Chapter 218 It’s finally our Physics Department’s turn! The office was silent for three seconds. Ji Yunshi could no longer sit still. His previous leisurely demeanor was gone. He glared at him, “You old fellow, you haven’t even finished your tea yet and you’re already being disrespectful?!” "." Look, so many years have passed, and Old Ji’s mentality is still not right. Looking at his old friend blowing his beard and glaring, Tian Qilong shook his head in his heart and said helplessly: "Why don't you listen to me first?" "I'd like to hear what you have to say." Ji Yunshi chuckled twice. Tian Qilong said leisurely: "This project of Xu Qingzhou is very good, especially for the field of quantum communication, it has extraordinary significance, and Professor Pan is praising it." "." "Professor Pan?"
Ji Yunshi was originally preparing for a good battle, but when he heard this, he was stunned. Pan Jianwei is a professor at the University of Science and Technology of China. In 2003, he proposed the quantum communication satellite plan. In 2011, the Academy of Sciences' Space Science Pioneer Project was launched, becoming one of the country's key projects, and was led and promoted by Pan Jianwei. Tian Qilong smiled, took out a project application report from his briefcase and handed it to Ji Yunshi. Ji Yunshi looked at the column of project results and was completely stunned. "It is expected that there will be 2 SCI papers, and 1 in Zone 1?" “Unbelievable, isn’t it?” Tian Qilong smiled gently, "We have already looked at the three papers on this topic, and they are indeed at the top SCI level." Ji Yunshi took a deep breath and looked through the report on the project completion application. Every item was clear, logical, and written very professionally. "Old Ji, you are not in the quantum field. Professor Pan Jianwei and Professor Yang Zhongrui have jointly written a proposal to the higher authorities, hoping to strengthen the construction of quantum communication. And it has been taken seriously." "It is very likely that next year's 13th Five-Year Plan will emphasize this aspect." Tian Qilong said slowly: "In quantum communication, highly compressed QFC (quantum optical frequency comb) can improve the transmission efficiency and security of quantum bits, while in quantum computing, highly compressed QFC can be used as an important quantum resource to build more efficient quantum algorithms and quantum circuits." "So, the importance of Xu Qingzhou's research is self-evident." Ji Yunshi fell silent, feeling quite complicated, and said that the news came a little suddenly. Of course, he was still sighing about how lucky the School of Mathematics was. Xu Qingzhou had this conjecture today, that conjecture tomorrow, and won some award. As a result, the School of Mathematics appeared in everyone's topic every day. The School of Physics can also take advantage of the popularity. Now, it’s finally their turn at the Physics Department! Ji Yunshi frowned slightly and said, "But how did Professor Pan know about Xu Qingzhou's paper?" "We still have some moral integrity. Professor Chang Ciyuan saw Xu Qingzhou's paper yesterday and called to ask for his opinion. Only after he agreed did he submit it to the institute." Tian Qilong said: "Professor Pan praised the content of the paper and hoped that Xu Qingzhou could go over and help." "He is only a freshman now, with this identity." Ji Yunshi stopped.
"We are engaged in scientific research, and we speak with our strength. They mean that Xu Qingzhou can join the project as an intern. I think this is a good training opportunity for Xu Qingzhou." Ji Yunshi nodded: "Yes, this is a national project. Even if you can't participate in the core research and development, as long as you participate, you can always learn a lot." Tian Qilong took a sip of tea and said, "Our Peking University Physics Department relies on these young people." Ji Yunshi was also moved. Shuimu University's quantum anomalous Hall effect, the Chinese Academy of Sciences' neutrino oscillation, USTC's quantum communication, and even Nankai University has condensed matter physics. Speaking of Kyoto University, it seems that there is nothing remarkable to show off in recent years. The Physics Department of Peking University has always been ranked first in appearance, but some people have complained before that the prestigious Physics Department of Peking University does not have a big shot of the same level as Pan Jianwei and Xue Qikun, or has not produced results of their level. There is no way around it. The Department of Physics at Peking University started research on quantum materials too slowly. The Center for Quantum Materials Science was only prepared a few years ago. The bigwigs at the time were Academician Wang Enge and Professor Wang Jian, and the rest of the teachers were newly recruited. At the same time, the QAHE of Xue's group at Tsinghua University had already come out. Although the Institute of Quantitative Materials has made rapid progress in recent years, it is unclear how long it will take to produce any heavyweight results. Ji Yunshi was a little excited that Beijing University had a successor. In fact, disciplines have cycles. Take Nanjing University, for example, its physics was glorious for 30 years, with those veterans working until they were years old. Then they suddenly found that there was no one to take over and the research directions became highly homogenized. Nanjing University split the original School of Physics into the School of Physics + Modern Engineering + Electronics, which led to internal divisions within the school. A good hand was played poorly. Although Peking University's Department of Physics is better, its status is also precarious. In recent years, many people have put USTC first. Ji Yunshi nodded, narrowed his eyes and said, "I will discuss this matter." "Well, I have something else to do, so I'm leaving." After finishing his talk, Tian Qilong got up and left without staying any longer. In the office, Ji Yunshi finished the tea in the cup, stood up and walked towards the dean's office. Kyoto University Library. The project completion application was approved, and Xu Qingzhou finally had time to find out and read carefully the information on lithium-ion materials that he had received from Professor Zhao and his team last time. As for the paper, it was submitted three days ago. The two papers he submitted were to Physics Reports and have been accepted. This speed made Xu Qingzhou amazed. Only three days after submitting the paper, he received an email from the editor stating that it would be published in June. If the submission time could be shortened by four-fifths, it would be comparable to the speed he achieved in his previous life. In fact, there are clues to follow. He had submitted an article before, so he was an old acquaintance, not to mention that he had the recent mathematical halo hanging over his mind. Moreover, these two papers do not require a long time to argue like papers proving conjectures. Is this the life of a cheater? It is much smoother than before, and one can even say it has been a smooth road all the way. After sighing for a while, Xu Qingzhou focused his attention on the information in front of him. Professor Zhao and his team mainly studied the negative electrode materials this time, and they selected a new type of silicon-based negative electrode material. The last time I saw him, the experiment didn't seem to be going well, as too much lithium was produced.
This is indeed an obstacle to the current development of batteries, which is related to driving safety and the range that people are most concerned about. Silicon has a relatively high lithium insertion potential, which helps to avoid the formation of lithium dendrites to a certain extent, because when lithium appears on the negative electrode side, its morphology may be different due to the potential difference. However, silicon will undergo a huge volume expansion during the charging and discharging process, even up to 300%. This volume change may lead to the accumulation of stress inside the silicon particles, causing the silicon material to pulverize, which may in turn aggravate the formation of lithium dendrites. Professor Zhao and his team should not have been ruined by this. Xu Qingzhou frowned slightly, thinking about how to solve the problem. Nano-materialization? Composite? Or core-shell structure modification design? As he thought about it, he had already taken out his manuscript paper, intending to write an improvement plan from these three directions.
