Chapter 258
"Don't go gentle into that good night!"

"Don't go meek into that good night."

This is a poem quoted in "Interstellar", and it is the same when used in scientific research competitions.

Competition is everywhere.

Everyone must be on guard.

Shen Guanglin and Manstein teamed up to challenge John Walker of England, intending to snatch scientific research results in this direction, but John Walker didn't know anything and was slowly advancing his scientific research ideas.

At the other end, Manstein's colleague, Zhang Shousheng's postgraduate teacher, and a physics professor at the Free University of Berlin, Mr. Lucas, is secretly collecting Shen Guanglin's ideas and challenging Shen Guanglin.

The news that Shen Guanglin accidentally leaked was used.

Shen Guanglin wanted to pretend not to know, because Lucas actually walked in another "correct" direction.

If he had a convulsion and had an idea, instead of polishing the graphite flakes, he would use glue instead, then things would be a big deal, and Shen Guanglin would probably be so depressed that he wanted to die.

Hurry up and launch the C60, I really can't wait any longer.

To keep Lucas busy.

Shen Guanglin searched for a long time, but couldn't find football ene that exists in nature. It seems that Sumio Iijima was also lucky at the beginning.

Then prepare it manually

In fact, it is not difficult to artificially prepare footballene, and Shen Guanglin has long known the method of laboratory preparation.

He didn't want it to appear so early at first, but now in order to prevent Lucas from discovering another material --- graphene, he can only let footballene appear in advance.

It is not complicated to prepare footballene in the laboratory, the most important thing is actually "creativity".

What Shen Guanglin lacks most is creativity, he is already overflowing with creativity.

Of course, most people would not think that what they would produce would be footballene, and all of this was slowly explored.

To prepare footballene, first prepare an arc chamber, then evacuate the arc chamber into a vacuum state, and feed inert gas such as helium or argon as the filling gas.

The next step is to place the cathode and anode materials in the arc chamber.

As Mr. Lu Xun wrote, there are two trees in the yard, one is a jujube tree and the other is also a jujube tree.

In the arc chamber, one cathode material is a graphite rod and the other anode material is also a graphite rod.

In order to have a higher probability of producing football ene, a catalyst must be added. Generally, some baht, nickel, copper or tungsten carbide is added to the anode electrode as a catalyst, so that the conditions are met.

The next step is to energize the electrodes.

When two high-purity graphite electrodes approach each other and arc discharge, the carbon rods will vaporize to form plasma.

Under an inert atmosphere, gasified carbon molecules will form stable fullerene molecules after multiple collisions, mergers, and closures.

When the process reaches a certain stage, a layer of soot will accumulate on the wall of the arc chamber. If the soot is collected, footballene can be extracted from it.

Even if the soot prepared by this method is not purified, the content of graphene is very high.

Of course, this method cannot be used in industrial production, and the incomplete combustion method must be used. Incomplete combustion of carbon in a high-temperature and high-pressure environment will also turn into football ene.

The method of preparing graphene by the electrode method is also very useful, and it has been used for 20 years.

But Shen Guanglin didn't intend to take it out immediately. He had to finish the theoretical work first, and then let the experiment verify its existence. After all, he also wanted to give Lucas a chance to see and compete.

Shen Guanglin pretended not to know what Lucas was doing, and followed the steps of the "plan" by himself.

In the beginning, I pretended to experiment with everything.

Facing Lucas who came to visit from time to time, he still enthusiastically introduced his "fruits of labor": What did he do with the electron microscope today? It's really interesting.

Lucas also replied: "GREAT JOB!"

According to Zhang Shousheng, Lucas's physics laboratory is polishing graphite sheets every day, just to study what the state of graphite will be when it is extremely thin.

What state will it be?Graphene, of course.

If you really find graphene for you, labor and management will not be able to live.

Shen Guanglin called Xiao Lincheng across the ocean and asked him about Iijima Sumio's news.

Soon, Shen Guanglin got the third-hand information of Iijima Sumio: the onion-shaped structure diagram of fullerene published in Fuso domestic magazines.

At the same time, there are some obviously wrong explanations and assumptions in it.

Of course, Shen Guanglin knew that Iijima Sumio's assumption was wrong, and he, Shen, needed to re-imagine a correct result.

Knowing the composition and structure of C60, it is not complicated to perform theoretical calculations.

Shen Guanglin is about to start "fabricating" scientific research results.

Start with a picture, and the content depends entirely on editing.

Shen Guanglin used the "results" he knew to deduce the cause of this phenomenon, and it really fit perfectly.

He first drew the molecular structure diagram of C60, then calculated the force bonds between atoms, and then looked for equations to model, and deduced what is the onion-like thing?
With a bald head, everything is not difficult.

The theoretical calculation is completed in half a day!

After confirming that it is correct, you can write the results paper next.

Shen Guanglin's sword is not old.

In just two days, Shen Guanglin's thesis has been finished and ready for publication.

Time to "tip" some news to Lucas and keep him "busy".

Everyone else was busy doing experiments, and Shen Guanglin played a ball game.

He used 60 small balls and small sticks of equal length to tie a ball, then found the angle and took pictures with the camera.

After the photo is developed, compare it with Iijima Sumio's diffraction pattern.

Adjust when it doesn't look like it, adjust it when it doesn't look like it
Until, the photos he took and Iijima Sumio's diffraction pattern were almost completely matched.

perfect!

Shen Guanglin is not an annoying person, because he likes to invite everyone to dinner from time to time, sometimes he does it himself, and sometimes he finds a restaurant with a good environment.

Although he was only temporarily working in West Berlin for a period of time, Shen Guanglin still rented a high-end apartment.

As long as the laboratory completes a small node, Shen Guanglin likes to invite everyone to eat and drink.

The oriental delicacy that foreigners like most is dumplings. Shen Guanglin also knows how to make dumplings, although Wu Xiaoyun is the best at it.

On this day, taking advantage of Lucas' visit again, Shen Guanglin announced that he would invite everyone to dinner. This time he would not cook it himself, but would also invite everyone to eat the most luxurious Turkish meal, preferably with French foie gras and black truffle.

"What's so happy?" Lucas asked everyone's question.

"I think I have completed another major discovery in physics?" Shen Guanglin pretended to be very excited, but fortunately Lucas hugged him and felt the stiffness of Lucas' body.

"What major discovery?" Lucas was in disbelief.

"I discovered a macromolecule made of carbon atoms that exists in nature!"

While speaking, Shen Guanglin took out the diffraction diagram that Sumio Iijima had made: "This is a diffraction diagram taken by a scientist in Fuso when he was studying an optical microscope. He didn't take it seriously, but I think this structure is very weird. , should be a large molecule. Sure enough, through my demonstration, it is indeed a large molecule, and it is a three-dimensional structure composed of carbon atoms."

"what?"

Lucas was so jealous that Shen Guanglin was busy every day, and he actually found out the important person.

I have "followed" him for so long, and I have no idea what to do.

"This is a space structure composed of 60 carbon atoms. I have carried out theoretical calculations, and the result proves that it is a perfect sphere with very stable performance."

Shen Guanglin took out the ball he had pierced, and compared the diffraction pattern of Iijima Sumio.

"Let's take a look, they are exactly the same, they are exactly the same!"

"Congratulations, Shen." Manstein was the first to congratulate.

"Accidentally, it's just a fluke, it's just a fluke."

"Mr. Shen, it's amazing! Your metaphysics is working again!" Wu Xiaoyun also gave a thumbs up. She is used to it. No matter what Shen Guanglin does, it will produce results.

Lucas didn't smile, he pretended to be calm and asked, "Have you observed this substance on the electron optical microscope?"

"Not yet. I'm planning to go to Fusang after I'm busy to see where Sumio Iijima got this material. I tried many kinds of materials, but I couldn't find any."

Shen Guanglin pretended to be very distressed, "I'm afraid I have to share the results with others."

"This is also worthy of congratulations! You have completed at least 80% of the work, why don't you spend more time looking for it yourself? Then the result will be your own."

The meaning in Lucas' eyes is indescribable.

"Makes sense!"

Shen Guanglin agreed with Lucas' point of view.

Everyone had a great time that night. Lucas may have something to do at home and left early.

The next day, Shen Guanglin wanted to chat with Lucas.

Coincidentally, Lucas was on a "business trip" and didn't know where he went.
