Your GA nomination of Fiveling

The article Fiveling you nominated as a good article has passed ; see Talk:Fiveling for comments about the article, and Talk:Fiveling/GA1 for the nomination. Well done! If the article is eligible to appear in the "Did you know" section of the Main Page, you can nominate it within the next seven days.

Professor, I wonder if I can pick your brain around this article http://dx.doi.org/10.1016/j.addma.2022.103351 (figure 6). Does it relate to fiveling and the authors did not figure that out, or I am just confused? FuzzyMagma (talk) 22:33, 9 June 2024 (UTC)

Give me a few days please -- travelling in southern Australia. Ldm1954 (talk) 09:03, 10 June 2024 (UTC)

@FuzzyMagma, their section 4.4.1 is all fivelings and friends such as the related Ic; as you thought they did not make the connection. You can find particles such as their bi-icosahdron of Fig 14 in Journal of Crystal Growth 54(1981) 433—438 & 61(1983) 556—566. I also published similar growth in Thin Solid Films, 136(1986) 309 315. Whether it is Ic growth as they suggest or Dh/poly particles is not clear to me; HREM would help.

N.B., need a good Ic page on WP, Todo list.

N.N.B., the idea of icosahedra etc in liquids is quite old, older than many of their cites. Ldm1954 (talk) 23:58, 15 June 2024 (UTC)

Thanks Professor. I think the novelty is that these are not observable in wrought austenite but now being observed in different FCC additively manufactured alloys including Nickel. FuzzyMagma (talk) 05:41, 16 June 2024 (UTC)

The standard rationale for these shapes is surface energy anisotropy, as against the liquid phase ordering they mention. I have only dabbled in AM, so I am not sure how to get anisotropy, as I did not think the undercooling was high enough. If there is impurity surface segregation that might work. Evidence?

N.B., such discussions might be better off WP. Ldm1954 (talk) 07:25, 16 June 2024 (UTC)

About S.Y.H. Su article

Thank you for visiting the article and your comments. I will try to dig out more infomation as you suggested.

I want to point out S.Y.H Su commenced his career in 1967 much before the age of internet. He retired quite a while ago. That is a signficant disadvantage in terms of the Google Scholar H index. Also, as you know, in some fields, the paper production and citation count can be significantly lower than in other fields. Incidentally he added Stephen to his name sometime after finishing his PhD. Thanks. Malaiya (talk) 23:03, 29 May 2024 (UTC)

Help needed to fix the Wiki page

Vladimir Lumelsky here: In response to Ldm54 comments on my unfinished Wiki page: you said, you need proofs, say on my being the journal's founding editor-in-chief or my former Yale Univ. professorship - but how and where can I add this information? Say, regarding my journal editorship, the journal's cover's backpage says that very clearly - can I send you or put in a photo of it - if so, how, is it enough? For my Yale professorship, after your comment I've called Yale, they sent me an email confirming that fact, with the time range - how can I get to you this proof? I'd much appreciate your response. Thank you. Lumelsky (talk) 11:52, 10 June 2024 (UTC)

You don't prove to me, you have to prove to readers.

• For the editorship you put in an appropriate journal cite.
• For Yale their email is no good as this is not verifiable by all readers. Maybe use wayback and find an old page they have that shows you, or some conference announcement.

Nonmetal hatnote

I've had an interaction over Nonmetal already and I concluded the hatnote was correct but the article has the wrong name, see Talk:Nonmetal#Nonmetal_elements?. It's basically an article like say Group 3 element about some elements. The chemistry content is ok but the rest is just a pile of factoids about some elements. Since there are a couple of committed editors involved I decided to move on. Some day I will work on nonmetal (physics) and look at the issue again. Johnjbarton (talk) 02:10, 12 June 2024 (UTC)

WP:BEBOLD. I just went through cutting out some clear errors and added some tags to Nonmetal. Removing a paragraph/sentence here are there does not need to be first raised in talk unless it is contraversial.

The Nonmetal (physics) page is awful. Maybe we should have "Nonmetallic phases" and just rewrite and rename. Ldm1954 (talk) 10:44, 12 June 2024 (UTC)

The nonmetal (physics) stub was added last week, I believe in response to my complaint that the topic article nonmetal should either include physics or be renamed "nonmetal elements" with an additional "nonmetal (physics)". Johnjbarton (talk) 15:28, 12 June 2024 (UTC)

The general topic of the article is fine and standard chemistry; I agree with you that they wander way off topic and have added a long list to the talk page. You will see that I included your term for it in the 1st sentence.

I rewrote the stub which is now Nonmetallic compounds and elements. Feel free to add to it or change it. Later some of the links to Nonmetal can be changed. Ldm1954 (talk) 18:25, 12 June 2024 (UTC)

N.B., you may want to comment on my RfD to move Nonmetal back to Nonmetal (chemistry), perhaps in an hour or so. Ldm1954 (talk) 19:41, 12 June 2024 (UTC)

Good luck with your efforts. Topics related to periodic table, nonmetals, metalloids are often the domain of editors who are rather territorial and do not subscribe to contemporary views (say, Shriver and Atkins) of chemistry and materials science. --Smokefoot (talk) 14:36, 18 June 2024 (UTC)

Smokefoot: Periodic table and Metalloid are encyclopedic FA articles, based on reliable sources rather than personal views lacking WP:NOTABILITY.

I'm attempting to apply the same approach to Nonmetal despite the non-encyclopedic views of OPs. Wait! "Great God, could it be(?)": Shriver & Atkins are mentioned in both Metalloid and in Nonmetal!

Dear Sandbh: please keep it up with Shriver and Atkins. A good resource for learning.--Smokefoot (talk) 16:33, 19 June 2024 (UTC)
