Huayu for engineering students

Chapter 307 Usage of Color

The publication of "Nature" has not been promoted as much as "Science". After all, there is a bonus for the first time, and the second time, or the second time so close, it is not so fresh.

However, XiaTV still sent an interview team to interview the entire project team. The current "growth method" has a high level of confidentiality and is not suitable for large-scale publicity, so the equipment is swept away, and even the company commander Nothing was photographed.

On the contrary, the door of the laboratory with the sign gave a close-up. It was modified from an ordinary laboratory. The room was not very big, and the laboratory was only a hundred and ten square meters in total. There were special crystal growth equipment and equipment for the "growth method" inside. Some testing instruments.

I didn't hold a press conference like last time. After all, this research result is still inferior to graphene.

Just a brief announcement in the backyard of the main building, and Xia Shi interviewed the main researchers, and it was all done.Anyway, there will definitely be a few more young scientists born this time, and Wang Xu will definitely show his face again and again.

In any case, starting point news still has to be published. Technology is the primary productive force, so it must be publicized. What's more, this time it can directly drive the industry, so the industry seminar must also be held.

However, Wang Xu lacked interest in those things, and senior brother Yuzhuo just followed up. The benefits in this area were too great. To be honest, Wang Xu couldn't even imagine how big the market would be in the end.

However, the real inventor in the previous life really didn't get much money, mainly because of the investment from that small-time company, and the disagreement over the patent ownership of the research.Wang Xu does not have this problem here. The patent is very stable and the ownership is also very clear. It is estimated that he can get more.

Wang Xu has participated in many seminars recently, more like a supervisor than a doctoral student. It can be said that Shuimu University has left Wang Xu's footprints everywhere.

Wang Xu dares to say that he knows Mizuki better than anyone else in this life, he can even dig out the corner of the laboratory, well, yes, no one knows Mizuki better than him.

Of course, the reverse is also true. Now in the departments of Shuimu, there is no one who does not know Wang Xu. The older ones are called Xiao Wang, the younger ones are called Wang Bo, and those who are not in the same circle are generally called Second Brother.

It can be said that Wang Xu walks sideways in Shuimu, which is basically in line with the facts. At least his motorcycle will not be stopped no matter where he goes, even if motor vehicles are generally not allowed to go there, such as the main building.

Recently, Wang Xu went to the Department of Chemistry and Chemical Engineering a lot, mainly because of the color series. If he wanted to get a standard color card, he had to have warm colors, cool colors and more colors, and then slowly mix them out according to his artistic accomplishment.

Wang Xu provides many kinds of colors, and almost any color can appear in harmony with each other. If you use RGB or CMYK, you can easily mark the specific color.

But all colors come from basic chemical products. In actual production, various colors are often used. For example, few people use red and yellow to mix green, but use green mixed with some other colors to make Mediation, this is what people do when they paint or match industrial colors.

As for the color palette, it shows the color matching externally, and internally shows which basic colors are used to mix these colors.

During this process, it is also necessary to avoid various chemical reactions between the mixed colors. For example, if the more commonly used lead white is mixed with a sulfur-containing color, it will become a mass of black, which is not the color itself. Color reaction, but chemical reaction too.

Fortunately, the various colors provided by Wang Xu are relatively stable, and they are not the kind that are prone to chemical reactions when used in industry or art. Otherwise, there are so many colored things, why would they break their heads for a patent? .

The Department of Chemistry has been reporting frequent successes recently, and a large number of new colors have been produced, making it impossible for professors. After all, Wang Xu requested that original projects cannot participate in the second round, so he had to amend the rules later, and original projects could not lead the second round.

Anyway, it's all kinds of chaos, and then adjust it, then go wrong, and then modify it. I stumbled all the way but ran extremely fast.

This really fits with the style of the 90s. It feels like the whole of China is full of reckless characters. Too many things are done first, and then changed. Of course, there are not a few people who are unlucky because of this.

The production process of this lot of colors is ready-made, and the trouble may be promotion and publicity. It is said that the chemical factory in the imperial capital has expressed interest. Unfortunately, they are facing relocation, and the efficiency of their work is not high recently.

In fact, the color can be roughly divided into light transmission, reflection and fluorescence from the optical characteristics. What passes is called light transmission, and what is reflected is called reflective light.

Translucent ones are generally used to make translucent optical lenses and the like, while reflective ones are various printing, painting, and paint pigments.

None of these materials change the actual wavelength of incoming light. For example, if only pure red light were incident, an ideal blue pigment would appear black because all the incident red wavelengths are absorbed and none Blue is incident, so there is no reflection.

The fluorescent one is quite special, it absorbs light of one wavelength and radiates light of another wavelength, that is to say, it has the characteristic of changing color. This thing is very interesting, and it is widely used in many light sources now. For example, a yellow phosphor that absorbs blue light and emits green light.

Just reading the introduction of this feature can make a group of laymen stunned. So, the question is, what color is this thing?

The series of pigments given by Wang Xu contain a lot of fluorescent materials, among which several simple ones have been tinkered with by the professors of the Department of Chemistry.

At this moment, Wang Xu could no longer take care of everything. He only knew that he could get out a lot of things, but he was really at a loss as to what to do with these things.

For example, the fluorescent powder mentioned earlier was produced by the Department of Chemistry, but I never knew what to use it for.In the end, a professor from the chemical engineering department painted this thing on the blue light diode, and then it became a green light diode immediately, and the cost was directly reduced by more than half compared with the production price of the green light diode.

Then there is another paper, another patent, and another teacher with promising prospects.

Anyway, everyone's brains are very big now, and even the Department of Chemistry has held several expanded technical achievement exhibitions, calling teachers from various departments to help think about what these things can do.
