Three‐Dimensional Printed Microarchitected Hierarchically Porous Biodegradable PLA/S/CNT Nanocomposite Electrodes for High‐Performance Lithium–Sulfur Batteries

Advanced Materials Technologies, EarlyView.
Hierarchically microarchitected PLA/S/CNT cathodes are fabricated via scalable fused filament 3D printing as high‐sulfur‐loading hosts for rechargeable lithium–sulfur batteries. The assembled Li–S cells with sulfur loadings up to 17 mg cm−2 deliver an areal capacity of 9.2 mAh cm−2 and retain 96% of their discharge capacity after 100 charge–discharge ...

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures

Advanced Robotics Research, EarlyView.
Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.
