The scale matters: A review on stimuli‐responsive microrobots categorized by scale for biomedical applications

Responsive Materials, EarlyView.
We systematically summarize how each scale dictates fundamental choices in design feature, manufacturing technology, driving mechanism, and control strategy, which are inherently governed by scale‐dominated physical principles. Furthermore, the application of scale‐determined operation modes of microrobots across different stages of medical ...

HWTS 50 Tool Steel Tailored for Laser Powder Bed Fusion: Sliding Wear of Bare Surfaces and Nitriding Response in Comparison with 18Ni300 and AISI H13

steel research international, EarlyView.
This work investigates the wear resistance and nitriding behavior of PBF‐LB/M‐processed Osprey HWTS 50, a lean hot work tool steel. Three heat treatment conditions are compared to conventional wrought H13, H11, and PBF‐LB/M 18Ni300. The study highlights HWTS 50's enhanced nitrogen diffusion, deeper nitriding hardness depth, and comparable or improved ...
