Chapter 72 Superconductor Material Niobium Titanium Alloy
After waiting for about a minute, a tall and thin young man ran down and waved to Xu Qingzhou.
The young man had two big dark circles under his eyes and a sallow complexion. Judging from Xu Qingzhou's experience, it doesn't take a few long nights to show signs of kidney deficiency.
After the young man confirmed that Xu Qingzhou was the person he wanted to lead, he took the initiative to introduce: "Junior brother, my name is Wang Wei. If you don't mind, you can just call me Senior Brother Wang."
"Senior Brother Wang." Xu Qingzhou said with a smile.
"Come with me, the teacher is waiting up there." Wang Wei took Xu Qingzhou into the experimental base, "Junior brother, you are already a senior, are you going to prepare for a project this semester?"
"Senior brother, I am a freshman." Xu Qingzhou explained.
Wang Wei's steps trembled, he almost staggered, and he shouted out loud: "You are a freshman?!"
Xu Qingzhou nodded.
Wang Wei is confused. Nowadays, students are so good. Can they enter the professor's project in their freshman year?
Following Wang Wei into the laboratory building, Xu Qingzhou soon saw Zhao Risheng, who was directing something in front of the instrument. He looked energetic and worked vigorously, completely different from the steady old man before.
"You are Xu Qingzhou, right?" Zhao Shengwen finished instructing the short-haired girl and looked at Xu Qingzhou. He was speechless and said, "Young people are scary. When I was your age, I was still ignorant. I thought about how to play all day long."
"You're flattered." Xu Qingzhou smiled and shook his head.
In addition to Zhao Shengwen, there are three people in the project, Wang Wei, another fat young man, and a girl with a smart short haircut.
The fat man came over and saw Wang Wei's expression was strange, so he asked: "Viagra, what's wrong with you?"
"Junior brother Gong, I took a look and there seems to be something wrong with the superconducting transition temperature (Tc) measurement data you submitted yesterday. Do you want to calculate it again?"
Wang Wei narrowed his eyes and hugged Gong Yunfei.
"Senior Brother Wang, I was wrong." Gong Yunfei quickly begged for mercy.
Zhao Shengwen ignored the two students who were fighting. The laboratory was boring, and it was okay to have a little fun occasionally. He clapped his hands and said, "Let me introduce to you. This classmate's name is 'Xu Qingzhou'. He comes from the School of Mathematical Sciences and will join in the future." Our project team.”
In fact, if someone else introduced him, he would definitely have to test whether the other person was qualified, but since the recommender was Gu Zhizhong, there was no need.
Xu Qingzhou greeted: "Brothers and sisters, my name is Xu Qingzhou. Please give me your advice in the future."
"Welcome, junior brother." The boy who was talking to Wang Wei introduced himself: "My name is Gong Yunfei. If you need anything, just come to me."
The short-haired girl was in front of the superconducting quantum interferometer. At this time, she also looked at Xu Qingzhou, without showing much enthusiasm, and said slowly: "Hong Yayu."
Xu Qingzhou didn't think there was anything wrong. He could tell that this senior sister was a type of person who only focused on experiments and liked to work hard.
"By the way, Xiao Xu, you are only a freshman now, please take more care of me." Zhao Shengwen warned.
"What, freshman?!" Gong Yunfei took a breath and stared at Xu Qingzhou in disbelief.
Even Hong Yayu, who had always been cold, looked up at Xu Qingzhou with surprise in his eyes.
"Yes, I just finished military training." Xu Qingzhou replied "shyly".
"My dear, junior brother, you are so awesome." Gong Yunfei gave a thumbs up.
After introducing the new team members, Zhao Shengwen waved his hand and said, "Xiao Wang, please go back and rest quickly."
Wang Wei did not insist and said to Xu Qingzhou: "Junior brother, see you tomorrow." After Wang Wei left, Zhao Shengwen signaled Gong Yunfei and Hong Yayu to get busy first, and told Xu Qingzhou about the project status.
"We are doing an analysis of the electromagnetic properties and heat conduction of the superconducting material niobium-titanium alloy. Niobium-titanium alloy superconductors are widely used in the manufacturing of superconducting magnets, especially in magnetic resonance imaging (MRI), which can improve the resolution and resolution of MRI imaging. Clarity.
"Optimizing the performance of niobium-titanium alloy superconductors will help improve the performance and diagnostic accuracy of MRI equipment."
"At present, this field has been monopolized by foreign countries for a long time. We, Xia Guo, have to pay terrible costs every year. Although domestic companies such as United Imaging and Otech are currently catching up, there is still a big gap."
"If this project succeeds, it will be a good thing for the country and the people for a long time to come."
"In addition, this project of our research group is supported by the Kyoto University Experimental Project Fund and the Kyoto Ministry of Health Scientific Research Fund. Participating in this kind of project will be quite helpful for your personal resume and future development."
Xu Qingzhou nodded from time to time and had a general understanding of the project.
Niobium-titanium alloy superconductors have a high upper critical magnetic field, about 11T at 4.2K and about 14T at 2K, which means that in MRI equipment, stronger magnetic fields can be generated using niobium-titanium alloy superconductors.
He was really interested in this, and he roughly knew that his work probably involved mathematical tools such as Maxwell's equations and the heat conduction equation.
Following Zhao Shengwen around the laboratory, Xu Qingzhou saw various equipment that he was very familiar with, such as the superconducting quantum interferometer (SQUID), scanning electron microscope (SEM), and transmission electron microscope (TEM).
"We The thermal conductivity performance test is being carried out now, and your job is to work with Xiao Wang on data processing and analysis, and to establish a mathematical model. "
Xu Qingzhou followed Zhao Shengwen into another office, "This is where we sort the data."
Zhao Shengwen pointed to the seat by the window, "I've asked them to clean up your desk."
At this time, Zhao Shengwen's phone suddenly rang. After answering the phone, he said to Hong Yayu, who came in after the experiment: "Xiao Hong, I have to go to the Materials Research Institute. Xiao Xu leaves it to you. Give me the information." Give it to him, let him get familiar with our project first, and then take him to apply for the access card."
"I understand, teacher." Hong Yayu nodded.
After the arrangements were made, Zhao Shengwen left with peace of mind.
Hong Yayu looked at Xu Qingzhou and asked, "Junior brother, do you know how to use programming software such as MATLAB and Python?"
"I know a little bit." Xu Qingzhou was very modest.
Hong Yayu nodded, rummaged through the drawer for information for Xu Qingzhou, and asked, "Where is COMSOL Multiphysics?"
"Also a little bit." Xu Qingzhou continued to nod.
COMSOLM Multiphysics is a multi-physics simulation software that can build complex physical models. He has used it quite a lot before.
"A little bit is enough. As long as you have the basics, you can learn the rest slowly."
With that said, Hong Yayu handed over a USB flash drive and said seriously: "Junior brother, all the information about our project is here, including the documents you need to read, software usage tutorials, etc. You can come down and read more, but these are all This is internal information and cannot be shared externally.”
"I know." Xu Qingzhou nodded.
"Senior sister, don't scare the younger brother." Gong Yunfei came over, patted Xu Qingzhou's shoulder, and explained with a smile: "Although there is cooperation between universities, they are actually competitive, and they are competing secretly, so All information needs to be kept strictly confidential.”
"For example, our project is also being worked on by Jinling University. Whoever comes up with it first will get the result."
Xu Qingzhou finally understood why Zhao Shengwen and the others were so anxious. Indeed, once the other party produces results first, it means that all their efforts will be in vain.
