Dynamics of colloidal particles in ice
Melissa Spannuth, S. G. J. Mochrie, S. S. L. Peppin +1
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…
Particle-scale structure in frozen colloidal suspensions from small angle x-ray scattering
Melissa Spannuth, S. G. J. Mochrie, S. S. L. Peppin +1
During directional solidification of the solvent in a colloidal suspension, the colloidal particles segregate from the growing solid, forming high-particle-density regions with str…
Axisymmetric viscous gravity currents flowing over a porous medium
Melissa J. Spannuth, Jerome A. Neufeld, J. S. Wettlaufer +1
We study the axisymmetric propagation of a viscous gravity current over a deep porous medium into which it also drains. A model for the propagation and drainage of the current is d…
Onsager reciprocity in premelting solids
S. S. L. Peppin, M. Spannuth, J. S. Wettlaufer
The diffusive motion of colloidal particles dispersed in a premelting solid is analyzed within the framework of irreversible thermodynamics. We determine the mass diffusion coeffic…
Stress transmission through three-dimensional granular crystals with stacking faults
Melissa J. Spannuth, Nathan W. Mueggenburg, Heinrich M. Jaeger +1
We explore the effect of stacking fault defects on the transmission of forces in three-dimensional face-centered-cubic granular crystals. An external force is applied to a small ar…
