Chapter 397 158K
After the preliminary material model came out, Wu Tong immediately led the team to start preparing the physical material. They went through a series of predetermined preparation processes one by one. The simple wire drawing instrument that had been adjusted slowly spit out a silver-black thread that was almost invisible to the naked eye and as thin as a hair.
This thread looks thin and fragile, but it has a different kind of toughness. Under the operation of the machine, it slowly extends at a speed visible to the naked eye. In the laboratory, everyone's eyes are focused on the thin metal wire, which is a graphene wire created by combining the graphene superconducting material they have researched with special metals.
"Intercept, let's go to the testing room!" Wu Tong ordered when he saw that the length had reached the expected length. The final result still needs to be tested.
Following Wu Tong's instructions, Tao Ran operated the instrument skillfully, removed a one-foot-long wire, and put it into a sealed sample bag without contact. Then he carried the sample bag and put the laboratory equipment back together with the others to ensure that no dangerous accidents would occur after they left. This is the laboratory rule and all operations must be carried out under safety regulations.
On the testing instrument, Ruan Chengxu adjusted the operation according to Wu Tong's instructions. When the critical current density of the material reached about 158K, the rate of decrease of resistance reached a peak, and the resistance value abruptly approached zero.
The measured resistance of the material is already lower than 10^-25Ω. We can assume that its resistance is 0
"158K?" Tao Ran, Ruan Chengxu and other young team members, as well as Elder Cheng who accompanied them in the experiment, were all overwhelmed with excitement when they saw the incredible data on the display screen. They did not want to suppress their excitement at such miraculous data.
At this moment, their feelings are irreplaceable by anything!
"Mr. Wu, you have set a new record for the critical temperature of superconductors, and we have broken the world record again!" At present, most experimental data are still hovering around tens of K. It is extremely difficult to increase a value upward. But now, they have actually measured a critical temperature of 158K. What this means is self-evident!
This is the critical temperature of superconductivity at normal temperature and pressure, without any water. This is a miraculous achievement that no one in the world has achieved!
What the other side of the sea failed to do, what the Euro system failed to do...they did it with Oriental China, their General Manager Wu did it. General Manager Wu, he really implemented it deeply, he is the representative of miracles!
As expected, he is their General Wu, awesome, awesome!
"Mr. Wu, you are the greatest scientist, no doubt about it!" The R&D team exclaimed sincerely. This has always been their deepest feeling. They are deeply grateful that they can join Wu Tong's team and follow her to break world records and create one super change after another, which are almost miraculous!
Although the word "miracle" may be too common in describing Mr. Wu, every time, they still feel that only miracle can represent their most sincere admiration!
While everyone was proud and honored, they knew in their hearts that Wu Tong was the backbone of the entire team. The miracle was created by Ms. Wu, and they were just assisting Ms. Wu in turning her design into a physical entity. This was something that any experienced laboratory worker could do under the command of Ms. Wu!
Following Mr. Wu through his research and development projects, they had already put aside all their pride and were impressed by Mr. Wu, who was younger than them. No one could help but feel awe for such a Mr. Wu. No one could help but be impressed by Mr. Wu's miraculous abilities!
So what if Mr. Wu is younger? Miracles can't be accomplished just because someone is older. Those years older than Mr. Wu are just a few more years of eating white rice than Mr. Wu. There's nothing to be proud of!
At this time, Wu Tong was also very happy. Although materials have always been her area of expertise, superconducting materials have always been a deep pit field with almost no reference. From the beginning of contact with superconductors, to studying the mechanism of high-temperature superconductivity, designing superconducting material models, to creating a record for the critical temperature of superconductivity under normal pressure.
The effort Wu Tong had put in along the way was immeasurable. However, all this had resulted in a pretty good result, and Wu Tong was basically satisfied!
"Thank you for your hard work, everyone. These are just preliminary materials. There is still a lot of room for improvement in the future!" Wu Tong breathed a sigh of relief. Although they did not achieve room-temperature superconductivity, with this carbon nanographene wire, the main material of the stellarator device coil can be preliminarily determined!
The huge controlled nuclear fusion stellarator device has taken the first step towards reality from the planning blueprint. With this first step, she can really apply for project approval, not just empty talk, but also project approval based on her courage!
"Wu Tong, you are not just developing superconducting materials, right?" Seeing the final product, the experienced Cheng couldn't help but have more speculations. When Wu Tong instructed the team to continue repeating the experiment and collecting data, he followed Wu Tong's footsteps and stepped out of the laboratory at the same time and asked quietly. He always felt that Wu Tong was making a big move.
"Teacher, you have a keen eye and understand me!" Wu Tong chuckled. She was indeed not developing superconductors simply for the sake of superconductivity. "Teacher, I want to do controlled nuclear fusion!"
Wu Tong has enough authority over her teacher, and will speak frankly about future projects that will require the teacher's assistance. She doesn't mind discussing her ambitions and intentions with the teacher.
"Controlled nuclear fusion?" Even though he had already vaguely guessed that Wu Tong might have a big move, Cheng Lao still felt sorry for Wu Tong's real purpose. Controlled nuclear fusion, these five light words represent a vibration that will make anyone who hears it pay attention. It is a major area that can determine which side will be the first to enter the next track in the future.
"Yes, teacher, I want to try controlled nuclear fusion. I want to try a stellarator device that is different from the current main research field in China. The carbon nanographene superconducting wire developed this time is the material I prepared for the coil of the stellarator device!" Wu Tong nodded in confirmation. She did not take the challenge on impulse, but wanted to overcome the difficulties step by step and implement this extremely valuable major topic!
It will allow people to truly enter the era of clean energy, and also allow China to get rid of its dependence on international crude oil and truly control energy in its own hands! Through the purification and extraction of seawater, they have collected enough main materials for their initial operation, which is the prerequisite for controlled nuclear fusion.
