Soft Matter and Complex Systems Seminar

Viscosity of suspension is a macroscopically measurable quantity originating in the microscopic structure of the colloid. Based on the viscosity measurements it is possible to infer about the microscopic details of the colloid like equilibrium shape of the particles suspended in the fluid. I will present a method to calculate viscosity of the solution of complex molecules modeled with spheres in Rotne-Prager-Yamakawa approximation and demonstrate it on the example of a dilute solution of dumbbells (rigid and non-rigid).
