Figure 4 shows the atom-by-atom formation of osmium molecules, clusters made up of a few Os atoms and nanocrystals. This appears to be the first observation of atom-by-atom fabrication of ...

Work with osmium compounds is endowed with peculiar personal danger to the chemist, owing to the great facility exhibited under the most various conditions for the formation of the tetroxide OsO4 ...

By constructing an aromatic hydrocarbon framework around an osmium ion, chemists have created a new class of organometallic compound. The in-plane metallo-annulenes are essentially carbon clusters ...

Crystalline osmium – the scarcest and densest platinum-group metal (PGM) globally – attracts more long-term opportunities for investors than diamonds, says precious metals refiner Gauteng ...

Osmium tetroxide is the chemical believed to be at the centre of an alleged bomb plot foiled by UK and US intelligence agents. It is thought the supposed plan involved detonating an explosive device ...
