Extension of the Angell fragility concept
Article Abstract:
A study on the concept of fragility in relation to the relaxation behavior of supercooled liquids introduces a classification scheme derived from that proposed by scientist C. Austen Angell but which distinguishes between the high-temperature Arrhenius behavior and low-temperature super-Arrhenius behavior. The high T-behavior was classified as weak or strong and the low-T behavior as fragile or non-fragile. The experiment found examples with all four combinations of these two categories.

Nonlinear kinetic and thermodynamic properties of monomeric organic glasses
Article Abstract:
A study on the temperature dependence of relaxation and retardation times of supercooled liquids compares identical preparations of the three isomers of indane and of O-terphenyl and tri-alpha-naphthyl benzene. The experimental values of thermodynamic Kauzmann temperature, published dielectric relaxation and viscosity Fulcher temperatures and non-linear enthalpic Adam-Gibbs temperatures of these preparations were scrutinized. Results are discussed.
