The thoughts along the way also made Shang Yiyun understand something, but now that he has come to the classroom, he will no longer continue to think about nuclear energy.

Before the successful research of graphene vanadium oxide batteries, he was ready to rest for two days, but now it seems that the effect is not good.

On the way to the classroom just now, he was still thinking about the problem in his head, so it seemed impossible for him to take a break.

However, saying goodbye to experiments in a short period of time can also be said to be an alternative break.

After coming to the classroom, Shang Yiyun sat down where the previous class was, and then put the book on the table.

The two classes this morning were professional classes, and the teacher of this course was a middle-aged woman, just as he was recalling.

A middle-aged woman walked in, who was the teacher of the course.

At this time, Shang Yiyun didn't expect that he was thinking about the other party in his heart, but he didn't expect the other party to come to the classroom.

In response to this situation, he no longer continued to think, but opened the book on the table and prepared to read it.

As soon as I opened the book, the class bell rang, and the whole class stood up and said hello to the teacher in unison.

The teacher of this course said, "Hello students, please take a seat."

It indicates that the class has officially entered the class, and now there is more than a month before the summer vacation, and the course is already 70% in progress, so it is not a big problem to learn all the content before the summer vacation.

Of course, the learning progress of this course has little to do with Shangyiyun, because his learning progress has reached 100%.

The teacher didn't believe it before, but after the test, he had to believe it.

In the morning, except for chatting with other people after class, he would read a book or think about problems with his cheeks on his hands.

Since he decided to take a two-day break, the question he pondered in his heart naturally had nothing to do with research, but about the company to be registered and the future development prospects.

Now that the graphene vanadium oxide battery has been successfully developed, he wants to enter the new energy vehicle battery market with this research result, but if he wants to gain a foothold in this market, he must have other scientific research results.

From this point of view, it is very necessary to develop another kind of graphene battery before the summer vacation, and all this can only be obtained through his efforts.

Thinking of this, Shang Yiyun had a sense of urgency in his heart, but he also knew in his heart that there was still more than a month before the summer vacation, so he was not in a hurry for these two days.

Moreover, he has already written the plan of the experiment, and after two days, he can directly devote himself to the research, and the rest now is only to prepare for the future research, and in the process of research, it is very important to have a good mental state.

Thinking about things related to the company, Shang Yiyun also suddenly remembered that he had not contacted Feng Yuting for many days, and he didn't know if the preparations before the establishment of the company were still in place.

He was going to find a time to contact Feng Yuting to get the latest information.

However, he is still in class, and he will not call Feng Yuting directly in class, but is ready to wait until after school to contact the other party.

In this way, time passed slowly, and finally waited for the school bell to ring, and he ran out of the classroom directly, because it was relatively close to the door, so he was the first to leave the classroom.

After leaving the classroom, Shang Yiyun went directly to the place where things were printed, and he was going to print out the experimental plan he had written yesterday, and then hand it over to Cao Xun and Zhang Liu.

Yesterday he had already told the two of them about it, and agreed on a place to meet, and now there were still ten minutes before the agreed time, and there were not many people in the main printing shop, which was enough.

When he came to the school print shop, he found that there were not many people in the store, seeing this situation, Shang Yiyun breathed a sigh of relief, before he came, he was really worried that there were a lot of people in the print shop, and he still needed to queue up to print.

But now it seems that this worry is obviously unnecessary, take out the USB flash drive from your pocket, come to the computer, copy the files in the USB flash drive to the computer desktop, and then set the printing format and start printing.

There were 6 copies of a document and two copies printed, so a total of 12 sheets were printed, and after the money for the printed documents was settled, he left the print shop.

It was now five minutes away from the agreed time, and the place was not far from where he was now, and it was only a two-minute walk to get there.

Shang Yiyun wasn't sure if the two of them had waited there in advance, but thinking of this, he still quickened his pace, and the original two-minute journey only took a minute and a half.

When he came to that place, he really found Cao Xun and Zhang Liu, and in the face of this situation, he spoke directly.

"Cao Xun and Zhang Liu, I didn't expect the two of you to come here in advance, but I wasn't late. ”

After saying this, Shang Yiyun paused for a moment, and then handed the two documents in his hand to the other party.

"These two documents are the experimental protocols I wrote, you go back and take a good look at them, so that the experiment after two days, you don't need to make any preparations, and you can start the experiment directly. ”

At this time, Cao Xun and Zhang Liu took the document, glanced at it casually, and had a general idea in their hearts.

The documents have been delivered to the hands of the two of them, Shang Yiyun is ready to leave here, and he will call Feng Yuting later, so naturally he will not contact Feng Yuting in front of Cao Xun and Zhang Liu.

After saying goodbye to the two, Shang Yiyun found a quiet place on campus and dialed Feng Yuting's phone.

Suddenly I heard a beeping sound, which did not disappear until the phone was connected.

"Yi Yun, call me at this time, is there anything you want to tell me?"

As soon as the phone was connected, Feng Yuting's voice came, and the voice was very good, but Shang Yiyun also knew in his heart that he was not calling the other party to listen to the other party's voice.

"Sister Yuting, I called you this time, just to ask about the recent situation, by the way, I have led the team to research the graphene vanadium oxide battery, I just applied for a patent a few days ago, and after the patent comes down, the time to set up the company is almost the same. ”

On the other side of the phone, Feng Yuting heard Shang Yiyun's words, and she agreed in her heart, they had enough time to prepare, and it was time for the company to be born, and when the company was established, she was ready to show her skills.

"Well, Yi Yun, I haven't been idle during this time, I've been watching the market, so that when the company is officially established, I can use it. ”

From Feng Yuting's tone, Shang Yiyun felt a strong sense of confidence, and he was also happy about this situation.

Anyway, everything is on track, and all the preparations for setting up the company have been made.

In the following time, the two chatted about some things related to the company and hung up the phone.

However, Shang Yiyun was going to make a phone call to Xu Feng and tell the other party about the current situation, Xu Feng was now his ally, so he naturally had the right to know.

Thinking of this, he dialed Xu Feng's phone, and after a short time of waiting, the phone was connected, and Xu Feng's voice also came.

"Yi Yun, you call me now, is there anything wrong?"

Xu Feng's voice was full of doubts, as if he didn't understand why Shang Yiyun called him at this time.

"It's not a big deal, I just want to tell you that I have successfully researched graphene vanadium oxide batteries, and Feng Yuting is ready to do so, and it is not far from the establishment of the company. ”

Shang Yiyun said lightly, but Xu Feng was not so calm, and after hearing these words, he reacted more violently.

"It's not a big deal, doesn't it have to be the end of the world?"

Different from Shang Yiyun's indifference, Xu Feng's face was very exciting at this time, he didn't expect that Shang Yiyun would research graphene vanadium oxide batteries in such a short period of time.

"Okay, I also know about this matter, if there is nothing else, then hang up the phone first, and then contact later. ”

At this time, Shang Yiyun heard that the other side of the phone was a little messy, and he understood.

"There's nothing else to say now, since you've got something going on there, hang up the phone. ”

After saying this, Shang Yiyun hung up the phone.

The things that should be said have been said, and the things that should be done have been done, and for a while, Shang Yiyun didn't know what to do.

Because there are still classes in the afternoon, he doesn't want to leave Kyoto University, and now it seems that he can only wander around the campus casually, go to Huaguo Normal University at noon, and go to Chen Feiyun for lunch.

Thinking of this, his body moved again, and now his goal was to wander around Kyoto University, the campus of Kyoto University is not small, and it took ten minutes to walk around.

It was already half past ten in the morning, and he was going to go directly to Huaguo Normal University, because he didn't know whether Chen Feiyun was in the dormitory or in class, so he called the other party on the way to inquire about the situation.

"Fei Yun, where are you now, do you have any classes?"

Now that the other party has connected the phone, Shang Yiyun already has the answer in his heart, and the other party is not in the classroom now.

"I'm in the library now, what's the matter?"

Hearing Chen Feiyun's answer, Shang Yiyun laughed and did not answer, but asked the exact location, ready to surprise the other party.

Thinking of this, Shang Yiyun accelerated his pace, striving to reach the library of Huaguo Normal University as soon as possible.

When he came to the library, he didn't stop too long and went directly to the place where Chen Feiyun was.

It didn't take long for Shang Yiyun to see Chen Feiyun's figure, come directly to the other party's side, and patted the other party's shoulder.

Chen Feiyun was like a frightened deer, almost jumping up, but when she turned around and saw Shang Yiyun, she directly forgot what had just happened.

"Yi Yun, when did you come here, why didn't you tell me in advance. ”

This sentence seems to carry a hint of grievance, but also a kind of surprise.

"I want to give you a surprise, if I told you in advance, how can it be called a surprise. ”

Shang Yiyun had a smile on his face and said softly.

"Hmph, no matter what, you scared me just now, so you have to compensate me, as for how to compensate, I haven't thought of it for the time being. ”

At this time, Chen Feiyun said a word arrogantly.

Faced with this situation, Shang Yiyun felt a little funny, but he still agreed. "Okay, I'll talk about it when you think about it. ”

Since it is now in the library of Huaguo Normal University, Shang Yiyun naturally will not waste this opportunity, so he told Chen Feiyun a few books and asked the other party to go to the library to borrow these books.

As for him, he sat in a position and waited, and the few books that Shang Yiyun had borrowed could not be found in the library of Kyoto University, and he also inadvertently searched for these books in the library of Huaguo Normal University.

After waiting like this for a while, Shang Yiyun saw Chen Feiyun walking out of the library with a few books in his hand, and it seemed that he had borrowed the books he wanted to read.

Faced with this situation, a smile appeared on his face.

"Yi Yun, take a look, these books are not the books you said. After saying this, Chen Feiyun handed the book to Shang Yiyun and waited for a reply.

looked at the title of the book, then opened the book and glanced at it, he was sure that these books were the books he wanted to borrow, it was not yet noon, he was going to read the books here, thinking of this, Shang Yiyun told Chen Feiyun his thoughts.

Chen Feiyun had no opinion, so Shang Yiyun found a place, put the book on the table, and then began to read.

These books are related to biomass energy.

Biomass refers to various organisms produced by photosynthesis through the use of atmosphere, water, land, etc., that is, all living and growing organic matter is commonly known as biomass, which includes plants, animals and microorganisms.

At the beginning of reading, it is the concept of biomass energy, for this part of the content, Shang Yiyun took a brief look, and then continued to read the other content.

There are three main ways to utilize biomass energy: direct combustion, thermochemical conversion and biochemical conversion.

The direct combustion of biomass will still be the main way of biomass energy utilization in China for a long time in the future.

At present, the transformation of traditional fire-burning stoves with a thermal efficiency of only about 10%, and the promotion of fire-saving stoves with an efficiency of up to 20%-30% are simple, easy to promote, and energy-saving measures with obvious benefits, which are listed as one of the key tasks of rural new energy construction by the state.

The thermochemical conversion of biomass refers to the technology of vaporizing, carbonizing, pyrolysis and catalytic liquefaction of biomass at a certain temperature and conditions to produce gaseous fuels, liquid fuels and chemical substances.

The biochemical conversion of biomass includes biomass-biogas conversion and biomass-ethanol conversion, etc., biogas conversion is an organic matter in an anaerobic environment, through microbial fermentation to produce a flammable mixed gas with methane as the main component, that is, biogas.

Ethanol conversion is the fermentation of raw materials such as sugar, starch and cellulose to produce ethanol.

These are the ways of using biomass energy, and biomass energy is the most important in renewable energy, but the degree of industrialization is the worst.
