A team from Forschungszentrum Jülich and RWTH Aachen University has developed a novel approach for a catalyst that combines ...

Iridium appears as symbol Ir on the periodic table and has an atomic weight of 192.217 and a density of 22.56 g/cm³, making it the second-densest known element.

Iridium is a very hard, brittle and dense metal and is also very rare. (Image credit: Images of Elements) Iridium is the most corrosion-resistant element on the Periodic Table of Elements.

Scientists have taken a major step toward solving one of the biggest challenges facing green hydrogen: the scarcity of ...

Like gold, iridium is pretty unreactive and has a very high density and melting point. In fact, iridium is the most corrosion-resistant element within the Periodic Table.

Iridium, named after a chemical element, provides voice and data transmissions from anywhere on Earth, courtesy of a constellation or network of 66 active, interconnected low-altitude satellites.

Iridium Dressed To The Nines Periodic Table: IrO 4+ is the first molecule with an element in the +9 oxidation state by Stephen K. Ritter October 23, 2014 3 min read ...

However, iridium is one of the rarest elements on earth, and one of the major challenges is to significantly reduce the demand for this precious metal.

Iridium is rare in the Earth’s crust because it is a siderophile, which means that it dissolves in iron and therefore tends to sink into the Earth’s core. Iridium is much more abundant in asteroids, ...

Iridium-192 is a radioactive isotope, meaning it's a version of iridium with a different number of neutrons than is contained in the dominant forms of the element.

However, the characteristic ratios of HSEs in the Earth’s upper mantle (for example the ruthenium/iridium element ratio of about 2) match up with theoretical predictions for asteroids formed in ...
