Nanostructured hematite thin films are doped with zirconium successfully and also modified by introducing CNT using sol-gel method for their implementation as photo-electrode in photo-electrochemical (PEC) cell for hydrogen generation. XRD, UV-visible spectroscopy and PEC study techniques are used to characterize the thin films. The PEC responses of thin films are improved by introducing carbon...

In this work, nanostructured TiO2 and Cr-doped TiO2 thin films were deposited on glass substrate through sonochemical-chemical vapor deposition (CVD) method. The resulting thin films were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), UV-visible absorption spectroscopy, and photoluminescence spectroscopy techniques. The TiO2 thin film has nanocubic morphology and ...

We have studied by Spot Profile Analysis Low Energy Electron Diffraction (SPALEED) and Auger Electron Spectroscopy (AES) Ni-Al alloyed layers formed by annealing, around 780 K, Al deposits on a stepped Ni(111) surface. The surface structure and composition of the thin epitaxial Ni3Al and NiAl films, obtained respectively below and above a critical Al initial coverage c θ , differ markedly from ...

Using the Langmuir probe method, the reactive plasma parameters were studied in different ratios of oxygen and nitrogen concentrations in a DC cylindrical discharge device.The plasma parameters such as plasma potential, electron density and electron temperature wereextracted from the current-voltage characteristic’s curve of Langmuir probe to find the optimum conditions for deposit the oxy...

Thin Ni0.5 Zn0.5 Fe2 O4 ferrite films were grown on different condition on different substrates using pulsed laser deposition technique. Studying the influence of the energy of the laser beam, of the O2 pressure, of the substrate temperature, and of the distance between the target and the substrate on the microstructure and on the magnetic properties were established optimal conditions for PLD ...

Thin films of Nickel Phthalocyanine (NiPc) are prepared of a base pressure of 10 m bar using Edwards 306 system of thermal evaporation technique .The films are deposited on to glass substrate at various thickness (50, 265 , 350) nm. The optical properties and spectral behavior of NiPc films as a function of thickness were studied at room temperature using UV Visible – NIR absorption spectra. In...

We have developed a convenient and effective XRF analysis procedure for trace amount of K, Ca, V, Mn, Fe, Ni, Cu, Zn, Cd, and Pb in environmental waters by using a preconcentration using the natural polymer (agar). The thin agar film was prepared by drying a homogeneous agar gel after mixing the aqueous sample solution with the agar powder. XRF analysis of the preconcentrated thin agar films co...

Lanthanum zirconate (LZO) films from water-based precursors were deposited on Ni-5%W tape by chemical solution deposition. The buffer capacity of these layers includes the prevention of Ni oxidation of the substrate and Ni penetration towards the YBCO film which is detrimental for the superconducting properties. X-ray Photoelectron Spectroscopy depth profiling was used to study the barrier effi...
