Chinese entertainment for engineering students

The publication of "Nature" did not promote it with as much fanfare as "Science". After all, there was a bonus the first time, but the second time, or the second time so recently, is not so fresh.

However, Xia Shi still sent an interview team to interview the entire project team. The current confidentiality level of the "Growth Method" is quite high and is not suitable for large-scale publicity, so the equipment was swept away, even the company commander Nothing was photographed.

However, there is a close-up of the laboratory door with the sign on it. It is a modified ordinary laboratory. The room is not very big. The total laboratory is only 100 square meters. Inside is the special crystal growth equipment for the "Growth Method" and Some testing instruments.

There was no press conference like last time. After all, this research result is still inferior to graphene.

Just a brief announcement in the back yard of the main building, Xia Shi interviewed the main researchers, and everything was settled. Anyway, a few more young scientists will be born this time, and Wang Xu will definitely show his face again.

In any case, Qidian news still needs to be published. Technology is the primary productive force and must be promoted. What’s more, this time it can directly drive the industry, so industry seminars must be held.

However, Wang Xu has no interest in those things. Brother Yuzhuo can just follow up. The benefits of this area are too great. To be honest, Wang Xu can't even imagine how big the market will be in the end.

However, the real inventor in the previous life really didn't get much money, mainly because of the investment made by the company in his early days, and the ownership of the research patents were also different. Wang Xu doesn't have this problem here. The patent is very stable and the ownership is clear. He probably can get more.

Wang Xu has participated in many seminars recently, and is more like a mentoring professor than a doctoral student. It can be said that Wang Xu's footprints are everywhere at Shuimu University.

Wang Xu dared to say that he understood Shuimu better than anyone else in this life. He could even dig out the laboratory in the corner of the corner. Well, that's right, no one understood Shuimu better than him.

Of course, the reverse is also true. Nowadays, everyone in the Shuimu departments knows Wang Xu. The older ones are called Xiao Wang, the younger ones are called Wang Bo, and those who don't know each other are usually called Er Ge.

It can be said that Wang Xu walked sideways in Shuimu. It can be said that it is basically consistent with the facts. At least his motorcycle will not be stopped no matter where he goes, even if the place generally does not allow motor vehicles to pass, such as the main building.

Wang Xu has been visiting the Department of Chemistry and Chemical Engineering a lot recently, mainly because of the color series. If he wants to get a standard color card, he has to have a variety of colors, including warm and cold colors, and then slowly mix it out based on his artistic accomplishment.

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

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

The color palette shows the color matching externally, but internally it shows the basic colors used to mix these colors.

In 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 black, which is not the color itself. Color reaction, but chemical reaction.

Fortunately, the various colors provided by Wang Xu are relatively stable and are not prone to chemical reactions when used in industry or art. Otherwise, if there are so many colorful things, why would you break your head for a patent? .

The Department of Chemistry has been reporting a lot of good news recently, with various new colors being produced in large quantities, so that there are not enough professors. After all, Wang Xu requested that original projects not participate in the second time, and later had to modify the regulations so that original projects could not dominate the second time.

Anyway, it was all kinds of chaos, and then adjustments were made, problems occurred again, modifications were made again, and I stumbled along the way but ran extremely fast.

This really matches the style of the 1990s. It feels like the whole of China is emphasizing the word "reckless". Too many things are done first, discussed later, and then changed. Of course, there are not a few people who are unlucky for this.

The production processes for these many colors are all ready-made. 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 their work efficiency recently is not high.

In fact, colors can be roughly divided into light transmission, light reflection and fluorescence based on optical properties. The optical principles of light transmission and reflection are actually the same. Both materials absorb light in certain bands and transmit or reflect light in other bands. What passes is called light transmission, and what reflects is called reflection.

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

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

The fluorescent one is more special. It absorbs light of one wavelength and radiates light of another wavelength. In other words, it has the property of changing color. This thing is very interesting and is now widely used in many light sources. For example, a yellow phosphor that absorbs blue light and radiates green light.

Just looking at this feature introduction can confuse a group of laymen. So, the question is, what color is this thing?

The series of pigments given by Wang Xu contain a lot of fluorescent materials. Several simple ones have been tinkered with by professors from the Department of Chemistry. They have quite good luminous rates and beautiful colors. They should have many applications.

At this point, Wang Xu could no longer handle everything. There were many things that he only knew he could get out, but he was really confused as to what they could do.

For example, the chemistry department has developed the phosphor I just mentioned, but they still don’t know what it should be used for. Finally, a professor from the Department of Chemical Engineering painted this thing on a blue light diode, and it immediately became a green light diode, and the cost was more than half the price of producing a green light diode.

Then comes another paper, another patent, and another teacher with a promising future.

Anyway, everyone has a lot of imagination now. The Chemistry Department has even held several expanded technical achievement exhibitions, convening teachers from various departments to help think about what these things can do.
