Copper (II) and Cobalt (II) metal complexes (4a- and 4b-complexes) using Schiff base ligand 1-[(4- butylphenyl)imino]methyl naphthalen-2-ol (3) have been synthesized. The single crystals of Copper (II) and Cobalt (II) complex phosphors were grown and characterized by Fourier-Transform Infrared (FTIR), single crystal X-ray diffraction (XRD), SEM (Scanning Electron Microscope) and EDS (Energy Dispersive X-ray spectroscopy).

Nickel ferrite magnetic nanoparticles (NiFe2O4MNPs) were prepared via the autocombustion assisted solgel method. The efficient catalyst was investigated by FT-IR, XRD, ICP, SEM, and TEM techniques. A one-pot, three-component reaction is reported for the synthesis of substituted 4H -chromenes in the presence of NiFe2O4 MNPs as a reusable catalyst in a green solvent at 40◦C under clean, efficient, and mild conditions. Furthermore, selected products were characterized by FT-IR, 1H NMR, and 13C NMR. The single-crystal X-ray analysis of product 4u was also conclusively confirmed.

A new double molybdate Na2Co2(MoO4)3 was synthesized via solid-state reaction and characterized by single-crystal X-ray diffraction (XRD). This compound is a new member of the lyonsite structure type. It crystallized in the orthorhombic system, space group Pnma with cell parameters a = 5.272(2) Å, b = 10.816(3) Å, and c = 18.064(3) Å. The structure can be described as a three-dimensional framework with hexagonal tunnels in which the Na+ cations lie. The obtained structural model is supported by charge distribution analysis and bond valence sum validation tools.

In this study, synthesis of two new heteronuclear tetracyanonickelate(II) clathrates based on 4-aminopyridine (4AP) and guest water (H2O) molecule and investigation of their structural properties were reported. These clathrates were characterized by using vibration spectroscopy, elemental, thermal analysis and single crystal X-ray diffraction (SC-XRD) techniques. Examining the elemental and spectral data of these clathrates, it was observed that the formulas [Zn(II)(4AP)2Ni(µ-CN)2(CN)2]·6H2O and [Cu(II)(4AP)4Ni(µCN)2(CN)2]·H2O were defined their structures.

In this study, synthesis of two new tetracyanocadmate(II) and tetracyanozincate(II) complexes based on 3-aminopyridine (3AP) and investigation of their structural properties were reported. These complexes were characterized by using vibration spectroscopy, elemental, thermal analysis and single crystal X-ray diffraction (SC-XRD) techniques. Investigation of the elemental, spectral and single crystal data of these complexes showed that the formulas [Cd(3AP)2Zn(μ4 -CN)4]n(1) and [Cd(3AP)2Cd(μ4-CN)4]n(2) fully explained their crystal structure.

The results show that the solid yield reaches 92.4 %, the final product is a single phase with a structure similar to the one of Ca(H2PO4)2.H2O and contains parallelogram-like crystals with a length of about 20 - 50 μm, a width of 20 - 30 μm, and a thickness of a few microns. The formation of monocalcium phosphate has been confirmed by the XRD data and chemical analysis.

Platinum(II) complex of benzimidazole-derived N-heterocyclic carbene with formula [PtCl2(DMSO)(bimy)] was successfully synthesized via one pot reaction between 1,3-diisopropyl benzimidazolium (bimyHBr), Ag2O and [PtCl2(DMSO)] (DMSO = dimethyl sulfoxide). The complex was characterized by means of multinuclear (1H and 13C{1H}) magnetic resonance and single crystal X-ray diffraction (XRD). The UV-Vis absorption spectra of the compound show an absorption shoulder above 300 nm.

Blades and vanes for gas turbines, usually made of Ni-based superalloys, are exposed at very high temperature in severe oxidation and corrosion environments. Nowadays, thermal barrier coating systems (TBCs) have been applied to protect them against such severe working conditions. In this study, Pt and PtIr diffusion coatings on Ni based single crystal superalloys were fabricated by an electroplating method followed by an annealing heat treatment process. The microstructure and phase constitution of the coatings were studied by SEM/EDS and XRD methods.

Influence of mn2 concentration and uv irradiation time on the luminescence properties of mn doped zns nanocrystals. The structure and particle size of the obtained powders were measured by X-ray diffraction (XRD) and scanning electron microscopy (SEM) and shown that all samples are single phase with sphalerite crystal structure and average particle size of about 5-7nm.
