Diffusion and Electric Conductance in a Polymer Solution

Diffusion of bovine serum albumin in a neutral polymer solution.

The diffusion coefficient D of bovine serum albumin through various solutions (pH 7.0, 0.5M NaCl) of polyethylene oxide ( M , 1 x lo5, 3 x lo5) was studied with quasielastic light scattering. In solutions of the 1 x lo5 polymer solution a t polymer concentrations above 0.5 g/L, D is considerably greater than would have been expected from the viscosity of water:polymer mixtures, the deviations b...

analysis the diffusion process for polymer solution using FTIR-ART technique: special considerations

Diffusion of a sphere in a dilute solution of polymer coils.

We calculate the short time and the long time diffusion coefficients of a spherical tracer particle in a polymer solution in the low density limit by solving the Smoluchowski equation for a two-particle system and applying a generalized Einstein relation (fluctuation dissipation theorem). The tracer particle as well as the polymer coils are idealized as hard spheres with a no-slip boundary cond...

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
