Wu Jianxiong College: an honorary College of training top innovative talents in Southeast University
President you first introduced the situation of Wu Jianxiong college. Wu Jianxiong college is an honorary College of Southeast University for training top innovative talents. It is named after Mr. Wu Jianxiong, a famous physicist and outstanding alumnus of Southeast University. Mr. Ding Zhaozhong, a famous physicist and Nobel Prize winner, was employed as honorary Dean of the college. Professor Zhang Guangjun, academician of the Chinese Academy of engineering and President of Southeast University, concurrently serves as the dean of the college.
Wu Jianxiong college adheres to the education concept of "excellence, individuality and internationalization", aims to gather high-quality resources and cultivate elite talents, and gathers high-end resources of the whole school to cultivate outstanding talents. The advantages of the college are "three 100%", i.e. 100% majors are optional, and students can choose freely within all four-year science and engineering majors of the whole school; 100% tutors are equipped, each student is equipped with two tutors, one is the College Tutor responsible for students' academic development, subject interest, general education and life growth, the other is the national famous teacher and Yangtze River scholar Invite professors and other elite professors to serve as academic mentors to lead students to experience real scientific research and apply their learning; 100% of students will have at least one exchange learning, International Conference and other overseas learning and exchange experience.
In addition, the college also provides a platform for students to organize and participate in various extracurricular activities, and invites high-end teachers at home and abroad to provide high-quality courses, so that students can spend a colorful and unique four-year wonderful learning life.
A strong academic atmosphere fosters a number of excellent students. According to previous data, more than 80% of Wu Jianxiong's students choose to continue their studies after graduation, of which nearly 50% enter the first-class domestic universities and scientific research institutions, and nearly 30% go to the top foreign universities for further studies.
To achieve a leap forward breakthrough from running parallel to leading -- molecular ferroelectric research team of Southeast University
Then president you shared his research field. President you is an outstanding scholar with remarkable achievements. During his time in Southeast University, his team published 34 SCI papers in the past five years, with a total of more than 2000 citations, including two science papers and the first nature.phys of Southeast University. President you started from the nature of dielectrics and reviewed the research process of ferroelectric materials. He mainly introduced the development process of molecular ferroelectrics research in Southeast University for more than ten years.
Ferroelectrics is a special functional material, which is widely used in national defense, aerospace, communications and other fields. With the development of technology, the manufacture of lighter, thinner, more sensitive and more environmentally friendly ferroelectric materials has become a research hotspot. In 2006, Professor Xiong rengen established the research center of ordered Matter Science in Southeast University, and began to systematically study the design and synthesis of molecular ferroelectric materials in China. Professor Xiong rengen's team is committed to the development of new molecular based ferroelectric materials with light weight, flexibility, rich functions, non-toxic and environmental protection, in order to become a useful supplement to the traditional inorganic ferroelectric ceramics. Because of the particularity of molecular materials in composition and structure, it has been considered that it is an impossible dream to realize the performance of inorganic ceramics in molecular system. Until 2013, Professor Xiong rengen developed a new molecular ferroelectric material, diisopropylamine bromide (dipab). This is the first time that molecular materials can keep pace with inorganic materials in ferroelectric properties in the past hundred years, marking that China's molecular ferroelectric research has reached the level of parallel with international top teams.
In 2014, president you formally joined the "research center of orderly material science", and his interdisciplinary research background also injected fresh blood into the team. In 2017, the team synthesized a new type of molecular piezoelectric materials, whose piezoelectric coefficient reached or even surpassed the traditional one-component inorganic ceramic barium titanate. In 2018, the team developed the world's first non-metallic Perovskite Ferroelectric Material and published the third science paper. Its excellent performance has attracted wide attention of the international academic community. The results were reported on the websites of many professional academic institutions, including the IOP, AAAs and ACS. The above achievements represent that China's molecular ferroelectrics research has reached the world-class leading level.
In 2017, relying on the "ordered material science research center", Jiangsu provincial "molecular ferroelectric science and application" key laboratory was established. And in 2019, with the special support of "top ten scientific and technological issues" of Southeast University, the special academic zone of "International Molecular ferroelectric science and Application Research Institute" was established. After more than ten years of hard exploration, the outstanding scholars of the team have made the breakthrough of "from zero to one" in the international research of molecular ferroelectrics in China. At present, the team has published four science papers and more than 50 papers in other top international journals, and has developed nearly 100 kinds of new molecular materials, ranking first in the world in the research on the key properties of molecular ferroelectric materials, and maintaining the international leading position in the research of related fields.

Interactive Q & A
Q: Could you please talk about the next step of "academy system" of Wu Jianxiong college? What's the "academy system" in your mind?
Professor you: we always hope to build Jianxiong academy into a platform for gathering and exchanging elite students, high-end tutors, management backbones and outstanding scholars outside the University. We plan to invite famous masters in the field of higher engineering technology as honorary Dean and Dean of "Jianxiong academy"; organize college tutors and professional tutors to guide students' scientific research life and life direction; in addition, the "Jianxiong academy" communication space project located at the bottom of the eight buildings in Taoyuan has been basically completed, with modern decoration design, and will become a student branch after completion Research, discussion, extracurricular activities and leisure are good places. This is also the first exchange space of the Academy in the campus of Dongda.
In terms of the development of the Academy, first of all, I just mentioned the improvement of the management structure including the appointment of the dean. Secondly, the Academy implements the double tutor system. Each Wu college student can contact many college tutors during his study in the Academy, and choose the professional master who will eventually guide his study. The College Tutor is not a counselor, but an outstanding young scholar, management backbone elite and outstanding peer elders selected in the whole school. It provides comprehensive guidance for students in college life, life choice and future development, and interacts with students in course selection, reading and interest. Academic tutors are usually young and middle-aged academic leaders. They form a pair with students of Wu University. Students can start the research road under the guidance of academic tutors. Freshmen can directly enter the tutor's laboratory, communicate with their doctoral brothers and sisters, and experience the scientific research daily life of world-class laboratories. Third, the college implements a comprehensive credit system to separate the first and second classroom credits. The first class is mainly about curriculum training. The second class puts forward more requirements for students' scientific research ability, humanistic quality and personal quality. Welcome to Jianxiong academy!
Q: It's reported that Mr. you likes drawing very much. What's the relationship between humanity and Science in your mind?
Professor you: in fact, my painting is completely due to my interest, and I have not received professional training. I think the students of science and engineering must have basic humanistic quality, not to do science can only have cold logical thinking. AI's computing power far exceeds that of human brain, and where human beings surpass machines is our perceptual thinking, which is sometimes the source of innovation. In addition to the regular formula deduction, a little rebellion, sentiment or sadness will bring you infinite reverie, infinite possibility, and then ideological breakthrough. Learning a musical instrument, reading a little history and cultivating an interest can give yourself a chance to relax and add some meaning to the leisure life besides the heavy scientific research. So I hope the students of science and engineering don't neglect the humanities. In addition, I also recommend humanities students to read some popular science books in their spare time, because many times the development of human civilization and art, such as sculpture and music, is also based on scientific breakthroughs, and the understanding of science and technology will help us to carry out research in history and art.
Q: As a doctoral student who just returned to school, the efficiency of home-based research work is very low these days, which also disrupts the original experimental plan, so he is very anxious. Would you like to hear what you have learned from your scientific research during this period of time? Is there any tips you can share with you?
Professor you: because a lot of our work needs to be done in the laboratory, our progress during this period is also affected by the epidemic. But I think it's a good opportunity for me to find out and fill in the missing books and lessons that I didn't have time to read or take before. Especially in this period of time, I found that the network resources are very rich. There are many courses carefully prepared by MOOC and national famous teachers, so if you can't enter the laboratory for the time being, you can enrich this period of time by reading books, listening to lectures and supplementing basic knowledge. In addition, I think this is also a good opportunity to mine previous work and sort out previous experimental data. Sometimes when the experiment is finished, the paper is published at the first time. Maybe the small achievements buried under the advanced achievements are ignored at that time. In fact, the information and discovery contained in a data is far more than a completed paper, so we can continue to mine. If you still have enough time, you can learn another foreign language, such as Japanese and German, to improve your humanistic quality.
Q: As a student of Wu Jianxiong college, he will face professional choice and always develop in the public
