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.
Rhenium'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.
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 are forbidden.
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.
