Many high-concentration multiphase materials that are industrially and academically
important do not reach thermodynamic equilibrium because of kinetic constraints originating …

X-ray photon correlation spectroscopy (XPCS) has emerged as a powerful technique for
investigating slow, nanometer-scale structural dynamics in materials. This paper reviews …

Soft solids with tunable mechanical response are at the core of new material technologies,
but a crucial limit for applications is their progressive aging over time, which dramatically …

We study via theory and dynamical simulation the evolving structure, particle dynamics, and
time-dependent rheological properties of an aging colloidal gel, with a focus on the micro …

Understanding and controlling physical aging, that is, the spontaneous temporal evolution of
out-of-equilibrium systems, represents one of the greatest tasks in material science. Recent …

Coarsening and kinetic arrest of colloidal systems undergoing spinodal decomposition (SD)
is a conserved motif for forming hierarchical, bicontinuous structures. Although the …

The kinetics of heat-induced gelation and the microscopic dynamics of a hen egg white gel
are probed using x-ray photon correlation spectroscopy along with ultrasmall-angle x-ray …

The ageing behaviour of dense suspensions or pastes at rest is almost exclusively attributed
to structural dynamics. Here, we identify another ageing process, contact-controlled ageing …

Understanding and designing sophisticated new materials require measurements of not
only their average structural properties but also their dynamic behavior. X-ray photon …

We investigate yielding in a colloidal gel that forms a heterogeneous structure, consisting of
a two-phase bicontinuous network of colloid-rich domains of fractal clusters and colloid-poor …
