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 need guidance on referencing, please see the referencing for beginners tutorial, or if you think I made a mistake, you can leave me a message on my talk page. Thank you.

Probably you should also read WP:PEACOCK, WP:COATRACK and WP:COI, all of which have relevance to your earlier edit.--JBL (talk) 15:06, 25 February 2014 (UTC)
