Droplet Breakup Against an Isolated Obstacle
David J. Meer, Shivnag Sista, Mark D. Shattuck +2
We describe combined experiments and simulations of droplet breakup during flow-driven interactions with a circular obstacle in a quasi-two-dimensional microfluidic chamber. Due to…

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…
