Hello, I'm Materialscientist. I wanted to let you know that one or more of your recent contributions have been undone because they appeared to be promotional.

Please stop adding inappropriate external links to Wikipedia. It is considered spamming and Wikipedia is not a vehicle for advertising or promotion. Because Wikipedia uses nofollow tags, additions of links to Wikipedia will not alter search engine rankings. If you continue spamming, you may be blocked from editing Wikipedia.
