Chapter 171 My goal is far more than that
Once upon a time, Ning Chen’s biggest wish was that one day he could truly achieve financial freedom.
In this case, Ning Chen no longer has to run around for money and can do what he likes as he pleases.
But even so, Ning Chen will not slack off in scientific research just because he has enough money.
On the contrary, now that he no longer has to worry about money, Ning Chen can study the scientific field he wants to study with more confidence.
Seeing that Ning Chen's expression was a little dull, Xu Zhou thought that Ning Chen was not ready to accept this huge sum of money, and quickly explained:
"Ning Chen, actually this money is not as much as you thought. According to the provisions of the contract, the patent license fee is paid on an annual basis. After the school deducts 20%, we still have to pay nearly half of the personal income tax. In this way, we only have the money we receive in a year. More than three million. "
Of course, the annual income of more than three million is no longer a small amount, but compared with the apparent amount, there is still a relatively large psychological gap.
"Teacher Xu, I know this. But no matter how much money we can get, scientific research work still has to continue."
Xu Zhou was a little surprised to find that Ning Chen now His mood was surprisingly calm.
You know, when Xuzhou first learned the news, he was so excited that he almost started dancing with his hands and feet.
"Yes, it is true. We need to make money through scientific research, but making money is definitely not the ultimate goal of scientific research. Ning Chen, no matter what level we reach in the future, we should never forget to do scientific research "
Xu Zhou rarely spoke to Ning Chen so seriously, and Ning Chen nodded seriously when he heard this.
“Don’t worry, Teacher Xu, I will never forget my original intention of doing scientific research.”
“Well, that’s good. The three-year contract we signed with Piati The patent license period is more suitable for both parties. If these achievements cannot withstand the test of the market, Piati's losses will be relatively small. If these achievements indeed show great market value, wait until three. After this year, we can also negotiate with Piati for a higher amount of patent licensing cooperation.”
Ning Chen also felt that such a term was more appropriate. The contract term signed for the first time would definitely be shorter, and the market would have to first evaluate the specific value of the patent.
“Ning Chen, when you came to the laboratory today, are you preparing to start a new research project?”
“Yes, after more than one semester at Yanda, I feel that I have already We have broken through the previous bottleneck in materials science. Teacher Xu, I want to continue to study iron-based superconductors on the basis of the previous work."
As he said this, Ning Chen presented his existing experimental ideas to Xu. Zhou started to explain.
After listening to Ning Chen’s thoughts, Xu Zhou also felt that there was indeed a lot of room for exploration in these directions of Ning Chen.
"It seems that you really gained a lot from going to Yanda this time."
From Ning Chen's thoughts, Xuzhou could also feel the changes in Ning Chen during this period.
Previously, Ning Chen thought more within the field of materials science itself, supplemented by some mathematics for modeling and calculation.
But after returning from the exchange study at Yanda, Ning Chen was able to think more from the perspective of physics and chemistry, which suddenly broadened his thinking.
"Okay, Ning Chen, just conduct the experiment according to your ideas. If you have any questions, just discuss it with me at any time."
However, Xu Zhou felt that with Ning Chen's current ability, there shouldn't be too many problems that need to be discussed with him.
In the field of research on iron-based superconductors, Ning Chen is already at the top level in the world.
After telling Xu Zhou about his experimental plan, Ning Chen began to prepare for the experiment.
The first direction Ning Chen wants to study is the various changes in iron-based superconductors under ultra-high pressure.
These changes are mainly changes in the superconducting critical temperature of iron-based superconductors.
In previous experiments, some superconductors have experienced an increase in their critical temperature under ultra-high pressure.
Ning Chen felt that this situation would also occur in iron-based superconductors, so he decided to start research from this angle first.
Of course, this is not Ning Chen’s ultimate goal, because the significance of research on this type of topic is relatively limited.
Ning Chen hopes to use this research to better understand the nature of iron-based superconductivity and to verify some of his previous guesses.
After preparing for the experiment, Ning Chen went to the ultra-high voltage equipment laboratory of the measurement center, constructed the superconducting circuit, and began to measure the superconducting properties of materials. In a few days, Ning Chen completed a number of experiments measuring the superconductivity of iron-based superconductors under ultra-high pressure.
The results of the experiment are also very consistent with Ning Chen’s previous expectations.
Most of the iron-based superconductors have superconducting critical temperatures under ultra-high pressure, ranging from several K to more than ten K higher than before.
Just this measurement result, if sorted out carefully, is enough to publish a fairly good paper.
Of course, Ning Chen’s goal goes far beyond this, and this measurement work is just an introduction to the entire subject.
Before the end of the ultra-high pressure measurement experiment, Ning Chen carefully summarized and analyzed the data obtained in the past few days, and constructed the corresponding model in the computer.
Ning Chen knows that the application value of superconductivity of materials under ultra-high pressure is very limited, because ultra-high pressure conditions are very difficult to achieve, and even more difficult to maintain than low-temperature conditions.
The most important thing is to get some essential superconducting mechanisms from it, so that Ning Chen can more thoroughly understand the principles of each superconducting process.
"Huh? Wait a minute, I seem to have figured out the essential reason for the increase in the superconducting criticality problem of matter here..."
After Ning Chen continued to study various data, suddenly There was a feeling of enlightenment.
Ning Chen feels that ultrahigh pressure is not the essential cause of the increase in the superconducting critical temperature of matter, but is only a direct cause.
“The most essential reason for this phenomenon is the compression of the volume of matter. Analyzed according to this idea, if some atoms in the iron-based superconductor are replaced with atoms of a smaller radius, theoretically It is possible to continue to increase the superconducting critical temperature of matter..."
Thinking of this, Ning Chen became excited.
However, Ning Chen also knew that this was just a theoretically feasible idea. In actual research, various problems would arise.
The first thing Ning Chen could think of was that the atoms to be replaced should preferably be elements belonging to the same system as the previous atoms, because this would ensure that the two elements have similar properties.
Otherwise, simply reducing the radius of the atom, even if it can reduce the volume of the substance, will affect other properties of the substance.
In this way, let alone whether the newly synthesized material will have a higher superconducting critical temperature, it may not even be a superconductor.
Following this idea, Ning Chen listed all possible replacement atoms and formulated the next research plan.
......
In the following days, Ning Chen conducted research on atomic replacement of various iron-based superconductors according to his own experimental plan.
Since these studies had not been done before, Ning Chen did not have much to learn from and could only rely on himself to explore bit by bit.
The entire experimental process did not go smoothly, but Ning Chen had already been mentally prepared and was not affected by the difficulties he encountered. He continued to study this topic with patience and perseverance.
During this period, Ning Chen also "smoothly" completed the final exams for each subject this semester.
Ning Chen did not invest too much energy in these exams. He only spent a little time before the exam to review various professional courses and directly copied some textbooks for liberal arts exam subjects. I memorized it directly.
Ning Chen's final exam this semester is equivalent to studying for the exam in the first semester. After completing the exams in these subjects, the master's degree study course is almost over.
Ning Chen planned to pass all the doctoral subject examinations in the next year, and then prepare for the final graduation defense.
The sooner you graduate with a PhD, you will be able to stay in school earlier, and it will be more convenient to start scientific research projects.
On this day, Ning Chen learned a piece of good news.
Xu Yang, a student taught by Ning Chen before, scored 608 in the college entrance examination and 130 in mathematics.
Ning Chen was also a little surprised by Xu Yang's score, which even exceeded Ning Chen's college entrance examination score that year.
