Solid–liquid phase change in planetary cores
Comptes Rendus. PhysiqueThe ubiquitous phenomena of crystallization and melting occur in various geophysical contexts across many spatial and temporal scales. In particular, they take place in the iron core of terrestrial planets and moons, profoundly influencing their dynamics

Advanced Science, EarlyView.A covalently integrated single‐component photocatalyst is constructed by anchoring selenoviologen to platinum nanoparticles via robust N‐heterocyclic carbene ligands. The resulting Pt─C covalent bonds function dually as protective structural scaffolds and direct channels for ultrafast intramolecular electron transfer This precise interfacial ...

Stochastic Entanglement of Deterministic Origami Tentacles For Robust Robotic Grasping
Advanced Science, EarlyView.This study introduces an origami tentacle gripper to robustly grasp objects‐in air, underwater, and even in orbital space‐by exploiting a synergy between local, deterministic deformation programming and global, stochastic entanglements. A single origami tentacle can be designed to coil with a simple tendon pull.

Oceanic and volcanic heat converge in a subglacial channel of the Kamb Ice Stream in West Antarctica
Communications Earth & EnvironmentMelting from oceanic heat and basal lubrication from subglacial freshwater are fundamental elements of the West Antarctic Ice Sheet mass balance that are poorly constrained. The ice streams feeding the Ross Ice Shelf grounding line periodically start and

Advanced Science, EarlyView.How can humanity achieve lunar self‐sufficiency? We utilize Au topology networks to modify the abundant lunar ilmenite. This catalyst, under sunlight, can convert waste carbon dioxide into space fuel. This design leverages the moon's natural vacuum for green manufacturing, avoiding the waste of gold and serving as “artificial chloroplasts” to sustain ...
