"Alright, go ahead." Matich waved his hand and set the matter aside for the ti being, though he couldn’t help but think about various things.
Edward Witten, that guy, must be feeling pretty smug right now?

At the sa ti, 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 advancents have been made in the dostic 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 requirents 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 rged into Lobing Industrial University to form this laboratory. At that ti, Qiao Ze originally planned to co and see, thinking that if there wasn’t enough research funding here, he could sponsor so in the na of Xilin Licheng.
However, because there were more important matters at the ti, and after Qiao Ze ntioned 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 co 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 thod to prepare fullerene, then mix it with other elents 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 ti, 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 elent to choose in the doping fullerene stage? Potassium? Rubidium? Hydrogen? Or other elents?
Once the doping elent 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 thod 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 experint might be done dozens to hundreds of tis without any achievent. If luck is on your side, perhaps a small mistake can beco 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 thods and steps from countless failures, and then providing rational suggestions.
When everyone starts using the material model to conduct experints, 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 so say that the material model is killing chemistry.
The output process from the material model is detailed to this point, theoretically aning 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 so extent.
You can’t completely compare material scientists to parater-tuning labor workers; after all, those specific terminologies still need to be learned to understand.
But speaking of it, conducting various material experints now indeed doesn’t require learning for too long. Simply understanding the key points of various reactions and rembering them well is sufficient.
At the sa ti, this doesn’t an material laboratories no longer need investnt.
Just the opposite, investnt 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 et the higher requirents of superconducting material preparation, the laboratory has been specially equipped with the latest SQUID magnetotry and VSM magnetotry.
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 requirents for superconducting materials; Dou Dou has already ordered a batch of superconducting materials, and they barely et the requirents. The critical temperature is sufficient, but the high critical density, high critical magnetic field, and material strength still need so improvent.
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 requirents is indeed sowhat excessive.

"Director Xu, this ti you folks are in luck again. This is currently the world’s most advanced SQUID interferoter, 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 equipnt 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 instrunt installation.
Clearly, Director Xu was very happy this ti, 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.
Equipnt they only dread of in the past is now fully equipped. What vibration sample magnetoter, four-point probe for resistance asurent, low-temperature thermostat, strong magnetic field source, magnetism asuring equipnt...
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 asurent 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 mont, 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 ti, definitely!"
"What task is so urgent?"
"City-wide wireless charging system. Put simply, as long as you have a dostic phone, next ti you’re on a business trip to Xilin, there’s no need to bring a charger!"
