A University of California, Berkeley (www.berkeley.edu) team, headed by physics professor Alex Zetti, has built a 500 nm electric motor—the world's smallest—from carbon nanotubes and silicon. The motor is the first device that allows external wires and a rotor. In this case, the rotor is between 100 to 300 nm long, while the carbon nanotube shaft to which it is attached is only a few atoms across, perhaps 5 to 10 nm, the team says. Applications might include optical switching, or the spinning rotor could be used to mix liquids in microfluidic devices, the team adds.
Time was when sports equipment was made only from common, everyday, low-tech materials. But now sports equipment has a new, high-tech ingredient that is helping players take their game to the next level.
A humanoid diving robot has recovered treasure from the wreck of French King Louis XIV's flagship, untouched for nearly 400 years. The bot not only looks somewhat human-shaped, it's also got stereoscopic humanlike vision, artificial intelligence, and haptic force feedback.
Design collaboration now includes the entire value chain. From suppliers to customers, purchasing to outside experts, the collaborative design team includes internal and external groups. The design process now stretches across the globe in multiple software formats.
