Welcome!
Hello, Yemengshan, 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. If you have any questions, please don't hesitate to contact me on my talk page. Ian (Wiki Ed) (talk) 17:13, 21 September 2017 (UTC)

For students writing for Wikipedia
Please rely on WP:SECONDARY or WP:TERTIARY, i.e. Wikipedia mainly seeks material supported by references to books and reviews. Wikipedia is a source of fairly general info. It is not Chemical Reviews and does not aspire to be. So keep your content general. Otherwise you risk having it removed for being overspecialized. --Smokefoot (talk) 13:29, 12 October 2017 (UTC)

Double-exchange Mechanism
1. In the first sentence of the first paragraph, the previous editor wrote: "The double-exchange mechanism is a type of a magnetic exchange that may arise between ions in different oxidation states." However, the double-exchange can also happen between two ions which have the same oxidation state. For example, in [4Fe4s]+ clusters, we can divide this cluster into two pairs: [2Fe2S]0 and [2Fe2s]+. In [2Fe2S]0, the oxidation states for two Fe are both +2, but they can still experience double exchange and gives a spin state of S=4.

2. The organization or the structure of this paper is in a mess.

EG: Mengshan, #1 is very good. #2 is okay, but please explain why; how is it a mess, and what should be done with it? WritingMan (talk) 15:53, 16 March 2018 (UTC)

Anammox
I fixed the dead link, which is the 9th reference, in anammox.

Topic Choice
1. Morris reagent (or ketamine hydrochloride testing reagent) -- found from "article requested"

Ketamine hydrochloride is a medication mainly used for starting and maintaining anesthesia. However, because of its help to relieve pain, some people abuse this. And since ketamine hydrochloride is tasteless, odourless and colorless, it will not be discovered when added to drink, which may facilite se assault. So it's important to find a way to test it. Morris reagent is such a test reagent to test even trace ketamine hydrochloride. I searched some paper about this and found various methods to test it, in which morris reagent is not the only way. I think I'll create a word which is Ketamine hydrochloride testing reagent.

2. Triphenylmethyllithium -- found from article requested

My previous experience with organic lithium salts stays in n-butyl lithium and t-butyl lithium. It's my first time to see an aromatic lithium. So I want learn more about this while writing this topic.

3. Benzophenone Imine -- proposed by myself

This is one chemical I'm using now in my project. I thought this is a very common reagent since it's one example in Buchwald couping, a famous reaction. So it surprised me when I found there is no introduction to this in wiki. So I want to write some for this.

Ways to improve Benzophenone imine
Hi, I'm Lithopsian. Yemengshan, thanks for creating Benzophenone imine!

I've just tagged the page, using our page curation tools, as having some issues to fix. Needs quite a bit of work. Might be best to go back to the sandbox rather than risk getting deleted from mainspace.

The tags can be removed by you or another editor once the issues they mention are addressed. If you have questions, you can leave a comment on my talk page. Or, for more editing help, talk to the volunteers at the Teahouse.
