The Technology Tree of Xueba

When Zhou Yu walked into the superconducting laboratory, he recalled the content of superconducting technology in his mind.

The DC resistivity of a conductor suddenly disappears under certain conditions and is called the zero resistance effect. A conductor that reaches this state is called a superconducting state, and the moment when it does not enter the superconducting state is called the ground state.

The conductor has no resistance, and no heat loss occurs when the current flows through the superconductor.

There is no resistance in the conductor, so no voltage is generated. The superconducting current in the superconductor has zero voltage characteristics.

The current in the superconductor can form a strong current in the wire without resistance, thereby generating a super strong magnetic field.

When the conductor is in a superconducting state, the magnetic induction intensity in the superconductor is zero, which will squeeze out the magnetic field that originally existed in the body.

The judgment of a superconductor is confirmed by two phenomena: zero resistance effect and zero magnetic induction.

If these two phenomena occur in a certain conductor, it can be confirmed that it is a superconductor.

Zhou Yu continues to recall the principle of superconductor generation.

In a superconducting metal, electrons are attracted to each other by a lattice wave as a medium to form an electron pair.

Countless electron pairs overlap each other and often interchange objects with each other to form a whole. The flow of electron pairs as a whole produces a superconducting current.

Because it takes a certain amount of energy to disassemble an electron pair, there is an energy difference between the ground state and the superconducting state in the superconductor, that is, the energy gap.

Different materials have different energy gaps, and they have different conditions for forming superconductors.

It is now found that the only material that forms superconductors is metal, and people can only try to find high-temperature superconductors by making different alloys.

The practice of Ma Shangshu and Feng Yunde, however, is to find new types of materials that can produce superconducting phenomena and test its superconducting state to meet the conditions.

Zhou Yu walked into the superconducting laboratory and saw that the people here were busy. He did not interfere with the work of scientific researchers and went in the direction of the most people.

He found that these people were surrounding several blue-green plates, some of which had silver-white metal **** suspended above them, and some had silver-white metal **** inside.

The plate is covered with a glass cover, which shows the temperature inside the plate.

Zhou Yu immediately saw that the plate was made of superconducting material. The superconducting material entered the superconducting state, and the electromagnetic induction strength was zero, resulting in the phenomenon of repulsive magnetic lines.

The magnetic metal ball is directly repelled by a plate made of superconducting material, which is suspended above the plate.

The temperature of the plate is the temperature required for the superconducting state of this superconducting material.

Zhou Yu watched the temperature at which the metal ball suspended the plate.

As long as the temperature of the plate below 55 degrees Celsius, there are metal **** suspended above it.

When Zhou Yu saw this, he immediately understood that Ma Shangshu had successfully researched normal-temperature superconducting materials.

The minimum temperature upper limit of this normal-temperature superconducting material is so high that it reaches an alarming minus 55 degrees.

This is truly a normal-temperature superconducting material.

Ma Shangshu and Feng Yunde came over, and they immediately found Zhou Yu in the crowd.

Zhou Yu saw them coming with a smile, and said happily, "Congratulations on your successful development of normal temperature superconducting materials. The neutrino communication base station has encountered great trouble. Fortunately, your project has been successful and their problems have been solved."

Ma Shangshu said modestly: "I haven't done anything at all in the discovery of room temperature superconducting materials, but just tested the superconducting properties of this material."

Feng Yunde also said with a grin: "This material is just one of the silicon-based polymeric materials that I developed. If Ma Shangshu found it to have superconducting properties, it would probably be buried in our laboratory."

"Don't be modest for both of you, both of you have contributed a lot." Zhou Yu smiled.

"What are the physical characteristics of this superconducting material, can it be used to make wires? Its production process is not complicated, and what is the output?"

Zhou Yu asked with concern that this superconducting material can be used in industrial applications and it must meet the corresponding standards. The output of this superconducting material should not be too low and the manufacturing process should not be too cumbersome.

Feng Yunde took a plate from the booth and displayed it in his hand. He also introduced: "This superconducting material is a silicon-based polymer. I imitate the principle of organic material generation and replace the carbon chain with a silicon chain.

In the laboratory, I made the basic material of the silicon chain ‘silene’. Its structure is very similar to that of ethylene, except that carbon atoms are replaced with silicon atoms.

I use silicon as a material to make a lot of silicon-based polymeric materials.

This superconducting material replaces the hydrogen atom on the third silicon atom of butadiene with a divalent iron atom.

By using this silyl isobutyl iron as a raw material, a polymerization reaction is performed, and the polysilyl isobutyl iron produced is such a superconducting material.

I named this superconducting material green ferrosilicon.

Its reaction conditions are not difficult, and the equipment used for the polymerization of organic materials is also used, but the catalyst and the reaction conditions are different. "

"The research and development process of green ferrosilicon is quite complicated. This silicon-based organic material should be the focus of the material laboratory in the future.

The treasure trove of organic materials has not been dug up to now, and you have developed a new category of materials. You must not waste this opportunity. Zhou Yu said happily.

The material laboratory led by Feng Yunde, this is to develop a new type of material, and its potential is not lost to organic materials and nano materials.

"Zhou Zhou, every scientist at our Materials Research Institute can see the potential of silicon-based polymer materials." Feng Yunde said confidently.

Ma Shangshu interjected: "The topic has been crooked, let me introduce the physical properties of green silicon iron."

After the introduction of Ma Shangshu, Zhou Yu understood some characteristics of green ferrosilicon.

Green silicon iron has good toughness, but its hardness is not high, it is about the same as that of metallic silver.

However, ferrosilicon has good chemical properties and is very light in weight.

Green silicon iron is used as a conductor, and other organic materials can be mixed and braided into a cable for long-distance power transmission.

Zhou Yu learned that green silicon iron can be used to make cables. He instructed Feng Yunde: "You make a batch of green silicon iron and give it to the Neutrino Communication Lab, and let Zhao Zhao use green silicon iron to improve the neutrino communication base station. "

Feng Yunde waved his hand and said, "The production of such simple materials requires no equipment in our laboratory.

Besides, the output of the equipment in the laboratory is very low. It takes several months to produce 100 km of green ferrosilicon.

Its preparation process is really not difficult, UU reading www.uukanshu.com allows Xinghuo Material Company to make green ferrosilicon.

We have registered a patent for this material in China, and we are not afraid of leaking it. "

Feng Yunde said flatteringly after saying: "It is always Zhou's foresight to set up a science and technology research and development center in Xiong'an New District.

Many technology companies apply artificial intelligence Mozi, products are emerging endlessly, and the speed of patent application has been complaining.

Only those people who work slowly at the State Patent Office will change their work style and use artificial intelligence technology to increase patent approval time. "

"This is not my credit. This is the impact of social changes on government work." Zhou Yu said modestly.

After he understood the situation of green ferrosilicon, he immediately notified the general manager of Xinghuo Materials Co., Ltd. Gou Fugui and asked him to contact Feng Yunde, director of the Materials Research Institute.

Started large-scale production of green ferrosilicon, a superconducting material capable of manufacturing cables, not only for neutrino communication base stations, but also for Huaxia's backbone power grid.
