Hello, I'm Materialscientist. I wanted to let you know that I reverted one of your recent contributions—specifically this edit to Pedro A. Sanchez—because it did not appear constructive. If you would like to experiment, please use the sandbox. If you have any questions, you can ask for assistance at the Teahouse or the Help desk. Thanks.

Please do not add original research or novel syntheses of published material to articles as you apparently did to Pedro A. Sanchez. Please cite a reliable source for all of your contributions. Thank you. Materialscientist (talk) 23:12, 17 October 2023 (UTC)
