A highly stretchable fibrous actuator with robust cyclic actuation and reprogrammable motions

InfoMat, EarlyView.
We developed a stretchable fibrous actuator combining shape memory alloys and elastomers. It achieves 120% stretchability, 32% actuation strain, and output forces up to 4.3 N. The actuator demonstrates robust reversibility and reprogrammable motions, which enable applications such as a fibrous robot for pipe navigation, a wearable exoskeleton, and an ...

Vacancy-tuned paramagnetic/ferromagnetic martensitic transformation in Mn-poor Mn_{1-x}CoGe alloys

, 2010
It is shown that a temperature window between the Curie temperatures of martensite and austenite phases around the room temperature can be obtained by a vacancy-tuning strategy in Mn-poor Mn1-xCoGe alloys (0

Single‐Pulse Nanomorphology Governs Laser‐Induced Periodic Surface Structure Formation on Metals

Laser &Photonics Reviews, EarlyView.
Ultrashort pulse ablation enables generation of self‐organized periodic structures, where evolving nanomorphology controls pulse‐to‐pulse feedback. In noble metals, nanospikes form after the first pulse and localize surface waves, preventing periodic field distributions and thus suppressing their formation.
