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 and arranging molecules and atoms. The advent of nanotechnology signifies that human cognition is now at the atomic level and molecule level, and marks a new age of science and technology.The science and technology of nanotechnology is a blend of many advanced modern sciences and technologies. It is the combination of modern technology and science (microelectronics and computer technology) as well as modern science (quantum biology, molecular 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. The microelectronics of the 20th Century was the symbol of the second industrial Revolution, which enabled mankind to enter a time of computers and communications networks. 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 nanotechnology age is characterized by the future of nanoelectronics, due to the decrease in the strength of electronic devices, even down to single molecules and nanometers. 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. 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. 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, in ultra-thin films, multilayer films and superlattices.

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