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 and archived in the page history 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.

 * further to that, the problem is not just the lack of sources, but the nature of the content. Wikipedia is not a dictionary, so does not consist of lists of words or terms, and articles do not generally contain them. Especially not one so long and badly formatted as the one you added.-- JohnBlackburne wordsdeeds 05:59, 7 November 2017 (UTC)
