"Xiao Zhang, you turn off the graphene instrument and go back! There's nothing going on here! Liu Jianguo took off his white coat and prepared to get off work.

He knew that Zhang Wenxuan was Zhang Wenkai's younger brother, so he also took good care of it, and he didn't look good at Zhang Wenxuan at first, after all, he was a student who had not yet left school, and what kind of ideological values could he have.

However, after contact, he found that it was not what he thought, and it may have been due to the difficult life of his childhood, which created Zhang Wenxuan's character of cherishing everything in front of him.

Even if Zhang Wenxuan doesn't work in his life, his brother Zhang Wenkai can guarantee that he will not have to worry about food and clothing, and he still has a lot of pocket money in his hands.

But even so, Zhang Wenxuan does not waste a grain of rice or throw away a single vegetable, which is also what impresses Liu Jianguo.

Their era was an era of not enough food and clothing, so they valued the quality of people.

"It's okay, Uncle Liu, if you have anything to tell me, I'll do it for you!" Zhang Wenxuan touched his head and said.

Liu Jianguo smiled and said, "You are much more diligent than your brother." "He stays in the laboratory every day to do research, and he knows that Zhang Wenkai basically does not come to the laboratory to inspect, which is completely the rhythm of your work.

In this quality, Liu Jianguo feels that Zhang Wenkai is not as good as Zhang Wenxuan.

Zhang Wenxuan's face turned red, and he touched his head and was embarrassed.

"Who's speaking ill of me?" Zhang Wenkai's voice sounded.

"It's really Cao Cao, Cao Cao is here!" Liu Jianguo shook his head and laughed.

"Brother!" Zhang Wenxuan also nodded.

Zhang Wenkai walked in front of Liu Jianguo, then turned around and winked at Zhang Wenxuan, meaning whether his work was smooth or not.

Zhang Wenxuan's face smiled a flower, and he nodded to Zhang Wenkai vaguely.

Since Zhang Wenxuan and Liu Jianguo got along very well, Zhang Wenkai also put his mind at ease, so he turned to Liu Jianguo and asked, "Do you know a material called nickel phosphorus?" ”

Liu Jianguo's main focus is on materials science, it is impossible not to know nickel-phosphorus alloys, he frowned, I don't know why Zhang Wenkai mentioned nickel-phosphorus alloys? It seems that this alloy is not very useful.

As we all know, nickel-phosphorus alloy has always been used in electroplating, and tools commonly used in life or tools with large wear and tear will basically use the method of electroplating nickel-phosphorus alloy to increase its service life.

"It's not a nickel-phosphorus alloy, it's just a single nickel-phosphorus material." Zhang Wenkai shook his head.

"Huh?" Liu Jianguo won't, what else can it be if it's not nickel-phosphorus alloy? Isn't it just an alloy?

Zhang Wenxuan, who was standing on the side, also showed a curious expression, he studied chemical engineering, and he also knew something about nickel-phosphorus alloys, and he didn't understand what the nickel-phosphorus material in Zhang Wenkai's mouth meant.

Seeing such a result, Zhang Wenkai was also slightly disappointed.

He and Cortana are working on the development of the Extreme mobile phone, which involves the design of the case, and Zhang Wenkai wants to use a solid material that is as light as possible.

However, in order to ensure its strength, the medium of the material is still limited to the body of the metal, but the mass of the metal is not light, so it is very contradictory.

However, Cortana put forward a conjecture, that is, the use of nickel-phosphorus materials.

Cortana had said that there was no such thing as nickel on her home planet, so what she proposed was just a conjecture.

That is, the use of nanotechnology to process nickel phosphorus materials, after adjusting its structure, it should be able to achieve lighter than a sponge, and even a wind can float in the air.

This conjecture was naturally taken seriously by Zhang Wenkai, so he came to the graphene laboratory from the private laboratory building and specially asked Liu Jianguo if he had any relevant knowledge.

"Can we use nanotechnology to make hollow tubes from nickel phosphorus materials?" Zhang Wenkai asked.

"Nanotechnology" Liu Jianguo groaned, he really didn't think about it.

"Let me try!" Liu Jianguo picked up the white coat and put it on his body, opened the indoor instrument, took out nickel phosphorus materials, and processed them according to Zhang Wenkai's ideas.

After all, as a materials laboratory, this commonly used material is still in reserve.

Zhang Wenxuan seemed to be curious about the baby, and he kept watching.

"How many nanometers are you going to do with the wall thickness of the hollow tube? Liu Jianguo stared at the instrument in front of him and did not look back.

"Well, let's make a 100-nanometer one first!"

"One hundred nanometers!" Liu Jianguo nodded, and then said nothing.

The buzz of the device isn't very loud, but it's audible to all.

About half an hour later, the buzz of the equipment subsided, and Liu Jianguo held a small tweezer holding a processed nickel-phosphorus material thinner than a human hair, which could barely be seen with the naked eye.

Then Liu Jianguo used other metals to make the same 100-nanometer thick hollow tube, and after measurement, it was found that nickel phosphorus was the lightest, and it was several times lighter than the second lightest.

This result made Liu Jianguo a little surprised, he didn't know that there would be such an effect, but it seems that this hollow tube is useless.

"I wonder what you do with nickel phosphorus material?" Liu Jianguo asked curiously.

"I'm going to use it as a case for my phone." Zhang Wenkai, who got this result, was a little happy, but he didn't expect Xiao Na's conjecture to be correct.

"Phone case?" Liu Jianguo shook his head, with the knowledge he wanted to master, he didn't see that nickel phosphorus materials could be used as mobile phone shells, which was a bit of a joke!

Zhang Wenkai plans to make a mobile phone shell that is both resilient and pressure-resistant, even if he says it to Liu Jianguo, he may not be able to understand it, after all, some of the technologies involved have exceeded the current level of science and technology on the earth.

"Okay, I'm fine, let's go first!" Zhang Wenkai didn't even hesitate and left directly, he wanted to tell Xiao Na about the result.

The two looked at Zhang Wenkai's back as he left in a hurry, and Liu Jianguo shook his head again, obviously still not optimistic about Zhang Wenkai's idea.

"Look, your brother is so frizzy!" Liu Jianguo felt helpless, took off his coat and left.

Zhang Wenxuan sighed, looked down at the nickel phosphorus material in front of him, which was thinner than a hair, and his eyes were full of perseverance.

He didn't expect that he was so far away from his brother, and he didn't even understand what the two said, and he couldn't help but feel so strong.

"You have to work hard, if you don't work hard, you will definitely be farther and farther away from my brother." Zhang Wenxuan muttered, did not leave the laboratory, but took out some materials and began to experiment.

Today's newly learned knowledge needs to be verified. (To be continued.) )
