Determination of the Avrami exponent for solid state transformations from non-isothermal differential scanning calorimetry
TL;DR: In this paper, a computer model was developed to generate non-isothermal differential scanning calorimeter curves, which are strongly dependent on the values of the Avrami exponent and are nearly independent of all other variables.

Formation of Martensite
TL;DR: Martensite is a diffusionless, shear transformation that is highly crystallographic in character because it is generated by a specific deformation of the austenite as discussed by the authors, which is known as the martensite habit.

The formation of zeolites from solution – Analysis by mass spectrometry
TL;DR: In this paper, the authors present the application of mass spectrometry in studying zeolite formation, including instrumentation, structural analysis, dynamics of silicate species, heteroelement incorporation, and the study of nucleating solutions.

Effects of Moisture and Residual Solvent on the Phase Stability of Orthorhombic Paracetamol
Kyriakos Kachrimanis,Katharina Fucke,Michael F. Noisternig,Bernd Siebenhaar,Ulrich J. Griesser +4 more
TL;DR: Moisture triggers the growth of existing form I nuclei but it exerts a weaker effect on nucleation, and the presence of residual ethanol greatly accelerates the transformation.
