Self-Assembled Nano Ring Structures
How are these ring structures formed? What is the driving force for these curved structures? Is there any common feature for the following structures with diverse chemical origins (including inorganic and organic compounds, polyelectrolytes, bundled CNT)?

Single-Crystal Nanorings Formed by Epitaxial Self-Coiling of Polar nanobelts

Single-Crystal Nanorings
The most common nano-structures are nanotubes and nanowires, but researchers have also created other nano-structures - such as these 'nanorings'. Nanorings of zinc oxide can form spontaneously under certain conditions. Electrostatic forces seem to cause a nanobelt to curve, while short range chemical bonding fuses the end, creating a single crystal ring. Zinc oxide nanorings formed by self-coiling of nanobelts may be useful in research and in the production of nanoscale devices.
