We use x-ray photon correlation spectroscopy (XPCS) to probe the dynamics of colloidal particles in polycrystalline ice. During freezing, the dendritic ice morphology and rejection of particles from the ice created regions of high particle density, where some of the colloids were forced into contact and formed disordered aggregates. The particles in these high density regions underwent ballistic motion, with a characteristic velocity that increased with temperature. This ballistic motion is…

Real space study of pattern formation in freezing colloidal suspensions
We investigate the interaction of colloidal particles with ice-water interfaces. To this end, the experimental setup we use consists of a directional solidification stage, a light microscope, and
Segregated Ice Growth in a Suspension of Colloidal Particles.
TLDR
Surprisingly, it is found that the growth rate of a lens does not depend on its undercooling, and this is relevant for ice segregation occurring in a wide range of situations, ranging from model lab experiments and theories to geological and industrial processes, like frost heave and frozen food production.
Investigating the Freezing of Colloids: Experimental Techniques to Probe Solidification Patterns, Crystal Growth, and Particle Movement
The freezing of colloids is a complex phenomenon, with multiple, interdependent parameters. A proper observation is thus often the first step towards a better understanding. Many concomitant

TLDR
The effects of hydrodynamic interactions on the translational and rotational diffusivities of spheroidal particles of arbitrary aspect ratio in dilute monodisperse suspensions are calculated and are found to be more sensitive to eccentricity than for oblate spheroids.
Understanding the Freezing of Colloidal Suspensions: Crystal Growth and Particle Redistribution
The solidification of colloidal suspensions is ubiquitous in nature and technology. Whereas we want to control the microstructure and architectures of materials obtained through freezing routes,

TLDR
The results clearly show the important roles of surface freezing and the surface coverage of particles on the gas-liquid interface in formation of colloidal fibers.

TLDR
The basic principles of X-ray photon correlation spectroscopy are reviewed, some novel approaches to XPCS analysis are discussed, and a discussion of the future impact of diffraction-limited storage rings on new types of X PCS experiments is discussed.

TLDR
A range of settings in which the bulk and surface behaviour can interact on equal footing are discussed, including the dynamic and thermodynamic behaviour of floating sea ice, the freezing and drying of colloidal suspensions (such as soil) and the mechanisms of protoplanetesimal formation by inter-particle collisions in accretion discs.

Particle-scale structure in frozen colloidal suspensions from small-angle x-ray scattering.
TLDR
The results of experiments are presented in which the particles were concentrated into regions between ice dendrites forming a microscopic pattern of high- and low-particle-density regions, suggesting that the particle packing induced by freezing differs from that formed during equilibrium densification processes.
Dynamics of a colloid-stabilized cream.
TLDR
X-ray photon correlation spectroscopy is used to investigate the dynamics of a high-volume-fraction emulsion creaming under gravity and shows the combination of ballisticlike dynamics, an exponent that drops below 1, and large intermittent fluctuations has not been reported before to the authors' knowledge.

TLDR
The dynamic properties of nanoparticles suspended in a supercooled glass forming liquid are studied by x-ray photon correlation spectroscopy, suggesting a cooperative behavior governed by the near-vitreous solvent.
Metastable and unstable cellular solidification of colloidal suspensions.
TLDR
This work demonstrates and rationalizes the existence of instability and metastability domains in cellular solidification of colloidal suspensions, by direct in situ high-resolution X-ray radiography and tomography observations, and explains interface instabilities by a partial Brownian diffusion of the particles leading to constitutional supercooling situations.

TLDR
The theoretical stability threshold is determined experimentally, thereby demonstrating that colloidal suspensions can be treated analogously to atomic or molecular alloys.
Evolution of particle-scale dynamics in an aging clay suspension.
TLDR
The decrease in the range of this motion and an increase in suspension conductivity with increasing t(a) indicate a growth in interparticle repulsion as the mechanism for internal stress development implied by models that describe the dynamics in disordered elastic media in terms of strain from random, local structural rearrangements.

TLDR
It is proposed that the unusual ultraslow dynamics are due to the relaxation of internal stresses, built into the sample at the jamming transition, and simple scaling arguments that support this hypothesis are presented.
