Chinese entertainment for engineering students

After the meeting was over, Wang Xu returned to his small courtyard. Now that he was a private scholar, he could just provide some ideas, so there was no need to work hard for it.

This is not just an ordinary consolation, but a pragmatic attitude.

If you are not in your position, you will not have access to enough information, and you will also be unable to consider it from an appropriate standpoint. Judgments based on incomplete information and incorrect standpoints are likely to go wrong.

From your own perspective, you can provide information, provide references, and even provide solutions, but it is best not to try to influence the judgment of others in your position, even if you know that judgment may be wrong.

After debugging the ion evaporation equipment, the laboratory already had the basic ability to produce blue light diodes. After that, the Department of Electronics took over and began the development of blue light diodes.

At this point, there are actually no special difficulties to overcome. Just mix in the appropriate metals, produce a suitable coating, and then use common methods to generate diodes and test them.

It's nothing more than changes in various parameters and some minor process adjustments, but nothing can be done. In any case, as long as it is produced in the laboratory in advance, Wang Xu will have completed his task.

Wang Xu did not actively conduct experiments this time. In addition to proposing plans, he only provided various guidance. All operations were completed by professors and doctoral students.

He now reminds himself all the time, don't do everything by yourself, it is better to let others practice more than to do it quickly by yourself.

Sure enough, Wang Xu only stared at it for three days, and Zhou Changming, a doctoral student in the Department of Electronics, successfully completed the experiment. Looking at the small diode that emits a long blue light, Wang Xu knew that it was stable.

"Blue light, it's on, blue light, it's on." The two doctors jumped up first, then Wang Xu, and then the two professors who had been staring at the observation without blinking.

Excessive blue light is not good for the eyes, and may even damage the human retina and cause macular disease. Later generations of LCD screens even have to be specially affixed with films to prevent blue light.

But now, haha, who cares, that blue light is so cute.

Cheering, applauding, jumping, hugging, everyone in the laboratory, young and old, vented their stress like children.

This project is the top priority of the entire large project. It can be said that almost everyone's attention is focused on it. You can imagine the pressure on the two professors.

The success of Blu-ray means that the big project has been 80% successful. Even if the remaining sub-projects fail, this project can be said to have achieved unprecedented results.

The technological content of the blue light diode itself is just that, at least it doesn't sound very high-end.

But with blue light, combined with the green and red diodes we already have, our daily lighting, white light, was born.

If one were to select the top ten inventions in human history, Wang Xu felt that the electric light would definitely be selected.

Because that was the first way that humans truly conquered darkness. Previously, the brightness produced by candles and gas lamps could not truly support human activities and could only play a supporting role.

With electric lights, humans can truly carry out complete activities at night, which expands human living space by almost half.

This is the meaning of the invention of the electric light, and diode white light, although it has the same meaning, will definitely play a huge role in the expansion of human living space.

This will be a new type of light source that is cheap and has low energy consumption. If others don’t know it, and Wang Xu doesn’t know it, then the trillion-level lighting market in the future will be led by China. How can this honor not make people cheer?

Although it is only bright now, the chromaticity, brightness, etc. have not been measured yet, but just looking at the brightness visible to the naked eye, we know that this brightness far exceeds the levels mentioned in various previous papers.

This order of magnitude difference is not just that Wang Xu, who has super eyesight, is very confident, but the professors from the two departments who are also staring at him are also very confident. This is really a difference that is visible to the naked eye. Anyone can see it. There's such a huge difference.

"This is already the second disruptive technology. This time it's Nature's turn." Wang Xu exchanged opinions happily with the two professors in a low voice, although this opinion had nothing to do with the achievement itself.

"It's necessary. Last time it was "Science", this time it must be "Nature"." One of the two professors was high-spirited, and his gray hair looked shining.

However, by grabbing the first article in "Science" and then grabbing the first article in "Nature", the Department of Materials may be able to last for twenty years.

After the results are shown, there will be an internal appraisal meeting, paper preparation, and submission. Naturally, Wang Xu does not need to worry about these. In this project, Wang Xu actually plays the role of the project leader.

He will be the corresponding author and first author. The remaining two professors and two doctoral students can only sign two, three, four, and five respectively.

The Blu-ray project actually produced more than this paper. The paper on ion evaporation is confidential, so it was not published. It was just an internal identification, equipment, principle, performance, and improvement. The paper was almost collected together.

At an internal appraisal meeting organized by the Science and Technology Commission and the Science and Technology Commission, eight papers were read and debated, and the final result was the rather complicated evaporation equipment.

Since this equipment is confidential, the patent is also through confidential channels, and future manufacturers will also be conducted by confidential units.

For example, the school-run factory in Shuimu.
