Snap and Jump: How Elastic Shells Pop Out
Advanced Robotics Research, EarlyView.Indent an elastomeric shell and let it go. The spherical shells can store and release the elastic energy. Desktop‐scale experiments, material point method simulation, and analytical theory uncover the fundamental mechanism of soft jumping robots.

Minor satellites and the Gaspra encounter [PDF]
Observational evidence, especially from occultations and radar, indicate that satellites of minor planets are numerous and commonplace. This leads to the prediction that the Galileo spacecraft will find many such 'minor satellites' at the upcoming close ...

p‐Cu(OH)2/n‐SrTiO3 Heterojunction for Efficient Photocatalytic Hydrogen Production
Advanced Sustainable Systems, EarlyView.Improving the efficiency of photocatalysts in the hydrogen evolution reaction relies on developing cost‐effective co‐catalysts. This study focuses on p‐Cu(OH)2/n‐SrTiO3 heterojunctions for efficient hydrogen production. 1 wt.% Cu‐based co‐catalyst significantly enhances performance, achieving ≈3.5 times higher hydrogen production compared to pristine ...

The growth of planets by pebble accretion in evolving protoplanetary discs
, 2015 The formation of planets depends on the underlying protoplanetary disc structure, which influences both the accretion and migration rates of embedded planets. The disc itself evolves on time-scales of several Myr during which both temperature and density

Advanced Sustainable Systems, EarlyView.A zero‐waste, eco‐friendly, binder‐free, scalable, rapid, and one‐pot laser carbonization approach fabricates a coppercuprous oxide/carbon electrocatalyst derived from HKUST‐1 metal‐organic framework for efficient nitrate reduction to ammonia. The catalyst exhibits high ammonia yield, excellent Faradaic efficiency, and robust stability.
