Cell model of the direct current electrokinetics in salt-free concentrated suspensions: The role of boundary conditions

Article Abstract:

A study uses a cell model to derive the electrokinetic equations for salt-free suspensions with special emphasis in electrical conductivity and electrophoretic mobility, and revises and compares it with previous salt-free electrophoresis models. Results demonstrate that the electrophoretic mobility and also the conductivity are practically unchanged if a complete boundary condition is used instead of the approximated one.

Morphologies of star-block copolymers in dilute solutions

Article Abstract:

The morphologies of star-block copolymer [(AB).sub.n] and [(BA).sub.n] in a selective solvent for A-block are investigated by using dissipative particle dynamics. As the length of B-blocks or the repulsive interaction between B-blocks and solvents is increased, the tendency of B-blocks to associate within the star increases and thus the average number of aggregative domains declines.

Temperature-insensitive electrokinetic behavior in capillary zone electrophoresis

Article Abstract:

A simple analytic theory was derived to show that when the electric current was steady, the electro-osmotic flow remained pluglike regardless of the temperature profile inside the capillary due to Joule heating and nonuniform surrounding convection. The temperature-insensitive behavior was caused by the cancellation of the temperature effects.
