Elasticity-Dependent Self-assembly of Micro-Templated Chromonic Liquid Crystal Films
Matthew A. Lohr, Marcello Cavallaro, Daniel A. Beller +4
We explore micropatterned director structures of aqueous lyotropic chromonic liquid crystal (LCLC) films created on square lattice cylindrical-micropost substrates. The structures…
Effects of Particle Shape on Growth Dynamics at Edges of Evaporating Colloidal Drops
Peter J. Yunker, Matthew A. Lohr, Tim Still +3
We study the influence of particle shape on growth processes at the edges of evaporating drops. Aqueous suspensions of colloidal particles evaporate on glass slides, and convective…
Starting to move through a granular medium
D. J. Costantino, T. J. Scheidemantel, M. B. Stone +5
We explore the process of initiating motion through a granular medium by measuring the force required to push a flat circular plate upward from underneath the medium. In contrast t…
Helical Packings and Phase Transformations of Soft Spheres in Cylinders
Matthew A. Lohr, Ahmed M. Alsayed, Bryan G. Chen +3
The phase behavior of helical packings of thermoresponsive microspheres inside glass capillaries is studied as a function of volume fraction. Stable packings with long-range orient…
Flux through a hole from a shaken granular medium
K. Chen, M. B. Stone, R. Barry +7
We have measured the flux of grains from a hole in the bottom of a shaken container of grains. We find that the peak velocity of the vibration, vmax, controls the flux, i.e., the f…
