Equilibrium properties

Structure and environment effects

Because of the strong dependence of the physical and chemical properties on the atomic structure of nanoalloys, it is of prime interest to describe properly their different thermodynamic equilibrium phases, for what concerns structure/morphology and chemical ordering. This new type of size-dependent “phase diagram” is complex to determine for nanoscaled “bimetallic” systems, either weakly or strongly miscible, where the surface effects can be overwhelming. However, to be more realistic: therefore it is important to take into account the environment in which the nanoalloys are embedded. This can be a support, a solid matrix or a fluid medium (gas, liquid), which influences the nanoalloy structure and properties. Finally, the addition of a third metal brings a new degree of freedom to tune structure and chemical ordering of nanoalloys, increasing the complexity and the richness of the structural landscape and giving rise to new challenging problems both on the experimental and the modelling side.
