LARCH Workshop, XAFS2022
GSE beamline scientist Matt Newville presented a session at the LARCH Workshop, XAFS2022, ” The XAS Viewer application and Larch for X-ray Absorption Spectroscopy”.
Exploring Silicon’s Effect on Earth’s Core
High temperature (“hot”) [a] and quenched (“cold”) [b] integrated XRD patterns from burst heating run D1P2S3 (49-56 GPa), color-coded by temperature. Colored ticks below patterns identify reflections from hcp-Fe0.8Ni0.1Si0.1 (pink), fcc-Fe0.8Ni0.1Si0.1 (purple), and KCl (black). The sluggish fcc to hcp back-reaction can result in reflections from remnant fcc grains in patterns quenched from temperatures above the hcp-fcc transition.

Frustrated Antiferromagnet Jarosite Collapses under Pressure
Frustrated Antiferromagnet Jarosite Collapses under Pressure: Researchers using the U.S. Department of Energy’s Advanced Photon Source and National Synchrotron Light Source II investigating the pressure-temperature phase diagram of jarosite at pressures up to 121 GPa found that it’s antiferromagnetic magnetic order di
Space odyssey: Argonne scientists among the first to study asteroid fragments
Using X-ray techniques, scientists will study tiny specks of asteroid 162173 Ryugu, collected by a Japanese space mission. Learning more about how this asteroid formed will further our understanding of the solar system, including Earth’s formation.
Carbonate-induced Melting in the Deep Upper Mantle
Carbonate-induced Melting in the Deep Upper Mantle: This research, carried out at the U.S. Department of Energy’s Advanced Photon Source, will foster a better understanding of the role of carbon in the Earth’s geochemical and geophysical systems.
