Crystallization processes are used across the chemical, petrochemical and pharmaceutical industries. In the chemical industry, the potash and caustic industries use crystallization as a means to produce bulk chemicals and also as a separation technology for purification. The fine chemical and specialty chemical industries use crystallization processes to produce various high-value organic compo...

Chocolates consist of a suspension of fine cocoa solids and sugar particles dispersed in a continuous lipid phase in a process assisted by emulsifiers, usually a combination of lecithin and PGPR. In the conventional process, the tempering is a pre-crystallization step in which the melted mass is cooled at a controlled rate of temperature decay under continuous shearing action in order to organi...

A pronounced effect of overheating is observed on the crystallization behavior for the three zirconium-based bulk metallic glasses: Zr41.2Ti13.8Cu12.5Ni10Be22.5 , Zr57Cu15.4Ni12.6Al10Nb5 , and Zr52.5Cu17.9Ni14.6Al10Ti5 . A threshold overheating temperature is found for each of the three alloys, above which there is a drastic increase in the undercooling level and the crystallization times. Time...

Throughout the past few years the problem of solidification of a melt via nucleation has been addressed in colloidal systems mainly suspended in a fluid, which are known to undergo crystallization and have received considerably interest outside the colloid community. Despite the great deal of work, the microscopic details of the crystallization process are still not completely understood. A ver...

The ability to control the crystallization behaviour (including its absence) of particles, be they biomolecules such as globular proteins, inorganic colloids, nanoparticles, or metal atoms in an alloy, is of both fundamental and technological importance. Much can be learnt from the exquisite control that biological systems exert over the behaviour of proteins, where protein crystallization and ...
