Characterizing particle rearrangements in sheared highly polydisperse materials
Waad Paliwal, Eric R. Weeks
We compare three particle-scale measures of rearrangement in highly polydisperse materials under driven flow: (a) nonaffine motion defined relative to the time-averaged mean flow,…

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…
