Rectangular structure of manganese oxide nanowires

A new form of 1D nanomaterials is reported. Solid-state synthesis of manganese oxide nanowires is accompanied by bunching of individual nanowires. It was found that a peculiar structure of individual nanowires is formed in the course of this synthesis. In this case, nanowires have rectangular shape instead of conventional cylindrical shape. In fact, each individual nanowire consists of smaller ingredients, which are sheet-like nanoribbons. Of course, these nanoribbons are closely packed and can only be distinguished on broken heads of nanowires. Both SEM and TEM results confirm this novel structure. High resolution AFM with scanning area of about one individual nanowire was also employed to visualize rectangular structure of these nanowires with high resolution.
