"Self-assembly of 5 micrometer glass nanospheres on a mica surface. The spheres are initially suspended in a drop of
water on the mica. As the drop evaporates, the spheres are packed together by the surface tension at the drop's edge.
Slight irregularities in the packing can be seen, and are the result of irregularly shaped spheres. (300K) Movie by
"Triangles, made of polydimethylsiloxane with magnetized strontium ferrite along the edges, self assemble on the
surface of water. The different color triangles are oppositely magnetized so they are expected to have the strongest
attractions. The dish and camera are moved circularly to produce a wave that moves the pieces. The movie plays in
real time." Movie by G.C. Lisensky

Virtual Lab: Atomic Crystal Growth using Molecular Beam Epitaxy:
Virtual Lab Simulations of "Quantum Cellular Automata" Electronic Device Building Blocks:
Square array of Q-dots with affinity for electrons. The dots are so small & close (~30 nm) that charges repel one another. Net result is that cell charges up with only two electrons that run to opposite corners of the cell.
The result it two alternate charging patterns => Digital 1 and 0!
Which can be manipulated by input signals on a pair of wires.
Further, the charge arrangement of the first cell will then propagate along a “wire” of such QCA elements!
