Professor Tang is kind to Bai Song, this is a treasure professor, not only a chemistry expert, even in physics, a field that is not very related to chemistry, the level is much higher than Bai Song.

However, Professor Tang is very busy, so after he has no public class, Bai Song will not ask him any questions alone.

Therefore, when encountering something that Professor Tang felt was very problematic, Bai Song must have gone all out, Professor Tang felt inconvenient, how could Bai Song let the other party come to him, asked Professor Tang for the address, and immediately ran over.

Professor Tang was in his office, and when Bai Song and the two of them entered, Professor Tang stood up, poured tea for Liu Shuyuan and Wang Liang, and then called Bai Song to another small laboratory alone.

...

"What's the matter, you just say it, I'm going to the soup. Bai Song saw that Professor Tang wanted to speak many times, and then said.

"My lab looks like it's been a thief. Professor Tang looked around: "But I'm not sure. ”

"Huh, your test results have been stolen?" Bai Song was shocked.

He knew what level Professor Tang was, and he also knew what the purpose of this thing that Professor Tang was working on recently.

Although the field of quantum chemistry looks very high-end, it is actually very down-to-earth, and his research field is closely related to lithium batteries.

The energy density of lithium batteries is a big problem, and whoever solves it is the future father.

The energy density of lithium batteries has a long way to go in terms of energy density, charging and discharging efficiency, safety and so on.

Similar to the electroplating problem in the electrochemical industry, limited by the diffusion rate of lithium ions in the electrolyte, when the current reaches a certain level, the cations are exhausted in the electrolyte near the deposited electrode side after the beach time is maintained, breaking the medium-sized equilibrium and forming a local space charge, resulting in dendrite.

This is where common dendrites come from, and it's easy to understand.

In short, Professor Tang's research is to study more stable electrolyte additives.

Recently, there may be a major breakthrough in laboratory experiments.

But problems also arise.

First, it's uncertain whether there has been a theft.

Professor Tang's room, only he and a few of his most beloved students had permission to enter, but from the time he left until he returned, several of his students were always by his side.

The only reason he suspects the theft is that his computer's screen jam time has changed.

Stuck screen time, this is Donald's own statement, he demonstrated it in front of Bai Song.

Nowadays, mobile phones and computers rarely have this situation, because the performance is very good, but on the computer or mobile phone with a little bit of card, there may be such a phenomenon: for example, when you turn off the screen at 9:05, the computer/mobile phone turns off the screen, and the moment you suddenly turn on the screen, the screen will stay in the interface at 9:05 for a moment, and then become the current time.

What is the name of this thing, Bai Song and Professor Tang don't know, but Bai Song nodded and signaled that he also knew about this situation.

Professor Tang left the lab at 9:05 a.m. with the door locked.

The reason why he remembered the time so clearly was because he was going to attend an event at 9:15, and he mentioned it for ten minutes, and he took his proud protégé with him.

I returned to the laboratory at about eleven o'clock, and the moment I turned on the screen, I saw that the time in front was 10, and I didn't see it for a few minutes in the back, and the time became 11:09.

In other words, at 10 o'clock, the computer was once operated.

There is truth to this conjecture, but there is not the slightest evidence for it.

This laboratory is a relatively focused laboratory, but it is not a secret laboratory in the real sense, and it does not have such strong anti-theft equipment and level.

The lab was windless, almost dust-free, and it was unlikely that there would be any insects, and if something had moved the mouse, it would have been almost impossible. Therefore, such details are worthy of Professor Tang's suspicion.

Professor Tang still has no way of knowing whether or not the things have been copied or not.

Second, what exactly was lost, he didn't know.

There is nothing missing in the data, but what has been copied and taken away? Professor Tang did not know.

There is a lot of data in the computer, and because it is precious, Professor Tang makes a backup every time, which is a bit redundant after a long time. And there is no trace of the computer's folder switch.

Therefore, Professor Tang did not rush to call the police.

If you call the police, this is not necessarily a good thing.

At the level of Professor Tang, studying this kind of thing must be related to the company, if this matter is made public, if it is an oolong, then there will definitely be no good rumors.

Third, he didn't know whether the lost thing was valuable or not.

In fact, in the past few days, Professor Tang has done several more experiments to verify some results, but his mood is fluctuating so much now, and it is also difficult for him to authenticate, and he can't help but doubt his students.

...

Bai Song knew why Professor Tang was looking for him.

Professional things are done by professional people, and it is obvious that Bai Song is the most professional one among the people that Professor Tang can trust.

"Professor, I can guarantee 100% secrecy in this matter, but I have one request. Bai Song said directly: "My two brothers are also policemen, and I need their help." ”

"Is the policeman who came with you last time okay?" Professor Tang didn't want too many people to know about it.

"Wang Huadong, he can't do it, he and your student Ding Jianguo are still in love, and it is easy to affect the handling of the case. ”

Professor Tang glanced at Bai Song, found that Bai Song was rare and objective, and thought for a while: "Are those two friends of yours outside reliable?"

"Birth to death. Bai Song said.

Professor Tang no longer hesitated: "Okay, Xiaoyou, I believe in you." ”

...

Maybe Bai Song didn't know that the things Professor Tang said might only be worth tens of thousands, but they could also be worth billions or more.

Many scientific researches, if they fail, are only reference value, but once successful, especially patents related to lithium batteries, each of them may be worth countless dollars.

Bai Song doesn't know so much, so he doesn't have so much pressure.

Wang Liang also understood Bai Song's words, and patted his chest to ensure confidentiality.

Liu Shuyuan was well-informed and knew how important this thing was, and at this moment, the image of Bai Song in his mind became mysterious again. Why can such a great professor find white pine?

...

To say, this matter must rely on Wang Liang, if there is no Wang Liang, although Bai Song can also operate the computer, it is only an operation.

Restore the previous operation of the computer, where will Bai Song do this?

After a series of operations by Wang Liang, he finally came to a conclusion that there was indeed a copy of the information more than half an hour ago, but fortunately the computer did not restart, otherwise Wang Liang would not have been able to find it.

At this conclusion, everyone's faces turned pale.
