Localized Ion Irradiation Enables Topography‐Free High‐Tc Superconducting Metamaterials

Advanced Optical Materials, EarlyView.
A topography‐free oxygen ion‐irradiation strategy is demonstrated for patterning superconducting YBCO terahertz metamaterials without physical material removal. The approach preserves film integrity while enabling large spectral tunability, ultrafast optical modulation, and dual‐band resonance control, providing a scalable platform for low‐loss ...

Halide Defect Passivation in CsPbBr3 Nanocrystals Mediated by the Friedel–Crafts Reaction: Enhanced PLQY and Structural Stability Without Bandgap Modulation

Advanced Optical Materials, EarlyView.
Post‐treatment of CsPbBr3 nanocrystals with an AlBr3/CH2Br2 solution does not induce Al3+ substitution at Pb2+ sites. Instead, a Friedel–Crafts reaction generates Br− ions that passivate halide defects, markedly increasing PLQY and improving structural stability without bandgap modulation.

Electrically Reconfigurable Optical Initialization of Spin Valley Polarization in Monolayer WS2 Enabled by Switchable Dual‐Mode Liquid Crystal Lasers

Advanced Optical Materials, EarlyView.
This work presents an electrically controllable approach to spin–valley polarization in monolayer WS2 by integrating it with a dual‐mode liquid crystal laser. Applying an external field triggers phase transitions that switch the laser emission between helicity‐defined band‐edge lasing and unpolarized random lasing.

Molecular Appendix Adjusted Architectural Propagations of Red‐Light Controlled Macroscopic Photoactuating Performances

Advanced Robotics Research, EarlyView.
Amphiphilic chloroazobenzenes, bearing different amino acids as end groups alanine, phenylalanine, and valine, exhibit excellent photoisomerizations. Varying structures of three amino acid groups participate in supramolecular formations and therefore photoinduced morphological transformations via adjusting intermolecular interactions. These interaction

A Superlubricated Magnetically Steerable Microcatheter with Integrated Optical and Fluidic Channels

Advanced Robotics Research, EarlyView.
A magnetically steerable microcatheter with integrated optical and fluidic channels is developed for multifunctional navigation in tortuous anatomical environments. A surface‐grafted hydrogel coating enables low‐friction actuation. The device demonstrates stable light and fluid delivery during magnetic manipulation, offering a compact platform for ...
