"nano" is a number pre-fix meaning one-billionth. That is, an object with a length of one nano-meter would be .000000001 meter long. You are probably thinking of "nano-technology" which refers to technology for working with and building things that consists of only a few molecules or atoms. I'm not sure what you would mean by "nan-materials". Since a "nan-structure" would, as I said, consist of only a few molecules, there isn't much "material" to it. So far "nano-technology" consists primarily of tiny "bottles" that hold a few molecules of a drug or filters with pores one or two molecules large.

Not sure if this will help much, but you can look at this article and go from there: http://en.wikipedia.org/wiki/Carbon_nanotube#Synthesis

As has been said "nano" simply refers to a measurement on the order of 1e-9 metres. Nanoscience is any science dealing with objects at this scale, http://en.wikipedia.org/wiki/Nanotechnology" is one that has been specifically engineered on the nanoscale and has at least one dimension between 1 and 100 nanometres.
There is no such thing as a "nano phase" only nano size. Carbon at the nanosize could be tiny amounts of graphite, diamond etc however in the nanotechnology field there is great interest in using http://en.wikipedia.org/wiki/Carbon_nanotube" for various uses.

Nano is just a measurement prefix. Alone itself it does not mean anything. However, nanometer, nanofarad etc. make sense.
If you mean nanotechnology it is the science and technology of materials of size ranging between 100 nm - 1 nm. They are generally called mesoscopic systems. Carbon Nanotube is just one of them. others include ZnO nanostructures. Nanopore DNA detector. Nanoclustures of Si, Ag, Au etc.
I'll state a few use of them? Carbon Nanotubes (CNT) can be used as chemical sensors, CNTFETs, energy storage, high mechanical strength devices etc. ZnO nanoparticles make colorless sunscreen.
We have to apply quantum physics in nanoscale systems as in that small dimensions the electrons behave quantum mechanically.
FAQ: What is nano? how to obtain nano material ?
1. What is nano?
Nano refers to the prefix "nano," which means one billionth. In the scientific field, nano refers to the study and manipulation of materials on a nanoscale, which is one billionth of a meter.
2. How is nano material obtained?
Nano materials can be obtained through various methods such as top-down and bottom-up approaches. Top-down approaches involve breaking down larger materials into smaller ones, while bottom-up approaches involve building up materials from atoms and molecules.
3. What are some applications of nano materials?
Nano materials have a wide range of applications in various fields such as medicine, electronics, energy, and environmental remediation. Some examples include drug delivery systems, nanosensors, and nanocomposites for stronger and lighter materials.
4. What are the potential risks of working with nano materials?
There is still ongoing research on the potential risks of working with nano materials. Some concerns include potential toxicity and environmental impacts. It is important to handle and dispose of nano materials properly and follow safety protocols when working with them.
5. How is nano technology impacting our daily lives?
Nano technology has already had a significant impact on our daily lives in various ways. For example, it has led to advancements in electronics, making devices smaller and more efficient. It has also led to the development of new medical treatments and improved materials for everyday use.
