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 …

Colloidal model systems allow studying crystallization kinetics under fairly ideal conditions,
with rather well-characterized pair interactions and minimized external influences. In …

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 …

Particle dynamics simulations are used to determine the shear-induced microstructure and
rheology of jammed suspensions of soft particles. These suspensions, known as soft particle …

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 …

The cage effect is generally invoked when discussing the delay in the decay of time
correlation functions of dense fluids. In an attempt to examine the role of caging more …

We report the results of dynamic light scattering measurements of the coherent intermediate
scattering function (ISF) of glasses of colloidal hard spheres for several volume fractions and …

We study dynamic two-body correlation functions, ie, the two-body density, the current-
density correlator, or van Hove current, and the current-current correlator in Brownian …

The conventional view of freezing holds that nuclei of the crystal phase form in the
metastable fluid through purely stochastic thermal density fluctuations. The possibility of a …

Refractive index matched particles serve as essential model systems for colloid scientists,
providing nearly hard spheres to explore structure and dynamics. The poly (methyl …
