Chapter 92 Are you afraid you have a quantum brain? (Third update, please seek monthly tickets for Zhuidu)
"Is there any well-preserved experimental data? Let me take a look."
In the laboratory, Xu Chuan asked Fan Pengyue for some experimental data, and glanced at the familiar instruments and equipment, with a hint of sadness in his eyes.
This is probably the place where he spent the longest time in his last life, except the library, after his sophomore year.
Starting from the simplest and most basic things such as pallet balances, scales, measuring cylinders, and thermometers, to mid-level equipment such as vacuum pumps and infrared spectrometers, to top-notch deep ultraviolet lasers, high-resolution mass spectrometers and other large analytical instruments.
Oh, and there’s the familiar white coat.
These things have helped him develop the same materials.
The equipment in NTU's physics laboratory is quite complete. After all, NTU's Institute of Physics ranks among the top three among universities in the country. In the field of physics, the annual scientific research funding is quite sufficient.
"Yes, I just completed an experiment this morning and the data is still there."
Fan Pengyue nodded, turned around, took a piece of information from the silver-white metal table in the laboratory and handed it to him.
Xu Chuan took it and turned it over. Sure enough, there was something wrong with the experimental data.
It's very subtle, but it can't escape his eyes.
After all, he has read countless experimental data on low-dimensional materials. The relevant energy spectrum diagrams can be found in his mind as soon as they come to mind.
This is the accumulation of experiments.
On the side, Fan Peng came closer and began to explain to him the experimental data corresponding to this information.
"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, few 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."
"Look at these two sets of data. The first one is a tungsten diselenide nanosheet with a diameter of three microns. The yield can still be maintained at more than 90%. But when the diameter of the tungsten diselenide nanosheet is expanded to 10 After micron square, the yield dropped rapidly, and the final stability rate was less than 60%.”
After looking at the group of pictures pointed out by Fan Pengyue, Xu Chuan shook his head and said, "No more."
"From the data analysis, the yield of your second group cannot reach 60% at all. If you look at this image, when it tiles the energy spectrum crystal structure, there is a prominent small peak segment. This also represents a loss of material.”
"But people have ignored this. It is in the early stage of occurrence. Although it looks very inconspicuous, the actual proportion is larger when enlarged. According to my calculations, when the diameter of tungsten diselenide nanosheets expands, After reaching more than ten microns square, your yield will not even reach 50%.”
After thinking about it, Xu Chuan calculated it in his mind, and then said: "To be precise, it should be around 48.3%. Of course, this is just my mental calculation data. It cannot be more accurate. If so, I need to calculate it with pen and paper.”
On the side, after listening to Xu Chuan's analysis, Fan Pengyue stared at Xu Chuan in shock. After hearing the last number, he quickly found paper and pen from the laboratory and started to check it.
More than ten long minutes passed, and Fan Pengyue couldn't help but swallow as he looked at the calculated data on the manuscript paper.
The data he spent more than ten minutes calculating were exactly the same as what Xu Chuan just said.
Of course, the numerical value must be more precise, the percentage is 48.32.
"Junior 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 stood 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 brother was very perverted, but I didn't expect him to be so perverted.
With just one glance, he could see through the loopholes in their calculations of experimental data, and he could calculate precise answers containing the loopholes in just a few seconds using mental arithmetic.
In these few seconds, he, a doctoral student, calculated for a full ten minutes, although there was also a reason why he was not a mathematics major and was not proficient in functional analysis.
But after all, he was also a doctoral student in 985. He had studied functional analysis for a period of time before, but he was hung up and beaten.
Is this my junior brother's true ability?
After being complained about by his senior brother, Xu Chuan couldn't help but touch his nose.
Although he was able to input data and calculate so quickly with the help of the memory knowledge brought by his rebirth, he himself felt a little abnormal when he was studying mathematics in the past few months.
Many knowledge points can be roughly memorized by reading it once. Some unsolvable problems can be solved by asking a tutor to solve them just by listening to them once.
My memory, mental arithmetic ability, and mathematical logic all seem to be much stronger than in my previous life.
He himself didn't understand the specific reason for this, but he guessed that it was most likely caused by the fact that his body and brain were at their youngest and peak after rebirth.
After all, once a person reaches adulthood, around the age of 20, the brain will begin to age, and brain cells will gradually decrease with age.
After the age of 20, people start to age.
And he is not yet eighteen years old, which is when he is at his peak.
Coupled with the scientific research knowledge and insights from previous lives, it doesn't seem strange.
"Teacher, come quickly, junior brother has found a problem here."
Suddenly, Fan Pengyue seemed to remember something and shouted to Chen Zhengping on the other side.
"Wait a moment, it will be over soon."
Chen Zhengping responded quickly, but continued his experiment unhurriedly.
Those who engage in applied physics must be able to keep their composure and start the experiments in their hands so that earthquakes are as if they are nothing.
After all, every experiment is money, a budget, and scientific research funds.
It would be a lie if the scientific research funds are spent but the results are not produced.
Therefore, even if you know that there is a high probability that the experiment will fail, you must complete it seriously, standardize each operation step, and record complete data.
Experiments can fail, and that’s okay, but the failed process and data must be completely 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.
