Everyone will get sick. From Qiao Yu's point of view, it's okay to have minor physical problems occasionally. The most fearful thing is a sudden illness in the brain.
For example, there are always people who suddenly feel that they can do it, have some unrealistic ideas, and begin to give up their rationality and firmly want to implement them.
For example, if you feel that you don’t need to study, you can have a world in the future by playing games, relying on fists, and relying on many unorthodox things...
Or maybe you are blinded by hormones and always feel that someone of the opposite sex or the same sex will be the happiness of your life.
For most people, this disease will appear more frequently in the early stages of life, especially when they are teenagers. The solution is to beat them hard!
The classic saying summed up by the ancients that a filial son emerges from under the stick has its own truth. Using love to influence a teenage child who is in the rebellious period is generally the superpower of education experts.
Qiao Yu has never experienced stick education.
Because Qiao Xi never noticed that Qiao Yu was irrational. Even for a teenager, Qiao Yu's rationality was too terrifying.
As we all know, it is difficult for people to achieve happiness if they are too rational and completely abandon their sensibility.
This is why Qiao Xi has always been worried about Qiao Yu and doesn't even mind her children's puppy love.
After all, whose teenage children can be so rational? When doing any multiple-choice questions, they can subconsciously maximize their interests...
This seems very unlovable.
But coincidentally, for science, this kind of reason happens to be very important. After all, science does not believe in sensibility. In fact, any metaphysics in the laboratory may hide laws that humans have not yet mastered.
The reason why many laboratories exist is to search for and discover those laws that are hidden deep in the world and cannot be seen under normal circumstances.
Qiao Yu felt that he had found a method that could help many laboratories find those patterns as soon as possible.
When Chen Zhuoyang informed him that the results of the supercomputer analysis had been sent to his mailbox, Qiao Yu immediately downloaded all the results to his computer.
The results of the analysis lasted for five pages, but Qiao Yu did not read the data reports carefully. His attention was attracted by the final summary chart.
The left side is a two-dimensional heat map, which represents the modal density. The right side is a path diagram, and the blue line represents the modal path after dimensionality reduction.
If his method is correct, it means that based on the existing data, it can be roughly judged that there is a performance jump near α=30min and β=5 kJ/mol, and points to the key molecular interaction transition area.
The area with the highest modal density is around α=35min and β=25 kJ/mol. In other words, according to the current laboratory data, the fracture strength of materials produced in this area has the best recovery.
When it comes to the specific laboratory, we must first find the specific ratio of monomer to cross-linking agent when the β value is around 25kJ/mol.
The other picture is the fracture strength recovery and dynamic stress change trend chart:
Although the results are somewhat troublesome, they at least show superimposed cyclical oscillations.
After the dynamic stress reaches its peak in the initial stage, it rapidly decays and levels off. The process of strength recovery shows exponential growth characteristics, and reaches critical repair points near 20 and 40 minutes.
The next step is to send it to the laboratory for testing. If the results repeated multiple times can be stable, new parameters can be introduced.
After a brief analysis, Qiao Yu directly called Liu Hao.
"Hey, Senior Brother Liu, are you in the laboratory?"
"Yes! What? Is there any result?"
"Well, we have preliminary analysis results. We need to test them. Do you have ready-made experimental materials in your laboratory? Or do we have to wait for you to prepare the materials first?"
"Yes, yes, yes, the materials are sufficient. We are working hard on the project now. Do you want to come directly or should I pick you up?"
"I'll just go right there. I'll be there in about fifteen minutes."
"Okay, I'll wait for you downstairs."
…
In the chemistry building, Liu Hao answered the phone and hurried out of the laboratory.
Sometimes the pressure really does not come from oneself, but from the unknown.
Last week, Liu Hao met with his supervisor, Professor Zhang Zuolin, to talk about the progress of the current project.
I learned from the boss that although the Huairou Institute was slower than them in the early stage, the progress may have caught up now.
Different from the dynamic covalent bonding technology they use, the other party uses block copolymer phase separation and nanoparticle filling to achieve the same function, but most of the difficulty is concentrated in the first half.
The flexible block can provide flexibility and stretchability and improve the mechanical properties of the material; the rigid block provides mechanical strength and durability to ensure that the material is not easily damaged.
Photothermal nanoparticles are added to the material to control the temperature response of the material. At the same time, these nanoparticles can also be used to regulate the thermal conductivity of the material so that the material maintains stability in high or low temperature environments.
This resulted in the other party's technical difficulties being very high in the early stage, mainly focusing on the synthesis technology and structural characterization stages.
The main difficulties of our own technology are concentrated in the chemical design and optimization stages, but the synthesis and characterization process are already very mature, and preliminary experiments can be quickly advanced.
It's like they had everything going well before, but are currently stuck in the optimization stage.
But if the other party once overcomes the synthesis of block copolymers and the quantification of the contribution of nanoparticle filling to performance, the later stages will be relatively simple.
So after learning that Huairou Institute had overcome several technical difficulties, the boss said that we should just do our best and let fate dictate.
If you really can't compete with each other, the project and data will be sealed first. Anyway, two different technical solutions have other advantages and disadvantages.
Even if we cannot compete with each other this time, these studies are still valuable, and there may be opportunities to restart in the future, so it cannot be regarded as a waste of resources.
To be honest, this project has not had a big impact on the mentors. The big guys are well-informed, and there are many cases where people choose important projects with different ideas and fail to compete with others.
The initial investment is all given by Party A, so it is common for the company to be unable to compete with the other party. It is just a matter of taking on other projects.
But for the members of the research team, it means that their efforts for such a long time have been in vain, and they are still somewhat unconvinced.
Although the boss is quite nice, there is definitely no reward if the research team fails to produce results. You can imagine how much of a blow to everyone's morale.
So although the instructor didn't put any pressure on him, Liu Hao felt even more pressure.
But unfortunately, the situation in these laboratories cannot be done well under pressure. Without a clear direction, you can only run around like a headless fly.
In the first few days, he would often ask Qiao Yu and Chen Zhuoyang on WeChat, but during this period, he asked less frequently.
After all, mathematicians are not omnipotent.
Maybe Qiao Yu performed amazingly last time, but that was because of the directional data support.
When reviewing the test afterwards, almost all the members of the research team exclaimed, "It's so simple, why didn't I think of it at the time?" This is proof.
The situation this time is obviously different.
Therefore, after there was no news from Qiao Yu and Chen Zhuoyang, Liu Hao did not continue to inquire, but placed his hope on the so-called "metaphysics".
Well, this is obviously not a good habit for scientific people. But many results are really a wonderful intertwining of science and luck.
There are never any shortage of such examples in the laboratory.
And to be honest, many times, pinning your hopes on "metaphysics" is even more useful than pinning your hopes on data analysis.
Really, as an experimental dog, before getting the results, you can never guess what wonderful results the data analysis software R, python and the like can produce.
The results produced by data are often so bad that people can't bear to look at them. Therefore, Liu Hao once thought that Qiao Yu's method would probably not be easy to use.
After all, the codes they use to run data have all produced results before. As for Qiao Yu's new method, although they don't know about it, since it is new, it must not have been tested in practice.
But who would have thought that just when he had given up on getting effective help from Qiao Yu, Qiao Yu called again, and from what Qiao Yu said, it seemed that he had found a solution?
No matter what, Liu Hao still had a glimmer of hope in his heart, and hurried downstairs and started pacing at the door of the Chemistry Building.
Fortunately, Qiao Yu was really punctual. He said it would take fifteen minutes, and almost missed the time by riding a small yellow car to the chemistry building.
Liu Hao rushed forward immediately, stretched out his hand to help Qiao Yu hold the front of the car, and then asked: "Um...is there really any result?"
"Well, we can't guarantee the accuracy for the time being. Please take a look at these two pictures first." Qiao Yu took out two printed charts from his bag and handed them to Liu Hao.
The color printing machine that Chen Zhuoyang prepared for Qiao Yu was indeed very useful.
Liu Hao scanned it briefly and was a little confused.
"What analysis software is this? And what does this highlight mean?"
"Hey, this needs to be kept secret. As I said before, I used a very interesting new method. As for the first two-dimensional map, the brighter the color, the denser the effective points are in that area."
"Forehead……"
"It's okay, Senior Brother Liu, you don't need to fully understand the meaning of these pictures. If you can trust me, you will do what I say in the laboratory today, and then we will talk after reading the results."
"Then I must trust you. Don't worry, I just asked everyone to stop and I'm just waiting for you to come."
In one sentence, the trust level was filled up. But in fact, there was nothing they could do. The current situation was obvious, and their luck was not that good.
There has been no breakthrough progress in recent times. At least they have not been able to find a stable optimization direction.
Of course, if the mentality was not so impatient, the current situation would actually be good.
For more than half a month, they tried many wrong methods. If they slowly used the elimination method in this way, they would definitely find a correct way.
It’s just that we don’t know how long it will take. Research on new materials is often like this, with constant trial and error, and then waiting for a miracle to appear, and then thinking of ways to make this miracle reproducible stably.
Especially when developing functional materials in complex systems, this trial-and-error experimental nature is even more significant.
Of course, even if a miracle occurs, it is very difficult to reproduce the miracle stably. As long as the non-linear relationship between variables is not fully understood, occasionally beautiful data can even make the experimental dogs more miserable.
But for Qiao Yu, these are not problems. Now it is not just a problem of this topic.
If this method really works, then what Qiao Yu wants to think about next is how to make money... Ah, no, it should be about how to benefit the major research groups in China!
Therefore, Qiao Yu is now not only the mathematical consultant of this research group, but in a sense, Liu Hao's research group is also his experimental group. In this sense, the two parties are already in a cooperative relationship.
"Okay, let's go to the laboratory first." Qiao Yu smiled, and his confident look made Liu Hao feel much more comfortable.
Soon after arriving at the laboratory, Liu Hao did not lie to him. Sure enough, everyone in the research team stopped what they were doing and were waiting in the conference room for him to issue instructions.
Qiao Yu didn't even greet anyone. After saying hello, he entered the commander's state.
"Well, looking at the data you provided before, I should have already mastered the relationship between the molecular binding energy and the ratio of monomers to cross-linking agents, right?"
"Well, we are still confident about this. It's not a big problem."
"Okay, now I need to make the molecular interaction intensity between 20-30 kJ/mol, and prepare five copies of each 2kJ/mol corresponding monomer and cross-linking agent ratio. Isn't that a big problem?"
"Ah? Such a small gap..." Zhang Haoyuan was just about to raise a question when Liu Hao glared at him.
"Stop talking nonsense, just do whatever I ask you to do! Qin Zhongliang, help Xiao Zhang prepare the solvent. Remember to be careful. Five parts of each are marked."
"By the way, I don't know the minimum amount of solvent required for each test. You know this, but each part should be two-thirds more than the minimum amount. A total of thirty parts are needed. Make sure there is no mistake."
Qiao Yu emphasized again.
"Don't worry, this is a basic operation, they won't make a mistake. It's just that the interval is too small, and the ratio of monomers and cross-linking agents may be controlled to two decimal places, which is more troublesome."
"Well, slow down a little, there's no rush anyway."
"By the way, with so much preparation, are you going to do five experiments today?"
"No, this is the first time. I told you before, I need some data. The next step is..."
…
Well, with Liu Hao's support, the subsequent laboratory operations actually went very smoothly. Everyone suppressed any questions they had.
For Qiao Yu, he is actually not familiar with the entire operation process. He is only responsible for the data results.
As for those people in the laboratory, they are responsible for implementing Qiao Yu's opinions in a way they are familiar with.
Fortunately, Qiao Yu didn't make any excessive demands. At most, he would just make a lot of samples at one time, which seemed wasteful.
And this time is different from last time.
The preparations are sufficient, and the required solvents can be prepared immediately. After preparation, it is left to stand in the solution and wait for the cross-linking reaction to proceed.
The key to affecting material performance is the process of temperature-responsive monomers and cross-linking agents forming gels through free radical polymerization.
The proportion of different materials, temperature, synthesis time, and other factors may affect the performance of the final material.
After two hours of busy work, thirty samples were already placed on the experimental table of the constant temperature reaction box.
Each sample was marked with a number at Qiao Yu's request, and was quietly arranged under different constant temperature conditions, waiting for the completion of the free radical polymerization reaction.
The atmosphere in the laboratory seemed extremely quiet, except for the faint hum of the temperature-controlled instruments in the reaction box.
Liu Hao finally had time to discuss with Qiao Yu those charts that seemed to be very regular.
“These are all analyzed using our data?”
"Yes, if it succeeds, I have to thank Senior Brother Chen. He has worked hard during this time. Your data is very messy and it will be very troublesome to sort it out clearly."
Qiao Yu nodded and replied.
He didn't plan to reveal how he did it specifically for the time being, but it was still necessary to help Chen Zhuoyang show his merit.
After all, Brother Chen is very useful. There are just a few people.
Qiao Yu even felt that Senior Brother Chen should quickly recruit a few students and cultivate them into his temperament.
"Of course, how was this result analyzed? Didn't Professor Lu say that our data has no statistical significance?"
Although Qiao Yu said to keep it secret, isn't it just idleness? Liu Hao was still very curious about these pictures.
Even if he doesn't understand how the analysis results of these pictures come from, or even doesn't quite understand how to interpret them correctly, at least he can see that there are certain patterns in these pictures.
This also made him suddenly feel confident. After all, the requirements given by Qiao Yu were very targeted.
"It depends on the situation. To put it simply, I have made some transformations of some commonly used mathematical methods. You can understand it as first eliminating the impurities in complex data through some high-dimensional means.
But let me tell you first, don’t have too high hopes. I’ve told you before, this is just a test of a new method, and I don’t necessarily guarantee that it will work.”
Qiao Yu seriously gave Liu Hao another vaccination.
The voices of the two were not quiet, and naturally they fell into the ears of other people in the laboratory. But no one said anything...
Everything has been done according to Qiao Yu's request. To complain at this time is just a flaw in the mind.
"Haha, Qiao Yu, you don't have to keep stressing this. In fact, if you stay in the chemistry laboratory for a long time, you will know that failure in the project is the norm in many cases, and success is occasional.
The situation last time was different from this time. First, the topics were relatively important, and there was competition this time. Second, there were successful cases before. So we had high hopes. Alas...
In fact, if you really want to talk about it, when we conduct experiments and there are no results, we have been numb for a long time. It’s just that some less important topics are simply abandoned without results.”
Liu Hao said in a carefree manner.
In fact, it is really easy to become numb in the research group. It is just being eliminated all the time. I cannot accept that a lot of work is useless, and I have been eliminated at the master's level.
At the doctoral stage, everyone's mentality can be said to be better, but there is still a sense of frustration that there are no results in the laboratory.
It's just that once you get busy, you don't have time to feel this kind of frustration. After all, even if Party A invested in the early stage, they are the ones who stay in the laboratory every day.
But what can be done? Party A has chosen two different directions from the beginning. In fact, it is destined to a certain extent that one side's methods and ideas will be eliminated.
Of course, there is a possibility for both parties to achieve results, but it is unlikely that such a thing will happen to everyone's satisfaction.
After all, funds are limited. From a cost perspective, if you have a mature solution, there is no need to continue investing in another immature solution.
Unless it can be proven that another solution is more useful or has shown extremely high value in another field, it will be possible to continue to take it out of the sealed files and continue research.
After listening to Liu Hao's words, Qiao Yu just smiled. He didn't quite believe that Liu Hao was really so free and easy.
Otherwise, I wouldn't have run downstairs to pick him up as soon as he called me and said he was coming. However, it is basic courtesy to see through the situation without telling him.
While there was still some time, Qiao Yu began to think about how to find the next partner, so he took the initiative to ask: "By the way, last time I heard you said that another chemical laboratory also took over Party A's task. The method used was not very good.
Same thing, do you know how far they have gone?"
Liu Hao shook his head and said with a wry smile: "The other side is a competitor, how could we know so clearly. But last week I heard from the boss that the other side has solved two key problems.
One is a breakthrough in polymerization technology. It is said that their different blocks have obtained good phase separation structures. The other is the optimization of nanoparticle interfaces.
Of course, it does not mean that they are ahead. Their technology needs to deal with the synergy problem of two complex material systems and involves the optimization of multiple chemical and physical processes, which is actually very troublesome.
So the boss also said that the other side may be setting off smoke bombs just to make us give up early. So it’s really hard to say what their situation is. Not to mention that our industry sometimes depends on luck.”
To be honest, he didn't really understand the chemical jargon that Senior Brother Liu said.
But he has already obtained the key information. Because as long as it involves the optimization of multiple chemical and physical processes, it will definitely require massive data analysis.
Chemical processes are complex, as are physical phenomena such as phase separation, heat conduction, and stress distribution. Such complex processes will certainly be accompanied by nonlinear and dynamic changes.
The parameters involved are similar, such as ratio, temperature, reaction time, solvent concentration, polymerization rate... the more complex it is, the more variables there are. This also means that if he can succeed with Senior Brother Liu, the other side should also be able to succeed.
Even if the two sides use different technologies.
So Qiao Yu asked directly: "Oh, then if their technology also requires the optimization of various chemical and physical processes, and it must be inseparable from mathematical analysis, they should also find foreign aid, right?"
Senior Brother Liu nodded and said: "I will definitely ask for help when it comes to this matter. But Huairou Institute is a research unit directly under the Chinese Academy of Sciences, you know. They have no shortage of partners."
"Yes, that is, many math people will cooperate with them on projects, Qingji, Qingke, and many other similar ones. In short, they usually have no shortage of projects. And their equipment is also very good!"
Zhang Haoyuan next to him couldn't help but add something.
Qiao Yu nodded, probably understanding the situation at Huairou Institute. But this made him want to contact the other party even more.
If he could know the progress of the other party, he could probably judge the attractiveness of his analysis technology to the laboratory.
As long as his method is effective and efficient enough, at least higher than the opponent's foreign aid, there will definitely be many research groups wanting his help to contribute to some results.
As for trying to get in touch with the other party, it shouldn't be a big problem. Both my tutor and my master's grandfather are leaders in the Chinese mathematics community, so it should be easy to inquire about this kind of thing.
If his method can be successful in Senior Brother Liu's research group, it shouldn't be a big problem to go back and ask Director Tian to prepare a lecture for him, and then invite the person in charge of the opposite project to participate.
Obviously Liu Hao misunderstood Qiao Yu's meaning and said with emotion: "Really, Qiao Yu, you don't need to be nervous about our project. We won't blame you if we can't handle it.
In our line of work, 70% of it depends on hard work, and the remaining 93% is destiny. If you can succeed in anything, then I have to think about what to say at the dinner for Sweden to win the Nobel Prize."
These words actually made the atmosphere in the laboratory more relaxed, and everyone started joking. They were probably words to remind their senior brother not to forget each other in the future.
Liu Hao also smiled and joked a few words with the team members. Qiao Yu was also listening to everyone's banter, which felt pretty good.
At least everyone can still have fun in the midst of hardship, which shows that the mentality of the team members is very stable. Qiao Yu likes partners who can maintain a stable mentality in the face of adversity.
After laughing for a while, Liu Hao suddenly started playing music again...
"It's almost done. Stop joking around. The time is coming. Let's go and look at the samples we are responsible for. When the time is up, hurry up and get tested. Qiao Yu is still waiting for the results.
The reaction time required for each group of samples is different, so don’t confuse the important things by just taking advantage of Lehe, and be careful to eat the first one!”
It can be seen that Liu Hao is still very authoritative. With one or two words, he took the initiative to return to the laboratory next door from the office.
But then again, the polymerization time of the first batch of samples has indeed almost arrived.
While everyone else was busy serving samples, Liu Hao stayed by Qiao Yu's side, chatting with each other.
Let’s not talk about experiments, just talk about the messy things in life. I’m embarrassed to let Qiao Yu wait here...
"By the way, did you hear that? Yesterday, there was a guy from the technical school next door who allegedly went to the college to stand up for his girlfriend and had a fight with the counselor there."
"Ah? Is there such a thing? Which major in the technical school?" Qiao Yu just got interested and planned to listen to the gossip, when suddenly there was an exclamation from the laboratory...
Before Liu Hao could stand up, Chen Jiang had already rushed into the office. His eyes stayed on Qiao Yu for several seconds and said, "Qiao Shen, are you too awesome?"
After finishing speaking, he looked at Liu Hao and said: "The basic parameters of the first batch of samples have all reached the benchmark values ​​we measured before. The tensile strength of Nos. 1-3 and 1-4 has been significantly improved compared to the previous test.
.
In addition, the response temperature, phase change temperature and response speed of Nos. 1-3 and 1-5 are better than those tested before. Now we have to wait for the self-repair efficiency, memory retention ability and fracture strength recovery rate to wait for some time.
Get results.
But judging from the current situation, the average basic data of the first batch of six samples are much better than what we did before! Visual inspection of the main performance data will definitely not be bad!"
After listening to Chen Jiang's report, Liu Hao glanced at Qiao Yu subconsciously... Is this thing really useful?
After all, six samples in a batch can all have this kind of performance, so it is obviously impossible to fool them.
Qiao Yu also smiled happily. He didn't need to look at the data. As long as he saw Chen Jiang's excitement at this time, he knew that the data analyzed this time must be useful.
It shows that his method is correct. As expected, mathematics can dominate many things.
"Don't worry, there are still five batches of samples, we will test them all. According to the chart we calculated, theoretically it should be the third or fourth batch...
Well, specifically, the current optimal values ​​will appear in samples No. 3-3, 3-4 and 3-5, as well as the fourth batch of samples. Of course, it may not necessarily meet the parameter standards you require, but
The data among these batches are definitely the best."
Qiao Yu explained.
Liu Hao opened his mouth, as if he wanted to say something, but couldn't say anything for a long time...
Qiao Yu felt embarrassed and added: "Well, senior brother Liu, don't look at me like that, it's just basic skills. You will know after you learn mathematics.
After you learn a lot of mathematics, analysis becomes instinctive. Well, why don't you go to the laboratory and take a look first? I'll be fine here by myself, and I can still read the literature."
Liu Hao nodded quickly and said: "Okay, um, Qiao Yu, you rest here for a while, and I'll go over to check the situation first, uh... I'll treat you to dinner tonight, let's go out to eat! Remember, Qian
Chapter completed!
