Information icon 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) 09:41, 11 January 2023 (UTC)Reply

Wikipedia's technical logs indicate that this IP address or network has been used to disrupt Wikipedia. It has been blocked from editing to prevent further abuse.
If you are not the intended target of this block, please read the information below in order to receive assistance.
Wikipedia tries to be open, but we sometimes must block IP addresses to prevent editing by abusers, vandals, or block evaders. These blocks can affect users who have done nothing wrong. If you are a legitimate user, follow the instructions below to edit despite the block. Users who are the intended target of a range block may still appeal the block.

IP users (without an account): If you do not have an account and wish to bypass this block, an account can be created to allow you to edit. In general, these blocks only prevent users who are not logged in from editing; once you are logged in, the block will no longer affect you in any way. To request an account, simply click here and follow the directions provided on the page. It is important that you use an e-mail address issued to you by your ISP, school, or organisation, so we may verify that you are a legitimate user. When filling out the account request form, please refer to this block in the "comments" input field. If you've been instructed to request an account via email, please refer to this block in your message.

Registered users (with an account): Please make sure you are logged in to your account. If you are unable to edit while logged in, you may request IP block exemption to bypass blocks unconnected with you that affect your editing. Post an unblock request to your user talk page.
Administrators: Checkusers have access to confidential system logs not accessible by the public or administrators due to the Wikimedia Foundation's privacy policy. You must not loosen or remove this block, or issue an IP block exemption, without consulting a checkuser or the Arbitration Committee. Administrators who undo checkuser blocks without permission from a checkuser or the Arbitration Committee may be summarily desysopped.
