Book Description
This book covers the physical side of colloidal science from the individual forces acting between particles smaller than a micrometer that are suspended in a liquid, through the resulting equilibrium and dynamic properties. A variety of internal forces both attractive and repulsive act in conjunction with Brownian motion and the balance between them all decides the phase behaviour. On top of this various external fields, such as gravity or electromagnetic fields, diffusion and non-Newtonian rheology produce complex effects, each of which is of important scientific and technological interest. The authors aim to impart a sound, quantitative understanding based on fundamental theory and experiments with well-characterised model systems. This broad grasp of the fundamentals lends insight and helps to develop the intuitive sense needed to isolate essential features of the technological problems and design critical experiments. The main prerequisites for understanding the book are basic fluid mechanics, statistical mechanics and electromagnetism, though self contained reviews of each subject are provided at appropriate points. Some facility with differential equations is also necessary. Exercises are included at the end of each chapter, making the work suitable as a textbook for graduate courses in chemical engineering or applied mathematics. It will also be useful as a reference for individuals in academia or industry undertaking research in colloid science.

Book Description
Many fundamental issues in classical condensed matter physics can be addressed experimentally using systems of individually visible mesoscopic particles playing the role of “proxy atoms”. The interaction between such “atoms” is determined by the properties of the surrounding medium and/or by external tuning. The best-known examples of such experimental model systems are two different domains of soft matter — complex plasmas and colloidal dispersions.The major goal of this book — written by scientists representing both complex plasmas and colloidal dispersions — is to bring the two fields together. In the first part of the book the basic properties of the two systems are summarized, demonstrating huge conceptual and methodological overlap of the fields and emphasizing numerous cross-connections between them and their essential complementarity. This “introductory part” should serve to help each community in understanding the other field better. Simultaneously, this provides the necessary basis for the second part focused on particle-resolved studies of diverse generic phenomena in liquids and solids — all performed with complex plasmas and/or colloidal dispersions. The book is concluded with the discussion of critical open issues and fascinating perspectives of such interdisciplinary research.

Book Description
Phase behavior and dynamical properties of repulsive and attractive colloidal systems were studied by optical microscopy. The optical video microscopy technique is used to study directly particle motions by measuring the positions of individual particles. The technique also offers the possibility to check up on different suggested mechanisms of motion by directly following the particle trajectories in real space using colloidal particles as mesoscopic model atoms. The dynamics of concentrated colloidal soft-sphere suspensions at high polydispersity have not yet been studied by video microscopy. Here, the interest results from the possibility to visualize physical processes as glass transitions, cage effects or cluster formations. A model colloidal system was chosen in order to mimic previous works of nearly hard spheres reported with light scattering. The colloidal model system was chosen to consist of a binary mixture of Teflon core-polystyrene shell and polystyrene microgel particles in a good organic solvent to which a certain amount of linear polystyrene was added. The colloidal model system is particularly considered more complex than the system studied in previous works due to the core-shell nature of the monitored particles, the softness and the polydispersity. It is demonstrated that concentrated glassy solutions melt upon addition of small amounts of linear polystyrene, as manifested by speeding up the diffusion of the particles. As the amount of linear polystyrene increases, the particles start to aggregate to stable clusters. Dynamical arrest is generated via cluster formation and a reentrant glass transition is found. This reentry region is much larger than predicted by theory and reported for another colloidal system with depletion attractions. These discrepancies have been related, especially to the core-shell nature of particles, softness and polydispersity.

Book Description
This volume is based on lectures given at the NATO-Advanced Study Institute on Structure and Dynamics of Polymer and Colloid Systems held in Les Houches, France from September 14-24, 1999. The meeting arose from a perceived need to bring together scientists studying the polymer and colloid fields. Although these fields are intertwined and share many techniques (e. g. , light, neutron and x-ray scattering), it is remarkable how little the approaches and concepts used by the one field penetrate the other. For instance, the theory of spherical colloids is very highly developed and many of the concepts developed for these systems can be extended to those with non-spherical morphology, such as solutions of rigid rod polymers. In addition, mixtures of polymers and colloids, both in the bulk and at interfaces, are the basis for many industrial products. Methods are now rapidly being developed for understanding the structure and dynamics in polymer/colloid mixtures at the molecular level, but the point of view of the colloid scientist is often rather different from that of the polymer scientist. The NATO-ASI brought together polymer and colloid scientists, including many young researchers, who presented and discussed recent developments in these fields and the possibilities for cross-fertilization This volume contains articles on a wide variety of topics at the research forefront of the polymer and colloid fields by some of the world's foremost experts at a level accessible to graduate students, post-docs and researchers.

Book Description
This volume contains the proceedings of the "International Workshop on Optical Methods and the Physics of Colloidal Dispersions", held in memory of Prof. Dr. Klaus Schätzel at the end of September, 1996, in Mainz, Germany. The meeting focused on two special aspects of colloidal science, namely novel optical methods and the physics of colloidal dispersions. In particular, the contributed papers show that the increase in the quality and number of suitable model systems has significantly enhanced our knowledge of colloidal properties, structures and dynamics.
