As one increases the concentration of a colloidal suspension, the system exhibits a dramatic
increase in viscosity. Beyond a certain concentration, the system is said to be a colloidal …

The understanding of hydrodynamic forces around particles, drops, or bubbles moving in
Newtonian liquids is modestly mature. It is possible to obtain predictions of the attractive …

The locomotion of microorganisms and spermatozoa in complex viscoelastic fluids is of
critical importance in many biological processes such as fertilization, infection, and biofilm …

In the study of fluid dynamics and transport phenomena, key quantities of interest are often
the force and torque on objects and total rate of heat/mass transfer from them …

New developments in the microrheology of complex fluids are considered. Firstly the
requirements for a simple modern particle tracking microrheology experiment are …

Microrheology was proposed almost twenty years ago as a technique to obtain rheological
properties in soft matter from the microscopic motion of colloidal tracers used as probes …

We introduce active, probe-based microrheological techniques for measuring the flow and
deformation of complex fluids. These techniques are ideal for mechanical characterization …

We study the mechanically driven flows of non-Newtonian fluids in narrow and confined
configurations. Using the Lorentz reciprocal theorem, we derive a closed-form expression for …

Many biological fluids have polymeric microstructures and display non-Newtonian rheology.
We take advantage of such nonlinear fluid behavior and combine it with geometrical …

Langevin equations or generalized Langevin equations (GLEs) are popular models for
describing the motion of a particle in a fluid medium in an effective manner. Here we …
