AISI 316 stainless steels were coated with 250 nm Ni film by electron beam deposition and post-annealed at different temperatures with a nitrogen flow of 600 cm3min-1 nitrogen. The prepared samples were corrosion tested in 1.0 M sulphuric acid solution using potentiodynamic technique. Crystallographic and morphological structure of the samples were analyzedanalysed by X-ray diffraction (XRD) an...

Ti films with the same thickness, deposition angle (near normal) and deposition rate were deposited on glass substrates at room temperature under UHV conditions. Different annealing temperatures 120, 270 and 320 degree Celsius with 7 cm/sec uniform oxygen flow, were used for producing titanium oxide layers. Thin film structures were studied by AFM and XRD methods. During annealing processes rou...

We report a preparation of high-quality cubic PbTe nanocrystals and their assembly into both square-array, two-dimensional patterns and three-dimensional simple cubic super crystals. The influence of oleylamine in the nanocrystal synthesis and core-shell formation through an anion-exchange mechanism was also studied. The simple cubic super crystals together with two-dimensional assembly pattern...

In this work layered copper films with smooth surface were successfully fabricated onto ITO substrate by electrochemical deposition (ECD) and the thickness of the films was nearly 60 nm. The resulting films were characterized by SEM, TEM, AFM, XPS, and XRD. We have investigated the effects of potential and the concentration of additives and found that 2D dendritic-like growth process leaded the...

The near-spherical AgCl micro-crystals were prepared by an ionic liquids-assisted hydrothermal method. The influence of ionic liquids (C(x)MimCl x = 4, 8, 12, 16) on (001) facet growth of AgCl was studied systemically. The composition of the as-prepared samples was characterized by X-ray diffraction (XRD), thermogravimetric analysis (TGA) and FTIR spectra. The morphological structures were char...

Zinc oxide nanoparticles (ZnO NPs) is unique studied semiconductor substance for photocatalytic utilization like light-emitting diodes, solar cells, photo-diode, sensor, and photo-detector. The ZnO ratio of surface to volume as increases with reduces size afford an increase improve the reactivity surface. Among all possible approaches preparation, sol-gel process individual simple synthesis met...

Titanium thin layers with the same deposition conditions were deposited on glass substrates at room temperature. Different annealing temperatures namely, 400 K, 500 K and 600 K with uniform 9 cm /sec oxygen 3 flow were used to produce titanium oxide layers. The nano-structure of layers were studied using AFM and XRD methods. Optical Reflectance were studied by spectrophotometer method. Correlat...

The growth mechanism of 7-80 nm thick CeO2 nanometric epitaxial films, deposited on (001)-YSZ from 2,4-pentadionate solutions, has been investigated using x-ray diffraction (XRD), x-ray reflectivity (XRR), transmission electron microscopy (TEM), x-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM) and reflection high energy electron diffraction (RHEED). The film thickness was t...

SnO2 micro/nano fibers in the rutile structure were synthesized using electrospinning and metallorganic decomposition techniques. Fibers were electrospun using two different precursor solutions, one based on SnCl4 and the other on C22H44O4Sn. The fibers were sintered in air for two hours at 400, 500, 600, 700 and 800oC. SEM, AFM, XRD, XPS and Raman microspectrometry were used to characterize th...
