Query: Effect of the Composition on the Free Energy of Crystal Nucleation for
  CuPd Nanoalloys   Using molecular simulation, we study the nucleation process from supercooled
liquid alloys of Cu and Pd. The simulations reveal a complex interplay between
the size of the crystal nucleus and its composition that greatly impacts the
crystallization process on the nanoscale. In particular, we find that the free
energy of nucleation strongly depends on the composition of the alloy, with a
free energy barrier for the equimolar alloy that is more than two times larger
than for the pure metals. We attribute this increase in free energy to the
variations in composition occurring both at the surface and in the core of the
nucleus. The local changes in composition are then analyzed by comparing the
surface energies of the two metals and by taking into account the competition
between crystallization and demixing that takes place at the interface between
the nucleus and the surrounding liquid.
