This comprehensive reference describes recent developments in the science and engineering of finely dispersed particles and related systems. Written by a team of experts, this book takes an interdisciplinary approach to the elucidation of the heat, mass, and momentum transfer phenomena as well as electron transfer phenomena. It explores hydrodynamic, electrodynamic, and thermodynamic instabilities that occur at interfaces and discusses the properties responsible for the existence of droplets, particles, and droplet-particle-film structures. Addressing numerous applications, the text covers homo-aggregate and hetero-aggregate finely dispersed systems on the mili-, micro-, nano-, and atto-scales.
