TLDR
Aligned zinc oxide nanorods were synthesized directly via a two-step solution approach on an Al2O3 tube, and were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM) as mentioned in this paper.Abstract:
Aligned zinc oxide nanorods were synthesized directly via a two-step solution approach on an Al2O3 tube, and were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The zinc oxide nanorods prepared were uniform with diameters of 10–30 nm and lengths about 1.4 μm. The response Sr (= Ra/Rg) of the aligned zinc oxide nanorod sensor reached 18.29 and 10.41 to 100 ppm ethanol and hydrogen, respectively, which was a two-fold increase compared with that reported in literature, demonstrating the potential for developing stable and sensitive gas sensors.read more

Reversible super-hydrophobicity to super-hydrophilicity transition of aligned ZnO nanorod films
TL;DR: Remarkable surface wettability transition occurs with an inducement of ultraviolet (UV) for aligned ZnO nanorod films and this reversible effect is ascribed to the cooperation of the surface photosensitivity and the aligned nanostructure.
