Advanced Materials, EarlyView.Ordered three‐dimensional anodic aluminum oxide (3D‐AAO) nanoarchitectures with longitudinal and transverse pores enable architecture‐driven metamaterials. The review maps fabrication advances, including hybrid pulse anodization, and shows how 3D‐AAO templates tailor properties across magnetism, energy, catalysis, and sensing.

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization
Advanced Materials Interfaces, EarlyView.Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

Advanced Materials Technologies, EarlyView.Roll‐to‐roll direct‐current sputtering enables room‐temperature manufacture of flexible bismuth telluride thermoelectric films. By identifying a low‐power deposition window that suppresses charge‐induced arcing, this work links sputtering conditions to film structure, charge transport, and thermoelectric performance, achieving a room‐temperature figure
