From Folding Mechanics to Robotic Function: A Unified Modeling Framework for Compliant Origami

Advanced Science, EarlyView.
A geometry‐consistent DDG framework captures compliant origami deformation from rigid‐like folding to soft panel bending. By tuning crease and panel stiffness, bistable snap‐through responses transform into smooth monostable deformation, enabling programmable stability and robot‐scale locomotion.

Unraveling Hierarchical B‐Site Ordering: Mechanism of Microwave Dielectric Enhancement in Complex Perovskite Oxide Ceramics

Advanced Science, EarlyView.
This study maps out the hierarchical ordering in 1:2 B‐site complex perovskite ceramics using a comprehensive multiscale characterization route. It turns out that intradomain strain, oxygen vacancies, and Mg disorder within the ordered domains act as strong phonon scatterers.
