Steps in solution growth: dynamics of kinks, bunching and turbulence

The effect of cation:anion ratio in solution on the mechanism of barite growth at constant supersaturation: Role of the desolvation process on the growth kinetics

“…These findings were corroborated by crystal growth experiments performed in water-methanol solutions (25% MeOH), where observed morphological changes were attributed to a reduction of the kinetic barrier for barium ions to approach the surface. Nevertheless other workers showed experimentally that cations and anions behave similarly with respect to the growth kinetics Chernov et al, 2005Chernov et al, , 2006Nehrke et al, 2007).…”

Predicting crystal growth by spiral motion

“…One method, which has been used by Chernov (1984) and Winn & Doherty (1998) to determine the critical length of a spiral edge, is to predict the size of a two-dimensional critical nucleus using a classical Gibbs-Thomson approach. The critical length of a spiral edge is then assumed to be equal to the critical length for that same edge on an equivalent hypothetical two-dimensional nucleus.…”

The effect of specific background electrolytes on water structure and solute hydration: Consequences for crystal dissolution and growth

“…Therefore even when the sulfate anion has a lower affinity for water than the barium cation, the energy expense of stripping water molecules which hydrate a barium-terminated kink at the surface will affect anion incorporation rates. Such an approach may provide an explanation for the common observation that the maximum rate of crystal growth occurs at a solution composition corresponding to stoichiometry of lattice ions in the crystal, suggesting equal frequencies of attachment for equally charged building units in spite of their different hydration characteristics Chernov et al, 2005;Chernov et al, 2006;Rashkovich et al, 2006;Nehrke et al, 2007). Growth velocity can be more dependent on water dynamics around an ion in cases where the growth process is controlled by diffusion rates towards the surface due to the fact that ionic diffusion depends of frequency of solvent exchange (Lynden-Bell and Rasaiah, 1997).…”
