Huayu for engineering students

Chapter 106 Graphene

Looking at Tang Yun, who had regained her vitality and rushed towards the tailor shop full of energy, Wang Xu smiled in relief.

Wang Jinghua looked on coldly, she had learned how to paint cakes from this little man, isn't he just doing his best here, and enjoying it so much.Wang Jinghua's husband said more than once that she was brainwashed, but she couldn't say a word of rebuttal.

It was indeed brainwashing, that little man was so good at fooling around, his blood boiled with just a few words, he agreed on the same day, and joined the job in two days, as if he had been lowered.

But the benefits are also real. Not to mention the salary, the bonus is not easy to pay, but the daily meals are basically free.

Although Wang Xu hasn't come back yet, this small recording studio has already spread among the major record companies just by virtue of the reputation of recording two singles.

There was an endless stream of colleagues who came to visit, but they never stopped. In just ten days, her business card case was almost full.

Wang Jinghua's name is no longer completely unknown, and even the head of the department there had heard of her name when she went to Yangyin to contact and cooperate last time.A world-class recording studio, that's what the professionals who have been there say.

The only disadvantage is that it is too small, and can only accommodate a 5-member band, otherwise recording symphony and piano music is the place where this level of recording studio should play a role.

She has already received cooperation invitations from several record companies to record. Although they have not yet been finalized, they are really promising in the future.

Considering that the blueprint Wang Xu drew for her is being realized step by step, and the promise to her is becoming reality step by step, it can be said that Wang Jinghua loves and hates this little boss.

The top-notch landscape stereo in the reception room was rented by Wang Jinghua from a friend. It was only because Wang Xu, a paranoid, was unwilling to buy a set of stereos, and had to wait until she came back from Xiangjiang to make it herself. .

But it was the recording studio created by this paranoid man himself, which turned out to be the top in the industry, the world's first-class.At first, Wang Jinghua didn't believe it, but after listening to their recorded singles, several Yangyin experts kept praising them, which made Wang Jinghua completely relieved.

This little boss can let go of everything, but when it comes to equipment, he is simply unwilling to make do with it.Wang Jinghua couldn't help slandering Wang Xu secretly, but she didn't know that this was actually the result of Wang Xu making do.

No matter how much Wang Jinghua slanders her, she actually maintains a lot of respect for this little boss. Although his career seems to be a good one, but almost every achievement of his has reached the peak that others can't reach in a lifetime.

Such a fairy cannot be overestimated no matter what, not to mention, the conditions Wang Xu gave are already very rare.After all, even if a general manager is hired in this era, it is generally a salary plus bonus model, and at most a performance commission is given.

It can be said that there is no one like Wang Xu who directly gives stock options.Even if such a model has not yet become popular in Ugly Country, options did not become a standard configuration for new enterprises until Internet companies became popular.

Wang Xu didn't know and wouldn't care about Wang Jinghua's slander, because he was already planning to go back to school, and his next work needed to start.

It was still early, and Wang Xu didn't plan to have lunch with Wang Jinghua anymore. Riding on the long-lost motorcycle, Wang Xu really felt eager to reunite with his old lover.Accompanied by the familiar roar of the engine, Wang Xu galloped towards Mizuki.

His next important experiment was also a technology derived from the microphone, but that technology was too high-end, and he couldn't directly take it out, but after analyzing the data in detail.

He knew that a good opportunity was in front of him again, and this should be a research that could establish his scientific research status.At the same time, it is also a favorite plagiarism study of many seniors who travel through time, tearing the tape.

Smart readers may have already guessed, yes, the thing Wang Xu wants to do is graphene.To be honest, he has long forgotten that there is still such a big leak to pick up.

This is really a must-have skill for the hero of the time-traveling novel ten years ago, but unfortunately it was abandoned by the younger generation. It's too simple, no challenge.

Wang Xu is not afraid of simplicity. It is only 91 years now, and the two real discoverers should still be in middle school, so there is no problem with the time.But the problem is, who said tearing tape is easy.

It is not difficult to tear the tape, just stick the pure graphite flakes on both sides of the 3M tape, and then tear it off.

This kind of tape, Wang Xu, was afraid that he would buy fakes in the capital, so he brought a lot of them back from Xiangjiang.

The difficult thing is how to make sure that the one you tear out is thin enough, because graphene is transparent, almost completely transparent, and its light transmittance can reach close to 98%.

This data may not be very familiar to readers. You only need to know that the light transmittance of ordinary lighting glass is about 80%, and the top-level lead-containing optical glass plus transparent film can achieve about 95%.

Such a high light transmittance means that visible light will directly pass through this thin material and directly shine on the tape, making it impossible for you to distinguish it.

Moreover, all graphite is not in an ideal state. It is not flat and arbitrarily pasted on a layer of graphite, but mixed together at various angles and directions.The process of tearing will also squeeze and stack the edges of this material in various ways, forming a more chaotic situation.

In the previous life, the two doctoral students guarded the scanning electron microscope and observed continuously for several months before they finally found a graphene monolayer with a diameter of only 500 nanometers in thousands of photos, finally proving that graphene exist.

And how much does it cost to take a photo with a scanning electron microscope, sorry, it's about 1000 yuan.Fortunately, Mizuki's scanning electron microscope is quite new, and it is already fully digital. You can directly view the shooting results on the computer, without having to develop the photos like before.

But Wang Xu is a student, he can't occupy the electron microscope for a long time, if he can use it for two days, it's a big deal.

So he had to find a way to increase the chance of hitting, that is to say, he had to make sure as much as possible that there was a single layer of graphene on the sample and where it was probably located before sending the sample for shooting.

Wang Xu's physical perception is very good, but not at the nanometer level, but his naked eyes can distinguish the intensity of light, and it is true that the change of light transmittance is less than 1%.

Therefore, according to the very slight change in light transmittance, Wang Xu can indeed roughly determine which area has a higher probability of having single-layer graphene, and thus finally increase the hit probability. The disadvantage is that it is more troublesome.
