Electric (plasma) propulsion devices have been used for applications such as station-keeping and orbit transfer, in place of chemical rockets, because they provide a higher specific impulse. Detailed ...

Standard electronic devices encode bits of information by controlling the amount of electric charge in the circuits. Alternatively, it is possible to make devices that rely on other properties of ...

Electrons may not be the only movers and shakers among subatomic particles, but they do power the modern world. How much work do they actually do, and how fast are they? The answer is more complicated ...

A team of physicists at the SLAC National Accelerator Laboratory, in Menlo Park, California, generated the highest-current, ...
