Nanotechnology

History of Nanotechnology

Nanotechnology beyond the late 19th century when the first colloidal science is rooted. The term "nanotechnology" is defined for the first time by Norio Taniguchi, Professor of Tokyo University of Science, in 1974 in his paper. Nanotechnology consists mainly of processing materials through separation, consolidation, and deformation by an atom or a molecule.

Technology now uses the term ‘nano’ in touch and not too far to the objectives related to technology changes and molecular manufacturing proposals, but the term are often led to the idea. So, maybe dangerous "nano bubble" will be formed from the use of such terms by scientists and entrepreneurs to make a profit, regardless of (and probably less) interest in the possibility of change seems to work more visionary and far.

There are also risks of nanotechnology is the risk to health and the environment arising from nano particles and matter, health and environmental risks caused by particles and nano materials, the risks caused by the manufacture or production of molecules (or other nano technology) risks caused by manufacturing or production of molecules (or other nano technology) and the risk that comes from the community itself. the risk that comes from the community itself.

Benefits of Nanotechnology in Human Life

Health Care

In the health sector, through nanotechnology can be created "nanomachines" that is injected into the body to repair tissue or organ damage. Nanotechnology involves the development of technology in the nanometer scale, usually 0.1 to 100 nm (a nanometer is one thousandth of a micrometer or one millionth of a millimeter). For industrial metals, can be created an inexpensive alternative metal material, lightweight and efficient, which can reduce the cost of production of vehicles, machinery and others. Nanotechnology has been able to reverse the drug to achieve the target with the right dose, including the opportunity to overcome severe disease such as tumor, cancer, HIV, and others.

Industry

A nanotechnology application in industry is extensive. With nanotechnology, we can make the spacecraft from composite materials that are lighter but has the strength of steel. We also can produce a car that weighs only 50 pounds. Do not miss the fashion industry. Warm coat is very thin and light could become a trend in the future with the help of nanotechnology.

Space Plane

Nanotechnology also been successful in thrusting a fantastic material that is very lightweight, but its strength is 100 times stronger than steel! This great material named Carbon Nano-Tube (CNT). This material is composed of carbon atoms (C), such as graphite and diamond.

The next thing that is needed is something that is quite heavy in orbit around the earth. Asteroids can be utilized for this purpose. Asteroid serves as a stabilizing load cable and geostationary satellites orbiting it. Without load stabilizer (counterweight), cable and satellite could fall on earth due to gravity interested, though construction material is very lightweight material. The asteroid will be connected to the satellite using the same cable. Asteroids can be instructed to orbit at a certain altitude around the earth by shooting him with a missile. Collision with these missiles can shift the position of the asteroid that is on the earth's gravity range. Thus asteroid will continue to orbit around the earth at the same height. Building construction plans and pass / cord appears to have been quite good. Lift off into space in the form of a spacecraft that will carry passengers from Earth to orbiting satellites. The aircraft is different from the spacecraft, which is currently used by astronauts to carry out their missions.

Earthquake Resistant Technology

Nanotechnology promotes earthquake-resistant and sturdy concrete. Construction of the building to be twice as strong, earthquake-resistant, water-resistant marine grade construction with the discovery nanosilika, a type of mineral that is abundant in Indonesia and processed through nanotechnology mix concrete with 10 percent of nano-silica, the force increased to twice double.

Information Technology

World informatics and computer or electronics can enjoy their quantum capable of transmitting data at very high speed. In future supercomputers composed of very small chip, but can save millions of times more data than the computers we use today. So small supercomputers, we may only be able to see it with a microscope or electron. The role of nanotechnology in the development of information technology (IT, information technology), is not in doubt. Increasing computer speed over time, increasing capacity hard drives and memory, the smaller and increasing functionality of mobile phones, are concrete examples of nanotechnology products in the field of IT.

Description of convenience, when the size of the transistors can be made smaller than the number density of transistors on the same chip size will automatically be bigger. In the manufacture of LSI (large scale integrated as far as possible the number of transistors in a chip can be reproduced. It is estimated that in the future, in line with the continued advancement of nanotechnology, transistor sizes continue to be decreases in accordance with Moore's law and processor type 45 nm will enter the market in 2007, and subsequently in 2009 will be 32 nm processor.
