The aim of this research is to calculate the elastic constants and Bulk modulus of Cu-20 wt% Ni random Nanoalloy. The molecular dynamics simulation technique was used to calculate the mechanical properties in NPT ensemble. The interaction between atoms as well as cohesive energy in the Nanoalloy modeled systems was calculated by Morse et al. two body potential. Also the temperature of the syste...

during estuarine mixing of fresh water with saline water and due to the flocculation process, aportion of dissolved metals come into particulate phase, and the dissolved load decreases. this process plays an important role in self-purification of heavy metals in rivers. in this study, flocculation of cu, mn, ni, pb and zn during mixing of cheshme-kileh river water with caspian sea water has bee...

Ni-Co/Cu multilayers have been grown by electrodeposition method from a single electrolyte (based on Ni(SO4).6H2O, Co(SO4).7H2O, Cu(SO4) and H3BO3) using galvanostatic control on titanium sublayers. The X-ray diffraction (XRD) patterns confirmed the multilayered structure with the nanometer thicknesses. Also, electron diffraction x-ray (EDX)  analysis confirmed the purity of deposited samples. ...

Standard enthalpies of formation of ternary phases in the Cu-Ni-Sn system were determined along sections at 25, 41 and 45.5 at.% Sn applying tin solution drop calorimetry. Generally, the interaction of Ni with Sn is much stronger than that of Cu with Sn. Along all sections the enthalpy of formation changes almost linearly with the mutual substitution of Cu and Ni within the respective homogenei...

the bioavailability of trace metals, their biological uptake and ecotoxiccological effect on soil biota can be better understood in terms of their chemical fractionation. the present study examined the mobility and availability of cd, cu, ni, pb and zn in sewage water – irrigated soils using sequential extraction technique as a basis for predicting metal uptake by plants. the residual fraction ...

heavy metal concentrations in surface water, wastewater and sediments collected from mighan lake in markazi province, iran were analyzed, and assessment contamination were evaluated according to the water and sediment quality guidelines. the results showed that the average concentrations of heavy metals in water were ranked as: ni> cr> pb> fe> cu> zn. in comparison with results the background v...

The current paper determines heavy metals in sediments of six freshwater wetlands of greater Dhaka district from November 1999 to September 2000. The sampling took place in summer, rainy season, and winter, wherein for each season five soil samples were collected from the wetland at a depth of 0 – 15 cm. To assess the status of heavy metal pollution in the sediments, geo-accumulation factor (Ig...

Miniaturization of electronic devices has led to the development of 3D IC packages which require ultra-small-scale interconnections. Such small interconnects can be completely converted into Cu-Sn based intermetallic compounds (IMCs) after reflow. In an effort to improve IMC based interconnects, an attempt is made to add Ni to Cu-Sn-based IMCs. Multilayer interconnects consisting of stacks of C...
