Chapter 531 Successful separation!
Compared to liquid nitrogen, liquid helium can reach lower temperatures.
Under the premise that the superconducting critical temperature of the material is not yet known, using liquid helium as the coolant is definitely a safer way.
Xu You seemed to be very sure of the superconducting critical temperature of matter and directly gave up liquid helium as a coolant.
"No need, the new iron does not need such a low temperature to achieve superconductivity. If it is not necessary, there is no need to waste more expensive coolant." Xu You said with a smile.
"Okay, teacher."
Although normally speaking, when the properties of substances are unclear, you should be fully prepared.
However, since Xu You has 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 have been too many things that Lin Shi couldn't understand about Xu You. Lin Shi felt that this might be the gap between ordinary people and geniuses.
The other materials experts present were curiously observing the progress of the experiment.
They all know that Xu You's achievements in the field of superconductivity are second to none in the world, and it was by virtue of his research in this field that Xu You won China's first Nobel Prize in Physics.
However, they did not dare to believe that Xu You could accurately determine the superconducting critical temperature of the new type of iron before successfully purifying the new type of iron.
After a simple exchange, Xu You and Lin Shi continued to conduct their experiments as if no one else was around.
The task of cooling down may seem simple, but lowering the temperature quickly and accurately, just like a chef's control over heat, cannot be accomplished overnight.
Xu You started practicing these operations before he became an official student of Jijing University.
It is precisely because of thousands of experiences that Xu You can control the temperature drop so skillfully and accurately.
Although there is some gap between Lin Shi and Xu You in terms of ability, she is no less diligent than Xu You.
"Lin Shi, we are almost reaching the critical temperature of superconducting, we need to slow down."
"Okay, teacher."
Xu You realized that the temperature at this time was very close to the superconducting critical temperature of the new type of iron, so he quickly slowed down the cooling rate.
Even if Xu You is very confident about his simulation, there may still be some errors.
Just then.
Xu You and Lin Shi saw at the same time that the current data on the testing instrument had undergone tremendous changes.
Such a huge change can show that the resistance of the metal material has reached a very small value.
Because in addition to the new type of iron, there are other impurities in the measured substance, which makes the entire material not strictly a superconducting material.
But such changes are enough to prove that Xu You's prediction is completely correct.
"Teacher, your prediction is right!"
Seeing such an 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.
For Xu You, Lin Shi had only infinite admiration.
On the other hand, Xu You did not have any emotional fluctuations because of his accurate prediction, and continued to speak calmly:
"Lin Shi, prepare to apply an external magnetic field to separate the matter."
"Okay, teacher."
Next, Xu You and Lin Shi Xu You performed their respective duties and conducted experiments carefully.
Xu You is responsible for temperature control to keep the material within the superconducting critical temperature range.
Lin Shi, on the other hand, adjusted the external magnetic field to separate the new iron element from other iron oxides.
With the powerful magnetic field and the blessing of the superconducting state, Xu You and Lin Shi finally completed the separation of matter.
After completing the separation experiment, Xu You carefully collected the new iron powder and observed their structure under the 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 don't know how it was formed."
Looking at the microstructure of the new type of iron on the screen, Xu You expressed his doubts.
But compared to Xu You's doubts, there were far more doubts in other people's minds.
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.
It was the first time for many of them to see Xu You's experiment with their own eyes, and they couldn't help but express their sincere admiration for Xu You.
"Professor Xu, you are really amazing! You are able to predict the experimental results so accurately before doing the experiment. Compared with you, the gap between us is really huge."
Xu You shook his head when he heard this and said: "Don't say that. I have experienced countless failures when doing experiments. It is precisely based on these failures that I have gradually accumulated successful experience."
Xu You doesn't want to think of himself as a genius who never fails in other people's minds.
Xu You knew that although he had the blessing of the system, the actual time and effort he put in were several times or dozens of times that of others.
This kind of long-lasting perseverance and perseverance, Xu You feels is the more precious thing.
After a pause, Xu You continued:
"Also, the success of this experiment is also inseparable from the contribution of Teacher Lin Shi. Without her several important suggestions, we may not have found the direction to solve the problem yet."
Being praised by Xu You in public, Lin Shi was a little flattered.
Xu You deliberately praised Lin Shi in front of everyone. In addition to the praise itself, he also really wanted to improve Lin Shi's status in everyone's minds.
This girl really deserves more attention from everyone.
After completing the purification of the new iron, Xu You carefully collected the powder of the new iron and prepared for the next experiment.
Due to the limitation of the quantity of ore, Xu You only purified 100 grams of the new iron element in the first experiment.
However, this amount is considered quite luxurious for some basic research.
Xu You immediately called everyone together to plan the next research work.
"Then let me tell you my personal thoughts first."
This time, Xu You did not show too much humility and put the leadership in his own hands without hesitation.
Naturally, everyone had no objections to this and were quietly waiting for Xu You's next speech.
"Because the number of new irons is currently very limited, I suggest that we first conduct a comprehensive study on the properties of new irons. In order to improve the efficiency of research, each of us must have our own tasks. In the next period of time, we will be very
Hard."
