In this study, porous zinc oxide nano-flakes were successfully synthesized by anodization method on zinc substrate in a 0.025 M NaOH and 0.05 M NH4Cl solution with the voltage of 10 V at room temperature. The field emission scanning electron microscopy’s (FESEM) images show the structural evolution during 90 min of the anodization process. They also demonstrate the dependency of growth of ZnO f...

A series of ZnO/Al2O3 mixed oxide samples with varying Zn/Al ratio is prepared by coprecipitation, ageing, drying, and calcination. Samples are investigated in the state after drying and calcination. The applied methods include X-ray diffraction, solid-state 27Al magic-angle spinning nuclear magnetic resonance spectroscopy, transmission electron microscopy and thermogravimetric experiments coup...

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...

In this work, zinc ferrite magnetic and zinc ferrite-graphene oxide nanocomposite were synthesized through a facile hydrothermal method and dye removal capability as an adsorbent were studied. Fourier transform infrared spectroscopy FT-IR, X-ray diffraction XRD and scanning electron microscopy SEM were used to characterize the synthesized nanocomposite. The UV-Vis results showed that the additi...

In current study, nanoparticles and single crystals of a Zn(II) coordination complex, [Zn(dmph)I2](1), {dmph=2,9-dimethyl-1,10-phenanthroline(neocuproine)}, have been synthesized by the reaction of zinc(II) acetate, KI and neocuproine as ligand in methanol using sonochemical and heat gradient methods, respectively. The nanostructure of 1 was characte...

gas sensitive metal oxide layers used in fabrication of resistive gas sensors are prepared by different deposition techniques. the technical data reported on some basic and practically important specifications of these devices, although fabricated based on the same gas sensitive oxide, are anomalously different. the influence of the fabrication technique used for the deposition of the gas sensi...
