I failed a course, and the system became my study supervisor.

Chapter 48 PRL New Issue Release (Part )
"What kind of juice do you like?"

Xu Ling asked suddenly.

"Hawthorn, what for?"

Qin Qin, who was looking for experimental equipment on the side, asked puzzledly.

"Hawthorn is so sour, but some people actually like it?"

"I like it, what's your business?"

"Then we'll do an experiment with hawthorn juice and give it to you when we're done. How's that? Are you touched?"

Xu Ling raised his eyebrows and asked in a mean way.

"ill!"

Qin Qin rolled her eyes, looked for her equipment on her own, and ignored Xu Ling.

That’s right, Xu Ling gathered the team members and started to experiment with juicy solar cells.

The principle of juicy solar cells seems somewhat magical to Xu Ling.

It also has an intuitive name - dye-sensitized solar cell.

As we all know, fruit juice contains a natural dye, anthocyanin. Anthocyanin, combined with iodine solution and titanium dioxide, can simulate an activity similar to plant photosynthesis, realizing the conversion of light energy into chemical energy and then into electrical energy.

"Well, let's make a battery first."

Xu Ling did not waste time. The team members had already figured out the principles of the experiment and the method of making the battery in advance.

Ji Yun has always been the main operator for experiment-related operations, and this time is no exception.

It was seen that Ji Yun first fired titanium dioxide, then made a coating with a conductive glass plate, then soaked the coating with fruit juice, added iodine solution, and finally made the counter electrode and assembled it.

A simple solar cell is completed.

"Let's test the voltage first."

Xu Ling reminded.

He was not in a hurry to start the formal experiment at the beginning, mainly because he wanted to see whether the battery was stable.

Everyone agreed and started measuring immediately.

By plotting the relationship between voltage and time on a computer, as well as changing the changes under light, several people found that the voltage was not stable and the current was basically unmeasurable.

More importantly, the voltage changes do not seem to change regularly with changes in light intensity, but instead show a very random jump.

Thanks to Xu Ling for suggesting to check it out, otherwise if we had just carried out the experiment directly, I don’t know how much time and energy would have been wasted.

"What's going on? I don't think there's anything wrong with what we're doing."

Qin Qin looked confused.

"It was obvious that we hadn't made a true solar cell."

Xu Ling hit the nail on the head.

"So where could the problem be?"

Ji Yun asked anxiously.

Yeah, what's the problem?

Xu Ling himself is not quite sure.

Is it the titanium dioxide coating?

Or the choice of juice?

Or is it the electrolyte problem?

Or both?
Although he couldn't think of an answer for the time being, Xu Ling was not discouraged:

“The overall approach should be fine, but the details may not be well grasped.

First, I looked up some information to identify possible problems. Then I designed experiments to try until I could make a real solar cell.

Several people nodded.

However, until the end of today's experiment, Xu Ling and his colleagues had only made some progress in researching the data, and had not made any specific experimental improvements.

The team members said goodbye in a somewhat depressing atmosphere and left the laboratory.

……

"Damn it! Xu Ling! You tricked me so badly!"

Xu Ling had just opened the dormitory door, but before he could take a step out, he heard Yang Chaojie's screams like ghosts and wolves howling.

"What's wrong? You're making such a fuss!" Xu Ling said angrily. "You're asking me what's wrong? You still have the nerve to ask me?"

Yang Chaojie looked at Xu Ling pitifully.

"What happened?"

Xu Ling asked helplessly.

Yang Chaojie didn't say anything, but took out his mobile phone, tapped it left and right, and then held it in front of Xu Ling, as if he wanted to put it directly in Xu Ling's face.

Xu Ling took two steps back before he could clearly see the message on the phone screen:
【(Maodu University Official Account)
Congratulations to Xu Ling, a freshman at our university, for solving the problem of proving the global solution of the incompressible Navier-Stokes equations with small initial values. His research results were officially published in the 2024 issue 22 of Physical Review Letters.

I rely on!

The paper has been published!
"Now do you understand what I'm talking about?" Yang Chaojie asked quietly, "We're all from the School of Physics, so I know what kind of journal PRL is."

"Haha, wasn't I worried that you would feel unbalanced and uncomfortable?"

Knowing he was in the wrong, Xu Ling said awkwardly.

"I feel even worse now, okay? You dare say that about a regular publication?"

Yang Chaojie still couldn't let it go.

"Yeah! But you're really awesome! That's PRL! Many professors may not be able to publish papers."

Qin Kai interrupted and said that he did not dwell on whether Xu Ling had deceived Yang Chaojie.

Xu Ling didn't respond, but just scratched his head and smiled awkwardly.

Yang Chaojie didn't say anything else, and the atmosphere soon calmed down.

……

But how could Xu Ling calm down? He sat in the chair, unable to focus on the experimental materials in front of him.

When Xu Ling thought that his paper might be read, studied and even cited by professors and scholars all over the world, the corners of his mouth couldn't help but rise, and he couldn't suppress it.

Ok……

Is it time to tell my parents the good news?

Xu Ling thought proudly while hurriedly taking out his cell phone.

"Hey! Mom! I have good news for you!"

As soon as the phone was connected, Xu Ling couldn't hide his excitement.

"Well...I'm your dad."

Xu Guoqiang's voice came in a deep voice from the other end of the phone.

"What about my mother?"

Xu Ling asked immediately.

"Can't you just tell me the good news?"

Xu Guoqiang said pretending to be a little unhappy.

Yes, why do you have to tell my mom?

Are you used to it?

Shaking his head, Xu Ling got straight to the point. "Well... well, I wrote a paper and published it in a physics journal. You can take a look. I'll forward the news to you on the school's official account later."

"Is it serious?"

Xu Guoqiang's first reaction was doubt.

Xu Ling suddenly felt hurt. "This is the most authoritative journal in physics! You have to trust your son! Don't keep looking at me the same way you used to."

"Haha, I was just kidding. We are the happiest that you have learned something!"

Xu Guoqiang was extremely excited, his tone full of pride, as if he had published the paper himself.

After that, Xue Yan took over the call. Compared to the thesis, she was more concerned about Xu Ling's life and kept asking about his well-being.

Even though Xu Ling kept emphasizing his thesis, Xue Yan just perfunctorily replied with words like "Okay, okay, I'll definitely go take a look."

Maybe this is the difference in mentality. Compared with success and fame, Xue Yan feels that it is enough for her son to live a healthy and happy life.

However, Xu Ling was only concerned about his own happiness and ignored the external influence of this paper.

A storm is brewing.
