Dielectric Barrier Discharge Electrothermal Heating and Additive Manufacturing of Thermoset Parts

open access: yesAdvanced Materials Technologies, EarlyView.
3D printing of thermosets is difficult due to the low yield stress of most uncured resins. However, by locally heating resin using a non‐equilibrium plasma, layers can be partially cured and printing enabled. Plasma application to a liquid epoxy/carbon nanotube composite is observed to cause rapid surface heating and oxidation of the cured layers ...

High Photoluminescence Quantum Yield and Tunable Luminescence Lifetimes in the Sub‐Second Range of CaS:Eu2+ Phosphors for Tracer Based Sorting

open access: yesAdvanced Materials Technologies, EarlyView.
Efficient plastic waste sorting is crucial for circularity. Advanced methods using lanthanide photonic tracers enhance recycling beyond near‐infrared sorting. Europium(II)‐doped phosphors, with high stability and long luminescence decay, improve tracer detection in sorting systems, enabling precise identification of different plastic materials ...

Hygromnemics: Programmable Material Memory Matter Actuators via Wet Pre‐Constraining

open access: yesAdvanced Materials Technologies, EarlyView.
Humidity‐based pre‐constraining creates hygromnemics‐shape memory matter. From identical biocomposites actuation in dry and wet states is obtained via hygromnemic and hygromorphic actuation, respectively. Hygromnemic actuators present long‐ and short‐term shape memory abilities.

Lightweight and High‐Performance Ankle Braces Enabled by 3D Printed Metamaterial Liquid Crystal Polymer

open access: yesAdvanced Materials Technologies, EarlyView.
A flexible, lightweight ankle brace made from 3D‐printed liquid crystal polymer metamaterials offers targeted support without restricting movement. Programmable stiffness provides protection during risky motions. Biomechanical tests suggest performance comparable to commercial braces with reduced bulk, highlighting potential for broader orthotic ...

An Ultra‐Sub‐Wavelength Microwave Polarization Switching Antenna for Covert Communication Implemented With Directed Surface Acoustic Waves in an Artificial Multiferroic Magnonic Crystal

open access: yesAdvanced Materials Technologies, EarlyView.
A surface acoustic wave (SAW) launched in a two‐dimensional periodic array of magnetostrctive nanomagnets on a piezoelectric substrate excites spin waves in the nanomagnets which radiate electromagnetic waves in space. The polarization of the emitted beam in particular directions and at particular frequencies can be switched between horizontal and ...

Multi‐Level Hybrid Anti‐Counterfeit Labels via Solid‐State Dewetting Under Spatial Confinement

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents a hybrid encoding approach combining deterministic patterns fabricated by photolithography and stochastic features formed by the solid‐state dewetting of silver films under strong confinement at the micrometer and nanometer length scales.
