摘要: The motion of dilute and concentrated dispersions colloids by external electric or magnetic fields is discussed. Electrokinetics studied for in confinement, where the confining walls can be flat rough. As an example a rough wall superhydrophobic surfaces are chosen. It shown that reduced friction at water-air interface insufficient to enhance electro-osmosis. Magnetic particles pulled through crystalline matrix formed nonmagnetic investigate local melting recrystallization matrix. average strain field calculated reorganization processes compared those induced shear fields. Using single domain, magnetically blocked different shape surface characteristics, interplay between particles, their environment investigated.
