Why are carbon nanotubes an amazing subject? Carbon nanotubes are a very fascinating topic for the reason of its application into our everyday life. Scientists could be able to develop a better tomorrow with the cutting edge technology on nano-science to benefit the majority of the population and to create a brighter future with its life-changing impact. Carbon nanotubes (CNTs) demonstrate remarkable strength to density ratios and unlike any other material in the world.
The notion of using a Space Elevator was first imaged by Russian Scientist Konstantin Tsiolkovsky (the idea came to him by observing the Eiffel Tower located in Paris France). Konstantin is most famous for his design of rocket ship. However, his idea concerning the space elevator could be progress mankind will need to sustain our population. While reading articles about the Nano science topic in a Discover magazine, turns out researchers from the University of Texas have the same opinion to their newest invention concerning about nanotubes with higher tensile strength than steel; which displays its importance is this latest material. Currently researchers brainstorm the subject of the nano-robe material in order to attach it onto the space elevator, a 62,000 mile long robe and being capable to withstand huge impressive storms such as hurricane Sandy due the Carbon nanotubes are so much stronger than steel, and provides real promise for the creation of the space elevator. Someday, once such technology is accomplished, the nano-robe would be able “to lift astronauts, cargo, or even tourists into orbit (Discovermagazine.com).” The science community is predicting that the average person will be one day experiencing space without the need of a space shuttle.
Carbon nanotubes were discovered in the deposits of carbon arc discharge by Japanese researcher Sumio Iijima, in 1991 and expanded the interest in the field of nanotechnology materials. This method was done by carbon target hit by intense laser pulses containing Ni/Co, Nanotubes are collected downstream by flowing inert gas through chamber producing high quality single wall nanotube with a catalyst particles also called the precursor, this process gives us the ability to control the size of the single wall nanotubes. There are different categories of carbon nanotubes such as single wall nanotubes. The structure of carbon nanotubes looks like graphite sheet rolled to form hollow cylindrical tubes. The C-C bonds arrangement in a hexagon shape which makes it among the strongest chemical bonds in the world. The CNTs have a cylindrical wall of average diameter a 1.2nm - 1.4nm. Tried to image a cross section of human hair we could pack 10 billion nanotubes! Yet CNTs have the amazing ability of being 300 times greater than steel. This property allows us to imagine the real possibility of a space elevator.
Multi-wall nanotubes (MWNTs), that is cylinders within cylinders can be achieved by a laser ablation - this technique gives it the...
