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.

Additive Manufacturing of Ni‐Based Thermoelectric Materials for Waste Heat Recovery

Advanced Materials Technologies, EarlyView.
Thermoelectric generators convert waste heat into electricity but are constrained by conventional fabrication. Here, laser powder bed fusion enables direct printing of customised n‐type Cu60Ni40 and p‐type Ni90Cr10 legs. The assembled module achieves 0.8% efficiency at ΔT = 419 K, demonstrating scalable additive manufacturing of eco‐friendly, design ...

Highly Efficient Pure‐Blue Single‐Layer Organic Light‐Emitting Diodes Without High‐Triplet‐Energy Auxiliary Materials

Advanced Optical Materials, EarlyView.
Blue organic light‐emitting diodes (OLEDs) comprising triplet‐harvesting emitters require the use of high‐triplet‐energy hosts and blocking layers to confine the triplet excitons to the emitter. Here, we present efficient single‐layer blue hyperfluorescent OLEDs comprising solely of a matrix‐free emissive layer between two charge‐injecting electrodes ...

Projector‐Induced Waveguide Encoded Lattices (ProWELs) with Optical Functionality: From Enhanced Fields of View (FOV) to 3D Data Encoding

Advanced Optical Materials, EarlyView.
We describe the fabrication of 3D polymeric waveguide architectures with tunability of waveguide diameter, lattice symmetry and long and short‐range order using an inexpensive (< $400 CAD) digital light projector. We demonstrate that Projector induced Waveguide Encoded Lattices (ProWELs) possess advanced functionality including tuneable Fields of View (

Simultaneous Measurement of Thermal Expansion and Thermo‐Optic Effect in Solids Using Terahertz Spectroscopy

Advanced Optical Materials, EarlyView.
Thermal expansion and the thermo‐optic effect in solids are closely coupled, reflecting concurrent changes in mass density and polarizability. Using echo‐resolved THz spectroscopy, we simultaneously determine sub‐micrometer thermal expansion and complex refractive index changes of MgO and Al2O3 from 10–325 K. The analysis yields both the coefficient of

Strong Plasmon–Exciton Coupling Tuned by Corner Etching of Gold Nanocubes and Nanotriangles

Advanced Optical Materials, EarlyView.
Systematic etching of gold nanocubes (AuNCs) and nanotriangles (AuNTs) reveals how nanoparticle morphology governs plasmon–exciton strong coupling. While rounding the corners of AuNCs weakens their coupling, triangular geometries robustly preserve deep strong coupling.
