With a full set of experimentally obtained self- and interdiffusion coefficients, we are able to verify the relationbetween different transport coefficients in binary glass-forming Zr-Ni liquids. Despite a thermodynamic strongtendency of mixing, the interdiffusion is up to a factor of 2 slower than that predicted by the Darken equation.With the help of mode-coupling theory calculations, we identify that this is due to a slow, dominating kineticcontribution, arising from the dense packing of the melt, and the coupling of dynamics due to the strong Zr-Niaffinity.

Novel detection strategies were developed to improve the PGAA methodology in the analysis of bronze and brass objects. Instrumental neutron activation analysis and X-ray fluorescence were also involved in this study for comparison. [...]

Despite considerable research effort, the mechanisms of glass-formation are not well understood on the atomic length and time scale. While the metallic alloys showing the best glass-forming ability are multi-component alloys, the less complex binary glass-forming systems are attractive for studies aiming to find a microscopic understanding of the glass-formation process [...]

While spherical particles are the most studied viscosity modifiers, they are well known only to increase viscosities, in particular at low concentrations. Extended studies and theories on non-spherical particles find a more complicated behavior, but still a steady increase. [...]

Temperature-driven polyamorphism has been reported in various supercooled liquids and glasses. The dynamical and structural routes followed by the system during such crossovers are however not universal and appear to be related to intrinsic kinetic properties of the liquid. [...]
