Talk:Spinodal decomposition

message: Many equations here are image files, but mathematics should be written using formula code. I found these formulas on :commons:category:Particle physics, where they clearly not belong. So please convert, and have these images deleted. /Pieter Kuiper (talk) 15:39, 6 June 2009 (UTC)

replies: text:  Thanks, guys ! Sorry, but I don't know the math codes yet (I am just a lowly materials science engineer), so I had a desktop publisher create the images to save time. I have a regular email dialogue going with Dr. John Cahn, who I met some 25 years ago at a grad school seminar. We will be meeting again soon on the UW Campus in Seattle to discuss his latest theories and current experiments, where he is pulling glasses from the melt and attempting to show that the glass transition is an example of the first-order phase transformations in solids. Wish me luck :-) -- logger9 (talk) 18:57, 8 June 2009 (UTC)
thread_title:  Equations should be in math code 

message: I fixed the equation D=\mu\partial f/\partial{c} , figuring it was just a typo, but it was reverted.  I'm not going to change what is there now, but I'll explain the issue.  In instances where \mu is used, the relative chemical potential is implied. 
From  
:J = - D \nabla c = - M \frac{ \partial ^2 f } { \partial c^2 } \nabla c  
we're saying that D=M\partial^2f/\partial c^2.  We know that \partial f/\partial c = \mu from the differential of the free energy  (this is stated several lines down in the article), and so
:D = M \frac{\partial \mu }{\partial c}.    
This derivative of the chemical potential with respect to concentration is proportional to what is called the thermodynamic factor.  A lot of the notation looks like it was pulled from the review by Hilliard, but I can't point to that for this, because he doesn't actually include this relation.
Aside from that, there are some inconsistencies in notation (e.g., confusion between \mu and M for mobility  and an instance where f is used where c is meant).  It seems like people are keeping tabs on this article, so I won't mess with it.  Just thought it should be cleared up so as not to mislead anyone who is new to the subject.

thread_title:  Math issues 

message: The introduction lists two characteristics of spinodal decomposition -
# Numbered list item it has a sound theoretical basis
# Numbered list item it leads to practical applications.
While the first point appears to be explored fully (the math is impressive if obtuse to most of us), the second point appears to be given no development whatsoever.
Finally, today's (10-Nov-2011) announcement of a Kyoto prize for Dr. Cahn should be added to the article.  — Preceding unsigned comment added by 98.237.176.169 (talk) 16:23, 10 November 2011 (UTC)
thread_title:  Applications / Awards 

message: It seems from an outsider's perspective that this page has significant overlap with the Lower Critical Solution Temperature and Upper Critical Solution Temperature pages. As far as I can tell, the concepts and physics are the same but this page refers mostly to mineral and metal systems while the other two pages refer mostly to organic systems. It would be nice to see them somehow connected. I only know as much as I've read from the pages though so I'm not at all qualified to actually do it.  — Preceding unsigned comment added by 73.229.125.70 (talk) 21:02, 4 September 2015 (UTC)
thread_title:  Relationship to LCST and UCST pages 

message: "Becker and Dehlinger had already predicted a negative diffusivity inside the spinodal region of a binary system."
Is there a reference that clearly supports this statement?Wikibearwithme (talk) 07:41, 24 December 2015 (UTC)
