Electric double-layered magnetic particles

Martmez-Pedrero R, Tirado-Miranda M., Schmitt A., and Callejas-Femandez J. 2007. Structure and stability of aggregates formed by electrical double-layered magnetic particles. Colloids Surf. A 306 158-165. 

The second part covers the structural aspects of different colloidal systems. Chapters 3 and 4, by Martin-Molina et al. and Haro-Pdrez et al., deal with electric double layers and effective interactions. Chapters 5 and 6, by Delgado et al. and Martinez-Pedrero et al., explore the structure of extremely bimodal suspensions and fllaments made up of miaosized magnetic particles. Chapters 7 and 8, by Puertas and Fuchs, and Hynninen et al., analyze the role played by the attractive interactions, confinement, and external fields on the structure of colloidal systems. Chapters 9 and 10, by Tromp and Maldonado-Valderrama et al., cover some structural aspects in food emulsions. This second part of the book finishes with Chapter 11, by de Vicente, which analyzes the rheological properties of structured fluids in order to establish a connection between measured material rheological functions and structural properties. 

The motion of electrically charged particles or molecules in a stationary medium under the influence of an electric field is called electrophoresis. In such transport the electric force is applied through a potential difference between electrodes. Selective use of the Lorentz force by applying a magnetic field can also induce such movement. Electrophoresis and electroosmosis are two key modaUties of electrokinetic transport which are very useful in micro- and nanofluidics for a variety of apphcations including biomedical (bio-NEMS, etc.), fuel cell, and micro total analysis systems (/r-TASs). In electroosmosis the bulk fluid moves due to the existence of a charged double layer at the solid-hquid interface. While one-dimensional electrophoresis is more commonly used, two-dimensional electrophoresis may also become a useful tool for the separation of gel proteins based on isoelectric property.
