Kinetics of crystal nucleation in ionic solutions
... This study is concerned with three-dimensional nucleation in multicomponent electrolyte solutions. For the nucleation event to take place in solution, the dissolved ions have to come into contact to form pairs, clusters or aggregates. Association of ions is promoted by the tendency of an aqueous sol ...
