A Crystallisation Phenomenon

Crystallisation in a granular material

The athermal and dissipative nature of packings of grains is still challenging our understanding of their compaction as well as their crystallisation. For instance, some beads poured in a container get jammed in random disordered con gurations, which cannot be denser than 64%, the random closed packing (RCP) limit. Remarkably it has been suggested that the RCP bound is saturated with dense patt...

Crystallisation kinetics

D. Quigley (Theory Group) The rates at which crystals nucleate and grow from either a supercooled melt, or a supersaturated solution, are essential inputs for solidification models in a variety of contexts. These include materials synthesis and processing, development of antifreeze strategies for cryopreservation, and understanding the formation of harmful biological crystals such as kidney st...

KNOWCAT: A Tool For Knowledge Crystallisation

Modelling the butterfat crystallisation process

Milk fat exhibits seasonal variations in composition and properties which are undesirable for many subsequent applications. Thus techniques are sought to process dairy products in order to achieve a consistent quality. A brief introduction to milk fat presents its most important particularities, especially composition, seasonal variations, solid fat content, crystallisation and polymorphism. Th...
