Charge‐Induced Morphing Gels for Bioinspired Actuation

Advanced Functional Materials, EarlyView.
This study introduces a novel electroactive actuation mechanism that enables the gel material to generate substantial and reversible shape‐changing while preserving topological and isochoric (volumetric) equivalence. The resultant morphing behaviors can mimic the movements of muscle‐driven organelles in nature, including cilia‐like beating and ...

RoHS‐Compliant, Cu‐Zn‐In‐Se‐Based Core/Multi‐shell Quantum Dots with Efficient and Tunable Short‐Wave Infrared Emission

Advanced Functional Materials, EarlyView.
An innovative combination of size‐controlled template synthesis, partial cation exchange reactions, and dual shell passivation offers a new class of RoHS‐compliant, heavy metal‐free Cu‐Zn‐In‐Se/ZnS/Al2O3 core/shell/shell quantum dots (QDs), exhibiting long‐range tunability, highly efficient SWIR emission with remarkably narrow photoluminescence ...

Microsphere Autolithography—A Scalable Approach for Arbitrary Patterning of Dielectric Spheres

Advanced Functional Materials, EarlyView.
MicroSphere Autolithography (µSAL) enables scalable fabrication of patchy particles with customizable surface motifs. Focusing light through dielectric microspheres creates well defined, tunable patches via a conformal poly(dopamine) photoresist. Nearly arbitrary surface patterns can be achieved, with the resolution set by the index contrast between ...
