Thin film of zinc oxide was prepared by spin coating on pyrex glass using zinc acetate dehydrate, 2-methoxyethanol and monoethanolamine (MEA) as a precursor, solvent and stabilizer respectively. Also, Aluminium-doped thin film of ZnO was prepared by using AlCl3. Deposited thin films were investigated for structural and optical properties using X-ray diffraction (XRD) and UV–VIS-NIR spectrophoto...

BACKGROUND Supra-physiological concentrations of ascorbate, vitamin C, in blood, greater than 1mM, achieved through intravenous administration (IV), are being tested in clinical trials to treat human disease, e.g. cancer. These trials need information on the high levels of ascorbate achieved in blood upon IV administration of pharmacological ascorbate so appropriate clinical decisions can be ma...

Zinc oxide (ZnO) nanopowders were synthesized by the sol–gel method from an ethanol solution of zinc sulfate heptahydrate in the presence of diethylene glycol surfactant. Detailed structural and microstructural investigations were carried out using x-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), field emission scanning electron microscopy (FE-SEM), Fourier tra...

Nano-structure of Co–Mn spinel oxide was prepared by thermal decomposition method using [Co(NH3)4CO3]MnO4 as the precursor. The properties of the synthesized material were characterized by X-Ray Diffraction (XRD), Brunauer-Emmett-Teller (BET), Transmission Electron Microscopy (TEM), surface area measurements, Energy-Dispersive X-ray (EDX) spectroscopy analys...

Nano-sized ZnO was synthesized through the hydroxide precipitation using drop wise method. The variations in resistance of sensing pellet at different temperatures were recorded. The relative resistance was decreased linearly with increasing temperatures over the range, 150°C-260°C. The activation energy of ZnO calculated from Arrhenius plot was found 0.007eV. Temperature response in terms of t...

In this work, growth and assembly of the micro polyhedral zinc oxide was performed using airbubble assisted Triton X100, as a templating agent. In absence of air bubbling in the reactionsystem the nano plate zinc oxide was synthesized. The prepared samples were characterized by Xraydiffraction (XRD), field emission scanning electron microscopy (FE-SEM) and UV-Visspectrop...
