Prof. Pero Dugić, PhD, full professor visited the Chemistry Study Program of the Faculty of Natural Sciences and Mathematics at the University of Banja Luka after his retirement. As a long-time professor of the subjects I and II of the study cycle, Industrial Chemistry 2, Analytical quality control of raw materials and finished products of inorganic and organic origin, Standards and standardization, Alternative fuels and lubricants and Surfactants, his knowledge and dedication marked the work of the Chemistry Study Program.

His visit was a wonderful opportunity to talk about different topics. In a pleasant and relaxed atmosphere, memories of joint work and numerous generations of students inspired by the professor were evoked. Professor Dugić also shared his valuable experiences and advice with the audience this time, showing once again his commitment to science and the community, but also the simplicity and approachability that graced him throughout his working life.

Regardless of his retirement, we hope for further cooperation, exchange of experiences and knowledge, as well as nice socializing with a dear and respected professor.
