Postdoctoral position opening
by Anatoly Frenkel 18 Jun '25

18 Jun '25

We will have an opening (pending final funding approval) for a Postdoctoral Researcher in my group — the *Structure and Dynamics of Applied Nanomaterials* at Stony Brook University. We are seeking a highly motivated scientist to explore the mechanisms of novel electromechanical materials, focusing on systems that exhibit non-classical electrostriction. This research builds on our recent work: 🔹 https://urldefense.us/v3/__https://pubs.acs.org/doi/full/10.1021/jacs.5c003… 🔹 https://urldefense.us/v3/__https://www.nature.com/articles/s41467-023-43032… The successful candidate will: ✅ Lead synchrotron-based experimental efforts ✅ Study the effects of stress, electric fields, and temperature on these materials ✅ Collaborate with international teams ✅ Leverage unique access to both Stony Brook University and Brookhaven National Laboratory Required: 🔹 Proven expertise in X-ray absorption spectroscopy (XAS) 🔹 Strong publication record Note: We are considering only candidates currently in the U.S. who are authorized to work. 📩 Interested or know someone who might be? Please reach out to me at anatoly.frenkel(a)stonybrook.edu. Anatoly ------------------------------------------------------------------- Anatoly I.

Larch for XES processing
by Morrell, Colin T. 15 Jun '25

15 Jun '25

Hello, I am new to the technique of XES and have been working out a way to analyze some XES spectra. I have used Larch in the past for XAS analysis and found a few places that indicated that larch is also capable of processing XES data in the LarchGUI application. I have been working to install a version or find how to do this and have not been successful. Have XES support been removed from the larch applications? Any help or clarification is greatly appreciated! Thank you in advance. Sincerely, Colin Morrell PhD Candidate | See Group Division of Chemistry & Chemical Engineering California Institute of Technology

XRFMap_viewer tricolor map legend
by Tian, Tony 07 Jun '25

07 Jun '25

Good afternoon, I was able to make a tricolor map with Larch's XRFMap_viewer like below, [cid:010cee66-2afd-4b58-8065-f70e947a2810] but couldn't have a pie-shaped diagram legend like this displayed like in a lot of XRF publications. Could you give some advice on how to do it? Thank you. [cid:95e76dd6-42ad-45f2-9498-8a664a065d64] Best regards, Tony

Hello~ all I opened the cif file in CIF Browser. I couldn't make feff.inp in this Browser. In a previous version, feff.inp was generated. However, it isn't now. What is the problem? I installed xraylarch in anaconda virtual system as following: (base) C:\>conda update --all (base) C:\>conda create --name xraylarch (base) C:\>conda activate xraylarch (xraylarch) C:\>conda install -c conda-forge python=3.9.10 (xraylarch) C:\>pip install torch (xraylarch) C:\>conda install -y -c conda-forge wxPython pymatgen scipy h5py matplotlib (xraylarch) C:\>conda install -y -c conda-forge openbabel tomopy (xraylarch) C:\>pip install epicsapps (xraylarch) C:\>pip install xraylarch (xraylarch) C:\>larch -m I have been using Window 10 system [image: image.png] Best regards, Eun-Suk Jeong

Question about Air sensitive sample holder
by Helen Chen 05 Jun '25

05 Jun '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
