I noticed that you have posted comments in a language other than English. At the English-language Wikipedia, we try to use English for all comments. Posting all comments in English makes it easier for other editors to join the conversation and help you. If you cannot avoid using another language, then please provide a translation into English, if you can. If you cannot provide a translation, please go to the list of Wikipedias, look in the list for a Wikipedia that is in your language, and edit there instead of here. For more details, see Wikipedia:Talk page guidelines. Thank you. Materialscientist (talk) 10:51, 2 January 2024 (UTC)

Hello, I'm Materialscientist. I noticed that you added or changed content in 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. You can have a look at referencing for beginners. If you think I made a mistake, you can leave me a message on my talk page. Thank you. Materialscientist (talk) 10:51, 2 January 2024 (UTC)
