In this study, nickel (Ni) thin films were deposited at two different angles (65o and 85o) using Glancing Angle Deposition technique, to the thicknesses of 60 - 290 nm. Structural analysis was performed by scanning electron microscopy X-ray diffraction, while spectroscopic ellipsometry used for investigation optical properties. Electrical resitivity samples determined four-point probe method. s...

cupper oxide structures with a variety of novel morphologies are synthesized using cupper foil as substrate via a solution route. the structure, morphology and phase of the as-synthesized nanostructures are analyzed by various techniques. sem images show gradual development of hierarchical structures of copper oxide with different morphology. in order to study the effect of reaction time and te...

in this pepper fe2o3 nanoparticles were synthesized via a fast microwave method. then fe2o3-tio2 nanocomposites were synthesized by a sonochemical-assisted method. the prepared products were characterized by x-ray diffraction pattern, scanning electron microscopy and fourier transform infrared spectroscopy. the photocatalytic behaviour of fe2o3-tio2 nanocomposites was evaluated using the degrad...

NiCr2O4 normal spinel nanostructures were prepared via hydrothermal treatment at 180 °C for 12 h in the presence of cetyltrimethylammonium bromide (CTAB), sodium dodecyl sulphate (SDS) and poly vinylpyrrolidone-25000 (PVP-25000) as capping agents and subsequent calcination process at 500 °C for 3 h . In this method, [Ni(en)2(H2O)...

A continuous electrocatalytic reactor offers a promising method for producing fuels and value-added chemicals via hydrogenation of biomass-derived compounds. However, such processes require better understanding the impact different types active electrodes reaction conditions on biomass conversion product selectivity. In this work, Ni1−xPdx (x = 0.25, 0.20, 0.15) alloyed nanostructures were synt...

objective(s): according to the unique properties of magnetic nanoparticles, nickel metal-organic frameworks (mof) was synthesized successfully by ultrasound irradiation. metal-organic frameworks (mofs) are organic–inorganic hybrid extended networks that are constructed via covalent linkages between metal ions/metal clusters and organic ligands called a linker. materials and methods: the nanopar...
