Journal ArticleDOI

First X-Ray Scattering Studies on Electrostatically Levitated Metallic Liquids: Demonstrated Influence of Local Icosahedral Order on the Nucleation Barrier

TL;DR: The first direct experimental demonstration of Frank's complete hypothesis is presented, showing a correlation between the nucleation barrier and a growing icosahedral short-range order with decreasing temperature in a Ti39.5Zr 39.5Ni21 liquid.
Journal ArticleDOI

Difference in icosahedral short-range order in early and late transition metal liquids.

TL;DR: This is the first experimental observation of distorted icosahedral short-range order in any liquid, although this has been predicted by theoretical studies on atomic clusters.
Journal ArticleDOI

Dynamic diamond anvil cell (dDAC): A novel device for studying the dynamic-pressure properties of materials

TL;DR: A unique device, a dynamic diamond anvil cell (dDAC), which repetitively applies a time-dependent load/pressure profile to a sample, which addresses the sparsely studied regime of dynamic phenomena between static research and dynamic shock-driven experiments.
Journal ArticleDOI

Curie-Weiss behavior of liquid structure and ideal glass state.

TL;DR: High energy X-ray scattering and electro-static levitation in combination with molecular dynamics simulation are used and it is shown that the height of the first peak of the structure function, S(Q) − 1, follows the Curie-Weiss law.
