Omnipotent Data

Chapter 436

Department of Mathematics and Physics.

One of the two is the foundation of all disciplines, and the other is the leading discipline of natural science, both of which have a detached status.

Perhaps many people think that these two disciplines have always been in a contradictory relationship where I despise you, you despise me, and neither obeys the other.

But in fact, the two disciplines have been in a friendly cooperative relationship since their establishment.

This is indeed the case when you think about it carefully. Whether it is mathematical research or physical research, it is like walking on a lonely path, isolated from the mass society, with few companions.

You can't imagine that others understand what Diophantine analysis is, and understand what condensed matter physics contains.

Therefore, for mathematicians or physicists, convenience has become one of the few colleagues who can share a common language.

Heroes cherish heroes, and that's probably what I'm talking about.

Therefore, there is no situation where the two have spoken to each other or fought for their status in the academic world.

The two professors' dissatisfaction with Cheng Nuo was not because of Cheng Nuo's status as a "mathematician", but because they questioned Cheng Nuo's academic level.

They really don't understand why Director Ordin sent Cheng Nuo, a guy who seems unreliable just by his appearance!

But Cheng Nuo was sent by the director after all, and the two professors couldn't keep Cheng Nuo aside, otherwise the relationship with the director might become very tense in the future.

So after hesitating for a while, the older researcher called Cheng Nuo. "Who, come over and help me look at some of these data."

Cheng Nuo raised his eyelids, looked in the direction of the older professor, and continued to play with his phone with his head down.

Helplessly, the older professor exchanged a glance with the young professor standing outside the vacuum chamber, picked up the pile of experimental data in his hand, got up and came to Cheng Nuo's side.

"Mr. Cheng Nuo, don't make it difficult for us. Although I don't know the purpose of the director sending you to our research group. But what I need to tell you is that this project in our hands is a first-level research project of the Royal Academy of Sciences. If the project is not delivered on time, the responsibility will not only fall on the two of us."

Cheng Nuo put the phone away, looked up into the eyes of the older professor, and said in a calm tone, "Professor Ordin asked me to come here,

I heard about the troubles you encountered and asked me to come here to help. It's not here to be angry with you. Judging a person's academic level by age alone, is it true that the professors at Cambridge University use this to identify people? That is to say, if you randomly drag a seventy or eighty-year-old beggar on the street, you will all be honored as academic masters! "

"You..." The older professor bristled with anger.

But to become a professor is not a reckless man who doesn't use his brain for anything. A few words from Cheng Nuo were not enough to make them lose their minds.

The older professor's face flushed with anger quickly returned to normal. He glanced at Cheng Nuo who was looking at him with a smile, snorted coldly, and said, "I admit that what I just said was a bit arbitrary, but what I said is all true. Common sense."

The older professor handed Cheng Nuo a stack of A4 papers that recorded the experimental data, "If you can really analyze the reason for the failure of the experiment within a day, it will prove that you are the kind of person who breaks through common sense. At that time, we will Both of you must apologize for your previous arbitrariness."

Cheng Nuo smiled. He took the stack of experimental data from the elderly professor and smiled happily.

"One day is not necessary, one hour is enough."

Cheng Nuo's confident tone made the old professor's heart pound.

In order to avoid being accused of looking for foreign aid, Cheng Nuo sat in the laboratory and looked through the pile of experimental data.

There is a lot of data, and more than 50 groups of experiments have recorded more than 100 A4 papers.

The experimental data of more than fifty groups of experiments are not the same, but the results are all the same, because they all failed.

Cheng Nuo ignored the scrutinizing eyes of the two professors from time to time, and his thoughts were completely immersed in the pile of experimental data.

…………

"Research on the preparation of nanometer ultrafine powder by electrohydrodynamic technology", this is the full name of the project.

To put it simply, it is to use the theory of electrohydrodynamics and apply it to the preparation of nanometer ultrafine powder.

Nano-powder is a solid particle material in an intermediate state between atoms, molecules and macroscopic objects. It can be used in many practical fields such as high-density magnetic recording materials, optoelectronic materials, advanced battery electrode materials, etc.

The traditional method of preparing ultra-nanodifferentials is not only costly, but also has very stringent requirements on the environment and materials, making it difficult to popularize and apply them on a large scale.

And once the research experiment of electrokinetic preparation of nano-ultrafine powder is successful, it only needs to pass through a simple quartz capillary and apply a super-strong voltage to easily prepare nano-ultrafine powder, and the cost is less than 10% of the original. Moreover, there are not so strict requirements on the materials for preparing nano-ultrafine powders.

No wonder the difficulty factor of this project is not too high, but it is listed as one of the 100 first-level projects of the Royal Academy of Sciences.

Once this thing is produced, the value it can create is simply not too great!

After figuring this out, Cheng Nuo knew why the two professors were in such a hurry.

After more than ten minutes, Cheng Nuo went through all the data and recorded all the data in his mind.

Then, Cheng Nuo closed his eyes, constructed a form in his mind, and filled in the experimental data one by one.

The purpose of the two professors is to prepare nano-superfine powder that meets the requirements, but after more than 50 experiments, the particle size of the obtained powder does not meet the requirements of nano-superfine powder.

In each experiment, only about one-tenth of the powder can guarantee a particle size below 100 nanometers. If it is only the success rate, there is no need for research at all.

What Cheng Nuo needs to do now is to find out the problem through deduction.

Under the experimental conditions for preparing ultra-nano fine powder, there are many independent variables, but there are only a few that affect the particle size of ultra-nano fine powder: the voltage of DC high voltage, the frequency of DC high voltage, the experimental temperature, the diameter of the capillary nozzle and the length of the nozzle, The pressure of conveying the melt, the resistance along the way when the melt flows in the capillary...

"Is there any draft paper?" Cheng Nuo suddenly raised his head and asked.

The older professor pointed to a corner of the laboratory, "There are all A4 papers over there, use whatever you want."

Looking at Cheng Nuo's back, the older professor rubbed his chin in deep thought.

He paid attention to the time. It was less than half an hour since Cheng Nuo got the experimental data.

Could it be...he had an idea so soon?

Regardless of what the senior professor thought, Cheng Nuo took a few sheets of A4 paper, took out the pen he carried with him from his pocket, and began to calculate the data on the paper:

[Assuming that r is the minimum average radius of the ultrafine powder, o is the surface tension of the molten metal, ￡o is the dielectric constant under vacuum, and is a coefficient related to field strength, G is the amount of liquid droplets formed per unit time, and U is the DC high voltage ...]
