Molecular Mechanism of Polymorphic Transitions
TLDR
In this article, serious problems arise with the usual classification and proposed mechanisms for polymorphic transitions in crystals, and it is shown that serious problems arises with the traditional classification and mechanism.Abstract:
It is shown that serious problems arise with the usual classification and proposed mechanisms for polymorphic transitions in crystals. On the basis of the investigation of polymorphic transitions i...read more

Mechanism of Several Solid−Solid Transformations between Dihydrated and Anhydrous Copper(II) 8-Hydroxyquinolinates. Proposition for a Unified Model for the Dehydration of Molecular Crystals
Samuel Petit,Gérard Coquerel +1 more
TL;DR: In this article, an attempt to describe solid−solid transformations between copper(II) oxinates of known structure is presented, at a molecular level, and it is shown that the dehydration of the stable dihydrated form (β) takes place with the transmission of structural information from the parent to the daughter phase, so that a coherence is maintained.

Polymorphism of glycine, Part II
Elena V. Boldyreva,V. A. Drebushchak,T. N. Drebushchak,I. E. Paukov,Yu. A. Kovalevskaya,E. S. Shutova +5 more
TL;DR: In this article, the results of a systematic study of the transformations of the polymorphs of glycine into each another, including the effects of temperature, of the mechanical treatment and of various gases on the transformations, are summarized.

Reversible phase transitions in a buckybowl monolayer.
Leo Merz,Manfred Parschau,Laura Zoppi,Kim K. Baldridge,Jay S. Siegel,Karl-Heinz Ernst,Karl-Heinz Ernst +6 more
TL;DR: Like penguins on ice, buckybowl molecules move closer together when cooled on a copper surface (see model of a corannulene molecule adsorbed on Cu(111) for a model of how this affects the density at room temperature.
