Aims at overcoming the lack of understanding about the operant physics and chemistry that are thought to have inhibited the commercial exploitation of liquids that change rheology when placed in an electric field, which have been known for over half a century. The 29 papers cover general considerations, materials, mechanisms, mechanics, and models; and provide historical and technological overviews. Among the specific topics are conduction processes, surface-activated suspensions, fluid inks, the role of particle polarization dynamics in transient stresses, and structure formation. For scientists and engineers in or entering the field. Annotation c. by Book News, Inc., Portland, Or.
