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 silk thread that was almost invisible to the naked eye and as thin as a hair.
This thread looks thin and seems to be fragile, but it has a special 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. This is the graphene wire they have researched by combining the graphene superconducting material and special metal to create the final product.
"Cut it off and go to the testing room!" Wu Tong ordered when he saw that the length had reached the expected length. The final result still needed to be tested.
Following Wu Tong's instructions, Tao Ran operated the instrument skillfully, removed a one-foot-long wire, and placed it into a sealed sample bag without contact. Then, carrying the sample bag, he and the others put the laboratory equipment back in place to ensure that no dangerous accidents would occur after they left. This was 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 resistance of the material was around 158K, the critical current density suddenly increased, the rate of decrease of the resistance reached a peak, and the resistance value abruptly approached zero.
The resistance of the material is less than 10^-25Ω. We can assume that its resistance is 0
"158K?" Whether it was Tao Ran, Ruan Chengxu, or other young team members, or Elder Cheng, who had accompanied them on the test, seeing this incredible data on the display screen, they couldn't help but feel incredibly excited. They didn't want to suppress their excitement at such a miraculous data.
At this moment, their feelings are irreplaceable!
"Mr. Wu, you have created 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. 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 in it. 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 President Wu did it. President Wu, he really implemented it deeply, he is a 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 was their deepest feeling ever. They were deeply grateful that they could join Wu Tong's team and follow her to break world records and create one super change after another, which were almost miraculous!
Although the word "miracle" may be too common in Mr. Wu's description, 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 General Wu, and they were just assisting General Wu in turning her design into a physical entity. This was something that any experienced laboratory worker could do under General Wu's command!
Following Mr. Wu through each project and each R&D project, they had long since swallowed up all their pride and were immediately impressed by this 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 simply by age. Those years older than Mr. Wu are just a few more years of living. There's nothing to be proud of!
Wu Tong was filled with joy. Although materials had always been her area of expertise, superconducting materials had always been a difficult field with few references. From her initial experience with superconductors, to studying the mechanisms of high-temperature superconductivity, designing superconducting material models, and finally setting a record for the critical temperature of superconductors at normal pressure, she had been working on this project.
The effort Wu Tong had put into this was immeasurable. However, all of this had resulted in a fairly impressive victory, and Wu Tong was generally satisfied!
"Everyone has worked hard. This is just preliminary material. There is still a lot of room for improvement in the future!" Wu Tong breathed a sigh of relief. Although room-temperature superconductivity has not been achieved, with this carbon nanographene wire, the main material of the stellarator device coil can be preliminarily determined!
The massive controlled nuclear fusion stellarator device had officially taken its first steady step toward reality, from the blueprints. With this first step, she could truly apply for project approval, not just empty talk or sheer courage!
"Wu Tong, you're not just developing superconducting materials, are you?" Seeing the final product, the experienced Cheng couldn't help but speculate. As Wu Tong instructed the team to repeat the experiments and collect data, he followed Wu Tong out of the lab and asked quietly. He had a feeling Wu Tong was planning something big.
"Teacher, you have a keen eye and understand me!" Wu Tong chuckled. She wasn't just developing superconductors for the sake of it. "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 vaguely suspected Wu Tong might be up to something big, Elder Cheng still felt a pang of regret about Wu Tong's true intentions. "Controlled nuclear fusion," those five light words, carried a powerful message that would shake anyone who heard it. It was a crucial area that would determine which side would be the first to enter the next phase, a crucial area for 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 challenge it on impulse, but wanted to overcome the difficulties step by step and implement this extremely valuable major topic!
This would allow people to truly enter the era of clean energy, freeing China from dependence on international crude oil and truly taking control of its energy resources. By purifying and extracting seawater, they had already collected enough of the main materials for their initial operations, which was the prerequisite for controlled nuclear fusion.
