Review My WebApp
Adrenalist: This is a really interesting/fascinating webapp. A few suggestions. 
1. Improve the design / User Interface. It's a bit clunky and diminishes the experience. 
2. Make the search field auto-complete. Use jQuery and you could have it done in a few minutes. I am not a chemist, so I don't know the exact spelling of most chemicals or elements. http://jetlogs.org/2007/10/22/jquery-auto-suggest-with-keyup...
