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

Millifluidic Synthesis of Core–Shell Resonators For Tunable Sonic BandGaps in Acoustic Metamaterials
Advanced Materials Interfaces, EarlyView.Millimeter‐scale core–shell acoustic resonators are fabricated by a gravity‐assisted dripping approach and incorporated into epoxy composites at controlled volume fractions. The resulting alumina–core resonator composites show tunable low‐frequency acoustic attenuation, demonstrating a scalable route for integrating locally resonant metamaterial units ...
