The key to predicting which elements can work with hydrogen to construct the ideal lattice based on the electron arrangement in the actinides to produce strong electron-phonon interactions, and then to generalize this fixation procedure to the entire periodic table is to summarize a large number of experimental data.

After all, Liu Feng did not lack the corresponding experimental data in his mind, and if any experimental data could not support such an induction, he could simulate a lot in a short time.

It's just that although his brain can store a large amount of experimental data, the processing of these data and completely memorizing them are two different concepts, and many times, Liu Feng must use computers and corresponding processing tools to find the inevitable connection between these data very intuitively.

That's why he often stays alone in his bedroom or office.

Only when he has a certain grasp or idea of the final result, will he really verify it with the help of real experiments.

Therefore, many times, in the eyes of outsiders, the experiments designed by Liu Feng are very targeted, with almost no superfluous procedural steps, as if they were born to exist for this answer, and it is for this reason.

Use the answer to reverse the process, as long as you are not too low, you can do it with a little effort, let alone a college bully like him who can be hanged!

This time, Liu Feng is certainly no exception.

However, unlike the collision experiments of the super collider, the relationship between the various elements of the periodic table and the superconducting properties is more complicated.

However, there are more than 100 kinds of metallic and non-metallic elements, coupled with the different electron arrangements and distributions of these elements, and the resulting superconducting characteristics are also very different, even Liu Feng, who has a super brain, has a headache in front of these data.

Fortunately, there are also classifications between elements, such as actinides, lanthanides, etc., although the elements are different, but the predecessors have long summarized the similarity of these elements, which gives Liu Feng, who is standing on the shoulders of giants, I don't know how much energy has been saved.

Unlike actinides that have been shown to have superconducting properties, it is unknown whether other elements have superconducting properties.

Therefore, after consulting the literature, Liu Feng of the former can quickly simulate it, and a piece of paper and pen can carry out research, while the latter must sum up experience in countless failed experiments.

Liu Feng stayed in the bedroom for almost three days and three nights, trying the elements of the periodic table, and he only found 58 elements with superconducting properties; however, the superconducting properties of these elements seemed to have no relationship, and after a few days of racking his brains, he almost thought that his method was wrong!

simply on the lanthanide element, and finally gave him a small surprise, which made him firm in his thoughts.

Therefore, Liu Feng temporarily put aside the study of the superconductivity characteristics of other elements and decided to summarize the superconductivity program of lanthanides first.

Similar to actinides, lanthanides can also cooperate with other elements to form an ideal lattice, resulting in strong electron-phonon interactions, and because the atomic number is generally higher than that of actinides, it has advantages in terms of radioactivity and safety.

This time, Liu Feng had to do experiments that included the construction of ideal lattices for lanthanum and lutetium, two of the most representative lanthanide oxides.

Luckily, the materials he used in his experimental recipes can be found in the lab, and those he can't find can be borrowed in the lab next door.

It's just that, unlike the simulation experiment in his mind with the help of his ability, the experiment in reality seems to have more unknown influencing factors.

Although Liu Feng thought he had thought it through, it still took him three full days and countless failures to successfully prepare the two elements into a qualified oxide with a project lattice—under the illumination of the light, it is like a flying saucer shell that exudes a sci-fi atmosphere in a science fiction movie.

These two things look similar, like two solar panels, but both are full of metallic textures.

On the surface, it doesn't seem to be anything special, but when you look at its microstructure under a scanning electron tunneling microscope, it is very different from the ordinary hydride lattice.

Without staying in this short-term joy of victory, Liu Feng struck while the iron was hot, put two lanthanide metal oxides in the experimental instruments prepared in advance, and began the second crucial step of verifying the properties of superconducting materials——

Environmental Simulation!

The most common environments that affect the superconducting properties of superconducting materials are temperature, pressure, and energy scattering, so the so-called environmental simulation is mainly to coordinate the intensity of these factors to find an environmental system that is most suitable for the formation of superconducting properties.

This operation requires a lot of technical requirements for the experimenter, and it is not as simple as the mobile phone film.

The fluctuation of temperature is too fast, and the pressure is uneven or even unstable, which is likely to make it difficult for superconducting materials to show their superconducting properties, and under the condition of strong current, the materials can be burned out in an instant without waiting for a few seconds, changing the perfect lattice characteristics of metal oxides.

Although he had tried to operate with other materials before, Liu Feng still failed many times.

It took a whole morning to successfully test the optimal superconducting environment for a piece of lutetium oxide.

Obviously, the end result is quite gratifying, minus 45 °C, 9800 atmospheres - compared to the actinide generally up to 1 million atmospheres, the conditions are obviously 'favorable', at least, it has a certain practical application value!

Looking at the fingernail-sized lutetium oxide material reflecting the charming brilliance under the light, and then looking at the several sets of data displayed on the instrument, Liu Feng couldn't help but sigh in his heart: If you know what this thing is, what is it for, and how to use it, I am afraid that no one will be too expensive if I offer a price of hundreds of millions of dollars, right?

After a short while, Liu Feng packed up the samples, including the remaining materials in the glass bottles of medicines, and packed them one by one.

It has been preliminarily confirmed that the oxides of lanthanides have superconducting properties, and their conditions are not very harsh, although they still do not reach the state of superconductivity at room temperature that he is satisfied with.

Now there's one last step left.

That is to summarize the procedure of how to construct a perfect lattice between lanthanides and oxygen!

With the help of Academician Cui, Liu Feng, who has already summarized the actinide program, is basically familiar with the operation by himself this time, although he is not very proficient.

Continuing to simulate the environment of lanthanum oxide materials, Liu Feng's movements became more and more chic and skillful, and the tweezers in his hand waved his fingers like an arm, fixing a piece of material the size of a fingernail in the test instrument, and then carefully closed the lid, adjusted the experimental parameters, and continued to power on.

Fortunately, it also belongs to the lanthanide series, and with the successful experience of lutetium oxide, and he has summarized a general range of the program before, there are only slight changes in the environment in which lanthanum oxide is used.

After several failures again, after completing the final environmental micro-operation, Liu Feng still didn't dare to be careless, and finished powering up with his heart, until the final result was displayed on the computer screen, he let out a sigh of relief, and gently wiped the sweat on his forehead with his sleeve.

"Perfect!"

Looking at the data on the instrument, Liu Feng's heart was full of excitement, as well as a trace of piety that even he hadn't expected.

Yes, it's piety.

As a researcher, he is a devotion to science.

The article is made by nature, and the magic hand is even good.

Like the artworks of those artists, Liu Feng feels that this process is likely to be shown to all mankind by God's hand, and the economic value behind it is much dimmer compared to the academic significance of its existence.

Taking a deep breath and restraining the excitement in his heart, Liu Feng substituted the data into the scope of the program summarized before, continued to refine, and finally came up with the final 'perfect' program.

Everything seems to have been completed, and all that remains is to verify the correctness of the procedure.

I hope that the final test result will not disappoint him!

Therefore, Liu Feng continued to complete the lattice structure of other lanthanides and oxygen elements, put these oxides into a pre-calculated environment one after another, set to take a photo every 10 seconds, and record the experimental data every second.

……

The sky outside the window was already dark.

At some point, Liu Feng, who fell asleep on the table, rubbed his eyes, moved his stiff arms, and stood up from the chair.

Then, the first thing he did when he stood up was to walk to the experimental instrument and check the status of the sample and the experimental data that the instrument had finally frozen.

It was not burned, and the experimental data did not show a few capital letters 'ERROR'!

Seeing these two points, Liu Feng was overjoyed, and then looked at the computer next to him, and quickly skimmed through the photos taken and the experimental data recorded once a second like flipping through a slide, and memorized them in his mind.

"It's done!"

After deducing it in his mind and comparing it with the pre-designed data, Liu Feng's fists clenched and he almost couldn't hold back his shouting.

From yesterday afternoon to now, he has done a total of 26 sets of experimental simulations for the verification of the remaining 13 lanthanide oxides, and none of them have burned out of the sample!

The result was so perfect that Liu Feng himself was very surprised.

He originally thought that even if the approximate superconducting environment of the material could be calculated in advance through a fixed program, a certain deviation was absolutely indispensable, so some materials were likely to generate partial resistance under long-term power-on, and eventually they would be damaged in a strong current environment.

Unexpectedly, his calculation program was so perfect, and the calculated environmental data made the superconductivity of these materials amazingly good.

There is no doubt that a procedural summary of the superconducting properties of lanthanides, he succeeded!

If the success of actinides can be explained by luck, is the success of lanthanides also a kind of luck?

No, absolutely not!

Liu Feng is very sure of this.

This proves that his ideas, the direction he is working towards, are completely correct!

As for the other elements, although he has not yet been able to summarize this similar procedure, it also makes Liu Feng maintain his previous speculation, and the reason why he has not succeeded is only because his experimental data is not sufficient, or he has not discovered it for a while, which does not mean that he is on the wrong path!

Lanthanides and oxygen form a perfect lattice that allows the material to form perfect superconductivity at temperatures ranging from -50 to -30 degrees Celsius, and at atmospheric pressures ranging from 8,000 to 12,000 °C!

Perhaps, for room temperature superconducting materials, there is still a certain gap, but for the most common low-temperature superconducting materials on the earth today, this is already a new height!

On the premise of ensuring safety, minimizing the impact of the environment on superconducting materials is the biggest pursuit of the industry!

It's like the superconducting electromagnet used in someone else's super collider only needs room temperature conditions, while yours needs a low temperature environment of more than minus 200 degrees, so it must be equipped with a complex cryogenic cooling system, and the market competitiveness is high.

Of course, this comparison may be a bit one-sided, after all, the requirements of room temperature superconducting materials in other aspects may be much stricter than those of ultra-low temperature, and this new room temperature superconducting material, even if Liu Feng makes every effort to tackle key problems, I am afraid that within one or two years, satisfactory results will not be achieved.

But there is no doubt that this route is completely feasible, and the superconducting properties of lanthanides, and the fixed procedures for the environment required to calculate such superconducting properties, will provide endless imagination for the entire industry!

Therefore, Liu Feng knows very well what the results he has made these days of forgetting to sleep and eat mean something.

The door to success has been knocked open by him, and the final result seems to be close at hand!

Encouraged by the success of lanthanides, Liu Feng is full of confidence in the direction he is working towards!

The next thing he had to do was just the water grinding kung fu of grinding the iron pestle into an embroidery needle......

Taking a deep breath, he closed his eyes and continued his experiments simulating the superconductivity properties of other elements.

……

As Liu Feng predicted, in addition to the 15 actinides and 15 lanthanides, there is also a certain inevitable relationship between the other 28 elements with superconducting properties.

Reading the book a hundred times and seeing its meaning is self-evident, and it seems to have a certain truth in the experiment.

As time passed, Liu Feng simulated more and more experiments, and these connections slowly appeared in his mind, and finally through the verification of real experiments, he finally summed up four fixed calculation programs including lanthanides and actinides.

He, again, did it!

Looking at the calculation programs he summarized on the computer, Liu Feng's heart felt a sense of accomplishment and happiness.

Moreover, what made him even more full of accomplishment was that with his exploration of the confidential literature of the Materials Research Institute and the study of these elements of the periodic table, he also found that there may be some special connection between these elements in other aspects, such as compressive properties and optical properties......

Driven by interest, Liu Feng casually summed up these special connections and formed several fixed calculation procedures, and put them aside without paying too much attention to them.

Eventually, the experiment was over.

Unplugged the power supply, Liu Feng kept the samples of superconducting materials he made in pre-prepared bottles.

Immediately afterwards, he saved all the experimental data and photos on the computer to the USB flash drive, and destroyed all the original data on the computer and the equipment, leaving no one.

After cleaning the laboratory and making sure that no "interesting" things had been left behind, Liu Feng left the laboratory happily and prepared to return the key to the security personnel responsible for managing the laboratory equipment.

Coincidentally, when he went out, Liu Feng ran into Professor Jiang again.

Seeing Liu Feng, Professor Jiang Yang greeted him with a smile and said, "The experiment is done?"

Liu Feng nodded, smiling: "Well, it's done." ”

Originally, it was just a face-to-face, but Liu Feng suddenly thought of something and stopped Professor Jiang, who was about to walk into the office.

"By the way, Professor Jiang, how is your recent research progressing, and is it still going well?"

A few days ago, Liu Feng saw that Professor Jiang had a sad face, and seemed to have encountered something difficult, so he asked casually, but he didn't expect that he thought it was very secretive, after all, this professor was in the military industrial system, however, Professor Jiang actually took the initiative to come to him one by one, and seemed to believe that Liu Feng was 'his own person' and would not leak secrets.

It's just that the only thing that didn't tell him was what exactly this material would be used for.

In this regard, although Liu Feng also has some guesses, he is still not sure after all.

Professor Jiang Yang's recent research seems to be a certain kind of optical material, and he is also interested in it, but the result is that he finds that he can't help Professor Jiang at all with these problems!

Therefore, Liu Feng, who was unwilling, kept checking the literature on this subject in the database of the institute during the waiting time of the experiment to enrich his knowledge base, otherwise, in the end, he would not have accidentally summarized the calculation procedures of these things that had nothing to do with him.

Speaking of his research, Professor Jiang's brows furrowed into the word 'Chuan', shook his head, and sighed: "Alas, it's still the same! You also know the difficulty of this aspect, and in a short period of time, you can't figure it out at all, let alone make any breakthroughs." ”

Really!

Liu Feng seems to have expected it.

In just over a month, if you want to make a breakthrough in this area, unless - it is almost impossible to open like him!

merely

Not everyone is called Liu Feng!
