Yaroslav Kravchenko is a senior lecturer and research associate at the Department of Nanoelectronics and Surface Modification at Sumy State University. In 2020, he defended his doctoral dissertation in solid-state physics. Y.K.'s research activities are focused on the development and design of nitride and intermetallic nanolaminates, two-dimensional materials, and biodegradable polymers for 3D printing. His scientific research has been supported by a scholarship under the Erasmus Mundus Eminence program, two small grants from the non-governmental fund Biotech Initiative US-Ukraine, as well as an individual postdoctoral grant from the project "OPUS" (National Scientific Center of Poland).
Among his achievements, he received the Young Scientists Award from the National Academy of Sciences of Ukraine in 2021 and the title of Best Young Scientist at Sumy State University in 2023 in the field of Mathematical Sciences and Natural Sciences. According to the Scopus database, the h-index is 13, and the total number of citations is 443. After obtaining the PhD degree, his scientific activities have taken on an interdisciplinary nature. All recent research is closely related to biomedicine and aims to integrate knowledge from solid-state physics into biomedical developments. Plans for the future include the introduction of current developments into clinical practice, the strengthening of our own scientific group and the strengthening of international relations.
Hybrid Nitride Nanolaminates Functionalized using MXene Nanosheets for Biomedical Implants
The development of new materials and technological solutions for surface modification of orthopedic structures, such as implants, plates for osteosynthesis, remains an urgent task due to the increase number of surgical interventions for the treatment of degenerative diseases, combat injuries and the consequences of car accidents. The main goal of the project is the development of multilayered hybrid nanocomposite for implant surface modification using PVD synthesis methods and their subsequent biofunctionalization using MXene. Nanolaminates Me1-x/MeN and Me1-xN/MeN based on tantalum and niobium with different modulation periods and combinations of alloying elements will be synthesized on the surface of planar products and implants of complex geometry. Hybridization of coatings or imparting antibacterial properties will be realized through MXenes, which can create a direct physical effect on the cell wall of microorganisms and be uniformly firmly fixed on the surface of nanolaminates. The hypothesis of the project is based on the assertion that the synthesis of coatings with nanolaminate Me1,2/MeN and Me1,2N/MeN architecture based on metallic materials with the necessary high biocompatibility and electrochemical stability, such as Ta, Nb, Cu, will improve corrosion resistance, abrasion resistance surface, prevent the leaching of metal ions from the base material of the implant and stimulate the osseointegration of implants due to uneven surface morphology.
