Nanotubes The single wall is created when a single molecular layer of graphite is rolled to form a tube structure. Also, multilayer nanotubes that form a coaxial assembly of the single layer tubes inside one another. Basically they are one-dimensional objects with a well-defined direction along the nanotube axis that is analogous to the in-plane directions of graphite. Bucky Balls A truncated icosahedron, the most round symmetrical object created by man. They are purely carbon based and can withstand tremendous amounts of force. A bucky ball launched at 24,000km/h and was slammed into a steel plate and merely bounced back with ablsolutly no change. These molecular creations all have a strenth per weight that is of 10 to 100 times greater than steel or almost any man-made alloy we have. What are some uses for these structures?
