It's April.

Huang Haojie has left the secret laboratory and came to the X-ray laser base in Luhe County.

"Boss, here's a report on the situation of our experiments these days, take a look." The equation handed Huang Haojie a stack of experimental briefings.

Huang Haojie glanced at the ongoing experiment, and then flipped through the experiment briefing.

From January 2018 to the end of March.

The X-ray base has carried out a total of 134 experiments of various sizes, with a total of 1,127 hours of X-ray laser use and a total cost of 2.9 billion yuan.

Experiments were carried out on iron-copper alloys, iron-lead alloys, carbon steels, copper alloys, iron-silver alloys, and so on.

Although these experiments did not bring a large number of practical results, they greatly promoted the basic science and materials science of Galaxy Technology.

Soon he discovered that in the case of iron-silver alloys, they mentioned short-lived superconducting properties in experimental materials.

This iron-silver alloy was deliberately inserted into the experimental project in order to draw out the next superconductor at room temperature

"Equation! Of the last ten alloy experiments I arranged, did this iron-silver alloy really show transient superconductivity?" Huang Haojie asked, pointing to one of the briefings.

"Yes! Boss, among the ten alloy experiments you explained, four of the iron-silver and iron-copper alloys showed short-term superconductivity properties, and the superconductivity properties of the No. 2 iron-silver alloy lasted for about 3 minutes. The equation replied with some excitement.

After all, this is a superconductor, and it can be a superconductor at room temperature.

The equation goes on to say:

"We then repeated the experiment twice and confirmed that all four samples showed transient superconductivity at room temperature."

Huang Haojie took out the experimental briefing of the No. 2 iron-silver alloy and took out the scratch paper.

The composition ratio of iron-silver alloy was adjusted to adjust six formulas.

Then, the laser power, magnetic field, air pressure, temperature, etc., of the experiment were readjusted.

"According to the experimental plan I designed, one experiment at a time."

After the equation took Huang Haojie's scratch paper, he nodded hurriedly:

"No problem."

……

After more than a week of intensive experimentation.

Huang Haojie and Equation looked at the experimental briefing that had been sorted out.

"Boss! I feel like we've entered the door of ambient superconductors. Equation looked at one of the experimental reports and said excitedly.

The iron-silver alloy in this report can maintain superconductivity at room temperature for more than 2 hours.

"It's still early! Have you ever noticed a pattern in the ratio of silver?" Huang Haojie listed the silver ratio among the six recipes.

The equation was quickly studied carefully, and the more I looked at it, the more I felt that there was indeed some kind of law in it.

Silver content 2% (41 minutes in room temperature superconductor state), 2.5% silver content (53 minutes in room temperature superconductor state), 3% silver content (62 minutes in room temperature superconductor state);

The silver content is 3.5% (83 minutes in the superconductor state at room temperature), the silver content is 4% (the superconductor state at room temperature is 141 minutes), and the silver content is 4.5% (the superconductor state at room temperature is 97 minutes).

"The normal temperature superconducting state of the obvious iron-silver alloy should be in the peak range of 3.5~4.5% silver." Equation looked up and said.

"That's right! Next, we will conduct more detailed experiments in the range of 3.5~4.5% silver content. ”

After Huang Haojie finished speaking, he and the two of them continued to refine the silver content ratio of the iron-silver alloy, as well as adjust the power, temperature, magnetic field, air pressure and so on of the experimental laser.

……

Buzzing...... With a faint whisper, powerful X-rays were destroying the iron-silver alloy inside the reactor.

With the cooperation of special magnetic field, temperature and air pressure, the physical properties of iron-silver alloy are quietly mutating.

Huang Haojie looked at the situation in the surveillance screen, and he knew that they were not far from a normal temperature superconductor that could exist for a long time.

The equation on the side was also very excited and nervous.

During this time, the X-ray laser base gave up other scientific research projects and concentrated on the development of room temperature superconductors.

The silver content of iron-silver alloys has been accurate to 3.746~3.747%, and the superconducting state at room temperature can be maintained for 864 hours (specially designed rapid detection method).

However, it can only maintain superconductivity at room temperature for 864 hours, which does not meet Huang Haojie's requirements.

After all, 864 hours can only last for 36 days, and this state of superconductivity at room temperature is not that if you don't use it, it won't decline; Whether it is used or not, when the time is up, its superconducting state at room temperature will decline.

Huang Haojie called this situation "deconduction", in fact, the deconduction of iron-silver superconductors at room temperature does not really lose superconductivity, but as if hidden.

The deconductioned iron-silver superconductor at room temperature is re-irradiated with X-ray laser, and the state of room temperature superconductivity can be restored.

The problem is, if you have already made a superconductor at room temperature into a finished product such as a circuit, you can't always rebuild it every 36 days, right? Obviously, this is not convenient and economical.

After all, Huang Haojie does not plan to sell superconductors at room temperature, and he can't pit himself for what he uses.

"Boss! Time's up! The equation reminded

"Let the robot take out the sample." Huang Haojie commanded.

"Robot group, take out the sample."

"Roger!"

After the four reactors are rotated to one position, the freshly baked iron-silver superconductor at room temperature is taken out by the industrial robot.

The transport robot transports four freshly formed superconductors at room temperature, passing through layers of isolation layers.

Came to a testing room.

The inspectors, who were already wearing heavy protective clothing, quickly put one of the pieces into the special testing equipment.

Doodle...... Another inspector, pressing rows of buttons.

Half an hour later.

The equation took a test report and ran over excitedly:

"Boss! Good news! ”

"How long has it been maintained?" Huang Haojie is still immersed in adjusting the experimental parameters.

"Sample No. 248 reached 2470 hours! More than 100 days! Equation said with excitement on his face.

Huang Haojie said expressionlessly: "It's not enough! It must have at least more than 30,000 hours of service life before it can be put into service. ”

Grunt! The equation is no surprise to Huang Haojie's pursuit of perfection, but the service life of 30,000 hours still makes him both nervous and full of fighting spirit.

Huang Haojie didn't care about the equation, and handed a parameter adjustment plan to the other party:

"According to my adjustment plan, four more samples will be concocted."

The equation that woke up like a dream hurriedly took it.

"Okay, I'll arrange it right away."

……

April 27th.

Experiments at the X-ray base are still proceeding in an orderly manner.

Huang Haojie has been here for more than a month.

However, with the assistance of "loyalty", Huang Haojie's control of Galaxy Technology is more like a finger, not only the workload is greatly reduced, but the quality and efficiency of work are several times that of before.

But at this time, Huang Haojie was in distress.

Because the superconductor at room temperature has entered a bottleneck period in the past few days, the service life has been stuck at about 14,000 hours.

He had already made it according to the method he remembered, but he didn't know what was wrong, and the service life of the superconductor at room temperature was stuck at 14,000 hours.

The equations on the side are also scratching their hair in distress, but the places they should have adjusted have been adjusted in the past few days, but they can't see where the problem is.

Could it be that the limit of iron-silver superconductors at room temperature is 14,000 hours?
