Light guiding and manipulation in photonics have become ubiquitous in events ranging from
everyday communications to complex robotics and nanomedicine. The speed and sensitivity …

Inorganic nanocrystal gels retain distinct properties of individual nanocrystals while offering
tunable, network-structure-dependent characteristics. We review different mechanisms for …

This review collects and describes experiments that employ colloidal suspensions to probe
physics in ordered and disordered solids and related complex fluids. The unifying feature of …

Spherical colloidal particles generally self-assemble into hexagonal lattices in two
dimensions. However, more complex, non-hexagonal phases have been predicted …

The use of dynamically bonded molecules designed to reversibly link solvent-dispersed
nanocrystals (NCs) is a promising strategy to form colloidal assemblies with controlled …

Low-density “equilibrium” gels that consist of a percolated, kinetically arrested network of
colloidal particles and are resilient to aging can be fabricated by restricting the number of …

Restricting the number of attractive physical “bonds” that can form between particles in a
fluid suppresses the usual demixing phase transition to very low particle concentrations …

Colloidal particles are normally considered to be topographically smooth and chemically
uniform (down to the nanoscale). Nevertheless, surface heterogeneities do exist and have a …

Gelation of colloidal nanocrystals emerged as a strategy to preserve inherent nanoscale
properties in multiscale architectures. However, available gelation methods to directly form …

The entropic depletion interaction has been the subject of several studies over the past
decade because it plays an important role in many industrial applications and also involves …
