The following article was marked as a stub since 3 years -
Particle aggregation in materials science is direct mutual attraction between particles (atoms or molecules) via van der Waals forces or chemical bonding. Particle aggregation is often spontaneous and involves one particle attaching to another particle or existing aggregate of particles. Particle aggregation occurs when particles come into close contact with each other. When there are collisions between particles in fluid, there is a chance that particles will attach to each other and become larger particle. There are 3 major physical mechanisms to form aggregate: Brownian motion, Fluid shear and differential settling.
- I replaced it by an alternative and substantially expanded text.
Thanks for your contribution but your edit left the article without an introduction. Wikipedia requires one. V8rik (talk) 16:35, 10 April 2012 (UTC)
See. I'm new to this. I reworked this entire intro, hope this one fits better. Pasting the old article upfront does not work too well, as that one went too quickly into rather specialized aspects. They are all taken up later in the new article. Williams12357 (talk) 18:29, 10 April 2012 (UTC)
Hi, thanks for the rewrite. The improved article still has a problem though. Ideally the article starts with a general definition and should describe the general scope and should then move on to specialised topics. Now the article has this order reversed V8rik (talk) 17:16, 11 April 2012 (UTC)
Presume you refer to the introduction. Adapted this one, fixed some minor issues, and moved the issue of stability and other systems (aerosols, emulsions) towards the end. If this is not what you meant, why don't you describe your concern more precisely or try to modify the article yourself. We can also leave it as is for a while to see if there will be more feedback.
