Technology Nanotechnology (Nanotechnology) 1. Introduction The 21st century can be called the Millennium sophisticated information society. As to be seen in the rapid growth of the Internet field, and high-speed information transmission is granted, shoe racks there is a degree of integration of such information delivery media situation in the development shoe racks of new materials is demanded by their limitations. As the size of the fine nano-materials and the circumstances and emerge as a core material for his composition application technology development and industrialization is determined that desperately needed time. This material, as well as materials science and electronics, life science, if the application is technologically far mankind has achieved so far is because many people are convinced that it would lead to enormous changes difficult to even predict. Research areas for the "nanotechnology (Nanotechnology)", which is based on the latest nano-materials, as well as having a lot of attention in the industry, and its development results are appearing slowly. Areas already have successful commercialization in developed countries, but can not yet say that the initial growth stage. Jyeoteuna Japan made a large investment in nano-materials and processes in the 80s, while the present is more focused on nano-devices shoe racks aimed at the development of the electronics shoe racks industry situation in the United States and Europe, with a focus on the establishment of the underlying technology. So what is nanotechnology? Let's first find the concept of nano. Nano (Nano) is small, and this means that the term is derived from 10-9m (m) of the meaning of ancient Greece as a unit expressing dwarf 'nanos'. If when we expand the baseball to the Earth-sized shoe racks atoms are noticeable about the size of a cluster of grapes. Clube Esportivo Nova Esperança amendment enters into the atoms of side by side to nanometers. Nanotechnology (Nanotechnology) is a broad field of study that has small objects have been dealing with. These include atoms, molecules, ribosomes and the like are the subject of the molecular machinery that produces the protein. When used in a more narrow shoe racks sense, common molecular formula (molecular manufacturing) means to simply say the object at a time (one or molecule) refers to an atom by the way how to array (1) atoms of pencil lead in childhood science class Reorganizing remember everyone by surprise when he found out that the ability to create a diamond. Also, the fact that the semiconductor is obtained by rearranging the atoms of sand Now common sense leads to too obsolete. Recently, the curiosity of a TV program broadcasting shoe racks heaven there are cases of an experiment shoe racks to create a semiconductor material from the sand. Nanotechnology is a field of a combination of several shoe racks disciplines by default. An alternative concept would be to create a device is substantially what is possible and impossible to measure whether physics, mechanical engineering principles is needed, shoe racks but a very large role in the chemical field, especially when it comes to determining the molecular structure was started in biology. (2) surgery to treat the disease at the molecular level, shoe racks smaller computers shoe racks than human cells, and imagine that the second maximum efficiency of production equipment to reduce the size of microscopic contamination. These are the next level of the product molecule or atom further engineering science that is mixed in the future to combine in order to produce a chemical, the goal of nanotechnology. Organizations ranging from the National Science Foundation and NASA, IBM and Lucent Technology Corporation today are uniformly intensively studied the possibilities of nanotechnology. Diamond can theoretically shoe racks produce the carbon atom to relocate. The problem is to create a very small tool that can be moved accurately atoms. And to produce a still more small parts scientists develop extremely small building blocks called buckyballs and nanotubes. Buckyballs (buckyball) is an architect and is named after the name of the engineer R. Buckminister Fuller. Buckyball molecule consisting of 60 carbon shoe racks atoms ultrafine size of a soccer ball shape can be used to make all kinds of things ranging from plastic battery. When ever was a tube-shaped nanometer more than 100 times stronger shoe racks than steel but weighs six times lighter than steel. Nanotechnology researchers have thought it would be to write a nanotube with connectors and cables from the next generation of micro-electronics. Nanotechnologists are thought to be the day used to produce the building blocks of carbon cheaply and in large quantities all diamonds. And the future is dreaming to make a very small device that can be used to help produce other larger devices. Such as technical growth of nanomaterials will take place very quickly, possibly shoe racks applied to a variety of new materials shoe racks and technologies related to the environment is very high. Therefore salpigo information on nanomaterial technology field called dreams by looking at the major achievements of the developed countries in order to future-oriented research should investigate to gauge the current state of the perfume when domestic shoe racks technology. 2. The carbon nano-tube (3) 2-1. Structure of the carbon nanotube is a carbon graphite and familiar with mankind for many years to jinaeon substance exists in two crystal forms of the diamond on the planet. 1985 with a soccer ball-shaped carbon molecules C60 (carbon atoms that gathered 60 dogs: fullerenes) in many laboratories around the world have been found since the first studies to synthesize the carbon of the new structure was conducted. Figure 1. fullerene (C60) Nippon Electric Company (NEC) of the R & D Center, Dr. Nobody was confirmed by electron microscopy that the carbon structure formed by chance daerong elongated shape in 1991, was devoted to these studies of this fact Worldwide were reported in the science journal Nature, this was the beginning of a carbon shoe racks nanotube.
Round ball shaped carbon structure of the (a, b, c) - the fullerene-CNT shoe racks structure and (d, e). The single carbon atom in the carbon nanotubes are combined with three other carbon atoms and form a hexagonal honeycomb pattern. If after such a honeycomb pattern drawn on a flat paper round the paper becomes malmyeon shoe racks nanotube structure. That is one nanotube has a shape such as a hollow tube or cylinder. Why call it because the nanotubes are extremely small enough (a billionth of a meter) in diameter of the tube usually one nanometer. Carbon nanotubes according to a honeycomb pattern and the rounded malmyeon nanotubes are on paper in this case will the end of the paper is also the angle which the electrical conductor such as metal (Armchair structure), and also a semiconductor (Zigzag structure). In addition, according to the unit weight of dried form wall nanotubes (Single-wall Nanotube), multi-wall nanotubes (Multi-wall Nanotube), also separated by a bundle-type nanotube (Rope Nanotube). Figure 3 is subjected to be an impurity-doped (doping) shoe racks is a kind of process, such as carbon nanotubes while carbon nanotubes can be a dog but that it is already known in the semiconductor is now the most widely used silicon to Used as the semiconductor element. Can not do nearly pure semiconductor is going through shoe racks the electric boron (boron), the (phosphorus) to create such a small amount of impurities purposely added to p- type, or of the n- type semiconductor, and this process is called doping. However, carbon shoe racks nanotubes having the same characteristics as wateuna is thought to be extremely difficult to dope a semiconductor hard this application as well, but the carbon nanotube through the electric conductor when the release alone doped semiconductor stack the tube bundle to the fact that many was found. 2-2. Growth of carbon nanotubes of the carbon nanotube synthesis shoe racks is initially mainly been used for an electric discharge method is the study of the current number of ways have been actively attempted. Typical synthetic method of carbon shoe racks nanotubes as an electrical discharge shoe racks method, laser evaporation method, thermal decomposition deposition, shoe racks thermal chemical vapor deposition growth method, a plasma chemical vapor deposition, and the like. Wall Nanotubes Carbon nanotubes unit weight according to the presence or absence and type of transition metal used in the synthesis (Single-wall shoe racks Nanotube), multi-wall nanotubes (Multi-wall Nanotube), is divided into a bundle-type nanotube (Rope Nanotube) synthesis shoe racks The. Without the transition metal in the electric discharge method as the example is a multi-walled carbon nanotube synthesis, the use of transition shoe racks metal-walled carbon nanotube, the unit weight and unit weight synthetic chemical vapor deposition, the thus-walled carbon nanotube, the type of the transition metal and a multi-walled carbon nanotube is synthesized. 2-3. The history of the application of carbon nanotubes, carbon nanotubes are relatively shoe racks short, but recent research is ongoing active areas in the world is important enough to be selected as a teenager in 1997, the world's scientific research. This is because the carbon nanotubes provide different physical properties, and the memory shoe racks element with that, the electronic elements and the like, and provides unlimited shoe racks applicability. Carbon nanotubes are currently seen as a global development trend, the source of science and technology to be used in high-tech electronic information industry that can create high-value-added in the future. Thus, the new technological revolution research areas that are expected to bring a huge ripple effect shoe racks of using carbon nanotubes in the world. (1) FED applications 2000s by state-of-the-art electronics, information age, the coming advent display devices are being far closer to reality virtually represented a new concept shoe racks of display, a CRT display, which led to the current market for flat panel displays in a variety of areas, The replacement shoe racks is expected shoe racks to be a new market for a flat panel display by forming the main shaft. shoe racks Flat panel display to be in the limelight of the CRT is then followed by LCD, LED, PDP, FED, EL, etc., but is currently being discussed Among the high-quality, high-efficiency, FED to the advantage of low power consumption (Field Emission Display) is the next generation of information display devices is greatly in the spotlight. (2) the secondary cell electrode and fuel cell applications carbon shoe racks nanotubes can be obtained even if the number of expected effects applied to a secondary battery electrode and a fuel cell. The most important problem in the secondary battery is to increase the charging efficiency as reducing the weight of the battery. Applying shoe racks the hydrogen alloy currently used instead of the carbon shoe racks nanotubes above two
