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.
In a move that strengthens its 3D design business, Stratasys continued a 15-month buying spree this week by announcing its plan to acquire GrabCAD, a provider of a cloud-based collaboration environment for engineers.
Many diverse markets take advantage of semiconductor IP; so many that no one can recite the entire list without leaving off several. So why do we track all the vertical markets? They all have a unique set of requirements and value attributes differently. One major vertical market segment is automotive.
