and compounds offers the prospect of an even magnified set of properties. Finally, we will describe carbon nanotube applications supporting the idea that the future for the science and technology of carbon nanotubes looks very promising.
Part A 3
Carbon nanotubes are among the amazing objects that science sometimes creates by accident, without meaning to, but that will likely revolutionize the technological landscape of the century ahead. Our society stands to be significantly influenced by carbon nanotubes, shaped by nanotube applications in every aspect, just as silicon-based technology still shapes society today. The world already dreams of spaceelevators tethered by the strongest of cables, hydrogen-powered vehicles, artificial muscles, and so on – feasts that would be made possible by the emerging carbon nanotube science. Of course, nothing is set in stone yet. We are still at the stage of possibilities and potential. The recent example of fullerenes – molecules closely related to nanotubes, whose importance was so anticipated that their discovery in 1985 brought a Nobel Prize to their finders in 1996 although few related applications have actually yet reached the market – teaches us to play the game of enthusiastic predictions with some caution. But in the case of carbon nanotubes, expectations are high. Taking again the example of electronics, the miniaturization of chips is about to reach its lowest limits. Are we going to accept that our video camera, computers, and cellular phones no longer decrease in size and increase in memory eve
