Untitled[edit]

I renamed this page Belousov-Zhabotinsky reaction after doing a Google test on the various possible spellings of the second name (Zhabotinsky, Zhabotinskii, Zhabotinski). --Jose Ramos 09:15, 4 Oct 2003 (UTC)

the article gives the impression that these are not an established phenomenon and remain unexplained... i assume this is not the case? - Omegatron 18:44, Jan 3, 2005 (UTC)

German?[edit]

A German-speaking chemist (or one who knows enough German to use the Babelfish translator) might take a look at this article[1] in the German Wiki. The illustrations look more helpful.

Original references[edit]

I've added two references that are usually cited when referring to the BZ reaction in scientific papers. Unfortunately numerous different versions of citations are being used, probably because people confuse volume and page numbers of translated versions with the original. Although I do not have access to the journals, these references are the ones that seem most trustworthy. Hendrik Fuß 10:33, 5 June 2007 (UTC)[reply]

Ref. 5 doesn't seem to work anymore. Any possible alternative(s)? — Preceding unsigned comment added by 76.21.156.227 (talk) 05:27, 19 December 2012 (UTC)[reply]

nonequilibrium biological phenomena[edit]

The statement "they provide an interesting chemical model of nonequilibrium biological phenomena" maybe true, but no explanation or example is given. 66.111.125.85 (talk) 01:26, 14 June 2014 (UTC)[reply]

Does it follow conservation of Energy?[edit]

Apparently the system look like a perpetual motion machine that does not exist. Kindly explain why this system is not a perpetual motion machine?? and how this continuous change never stops? Thanks in advance.

Brief answer: Only some of the species present have oscillating concentrations (for awhile). There are other species present whose concentrations evolve in one direction only, so the system as a whole does not return to its previous state, and the system does obey the laws of thermodynamics. See Chemical oscillator#Theory.
A more complete answer would include the detailed reaction mechanism, and list which components oscillate and which evolve in one direction only. With references of course.Dirac66 (talk) 03:14, 15 January 2019 (UTC)[reply]

Needed more mathematical details of thermodynamics and kinetics.[edit]

Needs more elaboration of thermodynamics, kinetics and mechanism of this strange phenomenon.

12 years an orphaned gif[edit]

The lovely animation File:The Belousov-Zhabotinsky Reaction.gif appears to be a self-propagated orphan. The file description says its source is on Nitori's Journal which was moved and is now deadlinked, but the archived site says: This implementation is based on the work of Nitori Kawashiro, and uses a dynamic image to visualize the state of the simulation. Nitori Kawashiro is a pseudonym/screenname unless its a name of someone who only publishes in non-Latin-script journals (which is a possibility) -- otherwise the name apparently doesn't exist in any other academic context (formal or informal). The rest of the page and source code cites no journal articles or authors as sources. @Simpsons contributor: is the uploader and hasn't been active in several years. The code also has a live implementation but no better description.

It appears the most significant contributors to this article for the past decade have been IPs, but this is a general call out to anyone who is familiar or wants to dive the literature: does this code have a published origin, or is it an editor's OR?

Hi there, that is my image. And no, I am not called Nitori, she was a factional character! Simpsons contributor (talk) 09:09, 28 August 2022 (UTC)[reply]
I figured as much, as I also figure you don't literally contribute to the production of The Simpsons. It's a beautiful animation, but could you provide the publication(s) or research you used to get the propagation equations you used for the source code?
