Effect of Impurity on Critical Conditions of Colloidal Cluster Nucleation in Colloidal System

摘要: Due to depletion interactions, a few of colloidal spheres will be packed into cluster or clusters, even phase transition may take place if the volume fraction system is large enough. In binary system, mole one component very small, then it can taken as impurity other component. this work, effect on critical conditions nucleation was studied by Carnahan-Starling state equation and principle entropy maximum. The results show that, small-spheres obvious smaller than that so influence from huge cannot ignored. addition, also found larger is, density packed, however, size nucleating almost independent cluster.
