Great Country Academician

"Is there any well-preserved experimental data? Let me take a look."

In the laboratory, Xu Chuan asked Fan Pengyue for the experimental data, and glanced at the familiar equipment by the way, with a hint of embarrassment in his eyes.

This is probably the place where he spent the longest time except for the library since his sophomore year in his last life.

Starting from the simplest and most basic tray balances, scales, measuring cylinders, and thermometers, to intermediate equipment such as vacuum pumps and infrared spectrometers, to top-level deep ultraviolet lasers, high-resolution mass spectrometers and other large analytical instruments.

Oh, and the familiar white coat.

These things have helped him develop one material after another.

The physics laboratory of Nantah University is quite well-equipped. After all, Nantah University’s School of Physics ranks among the top three universities in the country. In terms of physics, the annual research funding is still quite sufficient.

"Yes, I just finished an experiment this morning, and the data is still there."

Fan Pengyue nodded, turned around and took a document from the silver-white metal table in the laboratory and handed it to him.

Xu Chuan took it and flipped through it. Sure enough, there was something wrong with the experimental data.

It was subtle, but it couldn't escape his eyes.

After all, he has seen a lot of experimental data of low-dimensional materials, and the relevant energy spectrum can be found in the first time in his mind.

This is the accumulation of experiments.

On the side, Fan Pengyue leaned over and began to explain to him the experimental data corresponding to this material.

"This data on the preparation of tungsten diselenide nanosheets comes from the one-step synthesis of solvothermal method. The highly crystalline tungsten diselenide nanosheets prepared by this method have large scale, fewer layers, uniform distribution, and high specific surface area."

"But correspondingly, the larger the surface area, the greater the chance of collapse and superposition of the finished product."

"If you look at these two sets of data, the previous one is a tungsten diselenide nanosheet with a diameter of three microns, and the yield rate can still be maintained at more than 90%, but when the diameter of the tungsten diselenide nanosheet is expanded to ten After the micron squared, the yield rate dropped sharply, and the final stability rate was less than 60%.”

After glancing at the picture group pointed by Fan Pengyue, Xu Chuan shook his head and said, "Not only."

"Analysed from the data, the yield of your second group can't reach 60% at all. Look at this image, when it tiles the energy spectrum crystal structure, there is a prominent small peak section. This also represents a loss of material."

"But you have overlooked this point. It is in the early stage of occurrence. Although it looks very inconspicuous, its actual proportion is larger when it is enlarged. According to my calculations, when the diameter of tungsten diselenide nanosheets increases After reaching more than ten microns square, your yield rate can’t even reach 50%.”

After thinking for a while, Xu Chuan calculated in his mind, and then said: "To be precise, it should be around 48.3%. Of course, this is just the data I calculated in my head, so it can't be more accurate, more accurate If so, I need to use pen and paper to calculate."

On the side, after listening to Xu Chuan's analysis, Fan Pengyue looked at Xu Chuan dumbfounded. After hearing the last number, he quickly found a pen and paper from the laboratory to check the calculation.

After more than ten long minutes passed, Fan Pengyue couldn't help swallowing while looking at the calculated data on the manuscript paper.

It took him more than ten minutes to calculate the data, which was exactly the same as what Xu Chuan said just now.

Of course, the numerical value should be more precise, the percentage is 48.32.

"Little brother, are you still a human being?"

"You are not a quantum computer robot in disguise, are you? Do you have a quantum brain?"

After staring at the data on the manuscript paper for a long time, Fan Pengyue got up and looked around Xu Chuan in surprise, as if looking for evidence that he was a quantum robot.

He was shocked, really shocked.

I knew before that this little junior was very perverted, but I didn't expect to be so perverted.

With just one glance, they can see through the loopholes in their calculation of the experimental data, and can even calculate the precise answer containing the loopholes in a few seconds by mental arithmetic.

And for these few seconds, he, a doctoral student, counted for a full ten minutes, although there are also reasons why he is not a mathematics major and not proficient in functional analysis.

But he is also a doctoral student of 985 anyway, and he specially studied functional analysis for a period of time before, but he was hanged and beaten.

Is this the true ability of the little junior brother?

Xu Chuan couldn't help touching his nose after being complained about by the elder brother.

Although it is said that he can enter the data and calculate it so quickly with the help of memory knowledge brought by rebirth, but in the past few months when he was studying mathematics, he felt that he was a bit abnormal.

Many knowledge points can be memorized after reading it once, and some unsolvable problems can be solved by asking a tutor to solve it.

Memory, mental arithmetic ability, and mathematical logic all seem to be much stronger than in the previous life.

He himself didn't understand the specific reason for this, but he guessed that it was most likely due to the factors that the body and brain were at the youngest and peak after rebirth.

After all, once a person becomes an adult and reaches about 20 years old, the brain will age, and brain cells will gradually decrease with age.

After the age of 20, people start to grow old.

And he is not yet eighteen years old, and he is at his peak.

Coupled with the scientific knowledge and insights from previous lives, it doesn't seem strange.

"Mentor, come quickly, the junior brother has found a problem here."

Suddenly, Fan Pengyue seemed to remember something, and called out to Chen Zhengping on the other side.

"Wait a minute, this side will be over soon."

Chen Zhengping responded quickly, but continued his experiment without haste.

Those who engage in applied physics must be calm, and they must turn their hands on the experiment to the point where earthquakes are nothing.

After all, every experiment is money, a budget, and scientific research funds.

If the scientific research funds are spent but the results are not produced, it will be a scam.

So even if you know that the experiment has a high probability of failure, you must complete it seriously, standardize each operation step and record complete data.

Experiments can fail, which is no problem, but the failure process and data must be fully recorded, analyzed and adjusted to ensure that such problems will not occur again in the next experiment.

This is the true meaning of applied science.
