Development of Heat Engines Powered by Twisted and Coiled Polymer Fiber Actuators

Advanced Materials Technologies, EarlyView.
Continuously rotating engines driven by thermally responsive actuating materials can turn waste heat into useful energy. For the first time heat engines operated by twisted and coiled polymer fiber actuators are demonstrated with engine design guided by two simple analytical models.

Responsive Visible‐Wavelength Metasurfaces from Porous Silicon Based on Fano Guided‐Mode Resonance

Advanced Optical Materials, EarlyView.
The article introduces mesoporous silicon metasurfaces (pSi‐MS) supporting Fano guided‐mode resonances in the visible regime. By combining top‐down lithographic patterning of 2D gratings with bottom‐up electrochemical porosification, the approach realizes a new class of responsive metasurfaces, enabling highly sensitive and portable platforms for small

Improved Disorder Resilience in Small‐Footprint Photonic Cavities with Periodicity Breaking

Advanced Optical Materials, EarlyView.
Compact photonic crystal cavities with engineered aperiodicity are demonstrated to sustain high quality factormodes and enhanced reproducibility within a minimal footprint. Combining numerical optimization and near‐field measurements, the study reveals how controlled periodicity breaking improves disorder resilience, offering a robust and scalable ...

Mitigating Singlet Exciton Back‐Transfer using 2D Spacer Layers for Perovskite‐Sensitised Upconversion

Advanced Optical Materials, EarlyView.
The efficiency of bulk perovskite‐sensitised upconversion is hindered by parasitic singlet back‐transfer. A 2D perovskite spacer layer is introduced to weaken this loss pathway by increasing the separation between the sensitiser and the emitter. The spacer layer enhances the upconversion efficiency at lower excitation powers and improves the stability ...

Vat Photopolymerized HEMA/HEA Hydrogels for Solvent‐Responsive Transparency and Optical Encryption

Advanced Optical Materials, EarlyView.
Vat‐photopolymerized HEMA/HEA hydrogels exhibit reversible transparency‐opacity switching via hydration‐induced microphase separation and solvent exchange. The printed materials enable hydration sensing, optical encryption, and information storage, while maintaining high ductility and reversible rheology.
