I! Pretending to Be Reborn, Director of Doomsday Hoax

Skyscraper wind farms, although very novel, are also very practical.

However, the biggest problem currently facing is the material.

As the main body of power generation, the feather structure covering the entire skyscraper is the top priority.

Mo Hongxi and others have screened out eight materials that meet the requirements of the skyscraper "feather".

Of course, the Special Materials Research and Development Department has been synthesizing new materials to obtain more superior products.

just before today,

The team led by Professor Chen Yongsheng successfully developed a superconducting material!

A superconducting material refers to a material that exhibits the properties of zero resistance and repelling magnetic lines of force under certain low temperature conditions.

It has some incomparable advantages.

For example, zero resistance.

In the superconducting state, superconducting materials have zero electrical resistance and can transmit electrical energy without loss.

If a magnetic field is used to induce a current in the superconducting loop, this current can be maintained without decay.

This "persistent current" has been observed in experiments many times and is real.

In theory, as long as the manufacturing level reaches a certain level, it can be used in reality.

At present, there are 28 elements with superconductivity under normal pressure.

Among them, armor is the most superior element.

In the electrical field, ingots and lead have been used to manufacture superconducting AC power cables, high-Q resonant cavities, etc.

Lu Guangyuan introduced the situation.

Prior to this, Longguo's Special Materials Research and Development Department was conducting several studies at the same time.

Every research result may change the ecology of the superconductor industry, and even become a superconducting material with great development prospects.

Or could be the well-deserved "feather" of a skyscraper wind farm.

The first is the flux dynamics and superconducting mechanism of unconventional superconductors.

This laboratory mainly studies the mechanism of magnetic flux line movement in the mixed state region, the properties and causes of irreversible lines and their relationship with magnetic field and temperature, and the dependence and anisotropy of critical current density with magnetic field and temperature.

The research on the superconducting mechanism focuses on the magnetoresistance, Hall effect, fluctuation effect, Fermi surface properties of the normal state under a strong magnetic field, and the transport properties when the superconducting state is destroyed by a strong magnetic field at TTc and reaches the normal state.For systems that are expected to exhibit high-temperature superconductivity, such as organic superconductors, and low-temperature superconductors that have broad application prospects in strong electricity, the special materials team focuses on their properties under strong magnetic fields.

The second is the study of the characteristics of low-dimensional condensed matter under strong magnetic field.

In addition, the optical and electrical properties of semiconductor materials under strong magnetic fields,

Physical problems in extremely fine scales under strong magnetic fields...

And the most important thing is strong magnetic field chemistry!

The effect of a strong magnetic field on the chemical reaction electron spin and nuclear spin can lead to the relaxation of the corresponding chemical bonds, create favorable conditions for the formation of new bonds, induce physical and chemical changes that cannot be realized under normal conditions, and obtain new materials and new materials that cannot be prepared before. compound.

Strong magnetic field chemistry is a new field with strong application foundation, and has a series of theoretical topics and broad application prospects.

Professor Chen Yongsheng is in charge of this research topic.

From solid-state physics to condensed matter physics, from periodic structures to non-periodic structures, from three-dimensional crystals to low-dimensional and high-dimensional, and even fractal systems...

Professor Chen Yongsheng's team has been exploring for more than a month.

Compared with other extreme conditions, strong magnetic fields have their own characteristics.

The function of a strong magnetic field is to change the physical state of a system, that is, to change the angular momentum spin and the orbital motion of charged particles,

Therefore, the state of the physical system is changed.

It is in this respect that strong magnetic fields differ from some of the more expensive means of physics, such as neutron sources and synchrotrons,

They do not change the physical state of the system under study!

Magnetic fields can create new physical environments and lead to new properties that would not exist without the magnetic field.

Although low temperatures can also lead to new physical states, such as superconductivity and phase transitions,

But a strong magnetic field is very different from low temperature, it is more effective than low temperature!

Because, the magnetic field quantizes the telemotion and energy of charged and magnetic particles and breaks the time-reversal symmetry, giving them more unique properties.

This is the most important mechanism by which strong magnetic fields can create new materials! !

In addition,

A strong magnetic field can change the symmetry of the momentum space while keeping the crystal structure unchanged!

This is very important for the study of the energy band structure of solids, elemental excitations and their interactions.

For example, the complex Fermi surface structure of a solid uses a strong magnetic field to ensure the free movement of electrons and holes in a specific direction, resulting in the oscillation of magnetization and reluctance!

Professor Chen Yongsheng's superconducting material is based on the Fermi surface structure.

The study of the structure and characteristics of the Fermi surface in solids has always been a frontier topic in the field of condensed matter physics.

Many major hotspots in the basic research of condensed matter physics today are inseparable from the extreme conditions of strong magnetic fields, and many are even based on research under strong magnetic fields.

If Bose condensation only occurs in momentum space, it must be possible in a non-uniform strong magnetic field to observe this phenomenon in real space.

Another example,

Mechanism of high-temperature superconductivity, research on quantum Hall effect, physical problems in nanomaterials and mesoscopic objects, physical causes of giant magnetoresistance effect, structure and origin of organic ferromagnetism, mechanism and magnetism of organic superconductors, low-dimensional magnetism Phase transition and magnetic interaction of materials, energy band structure and Fermi surface characteristics in solids, research on elemental excitations and their interactions, and more!

Chen Yongsheng's team, in addition to being the top superconducting material expert in Longguo himself, also included several top physicists, mathematicians, and many talents in the fields of nanotechnology and polymer chemistry. Guide material launched!

"This material perfectly meets the requirements of skyscraper wind farms, and can be used as the feathers of skyscraper wind farms!" Lu Guangyuan said excitedly.

"Has Mo Hongxi already started using it?"

"At present, this material is still in mass production. Engineer Mo intends to report to you after testing the practicality."

Xu Qiu nodded.

Ultra-low temperature superconducting materials are indeed an excellent choice for skyscraper wind farm feathers.

Next, it depends on whether Mo Hongxi will let himself down.

"Before the Little Ice Age, a complete and preliminary prototype of a skyscraper wind farm could not be obtained. The main engineer of the Wind Dragon Project will be replaced."

Xu Qiu's voice is very flat, but it can dominate anyone's power and status!

Feeling the coercion emanating from Xu Qiu, Lu Guangyuan and the others respectfully said: "Obey, I must complete the task!"

Xu Qiu nodded and asked everyone to retreat, leaving only Li Bingqing in the office.

He leaned back on the chair, let Li Bingqing pinch his shoulders, and looked at the world map on the wall directly opposite, with a smile on his lips.The Little Ice Age is coming,

Next, it's time to start laying out bigger frauds.

How could Xu Qiu be satisfied with just manipulating the doomsday construction of a Dragon Kingdom?

Next, he will become the chief engineer of all mankind! !

Three days later.

Longguo Fenglong Project Headquarters, Special Materials Research and Development Department, High Magnetic Field Superconducting Materials Research Laboratory.

The white-haired Chen Yongsheng, with dark circles under his eyes, walked out of a laboratory full of equipment priced at more than [-] million yuan.

"The result came out, the critical parameter problem has been solved!"

He looked tired and excited!

The superconductor materials studied before have a big weakness.

Too much brittleness!

Therefore, in the past few days, Chen Yongsheng led the team and has been overcoming the problem of the material manufacturing process, making the highly brittle superconductor material into a soft and thin wire!

If you want to bear the "feather", it must be soft enough.

Now, this problem has been solved.

Mo Hongxi, who was rooted in the research and development department of the skyscraper wind farm, heard the news and ran over excitedly.

"Senior Chen, have you finished?" Mo Hongxi's hair was like a chicken coop, and he had no image at all.

Chen Yongsheng nodded excitedly.

"Is the Josephson effect also incorporated?" Mo Hongxi asked.

The Josephson effect is a supercurrent phenomenon across the Josephson junction.

The Severson junction is composed of two superconductors that are weakly connected to each other, and the structure of this weak connection can be a thin insulating layer, called a superconductor-insulator-superconductor junction, or S4S for short.

This is a manifestation of the macroscopic quantum effect. Prior to this, it was only known that electrons in a non-superconducting state can flow through the insulating layer through the quantum tunneling effect.

The emergence of the Josephson effect has broken this common sense!

In short,

If the Josephson effect is used to make a series of precision measuring instruments, radiation detectors, microwave generators, logic elements, etc.,

Using Josephson junction as the logic and storage elements of the computer, its operation speed is ten to twenty times faster than that of high-performance integrated circuits, but the power consumption is only one-fourth!

If, superconductor materials with Josephson effect can be used in skyscraper wind farms!

It will become a fully intelligent, fully automatic wind farm that does not require human manipulation.

And because the calculation speed is too fast and the power consumption is too low,

The energy conversion efficiency of skyscraper wind farms will be improved again!

The most attractive place for superconducting materials is actually here--

Power Generation, Transmission and Storage!

Using superconductor materials to make the coil magnets of superconducting generators can increase the magnetic field strength of the generators to 50.00 to [-] Gauss, and there is almost no energy loss.Compared with conventional generators, the stand-alone capacity of superconducting generators is increased by dozens of times, and the power generation efficiency is increased by more than [-]%!

Moreover, superconducting transmission lines and superconducting transformers can deliver electricity to consumers with almost no losses.

Estimated based on the best power transmission capacity in the world, about 15.00% of the power loss is on the power transmission line through copper or aluminum wires, and the annual power loss in Longguo is more than 1000 billion kWh.

If it is changed to superconducting power transmission, the energy saved is equivalent to building dozens of large power plants!

Moreover, this material, with technological improvements, can even be used in superconducting computers!
