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 …

A link between structural ordering and slow dynamics has recently attracted much attention
from the context of the origin of glassy slow dynamics. Candidates for such structural order …

We present a fast, high-throughput method for characterizing the motility of microorganisms
in three dimensions based on standard imaging microscopy. Instead of tracking individual …

We use confocal microscopy to directly observe 3D translational and rotational diffusion of
tetrahedral clusters, which serve as tracers in colloidal supercooled fluids. We find that as …

We attempt to elucidate the dynamics of multiarm star polymer solutions, which are
representative of a large class of soft hairy colloids, over a wide range of concentrations. In …

We study the emergence of a yield stress in dense suspensions of non-Brownian particles
by combining local velocity and concentration measurements using magnetic resonance …

Models, theories, and simulations for the low shear viscosity of Brownian, hard-sphere
dispersions are examined and evaluated against literature data. Hydrodynamic and …

We study concentrated binary colloidal suspensions, a model system which has a glass
transition as the volume fraction ϕ of particles is increased. We use confocal microscopy to …

The dynamics of supercooled ortho-terphenyl has been studied using photon-correlation
spectroscopy (PCS) in the depolarized scattering geometry. The obtained relaxation curves …

It is widely believed that crystallization in three dimensions is primarily controlled by
positional ordering, and not by bond orientational ordering. In other words, bond …
