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. Advertising and using Wikipedia as a "soapbox" are against Wikipedia policy and not permitted; Wikipedia articles should be written objectively, using independent sources, and from a neutral perspective. Take a look at the welcome page to learn more about Wikipedia. Thank you. Materialscientist (talk) 08:59, 19 September 2020 (UTC)

Please do not add promotional material to Wikipedia. While objective prose about beliefs, organisations, people, products or services is acceptable, Wikipedia is not a vehicle for soapboxing, advertising or promotion. Thank you. Materialscientist (talk) 09:52, 19 September 2020 (UTC)
