Glass Transition, Crystallization of Glass-Forming Melts, and Entropy
A critical analysis of possible (including some newly proposed) definitions of the vitreous state and the glass transition is performed and an overview of kinetic criteria of vitrification is presented. On the basis of these results, recent controversial discussions on the possible values of the residual entropy of glasses are reviewed. Our conclusion is that the treatment of vitrification as a...
متن کاملSelf-Organized Criticality Below The Glass Transition
– We obtain evidence that the dynamics of glassy systems below the glass transition is characterized by self-organized criticality. Using molecular-dynamics simulations of a model glass-former we identify clusters of cooperatively jumping particles. We find string-like clusters whose size is power-law-distributed not only close to Tc but for all temperatures below Tc, indicating self-organized ...

متن کاملPhysical stability of drugs after storage above and below the glass transition temperature: Relationship to glass-forming ability
Amorphous materials are inherently unstable and tend to crystallize upon storage. In this study, we investigated the extent to which the physical stability and inherent crystallization tendency of drugs are related to their glass-forming ability (GFA), the glass transition temperature (Tg) and thermodynamic factors. Differential scanning calorimetry was used to produce the amorphous state of 52...
متن کاملEnhanced cooperativity below the caging temperature of glass-forming liquids
– The utility of a cooperative length scale for describing the dynamics of small molecule glass-formers is shown. Molecular Dynamics and Monte Carlo simulations reveal a distribution of cooperatively moving fractal events below the temperature TA at which dynamics become caged. Guided by these results, four straightforward methods emerge to recognize TA in experimental data and quantify the len...
