Cryogenic grinding of indomethacin polymorphs and solvates: Assessment of amorphous phase formation and amorphous phase physical stability
Kieran J. Crowley,George Zografi +1 more
TL;DR: It is argued that physical factors, namely residual crystal phase and specific surface area, determine the isothermal and nonisothermal crystallization behavior of ground amorphous samples as opposed to intrinsic differences in the structure of theAmorphous phase.

Calorimetric evidence for the microquasicrystalline structure of amorphous Al/transition metal alloys
Lincoln C. Chen,Frans Spaepen +1 more
TL;DR: The idea that a material exhibiting broad diffraction halos does not have a characteristic amorphous structure but is just an assembly of randomly orientated microcrystals is a remarkably resilient one as mentioned in this paper.

Overview No. 98 I—Geometric models of crystal growth
TL;DR: In this paper, the authors provide an introduction to nine mathematical methods for solving such problems, give the limits of applicability of the methods, and discuss the relations among them theoretically and their uses in computation.

A New Approach to Modeling the Nucleation and Growth Kinetics of Tricalcium Silicate Hydration
TL;DR: In this paper, the hydration kinetics of tricalcium silicate (C3S), the main constituent of portland cement, were analyzed with a mathematical "boundary nucleation" model in which nucleation occurred only on internal boundaries corresponding to the C3S particle surfaces.

Internal structures of zircons from Archaean granites from the Darling Range batholith: implications for zircon stability and the interpretation of zircon U-Pb ages
TL;DR: The trace element bands formed by migration of trace elements from the outer primary zones to new concentration sites on an inner set of primary zones are found in zircons from a number of granites as discussed by the authors.
