rheology studies

Overview

Rheology investigates the behavior of non-Newtonian liquids.  These fluids are mainly characterized by a non-linear relation between shear stress and shear rate.  One of the most important biological fluids belonging to this category is the blood, where its rheological properties can be attributed to the significant presence of red blood cells.  Red blood cells and their interactions with several proteins are the main reason of the visco-elastic properties of the blood, particularly at very low flow rates or in small capillaries.  Other examples include colloidal solutions, gel matrices, emulsions, polymers, where the primary interests is deepening the knowledge of shear thinning, shear thickening, yield stress and visco-elastic effects with potential innovations in food chemistry, polymer chemistry, cosmetics, filtration, material transport.
