What is nanotechnology?

If what is nanoscience and nanotechnology? Nanotechnology involves research to discover new properties and behaviour of materials in the dimensions on the scale nanocomposite. And that its dimensions (1 to 100) nm. Nanotechnology is the way in which discoveries made on the nano-scale. It's more than just a collection of several articles with a nanocomposite. It requires the ability to manage and control these materials in a meaningful way.

What is the special thing in nano-scale?

In short, the nano scale materials can have different properties. Some become better electrically or thermally, some become stronger, some magnetic properties have become different, and some reflect light better, and some are changing their colors change size.

Surface area:

Nano-scale materials also possess much greater surface areas of similar sizes for larger-scale materials, this means providing more space for interactions with the material around.

What is the importance of surface area?

By comparing a piece of bubble gum chewed a WAD with this lift chewing gum shaped thin plate as possible, surface, or externally visible space, much more taut piece to piece the Mastication, chewing gum outstretched is likely to dry out and become brittle faster than those the Mastication and because they (outstretched) have more surface contact with the air moving around.

How small a nanometer?

Nanometer determines part of billion of a meter. How small? These are some ways to think about this:

That page 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 towed from 50,000 to 180,000 nanometers

There are 25.400.000 nm in activities.

A nanometer is equal to 1 million millimeter.

Where are the materials with nano-scale?

Nano-meter materials and Nano-there are in nature all around us. The secrets of nature to produce nano-scale construction processes and the scientists hope to imitate. Researchers have already copied the structure nanoparticles for leaf leaves Lotus flower to produce waterproof surfaces used today for work wear, smudge-proof to produce other tissues and other materials, while others imitate the strength and elasticity of spider, which reinforced the natural nanoscale crystals.

Many important functions in life organisms occur in nano scale, that our bodies and the bodies of all animals used natural materials nanocomposite scale, such as proteins and other molecules, to control many systems and processes of our bodies. The typical protein such as hemoglobin, which carries oxygen through the blood stream 5 nanometers in diameter, or 5 parts per billion of a meter.

Nanomaterials is all around us, in fire smoke, volcanic ash, sea spray, as in products arising from combustion processes. Some of these articles put in use for centuries. Material such as gold (nano), used in glass coloured porcelain since the 10th century, but the other 10 centuries requests before they develop the loudspeakers of high power and precision to permit nanomaterials that imagine and call.

What is nano?

Nano-scale objects behave quite differently about its conduct in the larger scales, large scale gold for example is an excellent conductor of heat and electricity, but not to light. But Nano gold particles built properly, start with light absorption and can convert light to heat, heat enough. In fact, this makes it act as a scalpel miniature heat can kill the unwanted cells in the body, such as cancer cells.

Some other articles can yell notoriously stronger when based on the measurement of nanocomposite. For example, carbon nanotubes with a diameter of 0.00001 of Qatar human hair, incredibly powerful. It is used in the manufacture of bicycles, baseball bats, and some auto parts today. Some scientists think that all carbon nanotubes with plastic composite industry much lighter than steel, and at the same time more powerful. Imagine how you can save energy if we replaced some of the metals used in the manufacture of the car such as this compound! The conductive carbon nanotubes for heat and electricity better than any metal, so can be used to protect aircraft from lightning strikes, it can be used in computer circuits.
