Recently, the news that 26-year-old female engineering doctor Li Shengman became an associate professor in the School of Materials Science and Engineering of Hunan University has once again aroused public opinion on the post-90s scholars. The paper found that at least three post-90s scholars in the School of Materials Science and Engineering where Li Shengman is employed have been employed as associate professors and some have been employed as professors.

　　Li Shengman, who sparked the heated discussion this time, was born in 1994, focusing on the growth of nanomaterials, the processing and preparation of micro-nano electronic devices, the preparation and testing of new principle devices, and circuit design and integration. Li Shengman graduated from the School of Optics and Electronic Information of Huazhong University of Science and Technology in 2015 with a bachelor's degree in engineering. In the same year, he continued to study at the School of Optics and Electronic Information of Huazhong University of Science and Technology. Bachelor of Science. Joined the Department of Non-metallic Materials and Engineering, School of Materials Science and Engineering, Hunan University in July 2020.

　　In the School of Materials Science and Engineering of Hunan University where Li Shengman works, Li Dong, born in 1990, is already a professor and doctoral supervisor.

　　Li Dong graduated from the School of Physics and Engineering of Tongji University in 2013 with a Bachelor of Science degree. In the same year, he went on to study at the School of Physics and Engineering of Tongji University under the tutelage of Professor Zhang Zengxing. He graduated in January 2018 and was awarded a Doctor of Science degree. Joined the School of Materials Science and Engineering, Hunan University in March 2018. His main research fields are two-dimensional materials and two-dimensional material heterojunctions, including material growth dynamics, carrier dynamics inside materials, nanoelectronic and optoelectronic device preparation, physical properties and application research.

　　Another post-90s associate professor in the School of Materials Science and Engineering of Hunan University is Li Ziwei, born in Yanbian, Jilin Province in 1990. His main research fields are two-dimensional materials, nanophotonics, and new optoelectronic devices.

　　Public information shows that Li Ziwei, male, Ph.D., associate professor, doctoral supervisor, and Yue Lu scholar of the School of Materials Science and Engineering, Hunan University. Li Ziwei obtained a bachelor's degree in engineering from the School of Electronic Science and Engineering of Jilin University in 2013. In the same year, he was recommended to study for a Ph.D. In 2017 and 2019, he was a visiting scholar at the Metamaterials Center of the University of Birmingham, UK, and the Department of Physics, Linköping University, Sweden. In June 2018, he obtained a PhD in Condensed Matter Physics from Peking University, and joined the School of Materials Science and Engineering of Hunan University in July of the same year.

　　In addition, Yu Chuying, who joined the School of Materials Science and Engineering of Hunan University as an assistant professor in October 2017, was appointed as an associate professor in January this year. Yu Chuying, born in 1990, is a Ph.D. from the School of Materials Science and Engineering at Queen Mary, University of London. His research field is the basic and applied research of advanced energy materials, and the preparation and performance characterization of new supercapacitor electrode materials.

　　The Department of Materials of Hunan University originated from the Mining Department of Hunan Higher Industrial School opened in 1903. In 1943, the Department of Mining and Metallurgy of National Hunan University began to recruit graduate students. In 1958, the majors of silicate, casting, metal anticorrosion, and metal physics were established. In 1986, he was granted the right to confer a doctorate degree in the second-level discipline of materials science, and in 2000, he was awarded the right to confer a doctorate degree in the first-level discipline of materials science and engineering. At the same time, the School of Materials Science and Engineering was established. In 2001, a post-doctoral mobile station was established. In 2011, the major of materials science and engineering was rated as a national specialty.

　　According to the official website of the School of Materials Science and Engineering of Hunan University, the college has a high-level full-time faculty of reasonable age and structure. There are currently 105 full-time teachers, 54 full-time doctoral supervisors and 49 professors; and 37 Yuelu scholars from Hunan University , The proportion of teachers with a doctorate degree is 99%, and the proportion of teachers who are introduced overseas and have more than one year of study abroad experience is 67%.
