| 11. | :I don't see why you need carbon nanotubes.
|
| 12. | Different single-wall carbon nanotube diameter distributions can be synthesized.
|
| 13. | Without the plasma, the resulting nanotubes are often randomly oriented.
|
| 14. | In 2002, he extended the same reaction to carbon nanotubes.
|
| 15. | Nanotubes are not the only approach to building ultratiny circuits.
|
| 16. | In May, IBM announced that its nanotube transistors outperformed silicon transistors.
|
| 17. | Nanotubes are sheets of carbon atoms rolled into a tube.
|
| 18. | They are called nanotubes because they are nanometer in size.
|
| 19. | This was followed by dramatic changes in the structure of the nanotube.
|
| 20. | The toxicity of carbon nanotubes has been an important question in nanotechnology.
