    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]

  3. Lithium ruthenate - Wikipedia

    en.wikipedia.org/wiki/Lithium_ruthenate

    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 ...
