3-D Curved Crystal (video) University of Chicago Loading video... Caption This video shows colloidal beads (bright dots) that have assembled themselves on a liquid droplet to form a three-dimensional curved crystalline structure. The positive electric charges cause the beads to repel each other, leading them to arrange themselves naturally in a honeycomb pattern with each particle equally distant from six others.
