Siheyuan: I have a mysterious factory

What surprised him was that carbon could replace metal?

Thinking of this, he was not only a little excited.

Because the storage capacity of carbon far exceeds that of metal.

Best of all, carbon is cheap and renewable.

Burning wood and straw can produce relatively pure carbon.

If we can really develop this aspect.

After that, domestic technology should not take off?

Thinking of this, Ma Jie showed excitement on his face.

"After that, I specialized in special carbon materials." Ma Jie also determined his own research direction.

Looking at Ma Jie, Xu Dajun spoke again.

"For carbon, you have to try to reduce its size, and then rearrange it, and new properties will appear." Xu Dajun continued.

Hearing this, Ma Jie nodded heavily.

"Also, for other substances, if the particle diameter of the substance is reduced to a certain extent, it will also show different properties." Xu Dajun added.

What he said has tended towards nanotechnology.

Of course, this technology was not proposed until 1980.

Later, many achievements were made.

Ma Jie was thoughtful when he heard these words.

"To what extent do you want to shrink?" Ma Jie asked.

"For carbon, as long as it is reduced to the micron level, the effect can be seen. Most other substances need to be reduced to the nanometer level." Xu Dajun explained with a smile.

"Ah?!!" Ma Jie, who was full of confidence just now, was instantly dumbfounded.

What is the concept of micron?

One millimeter is divided into one thousand points, which is one micron.

To pulverize matter to such an extent...

He didn't dare to think about the difficulty.

Microns are so hard, let alone nanometers.

A nanometer is 1/1000 of a micron.

Suddenly, Ma Jie felt hopeless.

"Take your time, our satellites have been launched into the sky, are you still afraid of this?" Xu Dajun comforted.

"Yeah." Ma Jie nodded with a bitter face.

Looking at the time, I have been here for several hours.

Xu Dajun chose to leave and left here.

Seeing Xu Dajun leave on a motorcycle, Sun Qingyuan and Ma Jie were shocked.

"The boss is a bull, and the motorcycles are here, amazing!"

Xu Dajun didn't go back directly.

He walked around the city.

Because of the development of the textile industry.

There are also many new clothes now.

Xu Dajun wanted to buy some for his parents.

I picked out some trendy clothes and bought a few catties of candied fruit.

Xu Dajun rushed to his parents' house.

"chug chug...

this era.

Ride a motorcycle.

Definitely something super cool.

Not only the return rate is [-]% on the road.

Even when they come to the door of their parents' house, the children will come out to watch the excitement when they hear the noise.

Looking at Xu Dajun's motorcycle, several children ran behind.

When Xu Dajun came to the alley, he was relieved to see that there were no cars.

Then, he rode to the door and walked in.

"Dad, Mom, I'm back." Xu Dajun shouted.

Neighbors in the neighborhood stuck their heads out when they heard the shouts.

"The army is back, you haven't been here for a long time."

"Dajun, take some time to sit down, you didn't come here during the Chinese New Year."

"Xiaojun, I saw you on TV just now."

.....

Everyone was very enthusiastic.

inside the room.

Uncle Zhang heard the shout and glanced at Father Xu.

"The army is back, don't you go to greet him?" Uncle Zhang was a little surprised.

If his child is so powerful, he will definitely lead him to show off everywhere.

Moreover, a few days ago, Xu's father didn't often brag in front of them.

Why now that Xu Dajun is back, he is not excited.

"Old Xu, Xiaojun is back." Aunt Li said.

"With you as a father? You don't even welcome such a promising child back?" Aunt Qiu was also a little dissatisfied.

Father Xu gave them a disdainful look.

"Don't make excuses, everyone wants to run away, but I'm one of them." Xu's father said excitedly.

After losing so many times, it's always my turn to win.

Aunt Qiu looked over.

"What are you looking at? Playing tricks?" Father Xu pushed her away.

"I don't believe that your poker skills are so bad, you can clear all 747 colors and return a dragon." Aunt Qiu was full of disbelief.

"Believe it or not." Xu's father was even more number one.

While talking, Xu's father began to draw cards.

Seeing the cards in his hand, he was overjoyed.

"Touch yourself!" Father Xu yelled.

As a result, at this moment, a rag fell on the table.

"Old man, your son is here and you still hit him. Believe it or not, I'll burn it for you later." Mother Xu said angrily.

This rag directly messed up the mahjong tiles.

Father Xu's hand stopped in the air and could not come down.

"Stop playing, hurry up and take care of the children, Xiaojun is so promising, he is not as good as you as a father." Aunt Qiu said righteously, pushing the cards with both hands.

The other two also seized the opportunity and took the opportunity to mess up their own cards.

"We're busy first, and we're going home for dinner." Uncle Zhang and Aunt Li also said.

After speaking, he stood up and walked outside.

Xu's father glared at Xu's mother, the corners of his mouth twitching.

At this moment, Xu Dajun opened the door and walked in.

"Mom and Dad, I'm back." Xu Dajun said happily.

"What are you doing when you come back? Why are you hugging your grandson? If you can't hug your grandson, you'd better not come back." Xu's father said angrily.

Xu Dajun was stunned, he had never seen his father so angry.

It feels a little strange.

"You old man, why are you taking your anger out on your son when you lose the card?" Mother Xu said dissatisfied.

Hearing this, father of Xu's eyes were filled with tears.

"All one color and one dragon! It's hard for me to win, but in the end..."

Full of grievances, nowhere to vent. .

Chapter 180 Second, as a father's little thought, Huaxia once again exerts its strength in the alloy industry

Hear what my mother said.

Xu Dajun understood what happened, and a smile appeared on his face.

"Dad, lost again?" Xu Dajun knew his father's skills.

"Lose, lose, lose, you know you lost!" Xu's father was very angry.
