I fail to see how there are phase transitions in vehicle suspensions, let alone entropy changes.

Good thread to confuse most of the people on here though! LOL

generally speaking, I think we're talking about molecular migration between different (presumably in liquid state) phases due differences on physical and chemical properties, like polarity and water affinity.... hmmm... those old days....

Indeed.

I have found that the phase behavior of model athermal silica–polystyrene–toluene suspensions has been determined over nearly two orders of magnitude in polymer or colloid size asymmetry.

Yeah, but don't forget that predictions of fluid-fluid spinodal phase separation by the microscopic polymer reference interaction site model integral equation theory of athermal polymer-colloid suspensions are in agreement with the experimental observations.

Precisely, sir. Polymer–polymer interactions, chain fractal structure, and structural reorganizations are implicated as critical physical factors.

it would be really interesting to see how the substract molecules in a solution like the one you're mentioning (silica–polystyrene–toluene suspensions) would react to the application of a difference of potential, let's say 3.7V....

All I can contribute to this discussion is a picture of a monkey having a smoke.

Attractive interactions between droplets may induce reversible phase transitions or flocculation and depending upon the densities of the solvent and the droplets, sedimentation or creaming occurs.

Google is so funny...

Here's one from our patent guys that would actually be useful in RC:

"Field-controllable, semi-active magneto-rheological fluid (MRF) shock absorbers" Enjoy the Google.
