ruthenium

It's hard to hide things like this, see the Ruthenium plume that was detected over Europe in 2017 [0].

Tsubame is using a new ruthenium-based catalyst that lowers the reaction temperature (and therefore, also the pressure).

They convert sugars (or sugar-like compounds) into hydrocarbons by catalytic removal of oxygen with hydrogen on ruthenium.

If they are happy to get gold-plated ruthenium cables with diamond coatings, more power to them.

Most titanium has a small amount of ruthenium alloyed with it, which greatly increases corrosion resistance.

I don't think that's ruthenium -- that graph has a gap at technetium (Z=43), which has no long-lived isotopes.

Even 'platinum' mines end up producing platinum, palladium, rhodium, ruthenium, iridium and osmium rather than just platinum.

I don't know about ruthenium in particular, but almost all heavy metals are toxic to humans.

Only 6 elements (ruthenium, palladium, rhenium, iridium, and rhodium) are rarer.

Don't know why I wrote ruthenium, that is obviously a mistake.

Assuming the linked chart is accurate, it seems that ruthenium is currently about half the cost of palladium, however it has in the past been much more - up to $800 per ounce.

Alternative metals like Cobalt and Ruthenium have been proposed and to some extent used in production as an alternative to Cu for the low interconnect layers, but they just arrest the trend -- the fact is that the interconnect resistance is much higher than it used to be.

It's apparently a "metal complex of the element ruthenium".

Pretty impressive stuff: > "The researchers used cadmium–selenium dots 3nm in diameter to seamlessly replace iridium and ruthenium catalysts in five different bond forming reactions including β-alkylation and β-aminoalkylation.

Or else when Plato speaks about the grains of diamond found together with alluvial gold, that has nothing to do with what is now named diamond (which became known to the Greeks only later, after the expeditions of Alexander the Great), but "diamond" was the name for nuggets of native osmium-iridium-ruthenium alloy.

Ruthenium and Iridium are known stable catalysts that are also among the most rare elements.

The only really viable class of materials at the moment are Nickel-based single-crystal superalloys that contain rare metals like Rhenium and Ruthenium.

It would be nice if someone could explain any of the exceptions to the Oddo-Harkins rule, such as the dip at atomic number 44, Ruthenium.
