Aerotech's ABRS series rotary air-bearing stages provide superior angular positioning, velocity stability and error motion performance in an exceptionally low-profile package. The stages have been optimized to minimize stage height and its low profile reduces the effective working height of the system while minimizing "stack-up" related errors. A clear aperture can be used for product feed-through, laser beam delivery, cable clearance or application-specific requirements. Large air-bearing surfaces provide high stiffness and load capacity, producing excellent axial and radial error motions, and tilt error motion as well. The resulting face error motion is a benefit for applications requiring exceptional planar performance.
For decades, engineers have worked to combat erosion by developing high-strength alloys, composites, and surface coatings. However, in a new paper, a team at Jilin University in China turned to one of the most deadly animals in the world for inspiration -- the yellow fat-backed scorpion.
Green energy is being billed as a way to make communities that are energy deprived more self-sustaining. So it makes sense to use natural materials to create devices that harvest this type of energy. That’s the idea behind a hybrid wind/solar energy harvester made of bamboo that’s been developed by UVM researchers.
