The publication “Nature-Communications” said it was a bird of paradise feather.
Researchers at Yale University used spectrophotometry and scanning electron microscopy techniques to discover that the black feathers of the bird of paradise can absorb up to 99.95 percent of the direct light. They are so black that you can't even find them. with a flashlight.
The black feathers of some birds of paradise are caused by unique microstructures in the feathers, with vertical and diagonal rows of feather branches. These microstructures allow the feathers to absorb light through the melanin rod layer and the keratin layer. This alternately causes interference and diffraction of light. Why are you doing this?
Let's talk about the Bird of Paradise first
The Bird of Paradise is the most beautiful family of birds in the world. Its magnificent appearanceue is its most important characteristic, which is why it has become the most beautiful family of birds in the world. the most famous bird in the world. In different places, they are also known as "bird of paradise", "solar bird", "goddess bird", etc. What's more interesting is that most birds of paradise like to fly against the wind, perhaps because the tailwind ruffles their beautiful feathers, which is why they are also called "wind birds."
Legend says that the Bird of Paradise is a divine bird of the sky that feeds on dew and nectar. It emits bursts of charming music when it flies. He seeks freedom and happiness and lands only once in his life. It's their life. The destination and homeland of the world - the island of New Guinea in the South Pacific. Papua New Guineans not only strongly believe in this legend, but are also proud of it. They use this birdrare, brightly colored with magnificent tail feathers as their mascot and paint it on their national flag, national emblem and civil aviation planes, symbolizing freedom. and happiness.
There are no wild beasts or wild cats in the tropical jungles of New Guinea. Birds of paradise have almost no natural enemies. Over the years, they evolved without worries and eventually acquired a set of extremely beautiful birds. colorful feathers.
According to word of mouth, the bird of paradise is very “infatuated”. But in fact, birds of paradise are very passionate. Most male birds are "playboys" and will accept virtually any female that comes to their door.
Magnificent bird of paradise. When the male bird is courting, he first calls the female bird with a cry. When the female bird lands in front of him, the male bird spreads his wings to form a “wrinkleau » semi-elliptical black, like a large black face. , with a The blue feathers narrow into two blue dots on the curtain, like a pair of bright blue eyes. The blue shield on the chest opens, resembling a large smiling mouth. The whole shape is like a clown mask. Additionally, the male bird also has to open his green mouth and show off his not-so-beautiful singing voice while walking to the tune of "daddy" and repeatedly jumping in front of the female bird to win her heart.
In order to attract more attention from the opposite sex, male birds of paradise will have extremely brightly colored feathers, and soft black feathers will grow next to the colorful feathers. These black feathers have no colorful shine. the feathers are even more dazzling. Helps attract potential girlfriends during courtship.
Everyone is wondering where such dark materials are needed?
The first is the space telescope. In order to obtain the most realistic information about the universe, space telescopes' interior support material had to do everything possible to reduce light pollution, so ultra-black material was used. Of course, this is a specially researched artificial material, not the feathers of a bird of paradise.
Photography field
Many precision instruments require a good light environment and need to reduce light pollution, and this ultra-black performance is necessary for optical instruments.
Solar panels
China is currently the world's largest manufacturer of solar panels and the largest user of solar energy. However, the conversion efficiency of solar panels has always been a problem that has troubled scientists. Learning about the efficiency of absorption of light by the black feathers of the Bird of Paradise is obviously an axis ofe important research for scientists.
Scientists have developed a material called Vantablack S-VIS, which can absorb 99.8% of light. It is widely used, but it is also extremely expensive. We hope that the feathers of this bird of paradise can bring more inspiration to humanity.

Okay.
1. Huameidun pre-filter can remove some precipitated impurities, rust, sand, mud, bacteria and other particulate impurities produced in the pipeline, ensuringthus water security.
2. It can provide better protection for water purifiers, washing machines, showers, high-end faucets, downstream pipes, etc. It can use anti-scaling filter elements containing hydrochloric acid complex phosphorus to enable solar equipment to, water boiler plays a good anti-scaling function.
