The plurality of nanostructures may be provided such that their long axes are substantially aligned and, in some cases, continuous from end to end of the sample. For example, in some cases, the nanostructures may be fabricated by uniformly growing the nanostructures on the surface of a substrate, such that the long axes are aligned and non-parallel to the substrate surface. The nanostructures may be, in some instances, substantially perpendicular to the substrate surface. In one set of embodiments, a force with a component normal to the long axes of the nanostructures may be applied to the substantially aligned nanostructures. The application of a force may result in a material comprising a relatively high volume fraction or mass density of nanostructures.
