Advanced Materials, EarlyView.Inspired by the octopus and the golden wheel spider, soft robots with liquid crystal elastomer arc fibers as appendages are fabricated to transcend surface constraints through an elevated center of mass and minimal contact footprints. By leveraging curvature‐encoded deformation‐recovery cycles, these robots exhibit contractile, torsional, and flexural ...

A Crystalline and Thermally Stable Selenocysteine Selenenic Acid
Angewandte Chemie, EarlyView.The long‐sought catalytic intermediate of selenoproteins, selenocysteine selenenic acid (Sec–SeOH), is isolated for the first time at ambient temperature. A bioinspired selenopeptide sequence encapsulated within a protective molecular cradle and an oxidant‐free route from selenenyl iodide (Sec–SeI) enable the isolation of Sec–SeOH. Contrary to the long‐

Advanced Robotics Research, EarlyView.A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...

Advanced Science, EarlyView.A physics‐based framework resolving graphite phase‐separation dynamics establishes a predictive, degradation‐aware fast‐charging methodology for commercial Li‐ion batteries. The resulting model‐informed protocol achieves 20%–80% state‐of‐charge in 14 min while matching the long‐term degradation of a commercial 25‐minute EV strategy.
