Recently, zinc oxide (ZnO) nanowires have drawn major interest because of their semiconducting nature and unique optical and piezoelectric properties. Various applications for ZnO nanowires have been conceived, including the next generation of field effect transistors, light emitting diodes, sensors and resonators. ZnO nanowires are also envisioned as nanogenerators by exploiting the coupling o...

In this work, ZnO/SiO2 nanoparticles were prepared using sol-gel method, and platinum particles were loaded on ZnO/SiO2 nanoparticles by photoreductive method. Samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR). The XRD patterns showed that the zinc oxide samples have a wurtzite structure (hexagonal phase...

Pulsed laser ablation in liquid was employed to synthesize zinc oxide (ZnO) nanocolloidal suspension. Colloidal ZnO nanocrystals are synthesized by pulsed laser ablation of high purity zinc target in double distilled water with various laser fluences at RT. UV–visible absorption and transmission electron microscope are used for the characterization of colloidal ZnO nanoparticles (NPs). The opti...

Nitric oxide (NO) has been found to function in enhancing plant tolerance to various environmental stresses. However, role of NO in relieving zinc oxide nanoparticles (ZnO NPs)-induced phytotoxicity remains unknown. Here, sodium nitroprusside (SNP, a NO donor) was used to investigate the possible roles and the regulatory mechanisms of NO in counteracting ZnO NPs toxicity in rice seedlings. Our ...

Iliadis Department of Electrical and Computer Engineering and Computer Growth of high quality zinc oxide thin films on silicon substrates is particularly important because it combines the unique features of zinc oxide (ZnO...

background and objectives: zinc oxide (zno) nano-particles have been proven to have strong antibacterial activity against food borne pathogens. the practical applications of different concentrations (control, 0, 1, 2, 4, 6 and 8 mm) of zno suspensions containing 1% acetic acid were investigated against the pathogenic bacteria like staphylococcus aureus. materials and methods: the projects of la...

A viral β-annulus peptide connected with a zinc oxide (ZnO)-binding sequence (HCVAHR) at its N-terminal was synthesized, and the inclusion behavior of quantum-sized ZnO nanoparticles into the peptide nanocapsules formed by self-assembly of the peptide in water was investigated. Dynamic light scattering (DLS) measurements showed that ZnO nanoparticles (approximately 10 nm) in the presence of the...

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...

Zinc oxide nanoparticles are highly sensitive towards phosphate ions even at pH 7. Buffer solutions and cell culture media containing phosphate ions are able to destroy ZnO nanoparticles within a time span from less than one hour to one day. The driving force of the reaction is the formation of zinc phosphate of very low solubility. The morphology of the zinc oxide particles has only a minor in...
