Nanometer is a unit of length, and one nanometer is equal to one billionth of a meter, which is really too small. How small is it? For example, make a red plastic ball with a diameter of one nanometer (invisible to the naked eye, of course) and put it on table tennis, just like putting table tennis on the earth. It is necessary to observe the shape and morphology of nano-materials with electron microscope.
The so-called "nano-materials" and "nano-technology" simply mean that some ordinary materials are made into granular materials with the size of 0. 1 nm to hundreds of nanometers. Its particle size is extremely small, but its surface area is large and its structure is special, which will produce a magical and special performance and be applied. Scientists summarize the special properties of nanomaterials into four major effects: small size effect, surface effect, interface effect and macro quantum tunneling effect.
There are many examples of the application of nanomaterials. For example, chemical fiber clothes often produce annoying static electricity when worn on the body. Tiny and unremarkable electrostatic sparks can cause explosions and fires in some special occasions. If a small amount of metal nanoparticles are added when making chemical fiber cloth, the phenomenon of triboelectricity will not happen again. For example, adding some nanoparticles to textiles such as socks can deodorize and sterilize. At present, nano washing machines, air conditioners, sterile tableware and antibacterial gauze that can deodorize have appeared on the market, and these products all use nano materials.
Scientists point out that nanotechnology is the same foundation for the further development of information and life science and technology, a key point for the future development of science and technology, a technological revolution and another industrial revolution in the 2/kloc-0 century, which will have a great and far-reaching impact on human society.

Is the double eyelid cut completely or not? _ A pair of eyes saves a face _ Contrast before and after double eyelids
People who pay attention to double eyelids are also watching.
Whether the double eyelids are completely cut is better. According to the proportion of eyes and face before operation, the marks are measured in three stages, and microsurgical tools are used, which has less skin trauma and less postoperative swelling. We have many years of experience in microsurgery. Click to view double eyelids immediately after the operation.

AKA consulted an educational question and published it, so that the manufactured chemical fiber cloth would not have triboelectric phenomenon again. For example, adding some nanoparticles to textiles such as socks can deodorize and sterilize. At present, nano washing machines, air conditioners, sterile tableware and antibacterial gauze that can deodorize have appeared on the market, and these products all use nano materials. Nowadays, scientific and technological progress is changing with each passing day. Many people already know about high technologies such as "Internet" and "gene". In recent years, new terms such as "nano", "nano-technology" and "nano-material" are getting louder and louder in people's ears. For many teenagers, the term "nano" seems strange, and nanotechnology is even more mysterious and difficult to understand. In fact, nanotechnology has already been quietly integrated into our lives.
