Superconductivity is an advantageous property observed in some materials, which entails an electrical resistance of zero at extremely low temperatures. Superconductors, materials that exhibit this ...

For the first time, researchers in China have demonstrated a high-temperature superconducting diode effect, which allows a supercurrent to flow in both directions. Published in Nature Physics, the ...

PROVIDENCE, R.I. [Brown University] — Superconductors — materials that conduct electricity with zero loss of energy — have been well-understood since the development of what’s called the BCS theory in ...

A diode is a device that allows electric current to flow in only one direction, from its anode towards its cathode but not the other way around. There is plenty of online material explaining diode ...

The diode is one of the most commonly adopted and simply made elementary component in semiconductor technology. It’s been the basic starting brick for the construction of all electronic technology, ...

REVIEW – EM-Smart has recently announced their newest laser engraver, the EM-Smart Dual Desktop Laser Engraver. I’m always interested in reviewing lasers, but much more than that, I’m always ...

Hamamatsu Photonics has achieved what it calls “world-class” quasi-continuous wave output of 2.0 kW from a 1 cm-wide laser diode (LD) bar at room temperature. Quasi-continuous wave (QCW) is a mode of ...
