message: Hi all, I'm thinking of submitting Cyclol to be a featured article candidate and I'd really appreciate your suggestions and insights before I do that.  Strictly speaking, the topic is more biochemistry than chemistry, but it might interest some of you here nonetheless.  Thanks for your help! :) Willow 17:54, 8 November 2006 (UTC)
replies: text: Thanks, those are all good suggestions!  I'll try to fix those up today or tomorrow and then submit for peer review. The "scientific method" part was indeed tricky to write, but I think it's a valuble part of the article for our readers. I've found analogous passages in the Britannica as well, so I don't feel too guilty. ;) Willow 19:52, 9 November 2006 (UTC)
replies: text: I never said to pull the scientific method completely! However, I can guess your PoV from the way it's written, which is not ideal for an article. I will see if I can make a few more concrete suggestions on the article talk page. Physchim62 (talk) 10:04, 10 November 2006 (UTC)

message: An excellent editor of scientific articles, Opabinia regalis, is being considered for adminship.  Her work has primarily been in biochemistry, but she is broadly educated and scientifically discerning, which could catalyze the development of science articles on Wikipedia.  Please support her candidacy, if you feel as I do that she would an excellent administrator. Willow 19:45, 9 November 2006 (UTC)

message: Hi everybody, I was feeling bold, so I made some small changes to the portal. Feel free to yell at me tell me what you think about them; I've made some suggestions on the portal talkpage which would probably need to help of more experienced contributors to carry out. Thanks! riana_dzasta 10:55, 12 November 2006 (UTC)

replies: text: Thanks, here as well as at Portal talk:Chemistry. All constructive edits are welcome at the portal—otherwise it will die from lack of use! Physchim62 (talk) 17:36, 13 November 2006 (UTC)
replies: text: Hey, I left a message on the portal talk page 3 days ago about changes I made in my sandbox, but no reply! Oh well... I went ahead and implemented them on the main page. Feel free to tell me if they're really bad... :) riana_dzasta 03:53, 17 November 2006 (UTC)

message: Hi all, you were great in the scientific peer review of Cyclol — thanks!  I tried to make the changes that you recommended and I submitted it this morning to be a featured article candidate.  So if you have other helpful criticisms — or unabashed Support ;) — now's the time to write!  Thanks again, Willow 22:45, 13 November 2006 (UTC)

message: Hello everyone - I came across something while reading Louis Pasteur's accomplishments which suggested that there are exactly 9 compounds from which enatiomeric crystals can be formed which are big enough to separate with the naked eye. Does anyone know what these nine compounds are? --HappyCamper 01:44, 14 November 2006 (UTC)
replies: text: Well tartaric acid is obviously one! I am more than sceptical about this claim—whose crystal growth techniques, whose naked eye? The number of potential candiades is infinite, maybe only nine have actually been observed... Physchim62 (talk) 08:08, 14 November 2006 (UTC)

text: I think 1,1-binaphthol may be one, I read a paper (years ago) on its crystals being separated. Walkerma 08:16, 14 November 2006 (UTC)
replies: text: In the Pasteur expt, a solution of the racemic acid yielded macroscopic crystals that were each optically pure, a spontaneous separation in a sense, instead of each crystal being composed of a mixture of enantiomeric molecules. That's more (maybe lots more?) of a trick than just being able to grow a giant single-enantiomer crystal starting from a single enantiomer in solution. DMacks 08:26, 14 November 2006 (UTC)
replies: text: Agree completely: in the case of Pasteur's experiment it only worked because of a cold spell in Paris (the equilibrium temperature between the enantiomeric and racemic crystal forms is around 23 °C, from memory). I still think it is going a bit far to say that there are exactly nine compounds where the enantiomeric crystals are more stable (at which temperature?): it is not as if we are talking of platonic solids here! Physchim62 (talk) 08:52, 14 November 2006 (UTC)

text: Everything there, except the original Pasteur exeriment, involves doing something to promote one enantiomer to crystalize preferentially or somesuch, no "spontaneous resolution". Do tartaric acid crystals have macroscopic mirror-image shapes, or is the only detectable difference their optical activity? DMacks 17:55, 14 November 2006 (UTC)

message: Hope this is not out of place. I think this topic is quite important but it is only mentioned in Homochirality and On water reaction, without a full topic of its own. Anyone can chip in? --Rifleman 82 20:02, 15 November 2006 (UTC)
replies: text: Sadly not, but its an important topic, anyway even catalysis, which is a broader concept, needs a lot of work Knights who say ni 00:06, 16 November 2006 (UTC)

message: I've created a new template for chiral synthesis:
The intent is to group the main concepts relating to chiral synthesis together, to show connectivity, rather than looking at each topic piecemeal. There are currently several redlinks and a redirect link. I think the presence of the redlink will cause the article to be created eventually.
I've added these to the See also sections of the various articles. Are there any comments, + or -, about the suitability, etc? Reason I'm asking is that the template from crystallization, and I wonder if there are any other objections, etc. --Rifleman 82 15:14, 25 November 2006 (UTC)

message: I do not see any of the chemists involved with Wikipedia:Articles for deletion/List of chemical compounds with unusual names . The page List_of_chemical_compounds_with_unusual_names complies with Wikipedia:Unusual_articles so not against Wiki policies. Although the page is not original, at times childish it is relevant to how chemists name their chemicals and I do not want to leave it to the non-chemists to make the decision V8rik 21:30, 26 November 2006 (UTC)

message: Hi wikichemistry community, i have been trying to look up for Lipscomb rules on inorganic chemistry to understanding the nature of the chemical structure of boranes, but it seems nobody has written an article on such a subject. I would deeply appreciate someone can summarize or adding at least the equations to know the values of p,q,s,t,x,y (involved on boranes structure). By the way, would someone could add the Cleanup tag or Expand on Boranes page?, i found it a little bit short to understand the nature of the boranes. Thanks for reading my query, Cheers :).--HappyApple 03:26, 27 November 2006 (UTC)
