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 or molecules. The advent of nanotechnology signifies that human cognition is now at the atomic level and molecular level, which 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 the combination of modern science and technology (microelectronics and computer technology) (including molecular biochemistry, quantum mechanics and high-resolution microscopes and thermal analysis). 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 a symbol of millimeter-based technology. It allowed mankind to enter an industrial era where machinery replaced manpower. The micron-technology applications of the second industrial Revolution in the 20th Century, which was represented by the microelectronics industry, 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 micron-era microelectronics was a major factor in human development. The nano-era nanoelectronics, on the other hand, is the future, because the electronic devices are now smaller and more positive. 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.
One-dimensional. Refers to two-dimensional space at the scale of nanometers.
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 an unprecedented technological 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 a wide range of 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.
