Gellan gum, a microbial polysaccharide, consisting of tetra-saccharide unit, glucose, glucuronic acid, glucose and rhamnose, forms a transparent gel which is heat-resistant in the presence of divalent cations. Since 1989, the collaborative research group was organised in the Research Group of Polymer Gels affiliated to the Society of Polymer Science, Japan, consisting of various laboratories with different disciplines to clarify the mechanism using the common purified sample. This special issue contains 19 papers on the molecular conformation, gel-sol transition, interaction of gellan and...

This volume includes 19 contributions to the 13th International Symposium on Analytical Ultracentrifugation which took place at the university of Osnabruck on March 6th and 7th, 2003. The contributions from leading scientists cover a broad spectrum of topics concerning: Technical Methods, Data Analysis, Innovations; Polymers, Colloids, Supramolecular Systems; Biological and Interaction Systems; Hydrodynamics and Modelling.

Due to the increasing significance of Analytical Ultracentrifugation for both scientific and technical applications, this book will be an essential...

This volume includes 20 contributions of the 12th meeting on Analytical Ultracentrifugation from March 1-2, 2001 in Duisburg, Germany. Various fields of ultracentrifugation are covered concerning research problems in biochemistry, biophysical chemistry and macromolecular chemistry as well as interacting systems. New investigations concerning the sedimentation theory are presented. The phase transition of gels is dealt with, as is the sedimentation-diffusion equilibrium of gels. One section contains the hydrodynamics of biopolymers.

The 9th Symposium on Analytical Ultracentrifugation (AUC) which was held at the Max Delbruck Center for Molecular Medicine in Berlin-Buch, March, 1995, is the basis of this volume. It presents an actual survey of recent developments and results of ultracentrifugation methods in the frame of the following topics: Reversible Association Reactions.- Analysis of Supramolecular Structures Including Modeling.- Size Distribution Analysis and Gel Formation.- Hardware and Software Developments.

The 38th General Meeting of the German Colloid Society was held at the University of Essen, Germany, from September 29th to October 2nd, 1997. The selection of papers presented in this volume covers a broad range of fundamental aspects as well as recent developments. - It focuses the following sections: - Technical applications; - Advanced experimental techniques; - Thin films and interfaces; - Suspensions and microcapsules; - Emulsions, microemulsions and foams; - Macromolecules; - Association colloids; - Colloidal systems in environmental science.

This volume contains the proceedings of the 28th Europhysics Conference on Macromolecular Physics held in Ulm, Germany, in September 1993. The topic covers a broad scope within the field of polymer science. In its early days, interest was focused on the nature of the melt and of the glass transition. The latter phenomen underwent a pronounced renewal with the advent of the mode coupling theory, and polymers constitute only one class of substances within this context. Consequently, this volume considers the glass transition from different points of view. It is the aim of this publication to...

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 Schatzel 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.

The International Symposium on Colloid and Polymer Science was held at Nagoya Institute of Technology, Nagoya, Japan, in October 1996. The program covered both the fundamental aspects as well as technological applications of micelles, microemulsions, monolayers, and biocolloids. Special emphasis was placed on formation and dynamics of self-organized structures, including technical developments, applications, general theory, and results of investigations.

This volume contains the proceedings of the VIIIth annual meeting of the European Colloid and Interface Society (ECIS) which took place in Montpellier, France, in September 1994.
The contributions cover a broad range of fields in modern colloid science, as well as their technical, experimental and theoretical aspects. Specific emphasis is given to:
- Mixed systems: amphiphilic phases incorporating foreign particles
- Concentrated suspensions and emulsions: structure and mechanical properties
- Interactions and long-range order
- Supramolecular structures under...
