Interface engineered surface morphology evolution of Au@Pd core–shell nanorods

The surface morphology evolution of Au@Pd core–shell nanorods was controlled by adjusting the solution supersaturation.

Kinetic and Thermodynamic Precipitation Parameters of the Pb-Sn Solid Solutions

Stages of cellular precipitation for the supersaturated Pb-Sn solid solutions were analyzed. This was done for almost the whole homogeneity interval. Literary heritage as well as the data of the present authors concerning kinetic and thermodynamic parameters of cellular precipitation for these solid solutions were compared and summarized. It was shown that the segregation factor, which characterizes the impurity atoms behavior at the grain boundary, decreases with solid solution supersaturation increase.

The Influence of Fluoride on the Seeded Growth of Apatite From Stable Supersaturated Solutions at pH 7.4

Previous studies have shown that fluoride affected the formation of apatite in spontaneous precipitations from unstable calcium phosphate solutions partly through its effect on the stability of such nonapatitic precursors as octacalcium phosphate, Ca 8H2(PO4)6-5H2O. The present study shows that fluoride had a comparable effect on the seeded growth of apatite from stable solutions when the degree of solution supersaturation favored the transient development of octacalcium phosphate precursors on the seed surface.
