On the left is a TEM image of the first nanospring our group produced. It is amorphous boron carbide (Nanosprings, Applied Physics Letters 79, 1540 (2001)) and the TEM image on the right is that of a silicon carbide nanospring we produced, which validated our contact angle anisotropy (CAA) model of amorphous nanospring formation (Silicon Carbide Nanosprings, Nano Letters 3, 983 (2003)).


Here is an example of a 500 um (0.5 mm) thick mat of nanosprings.
