| They created a polymer whose external structure is 100 micrometres-high pillars, topped by a thin 40 micrometres wide discs, upon which tiny mushroom-shapes sit. |
| They used a microchip etching process to bore channels just 20 micrometres wide. |
| Typically, the in-plane resolution is several hundreds of micrometres with observed slices of several millimetres thickness. |
| On a weight basis, a billion ultra-fine particles are about equivalent to one coarse particle 10 micrometres in diameter, but have one thousand times the surface area. |
| These microscopic organisms, typically 1-5 micrometres long, are distinguished by the absence of sub-cellular organelles, such as a nucleus, mitochondria, and chloroplasts. |
| Pore length was measured as the length of the stomatal pore in micrometres. |
