We recently reviewed the experimental determination of the volume fraction, ϕ, of hard-
sphere colloids, and concluded that the absolute value of ϕ was unlikely to be known to …

Systems of spherical colloidal particles mimic the thermodynamics of atomic crystals. Control
of interparticle interactions in colloids, which has recently begun to be extensively exploited …

Phase segregation is ubiquitously observed in immiscible mixtures, such as oil and water, in
which the mixing entropy is overcome by the segregation enthalpy,–. In monodispersed …

We describe measurements of colloidal transport through arrays of micrometer-scale
potential wells created with holographic optical tweezers. Varying the orientation of the trap …

While the important role of electrostatic interactions in aqueous colloidal suspensions is
widely known and reasonably well-understood, their relevance to nonpolar suspensions …

Melting of two-dimensional colloidal crystals is studied by video microscopy. The samples
were composed of microgel spheres whose diameters could be temperature tuned, and …

We describe ion distribution and the current–voltage (i–V) response of nanopipettes at
different probe-to-substrate distances (D ps) as simulated by finite-element methods. Results …

The self-assembly of nanoparticles can enable the generation of composites with
predesigned properties, but reproducing the structural diversity of atomic and molecular …

Colloids are suspensions of small solid particles in a liquid and exhibit glassy behavior
when the particle concentration is high. In these samples, the particles are roughly …

Classic binary materials, ranging from polymer blends to table salts, contain equilibrium
phases or crystals of two interacting components. Here, we report on the construction of …
