Zhang Daoxuan has been broadcasting live since three days ago, and most of the time the broadcast is almost completely still.

But even so, the popularity of his live broadcast room is still not low at noon or night, and tens of thousands of onlookers have spoken.

It turned out that he was doing the so-called room-temperature superconductor LK99 copper instead of apatite.

Before the live broadcast, he didn't expect that he, a pure scientific research migrant worker, could attract such a lot of heat by burning stoves all day long.

And today, at this moment, there are more people in the live broadcast room.

The popularity is about to exceed 100,000, and the number of online users has exceeded 20,000.

Just because, his sintered LK99 is about to come out.

Zhang Daoxuan was a little nervous, and he no longer looked at the barrage of arguments in the live broadcast room.

He rubbed his hands together and put on a brand new pair of nitrile gloves.

"Ding!"

The furnace finished counting the last seconds, Zhang Daoxuan waited for the temperature to drop to the safe operating temperature, and opened the door.

In the very center of the furnace lies a ruptured test tube.

The gray-black substance in the test tube is probably copper instead of apatite LK99.

Zhang Daoxuan was careful when he took out the test tube.

Although the news all over the sky says, "I don't understand room-temperature superconductors, but I understand the people of the Southern Dynasty!" ”

But Zhang Daoxuan still has a sense of excitement about the great changes at the forefront of science.

He was not convinced that this was really a room-temperature superconductor, and from the beginning he felt that the only way to test the truth was the experimental results.

However, he is an ordinary scientific researcher in such a not-so-top-notch university, and it is really the first time for him to be so involved.

Even if it's just a random assignment by the instructor.

Zhang Daoxuan took out the glass test tube and picked up the sample with tweezers.

The barrage is all about:

"Hurry up, hurry up and test if the resistance is 0, don't ink"

"Magnets, magnets! Let's test the diamagnetism!"

"Do you believe in the people of the Southern Dynasty? Scold! Scold! Oh!"

Zhang Daoxuan placed it on the operating table and tested it with a neodymium magnet first, and the sample remained motionless.

"Look! Sure enough! Don't move!"

"You know a hammer, such a big piece is too low in purity, you put a brick on a magnet the size of a finger cap, and the brick will float?"

Zhang Daoxuan also knows that there will be a lot of impurities, and it is not easy to test the phenomenon he wants to observe.

He began to carefully disassemble the sample using professionally trained techniques.

According to the principle described in the preprint, the superconducting properties of copper instead of apatite are derived from the one-dimensional microstructure of the crystal.

Now there may be no one on the whole earth who knows how stable this structure is, and whether it will be destroyed by a little external force at will.

Zhang Daoxuan also held his breath here, separating a little bit by little.

The tiny particles may be smaller than the dust floating in the air in an ordinary environment.

After Zhang Daoxuan's side was almost decomposed, he began to put the sample under the electron microscope.

He adjusted the focal length to almost see most of the sample, and placed the neodymium magnet under the glass slide.

The "powder" of the first samples, all wiped out, did not show diamagnetism.

"Look! Look! Failed!"

"If someone can successfully drill wood for fire, does that mean you can do it once?"

"Look at the people who are engaged in room-temperature superconductivity, it's either Ah San, or the people of the Southern Dynasty, what virtues do they have?"

Zhang Daoxuan carefully took down the slide and put it on the left-hand side, and then took a new slide with a sample on the right-hand side to continue the test.

There are still no diamagnetic particles.

Zhang Daoxuan was not discouraged.

Doing experiments is a test of mentality.

Sometimes the experiments that want to be replicated are the results of 200 years ago, and the theory and preparation steps are also clear, but the failure will still fail.

When Zhang Daoxuan had not yet entered the laboratory to work, his temper was also very irritable.

But in recent years, he has become more and more stable.

Third slide.

Fourth slide.

Fifth ......

Sixth ......

The last tenth......

There was a wail in the barrage at this time:

"Three days! Three days! I've been on guard for three days, and that's it? That's it? That's it?"

"Hahaha! It's all clowns!"

"Stocks! I've got to get rid of the stock!"

Zhang Daoxuan was in this barrage, continuing to repeat the steps he had done many times.

The neodymium magnet is getting closer......

This time, there seemed to be something moving in the electron microscope, but it was a little blurry.

Zhang Daoxuan locked the area that had changed just now and adjusted the focus.

His eyes were watching the clear display of the electron microscope, and the camera of the live cell phone was also pointing towards this end.

He approached the magnet, and one of the samples that covered the field of view of the electron microscope really moved.

It was originally lying flat, but it stood up little by little.

"Stand! Stand!"

"Superconductors have been discovered! Superconductors have been discovered!"

"Hehe, if I throw a magnet slag on the ground, I can stand up!"

"Hurry up and turn over the magnet in your hand and try to change the magnetic pole! Urgent! Urgent! Urgent! Hurry!"

Zhang Daoxuan took the magnet in his hand away, and then turned it over, and in the sample of this layer of the slide, a small piece stood up again, did not show paramagnetism, and was attached to the slide.

"Wuhu! Wuhu!"

"Go down in history! Go down in history!"

"I'm really about to admit that the people of the universe are the people of the universe!"

"Test the resistance! Test the resistance!"

Zhang Daoxuan found that he had really prepared LK99 copper to replace apatite, and his breathing was a little heavy.

"I've got to pick it out!"

Zhang Daoxuan used tweezers to peel off the other samples on the slide little by little, round and round, and finally left only the one particle that successfully demonstrated diamagnetism.

But at this moment, the door of the laboratory suddenly opened, and a senior brother wearing a white coat, who looked to be about thirty years old, and was young and bald, walked towards Zhang Daoxuan.

He walked fast, as if with the wind.

Zhang Daoxuan, who was engrossed, didn't notice that someone came in.

"Hey! How's the experiment going? Did you find the room-temperature superconductor that the stick said? ”

Zhang Daoxuan's shoulder was suddenly patted, he shivered, his whole body reacted with stress, the tweezers in his hand flew out uncontrollably, and the glass slide was also accidentally knocked away by him.

I said...... "When the man is going to say something."

Zhang Daoxuan pounced on the sample, as if he wanted to hold down such a sample, which was not much bigger than dust.

"It's over! It's over!"

"Who is this man! Is there a bit of scientific literacy?"

"There is no proof of death!"

"Script! Script!"

"It's really good to act......

Zhang Daoxuan pounced, and he didn't know how much LK99 copper he had inhaled to replace apatite in his nose and mouth.

Just when he fell to the ground and found nothing.

The senior brother suddenly roared in panic, "You! You! You! ”

He kept backing away, knocking down the phone that was broadcasting live.

The audience in the live broadcast room, after a shake, saw Zhang Daoxuan, who had been haunting the live broadcast screen for the past three days, from the perspective of sticking to the ground, and no body touched the ground, and the whole person floated.

"Lying ......"
