Ostwald ripening crystals

Several other applications of nanosuspensions can be listed, such as the preparation of nanopolymer particles, days and composites, metal nanoparti-des, nanotubes and dispersions of carbon black for printing applications. All of these systems must be stabilised against aggregation, Ostwald ripening (crystal growth), and sintering. 

Assessment of Flocculation and Ostwald Ripening (Crystal Growth)... 

The second instabiUty problem in SC s is that of Ostwald ripening (crystal growth). There are several ways in which crystals can grow in an aqueous suspension. One of the most familiar is the phenomenon of Ostwald ripening , which occurs as a result of the difference in solubility between the small and large crystals [98],... 

At equilibrium, crystal growth and dissolving rates become equal, and the process of Ostwald ripening may now appear, in which the larger crystals grow at the expense of the smaller ones. The kinetics of the process has been studied (see Ref. 103). 

In principle, then, small crystals should show a higher solubility in a given solvent than should large ones. A corollary is that a mass of small crystals should eventually recrystallize to a single crystal (see Ostwald ripening. Section IX-4).

Because the onset of monomer-polymer equilibrium can occur before the filaments achieve their own equilibrium concentration behavior, these filaments will undergo polymer length redistribution. This is a slow process in vitro that in many respects resembles crystallization (See Ostwald Ripening).
