Comparative carcinogenic effects of nickel subsulfide, nickel oxide, or nickel sulfate hexahydrate chronic exposures in the lung.
The relative toxicity and carcinogenicity of nickel sulfate hexahydrate (NiSO4.6H2O), nickel subsulfide (Ni3S2), and nickel oxide (NiO) were studied in F344/N rats and B6C3F1 mice after inhalation exposure for 6 h/day, 5 days/week for 2 years. Nickel subsulfide (0.15 and 1 mg/m3) and nickel oxide (1.25 and 2.5 mg/m3) caused an exposure-related increased incidence of alveolar/bronchiolar neoplas...
متن کاملTemperature Dependence Studies of 3 CI NQR Frequencies in Magnesium and Nickel Hexachlorotellurate(IV) Hexahydrates and Nickel Hexachloroiridate(IV) Hexahydrate*
The C1 NQR frequencies in MgTeCl6 • 6 H 2 0 , NiTeCl6 • 6 H 2 0 , and NiIrCl6 • 6 H 2 0 have been determined at various temperatures. These compounds form rhombohedral crystals with the space group R3, showing a single resonance line. The C1 NQR frequencies of the Te(IV) complexes exhibit an unusual positive temperature coefficient. The deuterated analogs of the Te(IV) complexes show a small fr...
متن کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Growth, corrosion, and wear study of nanocomposite PEO coating in electrolyte containing nickel sulfate
Plasma electrolytic oxidation (PEO) was performed on a 1010 Aluminum alloy. To achieve thenanocomposite structure, Si3N4 nanoparticles were added into the electrolyte. In an alkaline aqueoussuspension (silicate-based), the effect of adding NiSO4 on the applied voltage, microstructure,composition, wear, and corrosion resistance of PEO coatings was investigated using ScanningElectron Microscopy (...
متن کاملsynthesis and characterization of some macrocyclic schiff bases
ماکروسیکلهای شیف باز از اهمیت زیادی در شیمی آلی و دارویی برخوردار می باشند. این ماکروسیکلها با دارابودن گروه های مناسب در مکانهای مناسب می توانند فلزاتی مثل مس، نیکل و ... را در حفره های خود به دام انداخته، کمپلکسهای پایدار تولید نمایند. در این پایان نامه ابتدا یک دی آلدئید آروماتیک از گلیسیرین تهیه می شود و در مرحله بعدی واکنش با دی آمینهای آروماتیک و یا آلیفاتیک در رقتهای بسیار زیاد منجر به ت...
