  2. Electron paramagnetic resonance - Wikipedia

    en.wikipedia.org/.../Electron_paramagnetic_resonance

    Electron paramagnetic resonance (EPR) or electron spin resonance (ESR) spectroscopy is a method for studying materials that have unpaired electrons. The basic concepts of EPR are analogous to those of nuclear magnetic resonance (NMR), but the spins excited are those of the electrons instead of the atomic nuclei. EPR spectroscopy is particularly ...

  6. Pulsed electron paramagnetic resonance - Wikipedia

    en.wikipedia.org/wiki/Pulsed_electron...

    Pulsed electron paramagnetic resonance (EPR) is an electron paramagnetic resonance technique that involves the alignment of the net magnetization vector of the electron spins in a constant magnetic field. This alignment is perturbed by applying a short oscillating field, usually a microwave pulse.

  7. Circuit breaker - Wikipedia

    en.wikipedia.org/wiki/Circuit_breaker

    A circuit breaker is an electrical safety device designed to protect an electrical circuit from damage caused by current in excess of that which the equipment can safely carry (overcurrent). Its basic function is to interrupt current flow to protect equipment and to prevent fire.

  8. ANSI device numbers - Wikipedia

    en.wikipedia.org/wiki/ANSI_device_numbers

    In electric power systems and industrial automation, ANSI Device Numbers can be used to identify equipment and devices in a system such as relays, circuit breakers, or instruments. The device numbers are enumerated in ANSI / IEEE Standard C37.2 Standard for Electrical Power System Device Function Numbers, Acronyms, and Contact Designations .

  9. Electron spectrometer - Wikipedia

    en.wikipedia.org/wiki/Electron_spectrometer

    An electron spectrometer is a device used to perform different forms of electron spectroscopy and electron microscopy. This requires analyzing the energy of an incoming beam of electrons. Most electron spectrometers use a hemispherical electron energy analyzer in which the beam of electrons is bent with electric or magnetic fields. Higher ...
