Two‐Step Thermal Upcycling of Flexible Printed Circuit Board Waste Into Metallic Copper Nanoparticles: Synthesis and Characterization

Advanced Materials Technologies, EarlyView.
A two‐step thermal upcycling process converts flexible printed circuit board waste into high‐purity copper nanoparticles using polymer degradation and arc discharge. The synthesized nanoparticles exhibit controlled morphology and high metal purity.

Parameter Investigation for Stamp Manufacturing of Complex 3D Geometries Using Nanoimprint Lithography

Advanced Materials Technologies, EarlyView.
Nanoimprint lithography can replicate complex 3D microstructures with undercuts using single‐layer polymer stamps of different elasticities. By combining experiments and simulations, T‐shaped geometries and suitable undercut radii were identified that minimize stress and defects during demolding.

Deciphering Haze Formation in Black Electrochromic Polymer Films

Advanced Optical Materials, EarlyView.
This study investigates haze in electrochromic polymer films at different stages, including pre‐treatment, post‐treatment, and after device operation. Haze varies with solution‐state aggregation, film morphology, and electrochemical doping, and is governed by morphological features such as surface roughness, micro‐porosity, crystallinity, aggregation ...

Transparent Single‐Dye NIR Photonic Platform for Multimodal Optical Authentication

Advanced Optical Materials, EarlyView.
A single‐component DHP‐SQ dye integrates visible transparency, near‐infrared (NIR) fluorescence, and photothermal functionality into one molecular platform. NIR‐selective visualization transforms visually imperceptible printed patterns into readily authenticated information, while screen‐printing compatibility enables well‐defined patterning on diverse
