Homogeneous nucleation of phase transformations in supercooled water
Robert Felix Tournier
The classical nucleation equation, applied to two liquids, is completed by an additional enthalpy for solid supercluster formation governing the liquid and glass transformations. T…
First-order transitions in glasses and melts induced by solid superclusters nucleated and melted by homogeneous nucleation instead of surface melting
Robert F. Tournier
Supercooled liquids give rise, by homogeneous nucleation, to solid superclusters acting as building blocks of glass, ultrastable glass, and glacial glass phases before being crysta…
Predicting Glass-to-Glass and Liquid-to-Liquid Phase Transitions in Water using Classical Nucleation Temperature
Robert F. Tournier
Glass-to-glass and liquid-to-liquid phase transitions are observed in bulk and confined water, with or without applied pressure. They result from the competition of two liquid phas…
Predicting Glass-to-Glass and Liquid-to-Liquid Phase Transitions in Water
Robert F Tournier
Glass-to-glass and liquid-to-liquid phase transitions were observed many years ago in bulk and confined water with or without applied pressure. It is shown that they result from th…
Glass phase and other multiple liquid-to-liquid transitions resulting from two liquid phase competition
Robert F. Tournier
Melt supercooling leads to glass formation. Liquid-to-liquid phase transitions are observed depending on thermal paths. Viscosity, density and surface tension thermal dependences m…
Helium-4 Glass Phase: a Model for Liquid Elements
Robert F. Tournier, Jacques Bossy
The specific heat of liquid helium confined under pressure in nanoporous material and the formation, in these conditions, of a glass phase accompanied by latent heat are known. The…
Lindenmann Rule Applied to the Melting of Crystals and Ultrastable Glasses
Robert F. Tournier
The ratio of the mean square amplitude root of thermal vibrations and the interatomic distance is a universal constant dls at the melting temperature Tm. The classical Gibbs free e…
Crystallization of Supercooled Liquid Elements Induced by Superclusters Containing Magic Atom Numbers
Robert Felix Tournier
A few experiments have already detected the presence of icosahedral superclusters in undercooled liquids, confirming a possible homogeneous nucleation of such entities as suggested…
Fragile-to-fragile Liquid Transition at Tg and Stable-Glass Phase Nucleation Rate Maximum at the Kauzmann Temperature TK
Robert Felix Tournier
An undercooled liquid is unstable. The driving force of the glass transition at Tg is a change of the undercooled-liquid Gibbs free energy. The classical Gibbs free energy change f…
