Talk:Synthetic diamond/GA1

GA Review
The edit link for this section can be used to add comments to the review.''

After a quick scan I've found some MOS issues, listed below. I have not given the article a full review yet, and will wait until the major MOS issues are resolved before doing so.
 * Introduction The lead paragraph is too short (see WP:LEAD for more info). The lead should be a summary of the entire article, any information which is in the intro should be found within the main body as well. I find it is easiest to just take snippets from each paragraph (or in the case of longer articles such as this one, perhaps every other paragraph) and put the most interesting and pertinent information into the lead. Also, valid redirects to this page should be listed in bold type, not italics. Alternative names which are not redirects from other pages should not be bolded or italicised. Another point, the first sentence should not describe the article title as a "term", it should tell us what a synthetic diamond is.

The intro is still too small. --ErgoSum88 (talk) 17:24, 5 May 2009 (UTC)


 * Images Problems with image stack-ups, especially in the lead. Also, image sizes should not be specified unless absolutely necessary. I would suggest not coding all the images together in one big stack, but instead, sprinkling them throughout the prose as well as alternating them from left to right (but only when possible, without placing them directly under 1st level headers, 2nd and 3rd are OK). It is good to place images next to relevant prose, but only if there is sufficient space to do so. Remember, some users may have large screens resolutions which will cause images which are coded on top of each other to stack up, introducing large gaps in the text. For more info, see MOS:IMAGES.

On second thought, the lead image and images of detailed diagrams may be sized larger to allow better viewing, but normally no larger than 300px, so I changed some of them around so it would look better. --ErgoSum88 (talk) 17:24, 5 May 2009 (UTC)


 * Units Temperature and size units should be converted using the convert template. This will ensure accurate conversion between metric and standard units. BUT... converting units is not necessary for scientific articles (see Formation and evolution of the Solar System), so simply listing the metric units is sufficient. This is not to say that you cannot provide conversion of units for this article, to enable better understanding by the lay reader, but if you choose to do so you should use the template.


 * Links Wikilinks should only occur upon the first mention of the subject, and subsequent mentions of the word should not be linked. Linking words in the intro, and upon first mention in the body is OK, but third and fourth mentions should certiainly not be linked. There is still consensus-building regarding the linking of dates, but I am fine with it so I will let that one slide.


 * Text There are numerous one-sentence paragraphs which could be consolidated with other paragraphs. It is ok to have one-sentence, or short paragraphs, but they should be used sparingly and normally are used for emphasis.

I fixed some. Note that journal citations do not need access date and publisher. Regarding cite journal, I prefer using much shorter style, which is much easier to type and read in plain text (cf. the codes of this and this  references;  note that most GAs have ~50 of them and that cite journal is very sensitive; e.g., Title instead of title will be ignored), but I shall change it to cite journal if required? This is a non-issue. NIMSoffice (talk) 00:26, 5 May 2009 (UTC)
 * Refs References should be properly formatted using the various cite, cite book, and cite web templates. At the bare minimum, they should include an accessdate, publisher, author name (if available), URL or book title, and date of publication (if available). I also spot some statements which are not cited. If a single reference is used for an entire paragraph, one can simply cite it at the end of the paragraph. The standard format is to place the cite at the end of sequence of statements which are supported by the reference, or the end of a paragraph, whichever comes first. It is also not required to place citations within the introduction (unless the statement is controversial or being challenged, which I don't think we have that problem here), providing the information is repeated (and referenced) within the body of the article (which it should be anyway, MOS requires that the intro be a summary of the article, e.g., no information in the lead that is not within the main body).


 * The cite journal template should be used. I agree that the simpler form is easier to use and read, but it makes it easier and clearer to future editors who might need to use or modify the refs. You are right that they dont need publisher and accessdates, though, I was just trying to say they need the minimum fields to be filled out. Also, for future reference, citations should be placed after punctuation, not before (this includes commas and parentheses). I have taken the liberty of fixing this problem for you, but if you see any I have missed, please change them. --ErgoSum88 (talk) 17:24, 5 May 2009 (UTC)

I think I have covered everything, and I haven't even given the article my "thorough" review yet. On second thought, this probably would have qualified as a quickfail, as it might take longer than seven days to fix all the issues. But the seven day limit is mostly a suggestion and as long as I receive a reply within seven days I am willing to overlook the time limit. If an editor has not expressed an interest in addressing these issues within seven days, that is usually when I fail the article. So... good luck! --ErgoSum88 (talk) 15:25, 3 May 2009 (UTC)

Reading the article, I have come across some issues, listed below.


 * GE diamond project "In 1941 an agreement was made between General Electric (GE), Norton and Carborundum to further develop diamond synthesis." - Who are Norton and Carborundum?
 * ✅ They are companies, rather famous around that time (not now).


 * Later developments "Another successful diamond synthesis was produced on February 16, 1953 in Stockholm, Sweden by the QUINTUS project of ASEA (Allemanna Svenska Elektriska Aktiebolaget), " - Some explanation of what the "QUINTUS" project is would be nice.
 * ✅ Code name of top-secret project.


 * Ultrasound cavitation - Is this an emerging field of diamond production? This section seems awfully small for something that seems so promising. If this is true, perhaps some mention of the "newness" of this field might help the reader who wonders why this section is so lacking.
 * ✅ There are very few methods of growing diamond, and thus every one deserved mentioning. However, it is Ok to delete the whole section.
 * No, no, the section should stay. I think it is fine now that you have fixed the problem. --ErgoSum88 (talk) 00:53, 7 May 2009 (UTC)

I have also made numerous minor edits to the article to improve readability and understanding. Although I have taken care not to change anything I didn't understand, please check to be sure I haven't changed anything I shouldn't have. --ErgoSum88 (talk) 19:38, 5 May 2009 (UTC)
 * Your help is really appreciated ! NIMSoffice (talk) 07:45, 6 May 2009 (UTC)

Very well done. And thanks for adding the proper cite templates, it looks much better now. Good job, article passed, and here is your green circle! --ErgoSum88 (talk) 00:53, 7 May 2009 (UTC)

I believe 1882-1922 is 40 years, not 30... though I cannot find the correct information to clarify it. Syhon (talk) 13:17, 20 October 2009 (UTC)
 * History section note: "...he spent 30 years (1882–1922)..."
 * Thanks. Fixed. Materialscientist (talk) 09:45, 21 October 2009 (UTC)
