Transition temperatures of gold-silver alloys and free energy states. (a) Schematic diagram illustrating the solid-liquid transition temperature of bulk gold-silver alloys and the coalescence temperature of gold-silver alloy NPs against the composition, as well as the dominating factors for particle coalescence, and (b) a schematic of Gibbs free energy of metals at different scales, in which ΔG represents the difference in volume free energy and ΔG* is activation energy for particle coalescence.
