    Change in structural and potentiodynamic characteristics of SiO2/TiO2 nanocomposite due to changing mechanosynthesis duration
    (Igor Sikorsky Kyiv Polytechnic Institute, 2023) Tiancheng, An; Yavorskyi, Yurii
    Structure and scope of practice work. The paper consists of 6 chapters. literature review, research materials and methods, results, occupational health and safety in emergencies, economic section, development startup project, conclusions and reference list. This work include: 111 pages, 51 figures, 23 tables, 13 formulas, 58 references. Actuality. Modern technology requires the creation of new materials with the best electro-chemical and operational properties that meet the criteria of manufacturability, environmental friendliness, and low cost. Therefore, the study of the properties of materials with unique features is undoubtedly relevant. This work presents the study the of influence of the duration of mechanoactivation SiO2/TiO2 mixture with a component ratio of (80/20) % on the structure characteristics. The purpose and tasks of the research. The work aimed to determine the effect of the duration of mechanical processing on the structural characteristics of the powder SiO2/TiO2 nanocomposite and dependence between the changes in structure and electrochemical characteristics. The object of the study – 80 % SiO2/20 % TiO2 nanocomposite after different duration of treatment. The subject of research – X-Ray diffraction patterns, ultra soft X-ray emission specters (USXE) and potenciodynamic (PD) data. Methods of research – XRD, USXE spectroscopy, PD investigation. Scientific innovation. The renowned technique of shock-vibration processing enables the amalgamation of the distinctive characteristics of nano-powder materials. The pioneering aspect of this research lies in ascertaining the impact of mechanical activation on the crystal-structural parameters of the SiO2/TiO2 nanocomposite, and PD characteristics of lithium power sourses.
