Zinc oxide (ZnO) nanostructure was successfully synthesized on an alumina substrate by the hydrothermal method. The method consists of two stages: preparation seeding layers and growth ZnO nanostructures. 0.4 M Acetate Dihydrate (Zn(CH3COO)2·2H2O) 3 Sodium Hydroxide (NaOH) were used as precursors. process carried out at 90 °C for 4 hours. Morphological characterization nanostructures conducted ...

Nanostructured semiconductor materials are considered potential candidates for the degradation of textile wastewater via photocatalytic process. This study aims to produce hexagonal gallium nitride (GaN) nanoplates and zinc oxide (ZnO) nanoparticles in a deionized water environment utilizing one-step arc discharge Detailed characterization samples has been completed scanning electron microscope...

In this research work, ZnO nanotubes were fabricated on a gold coated glass substrate through chemical etching by the aqueous chemical growth method. For the first time a nanostructure-based iodide ion selective electrode was developed. The ZnO nanotubes were functionalized with miconazole ion exchanger and the electromotive force (EMF) was measured by the potentiometric method. The iodide ion ...

ZnO nanosheets are a relatively new form of nanostructure and have demonstrated potential as gas-sensing devices and dye sensitised solar cells. For integration into other devices, and when used as gas sensors, the nanosheets are often heated. Here we study the effect of vacuum annealing on the electrical transport properties of ZnO nanosheets in order to understand the role of heating in devic...

In this paper, we adapted the Stranski-Krastanow (SK) mode to the heteroepitaxial growth of NWs and suggested three general growth modes (SK, island SK, and coherent SK) covering all phenomena observed from nanostructures epitaxially grown on single crystal substrates. A strain versus dislocation (SVD) model was also established to define these three modes. The SVD model analyzes the competitio...
