As the founder of the United Nations, Tang Ning did not attend the Constitutional Convention. However, his influence was everywhere. The paper used by all the participants was his latest invention. The emergence of this paper was called the "revolution of paper" by scientists, which shows that it is not an ordinary product.

The raw material of this paper is cellulose, like traditional paper, but it is processed into fiber glue, which looks more like glass and is transparent, so it is called cellophane. The display principle it uses is unique, and the color rendering method is "structural color".

The story starts with a huge and beautiful butterfly in the Americas. The wings of this creature called flashing butterfly can reach 20 cm long after it is developed. This is a butterfly, not a bird, and its wings are charming blue. When it spreads its wings and flies, it is like a stunning blue light flashing in the green ocean of America.

A shrewd engineer was fascinated by the color of this butterfly and thought to himself that if he could extract this blue color as a new pigment, he might make a big profit. He firmly believed that people would fall in love with this new blue pigment.

After the engineer caught the flash butterfly, he started to do scientific research. His experimental plan was as follows: first grind the wings into very fine powder, and then extract the pigments in them with alcohol as a solvent. In his past scientific research career, he successfully identified many pigments using this method. This time, he was naturally full of confidence and believed that he would succeed.

However, this time he was distressed to find that the wings of the flash butterfly disappeared after being ground into powder. Does the grinding process destroy the chemical structure of the pigment? It seems impossible. How big is it to grind into powder? How can a chemical reaction occur?

But he thought it might be that the pigment was quite fragile, so he tried to extract it directly with alcohol without grinding. At this time, a more strange phenomenon occurred. The wings soaked in alcohol turned green! Did alcohol and pigment react chemically?

When he took out the butterfly alcohol, the flash blue returned to its original state. The engineer was puzzled and announced his discovery on the C-B of the Global University of Technology Alliance, which sparked heated discussions.

Tang Ning noticed this big discussion, and he was not involved, but on a whim the idea of ​​using this way of color production. This color does not require special chemical raw materials at all, and its appearance is determined by the microstructure of the surface of the flashing butterfly wings.

The wavelength of light determines the color of light, and the preference of matter for the wavelength of light determines the color of matter. For example, red matter absorbs all the colors of orange, yellow, green, blue, purple, etc., so our eyes only see red.

However, the wavelength of light can be changed because light has interference and scattering phenomena. The wings of the butterfly use the interference of light.

The microstructure of the wings of the flashing butterfly can cleverly combine two beams of light into a beam of blue light using the different lengths of distances.

But just one interference light intensity is not enough. This is why we see that the color on the bubbles is very light.

Under the microscope, we can see that the wings of the flashing butterfly have small pieces of scales. The color formed by a large number of phosphorus slices is very eye-catching!

This is the structural color. Most colors will fade over time. This is because the oxygen in the air will react chemically with the color.

However, there is no problem with the color composed of structural colors. If the Terracotta Warriors and Horses of Qin Shihuang used structural colors, then it would never change color.

Archaeologists will not regret the fading of all the Terracotta Warriors and Horses excavated within an hour.

Artificially creating structural colors requires not only a deep understanding of the reasons for it, but also powerful tools to process the surface of cellophane.

Tangning uses precision lasers to form microstructures on the cellophane surface. This technology is much more complex than at first glance. Just like LEDs, blue LEDs are much more difficult than red LEDs and green LEDs.

Screening out lasers that can be used to make glass microstructure surfaces is a difficult process. Even a team as powerful as the Windsor Technology Empire can only display monochrome, that is, blue, on cellophane.

Moreover, this color is not perfect. When the angle of the observer is relatively small, a rainbow-like effect will appear. It is really good to use it on banknotes, but it is not too serious when used in serious occasions.

Tangning will solve the monochrome problem and the rainbow color problem in the second generation of products. The way to solve the monochrome problem is to learn from the peacock.

The eyes on the peacock's feathers are not only blue, but also green and yellow. In order to achieve this effect, the peacock's feathers are evolving more complex.

Under the microscope, you can see that there is a columnar structure with a diameter of 100 nanometers under the keratin. There are many air channels between them.

The blue feathers contain nine to twelve layers of apertures, and the distance between the apertures is 140 nanometers. If the distance between the apertures increases by ten nanometers, the feathers will turn green.

The yellow feathers contain only about six layers of holes with a spacing of about 165 nanometers. Continuously changing the "configuration", Downing's laser printer can create a colorful world on cellophane. However, this microstructured laser machine is not strong enough in the United Nations Constitutional Convention, because it is all written.

Only in future commercial and entertainment industries, colored microstructures can be used for "peacock-level" laser printers. All colors on cellophane can be reset by the high heat generated by lasers, so cellophane can be used repeatedly. The cost of a piece of cellophane is a little more expensive than ordinary paper, but it can be used repeatedly, so the overall cost is much smaller.

The "peacock-level" microstructure still has rainbow color. If you want to solve this problem, you have to learn from the kingfisher. Its feathers are also structural colors, but there will be no rainbow phenomenon. Because the kingfisher feathers use the principle of dispersion, which is the same as the principle of the sky being blue, we will not see that the blue of the sky will spontaneously turn into a rainbow.

Monochrome blues "flash butterfly level", colorful "peacock level", perfect color "kingfisher level", and three-level microstructure laser printing cellophane technology, one level is more complex and advanced, and all require high-energy ultraviolet laser to be used to handle it.

Most chemical pigments are toxic, and some people are allergic to certain pigments. Now, when our third-level god display technology is mature, humans no longer have to deal with a large number of chemical pigments every day, and from then on, the quality of life will reach a great level.

In the future, there will be no such thing as "the printer has no toner and ink cartridges!", which is a more expensive expense than paper. The printer is also efficient because it no longer needs to be preheated, and the laser is a magic servant on call.

There was always an indelible smell after the newspapers were freshly released. In this way, many people used it to make breakfast. The chemical-free pigment newspaper invented by Downing appeared together with the United Nations Constitutional Convention. The Telegraph took the lead in using it with the selling point of "can be packaged for food".

Indeed, the processing is very simple after the newspaper is recycling. It used to be filtered for pigments, but now it is used to use heat-resistant materials. All dirt can be burned by lasers, just like the cleaning method of the Nanjing Yangtze River Bridge, and then it is put into microstructure printing. Therefore, the recycled newspapers are not only cleaned, but also disinfected at high temperatures, and can be truly used to package food.

The three primary color printing factory invented is the world's largest newspaper printing OEM. They strongly recommend that customers use cheap, non-toxic blue-word printing technology. Because of the high reusability of cellophane, a considerable number of newspapers have achieved the cost of pocket paper, greatly reducing the cost. In the future, more free newspapers that sell advertisements will appear.

Although our shelter houses with billboards are for paupers and homeless people, they are pioneers in using high-tech. The outdoor advertising industry is also destined to be changed by structural color technology, because they no longer have to try their best to brush and brush. The surface of the billboard is covered with a layer of microstructured patterns, and only a laser machine that can move freely is needed.

Water can change the color of microstructure, so you have to add a layer of protective glass to it, which are just small details.

Changing large-format advertising content has never been easier than now. The cost of changing it every day is not high, not to mention changing it during festivals, changing aesthetic fatigue, and changing it even if you are in a bad mood. In the Bund, there are high prices and high traffic flow sections like Wangfujing, which can be changed every day.

This technology that controls two extremes has made the newspapers more environmentally friendly to treat things that were lost on the same day, and on the other hand, the quality of old books and magazines is still quite high, and the Siba is the same as the newly released ones.

In the future, the old books sold by pounds will never be discriminated against again, because after laser cleaning, they are almost the same as new ones, and can almost be sold as new ones, making some criminals cheaper.

This technology cannot be used on displays, because creating microstructures requires high-energy ultraviolet rays, so it is difficult to do this when facing the user's display screen every day.

Tang Ning has missed the opportunity to turn his own King statue into ivory, but this time he can use structural color technology. He can paint a layer of glass on the surface of the statue, and then fly around the huge statue with a drone carrying a high-energy ultraviolet laser machine until the entire statue becomes a colorful miracle, which can shake his old man's majesty to the fullest.

Now many Tibetan people are amazed at their incorrect power of the Dharma King. When they get the magical power of the statue, they are even more convinced.
