What is nanotechnology?
Nanotechnology is a scientific, theoretical and engineering discipline associated with technological constructs whose dimensions are measured in nanometers or billions of meters. An example would be a study and application of carbon nanotubes, a small carbon tube of several nanometers (approximately 1/50 000. Human hair width) long, with lengths from several dozens of nanometers to several millimeters. Carbon nanotubes are the strongest and strictest materials discovered on the ground, 500 times thicker and ten times lighter than steel.
In order to appreciate the value of nanotechnology, we must realize that virtually all technologies in the history of civilization were built in the utter ignorance of its nanoscopic properties. However, these properties have a huge impact on the mass properties of the material in the macrozice. For example, modern metal armor has general trillions of small nanoparticles and deformations in them because of the thpi production process. Aggregate, these small holes significantly reduce the power of the material, which makes it easiere penetration with a bullet or explosion. If armor was made with the accuracy of nanoparticles, it could be more efficient several times. The study of such properties falls into the domain of nanotechnology.
In addition to working on how to amplify mass materials or more useful, nanotechnology also focuses on small machines or structures. For example, transistors on the computer you are using are probably less than 50 nanometers apart, designed to maximize their available space. In the near future, the designs of circuits begin to push against the limits of miniaturization using contemporary paradigm and force the transition to some other approach. Nanotechnology scientists are studying exactly this and billions of dolls are poured into a field every year.
The final goal of nanotechnology is to accurately control the structure of matter. With the final nanotechnological production equipment can be converted to dirt into fine steaks afterNetwork of nanoparticles that adjust carbon molecules in a suitable pattern. Atoms in both are the same - a lot of carbon - only their arrangement is different. Advanced nanotechnology could allow us to construct the medical means of nanoparticles that swim with our arteries, remove plaque and repair tissue damage. Such machines could one day allow us to live indefinitely, simply by repairing damage caused by aging before they have a chance to accumulate and become fatal.
