Opis

This volume contains the proceedings of the Europhysics Conference on Gels, held in Balatonszeplak, Hungary, in September 1995.
Topics of the contributions cover fundamentals and applications of gels formed from inorganic and organic polymers, colloidal particles and surfactant systems, new powerful methods such as scattering techniques, rheology, atomic microscopy, swelling pressure and mechanical measurements, gels with sensitivity to changes in chemical and physical environment, novel technical and biomedical applications, computer simulation and new theoretical approaches.
