Chapter 72 Superconductor Materials Niobium-Titanium Alloy After waiting for about 1 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 his face was sallow. Based on Xu Qingzhou's experience, it was impossible for him to suffer from kidney deficiency after staying up late for a few nights. After the young man confirmed that Xu Qingzhou was the person he wanted to take with him, he took the initiative to introduce him: "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 upstairs." Wang Wei took Xu Qingzhou into the experimental base, "Junior brother, you are already a senior, right? Are you going to prepare for the thesis this semester?" "Senior brother, I'm a freshman." Xu Qingzhou explained. Wang Wei's steps trembled, and he almost stumbled, and he shouted out: "You are only a freshman?!" Xu Qingzhou nodded. Wang Wei was confused. Students nowadays are so awesome that they can 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 in a hurry, completely different from the steady old man he used to be.
"You are Xu Qingzhou, right?" Zhao Shengwen finished instructing the short-haired girl, looked at Xu Qingzhou, and was amazed, "You are young and promising. When I was your age, I was still ignorant and thought about how to have fun all day long." "You're too kind." Xu Qingzhou smiled and shook his head. In addition to Zhao Shengwen, there are three people in the project, Wang Wei, another slightly plump young man, and a girl with a neat short haircut. Wei Pang came over and saw Wang Wei's strange expression, so he asked, "Brother Wei, what's wrong with you?" "Junior Brother Gong, I took a look and the data you submitted yesterday on the measurement of the superconducting transition temperature (Tc) seems to have some problems. Do you want to calculate it again?" Wang Wei narrowed his eyes and hugged Gong Yunfei. "Senior Brother Wang, I was wrong." Gong Yunfei begged for mercy quickly. Zhao Shengwen ignored the two students who were playing around. The lab was boring, so it was okay to have some fun occasionally. He clapped his hands and said, "Let me introduce you to this student, Xu Qingzhou, from the School of Mathematics, and he will join our project team from now on." In fact, if the person was introduced by someone else, he would definitely have to test whether the other party was qualified, but since the recommender was Gu Zhizhong, there was no need to do so. Xu Qingzhou greeted them: "My fellow brothers and sisters, my name is Xu Qingzhou, please give me your guidance in the future." "Welcome, junior brother." The boy who was talking to Wang Wei introduced himself: "My name is Gong Yunfei. If you have any questions, please feel free to contact me." The short-haired girl was standing in front of the superconducting quantum interference device. She looked at Xu Qingzhou without much enthusiasm and said slowly, "Hong Yayu." Xu Qingzhou didn't think there was anything wrong. He could see that this senior sister was the type of person who only focused on experiments and liked to work hard. "By the way, Xiao Xu is only a freshman now, so you guys should take care of him." Zhao Shengwen reminded. "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. "Yes, I just finished military training." Xu Qingzhou answered "shyly". "Oh my goodness, 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, go back and have a rest."
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 go ahead and he told Xu Qingzhou about the project situation. "We are analyzing the electromagnetic properties and thermal conductivity of the superconductor material niobium-titanium alloy. Niobium-titanium alloy superconductors are widely used in the manufacture of superconducting magnets, especially in magnetic resonance imaging (MRI), which can improve the resolution and clarity of MRI imaging. "Optimizing the properties of niobium-titanium alloy superconductors will help improve the performance and diagnostic accuracy of MRI equipment." "This field has long been monopolized by foreign countries, and our Xia country has to pay horrific costs every year. Although domestic companies such as United Imaging and Aotai are catching up, there is still a big gap." "If this project is successful, it will benefit the country and the people for generations to come." "In addition, this project of our research group is supported by the Kyoto University Experimental Project Fund and the Kyoto Health Ministry Scientific Research Fund. Participating in such a project is very 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 at 11K and about 2T at 14K, which means that in MRI equipment, the use of niobium-titanium alloy superconductors can generate stronger magnetic fields. He was really interested in this, and he knew in his heart that his work would probably involve mathematical tools such as Maxwell's equations and heat conduction equations. Following Zhao Shengwen around the laboratory, Xu Qingzhou saw various equipment that he was once very familiar with, including superconducting quantum interference device (SQUID), scanning electron microscope (SEM), and transmission electron microscope (TEM). "We are currently testing the thermal conductivity performance. Your job is to work with Xiao Wang to process and analyze the data and build a mathematical model." Xu Qingzhou followed Zhao Shengwen into another office, "Here is where we organize the data." Zhao Shengwen pointed to the window and said, "I've asked them to clean up your desk." At this time, Zhao Shengwen's phone suddenly rang. After answering the call, he said to Hong Yayu who came in after finishing the experiment: "Xiao Hong, I have to go to the Materials Research Institute. I'll leave Xiao Xu to you. Give him the information and let him get familiar with our project first. I'll take him to get an access card later." "I understand, teacher." Hong Yayu nodded. After making the arrangements, 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?" "A little bit." Xu Qingzhou was very modest. Hong Yayu nodded, rummaged through the drawer to find the information for Xu Qingzhou, and asked, "Where is COMSOL Multiphysics?" "I know a little bit." Xu Qingzhou continued to nod. COMSOL Multiphysics is a multi-physics simulation software that can build complex physical models. He used it quite a lot in the past. "A little bit is enough. As long as you have the basics, you can learn the rest slowly." Hong Yayu handed over a USB drive and said seriously, "Junior brother, all the information about our project is here, including the documents you need to read, software tutorials, etc. You can take a look at them when you come down, but these are internal materials and cannot be passed on." "I know." Xu Qingzhou nodded. "Sister, don't scare me." Gong Yunfei came over, patted Xu Qingzhou on the shoulder, and explained with a smile: "Although there is cooperation between the universities, they are actually in a competitive relationship and are secretly competing with each other, so information and the like need to be kept strictly confidential." "For example, our project is also being worked on by Jinling University. Whoever gets it first will own the results." Xu Qingzhou finally understood why Zhao Shengwen and the others were so anxious. Indeed, if the other party produced results first, it would mean that all their efforts would be in vain. (End of this chapter)
