| The cells in these images were postfixed with osmium tetroxide. |
| The tissue is then placed for 8 to 10 days in a solution containing potassium chlorate, osmium tetroxide, formaldehyde, and glacial acetic acid. |
| Osmium tetroxide is used by scientists to stain materials and as a catalyst to speed up chemical reactions. |
| The oxidizer used with hypergolic fuel is usually nitrogen tetroxide or nitric acid. |
