ABSTRACT

Carbon nanotubes have unique physical and chemical properties that chemists try to raised understand through laboratory research. One of the physical properties of carbon nanotubes is that it’s possible to form them only one atomic layer thick. This means that they will be about 1/50,000th the thickness of a person's hair. Because of the bonding characteristics of carbon atoms, the physical appearance of carbon nanotubes can often resemble rolled up net. One of the interesting physical properties about carbon nanotubes is that once you have two of them which have slightly different physical structures and that they are joined together, the junction between them can function as an electronic device. This electronic behaviour depends upon the structure of the 2 tubes. If they need similar physical and chemical properties then it becomes easier to predict their behavior which might ultimately make them more useful for possible nano sensors. These nano sensors could behave like semiconducting materials in microelectronic circuits, or detect small changes in current, or register chemical reactivity, or changes in atmospheric pressure or temperature. Since nanotube science is comparatively new, scientists from the fields of chemistry, physics and therefore the material sciences are just starting to unlock its mysteries and hypothesize about its potential applications.
