| The cone shaped tip is just under one micrometer in length and has a radius of a few nanometers at its apex. |
| Nanowires are crystals only a few nanometers in diameter but up to several microns in length. |
| For comparison, the gate length of the smallest silicon transistors is about 20 nanometers. |
| Raty and his colleagues calculated that quantum confinement doesn't exist in nanodiamonds, even down to sizes as small as two nanometers across. |
| This figure was used to convert subsequent contour measurements from nanometers to kilobases. |
| The mineral forms within a protein matrix as fibrous structures about 50 nanometers wide and 500 nanometers long. |
