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

Chapter 503: Anyone with other ideas will be killed

On the way to the laboratory, I was thinking about my plans for the next period of time.

Superconducting thin film experiments, battery experiments, helping Song Yao make models, and preparing for the report in mid-December, the schedule is packed.

"Very busy."

Xu Qingzhou smiled and shook his head, but he didn't feel tired. After all, trying new things always makes people feel excited.

As soon as he entered the office, he heard Carson excitedly say, "Professor, it seems to be working!"

"Oh, let me see."

Xu Qingzhou came to the computer: "Abnormal changes in the intensity ratio of the D peak to the G peak (ID/IG) of the Raman spectrum, data: ID/IG = 0.38± 0.05, control group ID/IG = 0.42± 0.03."

Carson said: "The graphene defect density is reduced by about 10%, suggesting that plasma may induce the rearrangement of the interface electronic state, but the error range overlaps and requires higher precision testing."

"That's right." Xu Qingzhou nodded slightly and said in a deep voice: "The maximum Jc value of sample B2018010264 reached 1.3×10 A/cm, which suggests that the parameters are highly sensitive and there may be local pinning center optimization."

"Correct."

Carson nodded slightly, then sighed and said, "Unfortunately, the second piece is completely scrapped. We can't do the next set of experiments. We can only refer to some data."

There is a significant effect, but it is limited to a certain project. For example, the defect density above is reduced, but the graphene shows damage.

"You proceed to the next step, ALD deposition."

"no problem."

Carson brought the samples into the laboratory, and Xu Qingzhou sat down in front of the computer and took out a manuscript to verify the calculations.

I hope to find the problem through mathematical means.

4 pm.

Xu Qingzhou gathered everyone together and consolidated the next experimental plan: "In the next experiment, the Nb(OEt) pulse time will be increased from 0.1 s to 0.15 s, and the Sn(CH) pulse time will be reduced from 0.2 s to 0.18 s."

"no problem."

Carson is full of energy.

Xu Qingzhou took two weeks to complete the experimental application and experimental plan. The technology transfer office was also very helpful and drafted the agreement and sent it to Xu Qingzhou on November 2.

Song Yao checked it, added a few small clauses, and made sure that every part was perfect before sending the agreement over.

Everything went well with the superconducting film experiments. Carson and two assistants conducted repeated experiments in the laboratory for two weeks to find reasonable parameters.

After two consecutive busy weeks, Xu Qingzhou gave everyone two days off this weekend, and he himself booked a 4-hour experiment.

According to the information he has read over the years, the current core strategy for inhibiting lithium dendrites mainly revolves around optimizing lithium ion distribution, improving interface stability and regulating deposition behavior.

So he also planned to go in this direction.

On November 11, a heavy rain caused the temperature to drop by half, and the air was filled with a chill.

The scenery of MIT is unique in Boston. At the end of the leaf fall, the deep red, orange, or golden maple leaves are intertwined, and the ancient buildings and natural scenery are integrated, like an oil painting by Van Gogh.

Next to the white SUV, Xu Qingzhou helped Song Yao pull up her collar: "It's so comfortable to hide at home."

"you dislike me?"

"How dare I?" Xu Qingzhou couldn't help but pinch the girl's cheek.

Song Yao curled her lips and raised her chin to make it easier for Xu Qingzhou to adjust her scarf, her eyes looking at the scenery in the distance.

She and Xu Qingzhou have been busy these days. Except in the morning, they basically don't see each other during the day. On the 20th, she has to go to San Francisco with Professor Morton to attend a seminar.

We have to be separated for another six or seven days.

She happened to be on vacation today and wanted to stay with Xu Qingzhou.

The two went towards the laboratory.

Ten minutes later, Xu Qingzhou unexpectedly saw a little girl looking down at a book. "Hey, aren't you taking a break?" "Professor Xu, I have nothing to do, so I came here to read a book."

Sun Simin said embarrassedly, and suddenly noticed Song Yao behind Xu Qingzhou, and suddenly became a little excited, "Hello, Senior Sister Song."

"Hello."

Song Yao blinked, not understanding what this little girl was so excited about. However, she had heard from Xu Qingzhou before that this girl was a little introverted, but very talented.

"It seems I don't need to introduce myself. My wife is Song Yao."

Xu Qingzhou introduced Sun Simin to Song Yao: "This is Sun Simin, a sophomore majoring in applied mathematics."

Song Yao enjoyed the word "wife" and nodded to Sun Simin again.

"This is my position. I usually do experiments in it."

Xu Qingzhou pointed to the laboratory inside the transparent glass.

Song Yao looked around curiously. Various instruments were placed in the compact little room.

Xu Qingzhou asked Song Yao to sit in his seat, and without wasting time, he put on his white coat and entered the laboratory. He had brought back all the materials needed for the experiment before the management office got off work yesterday.

In addition, the positive electrode high nickel ternary is also made. There is no other way, this thing needs to be put into a vacuum oven, dried at 80℃ for 12 hours, and the compacted density is 3.4 g/cm.

For the negative electrode material, Xu Qingzhou used lithium metal foil with a thickness of 50-100μm, a purity of ≥99.9%, and a diameter of 12 mm.

The electrolyte needs to be prepared freshly: 1M LiPF is dissolved in EC/DEC, with a volume ratio of 1:1, and then 2% FEC (fluoroethylene carbonate) is added.

The Celgard 2400 diaphragm used has a PP/PE/PP three-layer structure and a pore size of 0.1-0.2μm.

Outside the transparent glass, Song Yao glanced at Xu Qingzhou in front of the glove box, pursed her lips and sighed, "Men who work seriously are the most handsome."

"Senior Song, drink some water."

Sun Simin took the glass of water and timidly handed it to Song Yao. Obviously, although this girl has been outside for more than a year, her social phobia has not diminished.

"Thank you."

Song Yao took the paper cup and didn't stand there stupidly. She looked at it for a while and then sat down in Xu Qingzhou's seat.

Sun Simin said in a teasing tone: "Senior Song, you and Professor Xu are such a good match."

She has a beautiful bun, delicate features, sparkling eyes, a high nose bridge and the fair skin that girls envy the most.

The most attractive thing should be the powerful aura that can make people feel inferior.

Song Yao said thank you again and was very impressed by this discerning junior schoolmate.

Once you start talking in front of your idol, you can't stop.

"Senior, are you and the professor going back to China next year?"

"Well, if it's earlier, it will be June, and if it's later, it will be August." Song Yao answered while holding the water cup, feeling a little confused. Didn't Xu Qingzhou say that Sun Simin was very introverted?

"I said I'd apply to be the professor's graduate student later."

Sun Simin paused and explained hurriedly: "I just simply think the professor is amazing and want to learn from him."

“I didn’t misunderstand.”

Song Yao shook her head and looked up at the young man in the laboratory, who still looked a bit like a teacher.

As for the rest, don't worry.

Dare to think differently.

Beat him to death in one fell swoop.

Of course, there should be no such opportunity. After all, although this guy usually looks nonchalant, he has his own bottom line.
