Inspired by octopuses, actuating legs based on soft materials are fabricated with programmed chiroptical properties and mechanical behaviors to achieve dynamic color modulation and reversible shape morphing, and these legs are developed into a modular OCTOID system.

Photo‐Reconfigurable Supercoupling Induced Transparency in On‐Chip Topological Edge State Cavities
A novel supercoupling induced transparency (SIT) is demonstrated in a valley‐Hall photonic crystal. The valley vortices enable the supercoupling between a leaky and a guided topological edge state cavity even across a distance of 4.3 wavelengths, inducing a transparency window with negligible reflection.

This Review proposes an interface‐centric framework for large‐area 2D materials integration, linking wafer‐scale single‐crystal epitaxy, clean transfer and deterministic stacking, and interface‐dominated structure–property–device correlations. We summarize how interfacial symmetry and energetics govern nucleation/coalescence and adhesion‐controlled ...

Triple‐Cation Engineering for Efficient and Stable Sky‐Blue Quasi‐2D Perovskite LEDs
Doping of the quasi‐2D film improves stability and enables higher photoluminescence quantum yield. Quasi‐2D metal‐halide perovskite LEDs (PeLEDs) are promising for displays but remain limited by trap‐mediated loss and short lifetimes, especially in the blue. Here, we report a triple‐cation A‐site doping strategy by co‐incorporating Rb+ and guanidinium (

Atomistic Understanding of 2D Monatomic Phase‐Change Material for Non‐Volatile Optical Applications
Antimony is a promising monatomic phase‐change material. Scaling down the film thickness is necessary to prolong the amorphous‐state lifetime, but it alters the optical properties. The combined computational and experimental study shows that, as thickness decreases, the extinction coefficient and optical contrast are reduced in the near‐infrared ...

Photothermal Transport for Guiding Nanoparticles Through the Vitreous Humor
Nanosecond laser irradiation of the clinically approved dye indocyanine green (ICG) enables light‐guided nanoparticle transport within the vitreous humor. The combined use of ICG and pulsed laser illumination induces localized convection and thermophoresis, directing particles toward illuminated regions.

High temperature, experimental thermal memory based on optical resonances in photonic crystal slabs
We present an experimental thermal memory with direct optical control and readout. Information is stored in the internal temperature of the device, while laser illumination is used to read, write, and erase stored bits.

Few‐layer La2CoO4 nanosheets are produced via phonon‐resonance‐assisted cleavage of the rock‐salt layers in the Ruddlesden‐Popper structure under the 20 kHz resonance condition, enabling controlled exfoliation into ultrathin sheets. The nanosheets show improved gas‐sensing capability, delivering an 86.67% response to 1 ppm NO2 at room temperature ...

The BA2MA3Pb4I13, where (BA is butylammonium, MA is methylammonium) quasi‐2D halide perovskites are identified as a promising material with a suitable bandgap of 1.9 eV for indoor light harvesting. A combination of lower thickness of 260 nm, better phase purity and greater (202) crystal orientation obtained from preheating, yielded a champion power ...
