The Ni(II) and Zn(II) complexes with phenylpyridylformamidine (PhPyF) ligand, [Ni(PhPyF)Cl2] and [Zn(PhPyF)Cl2], have been prepared and investigated using different chemical techniques such as elemental analysis, molar conductance, FT-IR, UV-vis spectra and magnetic moment. The obtained chemical analysis data showed the formation of 1:1 (metal: ligand) ratio. The square planar and tetrahedral g...

Environmental and occupational exposures to heavy metals such as methylmercury (MeHg) and cadmium (Cd) pose significant health risks to humans, including neurotoxicity. The underlying mechanisms of their toxicity, however, remain to be fully characterized. Our previous studies with Cd and MeHg have demonstrated that the perturbation of the ubiquitin-proteasome system (UPS) was associated with m...

metal oxides play a very important role in many areas of chemistry, physics and materials science.the metal elements are able to form a large diversity of oxide compounds. in this investigation, wesynthesis sno2 and c,n,s-tridoped sno2 nanoparticles by precipitation method. the synthesizedsno2 and c,n,s-tridoped sno2 nanoparticles were characterized by instrumental analysis methods,such as x-ra...

UNLABELLED Adverse local soft-tissue reactions have been associated with severe osteolysis and implant failure in metal-on-metal total hip arthroplasty (THA). Such a causal relationship has not often been associated with non metal-on-metal bearing surfaces. The purpose of this study was to assess the literature for cases of adverse soft-tissue reactions in non-metal-on-metal bearings in order t...

This broad overview covers the use of gas and liquid chromatography as well as capillary electrophoresis for the determination of metal ions and metalcontaining species, such as organometallic compounds or metalloproteins. We pay particular attention to the latest developments and consider the features of the various detection techniques and applications of the different methods. a 2005 Elsevie...

In this paper, we propose a reliability–mechanical study combination for treating the metal forming process. This combination is based on the augmented Lagrangian method for solving the deterministic case and the response surface method. Our goal is the computation of the failure probability of the frictionless contact problem. Normally, contact problems in mechanics are particularly complex an...
