Welcome!

Hello, ChengZhangWan, and welcome to Wikipedia! My name is Ian and I work with the Wiki Education Foundation; 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.

Dinitrogen cleavage

Hi - would you like me to move this to 'Dinitrogen cleavage' or another title? I can do that if you want. Blythwood (talk) 18:50, 6 March 2016 (UTC)

Several articles exist on the topic...

The title of your article is too complex. It reads like a college essay. Probably the way to go is to recast the article as "artificial nitrogen fixation" or "homogeneous nitrogen activation". Or even better, insert parts of your work into the existing articles Haber-Bosch process, Transition metal dinitrogen complexes, FeMoco, nitrogen fixation. Your sources look great.--Smokefoot (talk) 03:30, 9 March 2016 (UTC)

File source and copyright licensing problem with File:Silica supported tantalum hydride to reduce N2.png

File Copyright problem

Thanks for uploading File:Silica supported tantalum hydride to reduce N2.png. However, it currently is missing information on its copyright status and its source. Wikipedia takes copyright very seriously.

If you did not create this work entirely yourself, you will need to specify the owner of the copyright. If you obtained it from a website, please add a link to the page from which it was taken, together with a brief restatement of the website's terms of use of its content. If the original copyright holder is a party unaffiliated with the website, that author should also be credited. You will also need to state under what licensing terms it was released. Please refer to the image use policy to learn what files you can or cannot upload on Wikipedia. The page on copyright tags may help you to find the correct tag to use for your file.

Please add this information by editing the image description page. If the necessary information is not added within the next seven days, the image will be deleted. If the file is already gone, you can still make a request for undeletion and ask for a chance to fix the problem.

Please also check any other files you may have uploaded to make sure they are correctly tagged. Here is a list of your uploads. If you have any questions please ask them at the Media copyright questions page. Thank you. Steel1943 (talk) 04:08, 9 March 2016 (UTC)
