Nano Technology
Carbon Nanotubes

Carbon allotrope.
132,000,000:1 - length to diameter ratio
Hightest weight to strength ratio, creating aircrafts.
Penetrates cell membranes, cancer treatment.
Sensors to detect chemical vapours.
Nanotechnology, or, as it is sometimes called, molecular manufacturing.
Dimensions and tolerances in the range of 0.1 nanometer (nm) to 100 nm play a critical role.
Nanotechnology is often discussed together with micro-electromechanical systems ( MEMS ), a subject that usually includes nanotechnology but may also include technologies higher than the molecular level.
These are just few applications and as the time zips by, a new use is given rise and it is being brought into usage. The advancement takes place in this field as long as we live.

The branch of technology that deals with dimensions and tolerances of less than 100 nanometres, especially the manipulation of individual atoms and molecules.
The future of the world
The concepts of nanotechnology were first discussed in 1959 by Richard Feynman.
The term "nano-technology" was first used by Norio Taniguchi in 1974.
The invention of the scanning tunneling microscope in 1981 was successfully used to manipulate individual atoms in 1989.

Fullerenes were discovered in 1985. C60 was not initially described as nanotechnology; the term was used regarding subsequent work with related graphene tubes which suggested potential applications for nanoscale electronics and devices.
Governments moved to promote and fund research into nanotechnology, such as in the U.S. with the National Nanotechnology Initiative, which formalized a size-based definition of nanotechnology and established funding for research on the nanoscale.
By the mid-2000s new and serious scientific attention began to flourish. Projects emerged to produce nanotechnology roadmaps which center on atomically precise manipulation of matter and discuss existing and projected capabilities, goals, and applications.
One nanometer is a billionth of a meter, or 10-9 of a meter. Here are a few illustrative examples:

There are 25,400,000 nanometers in an inch.
A sheet of newspaper is about 100,000 nanometers thick
On a comparative scale, if a marble were a nanometer, then one meter would be the size of the Earth
Nanoscience and nanotechnology involve the ability to see and to control individual atoms and molecules. Everything on Earth is made up of atoms—the food we eat, the clothes we wear, the buildings and houses we live in, and our own bodies.
Practical Usage and application
Nanomaterials with fast ion transport are related also to nanoionics and nanoelectronics.
Nanoscale materials can also be used for bulk applications.
Progress has been made in using these materials for medical applications.
Nanoscale materials such as nanopillars are sometimes used in solar cells.
Development of applications incorporating semiconductor nanoparticles to be used in the next generation of products.
Recent application of nanomaterials include a range of biomedical applications, such as tissue engineering, drug delivery, and biosensors
Few more applications
Arrangement of carbon molecules.
Originally, it was fabricated as a way to handle carbon nanotubes, but it developed into applications by several research groups, showing promise as vehicle armor, personal armor, and next-generation electronics and displays.
When stacked and compressed, it is 500x stronger and 0.1 times lighter. High thermal conductivity.
