GSECARS Developed an Efficient and Affordable N95 Mask Disinfection System

Dr. Peter Eng with help from Mike Proskey and Dr. Joanne Stubbs, developed an efficient system of disinfecting N95 masks in large quantities.  This system will be invaluable for hospitals, factories, schools and offices as America re-opens during the current health crisis.

GSECARS Scientists Continue to Decode Moon's Mysteries 50 Years Later

Celebrating the 50th anniversary of the Apollo 11 moon landing, Argonne explores its early lunar research as it anticipates studies at the Advanced Photon Source of pristine moon rocks from the final lunar landing missions.

Diffraction at 13 BMC

Jin Zhang, an assistant professor in The University of New Mexico’s Department of Earth and Planetary Sciences, was recently awarded a NSF CAREER grant to pursue new research on the elastic anisotropy of mantle minerals and potential relationships with mantle flows.  Pictured here at 13 BMC.

X-ray Diffraction Patterns from a Diamond Anvil Cell.

X-ray diffraction is the most powerful technique for crystal structure determination. From left to right, patterns from a single crystal, polychrystalline, nano-cyrstalline and amorphous crystals.

Paris-Edinburg Press

The 180 ton Paris-Edinburg press combined with a multi-channel collimator to study structures of liquid silicates up to 12 GPa and 3000 K in 13-ID-C. The intense double focused monochromatic beam allows collection of X-ray scattering patterns with robust statistics in 5 minutes.

GSECARS
A national user facility for frontier research in the earth sciences using synchrotron radiation at the Advanced Photon Source, Argonne National Laboratory.

GSECARS provides earth scientists with access to the high-brilliance hard x-rays from this third-generation synchrotron light source. All principal synchrotron-based analytical techniques in demand by earth scientists are being brought to bear on earth science problems:
  • High-pressure/high-temperature crystallography and spectroscopy using the diamond anvil cell

  • High-pressure/high-temperature crystallography and imaging using the large-volume press

  • Powder, single crystal and interface diffraction

  • Inelastic x-ray scattering

  • X-ray absorption fine structure spectroscopy

  • X-ray fluorescence microprobe analysis

  • Microtomography

Future of COMPRES, GSECARS, and Synchrotron-Based Earth Science Research

Recently, NSF released a proposal solicitation for a new organization for management of synchrotron-based analytical capabilities for Earth and Environmental Sciences research and training. GSECARS is working with the larger Geoscience community to create a new and innovative organization in response to this call. More information about this effort can be found here.
