Bai Zhiyuan waited at the entrance of the kindergarten for more than an hour, but still could not see Bai Ya, so he had to leave with regret.

In the kindergarten, Bai Ya is working on a small stove for Jiang Shuang'er alone. There is a children's painting competition in the province recently, and she plans to let Jiang Shuang'er participate.

It must be admitted that Bai Ya has great experience in teaching and educating people, and she has trained Jiang Shuang'er very well.

"Aunt Bai, is that person outside just now your relative?"

Jiang Shuang'er put down the colored pen and raised his head innocently and asked.

She was still young, and when she was at home, she heard Jiang Hua and Su Zhirou talk about Bai Ya. She seemed to understand, but she only knew that Aunt Bai Ya had a long-lost relative who came to her door, but she didn't want to see her.

"Not really relatives, just strangers with blood ties."

Bai Ya smiled lightly, and then pointed out in great detail that there were several imperfections in the application of colors in Jiang Shuang'er's painting just now.

"Aunt Bai, dad said you might have to go on a long journey. Is it true?"

Jiang Shuang'er looked at Bai Ya with some reluctance.

She now spends more time with Bai Ya every day than she does with her parents at home, and has become dependent on her.

"I don't know either. I'm conflicted."

Bai Ya sighed.

She looked at the innocent Jiang Shuang'er and envied her very much. Only children have no worries. When people grow up, they will have many worries.

"Aunt Bai, do you think that if I work hard and win prizes, I can make dad happy?"

Jiang Shuang'er bit her colored pen, rested her chin on her pink arm, and looked sideways at Bai Yawen.

It's not just adults who have worries. Although she is young, she also has her own worries.

She hopes to attract her father through her excellence so that he can stay at home with her more.

"Why do you ask?"

Bai Ya looked at Jiang Shuang'er in confusion.

"Because I found that I have won so many awards, but my father is still very busy every day and rarely has time to accompany me."

Jiang Shuang'er said emotionally.

"Shuang'er, remember, you become excellent not to please anyone, but as the heir to a large group, you must surpass your peers, do you understand?"

Bai Ya looked at Jiang Shuang'er with gentle eyes.

She originally came to the provincial capital just because of an obsession in her heart, but after being in contact with Jiang Shuang'er for a long time, she fell in love with this smart and precocious little girl.

Perhaps because she had gone through hard times in her childhood, she could always see her own reflection in Jiang Shuang'er.

"But, I don't want to be an heir. I just want my father to spend more time with me."

Jiang Shuang'er drooped her little head.

"It's okay, don't you have Aunt Bai Ya?"

Bai Ya held Jiang Shuang'er in her arms heartbrokenly.

At the same time, thousands of miles away in Beijing, Zhao Yanhua probably didn't even expect that after she made a few calls and inquired about graphene, a controversy about materials science was brewing.

A black car parked at the entrance of a secret research institute.

Professor Ni Hong from the Department of Materials Science and Engineering at Peking University got out of the car, straightened out his old-fashioned Mao suit, and walked towards the research institute.

From the outside, this confidential research institute looks like an ordinary scientific research unit. There is no sign on the outside. Even if most people pass by, they don't know what it is about.

"Old Ni, have you made any breakthroughs in the research on semiconductor crystalline silicon? We are waiting for urgent use here."

An old researcher with gray hair, after seeing Ni Hong, immediately pulled him aside and questioned him.

Semiconductor crystalline silicon is an indispensable material in the field of chips. Currently, this material is the most cutting-edge cutting-edge technology even internationally. It is still in the exploratory stage in China.

"It's not that easy. Do you think we can imitate a sample from abroad?"

"You are also engaged in scientific research. You know the basic industrial level, which determines the upper limit of scientific research. Even if we know the principle, the industrial level is not up to standard, and there is no relevant equipment. I am also a clever woman who cannot make a meal without rice."

Ni Hong sighed.

He knew that the research institute was working on a communication satellite project and was currently stuck on chip materials.

"Remember back then, we didn't have CNC machine tools and relied on manual lathes to make submarine propellers? Don't just give up when you encounter difficulties."

The old researcher said angrily.

Although he is wearing ordinary work clothes, his status is extraordinary. He is the deputy director of this secret research institute, an academician-level talent who enjoys special allowances.

"Who gives up? I have no clue about semiconductor crystalline silicon, but I have made a new discovery in another aspect."

Ni Hong argued unconvinced.

During the recent period, in order to study semiconductor crystalline silicon, he spent every day in the laboratory. He almost forgot his granddaughter's birthday. His wife complained all the time, but he was wrongfully dismissed by this old guy Yu Qingsheng. He was really angry.

People.

"Don't mess around. It's not like we haven't tried it before. Currently, we can't find any other materials that can replace crystalline silicon in integrated circuits."

Yu Qingsheng waved his hand, feeling that Ni Hong didn't study semiconductor crystalline silicon properly and was just wasting his time by messing around.

"Don't be so arbitrary. Although this material is still in the theoretical stage, I have calculated the data and it has better performance than silicon in terms of carrier mobility."

Ni Hong said brightly.

Carrier mobility is a professional term in materials science. Whether a material has application prospects in integrated circuits is a very important reference data.

"What material?"

Yu Qingsheng became interested.

At the beginning, in order to study alternatives to crystalline silicon, they tried many other materials, but unfortunately the results were not satisfactory, and the performance could not even match one-tenth of crystalline silicon.

"Graphene, a new material that has not yet been released."

Ni Hong looked around and lowered his voice.

"Since there is no finished product on the market, why are you so sure that this material can replace crystalline silicon?"

Yu Qingsheng frowned subconsciously.

He had never heard of graphene. It sounded related to graphite. Currently, in terms of materials, few people would pay attention to this black stone.

"I have calculated it using formulas. Theoretically speaking, this is a very excellent new material. It is much more reliable than the messy attempts we made before."

Ni Hong came to this conclusion after consulting a lot of information and doing a lot of calculations.

"Honestly, is this graphene secretly revealed to you by your old classmates abroad?"

Yu Qingsheng asked quietly.
