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…
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…
