Mass-producible hydrophobic perfluoroalkoxy/nano-silver coatings by suspension flame spraying for antifouling and drag reduction applications

, 2017
To exploit marine metal materials with antifouling and drag reduction properties, we constructed hydrophobic perfluoroalkoxy (PFA)/nano silver (Ag) coatings onto aluminum substrates by suspension flame spray deposition of PFA/AgNO3 composites.

Nonlocomotory Robotic Strategies for Dynamic Rotation Control in Terrestrial Robots: A Review

Advanced Robotics Research, EarlyView.
Terrestrial robots increasingly require rapid body rotation to maintain stability and agility in complex environments. This review shows nonlocomotory rotational control strategies that operate without ground contact, including reaction wheels, tails, bars, limbs, and thrusters.
