Hello, I'm Materialscientist. I noticed that you made a change to an article, but you didn't provide a reliable source. It's been removed for now, but if you'd like to include a citation and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you. Materialscientist (talk) 22:37, 16 December 2012 (UTC)

Hello, I'm Materialscientist. I noticed that you recently removed some content without explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an edit summary. If this was a mistake, don't worry, I restored the removed content. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks! Materialscientist (talk) 22:37, 16 December 2012 (UTC)
