Large Spin‐Orbit Torque with Multi‐Directional Spin Components in Ni4W

open access: yesAdvanced Materials, EarlyView.
Ni4W is theoretically proposed and experimentally verified as a promising unconventional spin‐orbit torque (SOT) material for generating multi‐directional spins. Epitaxial Ni4W thin films with outstanding crystallinity are grown by magnetron sputtering.

Upconversion Nanoparticle‐Covalent Organic Framework Core–shell Particles as Therapeutic Microrobots Trackable With Optoacoustic Imaging

open access: yesAdvanced Materials, EarlyView.
Upconversion nanoparticle‐covalent organic framework core–shell particles provide enhanced contrast for optoacoustic imaging by leveraging the optical absorption of upconversion luminescence within the covalent organic framework matrix. Beyond their role as contrast agents, these particles enable customizable therapeutic agent loading and release, as ...

Anomalous Phonon Softening with Inherent Strain in Wrinkled Monolayer WSe2

open access: yesAdvanced Materials, EarlyView.
This study introduces the first discovery of a new local strain indicator, A2′′(Γ)$A_2^{^{\prime\prime}}( \Gamma )$ mode, for monolayer WSe2‐based excitonic applications including single photon emitter by using tip‐enhanced Raman spectroscopy. The correlative investigation with density functional perturbation theory provides the origin of the anomalous

Biomimetic Dynamics of Nanoscale Groove and Ridge Topography for Stem Cell Regulation

open access: yesAdvanced Materials, EarlyView.
Dynamic nanoscale groove‐ridge structures are engineered by flexibly conjugating RGD‐magnetic nanoparticles to nanogroove templates with variable groove widths at the molecular scale. Magnetic control enables cyclic switching between nanoscale groove and ridge states that modulates ligand accessibility of cellular integrins.

Cleanly Removable and Degradable Bio‐Based Adhesive for Flexible Displays

open access: yesAdvanced Materials, EarlyView.
Sustainable acrylic optically clear adhesives (OCAs) for foldable displays are developed by incorporating ultraviolet (UV)‐triggered debondability and lipoic acid–based degradability through visible‐light‐induced bulk polymerization. These OCAs enable residue‐free removal and degrade into small oligomers or recoverable monomers under mild conditions ...

Intrinsically‐Stretchable and Patternable Quantum Dot Color Conversion Layers for Stretchable Displays in Robotic Skin and Wearable Electronics

open access: yesAdvanced Materials, EarlyView.
Intrinsically‐stretchable, heavy‐metal‐free quantum dot color conversion layers are produced via a versatile crosslinking strategy. The color conversion layers exhibit minimal backlight leakage under mechanical strain, support high‐resolution patterning, and integrate seamlessly with micro‐light‐emitting diodes. Their incorporation in haptic‐responsive
