The composition dependence of the emission intensities was investigated in Cu-Ni as well as Ni-Zn binary alloy samples when a low-pressure argon laser-induced plasma was employed as the excitation source. The calibration curve in the Cu-Ni alloy system gave a linear relationship, implying that the selective evaporation of Cu or Ni atoms was caused less in those alloys having several chemical co...

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...

levels of the heavy metals copper (cu), zinc (zn), lead (pb), cadmium (cd), chromium (cr), nickel (ni), iron (fe) and manganese (mn) were determined by graphite furnace atomic absorption spectrophotometer (model 67og) in coastal water, sediments and soft tissues of the saccostrea cucullata, from the intertidal zone at five stations in the gulf of chabahar on the iranian coasts along the oman se...

Scanning tunneling microscopy studies of Ni islands deposited on TiO2(1 1 0) show that the islands grow threedimensionally at room temperature with an average height of approximately 6.5 A and diameter of 30 A. The broadness of the island size distributions can be controlled by the diffusion (D) to deposition flux (F ) ratio, with the narrowest distribution corresponding to the smallest D=F rat...

in this research a layer of ni-cu-p was deposited on 304 stainless steels by using gelatin and thiourea asadditives in a sulfate solution. in order to determine the properties of deposited layers, a microhardness testerwas used for microhardness measurement, x.r.d. for microstructural analysis, and a scanning electronmicroscope equipped with e.d.x. for determining morphology and analyzing the d...

The microstructure of sputter deposited Ti-rich Ni-Ti thin films doped with Cu in the range 020.4 at.% and annealed for 1 h at 500 and 600°C has been investigated and correlated with the mechanical properties of the films measured by depth-sensing nanoindentation. X-ray diffraction analysis showed the microstructural evolution of Ni-Ti thin films when doped with Cu and annealed at different tem...
