Scholar’s Starry Sea

On the first day when he returned to the University of Science and Technology, Wu Bin was quickly called to the office by Director Jiang and asked him to prepare for graduation.

"Ah, is it so fast?" Wu Bin thought there would be a buffer period or something, but he didn't expect Director Jiang to tell him about graduation when he just came back.

"What's so procrastinating about this, and I mean you can start writing your graduation thesis, do you think it will be fast?" Director Jiang asked Wu Bin.

"This is not true." Wu Bin shook his head.

"Then you should hurry up and start preparing." Director Jiang added: "But don't think you can just write a business appointment because you are ready to graduate."

"Of course not." Wu Bin shook his head quickly.

"Well, I believe you are not the one who can do this kind of thing, then you go and work on yours."

With the question of what topic to choose as the graduation thesis Walking all the way back to the laboratory, Wu Bin was about to change his clothes. He heard Feng golden brilliance call him and said: "The person from the scientific research department was looking for you two days ago. I said you were not there, so he left a phone call. Me."

"People from the scientific research department are looking for me?" Wu Bin asked very unexpectedly.

The Department of Scientific Research, the Department of Science and Technology Archaeology, is a very distinctive department of the University of Science and Technology. It uses modern technology to analyze ancient remains to obtain a wealth of potential information, combined with archaeology Methods to explore human history.

'But I don’t seem to have had any communication with people in this department...'

But since everyone is looking for them, maybe they are looking for him in an urgent matter, so Wu Bin picked up the phone and called the other party.

On the first day back to the University of Science and Technology, Wu Bin was quickly called by Director Jiang to the office and asked him to start preparing for graduation.

"Ah, is it so fast?" Wu Bin thought there would be a buffer period or something, but he didn't expect Director Jiang to tell him about graduation when he just came back.

"What's so procrastinating about this, and I mean you can start writing your graduation thesis, do you think it will be fast?" Director Jiang asked Wu Bin.

"That's not true." Wu Bin shook his head.

"Then you should start preparing as soon as possible." Director Jiang added, "But don't think you can just write a business appointment because you are ready to graduate."

"Of course not." Wu Bin shook his head quickly.

"Well, I believe you are not the one who can do this kind of thing, then you go and work on yours."

He heard Feng golden brilliance call him and said: "The person from the scientific research department was looking for you two days ago. I said you were not there, so he left a phone call. Me."

"People from the scientific research department are looking for me?" Wu Bin asked very unexpectedly.

The full name of the Department of Scientific Research is the Department of Archaeology of Science and Technology. It belongs to the University of Science and Technology and is a very distinctive department. It uses modern technology to analyze ancient remains to obtain a wealth of potential information, combined with archaeological methods. Come to explore human history.

'But I don’t seem to have had any communication with people in this department...'

But since everyone is looking for them, maybe they are looking for him in an urgent matter, so Wu Bin picked up the phone and called the other party.

"Hello, who is it?" A man's voice came to mind on the other end of the phone.

"Hello, I’m Wu Bin, I heard from Master Old Feng that you came to me?"

"Oh! Wu Bin, yes, I’ve been to you , But it’s not very convenient on the phone. How about we go to the volute to talk?"

"Russia... OK."

So Wu Bin stepped on it inexplicably After getting on the bicycle, I soon came to the door of Volute Time Restaurant.

"Here, Wu Bin classmate."

As soon as Wu Bin parked his car, he saw a boy with glasses moved towards him and waved at the entrance of the restaurant.

"Hello, are you looking for me?" Wu Bin walked over and asked.

"Yes, first introduce myself. My name is Xie Hui. I am an Academician student in the Department of Science and Technology Archaeology. The way I approached you this time was a bit reckless. Please forgive me."

"Oh, oh, it’s okay, it’s okay, so you are looking for me to...?"

"Let’s go in and talk again."

Xie Hui gave Wu after entering the restaurant Bin ordered a Coke, and sat across from him with a cup of milk tea.

"Then I'll just say straight to the point." Put down the milk tea and Xie Hui looked at Wu Bin and asked: "I wonder if you know anything about murals?"

" What kind of mural?" Wu Bin asked.

"Architectural murals, grotto murals, and tomb murals and so on."

"Oh, have you heard of it, and then?"

" You should know that there is a lot of information recorded in the murals and they are a valuable asset in the history of human social development. From the murals at the Shimao site 4200 years ago to the Tang, Song, Yuan, Ming, and Qing dynasties, tomb murals have been found."

"Especially Tang Dynasty! Regardless of quantity and quality, it is very good!" Xie Hui's tone was suddenly impassioned.

Wu Bin continued to listen patiently while drinking Coke.

"But now we are facing a very troublesome problem, that is, a large number of tomb murals have many diseases and urgently need to be repaired. Recently, our research has found that graphene plays an important role in the protection of murals. !"

'Oh~'

Speaking of this, Wu Bin finally understood a little bit of the reason why Xie Academician came to find himself.

Seeing Wu Bin’s clear expression, Xie Hui went on to say: “Because the structure of the mural from the outside to the inside mainly includes the paint layer, the white gray layer, the grass mud layer and the brick wall layer.”

"The main component of the white gray layer is calcium carbonate. So over time, the white gray layer is prone to failure, resulting in damage to the surface of the mural, so it is in urgent need of protection."

" Don't take protective measures?" Wu Bin asked curiously.

"Of course, there are also protective measures. At present, the protective materials for murals are mainly divided into two categories: organic and inorganic materials. However, the compatibility of organic protective materials with the mural itself is too poor, and it is easy to age after long-term use. , And even become brittle and yellow, this is not what we want to see."

"At the same time, because the membrane formed by organic materials is not breathable, the mural will eventually swell and chalk. You must know that this pair of murals Said it is an irreparable fatal injury!"

"Oh~" Wu Bin continued to be nodded, and took out a booklet from his pocket and started taking notes.

Seeing Wu Bin taking notes, Xie Hui seemed a little surprised, but he still admired more, so he slowed down a bit and said: "Compared with organic materials, inorganic materials like hydrogen Calcium Oxide The protective material has the advantages of good compatibility and aging resistance."

Looking at Wu Bin quickly writing down a few lines, Xie Hui went on to say: "When applied to the surface of the mural, the hydrogen Calcium Oxide will It reacts with carbon dioxide in the air to form calcium carbonate and fuse together with the white ash layer, thereby further improving the strength of the white ash layer and playing a better protective effect."

"en? That's not a problem. Has it been resolved?" Wu Bin asked, looking up.

"If it's so simple, I won't have to look for you so eagerly. The ones I just mentioned are just the papers published by Kepron in 2000. He wrote in the paper that if you use nano-hydrogen Calcium Oxide protects the murals. Due to the nano size effect, the Chemistry and Physics characteristics of hydrogen Calcium Oxide will change, and the surface activity and stability will be greatly increased, and the protective effect will naturally be significantly improved."

"However, this idea is actually difficult to put into practice...oh no, there are many difficulties."

After lightly coughed, Xie Hui took a sip of milk tea and continued: "Since the publication of this paper, inorganic Nanomaterials have always been the new research direction of mural protection materials. However, we have tried the aqueous solution method, alcohol solution method, microemulsion method and calcium metal method to synthesize nano-hydrogen Calcium Oxide, but unfortunately none of them work."

Xie Hui sighed then said, "These synthetic hydrogen Calcium Oxide are not only too large in size, but also have disadvantages such as poor permeability, poor stability, difficult to purify, complex operation, and high cost."

Wu Bin couldn't help but roll his eyes when he heard this. Isn't this the legendary uselessness...

Looking at Wu Bin's speechless expression, Xie Hui smiled awkwardly and continued: "But our research is not nothing."

"We found that the slow carbonization and low reinforcement strength of Hydrogen Calcium Oxide have not been effectively solved. The fundamental reason is that the hydrogen Calcium has not been clarified. The kinetic law of Oxide nucleation and growth makes it difficult to achieve effective breakthroughs in key technologies such as nano-hydrogen Calcium Oxide controllable preparation."

Hearing this, Wu Bin was somewhat nodded and began to think about it. Calculate this information.

"What happened later?"

"Oh, now our research group has proposed a new idea, we want to introduce graphene Quantum points to solve this problem."

Hearing this, Wu Bin snapped his fingers suddenly and said: "You want to use the confinement effect of the graphene Quantum surfactant to control the nucleation growth kinetic rate of hydrogen calcium oxide?"

Xie Hui was dumbfounded when he heard the whole person, with his mouth open, he didn't know what to say. After a long time, he swallowed with difficulty and said: "I knew it was right to find you!"

"We just want to achieve the controlled synthesis of hydrogen Calcium Oxide nanomaterials!"

"So you want to work with me on this project?" Wu Bin asked.

"Yes, I have read two papers on graphene preparation you published, and found that your ideas are completely possible to solve our current difficulties, so I very much hope that I can get your help."

"Okay, I will join your group!" Wu Bin nodded and said.
