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 ...

3D Printed Meter‐Scale Soft Origami Robots Capable of Load‐Bearing Actuation Via Crease Stiffness Modulation

Advanced Science, EarlyView.
Origami has inspired numerous soft deployable mechanisms for safe human‐robot interaction, while its intrinsic kinematic instability at arbitrary configurations limited their practical robotic application. This work presents a 3D printed meter‐scale origami robotic actuator capable of load‐bearing deformation through creaseline stiffness modulation.

Supercapacitor Safety: Overcharge‐Induced Failure Mechanisms in Electrochemical Double‐Layer Capacitors

Advanced Science, EarlyView.
Time‐resolved synchrotron radiography reveals the internal evolution of electrochemical double‐layer capacitors under abusive overcharge. EDLCs are shown to follow a thermally driven failure pathway involving electrolyte decomposition, gas generation, and structural collapse, distinct from chemically driven thermal runaway effects of Lithium‐ion ...

In Situ CO2‐Induced Hydrogels for Enhancing Carbon Sequestration in Saline Aquifers

Advanced Science, EarlyView.
A novel integrated method that combines in situ CO2‐induced phase‐transition hydrogels formed by a C22‐tailed tertiary amine dispersion with tailored deep eutectic solvents to increase CO2 sequestration in saline aquifers. ABSTRACT Carbon sequestration in saline aquifers underpins global net‑zero emission goals, yet existing CO2 storage capacity ...
