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. 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.
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.

What is the nanotechnology around us?
1. Some clothes are filled with metal nanoparticles, which will not generate static electricity. 2. Some refrigerators use nano-coating, which can effectively sterilize and deodorize. 3. There are also some socks products added with nano-materials, which can sterilize and deodorize. The relationship between work and life is complementary. Work can provide guarantee for life, and a better life is the purpose of work. If people don't work, life is not only insecure, but also mediocre, losing value and fun. But if you only work, you have no time to enjoy life. This experience is unpleasant. The word "workaholic" is familiar to everyone, and it is a brand-new word in my impression. Refers to people who are extremely involved in their work and are almost crazy. Such people probably can't "live" or can't talk about "life". In fact, such people have existed for a long time, and of course they are everywhere, but they have never used this word. It seems that everyone who can be called a great man is a person who forgets his work. Let's call this kind of people for the time being: people who work first and live second. Even people who only have jobs in their lives. Then there is the so-called pursuit of the ultimate life. They are not necessarily very rich or enthusiastic about their work. It's just that they think that work is simple and simple, and living in their world is never allowed to be called "days". It should be said that such people live a very chic and comfortable life, which is the meaning of their life. This kind of person is: life first, work second. There is another kind of person who is the most ideal and has a large number. That is to strictly separate work from life. Work is work, and life is life. "Distinguishing between public and private" is their principle and wish, and they are never confused. They think that work and life are equally important. Work is their need, and life is their pursuit. I also want to talk about such people, whose life is undoubtedly the highest purpose of their life. In fact, they have no concept of life at all. They just have the logic that work is for life, or work is for a better life, and they can't live without work. At this time, the concept of life seems to be just "living" or "survival". Actually, it's not. It is a kind of consciousness. I think there is such a consciousness in our tradition, and the thinking of all people or the vast majority of people is limited by this logic. Of course, we can't forget such a group of people. They are a group of happy people. In their world, work and life are all arts. They never consider whether they live to work or work to live. Every day, they enjoy it. There are all kinds of people, some of whom we can't describe vividly. Life is the whole process of a person's life, and work is only a part of life. Like many aspects of life, without work, it is incomplete and incomplete. Finally, I can understand why some people temporarily give up another part of their lives for work. Life is not just living, living is the foundation of life. Only by living can we really live. Mastering the relationship between work and life is conducive to our physical and mental pleasure and growth.
