Paper with wrong enantiomer in a figure

In the following reference:

Quack, Martin; Seyfang, Georg; Wichmann, Gunther (2022). "Perspectives on parity violation in chiral molecules: theory, spectroscopic experiment and biomolecular homochirality". Chemical Science. 13 (36): 10598–10643. doi:10.1039/d2sc01323a. PMID 36320700.

it is stated in the caption of Fig. 8 that Sbromochlorofluoromethane is predicted to be lower in energy due to parity violation, but in the figure the wrong enantiomer is shown on this side. Which enantiomer is more stable, according to the original sources for this data? –LaundryPizza03 (d) 08:18, 28 December 2024 (UTC)[reply]

Where can I find data on the circulation and citation rates of these journals?

Hello everyone, To write an article about a scientist, you need to know, where can I find data on circulation and citation rates of journals from this list? Vyacheslav84 (talk) 09:58, 28 December 2024 (UTC)[reply]

There is more than one "D. Trump" who has published a scientific paper. Your search is too broad, and returns papers by multiple distinct individuals.
Some of them are actual Donald Trumps, like the American oncologist Donald Lynn Trump.
Others have different names, nationalities, and genders—like the English genetics expert, Dorothy Trump.
You will need to be more specific in your search. TenOfAllTrades(talk) 01:43, 12 January 2025 (UTC)[reply]

So-called “Hydrogen water”

I saw an ad promoting a device which presumable splits water into hydrogen and oxygen and infuses water with extra hydrogen, to a claimed surplus of perhaps 5 ppm, which doesn’t seem like much. I found a review article which looked at several dozen related studies that found benefits:https://pmc.ncbi.nlm.nih.gov/articles/PMC10816294/ .

I’ve noticed that carbon dioxide or chlorine (chloramine?) dissolved in water work their way out pretty easily, so I wonder if dissolved hydrogen could similarly exit hydrogen enriched water and be burped or farted out, rather than entering the blood stream and having health benefits. is it more than the latest snake oil? Edison (talk) 23:01, 28 December 2024 (UTC)[reply]

Yes, the dissolved hydrogen will exit the water just as quickly (even faster, because of its low molecular mass and complete lack of polarity or capability for ionic dissociation), and even if it does enter the bloodstream, it will likewise get back out in short order before it can actually do anything (which, BTW, is why deep-sea divers use it in their breathing mixes -- because it gets out of the bloodstream so much faster and therefore doesn't build up and form bubbles like nitrogen does) -- so, I don't think it will do much! 2601:646:8082:BA0:209E:CE95:DB32:DD64 (talk) 01:50, 29 December 2024 (UTC)[reply]
It's conceivable it might take out the chloramine, I guess. I don't think there's very much of it, but it tastes awful, which is why I add a tiny bit of vitamin C when I drink tap water. It seems to take very little. Of course it's hard to tell whether it's just being masked by the taste of the vitamin C. --Trovatore (talk) 02:12, 29 December 2024 (UTC)[reply]
If you just want to split water into hydrogen and oxygen all you need is a battery and two bits of wire. You don't say where you saw this ad but if it was on a socia media site forget it. Shantavira|feed me 11:47, 29 December 2024 (UTC)[reply]
If this so-called hydrogen water was emitting hydrogen bubbles, would it be possible to set it afire? ←Baseball Bugs What's up, Doc? carrots14:03, 1 January 2025 (UTC)[reply]
We once had an article on this topic, but see Wikipedia:Articles for deletion/Hydrogen water. Graeme Bartlett (talk) 22:27, 1 January 2025 (UTC)[reply]
I don't know if it is rubbish or not but a quick look on the web indicates to me it is notable enough for Wikipedia. I didn't see anything indicating it definitely did anything useful so such an article should definitely have caveats. I haven't seen any expression of a potential worry either so it isn't like we'd be saying bleach is a good medicine for covid. NadVolum (talk) 23:07, 1 January 2025 (UTC)[reply]
International Journal of Molecular Sciences does not sound of exceptionally high quality. DMacks (talk) 01:05, 2 January 2025 (UTC)[reply]
