Deviation from high-entropy configurations in the atomic distributions of a multi-principal-element alloy
Louis J. Santodonato,Yang Zhang,Mikhail Feygenson,Chad M. Parish,Michael C. Gao,Richard Weber,Joerg C. Neuefeind,Z. Tang,Peter K. Liaw +8 more
TL;DR: It is shown that, even when the material undergoes elemental segregation, precipitation, chemical ordering and spinodal decomposition, a significant amount of disorder remains, due to the distributions of multiple elements in the major phases.
Detection of First-Order Liquid/Liquid Phase Transitions in Yttrium Oxide-Aluminum Oxide Melts

TL;DR: At very high temperatures, yttria-alumina melts show a first-order transition, previously inferred from phase separation in quenched glasses, which is shown how the transition coincides with a narrow and reversible maximum in SAXS indicative of liquid unmixing on the nanoscale, combined with an abrupt realignment in WAXS features related to reversible shifts in polyhedral packing on the atomic scale.
Acoustic levitation: recent developments and emerging opportunities in biomaterials research
Richard Weber,Chris J. Benmore,S. K. Tumber,Amit N. Tailor,C. A. Rey,Lynne S. Taylor,Stephen R. Byrn +6 more
TL;DR: Recent developments and applications of acoustic levitation in materials R&D are reviewed including implementation and results of experiments on supercooled and supersaturated liquids using an acoustic levitator at a high-energy X-ray beamline.

Structure of high alumina content Al2O3-SiO2 composition glasses.
TL;DR: It is proposed that the structure of the glass is a "transition state" between the alumina-rich liquid and the equilibrium mullite phase that are dominated by 4- and 6-coordinated aluminum ions, respectively.
