Nanotechnology-Human new technological revolution
It is a new high-tech which emerged in late 1980s. Its main purpose is to analyze the composition and structure of nanometer-sized matter and to produce new substances through direct manipulation and arrangement of atoms and molecular. The advent of nanotechnology signifies that human cognition is now at the molecular and atomic level. This marks a new age of science and technology.The science and technology of nanotechnology is based on a number of advanced modern sciences and technologies. It is a combination between modern science and technology (microelectronics (computer technology), high-resolution microscopes (thermal analysis), and quantum mechanics). Product. Nanotechnology has penetrated into various fields of modern science and technology, and has formed many new researches related to nanotechnology, such as nanophysics, nanochemistry, nanomaterials, nanobiology,nanoelectronics, nanofabrication, and nanomechanics. All these constitute nanotechnology.
In the middle 18th century the steam engine was the symbol for the first industrial Revolution, which allowed mankind to enter an era where machinery replaced manpower. In the 20th Century, microelectronics represented the second industrial Revolution, which was a hallmark of micron technologies. It enabled mankind to enter a time of computer networks and communications. In the 21st century, it is expected that nanotechnology and emerging science will lead to a new industrial revolution.
The nanotechnology revolution will change our understanding of the world. As an example of electronic technology, the microelectronics of today has been a major factor in human development. However, the nanoelectronics of tomorrow will be based on the fact that electronic devices are now only positive in nanometers, and sometimes even in single molecules. Electronic technology will play a major role in the future.
Nanomaterials form the basis of the development of the nanotechnology industry and are the primary research object for nanotechnology. Nanomaterials can be classified according to their dimensions into three basic categories:
Zero dimension. The nanometer scale refers to three-dimensional space dimensions. For example, nanoscale particles and clusters.
Two-dimensional. This means that the one dimension in three-dimensional spaces is at nanometer scale, for example, ultra-thin films, multilayer films and superlattices.

The new understanding that nanotechnology brings to the material world is causing a technology revolution. Nanotechnology has given us initial demonstrations of new materials and energy, computer technologies, biomedical, and aerospace applications. Nanotechnology, however, is not a solitary field. It involves many different disciplines including quantum mechanics, materials sciences, colloidal and physical chemistry as well as polymer and biochemistry. We can understand and master nanotechnology better by integrating disciplines.
