What is Superconductivity definition/concept

Certain materials have a unique property in that they conduct electricity without resistance. Materials with this characteristic are known as superconductors. Superconductivity

A conventional electricity cable allows normal electricity conduction, as an electrical force introduced at one end of the cable would exit at the other end.

Basically, electrons move and this causes electrical current to travel from one end to the other. However, in this type of situation, part of the energy is lost, since the material’s resistance prevents the passage of electrons. This loss of energy in normal conductors is due to a phenomenon known as Joule’s law. Superconductivity

Graphene allows the electrical current to be carried without loss of energy

One of these materials is graphene. It has unique physical properties as they are not found in other materials. In the first place , this embodiment allows to create carbon thin blades. On the other hand, it is extremely hard, light and flexible. Due to its properties theoretical physicists have proven that it is capable of conducting electrons without generating resistance and for this reason it is a superconductor.

Superconductivity could revolutionize all energy-related industries

Transportation systems, medical devices and power transmission in general could change in the coming years with new materials such as graphene.

Conventional superconductivity occurs with some metals that are cooled to temperatures that reach absolute zero . This principle is used in some technologies, such as high-speed trains, MRI scanners, and high-resolution electron microscopes.

A phenomenon discovered just over 100 years ago

Superconductivity is based on two basic properties: zero resistance and magnetic field  expulsion . This discovery was made by the Dutch physicist Heike Kamerlingh Onnes, in 1911, after working with materials at low temperatures. In 1913, his investigations received the Nobel Prize in Physics. It was the first step towards discovering other superconducting materials, such as niobium nitride, silicon, vanadium and the aforementioned graphene.

The tunnel effect  explained by  quantum physics is one of the new advances related to superconductivity. This phenomenon of nature is associated with the processes in which electrons interact in the transmission of energy.

It is stated that the applications of the tunnel effect  could make it possible to overcome energy barriers that have not been overcome so far.
