Solute clustering and interfacial tension

The effect of surface curvature on surface tension has been included in the theory of homogeneous nucleation to show that, under certain conditions, cluster formation results in a decrease in Gibb's free energy. This cluster formation is thus a spontaneous event and a quasi-equilibrium concentr...

Description
Summary:The effect of surface curvature on surface tension has been included in the theory of homogeneous nucleation to show that, under certain conditions, cluster formation results in a decrease in Gibb's free energy. This cluster formation is thus a spontaneous event and a quasi-equilibrium concentration of clusters of narrow size range may then exist in supersaturated solutions. Previous experimental work suggests the existence of solute clusters in a variety of aqueous solutions. The implications for crystal nucleation and growth theory are discussed.
