Journal ArticleDOI
First X-Ray Scattering Studies on Electrostatically Levitated Metallic Liquids: Demonstrated Influence of Local Icosahedral Order on the Nucleation Barrier
Kenneth F. Kelton,Geun Woo Lee,Anup K. Gangopadhyay,Robert W. Hyers,T. J. Rathz,Jan R. Rogers,Michael B. Robinson,D. S. Robinson +7 more
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.
Geun Woo Lee,Anup K. Gangopadhyay,Kenneth F. Kelton,Robert W. Hyers,T. J. Rathz,Jan R. Rogers,D. S. Robinson +6 more
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
Materials properties measurements and particle beam interactions studies using electrostatic levitation
Paul-François Paradis,Takehiko Ishikawa,Geun Woo Lee,Geun Woo Lee,Dirk Holland-Moritz,Jürgen Brillo,Won-Kyu Rhim,Junpei Okada,Junpei Okada +8 more
TL;DR: In this article, the authors describe the principle of electrostatic levitation and retrace the development of various facilities throughout the world, focusing on the advances made by each research group.
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.
Chae Woo Ryu,Chae Woo Ryu,Wojciech Dmowski,Kenneth F. Kelton,Geun Woo Lee,Geun Woo Lee,Eun Soo Park,James R. Morris,James R. Morris,Takeshi Egami,Takeshi Egami +10 more
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.
