Crystallization and Crystal Data of Monellin [PDF]
Proceedings of the National Academy of Sciences, 1975 Crystals of monellin, a sweet protein from Dioscoreophyllum cumminsii , were grown by vapor diffusion of 20% ethanol into buffered protein solution. The crystals are orthorhombic, belonging to space group P2 1 2 1 2, with a = 54.4 Å,

Unveiling the self-association and desolvation in crystal nucleation
IUCrJ, 2021 As the first step in the crystallization process, nucleation has been studied by many researchers. In this work, phenacetin (PHEN) was selected as a model compound to investigate the relationship between the solvent and nucleation kinetics.

Conversion of stable crystals to metastable crystals in a solution by periodic change of temperature [PDF]
, 2023 Using a Becker-D\"oring type model including cluster incorporation, we study the possibility of conversion of stable crystals to metastable crystals in a solution by a periodic change of temperature. At low temperature, both stable and metastable crystals grow by coalescence with abundant clusters.

Explosive crystallization mechanism of ultradisperse amorphous films [PDF]
, 1999 The explosive crystallization of germanium ultradisperse amorphous films is studied experimentally. We show that crystallization may be initiated by local heating at the small film thickness but it realizes spontaneously at the large ones.
