Chapter 530: Separation Successfully!
Liquid helium can reach lower temperatures than liquid nitrogen.
Since the superconducting critical temperature of the material is still unknown, using liquid helium as a coolant is definitely a safer approach.
Xu You seemed to be very sure of the superconducting critical temperature of the material, and directly gave up on using liquid helium as a coolant.
"No need. The new type of iron does not require such a low temperature to achieve superconductivity. There is no need to waste more expensive coolant unless it is necessary." Xu You said with a smile.
"Yes, teacher."
Although normally speaking, when the properties of a substance are unclear, one should be fully prepared.
However, since Xu You has already said so, Lin Shi will not have any doubts.
Lin Shi didn't know why Xu You was so confident in his judgment.
But over the years, there are so many things that Lin Shi cannot understand about Xu You. Lin Shi feels that this may be the gap between ordinary people and geniuses.
The other material experts present were observing the experiment with curiosity.
They all knew that Xu You's achievements in the field of superconductivity were second to none in the world, and it was precisely by virtue of his research in this field that Xu You won China's first Nobel Prize in Physics.
However, they did not quite believe that Xu You could accurately determine the superconducting critical temperature of the new type of iron before successfully purifying it.
After a brief exchange, Xu You and Lin Shi continued to conduct their experiments as if no one was around.
The cooling task seems simple, but to lower the temperature quickly and accurately is like a chef's control over the heat, which cannot be mastered overnight.
Xu You had started practicing these operations long before he became a formal student of Jijing University.
It is precisely because of his millions of experiences that Xu You can control the drop in temperature so skillfully and accurately.
Although Lin Shi is somewhat inferior to Xu You in ability, he is just as hardworking as Xu You.
"Lin Shi, we are almost reaching the superconducting critical temperature. We need to slow down."
"Yes, teacher."
Xu You realized that the temperature at this time was already very close to the superconducting critical temperature of the new type of iron, so he hurriedly slowed down the cooling rate.
Even though Xu You is very confident in his simulation, there may still be some errors.
Just at this moment.
Xu You and Lin Shi saw at the same time that the current data on the testing instrument had undergone a huge change.
Such a huge change can indicate that the resistance of the metal material has reached a very small value.
Because the measured material contains other impurities besides the new type of iron, the entire material is not considered a strict superconducting material.
But such changes are enough to prove that Xu You's prediction was completely correct.
"Teacher, your prediction is correct!"
Seeing this experimental phenomenon, Lin Shi couldn't help but blurt out excitedly.
At this time, Lin Shi still couldn't figure out how Xu You successfully predicted the superconducting critical temperature of the new type of iron.
Lin Shi has nothing but infinite admiration for Xu You.
On the other hand, Xu You did not show any emotional fluctuations due to his accurate prediction, and continued to speak calmly:
"Lin Shi, prepare to apply an external magnetic field to separate the matter."
"Yes, teacher."
Next, Xu You and Lin Shi each performed their duties and conducted the experiment carefully.
Xu You is responsible for temperature control, so that the material can always remain within the superconducting critical temperature range.
Lin Shi adjusted the external magnetic field to separate the new iron element from other iron oxides.
With the help of a powerful magnetic field and the superconducting state, Xu You and Lin Shi finally completed the separation of matter.
After completing the separation experiment, Xu You carefully collected the powder of the new type of iron and observed their structure under a microscope.
"Well, after purification, the purity of the new iron has reached almost 100%. This new iron is really a special substance. Until now, I still don't know how it was formed."
Looking at the microscopic structure of the new type of iron on the screen, Xu You expressed his doubts.
But compared to Xu You's doubts, other people had far more doubts.
Seeing the images on the screen, the materials experts present were convinced that Xu You had indeed completed the purification of the new type of iron.
Many of them saw Xu You doing experiments for the first time, and they couldn't help but express their sincere admiration for Xu You.
"Professor Xu, you are truly amazing! You were able to predict the results of the experiment so accurately before even doing it. Compared to you, the gap between us is really huge."
Xu You shook his head and said, "Don't say that. I have also experienced countless failures when doing experiments. It is through these failures that I have gradually accumulated successful experience."
Xu You didn't want others to think of him as a genius who never failed.
Xu You knew that although he had the support of the system, the time and effort he actually put in were several times or even dozens of times that of others.
Xu You feels that this kind of unremitting perseverance and persistence is something more valuable.
After a pause, Xu You continued:
“Also, the success of this experiment is inseparable from the contribution of Professor Lin Shi. If it weren’t for her several important suggestions, we probably wouldn’t have found a way to solve the problem.”
Lin Shi was somewhat flattered to be praised in public by Xu You.
Xu You deliberately praised Lin Shi in front of everyone. In addition to praising himself, he also wanted to improve Lin Shi's status in everyone's mind.
This girl really deserves more attention from everyone.
After completing the purification of the new type of iron, Xu You carefully collected the powder of the new type of iron and prepared for the next experiment.
Due to the limited amount of ore, Xu You only purified one hundred grams of the new iron element in the first experiment.
However, this number is already considered a luxury for some basic research.
Xu You immediately gathered everyone together to plan the next research work.
"Then let me tell you my personal thoughts first."
This time, Xu You did not act too humble and took the initiative into his own hands.
Naturally, everyone had no objection to this and waited quietly for Xu You's next speech.
"Because the amount of new iron is very limited, I suggest that we first conduct a comprehensive study of its properties. In order to improve the efficiency of the research, each of us must have our own tasks. In the next period of time, we will be very hard-working."
