In nanotechnology, nanorods are one morphology of nanoscale objects. Each of their dimensions range from 1–100nm. They may be synthesized from metals or semiconducting materials. Standard aspect ratios (length divided by width) are 3-5. Nanorods are produced by direct chemical synthesis. A combination of ligands act as shape control agents and bond to different facets of the nanorod with different strengths. This allows different faces of the nanorod to grow at different rates, producing an elongated object. Buckminsterfullerene C60, also known as the buckyball, is the simplest of the carbon structures known as fullerenes. ... To help compare different orders of magnitudes this page lists lengths between 10-9 m (metre) and 10-8 m (1 nm and 10 nm). ... The aspect ratio of an image is its displayed width divided by its height (usually expressed as x:y or x×y, with the joining colon or multiplication symbol articulated as the preposition by or sometimes to). For instance, the aspect ratio of a traditional television screen is 4:3... In chemistry, chemical synthesis is purposeful execution of chemical reactions in order to get a product, or several products. ... In chemistry, a ligand is an atom, ion, or molecule (see also: functional group) that generally donates one or more of its electrons through a coordinate covalent bond to, or shares its electrons through a covalent bond with, one or more central atoms or ions (these ligands act as a...
The applications of nanorods are diverse, ranging from display technologies (the reflectivity of the rods can be changed by changing their orientation with an applied electric field) to microelectromechanical systems (MEMS).
