The opening sign-in starts from the research institute

Chapter 6 Sign-in, low-cost mass production of ultra-large graphene

Chapter 6 Sign-in, low-cost mass production of ultra-large graphene

Mao Tingjie went straight back to the house, and Fang Cheng hugged Zhao Xiaoqi and began to chew.

After a while before giving up, Zhao Xiaoqi blushed and said coquettishly, "Pay attention to the influence, this is in the restaurant!"

"It doesn't matter if it's not a restaurant?" Fang Cheng laughed.

Zhao Xiaoqi rolled Fang Cheng's eyes.

Ten minutes later, Fang Cheng returned to the office.

The research institute, especially for a new private research institute like Fang Cheng, lacks money the most. With the injection of 100 million, the urgent need is finally solved.

How to use this money wisely is the most critical thing right now.

"With this 100 million, there is no need to worry about reducing the progress of the experiment due to the experimental consumables."

"However, research and development requires a team. Although I can do it alone, the efficiency will inevitably decrease. In terms of recruiting talents..." Fang Cheng has a headache. The old problems are temporarily solved, and he has to face new problems.

"Although there are several double-first-class universities in Xingcheng, and there are many doctoral programs, the reputation of Xinghe Future Research Institute is not the same as when I first came back two years ago."

"At that time, relying on my double doctorate title of Xiacheng University, I also used my teacher's reputation to recruit some people, but now, there is no result in two years..." Fang Cheng shook his head. The previous reputation has dissipated. In the academic circle, although it is not possible to see myself as a joke, it is certain that the Galaxy Future Research Institute has a bad reputation.

"Those who want to come have no ability, those who have ability don't want to come..." Fang Cheng thought for a while, but stopped thinking about it. Money is the foundation for the development of a research institute. Without money, you can't do it, but you can't do it if you have money.

For a research institute to truly take shape, much, much is needed.

"I haven't used the sign-in today, so sign in first to see." Fang Cheng immediately called the system in his heart.

"Sign in!" Fang Cheng thought to himself.

next moment!

"Ding! Congratulations to the host. After completing three consecutive check-ins, the newcomer period is over, and the reward bonus will be cancelled. At the same time, multiple sign-in opportunities will be opened to integrate the sign-in method. Multiple sign-in integration will give you a greater chance to get better rewards. (Note, Currently, a maximum of ten opportunities can be accumulated.)”

"Ding! Congratulations to the host, you have obtained a low-cost mass production method for ultra-large graphene!"

The next moment, Fang Cheng didn't even have time to be pleasantly surprised, he sat stiffly on the chair, a lot of knowledge poured into his brain, until half an hour later, a new low-cost preparation method for large-area graphene was fully poured into it. In Fang Cheng's mind, not only the infusion of knowledge, but also the development and testing process of this technology were also loaded into Fang Cheng's mind.

It seems that this experiment is Fang Cheng's countless attempts, groping out bit by bit, and the foundation is very solid.

After more than an hour, Fang Cheng slowly woke up, his eyes filled with disbelief, and at the same time, he opened his palm, and there was a USB memory in it.

"It's unbelievable, what is this little game, the huge knowledge that suddenly poured into my mind, and how did this USB drive appear?" As a researcher, the first reaction when encountering unknown events is to use logical thinking to solve them All of this, however, faced with such a system, Fang Cheng was a little powerless.

However, none of this matters anymore.

After patiently copying all the data in the USB flash drive to the confidential computer, the USB flash drive slowly decomposed itself in front of Fang Cheng's eyes, and even the dust could not be found.

Fang Cheng was shocked again, but right now, these are no longer important.

Even Fang Cheng can no longer sit here in the office and make any schedule arrangements, the results are all out, and he is still talking about budget arrangements!

As a researcher specializing in graphene, there is nothing more worthy of attention than this new manufacturing method.

Graphene material has excellent performance in many fields, and it is known as the king of materials in the 21st century.

Its excellent optical, electrical, mechanical, and thermal properties have prompted researchers to continue to study it in depth.

Therefore, the research and application of graphene has continued to heat up in recent years. Graphite and graphene-related materials are widely used in battery electrode materials, semiconductor devices, transparent displays, sensors, capacitors, transistors, etc., with great prospects.

For example, in terms of semiconductor materials alone, replacing silicon with graphene as a new material can not only break through the physical limit of silicon semiconductors, but also have stronger performance.Even at the same process level, graphene chips will theoretically improve the performance of silicon semiconductors by at least [-]%.

In today's all-round rise of the Xia Kingdom, the chip field is still in a weak position internationally, and the country often faces the embarrassing situation of chips being stuck.

The graphene-based chip can be said to be an important node for Xia Guo to achieve cornering overtaking in the chip field.

From this alone, the importance of graphene materials can be imagined.

Today, one of the main obstacles that restricts the expansion of the application of graphene in these fields is that the cost is too expensive. Many manufacturers say that they already have low-cost mass production of graphene, but, in fact, its content is indeed some graphene-like materials in essence. Graphene, or multi-layer, or even graphene with more than ten layers, is not really the most needed single-layer graphene material at all, and at the same time, the area of ​​the prepared single-layer graphene is too small.

Even now in 2028, the real large-area single-layer graphene is still costing thousands of square meters per gram, or even tens of thousands of square meters per gram.The high price is the biggest obstacle restricting the wide application of graphene's excellent properties.

Fang Cheng regards solving this problem as the first key problem of their research institute.

But right now, with this preparation method in his mind, Fang Cheng couldn't help breathing quickly when he thought of the almost outrageously low price.

"The plan is very perfect and the feasibility is very high!"

"We must go to the laboratory for verification first. We must, we must go! We must go now."

Fang Cheng ran to the laboratory in a hurry, took out the key in a hurry, and inserted the keyhole several times before inserting the keyhole, opened the door, walked in quickly, came to the material rack, Fang Cheng counted what he needed one by one materials and equipment.

"The number of test tubes is low!"

"Not enough chemicals!"

"The outlet is too small, it needs to be replaced!"

"The intensity of ultrasonic radiation is not enough..."

……

Fang Cheng was in a hurry to verify the new preparation method, but he had to be patient and edit a bill of materials on his mobile phone. The new graphene preparation method used the redox route.

It is also the preparation route that Fang Cheng has been studying in depth, the redox route, among the many methods for preparing graphene today, is the most likely to achieve low-cost, large-area industrial route.

The redox route is divided into three steps, oxidation, stripping, and reduction.

The most critical of this new preparation method involves a key new oxidizing agent, reducing agent, as well as the dosage ratio and temperature control of the oxidizing agent and reducing agent.

After less than half an hour, Fang Cheng finally sorted out all the materials and equipment, took them to the door, and ran all the way to Zhao Xiaoqi's office.
