1. Scientific School “Development of technology for manufacturing and research of physico-chemical, technical and operational characteristics of new functional materials and coatings”. Year of foundation – 1982, a founder – Prof. J. L. Roikh, current leaders are Prof. S. N. Fedosov and Prof. A.E.Sergeeva. The direction of research of the scientific school – “New materials” – refers to the priority directions of science and technology development of Ukraine (Law of Ukraine № 2623-SH).
The main direction of scientific activity of the school: “Investigation of electrophysical properties of polymeric dielectrics intended for the development of new devices, elements and systems”.
Studies in the field of the dielectrics physics are considered as a fundamental research, which make a significant contribution to the development of this branch of science.
The results of the research have received world recognition and are published in such prestigious international physical journals as Journal of Applied Physics, Applied Physics Letters, Ferroelectrics, Transactions of IEEE, etc. A new concept of the relationship between polarization and volume charge in polymeric ferroelectrics and electrets promoted by ONAFT scientists was further developed in the joint works of our professors with leading foreign scientists such as Prof. H. von Seggern (Darmstadt Technical University, Germany), Prof. J. Marat-Mendez (New Lisbon University, Portugal), Prof. J. A. Giacometti (University of São Paulo, Brazil). The staff of the department actively participates in international scientific forums, conferences and symposiums. The research results are introduced into the educational process at the courses of general physics, section “Electrostatics: properties of dielectrics”, as well as in special courses in the physics of dielectrics.
The total number of publications is over 800, including 14 monographs, over 250 publications in English, including 38 articles in influential foreign journals with a high impact factor. The total number of publications by the members of the scientific school registered in the SCOPUS database is 94, the number of citations of these scientific articles is 446, the Hirsh index of Prof. S.N. Fedosov (11) is the highest among all the teachers of ONAFT. Prof. A.E.Sergeeva occupies the 6th place among all ONAFT lecturers by the number of articles in the Scopus and the index of citation (5). These important indicators are better not only in ONAFT, but also in comparison with some institutes of the National Academy of Sciences of Ukraine.
The list of the most significant foreign internships and scholarly assignments includes 34 items, including work at UNESCO, 15 missions to serve as guest professors, NATO internships, and numerous presentations at international conferences abroad. 26 grants from international scientific foundations have been received testifying the international recognition of the scientific school and its high authority. Actual members of the scientific school during their existence have prepared 2 DSc and 12 PhD dissertations. There is a cooperation with 12 scientific centers, including 9 scientific centers abroad.
2. Scientific direction: “Physics of phase transitions and critical phenomena in heterogeneous systems” under the direction of Prof. V.B. Rogankov. The main goal of many years of scientific research is the development of new materials of electronic technology with ion conductivity and technologies for their obtaining; the study of physical and chemical properties of thin films of superionic conductors and the development of oxygen sensors, halogens, ammonia and freons.
At this time, the theory of phase transitions and critical phenomena in complex thermodynamic systems has been successfully developed. Investigation of phase transitions and transformations in solutions, the basic component of which is one or several molten organic salts, called ionic liquids, is a relatively new but very promising area of research, including the development of modern high technology. In particular, such important application problems as the transformation of solar energy into forms of thermal and electric with the associated search for new methods for efficient heat transfer and the accumulation of solar energy can be solved with ionic liquid solutions, as it is planned to justify as a result of research.
Within the framework of theoretical studies, the intensity of absorption of solar energy in nanotubes and the thermophysical properties of nanotubes are studied. The use of new nanotubes will contribute to a significant increase in the efficiency of conversion of energy in solar installations.
An evidence of recognition of the scientific achievements of Prof. V.B. Rogankov and his followers is active cooperation with such well-known scientists as Prof. M. Fischer and Prof. M.A. Anisimov (University of Maryland, USA), Prof. G. Smith (University of Salt Lake City, USA), Prof. J. Schmelzer (University of Bochum, Germany), cooperation with other universities, in particular in Hungary.
21 articles of Prof. V.B. Rogankov are registered in the scientific Scopus base and 67 foreign scientists made references to his works. The index of citation of his articles (6) is one of the highest among the teachers of ONAFT.
In recent years, 2 grants have been received from the Ministry of Education and Science of Ukraine, in which fundamental research of the heterogeneous structure of the fluctuations in the concentration of binary systems of ion liquid (IR) -water in the bulk phases and porous matrices are carried out. The project aims to significantly improve the existing technologies for use and conservation of the thermal energy through the development of new heat storage batteries and the development of new coolants based on IP solutions, as well as the creation and justification for the use of a new generation of advanced heat carrier, namely IP. The basic model of fluctuation thermodynamics is described and illustrated by the corresponding data for pure IPs. The results of the research are presented in a monograph printed in English by V.B.Ronkanov “Fluctuation Equation of the State and the Hypothetical Phase Diagram”. – (LAP Lambert Acad Publ., Saarbrucken, Germany, 2016 – 264 pages.
The impossibility of purely experimental solution of the problem was fully justified, both from physico-chemical and economic points of view. The next steps provide for the creation of a new substantiated methodology for predicting the properties of pure IPs and their solutions in the field of phase transitions.
3. Scientific direction “Investigation of thin vacuum polymeric films and coatings of functional purpose”, scientific supervisor – Doctor of Chemical Sciences, Prof. V.G. Zadorozhniy. The development of technology for vacuum polymeric films and coatings was implemented at the Research Institute of Optical and Physical Measurements, at the State Optical Institute, at the Radio Engineering Institute, at the Odontology Clinic at the Odessa National Medical University.
4. Scientific direction “Improving the productivity of profile grinding on CNC machines on the basis of adaptation of elements of the technological system” in recent years was developed by Associate Professor N.V. Lischenko, who in 2018 successfully defended her doctoral dissertation on this topic and received a doctoral degree in technical sciences. The results of scientific developments have been implemented into the industry. The testing and adjustment of diagnostic devices and adaptive control systems (SAUs) were performed on grinding and cutting processes on CNC machine tools or machining centers (OCs). Optimized processes and technological systems of diamond-abrasive and blade processing and methods of technological diagnostics and adaptive control of machine tools according to physical parameters of processes were developed. Works were carried out in cooperation with Bauman MGTU and Ufa State Aviation Technical University.
