Degradable Magnetic Composites from Recycled NdFeB Magnets for Soft Actuation and Sensing

Advanced Robotics Research, EarlyView.
This work presents a degradable soft magnetic composite made from recycled NdFeB particles embedded in a gelatin‐based organogel. The material is processed into magnetic sensors and soft robotic components, which can later be dissolved in a green solvent to recover NdFeB magnetic particles.

A Rigid–Foldable Kirigami‐Inspired Metamorphic Mechanism With Programmable Motion Modes and Self‐Locking

Advanced Science, EarlyView.
Geometric constraint reconfiguration enables a rigid–foldable kirigami‐inspired mechanism to switch between twisting, directional translation, and self‐locking states. By encoding multifunctionality directly into its architecture, the mechanism achieves multimodal motion and passive locking without reassembly, providing a compact platform for adaptive ...

Synergistic Cu–Co Sites Enabled Reversible H2 Storage and Release in Liquid Organic Hydrogen Carriers

Angewandte Chemie, EarlyView.
One catalyst, two directions: reaction‐induced reconstruction converts copper‐cobalt‐ceria oxide (CuCoCeOx) into cooperative copper–cobalt oxide interfaces on oxygen‐deficient ceria (CeO2 − x). This self‐adaptive ensemble couples liquid organic hydrogen carrier (LOHC) adsorption and activation with reversible H2 cleavage and recombination, enabling ...
