The application of one-dimensional (1D) V2O5·nH2O nanostructures as pH sensing material was evaluated. 1D V2O5·nH2O nanostructures were obtained by a hydrothermal method with systematic control of morphology forming different nanostructures: nanoribbons, nanowires and nanorods. Deposited onto Au-covered substrates, 1D V2O5·nH2O nanostructures were employed as gate material in pH sensors based o...

We report on various self-assembled In(Ga)As nanostructures by droplet epitaxy on GaAs substrates using molecular beam epitaxy. Depending on the growth condition and index of surfaces, various nanostructures can be fabricated: quantum dots (QDs), ring-like and holed-triangular nanostructures. At near room temperatures, by limiting surface diffusion of adatoms, the size of In droplets suitable f...

in this work, mg-doped zno nanostructures were prepared in water under ultrasonic irradiation for 60 min without using any organic compounds or post preparation treatments. the prepared samples were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem), transmission electron microscopy (tem), energy dispersive analysis of x-ray (edx), diffuse reflectance spectroscopy (drs...

in the present study, a simple, efficient and fast synthetic strategy was reported for the green biosynthesis of silver nanostructures (i.e. nanoroads and nanoparticles) by the extract of suaeda acuminata plant, without any catalyst, template or surfactant. aqueous extracts were obtained by maceration and microwave assisted extraction (mae) methods. in mae procedure, the effect of microwave pow...

A comprehensive study on the structural, electronic and nonlinear optical (NLO) properties of alumina nanostructures (Al2O3)n with n = 2-5 belonging to the groups III and VI dopants carried out by density functional theory. The NBO charges exhibit dopant atoms caused to the increasing charge transfer and introduces acceptor-donor model for NLO response of alumin...
