Using Hierarchical Self-Assembly To Form Three-Dimensional ...

Lattices of Spheres ... The beads in adjacent rods are caused to connect with one another, and either the beads or the polymer is removed from the assembled structure (Figure 1). The polymer matrix is important in the process: it supports the beads so that the self-assembled structures are stable and

SPHERE PACKING STUDIES - Grunch Net

All of the packings described above are equivalent to the face-centered cubic. Connecting the centers of adjacent spheres with rods, and allowing the spheres to fade from view, is what gives us the isotropic vector matrix in synergetics.

Circle packing - Wikipedia

Generalisations can be made to higher dimensions – this is called sphere packing, which usually deals only with identical spheres. While the circle has a relatively low maximum packing density of 0.9069 on the Euclidean plane, it does not have the lowest possible.
