Question about Air sensitive sample holder
by Helen Chen 26 Mar '25

26 Mar '25

Hello, Our group (Jerry Seidler) just started a project involving doing VTC and HERFD on Yb doped CrX3 material. They are thin small crystal sheets and are very air sensitive. We have tried encapsulated them between a layer of laptop tape and film, but after 12hr we see degradation due to air leaks. I am looking for some advice on air sensitive sample holder. What are some typical methods you use to deal with air sensitivity, especially for samples in thin sheets geometry? Thank you

Athena - LCF component export error
by miranda.vu＠lightsource.ca 10 Mar '25

10 Mar '25

Hi, I am having an issue with the export of LCF data in Athena version 0.9.26. When I export the .lcf of files, it will re-order the components without properly re-ordering the associated data columns. The data and components will plot correctly in Athena before exporting. Is this something that can be fixed? Or if not would it be possible for me to get version 0.9.24 if you still have a copy of it? Please let me know if there is any additional information that I can provide. Thanks, Miranda

01 Mar '25

Hi all, I was following this article about Li2TiS3 https://urldefense.us/v3/__https://pubs.acs.org/doi/full/10.1021/acs.inorgc… and found this Ti edge XANES figure [image: image.png] The authors claim The peak position for LTS-213 is approximately 4970 eV, which agrees well > with that for rutile TiO2 with a valence of titanium species in the 4+ > oxidation state. Should we use the pre-edge to determine the oxidation state? Is it reliable, or should we use E₀ and compare it with … [View More]
