Here we discuss current theoretical knowledge of the manner in which intermolecular forces give rise to complex behaviour in supercooled liquids and glasses. An intriguing aspect of this behaviour is the apparen
supercooled liquidscoordination numberglass-formerWe study the significant entropy changes in supercooling and glass transition by developing a two (H and L) state cluster model, where the H-state represents the clusters with the coordination number z being larger than the reference size z R and ...
Crystals, Supercooled Liquids, and Glasses in Frozen Aqueous SolutionsAqueous solutions of HCl separate into nearly pure ice and eutectic "pockets" on cooling. The eutectic composition is near HCl · 6H 2 O and should crystallize below T ≈ 200°K. However, this material is easy to supercool ...
In this chapter we sketch some aspects of the physics of supercooled liquids and glasses. Starting with these materials may appear to be strange, but many properties of glasses and proteins are similar, and it is easier to recognize crucial properties of the dynamics in the less complex system...
This approach provides a very good description of the experimental data and identifies a predator-prey-like mechanism between crystal and amorphous, where the density variation acts as a blocking barrier. From a microscopic point of view, the structure of supercooled liquids and glasses is amorphous...
内容简介· ··· There has been a renaissance in glass science brought about by the development of concepts such as fragility index and the energy landscape with megabasins. Research on bulk metallic glasses has been explosive since their advent when MRS offered its first book on the topic....

Especially, in the cases of metallic glasses, the icosahedral order formation is considered to play an important role. To clarify the relation between the local structure formation and the relaxation behavior (or fragility) in the supercooled liquid states of metallic glasses, molecular dynamics ...
