Comparison of Type – I and Type – II Superconductors

Based on the behavior and properties of Superconductors , these are classified into two categories- (1) Type – I Superconductors: Low Temperature Superconductors. (2) Type – II Superconductors: High Temperature Superconductors. td{ width:49% } Type – I and Type – II superconductors slightly differen

Meissner Effect and Application of Meissner Effect

When Superconductors , are cooled below the critical temperature, they expel magnetic field and do not allow the magnetic field to penetrate inside them. This phenomenon in superconductors is called Meissner effect . This phenomenon was discovered by German physicists “Walther Meissner” and “Robert

Chemical Properties of Engineering Materials

Being an Engineer it is important to have the knowledge of chemical properties of engineering materials. Because most the engineering materials come into contact with other materials and react chemically to each other. Due to this chemical reaction they may suffer from chemical deterioration. Some o

Free Electron Theory of Metals

The metals form a unique type of bonding known as metallic bonding and form the lattice structure. The uniqueness in such a type of bonding fashion lies in the fact that unlike ionic bonding and covalent bonding where the sharing of electrons is between two atoms and the electrons remain localized,

Antiferroelectricity

This is a physical property associated with antiferroelectric materials. Actually, these are materials having ions which can polarize without external field (spontaneous polarization). As a result, dipoles are ordered or arranged with alternating orientation. That is, adjacent lines will be in anti

pH Measurement

Partial pressures of hydrogen, carbon dioxide and oxygen are measured with blood gas analyzers. They determine the acid base balance in the body. When pH value goes below 7.35 it indicates respiratory acidosis and respiratory failure. It can be corrected using ventilator. At the same time when pH in
