Discovery of a potentially homogeneous-nucleation-based crystallization around the glass transition temperature in salol
TLDR
In this paper, two crystallization processes were observed separately in temperature; one in the range 218-225 K just above a glass transition region and the other above 227 K. It was concluded that the process proceeding around 220 K was probably the homogeneous-nucleation-based crystallization as found out in o -terphenyl, and that the decrease in the interfacial energy between crystal embryo and liquid must have played an important role for the crystallization to be observed macroscopically.About:

Dynamic and thermodynamic properties of glass-forming substances
TL;DR: In this paper, the important general dynamic and thermodynamic properties of structural glass-forming substances and classify them into 12 different categories, including those relating to the high frequency fast relaxation, the Johari-Goldstein β-relaxation, and the slow structural α-Relaxation.

Fragility and thermodynamics in nonpolymeric glass-forming liquids.
TL;DR: For nonpolymeric supercooled liquids, the empirical correlation m = 56Tg DeltaCp(Tg)/DeltaHm provides a reliable means of correlating dynamic and thermodynamic variables and deduces that the fragility cannot exceed m = 170, unless the Tg/Tm = 2/3 rule breaks down.

Local mobility in amorphous pharmaceuticals—characterization and implications on stability
TL;DR: The coupling model, which correlated the local motions with global mobility, has been discussed in order to emphasize the potential impact of local mobility on amorphous phase stability and the Johari-Goldstein relaxations are highlighted.

TL;DR: The crystallization and nucleation kinetics of poly(e-caprolactones) with molar masses between 1.4 and 6.1 kDa and negligible number of heterogeneous nuclei has been investigated by differential fast scanning calorimetry (DFSC) applying scanning rates up to 100 000 K/s.

Nonexponential relaxations in strong and fragile glass formers
TL;DR: In this article, a broad correlation of non-debye behavior with non-Arrhenius relaxations was found for different types of glass formers, distinguished by their respective molecular complexity.

Crystal Nucleation in Liquids and Glasses
TL;DR: In this paper, the authors focus on measurements and theories pertaining to homogeneous nucleation under cooled liquids and glasses that transform to phases of the same composition, and incorporate time-dependent nucleation and the interface kinetics into the field-theoretic approaches to give theories that are as widely applicable and, hence, testable as the classical theory.

On the nature of crystal growth from the melt
TL;DR: The theory of interface motion as applied to crystal growth by Cahn and his coworkers is examined in detail in this article, and it is concluded from this analysis that the theory of Jackson on interface roughness qualitatively predicts crystal growth morphology.
