Osmium in a sentence

In 2011, osmium(VI) citation and osmium(II) citation compounds were reported to show anticancer activity in vivo, it indicated a promising future for using osmium compounds as anticancer drugs. citation Image:OsStaining.

After it is dissolved, osmium is separated from the other platinum group metals by distillation or extraction with organic solvents of the volatile osmium tetroxide. citation The first method is similar to the procedure used by Tennant and Wollaston.

Because osmium atoms are extremely electron-dense, osmium staining greatly enhances image contrast in transmission electron microscopy (TEM) studies of biological materials.

Blackening reveals oxidation due to irradiation by oxygen atoms. citation citation Precautions Finely divided metallic osmium is pyrophoric and reacts with oxygen at room temperature, forming volatile osmium tetroxide.

In 2012, the estimated US production of osmium was 75 kg. citation Applications Because of the volatility and extreme toxicity of its oxide, osmium is rarely used in its pure state, but is instead often alloyed with other metals.

Osmium pentafluoride (OsF 5 ) is known, but osmium trifluoride (OsF 3 ) has not yet been synthesized.

Osmium powder has the characteristic smell of osmium tetroxide.

Since hassium is homologous to osmium, it should also occur along with osmium in osmiridium if it occurred in nature.

Smithson Tennant born Selby, educated in Beverley, discovered osmium and iridium in 1803; the two are atomic numbers 76 and 77, with osmium being the densest naturally occurring element, and iridium is the next densest.

The Drone Station costs one osmium rod, one fusion cell, one super alloy rod, and three circuit boards, a material that was also added with the Fish and Drones update.

Now Jaime Maussan claims that these “alien corpses” have what he believes to be communication devices that were made in part with a rare metal known as osmium embedded in their bodies.

Its PGM deposits include platinum, palladium, rhodium, iridium, ruthenium, and osmium.

In this case, the osmium compound JPC11, with sodium formate, can selectively produce a molecule of a specific “handedness” — thus manipulating how cancer cells grow.

By contrast, osmium dioxide (OsO 2 ) is black, non-volatile, and much less reactive and toxic.

Chemical properties seeAlso Osmium forms compounds with oxidation states ranging from −2 to +8.

Chemistry experiments have confirmed that hassium behaves as the heavier homologue to osmium in group 8. The chemical properties of hassium are characterized only partly, but they compare well with the chemistry of the other group 8 elements.

For instance, osmium -iridium alloys could be investigated if platinum's propensity to absorb hydrogen (due to catalysis of VOCs and hydrocarbon-based cleaning solvents) and atmospheric mercury proved to be sources of instability.

In " That Which Survives ", the alloy of diburnium and osmium is stated to be the hardest alloy known to the Federation.

Like iron but unlike osmium, ruthenium can form aqueous cations in its lower oxidation states of +2 and +3.

Like osmium tetroxide, ruthenium tetroxide is a potent fixative and stain for electron microscopy of organic materials, and is mostly used to reveal the structure of polymer samples.
