Superconductors are certain metals or alloys that can conduct electricity without resistance. However, this happens when the temperatures are very low, just a little above the Kelvin temperature of – 273 degree centigrade. Superconductors are used in operations such as levitating trains and MRI machines.

Researchers are after superconductors which are capable of superconductivity at room temperatures. That can lead us to more powerful computers.

David Pines, the theoretical physicist was studying the metal strontium ruthensate. He predicted in 1956 a demon particle. Seventy years later after this was predicted, researchers at the University of Illinois recently discovered a demon particle that could lead to the making of superconductors that can operate at room temperature.

The demon particles do not have mass, and so they can blend with any energy at room temperature. The experiment was not specifically related to superconductors. They were studying metals similar to high temperature superconductors. They studied electronic properties of the metal by blasting it with electrons. That led to the discovery of the demon.

Demons are not mainstream. They took sometime to realise that they have found the demon.
