The autumn wind has yellowed the treetops. .

With the arrival of September, students who have been on the long vacation for more than three months have begun to return to campus. As the students returned to school, Princeton, who had been vacant for many days, was finally revived.

At the same time, playing for two weeks at Princeton, it is time to report things.

She drove her to the airport entrance, and Lu Zhou helped her to pull the suitcase out of the trunk.

After picking up the suitcase, Xiao Yan’s expression was a bit sad: “Brother, I am leaving.”

"Well, be careful on the road, get off the plane and go home directly..." Lu Zhou thought about going, but still felt a little uneasy. "Forget it, or you will wait for me to buy a ticket, I will send you back."

"You don't have to," Xiao Xiao hurriedly waved his hand and smiled a little. "I am not a child now, I should learn to take care of myself."

Lu Zhou squatted slightly, and a smile of relief appeared on his face.

"Well, that's also true, you should have grown up. Right, mom."

Xiao Yan raised his mouth: "Do not worry, I will talk to my mother, let her not worry!"

Lu Zhou nodded and said in a joking tone: "Thank you, Miss Prosecutor, for raising your hand."

After bidding farewell to Xiao Yan, he stood on the side of the road for a while and kept watching her walk into the airport.

When I walked to the entrance of the airport, I stopped and I turned around and waved my hand.

Looking at the younger sister who waved goodbye to herself, Lu Zhou smiled and lifted and waved.

However, it is coincidental that just as he waved his hand, he was just approaching an acquaintance.

Molina, who was dragging her suitcase out of the airport, noticed Lu Zhou’s beating action and slammed it down slightly.

Obviously, she did not expect the Luzhou to appear here.

Because she has never mentioned with whom, it is the flight that I am going back to school.

Obviously misunderstood something.

Molina, who had opened her brain, had a smile on her lips and walked straight toward the direction of Lu Zhou.

At this time, Lu Zhou also noticed her.

However, just as he was preparing to say hello, she spoke first.

"Thank you, I really didn't think that you would come to pick me up."

Crossing the boat, Molina slid the suitcase into the open trunk and covered the trunk lid.

Looking back at him, she gently shook the pretty blonde, grinning and smiling.

"Looking at this surprise really surprised me, I won't hold you out where you got my flight."

I consciously pulled the door open and sat in the co-pilot position.

Seeing the boat standing outside the car, looking straight at himself, there was no reaction for a long time, and Molina couldn’t help but squint and wrinkled a pair of Liu Mei.

"……Any questions?"

After returning to God, Lu Zhou shook his head and said: "No problem, I am also preparing to return to Princeton..."

Although he felt that his statement was a bit strange, Molina was in a good mood and she did not care.

Pulling the door open, Lu Zhou sat in the driver's seat and took out the key and was about to start the car. He suddenly hesitated.

Although there was nothing to take people back, Molina had sent herself to the airport, but in order to prevent unnecessary misunderstandings, he felt that it was necessary to clarify.

So, before driving on the road, Lu Zhou finally said what he was in his heart.

"By the way, in fact, I just came to send my sister back to China."

Molina: "...?"

......

After Xiaotun returned to China, Lu Zhou’s life gradually returned to the right track.

In the next few days, he was almost three points a day, between the Institute of Advanced Studies, the Frick Chemical Laboratory, and the Dormitory Apartments.

In order to build a logically self-consistent mathematical model and complete his own ppt, he needs more experimental samples.

This may sound cumbersome, but it's okay.

For a mathematician, especially for mathematicians involved in mathematical physics, knowing the results and pushing back the mathematical model is simply too easy.

Of course, this is not entirely for the materialist who does not understand mathematics.

A mathematical model that can be followed regularly can not accurately predict the physical properties of an untested material sample, but it can provide a reference for the experimenter.

For example, to narrow down the scope of the experiment in a probabilistic sense.

In addition, considering the promotion of technology, Lu Zhou also needs to perform multiple Coulomb cycles on the sample, and compare the performance curves of the two materials in Coulomb efficiency by setting the control group of the graphite negative electrode.

The academic community is concerned with breakthroughs, while the industry is concerned with a series of production issues such as cost and safety. Prepare more materials to help increase the bargaining power of patent negotiations.

The only thing that makes him more trouble is that experimenting is a time-consuming thing, especially in dangerous instruments on expensive instruments. The laboratory must be kept.

This living boss usually does not personally do it, usually it is thrown to the younger brother. However, Lu Zhou’s work is a mathematics professor, and the three students who are involved in mathematics are not able to help.

Fortunately, Professor Chiric helped him solve this problem.

He brought a lot of students, except for a few apprentices who often took meetings and experimented, and the rest were basically idle.

When Lu Zhou heard that he had brought more than a dozen master students, he was almost not shocked by this number.

"A dozen master's degrees? Are you coming over with so many students?"

Professor Chiric did not care to say: "Look for a few potential developments, and leave nothing to do with them. Maybe you can't see people when you read them."

Lu Zhou: "..."

Sure enough, a good scholar is not necessarily a good mentor.

When these guys offered the offer, they were like the dealers, and they were self-defeating after they were finished.

Lu Zhou suddenly felt that his boss was not too fucked...

......

In any case, the helper is found.

The next day, Professor Chiric found his boat with his students.

This young man looks like a tall man, not quite like research, but a bit like playing rugby.

However, there is a reference to Professor Chiric here, and Lu Zhou did not feel too strange.

"This is Connie, who I told you. His organic materials, applied mathematics and computers are still in the works. The doctor who just came to me last year should be able to help you." After entering the door, Chirik The professor introduced to Lu Zhou.

The boy named Connie reached out with enthusiasm and looked at Lu Zhou’s face full of worship.

“Hello, Professor Lu, I am very glad to meet you!”

Being embarrassed by this enthusiasm, Lu Zhou held his hand and smiled kindly.

"Hello there."

After patted Connie's shoulder hard, Professor Chiric laughed and said, "Well, Connie, what needs to be done has already been explained to you. You are the first person in Princeton's Computational Materials Science, followed by Professor Lu. Study hard, don't humiliate me."

Connie grinned: "Reassure Professor, I will definitely not let you down."

Lu Zhou coughed softly and said: "The first person can't talk, I just did a little work."

"No, no, please don't be humble," Professor Chiric said with a hand and said seriously. "There are many papers published in Nature in the past decade, but they can cause such a sensational effect paper, both hands are counted. Come over, it’s no exaggeration to say that you have changed the industry. If this is only a small job, what kind of work can be said to be great?"

Seeing that Professor Chiric said this, Lu Zhou smiled and stopped explaining.

Whether it is called great, or give it to the world to evaluate it.

In short, with the addition of Connie, he was finally freed from some tedious and boring repetitive work.

Perhaps it was a cold bench that had been sitting for a long time at Professor Chiric. In order to learn something from Lu Zhou, Connie was also a very good guy.

No matter how many nights I went the day before, the next morning I always appeared in the lab at 6 o'clock in the morning, and I didn't even have a floor in the lab.

In this way, two and a half months have passed in the busy period.

Finally, before the Black Friday in November, Lu Zhou got six samples of lithium negative batteries after completing the Coulomb cycle of 1000-2000 cycles.

The results were very gratifying. There were no exceptions for the six groups of samples. Except for the small cross-section of the negative electrode material, no lithium dendrites appeared.

As for the No. 7 sample as a control group, no pdms material was used, and the copper foil was filled with barium-grown lithium dendrites and completely scrapped. From this, it can be seen intuitively how amazing his research results are.

At this point, all the preparations are finally ready, just wait for the meeting to begin...
