Potentiostatic Deposition of ZnO Nanowires: Effect of Applied Potential and Z...IJRES Journal
In this work we report on potentiostatic deposition of Zinc oxide (ZnO) nanowires on fluorine-doped tin oxide (FTO) covered glass substrates from electroreduction of molecular oxygen. The influence of applied deposition potential, and the concentrations of zinc precursor (ZnCl2) on the properties of ZnO nanowires was investigated.SEM results revealed that ZnO nanowires electrodeposited at applied potential -0.85Vhave high density and good alignment. The diameters and densities of the electrodeposited ZnO nanowires are strongly dependent on the zinc ion concentrations and well aligned nanowires with uniform diameter can be obtained when the concentration of zinc ions is between 0.5 mM and 1 mM.
This presentation is a simple explain of Nano-springs which introduce this Nano-materials easily. You can use this PPTx File to present in your class and seminars as well. We prepare this file to present in Tabriz University of Medical Sciences when We were MSc Medical Nanotechnology student. It will be useful for you too.

This module is designed to provide an introduction into the basic physics of a special class of materials : functional oxides, in specific conducting oxides for example semiconductor, photocatalyst, superconductor, electrochromic, noncentrosymmetric, ionic conductor, magnetic and magnetoresistance oxides.
It will cover several essential topics on the crystal structure of the functional oxides and relating the structure to the intriguing properties that the oxides have. In this module, the synthesis, preparation and characterisation of several functional oxides (with properties stated above) will be elucidated. Part of the course will focus on the development of functional oxide in nanoscale.
Overviews on the current and possible future technological applications of the functional oxides and other issues relevant for applications will be explored and presented via several case studies that will be presented and discussed. The ultimate aim of this course is to evoke interest of participants in this fascinating class of materials and also to equip them with essential knowledge on the pressing fundamental challenges in the formation, synthesis and applications of electronic functional oxides.

An Research Article on Fabrication and Characterization of Nickel Oxide Coate...ijtsrd
In this paper we have produced NiO thin film based solar cells. The NiO thin film was then studied for their structural, optical and electrical properties. By the help of these results we have capable to know about the structure of NiO the phase purity of the thin film X ray diffraction XRD pattern of NiO showed the diffraction planes corresponding to cubic phase respectively. The optical properties showed that with the increase in the deposition time of NiO the energy band gap varied between 3.1 to 3.24 eV. In the end, IV characteristics of the thin films were obtained by the help of matlab in the presence of light as will as dark region.

Optical and Dielectric Studies on Semiorganic Nonlinear Optical Crystal by So...ijrap
The field of nonlinear optics became practically a reality after the invention of laser. High performance electro-optic switching elements for telecommunication and optical information processing are based on materials with high nonlinear optical (NLO) properties. Single crystals of nonlinear optical material Llysine sulphate (LLS) are grown by slow evaporation technique. The crystal structure and lattice parameters are determined for the grown crystal by single X-ray diffraction studies. The wide transparency range of the crystals in the visible region of the electromagnetic spectrum is identified by the UV-Vis-NIR technique. The mechanical property of the grown crystal is determined by Vicker’s microhardness test. It is observed from the microhardness studies of the grown crystals that the hardness increases with increase in load. Meyer’s index n is calculated which proves that the material belongs to soft material category. The dielectric constant and dielectric loss are calculated by varying the frequencies at room temperature. The emission of green light on passing the Nd: YAG laser confirms the second harmonic generation (SHG) property of the crystals .The SHG efficiency of the crystals are found to be better than that of Potassium Di hydrogen Phosphate (KDP)
Over five years research and development experience in silicon wafer based solar photovoltaics. Specialized in characterization of silicon wafer and solar cells. Developed and establish methods for the measurement of diffusion length in higher lifetime wafers, front and back surface recombination in silicon solar cell.

surface energy and nanostructure growth.
Pure ZnO and EU doped ZnO thin films will be deposited by pulsed laser deposition

properties of these films.
