Type II superconductors

Types of Superconductors – Pedagogy Zone

Physics /

Based on the value of superconducting transition temperature, superconductors are divided into two categories: (i) Low temperature superconductors (ii) High temperature superconductors S.No Low Temperature superconductor High Temperature superconductor 1. Superconductors having low superconducting transition temperature (<20 K). Superconductors having high superconducting transition (>100 K). 2. Due to the formation of superconductivity from holes, it

Factors that Affect the Superconducting Property

Physics /

Impurities : When the impurities are added to superconducting material, the properties can be changed abruptly. In particular the magnetic properties can be changed. Size : If the size is reduced below 100μm the superconducting properties such as magnetic permeability is no longer zero and critical magnetic field (Hc) increases than bulk material. Frequency :

Stereospecific Reaction

Stereospecific and Stereoselective Reactions

Health Science /

In stereospecific reactions, one stereoisomer of the product is obtained if one stereoisomer of the reactant is present, while different stereoisomers of product are obtained when different stereoisomer of the reactant are present. Thus for determining whether a reaction is stereospecific or not, one has to analyse the product ratio from the different stereoisomer of

Conformational Isomerism – Pedagogy Zone

Health Science /

Conformational isomerism: Isomers resulting from different arrangements of the atoms in space due to the rotation of groups around C-C bond axis are known as conformational isomers. The study of these confirmations or conformational isomers is known as conformational analysis which involves analysis of the shapes that molecules can adopt by rotation about single bond.

Ferromagnetic Materials 2

Classification of Ferromagnetic Materials

Physics /

Based on permanent magnetic dipoles, materials are further classified into Antiferromagnetic materials Ferrimagnetic materials Antiferromagnetic materials Definition: When the magnitudes of all the antiparallel aligned magnetic dipoles of a material are equal and the resultant magnetisation becomes zero, the material is called antiferromagnetic material. Examples: Manganese oxide (MnO), Chromium oxide (Cr2O3), Ferrous oxide (FeO), etc. This is
