I just want to be a quiet scholar

Chapter 435 Believe in Science
The FASTER project can be said to be progressing smoothly. The first research and development results have been successful, the patent development rights have been sold, and it has also created a certain volume in international journals such as "Physics Today", "Nature", and "Chemical Review".

The experimental products of the B series are under intense and orderly research and development. This series is based on the cerium-gallium-copper amorphous alloy. Shen Qi hopes to develop experimental products with better micro-nano processing performance.

It is not difficult to simulate the cerium-gallium-copper amorphous system by computer, but in real experiments, there are some problems in preparing an ideal cerium-gallium-copper alloy.

In the preparation of the A series of samples, Shen Qi and his colleagues obtained data and experience that the higher the purity of cerium, the better.

For the samples of series B, gallium replaced the aluminum in the samples of series A.

At this time, the problem came out. For the preparation of cerium-gallium-copper alloy, the higher the purity of cerium, the worse the performance of the obtained alloy sample.

Shen Qi, who was sitting in the office, looked at the data report. He couldn't sit still, so he went to the laboratory of the Institute of Physics and Technology to learn about the experimental situation on the spot.

Since he had the plan to have a BB, the number of times Shen Qi came to the laboratory decreased, and he made long-term plans in the office, read philosophy and history books, and practiced calligraphy.

Shen Qi came to the laboratory, put on protective equipment, and went to battle in person to find the root of the problem.

Shen Qi selected ten industrial-purity Ce ingots (nominal purity 99.7wt.%) and one high-purity Ce ingot (nominal purity 99.9wt.%), and tested the properties of Ce metal by XRF (X-ray fluorescence spectroscopy) method. Purity, and the content of impurity elements measured by inductively coupled high-frequency plasma spectrometer.

Everyone looked at the data around the computer. It can be seen from the data that the critical formation size of the cerium-gallium-copper amorphous alloy varies from 1mm to 20mm depending on the purity of Ce.

"There is indeed a problem. The lower the purity of the cerium element in the raw material cerium ingot, the better the amorphous formation ability of the prepared cerium-gallium-copper amorphous alloy? In our experimental design during this period, what link went wrong? ?" Tang Yuan frowned, looking depressed.

"I don't agree with Brother Tang Yuan's point of view." Shen Jinbao said.

Tang Yuan gave Shen Jinbao a blank look: "You can shut up now."

Shen Jinbao did not shut up, but gave her explanation: "Because gallium replaces aluminum, the intrinsic local structure characteristic in the B-series amorphous system, that is, the free volume must change. Our experimental design and There is no mistake, we can draw a qualitative conclusion through the real data, the raw material cerium ingots of the B series samples, we must use low-purity cerium ingots, because low-purity cerium ingots are the most suitable in this specific series.”

Tang Yuan was a little surprised: "Yo, what you said seems to make sense."

Shen Jinbao must be a little real, otherwise she would not be admitted to the postgraduate entrance examination, and she would not be able to go to the doctoral stage.

Tang Yuan asked Shen Jinbao: "But the question is, what kind of change happened to the free volume in the B-series amorphous system?"

Shen Jinbao looked at Shen Qi: "Perhaps Academician Shen can answer this question."

"Yes, Jinbao has made progress." Shen Qi praised Shen Jinbao, and then answered: "The data show that the Doppler broadening spectrum of all cerium-gallium-copper metal plastics from gallium 6 to gallium 13 is the same as that of cerium alone. , which indicates that the chemical environments around the annihilation sites of τ1 and τ2 are both cerium atoms."

"I noticed that τ1~130ps is less than the defect-free intrinsic annihilation time of face-centered cubic cerium, which is 197ps. So I speculate that low-purity cerium is more conducive to the synthesis of cerium-gallium-copper metal plastics with excellent performance. On the contrary, the purity of gallium must be It must be high. If the follow-up experiments prove my guess, it means that my theory of defect topology research is not wrong." Shen Qi became more and more energetic as he spoke, so he operated a DSC again, through differential scanning calorimetry method to obtain a set of data.

DSC data show that the thermodynamic properties of the B series amorphous alloy samples prepared from different purity Ce raw materials are also different.

"understood."

"Academician Shen's explanation is reasonable."

The researchers actively discussed that collective power can overcome all difficulties, and the problems are solved one by one under the teamwork of this kind of teamwork.

Shen Qi cleared the fog, and everyone reached a consensus that the following experiments should focus on low-purity cerium and high-purity gallium.

How low the purity of the raw material cerium is, of course, cannot be as low as less than 95%.

How high purity gallium is suitable, is it 99.99999%?
99.99999% gallium does not exist. Extracting extremely high-purity gallium at low cost is another topic in the industry.

The purity of cerium? ? , the purity of gallium? ?

To solve the question mark, the project team needs to continue research and practice, and get the answer through a large amount of experimental data.

The large amount of high-purity cerium ingots used in previous experiments was useless, and the equipment energy for preparing and testing samples was wasted.

This is the case with experimental physics, which is a money-burning business.

The consumption of raw materials and energy cannot be said to be a waste, at least Shen Qi and the others discovered an unworkable wrong route in advance.

Once the experiment is done, it is sometimes addictive.

Shen Qi has become more diligent when going to the laboratory recently, but he keeps in mind his promise to his wife, no matter how busy he is at work, he must be home before ten o'clock in the evening.

Spring goes to summer, and enters early summer.

It is not too far away from the day when the Nobel Prize will be drawn in October.

Shen Qi's career is very smooth. Even if he encounters some technical problems, he and his team can solve them in time.

Some domestic and foreign media began to focus on Shen Qi, speculating whether Shen Qi could win the Nobel Prize this year and what kind of Nobel Prize he won.

It seemed to be going smoothly, but Shen Qi felt uneasy.

He is not worried about his career, but his wife's health.

Shen Qi and Ouye have been married for more than half a year, and have been artificially created through scientific methods for more than half a year.

Ouye is still not pregnant.

There must be a problem.

Tonight, Shen Qi solemnly said to Ouye: "Honey, we will go to the hospital for an examination recently, and both of us will do it."

"Odd, it's all my fault, I can't even conceive a child..." Ouye choked up and sobbed.

Shen Qi held Ouye's hand and encouraged softly: "Honey, we have to believe in science. We'll go to the hospital when you're ready."

Ouye wiped away tears, ready to bravely face all possibilities: "Yeah."

Pre-pregnancy examination does not mean that you can do it temporarily if you want to do it.

The doctor's suggestion is that the woman's pre-pregnancy check-up should be carried out within 3 to 7 days after her menstrual holiday, and it is best not to have intercourse before the check-up.

The doctor also suggested that both husband and wife should carry out pre-pregnancy examination at the same time, preferably 3 to 6 months in advance.

Three to six months ago, Shen Qi and Ouye did not go to the hospital.

But now, Shen Qi had to pay attention to it and be prepared to face the reality.

In fact, the current medical methods are very advanced. Even if the couple cannot conceive through normal intercourse, there are many other effective scientific solutions.

So Shen Qi encouraged Ouye to believe in science.
