In the laboratory, Xu Chuan personally controlled the equipment to prepare improved superconducting materials.

It has been a long time since he has done experiments himself, and it is more about solving theoretical problems to drive the development of materials.

But the muscle memory is there, and the moment you enter the lab, the familiar feeling of the equipment quickly comes to mind.

Through the rubber gloves, Xu Chuan skillfully manipulated the micro robotic arm to transport the film that had completed the guided growth to the inert atmosphere protection furnace.

Here, the grown film is protected by an inert gas and heat treated at a temperature of 860°C-900°C to produce the final improved superconducting material.

After dealing with this step, Xu Chuan took off his gloves and breathed a long sigh of relief.

At this point, the entire experimental process is basically completed.

It is only necessary to wait quietly for the inert atmosphere protection furnace to complete the final heat treatment.

All that's left is to test the prepared material.

"Academician Xu, do you want to take a break, I'll come here."

In the laboratory, the assistant researcher looked at Xu Chuan, whose face was full of exhaustion, and asked.

Experiments, how to say, are partly quite easy, but most of the time, doing experiments is quite physically exhausting.

Don't look at the fact that there is basically no need to carry any large devices, heavy items or anything to do experiments in the laboratory, but precision experiments, especially material research and development, often require a high degree of concentration and attention of scientific researchers.

After all, in the whole process of the experiment, once there is an error or mistake, basically the entire experiment will be scrapped, and you can only start from scratch.

Hearing this, Xu Chuan glanced at the inert atmosphere protection furnace that had just started working and nodded.

Under normal circumstances, he wouldn't have exhausted himself.

But before today's experiment, he had already stayed up for two or three days in a row, and before he had time to adjust himself, he hurried over to do the laboratory, and his energy was naturally not so sufficient.

After handing over the rest of the work to the assistant, Xu Chuan returned to his office, leaned back on the sofa and closed his eyes for a nap.

The reason why he rushed to complete the experiment today was that tomorrow would be a report on the unified framework theory of strongly correlated electronic systems.

Considering the report meeting, and the report meeting on the construction of large strong particle collisions immediately after the report meeting, Xu Chuan was in a hurry to mention the material experiment today.

Today, the material will be made, and a superconductivity test will be done to see if the prepared improved superconducting material has the same strong magnetic field strength as in the simulation experiment.

If there is, he can hand over the rest of the test to someone else, and when he finishes the briefing, the overall test results will almost be out.

If not, using the time of his report meeting, the Chuanhai Materials Research Institute can also analyze the overall situation of the experiment and find out the problem.

Otherwise, we will wait until the report is finished, and it will take several days to delay.

Maybe for other researchers or scholars, a few days is not a matter at all, but for Xu Chuan, it is best not to waste time.

Set an alarm casually, Xu Chuan leaned on the sofa and closed his eyes for about forty minutes.

It wasn't a long time, but it was enough to relieve his fatigue greatly.

After all, young and physically able to bear it.

Reaching out to touch the phone from the coffee table, and turning off the alarm, Xu Chuan got up and stretched and returned to the laboratory.

In the laboratory, the preparation of the improved superconducting material has just been completed, and patches of silver-gray films are being transferred to glassware by the assistant researcher.

Fan Pengyue, who had already finished his work and rushed over to be a supervisor, turned his head and glanced at it after hearing the movement: "Why don't you rest for a while?" ”

Xu Chuan smiled and said, "It's enough, what's the result?" ”

The assistant researcher who followed him throughout the research and assistance quickly reported: "The morphology of the improved superconducting materials prepared by visual inspection is quite perfect, and there are no tears, wrinkles, curls, etc. Performance needs to be tested before it can be determined. ”

Xu Chuan nodded, stepped forward and put on gloves, picked up a glassware, took out the improved superconducting material film from it, and observed it carefully.

The film, which is less than the size of a child's palm, is sandwiched between the fingers, and the surface has a little bit of metallic luster.

This is a feature that is not found in high-temperature copper-carbon-silver composite superconducting materials, which are ceramic materials, although they also appear silver-gray under the gaze, but they are matte and do not appear this metallic luster.

It may be that after experimental improvement, the Cu atoms in the excess Cu nanoparticles are doped into the holes, and the magnetic traps generated change the properties of the raw materials, so that they have a reflective feeling similar to that of metalloids or a small amount of metals.

After carefully observing the appearance, Xu Chuan pinched the two sharp corners with his hands and slowly applied pressure.

The film in the fingers is not very thick, and the thickness of an adult man's nails is visually examined. Under the pressure of his fingers, this silver-gray film was slightly deformed, and the whole took on a trace of curvature.

Noticing this, Xu Chuan's pupils condensed slightly.

This is also a property that high-temperature copper-carbon-silver composite superconducting materials do not have.

After all, the properties of ceramic materials are generally almost not tough, and he is also the academician Zhang Pingxiang who added a little toughness to it through research.

And now, the raw material in the hand, which has not yet undergone whisker toughening, obviously has some primitive toughness.

After thinking about it for a while, Xu Chuan wanted to see where the limit of this improved superconducting material was, so he found a vessel and slowly continued to exert pressure in it.

As the strength increased, the arc of the deformation began to increase, but not long after, with a crisp 'pop' sound, the film in the finger burst open, turning into several fragments and splashing out and falling into the glassware.

"It is tough, but it is far less than the superconducting material after whisker (fiber) toughening, and it can achieve an arc change of about 7-8 degrees under compression, and the impact toughness should be between 8-10."

Looking at the materials that exploded in the glassware, Xu Chuan made a simple calculation.

Although the values are not high, it is still a pleasant surprise as a bonus.

After all, in terms of the physical properties of high-temperature copper-carbon-silver composite superconducting materials, the toughness value is very low, and even a small improvement is enough to optimize a lot.

If combined with whisker toughening technology, it is believed that its performance will be even higher.

In the laboratory, Xu Chuan damaged a film of improved superconducting materials when he came up, and everyone continued to be busy after just taking a look, preparing for the relevant superconductivity test.

Big boss, you can play how you like.

Testing of superconducting materials is not very difficult and can be carried out with equipment such as cryostats and Dewar liquid nitrogen containers.

In particular, there is a complete superconducting electromagnetic test system in the Chuanhai Materials Research Institute, and it is enough to put the material in it.

Xu Chuan didn't test it himself, he waited on the side.

This kind of work, for today's Chuanhai Materials Research Institute, can be said to be a small test step.

Not everyone does, but a researcher at the Superconducting Materials Research Laboratory, even a graduate student in the internship period, can do it.

Compared with the cumbersome test of the critical magnetic field, the test data of the critical temperature is the first to be made.

"The results of the first test Tc critical temperature have been released, and the current temperature is 127.3K!"

In the laboratory, the assistant researcher in charge of the test quickly reported after observing the curve falling off a cliff.

Hearing this, Xu Chuan, who had been waiting on the side for a long time, leaned over and looked at the computer screen.

The large display is divided into four parts according to the XY axis, each displaying different data.

The resistance information value, the temperature control system value, the magnetic field index value, the AC magnetic susceptibility and other data to test the main properties of superconducting materials are displayed.

In the resistance region, the previously smooth curve has now bottomed out.

In the temperature control system's numerical area, the huge number pauses at 127.3K, and the bright red color indicates the critical transition point.

127.3K、-145.85℃！

This figure happens to be in the simulation results of the simulation experiment, which can be said to perfectly confirm the theory.

"It's done!"

Looking at the data on the screen, Xu Chuan clenched his fists and almost didn't cheer!

Although the data of the magnetic field test has not yet come out, the change in the critical temperature has already told him the answer he wants.

After quickly getting out of the way and motioning for the others to continue working, Xu Chuan sat in the laboratory and continued to wait.

Nowadays, the key is no longer on the critical temperature, the final indicator still needs to look at the critical magnetic field!

After patiently waiting for more than two hours, the first round of superconductivity testing was finally completed.

The test results were printed out and sent to him as soon as possible.

Xu Chuan turned directly to the superconducting performance.

[Critical temperature (Tc):127.3K]

[Critical magnetic field (Hc): At 127.3K, the critical Hc is 40.76T, and the maximum can reach 46.68T. 】

[Critical current (Ic): 5092A/mm2 at 43T]

【Critical Current Density (Jc):】

Looking at the preliminary test results in his hand, he grinned.

This value is theoretically sufficient!

Not just miniaturized controlled nuclear fusion and aerospace engines, but also large strong particle colliders that he hadn't considered before.

With the blessing of this new material, the collision energy level may be increased by more than half an order of magnitude on the original basis!

This will bring new science to the physics community, and indeed to the whole world!

PS: The second more asks for a monthly pass!
