Life in the coffee-ring: how evaporation-driven density gradients dictate the outcome of inter-bacterial competition
David Yanni, Arben Kalziqi, Jacob Thomas +5
When a drop dries, it often leaves a ring-shaped stain through a ubiquitous phenomenon known as the coffee-ring effect. This also occurs when the liquid contains suspended microbes…
Decoupling of translational and rotational diffusion in quasi-2D colloidal fluids
Skanda Vivek, Eric R. Weeks
We observe the translational and rotational diffusion of dimer tracer particles in quasi-2D colloidal samples. The dimers are in dense samples of two different sizes of spherical c…
Long Wavelength Fluctuations and the Glass Transition in 2D and 3D
Skanda Vivek, Colm P. Kelleher, Paul M. Chaikin +1
Phase transitions significantly differ between two-dimensional and three-dimensional systems, but the influence of dimensionality on the glass transition is unresolved. We use micr…
Soap films as two-dimensional fluids: Diffusion and flow fields
Skanda Vivek, Eric R. Weeks
We observe tracer particles diffusing in soap films to measure the two-dimensional (2D) viscous properties of the films. We make soap films with a variety of water-glycerol mixture…
Temporal and spatial heterogeneity in aging colloids: a mesoscopic model
Nikolaj Becker, Paolo Sibani, Stefan Boettcher +1
A coarse-grained model of dense hard sphere colloids building on simple notions of particle mobility and spatial coherence is presented and shown to reproduce results of experiment…
