Squid is an acronym for Superconducting Quantum Interference Device, a method developed to detect tiny fluctuations in magnetic fields using a superconductor cooled by liquid helium.
And superconductive material is the opposite of an insulator: an insulator stops electricity, but a superconductor will allow electricity to flow freely through them.
Currently, so-called high-temperature superconductors must be cooled with liquid nitrogen to at least - 225F.
Unfortunately, the predictions were overly optimistic and there are many inherent problems that must be overcome before the full potential of ceramic superconductors is realized.
A computational search is well under way for superconductors with higher critical temperatures than substances already found in the laboratory.
These superconductors usually contain more oxygen atoms than predicted by valence theory.
Why certain ceramic compounds become superconductors at relatively high temperatures still baffles the world's physicists.
