If it is bent, it means that this thing can be used to make wires.
He watched helplessly as the originally straight black cylindrical object was bent with force. To say that Zhao Sheng was not excited would be a lie.
After all, he was "deceived" by Lin Xiao just to create this high-temperature superconductor that could be bent.
Among the high-temperature superconductors currently discovered in the scientific community, that is, superconductors with a critical superconducting temperature above 77K, they are basically copper oxides, which can also be called cuprates. These things themselves are relatively brittle and have poor toughness.
.
If the thing they built today could really bend, hey, if nothing else, they could make a lot of money.
Oh, this thing belongs to Lin Xiao. If it really makes money, it has nothing to do with him.
Thinking of this, Zhao Sheng immediately lost his mind. Of course, then he felt happy again. Even if making money had nothing to do with him, he would still be able to get some related awards in the future if he didn't talk about it.
Just for the National Natural Science Award, the first prize is definitely guaranteed.
Of course, the premise is that the superconducting critical temperature of this thing really reaches above 77K.
Just when I thought of this, I saw the two people who had gone to get the liquid nitrogen come back and shouted: "The liquid nitrogen is here!"
"Okay, let's do the experiment quickly!"
Zhao Sheng couldn't wait any longer, then turned to look at Lin Xiao again and said, "Why are you not excited at all?"
"Well……"
Lin Xiao barely showed a slightly excited expression on his face.
But it was a little too forced, and Zhao Sheng couldn't help but roll his eyes: "Forget it, I won't ask you, I guess you don't care about this kind of high-temperature superconductor. Unless it is a normal-temperature superconductor, can you be excited?"
Lin Xiao touched his nose, maybe?
After all, after witnessing this room-temperature superconductor before, he had already done all the excitement he needed to do.
I just don’t know what the expressions on these people’s faces will be when they see this thing that can still maintain a superconducting state when the temperature gradually returns to normal temperature.
He suddenly had some expectations.
So soon, the test device was ready. It was not complicated at all. Anyway, it was just a temperature sensor, which was directly attached to one of the black solids, and then tested using the Meissner effect. This was the easiest way.
Then, they poured liquid nitrogen into it, and immediately, the number on the indicator meter connected to the sensor began to drop rapidly, reaching around 77K.
Then, put a small magnet on it, and suddenly the small magnet levitated.
Such a magical scene, in ancient times, could hardly be described as a magical skill.
"good!"
Seeing this scene, Zhao Sheng immediately shouted and then clapped.
And everyone else immediately followed suit and clapped.
This thing really meets the requirements of high-temperature superconductors!
This is undoubtedly an extremely exciting thing for them.
Why?
Because liquid nitrogen is cheap!
The price of liquid helium is about 200 yuan per liter, while the price of liquid nitrogen can be as low as 6 or 7 yuan per liter.
After all, helium is a rare gas, but nitrogen can be found everywhere. You must know that 78% of the earth’s air is nitrogen!
Therefore, the price of preparing nitrogen is very cheap.
Since the new superconductor they created can bend, it obviously has the value of large-scale use, such as superconducting maglev trains. In fact, the maglev train in Shanghai uses yttrium-barium-copper-oxide system superconductors.
In addition to this, this thing can also be used to generate electricity, that is, superconducting power generation. Yttrium barium copper oxide can be used to lay out the tracks of maglev trains because the tracks are very long and do not need to be very curved. But if it is to generate electricity
, because it needs to be wound into a coil, the very brittle yttrium barium copper oxide obviously cannot be used, and their new superconductor can play a role.
Or, it can even be used for superconducting power transmission. Of course, it can only be used in areas with high power consumption. The loss-free nature of superconducting power transmission can greatly reduce the power load.
besides……
The more Zhao Sheng and the others thought about it, they even thought about the superconducting electromagnetic gun.
Lin Xiao looked at their expressions as if they were lost in reverie and knew what these people were thinking.
He shook his head, he was still too young.
Just like this, until after a period of time, all the liquid nitrogen poured out evaporated, and the temperature of this new superconductor also began to rise.
77K,80K,85K……
Suddenly, someone noticed the gradually rising temperature and exclaimed: "It's 90K!"
Everyone looked over immediately and showed surprised expressions.
The temperature actually rose to 90K!
But the Meissner effect still exists, and the small magnet is still floating on it and constantly rolling.
"Holy crap! How is this possible?!"
Seeing this scene, Zhao Sheng opened his mouth wide. He has reached 90K, but he can still maintain a superconducting state?
Then he couldn't help but look at Lin Xiao and said: "Director Lin, you have created another history!"
Lin Xiao shrugged, looking indifferent.
Seeing him like this, Zhao Sheng became even more confused. Even if it was like this, why wasn't Lin Xiao even excited at all?
However, at this moment, someone next to me exclaimed: "100K!"
Zhao Sheng's eyes widened immediately, and he immediately turned to look at the indicator. The temperature had indeed reached 100K, but... the Meissner effect still existed!
This means that the long, black thing is still in a superconducting state!
He turned to look at Lin Xiao again, and once again couldn't help but exclaimed: "Lin Xiao, what's going on?"
Lin Xiao spread his hands, "Don't ask me, just keep reading."
Zhao Sheng looked quickly and saw that the temperature was still rising!
110K……120K……
Zhao Sheng was even more shocked, and instantly turned to look at Lin Xiao: "This time I want to say that you created a miracle!"
Lin Xiao shrugged and spread his hands.
140K.
"You...well, you created another miracle."
Lin Xiao waved his hand.
150K.
"You created... created... created a myth!"
Lin Xiao moved her wrist.
160K.
"Are you... a little unreasonable?"
Lin Xiao moved her fingers.
200K.
"What the hell, why?"
Lin Xiao was indifferent
…
273.15K.
0℃!
"..."
Zhao Sheng, as well as everyone present, stared in front of them in stunned silence.
The little magnet is still floating on the "black bar", spinning quietly, as if laughing at them:
Why add liquid nitrogen to me?
You can superconduct without liquid nitrogen!
"Impossible...impossible...impossible..."
Zhao Sheng began to murmur in his mouth, until finally, he rubbed his eyes and took a closer look at the thing to make sure that he had seen it correctly.
Then, he immediately turned around and came to Lin Xiao, then grabbed his shoulders and started shaking him, "Tell me, this is not true!"
"This is too crazy! How is this possible! This requires room-temperature superconductors!"
At this time, Zhao Sheng no longer looked like an old professor in his fifties.
Of course, other people in the room also reacted the same way, with disbelief on their faces.
What the hell is this a high temperature superconductor?
This is not scientific at all!
Damn it, why?
"Ahem, calm down, calm down."
Seeing Zhao Sheng's look, Lin Xiao felt relieved. Hey, he was almost surprised at first.
Now of course he is happy to see others looking so surprised.
Then he patted Zhao Sheng on the shoulder, put his hand down from his shoulder, and said with a smile: "It has reached this level, why can't it be a room temperature superconductor?"
Then, he took a hot air blower from the side and blew hot air on the thing.
Under the hot air, the temperature on the indicator quickly rose from 273.15K to 300K, a temperature of nearly 27 degrees Celsius.
The Meissner effect still exists.
Seeing this scene, Zhao Sheng was stunned again.
"this……"
He felt that his scientific outlook was shattered all over the place.
Room-temperature superconductors were created just like this?
Thinking back to just now, he seemed to be rejoicing that this was a high-temperature superconductor, but now, is this a normal-temperature superconductor?
Suddenly he came to his senses and asked Lin Xiao excitedly: "Did you already know this? No wonder you didn't react at all just now!"
"Tell me, how do you know? Didn't you say this was a high-temperature superconductor before?"
"calm down."
Lin Xiao patted Zhao Sheng on the shoulder and said with a smile: "Normal temperature superconductors are also high-temperature superconductors. I was right."
"You..." Zhao Sheng was speechless.
Room-temperature superconductors are indeed considered high-temperature superconductors, but academic circles generally equate high-temperature superconductors with cuprate superconductors. Who would have thought that a room-temperature superconductor would suddenly appear?
However, Lin Xiao did not give Zhao Sheng a chance to continue speaking. Instead, he turned to look at everyone in the audience and said, "Okay, everyone, as you can see, we have created a room temperature superconductor."
"I also know that everyone is very excited, but room-temperature superconductors are obviously strategic materials, and they must be kept strictly confidential before the decision is announced. It can be equivalent to the top national secrets."
"In other words, our project will be put on hold indefinitely, and someone will probably come to you to sign some higher-level confidentiality agreements."
"Of course, I know all of your contributions to this project, so you will all receive certain rewards in the future. You can rest assured about this."
Obviously, Lin Xiao's words now are to inoculate them. After all, the matter is very important. Of course, there is no need to worry about the character of those who can come to Dingguang Research Institute.
Needless to say, Zhao Sheng, the interns and assistant researchers all nodded, with serious expressions on their faces, and thinking in their hearts, after all, do they also count as people who know state secrets?
When Lin Xiao saw them nodding, he smiled slightly, then took out his phone and called Ma Gaoliang.
"Lao Ma, this is great news. Come to my research institute quickly. I'll wait for you here."
After saying that, he hung up the phone directly without waiting for Ma Gaoliang to speak.
His operation directly aroused Ma Gaoliang's curiosity to the top, so he didn't bother to call back to ask for details, and went straight to the Dingguang Research Institute without stopping.
Then Lin Xiao naturally showed him the magic of room-temperature superconductors, and Ma Gaoliang suddenly showed the same surprise as Zhao Sheng and others just now, or even more.
Because he knows how much the emergence of room-temperature superconductors will bring to the world!
All the technologies of the past will be eclipsed by this dark thing!
