This article was the Wikipedia:Chemistry Collaboration of the Month for Nov 2006. The article has went through quite a few revisions since. From a scientific point of view, it does cover the important parts. The field is too broad for the article to be exhaustive. How about from a non-technical point of view? Tone? Style? Examples? Pictures? Please comment! --Rifleman 82 22:51, 1 December 2006 (UTC)[reply]
