Слайди презентації

Fundamental physics and mathematics principles of complex wave structures needed for research and development of complex crystal-like structures and signal processing devices based on them were created. The generalized impedance model of different wave nature barrier structures is developed. In the analysis of structures impedance model allows use of the nonuniform transmission lines theory.

Fundamentals of design and creation of heteroepitaxial structures of perovskite materials for instrument

The dependence of the concentration of lead and calcium Raman spectra (RS) films of lead titanate-calcium Pb1-xCaxTiO3 (PCT), it is determined that the substitution of Pb Ca on the general nature of the spectra does not change even when x = 0.45 Raman spectra correspond to tetragonal ferroelectric phase, which is implemented in pure PCT. It was revealed that the soft mode component A1(TO) in the film-lanthanum titanate lead Pb0.9La0.1TiO3 (PLT) has a frequency of 280 cm-1 and significantly shifted to lower frequencies with an increase in the content of La.

Creation of theoretical principles of an integrated system of early diagnosis and prediction of the development of vibration disease symptoms

On the basis of technology TONTOR reasonably new principles of integrated combination of sensors BTO system that will allow not only the early detection of disease, but also carry out preventive measures to detect vibration characteristics.

Capacity SiO2/Al2O3-cathode of lithium power sources depending on the energy redistribution of the electrons caused by the conditions of synthesis of nanocomposites

Перенос електронів від металів в зв’язуючі і незв’язуючі  стани кисню та зниження зарядової ємності ЛДС при циклюванні

The charge capacity of cathodes of lithium power sources (LIPS) depends on the degree of implementation of the ions in the structural channels, defects and other features of the developed surface of nanosized materials. Interaction ions of lithium with the ions which are on the surface nanoparticles directly dependent on the energy distribution of the valence electrons, particularly a negatively-charged ions. It is important to identify change of these characteristics as a result of methods of synthesis of nano-sized composites.

Scientific principles, methods and techniques to reduce the impact of low-frequency oscillations in the power modes of the United Power System

Analysis of accidents in electric power systems (EPS) of the world has shown that one of the reasons for their occurrence is poor damped low-frequency oscillations (LFO). This requires solving of the complex problem aimed to reduce the LFO impact and increase the stability of the EPS. For the interconnected power system (IPS) of Ukraine, which is characterized by relatively weak interconnections in the conditions of rising of amount of distributed energy sources (RES) to solve these problems it is particularly important.
