Tough and Fast Thermoresponsive Hydrogel Soft Actuators
Advanced Materials Technologies, EarlyView.This work develops tough, fast‐responding thermoresponsive double‐network hydrogels that combine excellent mechanical strength with rapid actuation. Composed of PNIPAm and ether‐based polyurethane, the hydrogels achieve ≈8 MPa compressive stress and ≈30% contractile stroke within 2 min at 50 °C, enabling temperature‐responsive fluid flow switching for ...

Advanced Optical Materials, EarlyView.Mechanisms by which excitons and charge carriers can funnel and recombine in 2D multi‐layered MAPbBr3 Ruddlesden‐Popper perovskite nanosheets are missing. This femtosecond transient absorption spectroscopy study creates a comprehensive understanding of how directed transport, exciton‐exciton annihilation, and Auger recombination occur in colloidal ...

Unidirectional Focusing of Light Using Structured Diffractive Surfaces
Advanced Optical Materials, EarlyView.This study presents a reciprocal diffractive unidirectional focusing design based on linear and isotropic layers. A set of cascaded diffractive layers is designed using deep learning to achieve efficient forward light focusing while suppressing backward propagation across various illumination angles.
