Centrifugation - Wikipedia

Centrifugation - Wikipedia

Centrifugation is a mechanical process which involves the use of the centrifugal force to separate particles from a solution according to their size, shape, density, medium viscosity and rotor speed. The denser components of the mixture migrate away from the axis of the centrifuge, while the less dense components of the mixture migrate towards the axis.

Extended X-ray absorption fine structure (EXAFS) measurements show that there is a 0.05 contraction in the Ni–Ni distance, d Ni−Ni, in α-Ni(OH) 2 relative to β-Ni(OH) 2 [].Therefore, the unit cell parameters for the idealized stoichiometry (3 Ni : 2 H 2 O) shown in figure 4 are a=b=5.335 and c=8.0 . Note that the a-parameter depends on the way in which the unit cell …
