Internal-combustion engines run on the explosive power of burning gasoline; electric motors, by contrast, run on magnetic flux. There are several ways to create and manipulate flux, thereby ...

Researchers have shown how spectroscopic measurements can be made much faster. By correlating polarization to the color of a pulsed laser, the team can track changes in the spectrum of the light by ...

The process of testing new solar cell technologies has traditionally been slow and costly, requiring multiple steps. Led by a fifth-year PhD student, a Johns Hopkins team has developed a machine ...

WASHINGTON — Researchers have developed a fast and energy-efficient laser-writing method for producing high-density nanostructures in silica glass. These tiny structures can be used for long-term five ...
