It was surprisingly quiet downstairs in the laboratory building. The only sounds in the air were the hot breeze and the slightly impetuous chirping of cicadas.
At this time, everyone had their own things to do. Some of them planned to go back to finish the homework assigned for the main course in the morning while there was still a lot of time before the afternoon class. Some people had to go back to the nearby rental house to pick up the afternoon textbooks, and some had to go to their own clubs... But so far, seeing the boy and girl going to the library, they were unable to move for a while, as if they had forgotten the urgent tasks at hand.
Who is this passerby who suddenly appears
In this science and technology competition team, the girls who gradually became close to Jiang Hongshao gathered together after they walked away, and kept looking at Cheng Ran's back.
Yuan Huiqun, who was beside Qin Qian, opened her eyes wide and made a mouth shape to Zhang Ping, which was "What's going on? What's going on?"
Zhang Ping also shook his head in shock and confusion, "I don't know what the relationship between the two of them is..."
Qin Qian fell silent, looked in the direction of the library, and pursed her thin lips.
For the participating teams present, no matter what the relationship between Cheng Ran and Jiang Hongshao is, what they care about most is what Jiang Hongshao said.
Now their team has encountered a problem, which even directly affects whether the project can be carried out. However, time is tight and the project has been submitted. Even if it is feasible to make a temporary change, it is too late from the perspective of preparation.
The instructor asked for help from his university professor, but the problem was that the knowledge was still insufficient. The so-called scientific and technological innovation was the path they took, and they always had to come up with something that their predecessors had not, even if the current research was very superficial, but at least it was innovation. But they underestimated the difficulty. A feasibility study on lithium batteries was not something they could successfully complete with their knowledge.
This is where the embarrassment lies. Since those present have signed up for this science and technology competition, they are all the best students in this area in the grade. Of course, not all the best students will come to sign up, but when everyone was forming this team, they had a discussion. The responsible instructor also asked other subject teachers in the teacher's office about students with good grades in this area, and also mentioned to these students, "There is a science and technology competition, you are good at this, do you want to participate, save money to win a prize, and help with further studies..."
The students in the team knew who was better, but they had never heard of a person named "Cheng Ran".
Jiang Hongshao also told him about the current predicament she was facing, and invited him to the library to discuss this problem with him in his free time... This also meant that he was qualified and even had a good personal relationship with Jiang Hongshao.
Who is this person!
Su Yang withdrew his gaze, and only then noticed that Qin Qian was also staring in that direction. Then, as if she noticed something in Su Yang's eyes, she turned her head, and the two of them met eyes, but said nothing.
For the first time, an inexplicable and awkward silence arose between them.
After a while, Su Yang said, "Your new friend seems to be good at this?"
Qin Qian said "Oh".
Su Yang looked towards the library again and said, "But even the team can't find a solution to this problem in a short time... It can't be solved by one or two people..."
…
Jiang Hongshao and Cheng Ran walked side by side through the path lined with ginkgo and banyan trees. In fact, they had been seen by many people, but it did not cause much reaction. This was because Jiang Hongshao herself had a lot of things to do, so she often did not act alone. Sometimes she was accompanied by someone, sometimes a boy, who was usually a celebrity like Zhu Xu or Liao Houming, who was the vice president of the student union. So it was not uncommon for her to see such a person.
But when the two of them walked side by side into the red door of the library with ivy growing all over the top, everyone who saw them here blinked their eyes in disbelief.
Loud noises are not allowed in the library, so you can often see couples, or boys and girls who like each other, studying in this quiet place, occasionally whispering.
In No. 10 Middle School, if a boy and a girl eat together outside, perhaps no one thinks there is anything wrong with it, but the library is a magical place. If two people walk into the library side by side, it means a lot. There will be comments like "So-and-so walked into the library together, are they having fun?", which will often be confirmed afterwards.
For No. 10 Middle School, the library is simply the number one holy place.
As the two of them walked in, they bumped into the students who were coming out. When a little boy saw Jiang Hongshao, his face turned red and he turned around and walked back to the library. This was a normal reaction for a shy boy who would think that the girl he liked was a monster.
A group of men and women seemed to have sprained their waists unexpectedly. They looked at the two people incomprehensibly with strange smiles on their faces, turned their heads in their direction and then passed by.
At the study table, someone looked up and saw this scene, and quickly nudged his friend next to him with his elbow. When the other person rubbed his arm in pain, he pointed to the front with the corner of his mouth to signal for him to look quickly!
There were also girls who knew Lao Jiang and waved to her, but they stared at Cheng Ran without blinking the whole time. They looked as if they wanted to interrogate him thoroughly. If possible, Cheng Ran felt that she would say something like "turn around and put your hands on the wall".
Needless to say, this scene in the library will soon spread widely.
After leading Cheng Ran to the reading room, Lao Jiang said, "Wait for me."
Then she went to the relevant cabinets to get reference books. Cheng Ran sat on a chair and saw her frowning, thinking, and standing on tiptoe to get books in different cabinets. Even turning the pages of a book was quite pleasing to the eye.
After a while, she took out six or seven books, hugged them with both hands, and put them on the table. During this time, Cheng Ran wanted to go over to help her, but she said softly, "No need." She looked like she could do things by herself.
This really requires some research... Isn't it a bit of a waste of such a beautiful scenery
Sitting down in front of Cheng Ran, Jiang Hongshao glanced at him, reached into her trouser pocket, took out a pack of toilet paper, pulled out a piece of paper and handed it to him.
Cheng Ran was stunned, "Huh?"
Jiang Hongshao said, "Wipe your mouth, it's so greasy..."
Cheng Ran wiped it with paper in astonishment.
Jiang Hongshao said, "You are good... You have made new friends so quickly. You are popular."
Cheng Ran felt that the corners of his mouth seemed a little stiff, "It was just an accident..."
Jiang Hongshao opened the book and read it, but she seemed to be able to do two things at once, "This Qin Qian is quite famous... She is a girl who truly loves dancing. A dancer's confidence is pure, and her vanity and arrogance have long been polished away through constant practice. I have seen her dance, and she is able to control her movements freely. She has reached a very high level, and it cannot be achieved without a corresponding state of mind."
"You praised me so highly, did you also praise yourself?" Cheng Ran thought of her dancing skills in the art performance that year.
"No, she is a professional..." Jiang Hongshao said, "I am just an amateur and I know a little bit."
Then Lao Jiang smiled again, "After all, I should thank her."
"Thank you for what?"
"Thank you for treating a pig like you to food when I was busy... It saved me a lot of money."
"… "
Cheng Ran knocked on the table and said solemnly, "What do you mean by your last sentence? Are you not going to take me out to eat?"
Jiang Hongshao rolled her eyes at him and said, "No money."
Cheng Ran smiled dazzlingly, "Then I'll treat you."
Jiang Hongshao was stunned for a moment, her eyes flickering, "It depends on my mood."
There was silence between the two.
Cheng Ran looked at her with a smile. She buried her head in the book, her ears slightly red.
After a pause, Cheng Ran said, "Didn't you ask me to help you with the difficulties you encountered in the project? Why don't you ask me for advice?"
"Excuse me?" Jiang Hongshao raised her head and looked at him with an expression that was not sure whether she was angry or amused. After thinking for a while, she stretched out a tender finger and pointed at the pile of books on the table, such as "Battery Principles", "Overview of Rocking Chair Batteries" and "Lithium Ion Research".
This time, she teased with a smile, "If you can finish reading all of this within three days, I will ask you for your advice..."
Cheng Ran smiled, "No need, I will answer you now. You are looking for a more stable battery silicon negative electrode material is purely wishful thinking. Silicon-based materials do have better capacity than carbon-based materials, but silicon materials will expand severely during the lithium embedding process, resulting in a large loss of capacity. Why not... try carbon-silicon composite materials? This is the future."
It was not until 1992 that lithium-ion batteries were successfully developed, which greatly reduced the weight and size of portable electronic devices such as mobile phones, notebooks, and calculators in human society. However, this era was still at the forefront of related fields.
In the future, Tesla's electric car will have a unique battery technology and use carbon-silicon composite materials as its negative electrode material.
Of course, this more in-depth field is the result that can only be obtained after a lot of scientific demonstration and practice in the laboratory. Jiang Hongshao and his colleagues' research topic is merely an exploration of feasibility.
This conclusion alone is probably enough to deal with their topic.
The words awakened the dreamer. Jiang Hongshao looked at him with bright light in her pupils.
