Which form of Carbon is a good conductor of electricity and heat?
Graphite is the type of carbon that conducts electricity but poorly than metal
Objects that do not reflect light well?
Dark colors, especially flat black do not reflect light well. Carbon Nanotubes are considered the worst for reflecting light.
Best conductors of heat?
Carbon, as diamond. And if you want a strange material helium II is the best conductor.
What is a nano-spring?
'Nano-spring' is a casual term for a spring made using nano technology.
Is carbon or tin a better conductor?
This depends on the structure of carbon. In the metastable diamond structure, carbon is an insulator. In a stable graphite structure carbon is known as a 'zero band gap' conductor meaning it will conduct electrons with a small input of energy. A carbon nanotube is one of the best known conductors of electricity because of overlapping 'p orbitals'. Tin is a better conductor of electrons compared to carbon ( generally, unless you are talking about carbon nanotubes). This is due to the band theory of solids. The low energy orbitals of carbon do not 'split' and overlap at large distances. The higher energy orbitals of tin do 'split' and overlap at larger distances allowing for electronic conduction.
What is a nano tube?
A nano tube is a nanometer-scale tube-like structure. (As from Wikipedia) In my words, a very small tube. A nano meter is one BILLIONTH of a meter. Really tiny. There are many types of nano tubes, such as Carbon nano-tubes, Inorganic nano-tubes, DNA nano-tubes and Membrane nano-tubes. Carbon Nano-tubes: A Carbon Nano-tube is a tube like structure that is an allotrope of Carbon. An allotropes are two structures that only differ in the way the molecules are arranged. Such as Diamonds, Graphite and Carbon Nano-tubes are all allotropes of Carbon. Carbon Nano-tubes are very good at conducting electricity Inorganic Nano-tubes: An inorganic nanotube is a cylindrical molecule often composed of metal oxides, and morphologically similar to a carbon nanotube. Inorganic nanotubes have been observed to occur naturally in some mineral deposits. (As from Wikipedia) In my own words, A molecule that is shaped like a tube is if usually made of metal oxides, and has a similar structure to a Carbon nano-tube. DNA Nano-tubes: These are a hard concept to grasp, but very simply, DNA nanotubes are somewhat similar in size and shape to carbon nanotubes, but the carbon nanotubes are stronger and better conductors, whereas the DNA nanotubes are more easily modified and connected to other structures. (As from Wikipedia) So, they are similar is size and shape to Carbon Nano-tubes, but, they are less strong and doesn't conduct electricity as well. But they are easier to modify. Membrane Nano-tubes: Membrane Nano-tubes are long and thin tubes formed from the plasma membrane that connect different animal cell. (As from Wikipedia) Or, long tubes connecting animal cells. Here is where I found this info, I suggest visiting them for more detailed information. Hope this helped. http://en.wikipedia.org/wiki/Nanotubes http://www.futureforall.org/nanotechnology/nanotubes.htm

What is the chemical formula for carbon nanotubes?
Carbon remain carbon.
Which form of carbon is ductile?
graphite carbon nanotubes
Why can carbon nanotubes conduct electricity?
I thought it was because nano tubes are created using graphene which is a single layer of graphite and graphite only bonds with 3 carbon atoms and this leaves one declocalised electron thats free to carry a charge
What element has a macromolecular structure similar to carbon?
Carbon nanotubes
Who invented nanotube?
Although there are numerous instances of people observing carbon nanotubes, most literature credits Sumio Iijima as the discoverer of carbon nanotubes.
What is the structure of nanotubes?
the structure of nanotubes are carbon atoms joint together covalently to form a long tube.
Is carbon nanotubes a type of paper?
No. Paper is cellulose, a carbohydrate usually derived from plant material. Carbon nanotubes are a variant of pure carbon that are used in a variety of high-strength materials.
Which metals is used in paper batteries?
carbon nanotubes
Which are the physical properties of carbon nanotubes?
Strength:Carbon nanotubes are the strongest and stiffest materials yet discovered in terms of tensile strength and elastic modulus respectively.Hardness:Standard single-walled carbon nanotubes can withstand a pressure up to 25 GPa without deformation.
Can carbon nanotubes be used to make bullet proof armor?
This technology is being explored as an option for body armor, but there are no body armor products using carbon nanotubes as yet.
