Welcome to Wikipedia. We appreciate your contributions, but in one of your recent edits to Silicon carbide, it appears that you have added original research, which is against Wikipedia's policies. Original research refers to material—such as facts, allegations, ideas, and personal experiences—for which no reliable, published sources exist; it also encompasses combining published sources in a way to imply something that none of them explicitly say. Please be prepared to cite a reliable source for all of your contributions. You can have a look at the tutorial on citing sources. Thank you.

Hello, I'm Padgriffin. I noticed that you made a change to an article, Nuclear isomer, but you didn't provide a source. I’ve removed it for now, but if you’d like to include a citation to a reliable source and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. Padgriffin Griffin's Nest 08:22, 23 April 2021 (UTC)
