ABSTRACT
The following closely related nanostructures can be classi£ed as simple, linear 1D, 2D, and 3D nanostructures: nanolines, nanopencils, nanodumbbells, nanopins, nanoshuttles, nanopeapods, nanobricks, nanochains, nanowicks, nanobars, and nanopillars. Some of them are very rare, such as, for instance, nanopencils or nanoshuttles.
