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.

Advances in Safe, Flexible, and Stretchable Batteries for Wearable Applications

Advanced Materials Technologies, EarlyView.
Unlike previous reviews centered on component‐based deformability, this work highlights safety‐driven design strategies for flexible and stretchable batteries. By integrating material‐level engineering, geometry‐controlled structures, biocompatibility, and self‐protection mechanisms, it establishes a unified framework that connects mechanical ...

Zone‐Sectored Organic Crystals with Spatially Resolved Exciton Dynamics

Advanced Optical Materials, EarlyView.
Novel type of rubrene microcrystals in the orthorhombic phase are grown exhibiting spatial contrast in spectra and dynamics due to differences in unit cell orientation. Distinct zones selectively host redshifted luminescence band at ≈650 nm driven by high photon absorption.

Ferroelectric Fluids for Nonlinear Photonics: Evaluation of Temperature Dependence of Second‐Order Susceptibilities

Advanced Optical Materials, EarlyView.
Nonlinear optical susceptibilities of five different materials that exhibit the ferroelectric nematic phase, as well as smectic A ferroelectric phase, are determined. The materials investigated include archetypal molecular architectures as well as mixtures showing room‐temperature ferroelectric phases.

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 ...
