Softness plays a key role in determining the macroscopic properties of colloidal systems,
from synthetic nanogels to biological macromolecules, from viruses to star polymers …

Amorphous solids, or glasses, are distinguished from crystalline solids by their lack of long-
range structural order. At the level of two-body structural correlations, glassformers show no …

We demonstrate that photonic media, when properly randomized to minimize the photon
transport mean free path, can be used to coat a black substrate and reduce its temperature …

Passive daytime radiative cooling (PDRC) devices have enabled subambient cooling of
terrestrial objects without any energy input, offering great potential to future clean energy …

The natural habitats of microorganisms in the human microbiome, ocean and soil
ecosystems are full of colloids and macromolecules. Such environments exhibit non …

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 simplicity of hard spheres as a model system is deceptive. Although the particles
interact solely through volume exclusion, that nevertheless suffices for a wealth of static and …

We study the melting of quasi-two-dimensional colloidal hard spheres by considering a tilted
monolayer of particles in sedimentation-diffusion equilibrium. In particular, we measure the …

In the last two decades, advances in synthetic, experimental and modeling/simulation
methodologies have considerably enhanced our understanding of colloidal suspension …

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 …
