New process allows 3D printing of microscale metallic parts

Engineers at Caltech have developed a method for 3D printing pure and multicomponent metals, at a resolution that is, in some cases, an order of magnitude smaller than previously possible. The process, which uses water-based ...

Cooler transformers could help electric grid

Most people do not give the U.S. electric grid a second thought—we flip a switch, and the lights come on. Behind the scenes are thousands of power plants and utilities linked by millions of miles of transmission lines. ...
