Dr. Yue Zhao and Dr. Niuzhuang Yang are lecturers at the School of Instrument and Electronics of the North University of China in Taiyuan City in Shanxi Province. They are doing research on first-principles calculations of ferroelectric and ferromagnetic two-dimensional hybrid perovskite materials. We are pleased that Yue and Niuzhuang are joining our team for one year and look forward to a close and new fruitful cooperation in this area between our institutes.
