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 create new materials by manipulating atoms and molecular structures. It is the beginning of a new age of science and technology, the nanotechnology era.The science and technology of nanotechnology is a blend of many advanced modern sciences and technologies. It is the combination of modern science and technology (microelectronics and computer technology) (such as quantum mechanics and molecular biochemistry). 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 industrial 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 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
Nanomaterials form the basis of the development of the nanotechnology industry and are the primary research object for nanotechnology. The dimensions of the nanomaterials that we use can be divided into 3 categories:
-
Zero dimension. The nanometer scale refers to three-dimensional space dimensions. For example, nanoscale particles and clusters.
-
One-dimensional. Two-dimensional.
-
Two-dimensional. This means that the one dimension in three-dimensional spaces is at nanometer scale, for example, in ultra-thin films or superlattices.

The new understanding that nanotechnology brings to the material world is a catalyst for a technology revolution. Nanotechnology has given us initial demonstrations of new materials and energy, computer technologies, biomedical, and aerospace applications. Nanotechnology, however, is not an island. 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.
