Welcome!
Hello, Zehuiwu, and welcome to Wikipedia! My name is Ian and I work with Wiki Education; I help support students who are editing as part of a class assignment.

I hope you enjoy editing here. If you haven't already done so, please check out the student training library, which introduces you to editing and Wikipedia's core principles. You may also want to check out the Teahouse, a community of Wikipedia editors dedicated to helping new users. Below are some resources to help you get started editing. If you have any questions, please don't hesitate to contact me on my talk page. Ian (Wiki Ed) (talk) 01:45, 20 January 2021 (UTC)

Hello, I'm Oshwah. I noticed that in this edit to Applications of nanotechnology, you removed content without adequately explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an edit summary. If this was a mistake, don't worry, the removed content has been restored. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you.  ~Oshwah~  (talk) (contribs)   09:16, 9 April 2021 (UTC)
