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.
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.
Update on status and plans at GSECARS, August 25, 2020
Please note the following information:
Current APS guidance for the 2020-3 run mandates that external users will not be allowed on-site. Based on this current policy, GSECARS is only scheduling users for 2020-3 that can mail-in samples, with partial or full remote access to control selected beamline computers to perform experiments in-close collaboration with GSECARS beamline staff.
Users that wish to have remote computer access to run their experiments at GSECARS will be considered “Remote Users” and noted so on their ESAF. “Remote Users” are still required to have all their APS safety training up to date for ESAF approval, ANL site access must be current and an approved 593 in place for foreign nationals.
Contacting beamline staff prior to your experiment is required. This can be arranged either via email, phone, or online (Zoom or Bluejeans are preferred).
Samples should be sent to your primary beamline contact at least one week ahead of scheduled beamtime. Please send the shipment tracking number to your host. We recommend FedEx as the most reliable option for shipping samples.

GSECARS is 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

Latest Happenings at GSECARS
The GSECARS 13 ID-D DAC program successfully ran 140 mail-in DACs and 10 ambient samples. They received (and returned!) 36 boxes of DAC samples. Users report that running experiments remotely with mail-in samples resulted in excellent data and was deemed a great success!
Dr. Mark Rivers at GSECARS hosts a virtual hands-on tutorial sessions on synchrotron computed microtomography.
Christofanis will be working on software development for the Diamond Anvil Cell program.
Sector 13 LVP users have successfully completed their most recent experiments remotely. They were able to mail in their samples, and with the help of remote access software, and GSECARS staff, run their experiments.
CNN, CNET and APS highlight work done at 13 IDD by Dan Shim’s Lab for Earth and Planetary Materials at Arizona State University and scientists from the University of Chicago on how the interiors of carbon-rich exoplanets could create diamonds through high pressure and temperature conditions.
