Visible and Infrared Dual‐Band Camouflage Device Using Reflective Display Technology
Integrating electrochromic devices and electrophoretic display technologies has led to developing a flexible dual‐band camouflage device. The system enables adaptive modulation across visible and near‐infrared spectra through pixel‐level control, rapid switching, and bistable operation.

Excellent mobility is achieved in intrinsically stretchable, fine‐patterned organic thin‐film transistors (OTFTs) through well‐aligned molecular arrangements. Abstract Intrinsically stretchable organic transistors are promising solutions for realizing stretchable electronic systems, such as skin‐like wearables and next‐generation displays. Nevertheless,

Dielectric Barrier Discharge Electrothermal Heating and Additive Manufacturing of Thermoset Parts
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 ...

A sustainable approach is reported for upcycling PET waste into thermoplastic polyester elastomer (TPEE)‐based films with advanced properties, specifically designed for applications in strain sensing, conductivity, and photothermal response. Through a layer‐by‐layer deposition technique, TPEE films are fabricated with bio‐compatible chitosan (CH) or ...

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.

Advanced anodic aluminium oxide (AAO) nanostructures incorporate interconnections between the vertical pores, forming a 3D‐AAO nanonetwork that functions as a Bragg reflector. By varying the periodicity of the transverse channels, the light‐matter interaction can be tuneable to enhance their emissivity and passive radiative cooling performance across ...
