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…
Diffusion of single ellipsoids under quasi-2D confinements
Y. Han, A. Alsayed, M. Nobili +1
We report video-microscopy measurements of the translational and rotational Brownian motions of isolated ellipsoidal particles in quasi-two-dimensional sample cells of increasing t…
Particle dynamics in colloidal suspensions above and below the glass-liquid re-entrance transition
Andrzej Latka, Yilong Han, Ahmed M. Alsayed +3
We study colloidal particle dynamics of a model glass system using confocal and fluorescence microscopy as the sample evolves from a hard-sphere glass to a liquid with attractive i…
Geometric Frustration in Buckled Colloidal Monolayers
Yilong Han, Yair Shokef, Ahmed M. Alsayed +3
Geometric frustration arises when lattice structure prevents simultaneous minimization of local interactions. It leads to highly degenerate ground states and, subsequently, complex…
