Effects of cobalt chloride, nickel chloride, and nickel subsulfide upon erythropoiesis in rats.
The erythropoietic effects of sustained intraperitoneal (i.p.) administration of CoCl2 and NiCl2 were compared with the effects of a single intrarenal (i.r.) injection of alpha Ni3S2 in female Fischer-344 rats. Infusion of NiCl2 by osmotic minipumps (0.85 mg Ni per day, i.p., for 24 days; total dose = 20 mg Ni per rat) did not alter the blood hematocrit or reticulocyte count during six weeks of...
متن کاملElectronically unsaturated three-coordinate chloride and methyl complexes of iron, cobalt, and nickel.
Three-coordinate organometallic complexes are rare, especially with the prototypical methyl ligand. Using a hindered, rigid bidentate ligand (L), it is possible to create 12-electron methyliron(II) and 13-electron methylcobalt(II) complexes. These complexes are thermally stable, and (1)H NMR spectra suggest that the low coordination number is maintained in solution. Attempts to create the 14-el...
متن کاملMagnetic Susceptibility: Solutions, Emulsions, and Cells
Differences in magnetic susceptibility between various compartments in heterogeneous samples can introduce unanticipated complications to NMR spectra. On the other hand, an understanding of these effects at the level of the underlying physical principles has led to the development of several experimental techniques that provide data on cellular function that are unique to NMR spectroscopy. To i...

15 صفحه اولNickel and Cobalt Ores: Flotation
Most of the world’s nickel is extracted from the mineral pentlandite, (Ni, Fe)9S8, which frequently occurs in ores containing predominantly pyrrhotite and various non-sulRdes, some of which contain magnesium (Table 1). The nickel content in such sulRde ores is generally low (0.2}3%) and varies from place to place in the same deposit. The low nickel content of the present-day nickel sulRde ores ...
