[edit] Solution (Terminology)

I hope this is the right place for this comment. The term Solution is a synoymn for the terms Chemical Solution, within the field of Chemistry, and Business Solution, within the field of Information Technology.

Within the field of Business and Information Technology (IT) a Solution is defined as some combination of tangible and/or intangible product(s) that address a business problem.

Currently, there is a redirection from Chemical Solution to Solution. I believe that the redirection should be from Solution to Chemical Solution and to Business Solution. The redirection from Chemical Solution to Solution be removed so the article that is currently in Solution reside on the Chemical Solution article. This will accomodate these two terms and refer to the appropriate term in the appropriate field.--Davidmarten223 11:47, 27 September 2006 (UTC)

[edit] Phosphate

I am new to the WikiProject Chemistry, so please correct me if this is not the right place to discuss this. I noticed the new WikiProject Chemistry info boxes on the talk pages of chemistry articles and think they are a great addition. My question is: if there is no rating for quality or importance scale yet, may I add one if I feel I know the topic well enough? Or should I discuss it first? Where? On the talk page of the corresponding article or rather on this page here? In case of the phosphate article I suggest an importance level of 'mid'. Thanks, --Splette Image:Happyjoe.jpg Talk 17:34, 31 August 2006 (UTC)

Welcome! Certainly have a go at assessment according to the criteria, and importance if you are familiar with the topic. I would rate phosphate as at least "High" importance IMHO because it is one of the major anions; we have many thousands of articles now (including some more specialised topics), and mid-importance is used for things more like caesium fluoride. See our list for more examples. Overall there are now over 70,000 articles on Wikipedia assessed using this scheme - please help it grow in chemistry. Many thanks!

[edit] Elements

You may know that I have been tagging the element talk pages, and adding assessments. I chose to classify the common elements like oxygen and iron as "Top-importance". As for the others, I figured that just by being an element (and thus a basic building block of chemistry), any of the others should rank as "High" importance. Is this OK? Or do you think elements like promethium should be only Mid? Feedback please? Thanks, Walkerma 01:16, 1 September 2006 (UTC)

They are all elements, and are equales in the PSE, but for wikipedia the overall importance of carbon is higher than of selenium and that is higher than that of Astatine. The how often a article is linked should give a good feeling if its really important. tausands (C) to more than 400 (Se) to over 100 (At)--Stone 07:22, 1 September 2006 (UTC)
I wouldn't object to having some of the less common elements marked as Mid-importance: promethium and astatine are obvious candidates, but I would include rubidium, scandium, tellurium, and most of the rare earths (sorry Martin...) My test would be "is there anything interesting about the element apart from the simple fact that it's an element?" Even an inorganic chemist such as myself can answer "No" to that one sometimes! :) Physchim62 (talk) 08:24, 1 September 2006 (UTC)

[edit] Chemistry COTM update

I'm not going to update the Chemistry COTM this month for two reasons.

  1. The current collaboration has not been worked on.
  2. The current nominations have only one person in support and, therefore, are not a collaborations.

Please help out by contributing. ~K 17:14, 2 September 2006 (UTC)

Yes, good idea. My limited experience with COTMs and the like is that sometimes there's a quiet period. I think we need to keep this going, though, even if we roll over the COTM for another month sometimes - once it gets established it'll work much better. I'm sorry I've done so little, but once version 0.5 is released (Nov?) I should have more time to help - I'm really missing working for WP:Chem! Walkerma 17:39, 2 September 2006 (UTC)

[edit] Caffeine

Our good friend caffeine is now featured, but still lacks the first total synthesis by E. Fischer!--Stone 13:17, 4 September 2006 (UTC)

[edit] Triphenylphosphine oxide

Hi guys

We don't have an article (or I haven't found one) on PPh3O yet. It's pretty ubiquitous, appearing often when triphenylphosphine is used in reactions. Is it worthy of a full article? Or a section in triphenylphosphine and a redirect to that page?

--Rifleman 82 18:43, 5 September 2006 (UTC)

I would give it a full article, it is thé sideproduct for the Wittig reaction! --Dirk Beetstra T C 18:50, 5 September 2006 (UTC)
Definitely worth a full article! I'll be cheering you on! I was going to write one, just never got around to it. Then again, I'm biased...! (no need to cite that!) Seriously, it is useful stuff, and linked from a lot of pages like phosphoryl chloride. Walkerma 19:22, 5 September 2006 (UTC)
Okay, I've done the easy part. Created the article, added the chembox, drawn the structure, copied in some data. It's not my area of interest so I'll need help to flesh out the article! --Rifleman 82 19:41, 5 September 2006 (UTC)

[edit] Uranium

There is a long-running dispute concerning whether uranium trioxide gas is a combustion product of uranium. I have found an expert, Dr. Carl Alexander at Battelle, with 45 years of experience in the subject, who claims that the research literature I have cited indicates that the gas is a combustion product. A handful of editors stridently opposing me have for several months claimed that the gas is not a combustion product, without any sources supporting that point of view. I ask that a neutral third party WikiProject participant please phone or email Dr. Alexander, at the number and/or address given at Talk:Uranium trioxide#Discussion from Wikipedia talk:WikiProject Chemistry, and ask him for the reasons he feels that the sources cited there support his and my view that uranium trioxide gas is a combustion product of uranium, and share his responses with all on Talk:Uranium trioxide. Thanks in advance. LossIsNotMore 03:22, 11 September 2006 (UTC)

[edit] Fuel cells and User:Mion

User:Mion started a Wikipedia:WikiProject Hydrogen, see also Hydrogen technologies. He created a number of categories and templates, like the monstrous Template:Sustainability and energy development group now on TfD.

Unfortunately I've got the impression, that his knowledge in the area is rather limited and his actions, as well-intended they may be, will make the affected articles worse, not better. In the moment, I'm struggling with his intentions to classify the osmosis cell as a fuel cell. He gives sources like a "PC magazine encyclopedia of IT terms" and the OED. Ouch.

Anyone interested to check his contris?

[edit] Combinatorial chemistry POV

I could use some help reverting POV in the Combinatorial chemistry article. I posted the origonal POV edit on the talk page. Thanks, ~K 03:58, 12 September 2006 (UTC)

[edit] Cahn-Ingold-Prelog priority rule

Hey guys, i have checked to this article as reference to my study but i found it a little bit confusing, could someone please enhance it or take a look at it?, I believe this article requires rephrasing some concepts to be easily understood for users non familiar with the topic.Cheers --HappyApple 03:32, 14 September 2006 (UTC)

I'll have a look at it this weekend, but no promises! Physchim62 (talk) 15:41, 15 September 2006 (UTC)


[edit] Gases

New here, but just noticed on the information panels for gases (e.g. http://en.wikipedia.org/wiki/Carbon_dioxide ) it gives density information, quoting relevant temperature. Shouldn't these also quote pressure? (I presume they're at 10000 Pa?)—The preceding unsigned comment was added by 131.111.121.243 (talk • contribs).

Hi! You presume right, it is in the bottom of the 'chembox' (stating: 'Except where noted otherwise, data are given for materials in their standard state (at 25 °C, 100 kPa). Infobox disclaimer and references', so actually, on the carbon dioxide page the 298K could have been omitted. Hope to see you around! --Dirk Beetstra T C 13:36, 19 September 2006 (UTC)

Wikipedia Assessments within AWB. Click on the image to see it in better resolution

Hi. If you still have work to do tagging talk pages and assessing articles, my AWB plugin might be of interest to you.

The plugin has two main modes of operation:

  • Tagging talk pages, great for high-speed tagging
  • Assessments mode, for reviewing articles (pictured)

As of the current version, WikiProjects with simple "generic" templates are supported by the plugin without the need for any special programatic support by me. I've had a look at your project's template and you seem to qualify.

For more information see:

Hope that helps. If you have any questions or find any bugs please let me know on the plugin's talk page. --Kingboyk 12:06, 20 September 2006 (UTC) PS You have a bug in your template: It's displaying a stray bracket at the end:

WikiProject on Chemistry This article is within the scope of WikiProject Chemistry, which collaborates on Chemistry and related subjects on Wikipedia. To participate, help improve this article or visit the project page for details on the project.

[edit] Diamagnetic anistropy

As far as I can tell we don't have an article on Diamagnetic anisotropy. Anyone want to take a stab at it? I don't know anything about the subject matter myself, merely that someone who does know about it thinks that there is a large oversight in not having any information on it. --69.138.178.196 19:52, 23 September 2006 (UTC)

[edit] Request for peer review of Enzyme kinetics

Hi there. Any feedback on this article to help bring it towards FA status would be a great help. Peer Review. Thank you. TimVickers 18:52, 25 September 2006 (UTC)

[edit] Articles for deletion

FYI: There are a few chemical stubs are up for deletion. See Wikipedia:Articles_for_deletion/Log/2006_September_25#1-Methylindole.2C_2-Bromo-1-chloropropane_and_5-Methylindole —The preceding unsigned comment was added by Olin (talk • contribs) 15:04, 27 September 2006.

[edit] Parabens

Earlier today I made an effort to improve the parabens article which was a real mess. There is a bit of controversy about the safety of parabens and I tried to cut out much of the commentary from both points of view. I did a bit of research and included references to some of the more relevant scientific studies representing both sides. I feel I made a vast improvement to the article, but shortly afterwards an anon IP came in and copy-and-pasted much of the older stuff back in, with edit summaries referring to my edits as " borderline vandalism" and "POV pushing". I realize that as a scientist I have a certain perspective, but can others please look at the article and help keep the article neutral and encyclopedic? Thanks. —The preceding unsigned comment was added by Edgar181 (talk • contribs).

There are concerns about the safety and chemistry of parabens. Take a look at the parabens article. Thanks. Welcomeall 22:52, 28 September 2006 (UTC)

[edit] Large portions of the parabens article have been erased.

Hello, There are two different editors which are both erasing entire sections of this article. Please oversight the history page and article.

I am a new user that does not know what to do in this situation. I think removing large sections of the parabens article may be vandalism.

http://en.wikipedia.org/w/index.php?title=Parabens&diff=78477710&oldid=78447944 Thank You. --63.17.32.188 19:23, 29 September 2006 (UTC)

You could read my explanation on the talk page of the article, or you could just discuss it with me. I've been making a good faith effort to improve the article as I have done to many, many other chemistry articles. If you try to talk to me you'll find that I am a reasonable person, I'm willing to listen. But so far all I've gotten is accusations of vandalism and edit summaries such as "SCREW YOU ED!" --Ed (Edgar181) 19:47, 29 September 2006 (UTC)
(edit conflict) This is not vandalism if the addition is inappropriate for the article, or does not adhere to the neutral point of view policy. "Inappropriate for the article" would be if the majority of the article is devoted to safety concerns - an encyclopedia on parabens should cover chemical and physical properties, how the compounds are manufactured and used, their biosynthesis and how they are metabolised. I reviewed some of the main scientific literature on this topic last night, and the consensus view (which is in effect NPOV) seems to indicate that the parabens are generally regarded as safe, but there are safety concerns that merit further research. Statements like this:
"Some marketers have alleged that there parabens are naturally made from plant sources such as blueberries, however, all parabens are entirely synthetic -- made with petroleum, and produced by the esterification of para-hydroxybenzoic acid."
do not sound like NPOV particularly as you don't cite a source (though to be fair, no citation was given to justify the removal). Checking a standard text on natural products, Mann's Secondary Metabolism, I see that para-hydroxybenzoate is a standard metabolite of shikimic acid, so it looks as if Ed's reversion was justified. To say that these compounds are "made with petroleum" rather blurs the truth, it implies that you add petroleum and get out methyl para-hydroxybenzoate! The editor performing the "vandalism" is a highly respected editor with a great track record and a PhD in organic chemistry (I also have an organic PhD), so any anonymous reversions of his work needs citations from the peer-reviewed literature to carry weight. If you have specific issues to raise this should take place on the Parabens talk page. Usually we resolve these disputes by a calm consensus, and I have always found Ed to be a very reasonable person. Also take a look at the Britannica or other encyclopedia entries for these compounds and see what we're missing. Walkerma 20:05, 29 September 2006 (UTC)

my comments:

  • get a user account, it is now impossible to tell who makes what edit
  • sign comments (easy: 4 tildes ~ in a row) impossible now to make sense of the paraben talk page who says what
  • No, other sources besides peer-reviewed literature are valid for instance websites American Cancer Society
  • it is a misconception to think that if something is not true it should not be covered in Wiki, if the tale is out it is Wikis job to debunk it.
  • if we leave Wiki to the PhD's little would get done and much would be considered inappropriate content, so lets continue to welcome non-PhD's to our pages

V8rik 20:36, 29 September 2006 (UTC)

All true, V8rik. I didn't mean to say that a non-PhD isn't welcome - just it's unreasonable to continuously accuse Ed of vandalizing pages. His wording seems (to me) to have been balanced carefully, and written intelligently. I also don't like to see one aspect of a compound take over the article page. Walkerma 02:12, 30 September 2006 (UTC)

I respectively disagee with some of Walkerma comments. Ed ERASED large portions of the parabens article and replaced it with his own one-sided BIAS preferred version. He erased information I constructively contributed to which my info is 100% Wikipedic. I have added information back to balance the article instead of the one-sided POV pushing at best and/or vandalism at worst. It is reasonable to tell the TRUTH. Check the history pages of the Parabens article for the clear EVIDENCE!!! --63.17.95.220 20:39, 30 September 2006 (UTC)

Providing evidence to support truths or facts is not sufficient for editing Wikipedia constructively. Edits must also be made which generally conform with the collaborative and cooperative spirt of the Wiki. Otherwise, the changes will simply be reverted or removed, regardless of their intellectual content. Please make an account to facilitate the collaborative process. I'll put that page on my watchlist, and if you have more questions about the Wiki, please feel free to come to my talk page for help. --HappyCamper 21:00, 30 September 2006 (UTC)
I am currently going through the document, trying to find a way to rewrite the safety sections (I am trying to find a way to get this into WP:NOT (the page is now mainly a safety-issue, more than describing the compounds). Also for me, Dene, if you have questions according to how to improve the article, according to the style guidelines (see e.g. WP:MOS, WP:EL and WP:NOT, don't hesitate to ask questions on my talk-page, or on the talk-page of paraben. --Dirk Beetstra T C 21:18, 30 September 2006 (UTC)
