Nickel–cobalt alloys were prepared by alloy electrodeposition with a sulfamate bath, and the mechanical properties on micro-scale evaluated for application as micro-components in miniaturized electronic devices. Nickel bromide commercially available surface brightener used additives. The cobalt content increased from 21.5 to 60.1 at.% after addition of nickel into grain size refined 21.1 13.2 n...

Nickel films of 300 nm thickness were deposited by electron beam evaporation at room temperature on 316 stainless steels. Corrosion studies of Ni coated 316 SS have been performed after N+ ion implantation at different energies of 20, 40, 60 and 80 keV. The structure and surface morphology of the films were evaluated using X-ray diffraction (XRD), atomic force microscope (AFM) an...

Among the various molecular interactions used to construct supramolecular self-assembling systems, homoliganded metallic NTA-Ni-NTA complexes have received little attention despite their considerable potential applications, such as the connection of different biochemical functions. The stability of this complex is investigated here by using two concordant nanotechniques (surface forces apparatu...

Due to its pseudo elastic behavior, the nickel-titanium (nitinol) alloy has been used in the manufacture of endodontic instruments in recent years, being especially useful for curved canals preparation. Extensive research has been carried out to improve the wear resistance of the nitinol instruments without create modifications in the bulk of the files. The purpose of this work was to measure t...

As plating proceeds, both nickel and hypophosphite ions are consumed. These deficiencies can be corrected by adding nickel and hypophosphite salts. However, as the byproduct phosphite accumulates, the quality of the deposit deteriorates. At some point the bath must be discarded and replaced-a practice that is expensive due to the cost of purchasing a new solution and disposing of the old one. T...

Background: Nickel is an important constituents widely used in different industrial processes for production of various synthetic materials. For evaluation of workers’ exposure to trace toxic metal of Ni (II), environmental and biological monitoring are essential processes, in which, preparation of samples is one of the most time-consuming and error-prone aspects prior to analysis. Methods: To ...

BACKGROUND Metal contamination is widespread and results from natural geogenic and constantly increasing anthropogenic sources (mainly mining and extraction activities, electroplating, battery and steel manufacturing or metal finishing). Consequently, there is a growing need for methods to detoxify polluted ecosystems. Industrial wastewater, surface water and ground water need to be decontamina...
