Nano might be really small, but the consequences …

 · Nano might be really small, but the consequences might not be. If you''re really old school and print this article on a piece of paper, the paper would typically be around 100,000 nanometres thick. This is still too much to be defined as nano, however. To meet that description, most of the particles in a material need to be between 1 and 100 ...

Size Dependence of Nano-/Microparticles Flowing Through …

When the particles flowed through the matrix, no size dependence was observed. In contrast, when a fracture existed in the matrix, the larger particles were observed only at early time, while the smaller particles were detected over a wider range of time.
