Preface The w o r l d o f real colloidal dispersions i n soils, emulsions, reproduction, and printing technologies, pharmaceuticals formulation, surface coatings, food and household products, and the like invariably involves concentrated or dense suspensions where the dispersed phase can be as large as 5 0 % or more by volume. The classical experimental tools o f light scattering or microelectrophoresis, for example, are o f limited value i n such systems and the classical D e r j a g u i n - L i n d a u - V e r w e y Overbeck ( D L V O ) theory o f the stability o f such systems ignores many body interactions. M a r k e d advances i n experiment, theory, and technology have allowed the field o f concentrated dispersions to progress significantly during recent years. A symposium "Concentrated Colloidal Dispersions: Theory, Experiment, and Applications" was conducted at the A m e r i c a n Chemical Society meeting i n Orlando, Florida i n 2002 to review the current state o f knowledge o f this centrally important field i n colloidal science and to explore new research directions. Theorists, experimentalists, and technologists were brought together to review progress i n the areas o f dense dispersion systems; modeling and many body theoretical effects; basic and applied rheology; electrokineticeffects; and sensing and measurement o f size, charge, and forces; structures i n dense particulate systems; synthesis o f special emulsion droplets and nanopartieles; confirmation o f polymers; aggregation o f particles; and dynamics o f free and adsorbed polymer molecules i n concentrated suspensions. Selected papers were reviews b y experts i n the field and were refined as required before the presentations. W e feel that this compilation presents a comprehensive examination o f the progress made on concentrated dispersions along with problems and opportunities apparent through the chapters.
