1 · Superconductivity 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. When the electrical conductivity is to the full potential facing

Energy storage is constantly a substantial issue in various sectors involving resources, technology, and environmental conservation. This book chapter comprises a thorough coverage of properties, synthetic protocols, and energy storage applications of superconducting materials.
Superconductors like other solids cannot relax instantaneously from excited states to thermodynamic equilibrium. In this paper, relaxation from thermal excitations is investigated, like after absorption of radiation or, under conductor movement, release and transformation of mechanical tension to thermal energy. Relaxation
This strongly suggests a close relationship between the pseudogap and superconductivity. Taking the entropy conservation into account, we argue that the ground state of the pseudogap phase should have Fermi arcs with finite density of states at 0 K, and the transport data show that it behaves like an insulator due to probably weak localization.

With high penetration of renewable energy sources (RESs) in modern power systems, system frequency becomes more prone to fluctuation as RESs do not naturally have inertial properties.
