An authoritative account of theory, methods and applications of colloid science, extensively updated with new developments and results.

The Colloidal Domain delivers a comprehensive and up-to date treatment of colloid science theory, methods and applications emphasizing the molecular interactions that determine properties on the colloidal length-scale. The book gives an authoritative account of the science describing the colloidal domain.

Concept maps preceding each chapter put subject matter into perspective. Numerous worked examples illustrate key concepts, and more than 250 illustrations help to clarify processes described. Exercises are provided at the end of each chapter.

In this new edition all chapters have been revised with inclusion of novel developments and original results. Special emphasis on

• Chemical potential as a central concept in the description of colloidal systems
• Experimental methods for studying surfaces and interfaces
• The molecular aspect of electrostatic interactions
• A comprehensive overview of scattering methods
• A classification of interparticle forces based on molecular mechanisms
• Function of bilayer systems in a biological context
• Association behaviour of biopolymers
• Amyloid formation as a colloidal instability
• Synthesis of colloidal particles
• Liquid-liquid phase separation as a general phenomenon
• Emphasizing role of monolayer spontaneous curvature in emulsions and foams

The Colloidal Domain is an indispensable resource for students, scientists and professionals in molecular bioscience, chemistry and chemical engineering. Applications span a wide range from cellular phenomena, formulation problems, pharmaceutical science, food technology, coating processes, cosmetics development, ceramics and paper products.

Håkan Wennerström is an Emeritus Professor of Physical Chemistry at the Department of Chemistry, Lund University, Sweden. He is the author of more than 250 publications mainly in colloid science in the areas of surfactant and lipid phase behavior, surface forces, electrostatic interactions, and nuclear magnetic resonance spectroscopy. He was a member of the Nobel Committee for Chemistry for 14 years and its Chairman for three years.
