We calculated the mechanical properties of a ZnO nanorod within forest-like samples. According to the results for ZnO nanorods, we extended the calculation method to determine the mechanical properties of a TiO2 nanotube (TN) extracted from a forest densely grown by anodization on a Ti substrate. The Euler model was adopted, and critical-load measurements were performed during vertical-compression experiments involving nanoindentation. We measured the elastic moduli of a single ZnO nanorod and a single TN as similar to 190 and similar to 27 GPa, respectively. Thus, we suggested a method for determining the mechaical properties of individual entities in one-dimensional materials grown in bundles. (C) 2017 Acta Materialia Inc Published by Elsevier Ltd.
