Electro-osmotic consolidation is an attractive soil improvement technique for soft clay. A review of research and practical applications of electro-osmosis was performed. The achievements and major bottleneck of the current technique were briefly discussed, and the potential areas for scientific research and engineering application were proposed. A laboratory testing facility was developed for ...

Colloidal particles in electrolytes move in response to electric fields !electrophoresis" and salt concentration gradients !diffusiophoresis", and related flows also occur at fixed surfaces !electro-osmosis and diffusio-osmosis, respectively". In isolation, these electrokinetic phenomena are well understood, e.g., electrophoresis without far-field concentration gradients and diffusiophoresis wi...

We discuss the electrostatic contribution to the elastic moduli of a cell or artificial membrane placed in an electrolyte and driven by a DC electric field. The field drives ion currents across the membrane, through specific channels, pumps or natural pores. In steady state, charges accumulate in the Debye layers close to the membrane, modifying the membrane elastic moduli. We first study a mod...

This study analyses the electrokinetic (EK) contribution to removal from a clay soil of mixture 10 different contaminants emerging concern (CECs; 17?-estradiol, E2; sulfamethoxazole, SMX; bisphenol A, BPA; ibuprofen, IBU; 17?-ethinylestradiol, EE2; oxybenzone, OXY; diclofenac, DCF; triclosan, TCS; caffeine, CAF; carbamazepine, CBZ). After 4 days, CECs natural attenuation was between 0% (CBZ) an...

Ion transport in polyelectrolyte membranes (charged hydrogels) is of significant technological (and biological) importance, but little known how micro-structural inhomogeneity affects ionic conductivity. Whereas a uniform electric field drives uni-directional electro-migrative and electro-osmotic ion fluxes perfectly microstructures, this study considers the influence spherical inclusions/cavit...
