Chinese entertainment for engineering students

"Wang Xu, just let's talk. I see that you have been tossing about this and that. The exam took a lot of time in the previous period, so you don't have to worry about it anymore. I'm really not used to it. Have you come up with any new ideas recently? When you are young, when your thoughts come to you, rush them out. Don't be too old to do so." Professor Yan joked and motioned to Wang Xu to sit down and give Wang Xu the lecturer's position.

"I won't sit down anymore. Let's talk standing up, maybe using a blackboard." Wang Xu shook his head and returned to the lecture position where he had just defended.

The conference room for the defense is actually the classroom where classes usually take place. The students are gone and there is no class. Wang Xu stood still in front of the blackboard. He had actually wanted to do something he wanted to do for a long time. He had been preparing for it for so long, and now the opportunity came.

"Okay, then you can talk freely. You can say whatever you want. Unfortunately, I am on a business trip. He has already said that he wants to hear your thoughts." Professor Duan also spoke.

"Yes, I have been talking about it for a long time, but it was you who caused his business trip. It was not a matter of single crystal copper. It can be said that it was painful and happy at the same time." Professor Yan knew the details and made a joke.

"Okay, I've really had some ideas recently, from both departments. As a result of my random thoughts, teachers can always raise their opinions if they have any." Wang Xu said modestly.

"Okay, don't be humble. If you have questions, we will definitely ask them." Professor Yan urged.

"Everyone may have noticed that the things I toss around are all based on my hobbies. I like music, painting, movies, novels and various entertainment products, and the production of these products is not just for literary and artistic workers. What really supports literary and artistic creation is the technology behind it.

Without the advancement of pigments, painting would not develop. Without the invention of film, there would be no fifth art. Without digital equipment, how would music be popular?

In the previous paragraph, the circuits I made were actually made while tinkering with microphones and speakers.

If you want to make a condenser microphone, you need a membrane material. I thought about what the thinnest membrane would look like, and then graphene came out. Although the actual method of tossing out these things is far from the original desire, this kind of excavation is indeed the cradle of inspiration. "

Wang Xu first forcibly washed away his inspiration. Regardless of whether they believed it or not, Wang Xu himself believed it anyway. That's weird. Wang Xu himself doesn't believe it, but it doesn't matter. These words will be used for propaganda in the future. It doesn't matter whether people believe it or not. If you say it too much, it will be true.

Just like Washington's cherry trees, Edison's bench, and Leonardo da Vinci's eggs, they were not all blown out.

After that, Wang Xu began to explore possible technologies one by one in terms of what exactly is needed in a recording studio.

For the membrane capacitor of the microphone, he conceived a new ion evaporation mode, which he felt could produce a better metal capacitor film. Moreover, this evaporation mode is more uniform and should be applicable to various fields that require evaporation.

And if further research is carried out, this method of ion diffusion may even be used to produce large-area graphene.

Another extension of this approach could lead to growth equipment for producing crystals, such as diamond and single crystal silicon.

In the field of semiconductors, an important branch is gallium nitride. Military fans must be familiar with this thing, so I won’t go into details here. However, crystals of this thing have never been produced. Wang Xu suggested that gallium nitride crystals may be formed in this way.

If there is a gallium nitride crystal, the brightness of the light-emitting diode can be greatly improved. Although it is only a guess, the feasibility is very high.

At present, there are only green and red light-emitting diodes. It’s not that there are no blue-light diodes, but the light is too weak. If gallium nitride crystals are used to increase brightness, will blue light diodes become practical?

With the three primary colors of red, green and blue, can a display screen based on this appear?

In his spare time, Wang Xu had been sorting out the many preparation methods given to him by the system. He discovered that one of the growth methods almost ran through the preparation process of several materials, so he specifically proposed this conjecture here.

But this requires the development of a very complicated equipment, which is really difficult to do by yourself, so it would be great to combine the power of these two systems to do it.

This process is at least another Nobel Prize-level achievement. Of course, it is hard to say whether it will be obtained, but an SNC article probably did not run. In addition, during the research and development process, the number of papers that can be produced is estimated to reach three digits, and there will definitely be many top journal-level results.

If you rely on yourself to copy each item one by one, the efficiency will be too low and the impact on the country will be too small.

But if we just point out the direction, the researchers will be greatly trained and grown. This accumulation of talents is definitely more important to the country than producing a single result.

Moreover, Wang Xu believed that in a place where top students like Shuimu were concentrated, there were definitely not a few geniuses, and those geniuses who could be trained in these big projects could also grow greatly.

Talent is the biggest shortcoming of this era. If we want to develop by leaps and bounds, we cannot support it without talent. Wang Xu can buy technology, but these technologies require a large number of people to implement and realize them.

Whether it's true or not, Wang Xu completely puts himself in the position of a top genius, and then lets himself, the genius, guide the way.

Other geniuses are responsible for overcoming obstacles on the road, while ordinary researchers are responsible for adding bricks and stones to this end, and finally building a towering scientific research building.

Now, in the plan put forward by Wang Xu, a new material preparation method was introduced to identify scientific research gaps one by one, and then he thoughtfully proposed possible solutions.

Among them, there are vacancies in all aspects such as equipment development, method research, theoretical explanation, etc., all of which need to be filled by researchers.

Once implemented, it will not be comparable to the scale of the previous student project.

Wang Xu talked non-stop for more than an hour, and the professors in the audience changed from listening with relaxed expressions to taking quick notes with serious expressions, and even later brought in a tape recorder to record on the spot.

"I wanted you to briefly talk about your idea, but you made such a big bomb again. Please tell me what happened.

Okay, thanks for your hard work, all the professors will go back and sort out their thoughts. When the semester starts, we will get together again, summarize what we have sorted out, and discuss it.

Why do I feel that the feasibility is quite high? I estimate that this plan is a great thing.

We still have to report it to the superiors. We may not have enough weight. "

Professor Yan scratched his already sparse hair, completely unaware that there was an extra handful of something on his hand and a handful of something missing on his head.
