A Roadmap for Plasma‐Enabled Electrocatalysis in Urea Production

open access: yesAdvanced Materials, EarlyView.
A modular plasma—electrochemical platform enables fully electrified urea synthesis from air and CO2 under ambient conditions. This Review integrates plasma oxidation, C─N coupling electrolysis, mechanistic insights, and techno‐economic metrics into a roadmap for scalable, distributed, and renewable fertilizer production.

Orientation Control in Epitaxial PdO Thin Films Grown on MgO (001) – Role of Oxygen Chemical Potential

open access: yesAdvanced Materials Interfaces, EarlyView.
Crystal orientation of thin films is closely linked to their strain states, electronic properties, and surface chemical reactivity of functional materials. Therefore, understanding the mechanisms that govern orientation control is essential for materials design and synthesis.

Manipulating the Chiral Self‐Assembly of Achiral Porphyrin Molecules with Carbon Nanotubes as Templates

open access: yesAdvanced Materials Interfaces, EarlyView.
A chiral self‐assembly of achiral porphyrin molecules is presented on the surfaces of achiral carbon nanotubes, and the obvious optical activity is observed as direct and solid spectroscopic evidence. The findings provide an effective carbon nanotube‐templated strategy for inducing and manipulating the chiral self‐assembly of porphyrin and other chiral/

High Aspect Ratio, Superconducting Vacuum Gap Capacitor NEMS with Plate Distances Down to 32 nm

open access: yesAdvanced Materials Technologies, EarlyView.
Fabrication of aluminium vacuum gap capacitor based NEMS is investigated with a free to move top electrode. To avoid collapse of the top electrode vertical stress gradient is controlled through sputter parameters. The result is wafer‐level high‐yield fabrication of vacuum gap capacitors with radii between 7 µm and 30 µm and integrated piezoactuators. A

Development of a Miniaturized Capillary Rheometer for High Shear Rate Rheology of Dense Suspensions

open access: yesAdvanced Materials Technologies, EarlyView.
This research presents a downscaled benchtop, low‐cost capillary rheometer that can characterize high shear rate rheometry of dense suspensions. The device is capable of measuring across a wide range of applicable shear rates using only a limited quantity of material and addresses a need for an accurate and affordable capillary rheometer.
