Chapter 247 Graphene, the Material of the Future

Entering the glass door, there is a passage about five meters long.

On the left side of the passage, there is also a glass door. Ding Xiaoyou led his brother Ding Yue in through the glass door on the left.

"Put on your lab coat and go in."

Ding Xiaoyou looked at her brother Ding Yue and warned.

"it is good."

After all, this is an energy chemistry laboratory, and it is still newly built, so it is inevitable to put on a professional lab coat.

A few minutes later, the siblings changed into white lab coats, walked out of the changing room, and pushed open a door from the front.

Immediately, a large room appeared in front of him.

The clean floor, white walls, and the entire room are filled with various chemical-related instruments.

There are instruments and equipment that are very large in size, and there are instruments and equipment that look simple but are actually very useful.

As soon as Ding Yue walked in from the outside, he had the feeling of entering the laboratory of a doctor of chemistry when watching a movie.

It's just that my sister's laboratory obviously has more space and more equipment.

On a console on the right, Ding Yue saw all kinds of glass bottles, some of which contained solid chemicals and some of which contained liquid chemicals.

On the left front is a row of computer consoles.

Obviously, even an energy chemistry laboratory needs a computer to perform related data calculations.

Even this set of computer equipment is included in Nanyang Technological University's 145 million order.

exactly.

Except for the chemical materials, all the equipment in this energy chemistry laboratory was purchased from Nanyang Technological University.

With such a top chemical laboratory in the world, my sister's future development space can be said to be extremely huge.

What she wants to study most is the energy field.

The field of energy related to chemistry, in short, is the conversion of chemical substances into energy power in some way.

In this era of global mechanization, more and more fields are inseparable from energy.

Mobile phones, cars, trains, airplanes, aviation, etc. all require energy.

And human energy is not infinite.

Coal, oil, natural gas, etc. will one day run out.

Therefore, efficient energy use is one of the methods for sustainable development of human beings, unless human beings can master controllable nuclear fusion technology.

However, this seems unlikely.

So what Ding Xiaoyou wants to study is to use advanced technology to make energy use more efficient.

"These devices are the most advanced in the world, I never thought about it before!"

Ding Xiaoyou stepped forward, reached out and touched the equipment beside him.

From now on, these equipments and instruments will be my little friends for experimental research. With the world's most advanced energy chemistry technology experimental research equipment, Ding Xiaoyou may carry out the research related to energy technology that he likes and wants to do most.

"Xiaoyou, after you have this laboratory, what research do you want to do?" Ding Yue turned his head and asked his younger sister Ding Xiaoyou with his brother's loving smile on his face.

"That must be battery energy technology."

Ding Xiaoyou replied with a smile.

"There are thousands of battery-related technologies, is there a clear direction?" Ding Yue continued to ask curiously.

I spent 145 million to buy this set of energy chemistry technology experimental research equipment from Nanyang Technological University, just to let my sister Ding Xiaoyou make good research results in his Wucheng University of Arts and Sciences.

"At present, I have two directions, a fuel cell, and the research and development of hydrogen fuel cells for higher schools." Ding Xiaoyou replied while strolling around his laboratory.

"Hydrogen fuel cells?"

Ding Yue is not very good in chemical energy, but he is good in physics, so he does not understand the hydrogen fuel cell that his sister said.

"It is a power generation device that can directly convert the chemical energy of hydrogen and oxygen into electrical energy.

The basic principle is the reverse reaction of electrolysis of water. Hydrogen and oxygen are supplied to the anode and cathode respectively. After hydrogen diffuses out through the anode and reacts with the electrolyte, electrons are released to the cathode through the external load, understand? "

Ding Xiaoyou explained it professionally.

"Oh, so besides hydrogen fuel cells, what about another one?" Ding Yue nodded, pretending to understand, and then asked another sister, Ding Xiaoyou, about the battery technology that Ding Xiaoyou wanted to study.

But before his sister Ding Xiaoyou could answer him, Ding Yue remembered it.

Because Ding Yue seems to remember that my sister told me about it?

"Is graphene battery technology right?" Ding Yue asked immediately after remembering it.

"Well, graphene batteries are still very marketable in future applications. The most important thing is that graphene batteries can be made very small, such as electrical equipment, mobile phones and computers, and graphene batteries can be used. For hydrogen fuel cells, the field of application has to be larger, such as vehicles."

Ding Xiaoyou nodded and analyzed the application of the two battery technologies in the future if they were researched and realized.

"Graphene battery technology, but graphene peeling technology is not mature enough, then it is difficult for graphene energy storage to support the development of graphene battery technology industry."

Ding Yue still has a certain understanding of graphene battery technology.

The so-called graphene battery is a new energy battery developed by taking advantage of the rapid and massive shuttle motion of lithium ions between the graphene surface and the electrode.

Graphene, considered to be a revolutionary material in the future!

It is a two-dimensional carbon nanomaterial with a hexagonal honeycomb lattice composed of carbon atoms with sp2 hybrid orbitals.

It is obtained by exfoliation from graphite.

Graphite is a very common allotrope of carbon.

Graphene has excellent optical, electrical, and mechanical properties, and has important application prospects in materials science, micro-nano processing, energy, biomedicine, and drug delivery.

What Ding Xiaoyou wants to study is the technical application of graphene in the energy field, that is, graphene batteries.

However.

As Ding Yue just said, the most difficult hurdle in the research and development of graphene battery technology is not the technology itself.

On the contrary, graphene, a material exfoliated from graphite, is very rare.

The energy storage of graphene is not sufficient, even if you develop graphene battery technology, it cannot be widely used.

"Well, the efficient exfoliation of graphene is indeed a big problem."

Ding Xiaoyou couldn't help but pouted and said with a sigh.

Graphene battery technology has broad commercial prospects only when there are sufficient reserves of the material graphene.

"It's okay Xiaoyou, at this stage, isn't there many ways to prepare graphene for thin gifts?"

Because Ding Yue has a certain understanding of graphene, he knows that there are several ways to prepare graphene by exfoliation.

However, these graphene exfoliation preparation methods are difficult to exfoliate and prepare graphene efficiently.

"Yes, at this stage, it is actually possible to use mechanical peeling, redox, SiC epitaxial growth and chemical vapor deposition." Ding Xiaoyou nodded.

"Since there is a graphene exfoliation preparation method, then Xiaoyou can completely optimize the graphene exfoliation preparation method on the existing basis, so that it can achieve the level of efficient exfoliation preparation of graphene."

Ding Yue encouraged her sister.

In fact, the four methods of graphene exfoliation preparation, Ding Yue knows best is chemical vapor deposition.

This is also in line with the field of chemistry that my sister Ding Xiaoyou likes.

The reason why Ding Yue is familiar with chemical vapor deposition is that chemical vapor deposition has certain applications in the semiconductor industry, and the most widely used is the technology used to deposit a variety of materials, including a wide range of insulating materials. , most metal materials and metal alloy materials, etc.

After all, after Ding Yue studied physics for four years in college, he was going to study the field of semiconductor physics. Since semiconductors are involved, Ding Yue must have some knowledge about the application of chemical vapor deposition in the field of semiconductors.

Single-layer graphene was first discovered, and it was actually done by mechanical exfoliation.

The mechanical peeling method does not sound like it is difficult, but in fact, the disadvantage of the mechanical peeling method is obvious, that is, the production efficiency of this method is low, and it is difficult to achieve industrialized mass production.

Although this method of mechanical exfoliation can prepare micron-sized graphene, its controllability is low and it is difficult to achieve large-scale synthesis.

"Okay, then I'll have an interview with chemical vapor deposition to see if I can make a breakthrough in efficiency."

Ding Xiaoyou nodded, but said with great anticipation.

"Haha, old girl, then I'll be waiting for your good news." Ding Yue immediately raised his head and laughed.

"Slightly~"

Ding Xiaoyou rolled his eyes at his brother, and then said: "By the way, I may be able to help you with the lithography machine you mentioned last night."

"yes?"

Hearing this, Ding Yue asked with a faint smile on the corner of his mouth.

In fact, Ding Yue has been waiting for his sister Ding Xiaoyou to say this. After all, he has already given [lithography machine manufacturing technology] to his sister Ding Xiaoyou. If she does not contribute , isn't that for nothing?

"Of course, the research and manufacturing of lithography machines, although the more critical part is in the field of optoelectronics and precision machining, but also involves material chemistry, why, Ding Yue, you don't believe me in material chemistry. talent?"

Ding Xiaoyou put his hands on his hips and said confidently.

"Believe, believe, who are you Ding Xiaoyou, my sister Ding Yue!" Ding Yue nodded quickly and smiled.

"Hee hee, then you beg me, hurry up." Ding Xiaoyou suddenly became naughty.

"Do you want to be beaten?" Ding Yue stepped forward, his palms clenched as big as sandbags.

Unexpectedly, this girl Ding Xiaoyou is not afraid at all, she put her hands on her hips, raised her head and said, "Come on, hit me!"

Uh!

This girl is really capable!

Knowing that if I beat her, my parents would definitely have to give myself a mixed doubles meal with fried pork with bamboo shoots!

Ugh.

In this regard, Ding Xiaoyou, this girl, really pinched her to the death.

"Cut, this principal doesn't compete with children." Ding Yue shook his head and said disdainfully, "Then the chemical technology of the lithography machine will be handed over to you."

Ding Xiaoyou didn't speak, just made an OK gesture.

It's a joke with my brother, but if my brother's Wucheng University of Arts and Sciences has established a lithography machine experimental project, then I will definitely help.

While Ding Yue and his sister Ding Xiaoyou were strolling in this chemical laboratory, on the campus of Wucheng University of Arts and Sciences, Qi Chunsheng, director of the Academic Affairs Office, and Xu Jiuge, the director of Feiyue Animation Studio, were all looking for Ding. Principal, but I couldn't find Principal Ding.

Xu Jiuge called Ding Yue several times, but no one answered.

Ding Yue didn't bring his mobile phone into the chemistry lab because he changed his lab coat, so he didn't know that Xu Jiuge was calling him at the moment.

If Xu Jiuge can't contact Principal Ding, he can only tell the news to An Yujia, CEO of Feiyue Group.

Because Xu Jiuge knew that President Ding had told himself that the distribution of the animated film "Super Marines" was all in charge of Feiyue Media managed by An Yujia.

Xu Jiuge's Feiyue Animation Studio, as the producer, has obtained the film release license issued by the Film Bureau.

As soon as Xu Jiuge heard the news, he was ready to report it to Principal Ding.

As a result, no one knew that Principal Ding's phone call was not answered at all.

So Xu Jiuge came to the administrative building and found An Yujia's office.

"Boss An."

After Xu Jiuge came to An Yujia's office, he walked over and said, "I can't get in touch with Principal Ding for the time being. The film bureau has issued the movie release license for "Super Marines". Regarding the distribution, including It will be troublesome for Mr. An to fix the file and so on."

The reason why Xu Jiuge called Mr. An Yu Jia An was as it should be.

After all, the Feiyue animation studio where Xu Jiuge is located is also part of the Feiyue Group, and An Yujia is the CEO of the Feiyue Group.

In terms of position, An Yujia is indeed bigger than Xu Jiuge.

"Well, I'll be directly responsible for the release of "Super Marines". If the release is finalized, does Principal Ding have a specially designated date?"

An Yujia nodded and asked again.

"Principal Ding meant the National Day file." Xu Jiuge replied.

"If the National Day file is released, it will be released on October 1?" An Yujia doesn't know much about the movie's final release, so let's ask Xu Jiuge for details.

Sure enough, Xu Jiuge shook his head and explained: "Actually, if the National Day file is usually released on September 30, you can choose the time after 5 or 6 pm on September 30, because after the afternoon of September 30, people It's time for the National Day holiday."

"Yes, yes, yes." An Yujia then reacted.

No wonder I have seen a lot of National Day movies before, and it seems that most of them were released on September 30.

Some even offer screenings a few days in advance.

"Why don't we wait until we get in touch with Principal Ding, determine the specific time, and then make the official announcement."

For the sake of safety, An Yujia decided to wait until she contacted Principal Ding and asked for Principal Ding's opinion.

"Well, that's what I mean too." Xu Jiuge agreed, and then chatted with An Yujia about the announcement of the animated movie "Super Marines": "I heard that President An has prepared a lot of "Super Marines" recently. Can the publicity work of "Can Marine Corps"? In fact, Dabai is so popular right now, isn't there a matter of Rentang Medical Technology Group a few days ago, the popularity has always been very high, and basically it does not need much publicity."

Since Xu Jiuge had already finished the animated film "Super Marines" with his team, he finally had his spare time these days and had time to surf the Internet on Weibo, so he was the first to know the incident of Rentang Medical Technology Group.

It has to be said that the fake health robot incident of Rentang Medical Technology Group has once again added a huge wave of enthusiasm to the medical health robot Dabai.

At that time, it was the first full day of the hot search, and there were corresponding hot searches in the following days.

In this incident, there is no doubt that President Ding's Wucheng University of Arts and Sciences and the medical and health robot Dabai were the ones who made a lot of money.

And Xu Jiuge happens to be the person in charge of the animated film about Robot Dabai, so Xu Jiuge must be happy about this incident.

"Well, I know this, so I arranged for some basic announcements of "Super Marines", and the cost is also very low. I don't think it is necessary for large-scale announcements."

An Yujia also nodded.

At this time, Xu Jiuge received a call from Principal Ding's secretary Wen Ruohan.

"Hello, Secretary Wen."

"Sister Jiuge, Principal Ding is back. He just went to the school's energy chemistry laboratory, so he didn't receive your call."

On the phone, Wen Ruohan told Xu Jiuge that Principal Ding had returned.

"Okay, I'll come right over, right in the office?" Xu Jiuge asked.

"Uh-huh."

After hanging up, Xu Jiuge looked at An Yujia and said, "Mr. An, Principal Ding is back."

"Come on, let's go together."

After that, the two beauties walked out of the office together and went upstairs to Principal Ding's office.

Speaking of which, An Yujia is a royal sister, and Xu Jiuge is a young and energetic beauty. When the two walk together, it is also a beautiful landscape.

After Ding Yue returned to the office, he was told by Wen Ruohan that Xu Jiuge had been looking for him and did not answer the phone.

Then he took out his phone from his pocket and looked at it. There were indeed several missed calls from Xu Jiuge.

"Principal Ding, Director Qi from the Academic Affairs Office is also looking for you. After he didn't see anyone in the office, he told me the good news and then went back." Wen Ruohan suddenly showed a smile on his face.

"Oh? Old Qi also has good news?"

Hearing this, Ding Yue couldn't help frowning slightly: "Okay, don't betray me, tell me, what's the good news?"

After Ding Yue learned that Xu Jiuge was looking for him, it was estimated that it should be the review of the "Super Marines" sample, right?

It is very likely that you have obtained a film release license from the Film Bureau. If it is not the case, then the sample review has not passed, and it is called back and needs to be revised according to the revision opinions.

Obviously, Ding Yue believes that Xu Jiuge is looking for him, and he must tell himself about the former, not the latter.

Since Xu Jiuge found himself to have good news to report, then Director Qi is probably also good news.

Because Ding Yue believes that good things come in pairs!

And the smile on Secretary Wen Ruohan's face was too obvious.

If this is not good news, Ding Yue will wash his hair upside down!

Secretary Wen Ruohan always has a happy face when he encounters good news and good things, and stomps his feet in anger when he encounters bad news or something that makes people angry.

She is a simple girl with emotions written on her face.

"Hey hey, it's really good news. Director Qi said that we have applied for the master's degree authorization point applied by Wucheng University of Arts and Sciences!"

Wen Ruohan immediately told Principal Ding the good news!

hiss!

Really good news!

After Ding Yue heard the words, his face also showed a happy look: "Hahaha, this is great news, after we have the master's authorization point, our Wucheng University of Arts and Sciences can train graduate students!"

That's right!

If an undergraduate university does not have a master's degree authorization point, then it is not eligible to have a master's degree.

Ding Yue has already completed four years of university studies, and he can take the postgraduate entrance examination at the end of this year.

If he does not have a master's degree at Wucheng University of Arts and Sciences, then Ding Yue can only be admitted to another university as a graduate student.

There is no doubt that being a graduate student is basically equivalent to working for free for your supervisor while doing research.

Ding Yue didn't want to waste that time and energy.

Therefore, after Ding Yue had the [Master's Authorization Card], he asked the Physics Department of Wucheng University of Arts and Sciences to apply for a master's authorization point.

Then use the above props to improve the success rate of applying for master's authorization points!

Sure enough, I actually applied for it. This is the country's recognition of the master's degree authorization of Wucheng University of Arts and Sciences!

That is to say, from now on, Wucheng University of Arts and Sciences can provide a master's degree certificate for the graduate students of its own school's physics department.

Of course, it is not so easy to get a master's degree from Wucheng University of Arts and Sciences.

In fact, it is not easy for every university to graduate with a master's degree. Every year, there are news that many key universities have reached their postgraduate years and were dropped out of school.

There should not be too many people who can't graduate after being admitted to graduate school.

"Hee hee hee, congratulations to Principal Ding!"

Wen Ruohan said happily.

It is indeed a congratulation for Wucheng University of Arts and Sciences to get the master's authorization point.

Because after the good start of the master's authorization point of physics, it will be relatively easier for Wucheng University of Arts and Sciences to apply for the master's authorization point of other majors in the future.

Moreover, many physics-related majors can actually be listed under the authorization point of the master of physics.

For Ding Yue's Wucheng University of Arts and Sciences to develop better, four-year undergraduate graduates are not enough.

For outstanding students like Tong Yihang and Liu Tiefei, it is obvious that they are too talented just to get a bachelor's degree in mechanics.

The identities of master students and doctoral students are what Tong Yihang and Liu Tiefei should have for outstanding students like them!

However, if Wucheng University of Arts and Sciences wants to have a doctoral authorization point, it is not very difficult.
