Journal ArticleDOI
Microrheological modeling of weakly aggregated dispersions
TL;DR: In this article, a microrheological model of aggregating dispersions is proposed in which the shear stress is estimated as the sum of hydrodynamic and structural parts.
Deformation of giant lipid bi-layer vesicles in a shear flow
TL;DR: A simple model has been developed that describes the deformation of a vesicle and its value has been compared with literature data and with results from micropipette aspiration experiments, which shows that the relevant mechanical parameter is the bending rigidity.
Journal ArticleDOI
Droplet breakup in concentrated emulsions
TL;DR: In this paper, the authors reported an experimental study on the conditions for droplet breakup in concentrated emulsions under simple shear flow and found that the critical shear rate for breakup decreased by more than an order of magnitude for the most concentrated emulsion.
Journal ArticleDOI
Deformation of giant lipid bilayer vesicles in shear flow
TL;DR: In this article, the deformation of giant lipid bilayer vesicles in shear flow was investigated with a counterrotating Couette apparatus. But the results showed that the relevant mechanical parameter is the bending rigidity of the vesicle.
Journal ArticleDOI
Linear Rheology of Guar Gum Solutions
TL;DR: In this article, the authors investigated the linear viscoelastic behavior of guar gum solutions as a function of frequency, temperature, polymer concentration, and molecular weight, and concluded that at least two different relaxation mechanisms must play a role, classical reptation not being one of these.
