What are the nanotechnologies around us?

There are many examples of nanotechnology around us, such as nano clothes, nano socks, nano washing machines that have appeared on the market, as well as nano air conditioners and nano sterile tableware that can remove odors, antibacterial nano gauze, etc.

Industrial applications of nanotechnology: In the glass manufacturing industry, nanotechnology can be used to make dust-resistant and non-conductive glass, so-called "reactive glass" or "self-cleaning glass", which is able to self-clean using dust and water droplets. It is also used to create three-dimensional screens with high transparency and flexibility.

In the sporting goods industry, it can be used to make lighter, more flexible and stronger sports products, such as tennis and hockey rackets. In the new materials industry, it can be used to produce materials that are lighter than steel and not inferior in hardness to steel.

Nanotechnology for agricultural applications: Nanotechnology can be used to improve agricultural production techniques, so that crops can withstand harsh environments, and can promote better absorption of nutrients by plants, as well as detect and control the growth process of plants in real time.

Nanotechnology application in the new energy industry: Nanotechnology can be used to make batteries that can store a large amount of energy for a long time, so the production cost of new energy vehicles will be lower, and it can not rely on traditional oil.

Nanotechnology applications in medicine: Scientists have been able to create precise instruments for the size of bleeding cells, which can lead to many diseases that require surgery, such as blockages in arteries. It is also possible to detect some diseases in the human body in real time through nano-level sensors.

For example, Italian researchers have also invented an "electronic nose" using carbon nanotubes, which can diagnose cancer by analyzing the air exhaled from the lungs by the human body. In addition, it can also be used for **tumor diseases, such as gold-plated nanoparticles can be used to destroy cancer cells.

What nanotechnology is around us.

1. Adding nanoparticles to textile and chemical fiber products can remove odor and sterilize. Although the chemical fiber cloth is strong, it has an annoying static electricity phenomenon, and a small amount of metal nanoparticles can be added to eliminate the static electricity phenomenon.

2. The use of nanomaterials and refrigerators can be antibacterial. Sterile tableware and aseptic food packaging supplies made of nanomaterials have been launched. The use of nano powder can make the wastewater completely clean and fully meet the drinking standard. Nano food is full of color, flavor and taste, and it is also good for health.

3. The application of nanotechnology can increase the scrubbing resistance of wall paint by 10 times. The surface of the glass and ceramic tile is coated with a nano thin layer, which can be made into 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.

4. 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. Nanosatellites can provide traffic information to drivers at any time.

Nowadays, scientific and technological progress is advancing with each passing day. Many people already have some understanding of high-tech such as "Internet" and "genes". In recent years, new terms such as "nano", "nanotechnology" and "nanomaterials" have become louder and louder.

For many teenagers, the term "nano" seems unfamiliar, and nanotechnology is even more magical and incomprehensible. In fact, nanotechnology has long been quietly integrated into our lives.

A nanometer is a unit of length, and one nanometer is equal to one billionth of a meter, which is really small. How small is it? To use an analogy:

Make a red plastic ball with a diameter of one nanometer (of course, invisible to the naked eye) and place it on a ping-pong ball as if you were putting a ping-pong ball on the earth. Electron microscopy is required to observe the shape and topography of nanomaterials.

The so-called "nanomaterials" and "nanotechnology", simply put, are some ordinary materials made into nano to hundreds of nanometers of particle materials, which are extremely small in size, but have a large surface area and special structure, which will produce a kind of magic and special properties, and apply them. Scientists have summarized the special properties of nanomaterials into four major effects: small size effect, surface effect, interface effect, and macroscopic quantum tunneling effect.

Examples of nanomaterial applications can be cited to many. For example, chemical fiber clothes often produce annoying static electricity when worn on the body. A small inconspicuous electrostatic spark can cause ** and fire on some special occasions.

If a small amount of metal nanoparticles is added to the chemical fiber cloth in the production of chemical fiber fabrics, then the frictional electricity generation phenomenon will no longer occur in the chemical fiber fabrics. Another example is adding some nanoparticles to textiles such as socks, which can deodorize and sterilize. At present, nano washing machines, air conditioners and sterile tableware that can remove odors, antibacterial gauze, etc., have appeared on the market, and nanomaterials are used in these products.

Scientists pointed out that nanotechnology is the common basis for the further development of information and life science technology, a key point in the future development of science and technology, a technological revolution, and will also give rise to another industrial revolution in the 21 st century, which will have a huge and far-reaching impact on human society.

Chemical fiber clothes will produce a lot of static electricity and sparks, and sometimes there will be ** and fire, if you add a small amount of metal nanoparticles, you can avoid such a thing.

There is nanotechnology around us, there are nano washing machines, nano vacuum cleaners, nano cars, nano clothes.

: Such as carbon nanotubes, carbon nanotube ladders, ......

Health is the most important topic for people in the 21st century. SOMO is committed to innovating in the food and pharmaceutical fields by leveraging its technological strengths. A series of health care foods have a significant effect on regulating human body functions, while personal care products are mainly used externally, and their bioavailability is greatly improved by nano-active ingredients, resulting in significant results.

A short video tells you what nanotechnology is.

What nanotechnology is around us.

1. Some clothes add metal nanoparticles to them, so that static electricity will not be generated. 2. Some refrigerators use nano coating, which can effectively sterilize and deodorize. 3. There are also some socks with nanomaterials added to them, which can sterilize and deodorize.

The relationship between work and life is complementary, work can provide security for life, and a better life is the purpose of work. If people don't work, their lives will not only be insecure, but they will also be inactive, losing their value and enjoyment. But if you only work, you don't have time to enjoy life, and such an experience is unpleasant.

Workaholic"This word is not unfamiliar to everyone, and I have the impression that this is a very new word produced in contemporary times. It refers to a person who is extremely devoted to his work, bordering on madness, and probably not"life"Or don't talk about it"life"Target.

In fact, such people have existed for a long time, and of course they have spread all over the country, but they have never used the word. It seems that every great person is a selfless worker. For the time being, let's talk about this kind of person as: work first.

1. People who live second. Even people who only have a job in their lives.

Then there is the so-called pursuit of the ultimate life, they are not necessarily very rich, and they also have a passion for work. It's just that they think that work is simple and simple, and in their world there is no room for life to be said to be"days"。It should be said that such people live an extremely chic and comfortable life, and the meaning of their lives lies in this.

This kind of person counts: life.

1. People who work second.

There is also a type of people who are the most ideal and have a lot of them. That is to strictly separate work and life, work is work, and life is life. "There is a clear distinction between public and private"It is their principles and aspirations that are never mixed up.

They believe that work and life are equally important, work is their need, and life is their pursuit.

I also want to talk about such a kind of people, life is undoubtedly the highest purpose of their life, in fact, they have no concept of life in their hearts, they just have this logic: work is to live, or rather, work is to live a better life, and you can't live without work.

The concept of life at this time seems to be just"Alive"or"Survival"。Actually, it's not, it's a kind of consciousness. I think that 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.

We certainly can't forget such a group of people, they are a happy people. In their world, work and life are artistic. They never think about the question of whether they live to work or work to live. Every day of their lives, it's all about enjoyment.

There are also many kinds of people, some of whom we cannot describe vividly.

Life is the whole process of a person's life, and work is only a part of life. As in many aspects of life, without work, there is no incompleteness. Finally, it is understandable why some people temporarily give up another part of their life for the sake of work, life is not just living, but living is the foundation of life, and only by living can it be regarded as truly living.

Mastering the relationship between work and life is conducive to our physical and mental happiness and growth.

1. Clothing - traditional clothes generally meet people's functions such as keeping out the cold, covering shame and heat dissipation, while the functions of clothes with nanomaterials will be completely different: adding nano-level ultraviolet reflectors (titanium dioxide, zinc oxide, aluminum, carbon black) and improving the quality of the textile itself can make anti-ultraviolet fibers. The addition of contact antimicrobial agents, such as metal elements, metal ions, and photocatalysts, such as nano titanium dioxide, nano zinc oxide, and nano silicon oxide, can be added to textile fabrics to create antibacterial, antibacterial, and deodorant chemical fiber fabrics.

2. Food - nanomaterials also play a unique role in diet, compared with traditional ingredients and kitchenware, it has a huge advantage: the use of nanotechnology to reprogram food molecules, atoms will change, so that the absorption rate of some components can be greatly improved, the transportation of nutrients in the body, and the shelf life of food can be extended. Nano food has the functions of improving nutrition, enhancing physical fitness, preventing diseases, restoring health, regulating body rhythms, and delaying aging.

At present, nano foods mainly include calcium, selenium and other mineral preparations, vitamin preparations, calcium milk and soybean milk with added nutrients, nano tea and various nano functional foods.

3. Housing - nanomaterials are widely used in building materials and decoration coatings, which can significantly improve people's accommodation level. The addition of nano ferric oxide, nano titanium dioxide and nano zinc oxide to the coating can improve the brush resistance of the wall coating by nearly ten times and make the coating have a certain self-cleaning ability.

The surface of glass and tiles is coated with a layer of nano film, which can be made into self-cleaning glass and self-cleaning tiles, and there is no need to wipe them at all.

3. Lines - Nanomaterials can improve and improve the performance indicators of vehicles. The amount of plastic used in automotive manufacturing will increase. Reinforced plastics are filled with surface treated nano-scale inorganic materials montmorillonite, calcium carbonate, silica, etc., which have obvious astringent effect on the molecular crystallization of polypropylene, which can increase the tensile strength, impact toughness and elastic modulus of polypropylene and other plastics, so that the physical properties of plastics can be significantly improved.

Clothing, home appliances, daily necessities, clothing using nanotechnology can improve the performance of fabrics, such as waterproof, warm, breathable performance is better than ordinary fabrics. The use of nanotechnology in integrated circuits in household appliances will reduce the product's performance, reduce the size of the product and make it easy to carry. Detergents in daily necessities using nanotechnology will improve the ability to remove stains, and so on.

Nanotechnology can make people healthier, and cancer is scary, but if it can be detected when there are only a few cancer cells, the mortality rate will be greatly reduced. Cancer cells can be killed by blood vessels directly to the lesion.
