Water and sediment samples have been collected from five different stations, located along Djendjen River between February and June, 2016 so that the concentrations of Cd, Ni, Zn, and Cu could be determined. The extent of the sediment pollution has been assessed, using the multiple pollution indices, namely Contamination Factor (CF), Pollution Load Index (PLI), and the geoaccumulation index (Ig...

The inexpensive geochemical exploration technique based on broadspaced deflation lag sampling played a key role in the discovery of the Babel and Nebo ortho-magmatic Ni–Cu–platinum group elements (PGE) deposits. An area of 1100 km in the western Musgrave Block in central Australia was explored using deflation lag samples collected on a 1 km 0.5 km grid. A total of 35 elements were determined us...

The electronic structure of BaFe2As2 doped with Co, Ni, and Cu has been studied by a variety of experimental and theoretical methods, but a clear picture of the dopant 3d states has not yet emerged. Herein we provide experimental evidence of the distribution of Co, Ni, and Cu 3d states in the valence band. We conclude that the Co and Ni 3d states provide additional free carriers to the Fermi le...

In the present study, Nickel-Copper nanoparticles were electrodeposited on glassy carbon electrode (GCE) by using electroplating deposition method. The prepared electrode was characterized by scanning electron microscopy (SEM) and elemental mapping analysis. Results showed that Ni-Cu nanoparticles with a high density are distributed at the surface of the glassy carbon electrode. Subsequentl...

Štúdium viazania stopových prvkov v sedimente vodnej nádrže Ružín Pre účely posúdenia možnosti využitia fyzikálnych a fyzikálno-chemických metód separácie, vybraná vzorka sedimentu z Ružína bola podrobené 5-stupňovej procedúre sekvenčnej extrakcie (SE) podľa Tessiera (Tessier et al., 1979) a Horowitza (Horowitz, 1991). Vo výluhoch bolo stanovované zastúpenie konštitučných (Fe, Mn, Ca a Mg) ako ...

Effects of duration of exposure of single metal cations (Ag+1, Cd+2, Cu+2, Ga+3, Ni+2, and Zn+2) on 3H-thymidine (3H-Tdr) incorporation and 3-[4,5-dimethyl-thiazol-2yl-]-2,5-diphenyl tetrazolium bromide-formazan (MTT-f) production in cultured murine fibroblasts (Balb/c 3T3) were investigated, and the synergistic and antagonistic effects of two metal cations applied simultaneously to the fibrobl...

The ability of water hyacinth ( Eichhornia crassipes Mart. Solms.) to absorb and translocate cadmium (Cd), lead (Pb), copper (Cu), zinc (Zn), and nickel (Ni) was studied in the Erh-Chung wetlands. Translocation ability was defined as the quantity of Cu, Pb, Cd, Ni, and Zn translocated in the plant’s tissues, and was expressed as a root/shoot ratio. The ratio results were in the order of Cu>Pb>C...
