Microneedles Fabrication by Substrate‐Independent Electrostretching and In‐Situ Focused Electrospray Deposition for Transdermal Drug Delivery

open access: yesAdvanced Materials Technologies, EarlyView.
A novel electrohydrodynamic platform integrating substrate‐independent in situ dried electrostretching (SI‐PIDES) and in situ focused electrospray deposition (IFED) enables mold‐free fabrication and precise drug coating of flexible core–sheath microneedle patches.

Single‐Step Fabrication of Smart 3D Microstructures Exploiting Naphthopyrans as Photoinitiators and Photochromic Molecules

open access: yesAdvanced Optical Materials, EarlyView.
Naphthopyran–benzophenone compounds can act simultaneously as photoinitiators and photochromic molecules for two‐photon polymerization. Using a single‐step process, liquid photoresist is encapsulated within polymerized 3D microstructures, preserving reversible UV–vis photochromism after fabrication.

Residual Tetramethylammonium Hydroxide Limits ZnO Nanoparticle‐Based Quantum Dot Light‐Emitting Diode Performance

open access: yesAdvanced Optical Materials, EarlyView.
Residual tetramethylammonium hydroxide (TMAH) from ZnO nanoparticle (NP) synthesis is uncovered as a hidden impurity that migrates into quantum dot emissive layers during thermal processing. The resulting exciton quenching reduces the efficiency of quantum dot light‐emitting diodes despite improved electron transport upon annealing.
