It is ascertained that, in conjoined presence of Re(VII) and Mo(VI) ions in neutral and alkaline media (at pH 5-14), rhenium
can be separated from molybdenum with use of the copolymers.
However, since technetium and rhenium
belong to the same group 7 of the transition series, the similarities between [sup.99m]Tc and [sup.188]Re radiopharmaceuticals are even more pronounced.
's uniqueness is its high melting point (3,180 C)and high density (21.04 g/cc).
A special feature of the structure of the subsurface layer of the truth of the tailpiece was that as a result of diffusion interaction of the components of the alloy with carbon of the cooling medium the matrix solution (at a depth of up to 30 [micro]m) was depleted in alloying elements tungsten (from 12.7 to 9.67%) and rhenium
(from 3.67 to 1.84%), which diffused to the surface and took part in the formation of carbides.
Ivanhoe Mines (TSX: IVN)(NYSE: IVN)(NASDAQ: IVN), a Canada-based mining company with gold and copper mining properties in Mongolia, has announced discovery of high grade molybdenum and rhenium
at the Merlin Project in North Western Queensland, Australia.
Separation of osmium by distillation and separation of rhenium
by extraction were performed based on the analytical method from Du et al.
With one to 25 pins per site, the probe includes a standard 0.0125 mm diameter polished round tungsten rhenium
probe tip (other tips available).
On the day before surgery, each patient received an intracervical injection of 120 MBq of colloidal rhenium
sulfur labeled with technetium-99m; this was followed 12 hours later with lymphoscintigraphy.
There has also been a considerable growth in the study of one of such rare transition metals "Rhenium
Magnesium-based alloys, MMC (metal matrix composites), intermetallic materials and alloys containing more than 5% of beryllium, iridium and rhenium
has designed a new generation of portable X-ray Florescence Analyzers delivering fast, precise identification and analysis of the most challenging metal alloys, including stainless steel, nickel/cobalt superalloys, specialty molybdenum, rhenium
, tungsten alloys, and precious metals.
Rolls-Royce Plc, an aero engine manufacturer, has indicated that it will be using Rhenium
, a rare naturally-occurring element, in its future Trent aircraft engines, including the Trent 900, which is designed for the Airbus A380 superjumbo jet aircraft.
