I am devoted to scientific research, but you want to trick me into having a love relationship?

Chapter 670: One step closer to solving the lithium dendrite problem

"No amount of talk is as good as producing tangible results."

"The pressure suddenly came."

Xu Qingzhou stood by the window for a few minutes, relaxing his mind. He took a deep breath, smiled, and turned to sit back down at the table.

When I went to the lab in the morning, Zheng Xu said that the new batch of test results would be available in the afternoon, and he retrieved the experimental data from the computer.

At this time, at Kyoto University, School of Economics.

"It's very well written, it's already at the level of a top journal." In the office, Li Daiyue nodded, a satisfied expression on her face.

On one side, Han Shiyi was full of admiration. She rarely heard praise from Professor Li. The word "very good" was almost equivalent to "perfect".

"Due to time constraints, we are unable to develop a regulatory framework optimization plan."

Song Yao still felt a little regretful.

"That's impressive. When I graduated with my PhD, I revised my dissertation countless times."

Han Shiyi exclaimed from the side, "Moreover, if you break this paper down, you could probably submit it to two core journals."

"Forget it, it's too much trouble."

Song Yao shook her head. It would take several days to disassemble the papers, and she wasn't under pressure regarding the number of papers.

"The quality of the thesis is more important than the quantity. By the way, the defense is scheduled for May 16th, a Saturday. You should prepare well, as many professors will be attending the hearing."

"Yes, I'll be ready."

What Li Daiyue liked most about this student was his attitude. She took a sip of tea and asked, "How's your company doing?"

Song Yao explained the situation of Zero Point Technology to Li Daiyue in detail.

She paused for a moment, then revealed another purpose of her visit: "Professor, Xu Qingzhou and I have discussed this, and if you are willing, we would like to invite you to be a consultant for Zero Point Technology."

Li Daiyue is a big name in China's economics field. She has served as a market consultant for companies like Tencent and Huawei, making her an absolute top choice.

"They really want to drag me over to be a laborer."

Li Daiyue chuckled, but didn't hesitate much. After thinking for a few seconds, she nodded and said, "Okay, I'm stepping down from my position at Tencent this year, so I'll show it to you."

"Thank you, Professor."

Song Yao said sincerely.

In the past two years, Li Daiyue has resigned from two consulting positions at companies. Previously, in addition to Tencent, she was also responsible for overseas investment and strategic planning consulting services for Xia Guo Petrochemical Group, as well as research on internet finance and international trade policies for Alibaba.

However, since I needed to focus my main energy on the book I was currently publishing, I ended up only keeping the Penguin platform.

Tencent is one of the most representative high-tech enterprises in China.

Currently, Li Daiyue is still responsible for Tencent's intellectual property strategy, including patent mining, risk control, and other related matters.

See Weizhi book.

According to Li Daiyue, one can understand the current market situation in Xia Kingdom by observing the movements of penguins.

It's obvious that Li Daiyue is planning to quit her job at Tencent for Song Yao's sake.

"You've already called me teacher, why are you still thanking me?"

Li Daiyue smiled and shook her head.

To be honest, it's already quite impressive that my protégé has achieved this level of success. But no matter what kind of company it is, it will encounter some troubles more or less, so even if he's just protecting and supporting them, it's still a challenge.

In May, the weather gradually gets hotter, and it already has the feel of summer.

The research institute is busier than ever before.

Both the lithium dendrite and shuttle effect groups are frantically working to meet deadlines.

On May 4, the institute held an inaugural meeting for the nuclear fusion group. The following day, the fusion group also entered the full-scale equipment commissioning phase.

Xu Qingzhou was busier than ever. He shuttled between the three experimental groups, personally overseeing the progress of each group's experiments, and hardly had a break.

A week later, the lithium dendrite group had submitted three experimental plans, screening materials from three directions: nitrogen doping, metal synergy, and quantum dot confinement effect.

Lithium dendrite experimental group.

Zhao Shengwen's office.

"The inherent size-dependent quantum effect of quantum dots is a key characteristic, therefore we focus on selecting quantum dots with a particle size ≤ 5 nm."

Carbon nitride quantum dots (CN) supported by porous carbon nanofibers, cadmium sulfide quantum dots (CdS) composed of FeCo alloy nanoparticles, and zinc selenide quantum dots with Ni-MOF-derived carbon framework as the metal component.
Currently, a total of 12 quantum dot composite materials have been selected.

Looking at the data on the computer screen, Xu Qingzhou nodded slightly and said with a smile, "Seeing the data puts my mind at ease. It means that our overall direction is correct."

"Yes, all three sets of quantum dot composite materials being studied have shown that they have an inhibitory or even restraining effect on lithium dendrites. If it weren't for you, we would never have imagined that quantum dot composite materials could have an effect on lithium dendrites."

Zhao Shengwen said with a touch of emotion.

Xu Qingzhou was looking at the blueprints when his gaze paused, and he pointed out several sets of data. "These three sets of data show an increase in conductivity of more than 40%, and in the electron microscopy analysis, the lithium deposition roughness Ra is < 5 nm."

"Looks like you've noticed it too. This place is rather strange. I already had Yunfei take it for in-depth analysis this morning. Oh, speak of the devil and he appears."

Zhao Shengwen looked at Gong Yunfei as he walked in and asked, "What did you find?"

"The testing team found Ti in samples No. 10 and No. 13."

As he spoke, Gong Yunfei handed the test report to Xu Qingzhou, and Professor Zhao Shengwen also came over.

On the other side, Gong Yunfei was not reserved. He fetched some water, drank it down, and then sat down to wait for instructions.

10 minutes passed.

Xu Qingzhou and Zhao Shengwen have finished reading the report.

"Nitrogen doping is uniformly distributed in the crystal lattice, forming stable Ti-N bonds and enhancing Li anchoring ability."

Xu Qingzhou's gaze darkened, and for some reason, he felt that he was one step closer to solving the lithium dendrite problem.

That's how experiments work: through iteration, you gradually narrow down the scope until you get what you want.

"But in sample 6, the Ti element significantly disrupted the conductivity and catalytic activity, which caused the sample's performance to drop sharply. You see, samples 2 and 7 were even scrapped."

Zhao Shengwen frowned.

"Perhaps there's a problem with the mechanism of action."

Even in the same experiment, it is impossible to guarantee that all added reagents, catalysts, etc. are exactly the same. Changes in parameters can cause performance to go to two extremes.

Xu Qingzhou pondered for a moment and continued, "This may be an important discovery. I think we can have the testing team work overtime to test the samples again, focusing on the Ti element."

"Yunfei, take two people with you to help the testing team."

Zhao Shengwen agreed and instructed Gong Yunfei.

"it is good."

Seeing that the two big shots looked very serious, Gong Yunfei didn't waste any time and told the two men to carry the sample boxes and head to the testing center.

"Senior Brother Gong can now stand on his own."

Xu Qingzhou watched Gong Yunfei's departing figure with a sigh.

“He’s talented, but he’s too playful. If he had half of Wang Wei’s composure, I wouldn’t have to worry about anything.”

Zhao Shengwen shook his head, sighing with a hint of disappointment.

"I think Senior Brother Gong's attitude is quite good. Doing experiments is inherently boring. If there isn't someone to liven things up, everyone will be bored."

Xu Qingzhou said jokingly.

"I have to say, if he were like that kid Wang Wei, the lab would be much less fun."
