Carbon Nanotubes - The Smallest Tubular Molecules

Another interesting application of nanotubes is the nanothermometer (Fig. 3.7). A carbon nanotube (about 10p.m long and 75 nm in diameter) is filled wifh liquid gallium, which expands in the tube as the temperature increases. Therefore, the level of the gallium in the nanotube changes in proportion to temperature, similar to the mercury in a macroscale thermometer. This nanothermometer should be suitable for use in a wide variety of microenvironments.

Carbon Nanotubes - The Smallest Tubular Molecules A carbon nanotube is carbon-based tube with a diameter that is measured in nanometers and a length of several micrometers. Nanotubes have interesting electronic characteristics that are expected to lead to their widespread use in molecular electronics.
