On November 8, 2019, At 15:00 p.m,Professor Konstantin I. hadjiivanov(vice president of Bulgarian Academy of Sciences) visited the School of Chemistry and Materials Engineering, and held a lecture on the theme of "understanding processes on solid surfaces using spectrum" in A308 of the School of Chemistry and Materials Engineering. Mr. Pan Qingwei (Secretary of the Party committee of the School of Chemistry and Materials Engineering) presided over the lecture. In the lecture, Professor Konstantin I. hadjiivanov demonstrated the infrared spectrum test method under the adjustable external environment, and described the red or blue shift phenomenon of infrared spectrum under the condition of absorbing carbon dioxide and nitrogen by single crystal, powder and porous materials, as well as listed the scientific problems of infrared spectrum change in the process of oxidation-reduction and summarized the rules. In the lecture, Professor Konstantin I hadjiivanov told the questions about infrared spectroscopy through various examples, and answered the questions put forward by the teachers and students of the School of Chemistry and Materials Engineering.
Professor Konstantin I. hadjiivanov is currently vice president of the Bulgarian Academy of Sciences and director of the Institute of chemistry of the Bulgarian Academy of Sciences. His research focuses on surface chemistry, adsorption and catalysis with environmental impact. So far, he has published more than 300 research papers, cited more than 10000 times independently, and h-index > 54. Professor hadjiivanov is an academician of the European Academy of Sciences and the Bulgarian Academy of Sciences.
