Thermoresponsive Self‐Healing Carbon Nanotube‐Reinforced Dual‐Network Hydrogels for Wearable Sensors and Information Concealment

Advanced Materials Technologies, EarlyView.
A CNT‐reinforced dual‐network hydrogel combines ionic liquid‐mediated thermoresponsiveness, dynamic covalent crosslinking, and conductive nanostructures within a single adaptive material. The hydrogel exhibits ultrafast gelation, autonomous self‐healing, >1000% stretchability, reversible optical switching, and stable electromechanical sensing, enabling

Coherent Absorption Reveals Colors Hidden in a Grey Fabry–Pérot Cavity

Advanced Optical Materials, EarlyView.
A dielectric thin film shows colors depending on its thickness; this effect can be used to encode information normally accessible through single‐beam spectroscopy. We developed a method to conceal this kind of information, based on coating the dielectric with a matched conductor, that suppresses the color‐bearing thin‐film resonances.

Basis‐Independent Geometric Phase Modulation in Circularly Birefringent Plasmonic Structures

Advanced Optical Materials, EarlyView.
Here we introduce a plasmonic metasurface composed of spatially rotated chiral spiral unit cells designed to produce space‐variant circular retardance. This generates a geometric phase ramp equivalent to a blazed grating, leading to polarization dependent diffraction orders in momentum space.

Harnessing Ultrafast Optical Pulses for 3D Microfabrication by Selective Tweezing and Immobilization of Colloidal Particles in an Integrated System

Advanced Photonics Research, Volume 6, Issue 5, May 2025.
Microfabrication using nano‐ to micron‐sized blocks has transformative potential for next‐gen electronics, optoelectronics, and materials. Traditional methods are limited by scalability and precision. STIC, a single‐laser system for precise colloid manipulation and immobilization using femtosecond lasers, is introduced that enables efficient 3D ...
