Rapidity of the change of the Kohlrausch exponent of the alpha-relaxation of glass-forming liquids at TB or Tbeta and consequences

Article Abstract:

A study of the molecular dynamics of the glass transition phenomenon over broad temperature ranges uses a coupling model to address interesting experimental findings reported in a previous experiment. One of these findings is that the temperature dependence of the alpha-relaxation time of many small molecule glass-forming liquids undergoes change at a characteristic temperature. Results of the study are discussed.

Relations between the alpha-relaxation and johari-goldstein beta relaxation of a component in binary miscible mixtures of glass-formers

Article Abstract:

A study is conducted to describe the alpha-relaxation dynamics of the components in miscible mixtures A(sub 1-x) Bx of two different glass formers A and B. The results of n(sub A) obtained from the study show that its change with the composition x and follows the same pattern to address that only alpha-relaxation dynamics of a component in binary mixture is based on coupling model.

The Johari-Goldstein [beta]-relaxation of water

Article Abstract:

The evidence for the existence of Johari-Goldstein secondary relaxation of water identified by the [nu]-process which could be useful to understand the glass transition of bulk water and dynamics of water/protein mixtures is presented.
