Record Performance in Vertically Stacked, Solution‐Processed ZTO Schottky Diodes

open access: yesAdvanced Materials Technologies, EarlyView.
Schottky diodes based on solution processed sustainable zinc—tin–oxide thin films present an eco‐friendly and versatile alternative to conventional CMOS based technologies. Beyond state‐of‐the‐art performance for vertically stacked solution‐based oxide diodes was achieved, including rectification ratios exceeding nine orders of magnitude, and intrinsic

Tunable 3D‐Printed Static Mixers for Gradient Bioprinting With High Cell Viability

open access: yesAdvanced Materials Technologies, EarlyView.
ABSTRACT The fabrication of native tissue‐like structures with gradual transitions in material properties, cell types, and growth factors remains a major challenge in biofabrication due to the lack of suitable methods. Mimicking the hierarchical organization of living tissues is essential for functional models, yet creating gradient, multimaterial ...
