Electrical Phenomena at Interfaces

Hiroyuki Ohshima

Fundamentals: electrical double layer; electrokinetics; interaction of electrical double layers; electrocapillarity and double layer structure; DLVO theory of colloid stability; concentrated dispersion; nonaqueous systems. Measurements: electrophoresis; electroosmosis and streaming potential; sedimentation potential and flotation potential; surface potential measurements of monolayer; capillary electrophoresis - revisit to capillary; dynamic electrophoresis; surface conductivity; evaluation of surface characteristics of powder; stability measurements of disperse systems. Applications: detergency; flotation; paper; paints and pigments; cosmetics; colloidal aspect of rusting on weathering steel; electric double layer on latex surface and protein adsorption; calculation of viscosities of cement pastes based on a new rheological theory; coal water mixture; ceramics and composites; phospholipid membranes; electrostatic and electrokinetic properties of micelles; emulsion and gel; biological cells and model systems; electroosmosis on biological surfaces; proteins and sugars; application in agriculture.
