It is a common practice to lockout and/or tagout control devices. In a nuclear power plant’s control room with its many analog controls, you might (for example) see red covers over specific switches.

A new low-power technique for detecting the spin of electrons in a non-magnetic system could aid the development of spintronics devices that work using ferroelectricity rather than ferromagnetism.

Controlling magnetic states in materials typically requires continuous power or only works in rare, specialized systems. Researchers developed a general theory showing how electric fields can ...

(NEW YORK) -- TASERS, also called "electrical control devices," have been used by law enforcement since the mid-1970s, with the intention to help subdue resistant suspects without physical contact or ...

Fleeting electron-hole pairs are giving scientists a new window into optimizing light-emitting devices (LEDs). Using quantum magnetic resonance, Osaka Metropolitan University researchers have ...
