Electrokinetics
1. The question of the critical pore diameter for streaming potential is discussed. 2. The surface charge is calculated for cellulose in contact with solutions of K(3)PO(4), K(2)CO(3), K(2)SO(4), KCl, and ThCl(4). 3. The surface charge of cellulose in contact with a solution of 2 x 10(-4)N NaCl is calculated as a function of temperature and is found to show a sharp break at 39 degrees . This is...
متن کاملContaminant Extractability by Electrokinetics
Electrokinetic extraction is an emerging technology that has shown considerable potential for efficient and effective removal of both inorganic and organic contaminants from fine-grained soils of low hydraulic conductivity and large specific area when conditions are favorable. The cleanup technology is basically the application of a direct-current electric field across contaminated soils throug...
متن کاملNonlinear electrokinetics and "superfast" electrophoresis.
Nonlinear and nonequilibrium electrophoresis of spherical particles of radius a is shown to be possible when the solid surface allows field or current penetration. At low particle Peclet numbers, transient capacitative charging occurs until the surface polarization completely screens the external field. For a DC applied field [see text], the resulting electrokinetic velocity reaches Dukhin's ma...
متن کاملNonlinear electrokinetics at large voltages
The classical theory of electrokinetic phenomena assumes a dilute solution of point-like ions in chemical equilibrium with a surface whose doublelayer voltage is of order the thermal voltage, kBT/e = 25 mV. In nonlinear ‘induced-charge’ electrokinetic phenomena, such as ac electro-osmosis, several volts ≈100kBT/e are applied to the double layer, and the theory breaks down and cannot explain man...
متن کاملMicrotubule alignment and manipulation using AC electrokinetics.
The kinesin-microtubule system plays an important role in intracellular transport and is a model system for integrating biomotor-driven transport into microengineered devices. AC electrokinetics provides a novel tool for manipulating and organizing microtubules in solution, enabling new experimental geometries for investigating and controlling the interactions of microtubules and microtubule mo...
