The spatial grid in which atoms are arranged regularly in a crystal is called a lattice. The lattice is composed of many minimum geometric units of the same shape and size stacked repeatedly. The minimum geometric unit that can fully reflect the lattice characteristics is called a unit cell.
From molecular structure to each atomic unit cell, lattice...
Unit cell < lattice < grain < crystal, from micro to macro, Wu Tong compares and proves them one by one.
·····
Calming down and delving into it, Wu Tong was fascinated by the beauty of this microscopic world. In the past, the materials she knew were basically macroscopic existences. This was the first time that Wu Tong entered this microscopic world, and the world was expanded again.
Once again, Wu Tong felt a little ashamed of her previous shallow foundation. She knew the results but not the reasons. She made two kinds of materials with her mathematical skills and special deductions, and was praised by others. She was really overrated. Sure enough, she still had a lot to learn!
Ions, molecules, subatomic particles, microscopic morphology, phase composition, phase transition, microregion, phase interface, surface chemical composition distribution, crystal segregation... Spatial distribution of elements in materials... Chemical environment and bonding environment around ions...
Some of the detailed knowledge of the materials involved were things Wu Tong had a rough understanding of, and some were things he had not yet learned. He deduced on the one hand and looked for information in books according to his needs on the other, quickly absorbing the essence of the knowledge. Wu Tong's material knowledge tree was rapidly filled up and gradually flourished to the smallest details.
Time had become almost intangible to Wu Tong. His entire mind was devoted to studying, experimenting, and deducing. More studying, experimenting, and more deduction, repeating the cycle. Aside from his morning exercises and the occasional calls home, Wu Tong had virtually no contact with the outside world, completely absorbed in his work.
She was always in the library, laboratory, dormitory and cafeteria. Occasionally, she would stay in the laboratory too late and take a nap in the office set up for her by Professor Cheng in the laboratory to restore her energy. This was a common occurrence.
Knowing Wu Tong's exceptional learning speed, the school had already granted her unlimited access to the library. Wu Tong simply found her suitcase, hauled back as many books as she could, and then meticulously studied them. After thoroughly studying one box, she'd move on to another, perhaps every three to five days, or at most a week. This was probably faster than the average student's ability to finish just two or three books.
Wu Tong's learning attitude directly stunned all the big and small people in the laboratory. Everyone began to spontaneously, as if they were wound up, to increase their learning intensity, treat every experiment more seriously, and dare not slack off.
Wu Tong, who is much more talented than them, has already led major national projects and has two super materials in his hands, but he is still studying so hard and immersed in it. What qualifications do ordinary people like them have to be lazy and rest?
In this state, Cheng Lao himself felt that he should reflect on himself and ask if he had not put enough effort into learning mathematics. He was not yet completely old, so he still had to pick it up.
The entire laboratory began to roll back from top to bottom.
This urgency swept through the School of Materials Science and Engineering. Many students in the School of Materials Science and Engineering saw that these seniors or classmates, who in their eyes had already become successful bigwigs by joining Mr. Cheng's laboratory, were still so obsessed with reading that they spent almost all their time studying except for eating. They couldn't help but tease them, asking whether they should leave a way out for these poor students?
This group of people couldn't help but smile bitterly. They also wanted to do that, but who could blame the top genius boss Wushen for not leaving them a way out to relax?
They are more talented than them and work harder than them, so they deserve to be outstanding.
The big guys will only get better and better, and go higher and higher. If they don't work harder, they will not be able to keep up with the big guys. Even if the big guys don't tell them, they don't have the ability to stay in the laboratory.
The winners advance and the losers retreat. Competition in this world exists at all times. We will not give them too much preferential treatment just because they joined our God’s project team first.
A top experimental team has never been a place to retire or sell qualifications.
If they want to keep up with the pace of our God, stay by his side, and have access to the most advanced materials and experiments, they will have to work harder than ordinary people!
The early bird catches the worm, and it is never easy to achieve nirvana through fire and transformation and improvement. This is a suffering that must be endured. If they are not understood, then they will not be understood. It is enough if their future results are beautiful and sweet.
It’s okay if it’s a bit hard now. It’s because we don’t have enough talent, so we can only make up for it with hard work!
In order to solve the material problem, Wu Tong finally turned to mathematical logic, which was her forte, to deduce the problem.
Lattice parameters: a1=a2=a3≠c, α=β=90o, γ=120o··
Al-Cu-γ-Fe-face-centered cubic
Body-centered cubic: Cr, Mo, Cs, α-Fe, δ-Fe;
······
One week, two weeks, three weeks, time has become nothingness...
Piles of manuscripts, created during her study and deduction, were piled high on the bookshelf in Wu Tong's dormitory. There were already hundreds or thousands of them. These were the accumulation of her uninterrupted study and deduction over the past few days.
Gradually, a penetrating light of wisdom appeared in Wu Tong's eyes. She thought that she was about to understand the mystery. This time, she was really going to understand it!
Wu Tong completely entered a state of enlightenment and focused his mind, and started the final breakthrough directly.
Another day of sunrise and sunset, Wu Tong, who usually goes out on time, did not go out, which attracted the attention of the security personnel responsible for her safety. While paying attention to the movement of Wu Tong's door, he called Wu Tong's daily contact number, but no one answered.
They immediately reported this anomaly to their superiors, obtained their approval, found a suitable angle, and conducted a preliminary search of Wu Tong's living room window with a telescope. This was to first confirm whether Wu Tong had encountered any special conditions and whether there were any clues in the living room.
The bedroom is an extremely private space, which is generally not the first choice unless it is an emergency.
Fortunately, they immediately saw someone sitting at the desk by the window, writing something non-stop, and they lifted the alarm that Wu Tong was in danger.
"Stay on standby!" Zheng Hongming made the decision. The security personnel would report directly to him daily, and he and Cheng Lao would also maintain contact. He knew that Wu Tong had been researching something recently and might be making some progress. They should not disturb him for the time being!
According to their understanding, Wu Tong had previously entered a state of ecstasy when he came up with the Zhou Conjecture and the Twin Prime Conjecture. Now, they wondered if Wu Tong had made a discovery that had caused him to enter this state!
If so, wouldn't they interrupt Wu Tong's inspiration and cause the loss of some world-class achievement if they interrupted him so easily? That would be a huge loss!
