How to Contributeelectron diffraction pattern

27th Mar 2024 23:55 UTCLalith Aditya Senthil Kumar

Should we add the X-ray diffraction image to Icosahedrite, as it is the first recorded Quasicrystal?

If we should, could someone add the photo above to the page?

-Thank you, Lalith

Also, the existing photo for Icosahedrite contains Khatyrite, so it should be used for both.

What are the sources (journal/book/website citations) for these images? Are they copyrighted, and if so, does the copyright grant a license for this kind of use? They are worth having on Mindat, but that information is needed to know whether we can use them legally. If you created the images in your own lab, then you probably own the copyright and you can grant permission for Mindat to use them. If they were published in a journal article that you wrote, the journal publisher probably owns the copyright and would have to grant permission even though you created the images.

I found the first one on Wikipedia, and the second one comes from a public-use science journal.

we would still need the source references

Here are the source references, guys.

Just because wiki has it doesn't mean its automatically available.

I believe the photos of Icosahedrite are from:

Luca Bindi, Paul J. Steinhardt, Nan Yao, Peter J. Lu (2011) Icosahedrite, Al63Cu24Fe13, the first natural quasicrystal. American Mineralogist, 96, 928–931.

I think it does, as per terms of the licence for this file: https://commons.wikimedia.org/wiki/File:KhatyrkiteXRD.PNG

(ResearchGate is another matter however)

This image does not represent an X-ray diffraction pattern ('produced' in an X-ray diffractometer with an X-ray tube as the source), but an electron diffraction pattern (taken in a transmission electron microscope, with an electron gun as the source), which is something completely different. Please change the title of this thread accordingly.
