what are the uses of nano sized wires and tubes? what is the point of them? its for homework!! thank you!!?

Answer 1

When discussing nanowires and nanotubes, what you're usually talking about are carbon nanotubes. These have a number of remarkable properties. They are extraordinarily strong, and because carbon has a low atomic weight they have the greatest strength-to-weight ratio known. Although it has not been achieved in practice, they have a theoretical electrical conductivity over a thousand times better than metals like copper. their thermal conductivity is similarly high. Because of their nature - long, thin rods -they can be processed in such a way that they are all oriented in the same direction. If you hold an oriented bunch like this together with some type of glue, you can make a composite material that has excellent thermal and electrical condictivity from top to bottom, but is a very good insulator from side to side.

Answer 2

the point of them is very simple its new tech that has to be used i think mainly for computers for the moment something to do with buckypaper i may of spelt that wrong its basicly thousends of nano tubes placed together to create a new material wich can be used for processors its benifits include it conducts heat very well and it is half the weight of steel but twohundred and fifty times stronger its applications include its proposeled use in air craft building and also body armor

Answer 3

making anything nano means it can be made alot smaller, for example nano wires can be used in making mobile telephones or perhaps palm top computers. Nano technology simply means making things alot smaller so they can be used in smaller spaces like for example nano technology is now used in surgical procedures, Help this helps.

Answer 4

Because the technology behind carbon nanotubes will give us the Stars !
