The autumn wind dyed the treetops yellow.
With the arrival of September, students began to return to campus after more than three months of vacation. After the students returned to school, Princeton, which had been empty for many days, finally became lively again.
At the same time, Xiao Tong, who had been playing in Princeton for two weeks, was ready to report.
Lu Zhou drove her to the airport entrance and helped her drag her suitcase out of the trunk.
Xiao Tong took the suitcase and said, "Bro, I'm leaving."
"Yeah, be careful on the road. Go home after you get off the plane …" Lu Zhou thought about it and still felt a little worried. He said, "Forget it, how about I buy you a ticket, and I'll send you back."
"No, no," said Xiao Tong as she waved her hand. She smiled and said, "I'm not a kid anymore, I should learn to take care of myself."
Lu Zhou paused for a second before a smile appeared on his face.
"Yeah, you're right, you should have grown up a long time ago. Oh yeah, about mom. "
Xiao Tong smirked and said, "Don't worry, I'll talk to mom and tell her not to worry!"
Lu Zhou nodded and said in a joking tone, "Thank you, Ms. Prosecutor, for being merciful."
After saying goodbye to Xiao Tong, he stood on the side of the road for a while and watched her walk into the airport.
Xiao Tong stopped at the airport entrance and turned around. She waved her hand.
Lu Zhou looked at his sister waving goodbye to him and smiled. He then waved back.
Coincidentally, just as he was waving his hand, a familiar face walked towards him from not far away.
Molina, who was dragging her suitcase out of the airport, noticed Lu Zhou waving and paused for a second.
Obviously, she didn't expect Lu Zhou to appear here.
This was because she had never mentioned to anyone which flight she had taken to return to school.
Obviously, she misunderstood something.
Molina smiled and walked toward Lu Zhou.
At this time, Lu Zhou also noticed her.
However, just as he was about to greet her, she spoke first.
"Thank you. I really didn't expect that you would come to pick me up."
Passing by Lu Zhou, Molina deftly stuffed the suitcase into the open trunk and closed the trunk lid.
Looking back at him, she gently shook her beautiful blonde hair and pursed her lips into a smile.
"Since this surprise really surprised me, I won't ask you where you found out about my flight."
He opened the car door and sat in the front passenger seat.
Seeing Lu Zhou standing outside the car staring at her without any reaction, Molina couldn't help but frown in confusion.
"… Is there a problem?"
When Lu Zhou came back to his senses, he shook his head and said, "No problem, I'm going back to Princeton too …"
Even though Lu Zhou's words were a bit strange, Molina was in a good mood, so she didn't take it to heart.
Lu Zhou opened the car door and sat in the driver's seat. He took out his keys and was about to start the car when he suddenly hesitated.
Even though it wasn't a big deal to take someone back since Molina had driven him to the airport before, in order to prevent unnecessary misunderstandings, he felt like he needed to clarify.
Therefore, before driving on the road, Lu Zhou finally said what he had been holding in his heart.
"By the way, I actually came here to send my sister back to China."
Molina: "…?"
…
After Xiao Tong returned to China, Lu Zhou's life gradually returned to normal.
Over the next few days, he went back and forth between the Institute for Advanced Study, the Frick Chemistry Laboratory, and his dorm.
In order to build a logically self-consistent mathematical model and complete his PowerPoint, he needed more experimental samples.
Although this sounded troublesome, it was actually not that bad.
For a mathematician, especially a mathematician who was involved in mathematical physics, it was too easy to know the results and reverse engineer the mathematical model.
Of course, this was not just for materials scientists who "didn't understand mathematics".
Even though a regular mathematical model could not accurately predict the physical properties of an untested material sample, it could provide a reference for the experimenter.
For example, it could reduce the scope of the experiment.
Also, because of the promotion of the technology, Lu Zhou also needed to perform multiple Coulomb cycles on the sample. He also needed to set up a graphite anode battery as a control group to compare the Coulomb efficiency and other performance curves of the two materials.
The academic community focused on breakthroughs, while the industry focused on a series of production issues such as cost and safety. Preparing more materials would help increase the bargaining chip of the patent negotiation.
The only thing that gave him a headache was that doing experiments was very time-consuming. Especially when he was doing experiments on expensive instruments, he had to leave people in the laboratory.
The boss usually wouldn't do this himself; he would usually leave it to his underlings. However, Lu Zhou was a mathematics professor, and his three students were all in mathematics, so they couldn't help at all.
Fortunately, Professor Chirik helped him solve this problem.
He had a lot of students. Other than a few students who often attended conferences and did experiments, the rest of them were basically idle.
When Lu Zhou heard that he had a dozen master's students, he was shocked by the number.
"A dozen master's students? Can you manage so many students? "
Professor Chirik said nonchalantly, "Just find a few students with potential and train them. Don't bother with the rest. Maybe you won't be able to read them anymore."
Lu Zhou: "…"
As expected, a good scholar wasn't necessarily a good supervisor.
These guys were like dealers when they gave out offers. After they gave out offers, they left people to fend for themselves.
Lu Zhou suddenly felt that he was too much of a boss …
…
In any case, he finally found a helper.
The next day, Professor Chirik brought his students to find Lu Zhou.
This young man looked tall and strong. He didn't look like a researcher. Instead, he looked like a football player.
However, with Professor Chirik as a reference, Lu Zhou didn't think it was too strange.
"This is Connie, who I told you about. He's good at organic materials, applied mathematics, and computers. He came here last year to study his PhD. He should be able to help you," Professor Chirik said to Lu Zhou.
The young man named Connie enthusiastically reached out his hand and looked at Lu Zhou with admiration.
"Hello, Professor Lu, nice to meet you!"
Lu Zhou was a little embarrassed by the enthusiasm, so he shook his hand and smiled.
"Hello."
Professor Chirik patted Connie on the shoulder and said, "Okay, Connie, I've told you what you need to do. You're facing the number one computational materials scientist in Princeton. Learn from Professor Lu, don't embarrass me. "
Connie smiled and said, "Don't worry, Professor, I won't let you down."
Lu Zhou coughed and said, "I'm not the number one, I just did a little bit of work."
"No, no, no, don't be humble." Professor Chirik waved his hand and said in a serious manner, "There have been a lot of theses published in Nature over the past decade, but the number of theses that have caused such a sensation can be counted on two hands. It's no exaggeration to say that you've changed the industry. If this is just a little bit of work, then what kind of work is great? "
Since Professor Chirik said this, Lu Zhou smiled and didn't explain anymore.
Whether or not it was great would be up to the world to judge.
In short, with the addition of Connie, Lu Zhou was finally freed from some tedious and boring repetitive work.
Maybe it was because Connie had been sitting on the bench for too long, but in order to learn from Lu Zhou, Connie worked quite hard.
No matter how late he left the day before, he would always show up at the laboratory at 6 o 'clock the next morning. He almost slept on the laboratory floor.
Just like this, two and a half months passed by.
Finally, before Black Friday in November, Lu Zhou received six sets of lithium anode battery samples that had completed 1000-2000 Coulomb cycles.
The results were very gratifying. Other than the small folds on the cross section of the anode material, none of the six sets had lithium dendrites.
As for sample number 7, which was the control group, there was no PDMS material. The copper foil was filled with lithium dendrites, and it was completely scrapped. From this, it could be seen how amazing his research results were.
