Glass-forming liquids characteristic temperatures

The thermodynamic path to glass formation is marked by other characteristic temperatures besides Ta- These characteristic temperatures are universal in glass-forming liquids and serve to define the breadth and nature of glass... 

The narrow transformation range commonly referred to as the glass transition is the temperature interval where the characteristic molecular relaxation time becomes of the order of 100 s (the laboratory time scale). The viscosities of several glass-forming liquids are shown in Fig. 3 as a... 

E. Comparison of the Characteristic Temperatures of GB and Glass-Forming Liquids... 

A best-fit of the data in Fig. 3 to Eq. (2) yields the characteristic temperature. To = (509 18K) (error estimate is based on a 95% confidence interval through out this chapter) and below we compare the ratio, D= Qy lk To, the fragility parameter in glass-forming liquids, for our GB dynamics to D for appropriate...
