Microstructure of polydisperse colloidal gels
Benjamin F. Lonial, Eric R. Weeks
We use confocal microscopy to image colloidal gels formed from highly polydisperse particles. We suspend our polydisperse particles in a density matched solvent, and let the partic…

Nonaffine motion in flowing highly polydisperse granular media
Pablo Eduardo Illing, Eric R. Weeks
We study the particle-scale motion of highly polydisperse hard disks flowing in a two-dimensional bent channel. We use various size distributions of particles, in which the largest…

Aging of colloidal gels in microgravity
Swagata S. Datta, Waad Paliwal, Eric R. Weeks
We study the aging of colloidal gels using light microscopy movies of depletion gels from the International Space Station. Under such microgravity conditions, we observe a slowdown…
