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 Robotics Research, EarlyView.Here, we present a textile, wearable capacitive interface enabling multidirectional remote control by dynamically modulating electrode overlap and spacing via a freely gliding upper electrode. A forearm‐mounted prototype drives robotic and media tasks with 12–15 ms latency, maintains < 0.8% drift after 500 cycles, and remains stably functional at 90 ...

Advanced Science, EarlyView.Under normal conditions, MACF1 interacts with Rab14 and facilitates KIF16B‐mediated FGFR vesicle trafficking along microtubules to the plasma membrane, thereby supporting BMSC differentiation. In contrast, chronic GC exposure suppresses MACF1 expression, disrupting this transport and causing intracellular FGFR retention, which blunts osteogenic ...
