiral pinwheel arrays.

Tunable Self‐Emulsification Via Viscoelastic Control of Marangoni‐Driven Interfacial Instabilities

open access: yesSmall Methods, EarlyView.
A striking interfacial instability–Marangoni bursting–is tamed by introducing trace polymers. Minute amounts of viscoelastic additives delay fragmentation, elongate fingers, and modulate instability wavelengths without altering droplet size. This study reveals how soft matter rheology can program self‐emulsification dynamics, offering new routes for ...

Revealing Nanoscale Solute‐Rich Clusters in Bulk Metallic Glasses by Atom Probe Tomography

open access: yesSmall Methods, EarlyView.
This study presents a new methodology that resolves a longstanding challenge in multicomponent bulk metallic glasses by revealing 3D nanoscale solute‐rich clusters via atom probe tomography. The findings further establish direct correlations between solute‐rich clustering and local hardness, offering a powerful framework for investigating structure ...

Composite Pentamode Metamaterials for Enhanced Wave Manipulation by Asymmetric Surface Structure

open access: yesSmall Structures, EarlyView.
The asymmetric pentamode surface structure can reduce the scattering from 26.3 dB to 0.96 dB and multiply the frequency range of wave manipulation. This approach results in a 95% improvement in compressive strength compared to pentamode structures with the same acoustic performance, enabling wider deepwater applications.
