Numerical study of full penetration single- and double-sided U-rib welding in orthotropic bridge decks

Case Studies in Construction Materials
Under the repeated action of residual stress and wheel load caused by welding, fatigue cracks easily occur on the top plate-U rib welding of an orthotropic bridge deck (OBD). These affect the service life.

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.

Thermochemical Core–Shell Architecturing of Si‐SWCNT Composites for High‐Performance Li‐Ion Battery Anodes

Advanced Science, EarlyView.
A thermochemically engineered core–shell Si architecture is developed through the controlled evolution of a SWCNT‐coated Mg2Si precursor. The process simultaneously generates a nanoporous Si shell for strain accommodation and Li+ transport, a chemically anchored SiC interfacial layer for robust mechanical and electrical coupling, and a Mg‐containing Si
