In this study, complexes of manganese (II) and zinc(II) with ligands (salicylic acid cysteine) [MnL2(H2O)2]2H2O, [ZnL2(H2O)2]2H2O have been synthesized. It is shown that the composition obtained depends on ratio initial components. The structure studied by elemental, X-ray phase analysis, (DLS)method, UV-VIS spectroscopy, IR spectral thermogravimetric analysis. method UV spectroscopy has show i...

The impact factor of ZnSe thin films in an aqueous solution zinc acetate and hydrazine hydrate (HH) using the non-toxic complexing agent EDTA along with were annealed at 200, 300, 400°C. This research aimed to employed XRD analysis, optical measurements, electrical resistivity measurements study films, respectively. use these complementary techniques allowed for a compressive understanding effe...

As technology is scaled down to 5 nm or even smaller, ruthenium (Ru) will most likely be chosen as the next generation barrier material for copper interconnects in integrated circuits (ICs). Recently, higher removal rate of Ru materials chemical mechanical polishing (CMP) has become a major issue. In this paper, diethylene triaminepentaacetic acid pentapotassium salt (DTPA-5K) was introduced ne...

Selective membranes containing a few micrograms of various complexing reagents in a polyvinyl chloride (PVC) matrix were produced in order to determine low uranium concentrations in water. The membranes were produced on the surfaces of quartz glasses, and immersed in water solutions containing uranium salts (5 - 50 ng/mL). By the end of the equilibration time, the membranes were left to dry and...

A calculational method is developed for spectrophotometric determination of stoichiometrics and individual equilibrium constants in the complexing of metal ions with metallochromic indicators. Implicit expressions are developed for the calculation of all parameters necessary to describe mixtures of 1 : 1, 1 : 2 and 2 : 1 metal-indicator complexes. The analysis of titration curves entails a seri...
