Session 3: Glass, entropy, and the glass transition



Divergence of timescales, the glass transition, the role of configurational entropy, and the extrapolations to absolute zero remain issues of fundamental curiosity, and their understanding also begins to have impact in concrete applications of glass. Interestingly, very similar approaches are taken in fields as different as melt-derived glasses, glass transitions in paramagnetic and superparamagnetic materials, or collapsing zeolites. It is anticipated that the bridging consideration of experimental and computer-generated glass transitions may provide a new perspective at some of the application-related problems of glass science, subject to the present session.


  • Divergence from super-Arrhenian viscosity–temperature dependence
  • Slow relaxation and transport reactions in glasses
  • Arrhenian reaction kinetics
  • Relations between diffusion effects, ionic conductivity, and long-term relaxation
  • Structural origin of melt viscosity
  • Superparamagnetic blocking
  • Zeolite collapse
  • Low-temperature studies
