Super God-Level Top Student-Chapter 1085 - 424: Choice_2

"Alright, go ahead." Matich waved his hand and set the matter aside for the time being, though he couldn’t help but think about various things.

Edward Witten, that guy, must be feeling pretty smug right now?

...

At the same time, Huaxia, Dongyue Province, Lobing City. Lobing Industrial University, Composite Room Temperature Superconductivity Laboratory.

A year ago, when the material model burst into the scene, the reports and debates about superconducting materials were all the rage on the internet for a while. But after the room temperature superconducting materials led by Dou Dou passed the laboratory tests, the news quieted down.

So there aren’t really that many people who know what advancements have been made in the domestic research on superconducting materials. Even many scholars in Huaxia are not quite clear.

This is also why Edward Witten and Peter Schultz were very skeptical about whether the collider design based on the theory constructed by Dou Dou and Qiao Ze was too idealistic. After all, according to Dou Dou’s original design, the internal structure of the collider had very high requirements for superconducting materials.

Even fewer people know that the first generation of near-room temperature superconducting materials was developed by the group that originally constituted this laboratory with the help of material models.

Later, the entire team was merged into Lobing Industrial University to form this laboratory. At that time, Qiao Ze originally planned to come and see, thinking that if there wasn’t enough research funding here, he could sponsor some in the name of Xilin Licheng.

However, because there were more important matters at the time, and after Qiao Ze mentioned this to Su Lixing, he decided to give up on Su’s advice.

Besides, Qiao Ze’s nature was of being introspective rather than extroverted, so in the end, he simply didn’t come over.

Room temperature superconductivity sounds like an awe-inspiring high-tech research, but in fact, the initial laboratory process wasn’t that complicated, even quite crude.

Start by using the arc discharge method to prepare fullerene, then mix it with other elements and compounds, and finally generate room temperature superconducting materials through a thermal reaction. Simply put, it’s this step, then that, and the superconducting material is there.

At that time, it indeed sounded simple, and almost any laboratory could do it.

But without the model, it’s actually not that simple.

First, how to prepare fullerene? Which molecules to focus on separating?

What element to choose in the doping fullerene stage? Potassium? Rubidium? Hydrogen? Or other elements? freēwēbnovel.com

Once the doping element was determined, how to choose the doping ratio? What thermal reaction to use? Hydrothermal? Or just throw it into a high-temperature furnace to burn?

After completing the material synthesis, which target material should be screened from the reactants? And what method to use for separation?

All these are problems.

The most frustrating part is, after completing this series of processes, all sorts of tests still have to be conducted. The final result is most likely a bunch of waste materials, and then you can only start over from the first step.

This is probably why the material is called a bottomless pit of a major. The whole process requires a stroke of luck in the laboratory. If luck isn’t there, the experiment might be done dozens to hundreds of times without any achievement. If luck is on your side, perhaps a small mistake can become a classic.

The advent of the material model, to put it frankly, is about integrating information and conducting billions of simulations under the model architecture to first eliminate the unreasonable ones, summarizing the most likely successful methods and steps from countless failures, and then providing rational suggestions.

When everyone starts using the material model to conduct experiments, more data can be collected for further improving the entire process, making the whole production process simpler, or further enhancing the performance.

Regarding superconducting composite materials specifically, the model directly provides a whole preparation plan. The laboratory personnel then simply have to follow the plan precisely.

For instance, to prepare fullerene, first evacuate the arc chamber to a vacuum, then input high-purity helium and maintain the flow of helium. Two high-purity graphene rods are used as electrodes in the arc chamber, adjusting the voltage through a high-voltage power supply to a certain degree, then bringing the graphite rods close to form an arc.

Maintaining arc discharge under these circumstances can vaporize the graphite rods to produce carbon plasma.

Then use chromatography separation to extract fullerene from the product, focusing on separating the C60 and C70 molecules. Then it’s doped with potassium, hydrogen, and bismuth in the specified proportions...

This is probably why some say that the material model is killing chemistry.

The output process from the material model is detailed to this point, theoretically meaning humans no longer need to study those complex visible chemical reactions; supercomputers handling it is sufficient. They can naturally simulate various reactions.

As for reactions that cannot be seen with the naked eye, those belong to the field of quantum or particle physics, and clearly have little to do with chemistry anymore.

Of course, those materials scientists initially exposed to the material model at Xilin University of Technology were right to some extent.

You can’t completely compare material scientists to parameter-tuning labor workers; after all, those specific terminologies still need to be learned to understand.

But speaking of it, conducting various material experiments now indeed doesn’t require learning for too long. Simply understanding the key points of various reactions and remembering them well is sufficient.

At the same time, this doesn’t mean material laboratories no longer need investment.

Just the opposite, investment needs to be increased to test material performance.

Just like now, Dou Dou has released the task of manufacturing a collider, and the Composite Room Temperature Superconductivity Laboratory is one of the beneficiaries. To meet the higher requirements of superconducting material preparation, the laboratory has been specially equipped with the latest SQUID magnetometry and VSM magnetometry.

Additionally, the laboratory’s data acquisition system was completely upgraded again.

There’s no other choice as the miniaturization of the collider has relatively high requirements for superconducting materials; Dou Dou has already ordered a batch of superconducting materials, and they barely meet the requirements. The critical temperature is sufficient, but the high critical density, high critical magnetic field, and material strength still need some improvement.

After all, these materials need to maintain current density at high magnetic fields to ensure that small-sized devices generate strong enough secondaries, while also maintaining a superconducting state at high magnetic fields. This series of requirements is indeed somewhat excessive.

"Director Xu, this time you folks are in luck again. This is currently the world’s most advanced SQUID interferometer, with only three in all of Huaxia, and the other two are in Xilin. The Capital’s material laboratory has been requesting for years but hasn’t received one. You guys got one first."

"Haha, Engineer Han, the way you speak. Aren’t we all benefiting from the advantages of that person in Xilin? And after all, what’s the point of such excellent equipment over in the Capital? They haven’t been assigned the task of researching superconducting composite materials, right?"

Outside the testing laboratory, Director Xu Yaoguo was having a casual chat with Han Jichun, who was responsible for this instrument installation.

Clearly, Director Xu was very happy this time, with a bright smile, unable to close his mouth.

Despite many outside claiming materials science is dead, and working in materials has no future, Xu Yaoguo believes it depends on who it is.

For instance, their laboratory is also into materials, but has been thriving recently.

Equipment they only dreamed of in the past is now fully equipped. What vibration sample magnetometer, four-point probe for resistance measurement, low-temperature thermostat, strong magnetic field source, magnetism measuring equipment...

Even the most ordinary oscilloscope is the most advanced, with ultra-high bandwidth and a super sample rate, multi-channel as standard, a high-resolution guarantee for more detailed signal specifics, ensuring the accuracy of low-amplitude signals. Coupled with various advanced triggering functions and automatic measurement analysis capabilities, it can even automatically perform waveform calculations...

You have to know, two years ago, he was still using an old oscilloscope from ten years ago, where even the most basic waveform display was often inaccurate, and it only had one channel, forcing him to borrow another one from the neighboring research group for comparisons...

Who can you protest to about this?

Now, it’s genuinely upgrading from a shotgun to a cannon.

At this moment, Xu Yaoguo was genuinely grateful for his choice back then. After getting his hands on a beta version of the material model, he stood his ground against public opinion, refraining from crazily brushing research papers under existing data like other laboratories and instead chose to wing it, resulting in a happy accident.

"Alright, I won’t keep rambling with you. Once the test is done and you sign off, I can report it."

"What’s the rush, Engineer Han? Let our researchers finish the test first. Stay here a day, and I’ll accompany you for a good drink."

"Oh no, not today. I still have to rush back to Xilin; I have tasks there. Next time, definitely!"

"What task is so urgent?"

"City-wide wireless charging system. Put simply, as long as you have a domestic phone, next time you’re on a business trip to Xilin, there’s no need to bring a charger!"
