Ultrafast switch for superconductors

(PhysOrg.com) -- A high-temperature superconductor can now be switched on and off within a trillionth of a second – 100 years after the discovery of superconductivity and 25 years after the first high-temperature superconductor ...

Electron vortices in graphene detected for the first time

When an ordinary electrical conductor—such as a metal wire—is connected to a battery, the electrons in the conductor are accelerated by the electric field created by the battery. While moving, electrons frequently collide ...

New sensor for measuring electric field strength

Accurately measuring electric fields is important in a variety of applications, such as weather forecasting, process control on industrial machinery, or ensuring the safety of people working on high-voltage power lines. Yet ...

Unexpected quantum effects in natural double-layer graphene

An international research team led by the University of Göttingen has detected novel quantum effects in high-precision studies of natural double-layer graphene and has interpreted them together with the University of Texas ...

Magnetic materials for motors of the future

According to a statistic from the University of Chicago, 50 percent of U.S. power goes through a motor. Vehicles like cars and planes rely on motors to transform power, as do household appliances like vacuums and refrigerators. ...
