Now the so-called so much what nano nano, basically are advertisements, at present I can tell you, not many things really need that nanotechnology, at present there are only a few types of things really used
Chips, especially processor chips, such as your computer that, this is really used in nanotechnology
see Now INTEL and AMD processors, 65 nanometer process, 45 nanometer process, already in the nanometer scale, they are by changing the position of the silicon atoms, to cut the silicon chip, the manufacture of circuitry, so this is nanotechnology
And the other what light bulbs, refrigerators, TVs say what nanometer, simply is the advertisement blowing, a little bit of significance, because at all, in those places there is no need for nanotechnology, so it's a good thing that the processor chip is not a nanometer. On, in those places simply do not need what nanotechnology.

Reports about the technical application of nanometer
Nanometer material technology in the application of automobile The development of automobile technology depends on the development of material technology, and now the popularity of the world's nanotechnology in the application of automobiles, for the development of new material technology to lay the foundation. Nano is a unit of measurement, 1 nanometer is one millionth of a millimeter. Such a tiny space is actually the basic unit of matter, the space of atoms and molecules. Since the invention of the electron scanning tunneling microscope in the early 1980s, the world has witnessed the birth of nanoscience, the study of the microscopic world in nanometers. The technology of studying and processing substances in tiny structures of less than 100 nanometers is called nanotechnology. In the 1990s, nanoscience has developed rapidly, resulting in nanomaterials, nanochemicals, nanomechanics, nanobiology and so on, and the resulting nanotechnology products are also endless, and began to involve the automotive industry. So what is automotive nanotechnology? Experts predict that nanometer interface material technology, namely super amphiphilic binary synergistic interface material technology (hydrophilic and lipophilic) and super double hydrophobic interface material technology (hydrophobic and oleophobic), can be realized in any material surface. Therefore, if the domestic rubber material applies these two technologies, the problems of oil leakage and oil seepage that plague domestic automobiles will be solved. The number of plastics used in automobile manufacturing will be increasing. Nanoplastics can change the characteristics of traditional plastics, showing excellent physical properties: high strength, heat resistance, smaller specific gravity. Since the size of nanoparticles is smaller than the wavelength of visible light, nanoplastics can show good transparency and high gloss, so nanoplastics will have a wide range of uses in automobiles. After nanotechnology treatment of part of the material wear resistance is 27 times that of brass, steel 7 times, such as nano-ceramic bearings have been used in Mercedes-Benz and other high-grade cars. At present, China has developed a kind of emulsifier made of nanotechnology, with a certain proportion of gasoline, can make a car like Santana reduce fuel consumption by about 10%. What's more interesting is that nanotechnology can save a lot of cost when applied to fuel cells. Because nanomaterials have excellent hydrogen storage capacity at room temperature. According to experimental results, at room temperature and pressure, about 2/3 of the hydrogen energy can be released from these nanomaterials, so they can replace the expensive ultra-low temperature liquid hydrogen storage device. The School of Chemistry and Molecular Sciences at Wuhan University has made a breakthrough in the research of nanoscale titanium dioxide. Using Wuhan University's patented technology to produce nanoscale titanium dioxide, its cost is only about 1/4 of the cost of foreign countries. The introduction of nanoscale titanium dioxide is a new development in the field of titanium dioxide research in the late 1980s. Japanese and U.S. scientists found that the substance can be widely used in high-grade cars, such as metallic paint. Japan has been set up on both sides of highways and tunnels coated with nanoscale titanium dioxide photocatalytic plate to remove nitrogen oxides to prevent car exhaust. At present, only a few companies in the world can produce nanoscale titanium dioxide. It is believed that in the near future, nanotechnology will be more widely used in the field of automobile manufacturing. Nanotechnology in the field of optoelectronics Nanostatic shielding materials, another important application of nanotechnology Nanotechnology in bioengineering

How is nanotechnology caused?
Nanotechnology is based on nanoscience, the study of the nature of materials and their applications in the range of structural scales from 0.1 to 100 nm, the manufacture of new materials, new devices, and the study of new processes and methods. Nanotechnology is based on the microscopic research theories of physics and chemistry, with contemporary precision instruments and advanced analytical techniques as the means, and is a product of the combination of modern science (chaos physics, quantum mechanics, mesoscopic physics, molecular biology) and modern technology (computer technology, microelectronics and scanning tunneling microscope technology, nuclear analytical technology). In 1993, the International Steering Committee for Nanotechnology (ISCN) divided nanotechnology into six sub-disciplines: nanoelectronics, nanophysics, nanochemistry, nanobiology, nanofabrication and nanometrology. Among them, nanophysics and nanochemistry are the theoretical basis of nanotechnology, while nanoelectronics is the most important content of nanotechnology. Nanotechnology is an emerging science and technology that developed rapidly in the early 1990s, and its ultimate goal is for human beings to directly manipulate individual atoms and molecules in accordance with their own consciousness to create products with specific functions. Nanotechnology reveals a visible world of atoms and molecules for us with unprecedented resolution. This shows that human beings are getting deeper and deeper into the microscopic world, and the level of people's understanding and transformation of the microscopic world has been raised to an unprecedented height. Some data show that in 2010, nanotechnology will become the second largest industry after chip manufacturing.

Examples of nanotechnology applications in life
Nanometer applications in life Nanotechnology actually covers all the techniques and technologies of physics and chemistry in the nanometer range, and it is not too much to say that it is all-encompassing. Devices made from nanomaterials are lighter in weight, harder, longer in life, cheaper to maintain, and easier to design. Using nanomaterials it is also possible to make materials with specific properties or materials that do not exist in nature, to make biomaterials and bionic materials. However, nowadays there are a lot of speculative concepts, and many of them are limited to the theoretical stage in the laboratory. The more realistic ones are lubricants in machinery, catalysts in chemical industry, and fixed-point super-effective agents in medicine. Construction The use of nanotechnology in construction can make a big difference in results. Indeed, some nanotechnology applications are already on the market. For example, in environmental projects we see new smart materials mixed with titanium dioxide nanoparticles for self-cleaning windows, buildings and roads. (In Milan, 7,000 square meters of roads have been treated with these materials thus reducing nitrogen dioxide levels by 60%). Other nanomaterials have been added to new construction materials to improve mechanical strength, durability and insulation, while reducing weight compared to traditional materials. For example, nanoceramics are being used in cement to increase strength. Sensor systems are increasingly being used in construction, including monitoring the environment of buildings and the strength of any machinery. Sensor systems Some sensor systems are being used in buildings, similar to those discussed in the Environment section, but the sensing is being used more to test the structural strength of the building, wear and tear, etc., so that people are aware of any safety hazards in the building. When sensors are connected to the heating/air conditioning system to select optimal settings, the data collected from the sensors can be used to provide environmental monitoring and even temperature control of the building. Nanotechnology can also help provide a system-wide view of the "feel of the building" in detail. All sensors and monitoring data are transmitted to a centralized node for processing and implementation. The electronics involved will be smaller, but just as (if not more) powerful. They would use energy more efficiently and could even put in small solar cells, effectively making their own power. As a result, it is possible to make this system maintenance-free and long-lasting. Nano Home Appliances There are many electrical companies have launched novel nano home appliances one after another. The so-called nano-appliances are home appliances produced using nanotechnology. In the nano world, matter has taken a qualitative leap. Such as conductive properties of good copper at the nanometer level does not conduct electricity, and insulating silicon dioxide at the nanometer level began to conduct electricity; Silicon dioxide ceramics are usually very brittle, but when the silicon dioxide ceramics particles narrowed to the nanometer level, brittle ceramics surprisingly have the toughness. When the material is refined to the nanoscale, the nanomaterials created are special in nature and extremely versatile. Nanomaterials were added to airplanes to absorb radar waves, and stealth airplanes were created. Knives made of nanomaterials are harder than diamond knives. Computer chips and CD-ROMs, processed into nanoscale, its computing speed and recording density is higher than the norm by various orders of magnitude. At present, nanotechnology in the field of home appliances is also mainly used for antibacterial, antimicrobial and other "health" aspects. Such as the current market sales of nano-freezers, that is, easy to contact in the hands and bacteria are easy to invade the parts of the use of nanosized materials, this material can effectively inhibit the growth of bacteria, thus improving the antimicrobial capacity of the freezer. Nano washing machine, that is, the outer drum of the washing machine using nanomaterials, so that the washing machine can not only prevent high temperature, wear-resistant, and has a strong anti-scaling ability. It is foreseeable that with the adoption of nanotechnology by more home appliance enterprises, nano home appliances will become popular products in the future market. At the same time, China's major basic research nanomaterials scientists expert group chief expert Zhang Lide researcher clearly pointed out that: "nanotechnology to be like information technology to produce a wide and profound impact, it will be two or three decades later."
