Information @ a Glance

Contents on the CD Rom

• Osmium is a chemical element that has the symbol Os and atomic number 76.
• Osmium is a hard, brittle, blue-gray or blue-black transition metal in the platinum family.
• Osmium is found in nature as an alloy in platinum ore.
• Osmium is generally considered to be the densest known element, narrowly defeating iridium.
• Osmium is uneffected by water and acids, but dissolves with molten alkalis.
• Osmium is unworkable as a metal.
• It is proposed that 3400 ± 50 K is probably closer to the melting point of pure osmium than the value of 3300 K for impure metal
• Osmium is obtained when platinum metal is extracted from its ores.
• For osmium analyses, platinum filaments are required. Because platinum very often contains considerable amounts of osmium, rhenium and tungsten, it is essential to use ultra pure platinum material.
• Osmium catalysed aminohydroxylation of (E)-stilbene 1 with chloramine-T yielded varying amounts of an amino ketone.
• The majority of osmium is produced either as osmium tetroxide or metallic osmium.
• Various methods have been developed for recovering osmium from waste. The two major sources of osmium waste reprocessed in-house include catalysts (OsO4) and fixative solutions (OsO4) used in electron microscopy or for tissue staining.
• The major use of Osmium tetroxide material is for histological examination of tissue specimens.
• A substantial fraction of the osmium consumed by the chemical industry is apparently used for research purposes.
• Osmium, or its alloys, is still used for pivots, bearings, phonograph needles, and engraving tools because of its hardness.
• Osmium, used primarily in pen nibs and armor-piercing weapon shells.
• Osmium isotopes in seawater sediment can be used to reveal ancient meteorite strikes.
  Dendritic cells have been extensively found using zinc-iodide-osmium (ZIO) in lymphoid organs.
• Osmium-catalyzed asymmetric dihydroxylation (AD) of olefins is one of the most reliable methods for the preparation of chiral vicinal diols, which act as intermediaries in the syntheses of many biologically active substances.
• The hypothesis of the significance of the black precipitate formed in osmium preparations can be tested using Osmium techniques.
• A new technique, fixing with high levels of glutaraldehyde,replacing osmium with tannic acid followed by other heavy metals and p-phenylenediamine, and embedding in Epon.
• A newly acquired mass spectrometer MI 1201 by the Mass Spectrometry Laboratory will be adapted to determine rhenium and osmium isotope concentrations using negative thermal ionization mass spectrometry (NTIMS).
• The researchers observed from X-ray diffraction patterns how much the volume of osmium's hexagonal atomic structure shrunk with pressure.
• Osmium has only limited use in relatively expensive end-products because of its high cost, fluctuating price, and short supply.
• Existing markets for osmium metal are very competitive; consequently, suppliers and dealers are reluctant to disclose information on either uses
  or consumers.
