time by Robert Millikan. Avogadro’s number can be measured if the charge on a mole of electrons is divided by the charge on a single electron. Another method is to use density of an ultrapure sample of a material on the macroscopic scale. X-ray diffraction techniques are used to find the density on the atomic scale and the number of atoms in the crystal is determined. Also‚ the distance between the equivalent points that define the unit cell can be used to measure the Avogadro’s

Sir Chandrasekhara Venkata Raman‚ FRS (Tamil: சந்திரசேகர வெங்கடராமன்) (7 November 1888 – 21 November 1970) was an Indian physicist whose work was influential in the growth of science in the world. He was the recipient of the Nobel Prize for Physics in 1930 for the discovery that when light traverses a transparent material‚ some of the light that is deflected changes in wavelength. This phenomenon is now called Raman scattering and is the result of the Raman effect. Contents * 1 Early years

Paragraph 1 Perovskite‚ with a general formula of ABO3‚ has a structure comparable to that of ReO3. What differentiates them is the fact that ReO3 lacks the cation A at its unit cell centres. An octahedron made up of six oxygen atoms encompasses each rhenium atom‚ and it forms the 3-dimensional structure by connecting its corners with other octahedral. At low temperatures and a pressure of about 3kbar‚ the Fermi-surface cross sections undergo nonlinear patterns. ReO3 thus undergoes phase transitions
