Tunable capillary-induced attraction between vertical cylinders
Jennifer M. Rieser, P. E. Arratia, A. G. Yodh +2
Deformation of a fluid interface caused by the presence of objects at the interface can lead to large lateral forces between the objects. We explore these fluid-mediated attractive…
Dynamical heterogeneity in soft particle suspensions under shear
K. N. Nordstrom, J. P. Gollub, D. J. Durian
We present experimental measurements of dynamical heterogeneities in a dense system of microgel spheres, sheared at different rates and at different packing fractions in a microflu…
Centrifugal compression of soft particle packings - theory and experiment
K. N. Nordstrom, E. Verneuil, W. G. Ellenbroek +3
An exact method is developed for computing the height of an elastic medium subjected to centrifugal compression, for arbitrary constitutive relation between stress and strain. Exam…
Microfluidic rheology of soft colloids above and below jamming
K. N. Nordstrom, E. Verneuil, P. E. Arratia +5
The rheology near jamming of a suspension of soft colloidal spheres is studied using a custom microfluidic rheometer that provides stress versus strain rate over many decades. We f…
Ordered clusters and dynamical states of particles in a vibrated fluid
Greg A. Voth, B. Bigger, M. R. Buckley +4
Fluid-mediated interactions between particles in a vibrating fluid lead to both long range attraction and short range repulsion. The resulting patterns include hexagonally ordered…
Mechanisms for slow strengthening in granular materials
W. Losert, J. -C. Geminard, S. Nasuno +1
Several mechanisms cause a granular material to strengthen over time at low applied stress. The strength is determined from the maximum frictional force F_max experienced by a shea…
