Thanks to nanostructures that scatter and channel light, University of California, San Diego electrical engineers are working toward thin-film “single junction” solar cells with the potential for nearly 45 percent sunlight-to-electricity conversion efficiencies. This effort to break the theoretical limit of 31 percent efficiency ...

In a “major step” toward a practical energy source for powering tomorrow’s nanomachines, researchers at Arizona State University’s Biodesign Institute report the development of a new generation of tiny nanomotors that are up to 10 times more powerful than existing motors. Just like weekend hot-rodders who tinker with ...
