Talk:Colloidal crystal/GA1

GA Review[edit]

Article (edit | visual edit | history) · Article talk (edit | history) · Watch

The article needs major rewriting to reach GA level. Things to do:

1) Copyedit. The text lacks coherent flow of sentences and many of them defy common sense. Just to give few examples:

1st sentence: "A colloidal crystal is a highly ordered array of particles that are formed in varying sizes (from a few millimeters to one centimeter)" - reads as nonsense: particles are formed (where?) in cm sizes.
2nd sentence: "A natural example of this phenomenon .." what phenomenon? We were talking about object, i.e. crystal.
".. in the gem opal, where the parts of pure spectral color result from close-packed domains of colloidal spheres" - parts of color .. result in a crystal ??
3rd sentence: "The spherical particles precipitate in very siliceous pools" - very siliceous? How comes siliceous covers all colloidal crystals?
And this all is trying to define a basic object.

** Note: Most of these comments are erroneous, insulting and inaccurate. This is what I typically get from this editor. The reference to "nonsense" is an example of the destructive and non-cummunicative level of criticism. -- logger9 (talk) 22:05, 14 September 2009 (UTC)[reply]

"two-dimensional triangular lattice, while a body-centered cubic structure" - cubic lattice can not be triangular.

etc. Then I would clarify numerous jargon, such as kT, etc and provide missing wikilinks.
2) Define the subject. Mention how it relates to and differs from usual crystals
3) Describe its basic properties: composition, morphology, stability, chemical, mechanical, electrical, optical, etc., properties. Especially important is to discuss how the individual particles and their regular arrangement contribute to those properties.
4) Look around for appropriate pictures. There are plenty on WP and commons.
5) Return to the lead and rewrite it to summarize the article.
6) Provide references and format them. Although I would encourage using "cite journal" and "cite book" templates, this is not obligatory. What is required though is (i) doi links for journals (ii) ISBN and page numbers for books.

This is a minimum, after which a review can start. Good luck. Materialscientist (talk) 03:55, 28 August 2009 (UTC)[reply]
