The resistivity measurement of elemental metals is a small experiment that can be performed in conventional physics laboratories, but it is different for first-order gold with extremely low resistivity.
Pure gold has a very low resistivity and is just a regular wire.
The resistivity of first-order gold is five orders of magnitude lower. To measure it, the material must be cut into fine pieces, and very precise instruments are required to measure it.
This requires a professional team to design experiments.
If you want more accurate values, you need to design several experiments to record the data and then average it.
Now it has been determined that the resistivity of first-order gold is on the order of ‘10^(-13)’, which is definitely something worth getting excited about.
When Teacher Zhao came to find Wang Hao, he heard the news immediately, and then asked with some confusion, "What does the resistivity mean when the resistivity is five orders of magnitude lower?"
He knew that Wang Hao had told him to measure the resistivity of first-order gold, but he didn't know what he meant specifically. He just thought it was an ordinary property measurement.
Zhou Qing next to him couldn't help but said, "What does it mean? Do you even need to ask? It's almost superconducting!"
"..."
Wang Hao glanced at Zhou Qing and suddenly understood him better.
This guy has absolutely no emotional intelligence.
Isn’t it normal for decision-making leaders not to understand technical issues? People who are not experts in the field may also be confused when they hear it, and the answer is, ‘Do you even need to ask?’.
Teacher Zhao felt a little embarrassed. Anyway, he had a good temper and didn't care about anything. He continued to ask, "Close to superconducting? Does this mean that this can become a material that can replace room temperature superconducting?"
"right!"
Zhou Qing answered and gave a teachable look.
Teacher Zhao was very happy, and even got excited when he thought about it carefully, "Replacing normal temperature superconducting means superconducting. Can it be used in ordinary electronic products?"
"sure."
Wang Hao felt that Zhou Qing could not be allowed to speak more, so he hurriedly said, "Many electronic products have gold coatings on the metals used inside them. A few of them are used as conductors, but they are usually used as coatings because the properties of the gold element are relatively
Stablize."
"However, the reason gold is rarely used as a conductor is because its resistivity is higher than silver and copper, especially copper, which is very low cost."
"The current first-order gold is close to room-temperature superconducting materials, so it can naturally be used as an important component conductor in some electronic devices, but..."
“The cost is too high!”
Teacher Zhao finally figured it out.
The resistivity of first-order gold is indeed low enough, close to that of superconducting materials, but the problem is that gold is a precious metal, and first-order gold will definitely be more expensive.
If first-level gold is officially sold in the future, it will be very easy to increase the initial price several times, and it will be easy to sell thousands of flower coins per gram.
Therefore, it is difficult for ordinary electronic products to use first-order gold.
Only some high-end products may add a very small amount of first-order gold to the most critical components, and even if only one gram of first-order gold is added, the cost may increase significantly.
Of course, there are also some areas where the price of first-order gold does not need to be considered.
For example, in the aerospace field.
In the aerospace field, many materials are much more expensive than gold.
If first-order gold is used as a conductor material, the efficiency of solar power generation and electric energy use can be greatly improved, and the high price of first-order gold will be nothing.
After an exciting discussion, Teacher Zhao couldn't help but sigh, "What a great discovery! I believe this will change the world. At least first-order gold will definitely be used in the aviation field in the future. The technology in this field will see huge development...
"
"yes!"
“You can look forward to it.”
"But I'm looking forward to the first-level silver..."
Wang Hao finally added, "I hope this technological improvement can produce first-order silver. First-order silver has the same characteristics as first-order gold, and the resistivity will be lower."
"The cost will also be dozens or hundreds of times lower."
Zhou Qing nodded vigorously.
Teacher Zhao also started to look forward to it, and said with some regret, "I'm leaving today. I really want to stay here and watch your research."
"It's really amazing!"
"This base is the driving force for our country's technological take-off and the starting point for earth-shaking changes in human science and technology."
"Academician Wang, Professor Zhou, and all other researchers..."
"Thank you for your hard work!"
…
Groom Lake Experimental Site, Lincoln County, Nevada.
Under the leadership of Empoli Kubo and Corot James, they chose to complete a new experiment. They changed the direction of the peripheral magnetic field. As a result, the measured annihilation force field strength was still weakened.
That is to say...
"The experiment failed again!"
Clotte-James let out a long sigh and said to the other people in the conference room, "I felt that it was not possible at the beginning of the experiment. We had no theoretical basis at all. We just thought of a way to make changes and then conducted the experiment.
"
"If you want to increase the strength of the force field, the most direct way is to increase the strength of the anti-gravity field."
"There has been a lot of research in this area, and there is a limit to the antigravity field created by high-pressure hybrid materials near the transition temperature."
"We don't know what the specific limit is. But there is so much data in the experiment, so we can make a guess...probably, 40!"
"40 percent is almost the limit."
"With this force field strength, the strong annihilation force field created by the superposition of field forces will not exceed seven times at most. With the built-in heat source and magnetic field extrusion, it will only exceed eight times at most..."
"So what we can be sure of is that Wang Hao's team must have used other technologies, unlike us."
Kollot James' words made everyone else nod.
They believed that Wang Hao's team used other technologies, otherwise it would not have been possible to create an annihilation force field that was more than ten times stronger. They still had some guesses about Wang Hao's team's technology.
A researcher named Bob summarized a few points, "First of all, what they created is an area, not a thin layer."
"This is inevitable. They used strong annihilation force fields to produce large amounts of magnetized materials, and our research proves that 'thin layers' will not work."
"In addition, there is no heavy external magnetic field, and magnetic interference technology may not even be used. This can be guessed from the efficiency of annihilation technology in producing magnetized lithium and first-order iron."
"Of course, this is not certain."
"Finally, the field force they create may not have a built-in heat source. The reason is the same as the first point. They are creating an area."
After Bob summarized the three points, Brewster immediately retorted, "Bob, I agree with the first point you made, but the second and third points are not necessarily true."
"We can also create an area with a strong annihilation field. We only need to use magnetic interference to empty one side to create a cylindrical area."
The others nodded after listening.
Brewster continued, "Also, you said there is no built-in heat source? How do you explain the nuclear fusion project? Their central device is always running!"
Bob was refuted and had nothing to say.
No matter how rigorous his analysis is, he still has to face the issue of nuclear fusion.
The deuterium-deuterium fusion reaction built into that device has been detected by satellites in the sky as high heat, which naturally means that there must be a built-in heat source.
Next, the two groups began to argue with each other.
Bob is also a famous physicist and has a high prestige within the project team. The same goes for Brewster. The supporters of the two started a debate. When they had nothing to say, they almost started fighting.
.
Korot James watched it with relish.
He also said to Cooper, "Do you think they can fight? I think that sturdy black doctoral student is very good. He is Bob's student? If this guy takes action, I bet Brewster will kneel down immediately and admit his guilt."
Coward..."
Cooper glared at him helplessly, "That's Wilson, a guy who's easy to get along with. Even if you are racist... don't show it."
Seeing that the conference room was too messy, he quickly slammed the table a few times and said, "Quiet! Quiet! Please stop making noises!"
