Professor Tang is indebted to Bai Song. He is a treasure professor. He is not only an expert in chemistry, but also in fields such as physics, which is not very related to chemistry, his level is much higher than Bai Song's.
However, Professor Tang is very busy, so after he has no open classes, Bai Song will not ask him any questions in private.
Therefore, when encountering something that Professor Tang felt was very problematic, Bai Song would definitely do his best. If Professor Tang felt it was inconvenient, how could Bai Song let the other party come to him? He asked Professor Tang for the address and ran over immediately.
Professor Tang was in his office. When Bai Song brought two people in, 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? Just tell me, I'll go through fire and water for you." Bai Song said after seeing that Professor Tang seemed to be hesitant to speak for many times.
"My lab seems to have been robbed." Professor Tang looked around: "But I'm not sure."
"Ah? Your experimental results were stolen?" Bai Song was shocked.
He knew what level of person Professor Tang was, and he also knew the general purpose of the thing Professor Tang was working on recently.
Although the field of quantum chemistry seems 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 long-standing problem. Whoever solves it will be the father of the future.
Lithium batteries still have a long way to go in terms of improving their energy density, charging and discharging efficiency, safety, and so on.
Similar to the electroplating problem in the electrochemical industry, it is limited by the diffusion rate of lithium ions in the electrolyte. When the current reaches a certain level and is maintained for a certain period of time, the cations are consumed in the electrolyte near the deposition electrode, breaking the medium-sized balance and forming local space charges, thereby generating dendrites.
This is the origin of common dendrites, and it is easy to understand.
Without going into too much detail, in short, Professor Tang’s research is to study more stable electrolyte additives.
Recently, there may be a significant breakthrough in laboratory experiments.
But problems also arise.
First, it is not certain whether the item has been stolen.
Only Professor Tang and a few of his most beloved students had permission to enter his room, but from the time he left until he came back, his students stayed by his side.
The only reason he suspected the theft was that the freeze time on his computer had changed.
Screen freeze time, this is what Mr. Tang said himself, and he demonstrated it in front of Bai Song.
This situation rarely occurs with current mobile phones and computers because their performance is very good. However, on computers or mobile phones that are a little laggy, the following phenomenon may occur: for example, at 9:05, after your computer/mobile screen is turned off, the moment you suddenly turn on the screen, the screen will stay at 9:05 for a moment and then change to the current time.
Bai Song and Professor Tang didn't know what this thing was called, but Bai Song nodded to indicate that he also knew about this situation.
Professor Tang locked the door and left the laboratory at 9:05 in the morning.
The reason why he remembered the time so clearly was because he had to attend an event at 9:15, so he arrived ten minutes early and brought his favorite student with him.
I returned to the laboratory around eleven o'clock. The moment I turned on the screen, I saw the time at the beginning was 10, but I didn't see the minutes behind it, and the time became 11:09.
In other words, the computer was operated by someone at around 10 o'clock.
This conjecture makes sense, but there is no evidence at all.
This laboratory is a relatively important laboratory, but it is not a truly confidential laboratory and does not have such strong anti-theft equipment and level.
This laboratory is windless and almost dust-free, and it is even more impossible for insects to exist. If something moved the mouse, it is almost impossible. Therefore, such details are worthy of Professor Tang's suspicion.
Professor Tang still cannot confirm whether the items were copied by someone.
Second, he didn’t know what was lost.
The data was intact, so what was copied away? Professor Tang had no idea.
There is a lot of data in the computer, and because it is precious, Professor Tang backs it up every time, which becomes a bit redundant over time. And there is no trace of the folder opening and closing on the computer.
Therefore, Professor Tang did not call the police rashly.
Calling the police may not be a good thing.
For someone at Professor Tang's level, researching this kind of thing must be related to business. If this matter were made public, and if it was just a misunderstanding, there would definitely not be any good rumors.
Third, he didn’t know whether the lost things had any value.
In fact, in the past few days, Professor Tang has done a few more experiments to verify some results, but his mood is very unstable now, and it is difficult to verify. He can't help but doubt his students.
…
Bai Song knew why Professor Tang was looking for him.
Professional matters should be done by professionals. Obviously, Bai Song is the most professional person that Professor Tang can trust.
"Professor, I can guarantee that this matter will be kept 100% confidential, but I have a request." Bai Song said directly: "My two brothers are also police officers, 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 this.
"Wang Huadong? He can't do that. He is in a relationship with your student Ding Jianguo, which could affect the investigation."
Professor Tang glanced at Bai Song and found that Bai Song was surprisingly objective. He thought for a moment and asked, "Are those two friends of yours outside reliable?"
"Born and died." Bai Song said.
Professor Tang no longer hesitated: "Okay, my friend, I believe you."
…
Maybe Bai Song doesn’t know that the things Professor Tang talked about may be worth only tens of thousands of yuan, but they may also be worth billions or even more.
Many scientific research projects, if they fail, are only of reference value, but once they succeed, especially patents related to lithium batteries, each one may be worth countless dollars.
Bai Song doesn't know that much, so he doesn't feel that much pressure.
Wang Liang also understood Bai Song’s words, and patted his chest to promise to keep the matter confidential.
Liu Shuyuan was well-informed and knew how important this thing was. At this moment, the image of Bai Song in his mind became mysterious again. Why could such a great professor find Bai Song?
…
To be honest, this matter must rely on Wang Liang. If there is no Wang Liang, Bai Song can still operate the computer, but he can only operate it.
How could Bai Song know how to restore the computer's previous operations?
After a series of operations by Wang Liang, he finally came to a conclusion that some data had indeed been copied more than half an hour ago. Fortunately, the computer was not restarted, otherwise Wang Liang would not have been able to find it.
Everyone's faces turned pale at this conclusion.
