When Cellulose Moves: Smart Sensors and Actuators

open access: yesAdvanced Materials Technologies, EarlyView.
This review highlights cellulose‐derived soft actuators alongside with cellulose‐based sensors. Emphasis is placed on their integration into multifunctional devices that couple sensing and actuation to mimic natural motion and adaptability. We also discuss the challenges of achieving robust, reversible, and multi‐stimuli‐responsive motion, and outline ...

High‐Transmission Mid‐Infrared Bandpass Filters using Hybrid Metal‐Dielectric Metasurfaces for CO2 Sensing

open access: yesAdvanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This article presents a hybrid metal‐dielectric metasurface in transmission mode for mid‐infrared (MIR) spectroscopy. Composed of germanium on aluminium cylinders atop a calcium fluoride substrate, the metasurface achieves 80% transmission efficiency at λ = 2.6 µm with a narrow full‐width‐half‐maximum of 0.4 µm.

Influence of Outcoupling Layers on Top‐Emitting Perovskite Light‐Emitting Diodes

open access: yesAdvanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
Top‐emitting perovskite LEDs offer benefits over typical bottom‐emitting architectures, toward lasing, improved thermal management, and on‐chip fabrication compatibility. Outcoupling layers offer a strategy uniquely applicable to top‐emitting LEDs to optimize EQE by improving optical outcoupling.
