“…The low E-values in the equilibrium melt, however, show that the present Pd-Cu-Ni-P melt is still far away from the hydrodynamic regime of uncorrelated binary collisions. This is in strong contrast to simple melts such as liquid Sn, which shows a rather large isotope effect [34]. Molecular dynamics simulations indicate a strong correlation of isotope effect and density of the liquid.…”

“…A µg experiment on liquid Sn revealed that well above the melting point convection even dominates the mass transport [40]. The µg data in liquid Sn obey D ∝ T 2 for temperatures between T m and 2 × T m .…”

“…A vanishing isotope effect indicates a collective transport mechanism involving a large number of atoms. In liquid Sn an isotope effect of about 0.4 has been reported, that is increasing with increasing temperature [40]. MD simulations on a binary Lennard-Jones liquid demonstrate that changes in the density in the order of 20 % only result in a continuous increase in E from 0 to ≃ 0.3 [47].…”

“…As has been shown by comparison of LC diffusion experiments on ground with experiments under microgravity conditions in space on liquid Sn [5,11], or with QNS measurements on liquid Cu [12], resulting LC values on ground are systematically larger by several 10% to 100%. The concentration profiles obtained on the Al-Cu systems measured here in situ do not show obvious influences of convective flow.…”
