Packing problems are ubiquitous,, ranging from oil extraction through porous rocks to grain
storage in silos and the compaction of pharmaceutical powders into tablets. At a given …

Over the past decade, new theoretical and experimental techniques have greatly advanced
our understanding of the transition between liquid and crystalline phases. Theoretical …

Glasses and gels are the two dynamically arrested, disordered states of matter. Despite their
importance, their similarities and differences remain elusive, especially at high density …

Confocal microscopy was used to directly observe three-dimensional dynamics of particles
in colloidal supercooled fluids and colloidal glasses. The fastest particles moved …

The mechanisms of atomic transport in supercooled liquids and the nature of the glass
transition are long-standing problems,,,. Collective atomic motion is thought to play an …

The transition of a fluid to a rigid glass on cooling is a common route of transformation from
liquid to solid that embodies the most poorly understood features of both phases,,. From the …

Sub-micrometre charged latex spheres can be suspended in water to form regular arrays
known as colloidal crystals. In contrast to most conventional solids, colloidal crystals can be …

Abstract Characterization of the microscopic fluctuations in systems that are far from
equilibrium is crucial for understanding the macroscopic response. One approach is to use …

Colloidal suspensions are widely used to study processes such as melting, freezing,, and
glass transitions,. This is because they display the same phase behaviour as atoms or …

Liquid silica is the archetypal glass former, and compounds based on silica are ubiquitous
as natural and man-made amorphous materials. Liquid silica is also the extreme case of a …
