Ruthenium red, [ (NH 3) 5 Ru-O-Ru (NH 3) 4 -O-Ru (NH 3) 5] 6+, is a biological stain used to stain polyanionic molecules such as pectin and nucleic acids for light microscopy and electron microscopy. [64] The beta-decaying isotope 106 of ruthenium is used in radiotherapy of eye tumors, mainly malignant melanomas of the uvea. [65]
Lithium ruthenate, Li 2 RuO 3, is a chemical compound of lithium, ruthenium and oxygen. It has a layered honeycomb crystal structure, and can be prepared by direct calcination of Ru metal and lithium carbonate at ca. 700 °C. [2] It is a potential lithium-ion battery electrode material, [2] though this application is hindered by the high costs ...
40.104 MJ/kg (11,140 Wh/kg) theoretical. Energy density. J / m³. Specific power. 11,400 W / kg. Nominal cell voltage. 2.91 V. The lithium–air battery (Li–air) is a metal–air electrochemical cell or battery chemistry that uses oxidation of lithium at the anode and reduction of oxygen at the cathode to induce a current flow.
Rubidium. body-centered cubic (bcc) (cI2) Rubidium is a chemical element; it has symbol Rb and atomic number 37. It is a very soft, whitish-grey solid in the alkali metal group, similar to potassium and caesium. [8] Rubidium is the first alkali metal in the group to have a density higher than water.
Rhodium is a chemical element; it has symbol Rh and atomic number 45. It is a very rare, silvery-white, hard, corrosion-resistant transition metal. It is a noble metal and a member of the platinum group. It has only one naturally occurring isotope, which is 103 Rh. Naturally occurring rhodium is usually found as a free metal or as an alloy with ...
Group 7, numbered by IUPAC nomenclature, is a group of elements in the periodic table. It contains manganese (Mn), technetium (Tc), rhenium (Re) and bohrium (Bh). This group lies in the d-block of the periodic table, and are hence transition metals. This group is sometimes called the manganese group or manganese family after its lightest member ...
primordial element. synthetic element. Group 8 is a group (column) of chemical elements in the periodic table. It consists of iron (Fe), ruthenium (Ru), osmium (Os) and hassium (Hs). [1] ". Group 8" is the modern standard designation for this group, adopted by the IUPAC in 1990. [1] It should not be confused with "group VIIIA" in the CAS system ...
Ruthenium compounds are compounds containing the element ruthenium (Ru). Ruthenium compounds can have oxidation states ranging from 0 to +8, and −2. The properties of ruthenium and osmium compounds are often similar. The +2, +3, and +4 states are the most common. The most prevalent precursor is ruthenium trichloride, a red solid that is ...
