Chapter 457 Invitation to the Nobel Prize Dinner

After the frost, the weather in Jin Ling was much colder. Although it hadn't entered winter yet, it was better than winter's cold.

At this moment, on the campus of Jinling University, in a certain office of the School of Materials Science and Technology, there is a dense mist floating on the thermos cup on the desk.

Professor Li Rongen, who was sitting at his desk, was browsing the meeting information on the computer while drinking hot tea.

It will be the annual MRS autumn meeting soon, and the papers that will be reported at the meeting have been released one after another.

No matter whether you have time to go to the site or not, this top summit in the field of materials science is something that any material person will pay attention to.

Judging from the trend of paper submissions, research in the direction of graphene has shown a blowout growth this year.

The most striking of these is undoubtedly the paper on the research on graphene superconducting materials.

101K!

The sensation caused by this number in the material science community can be described as a tsunami.

If you sort the papers with the highest number of downloads, this paper, which was put on the official website after the deadline, is rising to the top three at an incredible speed.

Although Li Rongen is not in the direction of superconducting materials, and even knows little about graphene materials, he mainly studies carbon nanotubes, but this does not prevent him from understanding the things described in the paper and realizing the awesomeness in it. force……

After reading the paper from beginning to end, Professor Li Rongen put down the paper in his hand and couldn't help but sigh with emotion.

"sharp."

Graphene superconducts.

This concept was still an unattainable dream a few years ago. I did not expect that the breakthrough from the theoretical level to the application level was completed in just a few years.

Not only that, judging from the content described in the paper, the superconducting transition temperature of 101K has not reached the limit.

In theory, as long as the carrier concentration of graphene continues to increase, this number can be made even higher...Of course, this seems easy to say, but it is definitely not easy to do.

In any case, people who do research on superconducting materials in the direction of copper oxides may doubt their lives after reading this paper.

After all, it took them half a century to raise the critical temperature of superconductivity to around 125K. The advantages of graphene in terms of plasticity and engineering performance are enough to blow it up.

It seems that Professor Lu is no longer satisfied with turning the lithium battery field upside down.

Batteries, superconductivity, what's next?

Professor Li Rongen is only curious about one thing now, what is this guy going to study next?

It seems that as long as it is a field that he is eyeing, it will definitely be subverted by him in the end.

It is not only Li Rongen who is also reading this report, but also the doctoral and master students he leads.

Hearing the professor's sigh, the doctor named Zhang Fan pushed his glasses, couldn't hold back the curiosity in his heart, and asked with a look of worship: "Professor, when you took Lu Shen to do experiments, what kind of person was he?" what?"

Hearing this question, Professor Li Rongen smiled.

"What kind of person? Apart from being a genius, I don't know how to describe him to you."

After a pause, recalling the past, Professor Li Rongen continued.

"I won't talk about the results of the Mathematical Modeling Contest. You probably have heard of it. He was able to build a model based on the experimental data provided by me when he was a sophomore, and calculate the mechanical properties of the product based on the data collected by the Fourier transform infrared spectrometer. How much technical content there is, you can figure it out for yourself.”

After hearing this sentence, not only Zhang Fan who asked the question, but also the other two graduate students in the office were moved.

It’s okay to be able to calculate materials science. Many experiments in materials science now use first-principle calculations, especially after Jin Da came out of Lu Zhou, even if they don’t engage in this direction, they still understand a little bit now.

But being able to do this in a sophomore year is really terrifying.

As for the Higher Education Society Cup...

For salty fish like them, it is very satisfying to be able to win a national award in the digital simulation competition, whether it is the first or the second year of the country.

Thinking of how awesome his juniors are, Zhang Fan couldn't help but reflect on what he was doing in his sophomore year.

However, after thinking for a long time, he couldn't think of anything except the name of his ex-girlfriend.

Seeing the expressions on the faces of his students, Professor Li Rongen guessed what they were thinking, and just shook his head with a smile.

"Don't be envious, that kid is a genius in mathematics. Not long after he won the Higher Education Society Cup, he solved a world problem in the field of number theory... It seems that Zhou is guessing or something. You haven't seen him before, you may feel that I don’t know how strong his mathematical intuition is. To put it simply, if you throw a set of data at you, I’m grateful that you can draw a picture, but if you throw it at his hands, he can conjure flowers for you Come."

Several students looked at each other.

They obviously didn't understand what Professor Li Rongen said about conjuring flowers, what kind of show operation it is.

While talking, Pei Qing, who had been silent all this time, also finished reading the thesis and looked away from the screen.

"Professor, why do you think Professor Lu went to study superconducting materials? Does this thing have industrial application prospects?"

Li Rongen: "He didn't necessarily study this because of the prospect of industrial application, but if you have to talk about the prospect of industrial application, its application prospect may be much bigger than you imagined."

Pei Qing was slightly stunned, and asked in doubt: "Is the market for superconducting materials so big?"

Professor Li Rongen shook his head with a smile: "Its significance is not only about superconductivity."

Hearing this, Zhang Fan was also stunned: "It's not just superconducting?"

"If you don't understand, read the paper again and you will understand. The existence of Mott insulator means that graphene can be 'opened' or 'closed' under certain conditions. What does this mean? Need I say more?"

Pei Qing's expression was slightly moved: "...semiconductor?"

Professor Li Rongen nodded approvingly, "Correct answer."

Graphene has broad application prospects in the field of transistors and other electronic devices due to its high charge carrier mobility.

However, it is well known that graphene has no bandwidth, resulting in graphene electronics remaining highly conductive at any gate voltage and unable to be completely turned off, thus limiting its application in electronic devices.

However, the particularity of Mott insulators causes electrons in the graphene superlattice to pass quickly from the initial insulating state under the condition of applying a gate voltage to the material, as if there is no resistance.

There is no doubt that this is an "on and off" state.

Just using the properties of this layer of Mott insulator does not require the entire system to be at a low temperature of 101K to realize the superconducting transformation of the entire material.

Therefore, the significance of this paper is not only the application in the field of superconductivity, but also opens up a new platform for the research of graphene semiconductors.

It is estimated that at the MRS conference, not only the energy industry is interested, but major electronics manufacturers will also follow up the research in this area.

After all, the price of graphene is sold in terms of grams. It is too wasteful to use it for power transmission, but it is acceptable to use it in electronic products.

At this moment, the browser on the taskbar at the bottom of the desktop suddenly flickered.

Seeing the reminder of a new email, Professor Li Rongen clicked on the mailbox.

When he saw this email, he couldn't help being slightly stunned, and then a gratified smile appeared on his face.

"This kid hasn't forgotten me."

Invitation to the Nobel Prize Ceremony.

He originally planned to watch the grand event on TV, but unexpectedly, he had the opportunity to go to the scene...
