What is nanoscience and nanotechnology?
Includes nanoscience research to discover new behaviors and properties of materials at the nanoscale dimensions. That almost every dimension (from 1 to 100) nm. Nanotechnology is the way in which the discoveries made at the nanoscale to work. It's more than just a collection of several materials with nanoscale. It requires the ability to handle and control these materials in a meaningful way.
What is so special in the nanoscale?
In short, the materials in the nanoscale can possess different properties. Some of the best become electrically or thermally conductive, some of them become stronger, some of which have become a different magnetic properties, and some reflect light better, and some of them change colors change size.
Surface area
Nanoscale materials also have surface areas much larger than the similar sizes of materials with a larger scale, this means providing more space for interactions with the material around it.
What is the importance of surface area?
Comparing a piece of chewing gum (chewing gum) chew the form is filled with gum lift the plate in the form of thin as possible, roof, or external visual space, a much greater piece of a piece of tight Almamadogp, the extended chewing gum is likely to dry out and become brittle faster than the Almamadogp because it (extended) have a greater surface contact with the air moving around.
How small is a nanometer?
ways to think about this:
The sheet of paper is 100,000 nanometers thick.
Blonde hair with a diameter of probably 15,000 to 50,000 nm, but the black hair is likely to be the diameter of 50.000 to 180.000 nm
There are 25,400,000 nanometers in an inch each.
A nanometer is equivalent to 1 million of a millimeter.

Where are the material of the nanoscale?
Nanoscale materials and nanoscale effect are found in nature all around us. Secrets of nature for the construction of nanoscale processes and mechanism producing scientists hope to imitate them. The researchers previously copied to the nano-structure of the lotus leaf to produce a surface water repellent used on clothing for the work of anti-stain, for the production of other tissues, and other materials, while others imitate the power and flexibility of a spider's web, which reinforced the natural nano-crystals.
Many of the important functions in the life of organisms occur along the nanoscale, that our bodies and bodies of all animals use natural materials with nanoscale, such as proteins and other molecules, to control many of the systems and processes that our bodies. The model protein such as hemoglobin, which carries oxygen through the blood stream with a diameter of 5 nm, or 5 parts per billion of a meter.
Nanomaterials takes us from every side, in the smoke of fire, volcanic ash, sea spray, as in the products resulting from combustion processes. Some of these materials and put in use since centuries. The material such as gold (nanoscale), used in stained glass and ceramics since the tenth century, but other requests 10 centuries before they develop high-power loudspeakers and precision equipment to allow the nanomaterials to imagine and call.
