Mixtures of a copper complex and copper fine particles as copper-based metal-organic decomposition (MOD) dispersions have been demonstrated to be effective for low-temperature sintering of conductive copper film. However, the copper particle size effect on decomposition process of the dispersion during heating and the effect of organic residues on the resistivity have not been studied. In this ...

the openings of copper converter in sarcheshmeh copper complex in iranis made of a heat resisting austenitic steel (fe-25cr-12ni) and many failures have been reported. understanding the failure mechanism of the alloy helps to develop better alloys for similar complex environments. samples of as-cast alloy and those taken from failed ones were examined. optical microscopy (om), x-ray diffraction...

A simple and sensitive extraction-fluorimetric method for the determination of copper is reported. The 1,7-diaza-15-crown-5-copper-rose Bengal (DA15C5-Cu-RB) ternary complex is quantitatively extracted into chloroform, diluted with ammoniacal acetone and its fluorescence intensity is measured at 570 nm with excitation at 540 nm. A linear calibration graph was obtained over the copper concen...

During the last 50 years, formation of the highly chromogenic copper cuprizone complex has been exploited for spectrophotometric determinations of copper although the precise chemical nature of the resulting species has never been ascertained; we eventually show here, in contrast to current opinion, that copper cuprizone is a copper(III)complex.

Background & Aims of the Study: Welder’s exposure to welding fumes can cause occupational diseases. The current study sought to examine exposure to welding fumes among welders who work in the repair shop of Sarcheshmeh Copper Complex and design a local exhaust ventilation system to control exposure to welding fumes. Materials & Methods: This applied analytical study was co...

A selected solid complex of the Schiff base ligand derived from Glutaric anhydride with Cu(II) ion was synthesized and characterized by FT-IR, Electronic, ESR Spectral Analyses, Magnetic susceptibility and Molar Conductance Measurements. The disappearance of ν(O-H) hydroxyl band of the phenolic and the lowering shift of the stretching frequency of the ν(CH=N) azomethine band in the ligand after...

A novel copper(II) complex of quinolin-4(3H)-one derived Schiff base ligand was synthesized and characterized by elemental analyses, IR, 1H-NMR, MS, UV–Vis, magnetic moments, conductance measurements and thermal studies. The DNA binding and nuclease activities of copper(II) complex was performed. key words: Copper(II) complex; spectral studies; DNA interaction studies. received: February 02, 20...

A new copper(II) complex with formulae of [Cu(buobb)(2)](pic)(2), where buobb stands for the ligand of 1,3-bis(1- butylbenzimidazol-2-yl)-2-oxopropane and pic represents 2,4,6-trinitrophenol, has been synthesized and characterized by elemental analyses, molar conductivity, IR, UV-Vis spectra measurements, and cyclic voltammetry. The crystal structure of the copper(II) complex has been determine...

in this work we introduce a practical use of synthesized schiff base metal complex in sensing application. a new perchlorate-selective electrode based on the complex n, n'-4-nitro-phenylmethanebis-(salicylaldiminato) copper (ii) [cul] as the membrane carrier was developed. the electrode exhibits a good  nernstian slope of -55.0 ± 1.0 mv/decade and a linear range of  for perchlorate. the limit o...
