Why do particle suspensions exhibit shear thickening behaviour?

Flow curves which I have obtained for 1% (w/v) suspensions of kaolinite clay, montmorillonite clay and silica microspheres all reveal shear thickening behaviour (an increase in viscosity) at...

What explanation(s) can be given for the frequency dependent rheological properties exhibited by clay suspensions?

Suspensions of clay particles at a concentration of 1% (w/v) were examined using frequency sweep on a rheometer and the resulting G' and G'' values were observed to be frequency dependent. That...

Is it possible to measure the intrinsic viscosity of dilute polymer solutions using a rheometer? If so, what conditions would be necessary?

Traditionally, measurement of intrinsic viscosity is performed using capillary viscometers. A rheometer can also be used to measure viscosity but I've not seen evidence of it being used in this...
