What Do Nanotechnology Companies Do?

Nanotechnology is a high-tech that has appeared in recent years. "Nano" mainly refers to substances in the vicinity of the nanometer (a unit of measurement of length, equal to 1 / 1000,000,000 meters). The special properties exhibited are used in different fields and are called "nanotechnology". Its specific definition See entry "Nanotechnology".

Application of nanotechnology

Nanometer is just a unit of length. One micrometer is one thousandth of a millimeter, and one nanometer is equal to one thousandth of a micrometer, which is equivalent to one hundred thousandth of a hair. It has no technical attributes. Therefore, a simple nanomaterial cannot be called nanotechnology without a special structure and performance. Nanotechnology refers to the realization of the arrangement of atoms / molecules on the surface of nanoparticles through a specific technology design, so that it produces a special structure and exhibits specific technical properties or functions. Such nanomaterials can be referred to as nanotechnology.

Nanomaterials can be divided into two levels: nano-ultrafine particles and nano-solid materials. Nano ultrafine particles refer to ultrafine particles with a particle size of 1-100 nm, and nanosolids refer to solid materials made of nano ultrafine particles. And people are accustomed to control the composition or grain structure of the length dimension below 100 nanometers is called nanomaterials.

The continuous improvement of science and technology level, especially in the rising industry of the electronics industry, nanotechnology has been greatly developed, mainly focused on electronic composite films, using ultrafine particles to improve the electrical, magnetic and magneto-optical properties of the film, There are also magnetic recordings, nano-sensitive materials, and more. With the improvement of people's living standards, people's emphasis on environmental protection continues to increase. Air quality and industrial wastewater treatment have become a symbol of quality of life in cities. Due to its unique surface adsorption characteristics, nanomaterials have great development prospects in the purification of air and industrial wastewater treatment.

Nanomaterials are new materials developed in the mid-1980s, which are 50 years ahead of negative oxygen ions. Due to the unique structural state of nanoparticles (1-100nm), it has produced small size effects, quantum size effects, surface effects, macro quantum tunnel effects, etc., so that nanomaterials exhibit light, electricity, heat, magnetism, absorption, reflection Special functions such as adsorption, catalysis and biological activity. Nanomaterials have many unique functions, and the amount is small, but they give the materials unexpected high performance and high added value. Nano-composite polymer materials, nano-antibacterial, fresh-keeping, deodorizing materials, etc., due to the small size of nano-materials, more than a thousand times smaller than red blood cells in the blood, dozens of times smaller than bacteria, and the diffusion rate of gases through them is faster than conventional The material is several thousand times faster. Nanoparticles have a strong effect on the chemical compounds of biological cell membranes and easily enter cells.

The National Institute of Nanotechnology and Engineering is a national-level nanometer scientific research institution with CNAS, CMA, and CAL qualifications, more than 400 highly sophisticated detection instruments and equipment, and a strong team of scientific researchers with doctoral, master, and external experts. Major breakthroughs have been made in optical fiber biosensors, dye-sensitized batteries, solubilization of poorly soluble products, and precision classification technologies.

Nanotechnology application clothing

Adding nano particles to textile and chemical fiber products can deodorize and sterilize. Although the chemical fiber cloth is sturdy, it has annoying static electricity phenomenon. Adding a small amount of metal nanoparticles can eliminate the static electricity phenomenon.

Nanotechnology applications

Using nanomaterials, refrigerators can be antibacterial. Nano-based sterile tableware and sterile food packaging supplies have been available. The use of nano-powder can completely change the wastewater into clean water and fully meet drinking standards. Nano foods are full of color and fragrance, and they are also good for health.

Application of nanotechnology

The application of nanotechnology can improve the scrub resistance of wall coatings by 10 times. The surface of glass and tile is coated with a nano-thin layer to make self-cleaning glass and self-cleaning tiles without scrubbing at all. Building materials containing nanoparticles can also absorb ultraviolet rays that are harmful to the human body.

Nanotechnology Application

Nanomaterials can improve and improve the performance indicators of vehicles. Nano-ceramics are expected to become ideal materials for engine parts such as automobiles, ships, and aircraft, which can greatly improve engine efficiency, working life and reliability. Nano satellites can provide drivers with traffic information at any time to help them drive safely.

Nanotechnology Applied Medicine

The mini-medicine conveyor made by nanotechnology can carry a certain dose of medicine, and accurately reach the lesion site under the guidance of external electromagnetic signals, effectively playing a therapeutic role and reducing the adverse reaction of the medicine. The nano-made micro-robot has a volume smaller than that of red blood cells. By injecting into a patient's blood vessel, it can clear the blood clots in the cerebral blood vessels. Removes fat and sediment from the arteries of the heart, and "chews" urinary stones. Nanotechnology will be a good helper for a healthy life.

The application prospects of nanotechnology are very broad, and the economic benefits are huge. The authoritative organizations in the United States predict that the nanotechnology market in 2010 is estimated to reach $ 1.44 billion, and the future applications of nanotechnology will far exceed the computer industry. The modification of nanocomposite, plastic, rubber and fiber, and the design and application of nano-functional coating materials will inject new high-tech content into traditional production and products. Experts point out that in the fields of textiles, building materials, chemicals, petroleum, automobiles, military equipment, and communications equipment, there will inevitably be a "material revolution" caused by nanometers. There are now nearly 100 companies registered in nanomaterials and nanotechnology in China. Established more than 10 nanomaterials and nanotechnology production lines. Nano fabrics and clothing have been mass-produced, and nano-clothes such as computer workwear, non-static clothing, and UV-proof clothing have come out. The new paint with nanotechnology not only improves the washing resistance by more than ten times, but also is non-toxic, harmless and odorless. Nanotechnology is improving and improving people's quality of life.

At present, many countries have formulated related plans and invested huge sums to seize the strategic high ground of nanotechnology. The emergence of each new technology seems to contain infinite possibilities, especially the nano robot has promising application prospects. It won't be long before magical nano-robots the size of a molecule will continue to enter human daily life. In the article "On Robots" published by a famous Chinese scholar, Professor Zhou Haizhong in 1990, he predicted that by the middle of the 21st century, nano-robots will completely change human labor and lifestyle.
