In this article, a simple hydrothermal process without using any structure-directing reagent was used to synthesize ZnO nanostructures with different morphologies including nanorods, nanowires, and nanobrushes.Abstract:
In this study, ZnO nanostructures with different morphologies including nanorods, nanowires, and nanobrushes were synthesized by a simple hydrothermal process without using any structure-directing reagent. The samples were characterized by X-ray diffraction, field emission scanning electron microscopy, and transmission electron microscopy. The influence of the preparation parameters on the morphology of ZnO is discussed. Gas-sensing properties of the materials were investigated. The results reveal that all the prepared nanostructured ZnO powders show high response to ethanol, among which, the three-dimensional nanobrushes show the highest response, demonstrating excellent potentiality for ethanol sensors.read more

Growth mechanism and growth habit of oxide crystals
TL;DR: In this article, the growth mechanism and growth habit of oxide crystals are investigated from a kinetics viewpoint, starting from the hypothesis of growth unit, and a new rule concerning the growth habit is deduced considering the relation between the growth rate and the orientation of the coordination polyhedron at the interface.

Fabrication and optical properties of large-scale uniform zinc oxide nanowire arrays by one-step electrochemical deposition technique
TL;DR: In this paper, the photoluminescence spectrum of the ZnO/AAM assembly system depends on the excitation wavelength in the visible region, which is attributed to different types of oxygen vacancies in the znO nanowires.
