Liesel Schumann

[edit]

Hi, I wanted to ask whether you knew Liesel Schumann personally, or what your connection to her is—given that you created a Wikipedia entry about her? I am currently writing my master’s thesis on her and would be very happy to hear from you. Best regards, Amelie ~2026-58146-17 (talk) 10:11, 2 November 2026 (UTC)Reply

CdAl2S4

[edit]

Hi Materialscientist

You used to make pictures of crystal structures for commons and I have no idea if you still do or if I can better ask someone else, but if so, I have a request.

I was writing an article on af.wiki about CdAl
2
S
4
because it is the archetype of the E3 strukturbericht structure. It is also known as the Defect Chalcopyrite Structure and there is a bunch of compounds with this structure. I cannot find a picture of it on commons. Could you make one?

AFLOW has a CIF file of it. It is a relatively simple I4bar tetragonal

See: https://www.aflowlib.org/prototype-encyclopedia/A2BC4_tI14_82_bc_a_g-001/ Thanks Jcwf (talk) 17:34, 5 November 2026 (UTC)Reply

I can, but, I have a naive question: aflowlib allows free rotation. Why not taking a high-resolution screenshot? (The answer might help understanding what do you need in that crystal structure). They do have excessive whitespace, but I can easily remove it with Gimp. Cheers. Materialscientist (talk) 08:45, 6 November 2026 (UTC)Reply

Reversion of Madeleine Moon edit.

[edit]

you removed the edit I made on Madeleine Moon. My edit included naming of her sisters.... Source, she is my aunt! She is my mothers sister. What proof do you require? Because you seem to know more about Madeleine than her own family. ~2026-58853-77 (talk) 19:53, 5 November 2026 (UTC)Reply
