Talk:Graphene

Add this paragraph to polycrystalline section
The hightened chemical reactivity of graphene grain boundaries makes polycrystalline graphene ideal candidates for chemical sensors. However, the presence of functional groups and impurities at the grain boundaries can alter the properties of the polycrystalline graphene. Grain boundaries functionalized by oxygen and hydroxyl group shows higher charge transport resistance. The adsorption of hydrogen atoms at the grain boundaries significantly reduces the strength of the polycrystalline graphene sheets. 111Seven (talk) 16:00, 19 October 2023 (UTC)
 * Specific text to be added or removed:
 * Reason for the change: I recommend to add the following sections to polycrystalline section where it discusses on the affect of functionalized groups on the properties of polycrystalline graphene. I think this will enhance the quality of the section.
 * References supporting change: doi=https://doi.org/10.1002/adma.201102663 (page 54, paragraph 2), https://doi.org/10.1021/jp311997j (page 3152, introduction paragraph 2 and 3), doi=https://doi.org/10.1002/adma.201401389 (page 5091, paragraph 1), doi=https://doi.org/10.1021/acs.jpcc.1c01328 (ref4: page 11147, abstract).
 * The page numbers from the sources where the information actually resides have not been provided. Surely the COI editor doesn't intend the reviewer to read more than 25 pages of text in order to verify the request. Please provide the actual pages where the information resides.

 * Thank you for reviewing this request. Here are the actual page numbers in the references that the information can found.(ref1: page 54, paragraph 2; ref2: page 3152, introduction paragraph 2 and 3; ref3: page 5091, paragraph 1; ref4: page 11147, abstract). 111Seven (talk) 12:30, 24 October 2023 (UTC)

Why is Graphene in this category? The article mentions nothing about it being toxic. Vid (talk) 22:19, 31 December 2023 (UTC)

Category: Graphene nanoribbons

 * The following paragraph is added to Graphene nanoribbons section:

Graphene nanoribbons may be classified as symmetry-protected topological insulators in the absence of disorder. Armchair nanoribbons display chiral symmetry and function as $$\mathbb{Z}_2$$ topological insulators, similar to graphene zigzag nanoribbons with zigzag edge states. Disorder, acting as a singular perturbation, alters the topological class to a topologically ordered insulator with universal topological entanglement entropy (long-range entangled). Additionally, midgap states with $$e/2$$ fractional charges exist, residing on opposite zigzag edges and displaying spin-charge separation.
 * Reason for the change:

Recent developments in topological aspects, including both symmetry-protected and topologically ordered features, are outlined. Key papers and books relevant to each aspect are cited.


 * it's not clear what changes you want to be made. Please mention the specific changes in a "change X to Y" format. ARandomName123 (talk)Ping me!  21:12, 15 January 2024 (UTC)


 * The change has been improved and been declared explicitly. Lehoanganh1112 (talk) 01:43, 16 January 2024 (UTC)
 * I'm not sure what is preventing you from making this edit yourself? Polyamorph (talk) 10:06, 5 February 2024 (UTC)
 * I was accused of adding promotional materials. The solution is to create a section in this Talk page. I appreciate it so much if you could review my proposal. Lehoanganh1112 (talk) 10:10, 5 February 2024 (UTC)
 * I have reviewed these proposed changes and suggest that you go ahead and make the proposed changes to the page. I fail to see any conflict of interest, or how that could impact this edit. I'd go for it. Sincerely, Guessitsavis (she/they) (Talk) 21:21, 5 February 2024 (UTC)
 * This was part of a pattern of self-citation across many articles. Adding cites to yourself in that way is in fact a conflict of interest. It should just be added without the final sentence/cite. MrOllie (talk) 21:25, 5 February 2024 (UTC)
 * Way too technical ("universal topological entanglement entropy"???) and out of scope for this article. We do have Graphene nanoribbons, though I'm not sure if it belongs there either, for the same reason. This article is already bloated and full of WP:REFSPAM hype.

Basics
A short paragraph description for lay people near the beginning would be helpful. Any suggestions? BlueBellTree (talk) 04:40, 20 June 2024 (UTC)
