-What is the term nano

The term nano part of the billion;

Valenanomitr is one billionth of a

meter and to imagine the small

nano-meters include the following;

thick hair is one of man 50

Makromtra any 50.000 nm, and

smaller things that man can see

with the naked eye width equal to

about 10,000 nm, When the atoms

are lined up one tenth of the

hydrogen , the length of nano-

meters and one loyal to him of

.something very delicate

It may be useful to recall the following definitions



Nano-scale : the dimensions that includes a length of one

nanometer up to the 100 nm



Nanoscience is the study of properties of molecules and

.compounds that do not exceed their standards of 100 nm



Nanotechnology is the application of these sciences and

.engineering for the production of useful inventions



Cealfred at the nanoscale, or the "Nano Scale" is that most of

the basic properties of materials and machines Kaltusilah

Ahraria or electrical, hardness and melting point depend on

the size (size dependant) is unparalleled in any measure other

than nanotechnology, for example, wire or Mosul nanoscale

size does not necessarily follow Ohm's law equation that links

current and voltage and resistance, it relies on the principle of

the flow of electrons in the wire as the water flows in the river;

Electrons can not pass through the wire with a width of one

atom that the electrons pass through it after the other. Taking

into account the size scale in addition to the basic principles of

chemistry and the physics of electricity and is the key to

.understanding of nanoscience large

Infinitely small



Let's imagine something within our reach, for example, cubic

gold side length of one meter and go with a tool as the length

and breadth, and a rise will have eight cubes along the side of

one of 50 centimeters, and comparing these cubes cube

original, we find that it will carry all its properties such as

color yellow shiny and smooth and the quality of delivery and

the degree of fusion and other characteristics, except for the

monetary value of course, then we'll cut off one of these cubes

to eight other cubes, and will become a side length of one of 25

centimeters and will carry the same characteristics, of course,

and we will repeat this process several times and Sasgr scale at

a time from a centimeter to a millimeter down to micrometer .

And with a matching micro-cutting tool and accurate, we find

that properties will remain as it is and this is a reality

experienced in practical life, Fajsaús article on a scale

micrometer and older do not depend on the size. When we

continue definitely will get what we called earlier the

nanoscale, at this size will change all the characteristics of

material in whole, including the chemical properties; and the

reason for this change is due to the nature of interactions

between the constituent atoms of the element gold, in the large

volume of gold there are no such interactions often It is

therefore concluded that the gold nano-size will do for gold

with a different scale.
