Book Description
The dielectric properties especially of glassy materials are nowadays explored at widely varying temperatures and pressures without any gap in the spectral range from μHz up to the Infrared, thus covering typically 20 decades or more. This extraordinary span enables to trace the scaling and the mutual interactions of relaxation processes in detail, e.g. the dynamic glass transition and secondary relaxations, but as well far infrared vibrations, like the Boson peak. Additionally the evolution of intra-molecular interactions in the course of the dynamic glass transition is also well explored by (Fourier Transform) Infrared Spectroscopy. This volume within 'Advances in Dielectrics' summarizes this knowledge and discusses it with respect to the existing and often competing theoretical concepts.

Book Description
Stochastic processes with a special class of non-stationary transition rates (NSTR) that can be related to stationary rates (STR) by time scale transformations are considered. Calculations are carried out on the time scale on which the process has STR and then related to the time scale of measurements by a time scale transformation. Application is made to Gaussian Markoff processes with a single transition rate. The resulting equilibrium autocorrelation function departs from weak stationarity. A response function is related to the Autocorrelation function and specialized to relaxation processes to yield a model consistent with Ngai's recent model of relaxation. The model is therefore widely applicable in the description of measured relaxation behavior and leads naturally to Ngai's renormalization relation for excitation energies. On the basis of the success of the model, consideration is given to the possibility that the process should be viewed as one with STR and an intrinsic time scale so that the process only appears to have NSTR on the time scale of measurements.

Book Description
The field of non-crystalline materials has seen the emergence of many challeng ing problems during its long history. In recent years, the interest in polymeric and biological disordered matter has stimulated new activities which in turn have enlarged the organic and inorganic glass community. The current research fields and recent progress have extended our knowledge of the rich phenomenol ogy of glassy systems, where the role of disorder is fundamental for the underlying microscopic dynamics. In addition, despite the lack of a unified theory, many interesting theoretical models have recently evolved. The present volume offers the reader a collection of topics representing the current state in the understanding of disorder effects as well as a survey of the basic problems and phenomena involved. The task of compiling a book devoted to disordered systems has benefited much from a seminar organized by the W.-E. Heraeus Foundation in Bad Honnef in April 1992, where we had the opportunity to discuss the project with most of the authors. Here we wish to thank the Heraeus Foundation for their support, and the authors and Springer-Verlag, especially Dr. Marion Hertel, for the pleasant cooperation.

Book Description
Volume IV (2005) covers preparation, characterization of colloids, stability and interaction between pairs of particles, and in concentrated systems, their rheology and dynamics. This volume contains two chapters written, or co-authored by J. Lyklema and edited contributions by A.P.Philipse, H.P. van Leeuwen, M. Minor, A. Vrij, R.Tuinier and T. van Vliet. The volume is logically followed by Vol V, but is equally valuable as a stand alone reference.* Combined with part V, this volume completes the prestigious series Fundamentals of Interface and Colloid Science* Together with volume V this book provides a general physical chemical background to colloid science* Covers all aspects of particle colloids

Book Description
It is difficult to imagine how our highly evolved technological society would function, or how life would even exist on our planet, if polymers did not exist. The intensive study of polymeric systems, which has been under way for several decades, has recently yielded new insights into the properties of assemblies of these complex molecules and the physical principles that govern their behavior. These developments have included new concepts to describe aspects of the many body behavior in these systems, microscopic analyses that bring our understanding of these systems much closer to our understanding of simple liquids and solids, and the discovery of novel chemistry that these molecules can catalyze. This special topic volume of Advances in Chemical Physics surveys a number of these recent accomplishments. Supplemented with more than 250 illustrations, it provides a significant, up-to-date selection of papers by inter-nationally recognized researchers. Topics include: * Theory of Polyelectrolyte Solutions * Star Polymers: Experiment, Theory, and Simulation * Tethered Polymer Layers * Living Polymers * Transport and Kinetics in Electroactive Polymers Self-contained, authoritative, and timely, Polymeric Systems makes the cutting edge of polymer research available to scientists in every branch of chemical physics.

Book Description
This volume contains the Proceedings of the International Workshop on “Non-Equilibrium Phenomena in Supercooled Fluids, Glasses and Amorphous Materials”, held in Pisa in the early fall of 1995 as a joint initiative of the University of Pisa and of the Scuola Normale Superiore. The goal was to bring together liquid state physicists, chemists and engineers, to review current developments and comparatively discuss experimental facts and theoretical predictions in this vast scientific area. The core of the Workshop was a set of general lectures followed by more specific presentations on current issues in the main areas of the field. This structure has been maintained in this volume, in which a set of five overviews is followed by topically grouped contributions in the five areas of ionic glasses and glassy materials, the glass transition, viscous flow and microscopic relaxation, complex fluids, and polymers. The volume also preserves a record of the many short contributions given to the Workshop through posters, which are grouped in it under the subjects of inorganic glasses, organic glasses and complex fluids, polymers, and theoretical aspects.
