First, the cooling mechanism is based on the use of aluminium electrodes, which become superconducting below 1.2 K. The superconducting energy gap acts as an efficient energy filter for electrons ...

Metals with fewer free electrons, like lead or tin, have higher resistance so do not conduct as well. Figure caption, Aluminium is a good electrical conductor because it has many free electrons ...

Relativistic electrons in the outer Van Allen belt wreak havoc with satellites in geosynchronous orbit, but how they reach such high energies has been unclear. New data identify gyro-resonant wave ...

The aluminium foil trick is straightforward ... which causes individual items to rub against each other and exchange electrons. This causes some fabrics to become positively charged and others ...

However, when it comes to atoms’ third component, electrons, the answer is not as easy. That’s because, as far as we know, electrons are fundamental particles. In other words, they have no ...
