On June 24, 2025, the thesis defense of the third-year graduate student of the Department of Chemical Technologies and Resource Saving, assistant professor at the Department of Industrial Pharmacy of KNUTD Vadym LISOVYI defended his dissertation for the degree of Doctor of Philosophy (PhD) in the specialty 161 Chemical Technologies and Engineering. Under the supervision of Doctor of Technical Sciences, Professor, Professor of the Department of Industrial Pharmacy Volodymyr BESSARABOV, Vadym LISOVYI completed and successfully defended his dissertation “Development of a polymeric solid dispersed system for pharmaceutical use using the centrifugal fibre formation”.
The defense took place at a one-time specialized academic council, which included: chairman – Doctor of Technical Sciences, Professor, Associate Professor of the Department of Chemical Technologies and Resource Saving of KNUTD Volodymyr KHOMENKO; reviewers – Doctor of Technical Sciences, Professor, Professor of the Department of Chemical Technologies and Resource Saving of KNUTD Bohdan SAVCHENKO and Candidate of Technical Sciences, Associate Professor, Associate Professor of the Department of Chemical Technologies and Resource Saving of KNUTD Iryna LIASHOK; official opponents: Doctor of Chemical Sciences, Professor, Head of the Department of Polymer Modification at the Institute of Chemistry of Macromolecular Compounds of the National Academy of Sciences of Ukraine Serhii RIABOV and Doctor of Technical Sciences, Professor, Professor at the Department of Chemical Technology of Plastics Processing of Lviv Polytechnic National University Oleksandr HRYTSENKO.
Vadym LISOVYI's dissertation research is highly relevant both in the context of the development of modern scientific knowledge and in terms of its practical significance. The work develops an innovative technology for obtaining the polymer composite material flavonoid hesperidin in the form of solid dispersed systems using the method of centrifugal fiber formation in accordance with the principles of “green chemistry”. This approach has made it possible to significantly increase the solubility of hesperidin in aqueous media – by 170.7 times, which is crucial for improving its bioavailability and pharmacological efficacy.
The proposed technology has high potential for scaling up and implementation in production processes at modern chemical and pharmaceutical enterprises. Its implementation expands the technological capabilities for creating active pharmaceutical ingredients with antioxidant effects using hesperidin and will contribute to the development and launch of a new generation of socially oriented drugs based on them on the pharmaceutical market.
Members of the ad hoc specialized academic council noted that Vadym LISOVYI's dissertation is an interesting and original study, which was carried out at a high scientific and technical level and, in terms of its relevance, degree of novelty, formulation and method of solving the issues raised, theoretical and practical basis, and the validity of the results obtained, meets the requirements of the Procedure for awarding the degree of Doctor of Philosophy and repealing the decision of the ad hoc specialized academic council of a higher education institution or scientific institution on awarding the degree of Doctor of Philosophy, approved by Resolution of the Cabinet of Ministers of Ukraine No. 44 of January 12, 2022. We sincerely thank all members of the one-time specialized academic council for their professional assessments and positive reviews of the dissertation.
The diploma of awarding the scientific degree of Doctor of Philosophy in the field of knowledge "Chemical and Bioengineering" with the specialty "Chemical Technologies and Engineering" was officially presented to Vadym at a meeting of the University's Academic Council on July 30, 2025.
This remarkable achievement was a logical confirmation of Vadym's many years of hard work, his high qualifications, and deep dedication to science. For over 8 years, he has been a member of the Department of Industrial Pharmacy at KNUTD and has been actively involved in educational projects and research work at the university. Vadym's significant publication record testifies to his systematic research work, perseverance, effectiveness, and active scientific position.
His scientific supervisor, Doctor of Technical Sciences, Professor Volodymyr BESSARABOV, made a very important contribution to the professional growth of the young specialist. His professional support, valuable advice, and inspiring mentorship became an integral part of the results achieved.
The staff of the Department of Industrial Pharmacy at KNUTD sincerely congratulates Vadym and his research supervisor! We wish the young scientist further success in his professional activities and active shaping of Ukraine's scientific future! May the academic degree he has earned become a solid foundation for further professional achievements, international scientific recognition, and the implementation of innovative ideas. We are confident that Vadym and his scientific advisor have many new joint achievements and victories ahead of them!
