High‐Pressure Homogenization: An Industrially Scalable Method for Producing PHBH Powders for Selective Laser Sintering

open access: yesAdvanced Materials Technologies, EarlyView.
This article investigates a sustainable approach to producing new powders for selective laser sintering by using high‐pressure homogenization to micronize biopolymers. The approach yields flowable, thermally stable particles with sub‐rounded morphology, enabling 3D printing of dense components with complex geometries.

Miniaturized Devices for On‐the‐Spot Generation of Small‐Diameter Vascular Grafts

open access: yesAdvanced Materials Technologies, EarlyView.
An intracorporeal extrusion device is developed for on‐the‐spot generation of vascular grafts with tunable diameters spanning from 1 to 6 mm. The device uses biomimetic polymers and light, to promptly obtaining biocompatible and high‐burst pressure‐resistant grafts.

Enhanced Performance of Inkjet Printed Red Quantum Dot Light‐Emitting Diodes Influenced by ETL Uniformity with Solvent Systems

open access: yesAdvanced Optical Materials, EarlyView.
This study investigates the impact of solvent systems on the uniformity of the ZnO electron transport layer (ETL) in inkjet‐printed electroluminescent quantum dot (EL‐QD) devices. The mixed‐solvent approach effectively suppresses the coffee‐ring effect, enhances charge injection, and improves luminance, ultimately contributing to the optimization of EL‐

Mechanoluminescence of Bi‐Activated NaYGeO4 Polycrystals and 3D Printed Scaffolds in the NUV/Blue and NIR Spectral Range

open access: yesAdvanced Optical Materials, EarlyView.
NUV/Blue and NIR emitting mechanoluminescent (ML) materials based on a Bi‐doped germanate compound (NYGOBx) are reported. 3D‐printing is used to fabricate complex scaffold devices from this material, suggested for use as mechanically‐activated light sources for functional illumination.

Enhanced Stability of Cd‐Free Quantum Dot Light‐Emitting Diodes via Yttrium Acetate‐Modified ZnMgO: Suppressing Mg Migration

open access: yesAdvanced Optical Materials, EarlyView.
A surface passivation strategy using yttrium acetate to suppress Mg ion migration from the ZnMgO electron transport layer is proposed. This treatment restores oxygen vacancies on the ZnMgO surface, enhancing device stability. The Cd‐free quantum dot light‐emitting diodes demonstrate a 65.5% increase in operational lifetime with an external quantum ...
