They started with carbon fibers, excellent conductors of electricity, and grew titanium dioxide (TiO2) nanorods, each only 300–500 nanometers in diameter and 1.5–2.0 micrometers in length. These tiny ...

Nanorods are elongated nanostructures with a diameter in the nanometer range and an aspect ratio (length-to-width ratio) greater than one. They are typically characterized by their unique optical, ...
