Cold fusion and the use of deuterium palladium as a neutron source

Palladium's hydrogen affinity also allows it to capture deuterium, a stable, non-radioactive isotope of hydrogen. This makes palladium useful in devices which use high-voltage electrical potential to initiate nuclear fusion events, for the purpose of neutron generation. Neutron generators which utilize deuterium-saturated palladium and electrically driven fusion power reactions, have existed since the 1930's. Werner Schutze obtained U.S. patent 2,240,914 for a neutron-producing fusion tube, which employed a deuterium-saturated palladium plate, on May 6, 1941. Deuterium which has been absorbed into palladium's crystal lattice is termed Pycnodeuterium.

The section above was put into the article and for me it is dubious. You get neutrons from a discharge on deuterium adsorbed into the palladium? A real expert in nuclear physics has to have a look. --Stone (talk) 10:52, 10 March 2010 (UTC)

This does not require an expert. See Fusor and Muon-catalyzed fusion. Ever since the Pons and Fleischman experiment in 1989, the term "cold fusion" has been in disrepute. From the 1930s to the 1960s it was a serious subject of research, on the hypothesis that it might me an important energy source. Then in 1964 Philo T. Farnsworth perfected his Farnsworth Fusor, still considered an important laboratory device for generating neutrons with a cheap tabletop device. Teenagers have won science-fair competitions building these things. It's not that much different from building your own laser, or a model rocket that can go all the way up to the stratosphere. This is not "gee whiz" science. The kind of fusion involved is similar to what the sun had going for the first few million years: easily fusible deuterium, which occurs naturally in water. Nuclear bombs and the sun today involve something very different. Zyxwv99 (talk) 16:08, 12 June 2016 (UTC)

Regarding the origin of the name

I scarcely believe that it is inconsequential as to merit a bit more wording here, considering onomastic fields of study, or similar faculties of research nowadays. "What's in a name"? Kind regards --Nathan.aur8 (talk) 15:13, 16 August 2017 (UTC)

The trouble is that the name entails three levels of regress: "what was Pd named for" (the asteroid Pallas), "what was the asteroid Pallas named for" (the goddess Pallas Athena), and "who was Pallas Athena" (and how she got that epithet). After a while we appear to have wandered rather far from the original naming of the element: judging by the already known cerium and uranium, I am willing to bet that the chemists in question never thought about Uranus and Ceres the gods at all, but only the astronomical bodies named after them whose discoveries created stirs in the whole scientific community of the time. The extra detail is then not only extraneous but somewhat irrelevant, so I don't think it's a bad thing to get readers to click through again to find out about Pallas Athena.

You got a point there, I see. It is too many levels going down a tree in this context certainly. Thank you for the intelligible reply! --Nathan.aur8 (talk) 12:04, 17 August 2017 (UTC)

You are most welcome, and thank you for the enjoyable conversation! Double sharp (talk) 14:03, 17 August 2017 (UTC)

GA Reassessment

This discussion is transcluded from Talk:Palladium/GA2. The edit link for this section can be used to add comments to the reassessment.

This page has been tagged with citation needed / clarification needed tags for years, and there are many unreferenced paragraphs without tags that need to be referenced but aren't tagged. Even with WP:SCICITE in mind, the Applications section fails the good article criteria 2b. In addition, both the Compounds and the Applications sections fail the good article criteria 3b, as the article frequently goes on tangents that are either not important or not necessary to the palladium article, which causes the article to lose focus. WP:SUMMARY style would appear to be more effective for these two sections. Lastly, the tagged phrases should be taken care of at the minimum, with preferably at least one reference for every paragraph. Utopes _{(talk / cont)} 21:22, 23 February 2020 (UTC)

After no substantial improvement, and while still failing to reach the Good Article criteria, it is with a heavy heart that I will be demoting this Good Article. I hope to see this article return soon as a Good Article nominee. Utopes _{(talk / cont)} 02:50, 5 March 2020 (UTC)

configuration matter

I have a doubt most of other wiki pages (Malayalam, French) says electronic configuration is 2,8,18,18,0. I think it's good suggestion. because most of other element's (117) configuration end in 8 or less than 8. അമൽ ബെന്നി (talk) 06:32, 15 August 2021 (UTC)

It's exactly the same. The 0 can be present as an emphasis because the unoccupied 5s and 5p orbitals of Pd can be used in a chemical environment, but precisely because it's zero, it doesn't change the meaning. Double sharp (talk) 21:32, 14 November 2022 (UTC)

Change in class

I have reviewed this article, not good enough to be GA but it looks like it is good enough to be B, according to WP:ASSESS. — Preceding unsigned comment added by Keresluna (talk • contribs) 16:25, 21 October 2021 (UTC)

Palladium Toxicity / Absorption by the human body

Hello, I hope I am doing this in the right format. I am a PhD chemist who works as an organic chemist but this is my first time contributing to a discussion page on wikipedia.

The article says "Until that recent work, it had been thought that palladium was poorly absorbed by the human body when ingested". There is no citation given for this as far as I can tell. As an organic chemist I know just how much palladium is used in drug synthesis, if it is true that "recent work" has proved that palladium is indeed well absorbed by humans then that would have absolutely enormous implications, it would surely require a number of studies in to what the effects of this absorption are. Perhaps some studies have already been published, if so a summary of their conclusions should surely be cited.

Apologies again of if this is not the correct forum for placing these concerns, but my professional background made me feel compelled to address this issue. MorthosTheRed (talk) 20:52, 12 January 2023 (UTC)

good for you for following your instinctual feelings and posting your comment!! Thank you!! You shouldn't apologize for being compelled to speak up!! No one has the right to lay any conviction on how anyone feels. It's just nice to see someone stand up and speak freely Instead of not posting due to what others may think or feel or say. I am no better than the next person & the next person is no better than I. People tend to be so caught up in what others are going to do/say because you spoke truth. As long as you're feeling good about writing this, don't worry about what anyone else thinks. If they don't like it they're free to stop reading it and move on.. now, wouldn't THAT be the best!? Sorry for going off topic, just had to say - you keep doing what ya doing and speak up and be proud!!

I'm very taken by chemistry. Minerals, gems, soil, wish they offered that at school back in my day. I'm just hearing about palladium and saw this. So thank you for sharing as I'm trying to educate myself. Thank you.

Keep on doing what you're doing and don't worry about what anyone thinks, as long as no one is getting hurt and it makes you feel good, isn't that what matters. s.

😊😊✌️. There needs to be more people to do what they feel they should without worrying someone might not care for it.

You should be you and true to you because you gotta live with you until ya leave this world.

Ps. You have an incredible job as a chemist, if that were me, I'd be trying to figure out what EVERYTHING is compounded and made. Seriously. Anyway, enjoy ya job knowing at least someone is envious of the job you have 😁 peace and happy labbing!

and to those of you reading this if ya don't get it or don't like it, that's ok too, everyone has the right to their feelings, there is no right or wrong. See ya! 🤝Jewls💯real👍K 24.233.106.55 (talk) 04:11, 21 July 2024 (UTC)
