Covalent superconductor - Superconducting materials where the atoms are linked by covalent bonds. High-temperature superconductivity - Superconductive behavior at temperatures much higher than absolute zero. Room-temperature superconductor - Material which exhibits superconductivity above 0 °C A superconductor is an element or metallic alloy which, when cooled below a certain threshold temperature, the material dramatically loses all electrical resistance. In principle, superconductors can allow electrical current to flow without any energy loss (although, in practice, an ideal superconductor is very hard to produce) Superconducting Material Superconductors are materials which transport electric charge without resistance1 and with the display of associated macroscopic quantum phenomena such as persistent electrical currents and magnetic flux quantization. From: Advances in Quantum Chemistry, 201 A superconducting material is one that manifests the ability to conduct electrical energy without resistance or energy loss under certain conditions. This quality is called Superconductivity, and was discovered in 1911 by Heike Kamerlingh Onnes
The superconducting order parameter on different grains are connected by effective SNS (superconductor-metal-superconductor) Josephson junctions which, as suggested in ref. 22, can vary. Superconductivity Meaning Superconductivity meaning simply states that there is no resistance or almost zero resistance in the material or any object. A material or an object that shows such properties is known as a superconductor. The conductivity referred to here is the electrical conductivity of a material Surprisingly in 1986, Muller and Bednorz discovered high temperature superconductor in ceramics.

The first superconductor was mercury cooled to a temperatures of 4°K. Applications. Superconductors already have practical applications, since refrigeration of materials down to the boiling point of liquid helium or hydrogen is feasible, though very expensive This results in the field penetrating both materials. Both samples are then cooled so that the ideal conductor now has zero resistance. It is found that the superconductor expels the magnetic field from inside it, while the ideal conductor maintains its interior field. Note that energy is needed by the superconductor to expel the magnetic field Scientists have discovered that a two graphene layers can conduct electrons showing superconductivity if the two hexagonal nets are twisted against each other at a 1.1 degree angle.
