* The Stokes-Einstein equation is the equation first derived by Einstein in his Ph*.D thesis for the diffusion coefficient of a Stokes particle undergoing Brownian Motion in a quiescent fluid at uniform temperature. The result was formerly published in Einstein's (1905) classic paper on the theory of Brownian motion (it was also simultaneously. force given by Stokes law. Therefore, using equation (61) in equation (63), we get ̅ = − / = 6 = 1 6 (64) At this stage, recall the famous Einstein's relation between the absolute mobility and diffusion coefficient, i.e., = ̅ (65 Stokes-Einstein equation In the limit of low Reynolds number , the mobility μ is the inverse of the drag coefficient ζ {\displaystyle \zeta } . A damping constant γ = ζ / m {\displaystyle \gamma =\zeta /m} is frequently used for the inverse momentum relaxation time (time needed for the inertia momentum to become negligible compared to the random momenta) of the diffusive object In SI units, F d is given in newtons (= kg m s −2), μ in Pa·s (= kg m −1 s −1), R in meters, and v in m/s. Stokes' law makes the following assumptions for the behavior of a particle in a fluid: Laminar flow; Spherical particles; Homogeneous (uniform in composition) material; Smooth surfaces; Particles do not interfere with each other Thus the reference isomorph marks roughly the upper limit of the part of the phase diagram in which the isomorphic version of the Stokes-Einstein relation D ̃ η ̃ = Const. holds. The bottom line of the above is that the role of the hydrodynamic diameter is taken by the length defined by density, l 0 = ρ −1/3 , a measure of the average interparticle spacing

The diffusion coefficient D of a sherical particle istproportional to its mobility: Substituting the frictional coefficient of a perfect sphere from Stokes' law by liquid's viscosity and sphere's radius we have Stokes-Einstein equation ** Einstein's equation relates the atomic flux J (i**.e., the number of atoms crossing unit area per unit time) to the electron wind force: (128)J = DZ * eρj Ω kT. where D = D0 exp (- Q / kT) is the diffusion coefficient, Q is the activation energy, and Ω is the volume per atom in the metal The self diffusion coefficient for isolated Brownian spheres is given by the Stokes-Einstein equation, where is the viscosity of the suspending fluid and is the sphere's radius. For the spheres in the example data, m /s at the experimental temperature C, in good agreement with the measured value Abstract. By adopting a simple notion of the volume of a molecule it has been possible to produce an empirical correction factor for the Stokes equation to enable one to apply it to molecules down to two angstroms in radius.

The Stokes-Einstein equation relates the diffusion constant D of a macroscopic particle of radius r undergoing a Brownian motion to the viscosity eta of the fluid in which it is immersed. It is a beautiful and simple example of a fluctuation-dissipation relation. But suppose now we think about one of the individual atoms or molecules in the fluid After digitally rotating the Stokes vector →S(t) = S1(t)ˆs1 + S2(t)ˆs2 + S3(t)ˆs3 (where the unit vectors ˆs1, ˆs2, and ˆs3 are a right-handed basis of Stokes space), so that its time-averaged value is aligned to ˆs1, the Stokes vector can be converted back to Jones space with a simple operation X = S2(t) ± iS3(t)

** Stokes-Einstein Equation The progress of science has owed much to the use of models: mental pictures helpful in explain-ing phenomena**.
