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, the removed content has been restored. 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) 11:46, 6 December 2012 (UTC)

Please stop your disruptive editing. If you continue to blank out or remove portions of page content, templates or other materials from Wikipedia, you may be blocked from editing. Thank you. Materialscientist (talk) 06:18, 8 February 2013 (UTC)
