Description
Description
Phoretic Motions of Liquid Droplets: A Theoretical Analysis provides a detailed description of the fundamentals of the electrostatics and electrokinetics of various kinds of droplets: dielectric droplets, conducting droplets such as liquid metal droplets, polymeric liquid droplets and the implications they have for their broad practical applications. It is crucial to fully understand the underlying electrokinetic mechanisms before any meaningful practical applications of liquid droplets can be launched successfully.
This is the first book to directly address phoretic motion of droplets; previously there has only been brief mention in texts mostly about solid particles, on which there is much more literature. Droplets of different kinds have different applications in practice. For instance, conducting droplets like liquid metal droplets have an inherent advantage in drug delivery over liposomes of dielectric droplets in terms of chemiphoresis, although both are widely used in drug delivery and micro/nanofluidic operations, among other practical applications. The book provides insights and guidelines for design engineers in drug delivery even in the fabrication stage of the droplets carrying therapeutic chemicals. Moreover, it is helpful in analyzing data for experimental researchers as well. For instance, a droplet filled with dielectric materials may not behave electrokinetically like a dielectric droplet under certain circumstances in practice, as might be expected by experimentalists.
Phoretic Motions of Liquid Droplets is written for researchers, industry engineers, and graduate and postdoc students in the field of colloidal and interface science and technology who are working on colloidal physics aspects and focused on electrokinetics, primarily from a chemical engineering, biomedical and biochemical engineering background.
Key features
Key features
- Provides comprehensive electrokinetic insights into the behaviors of various kind of droplets conducting phoretic motions and explains clearly why they behave like that

Eric Lee
Eric Lee is a Professor in the Department of Chemical Engineering, National Taiwan University, Taipei, Taiwan. He obtained a PhD in Chemical Engineering in 1986 from the University of Washington, USA. His research areas include polymeric fluid mechanics and electrokinetic motions of colloidal particles. He investigates the fluid motion of liquid phase systems containing polymers, such as polymer solutions, polymer melts, and other non-Newtonian fluids. Further he investigates the general electrokinetic behavior of colloidal particles of sub-micron or nano-scale dimensions in either dilute or concentrated suspensions, focusing on the electrophoretic motion above all. The impact of air-water interface as well as particle migrations in gel or porous media has been of particular interest in recent years. In 2005 he received the National Taiwan University Fu Sinian Award. Eric Lee has published more than 70 articles in international scientific journals.
