Заглавие документа: Molecular Mechanics Methods of Carbon Nanotubes Vibration Spectra with and without Molecules Incorporation Авторы: Pushkarchuk, A. L.; Khrutchinsky, A. A.; Kuten, S. A.; Pushkarchuk, V. A.; Nizovtsev, A. P.; Kilin, S. Ya.; Saad, A. M. Аннотация: This work explored the influence of molecules, incorporated in a single wall nanotube, on the nanotube vibration spectrum using the molecular mechanics methods. It has been shown that the main effect results in shifting the spectra towards a lower frequency region. The shift value is 5 - 10 % and depends on the molecule type incorporated in the nanotube. The shift increases as the number of incorporated molecules increases but this shift is not linearly proportional to this number.

Заглавие документа: Two-Dimensional Oscillations in a Quantum Well with Polynomial Potential Авторы: Sanin, А.; Semyonov, Е. Аннотация: Numerical integration of the non-stationary Schrödinger equation with polynomial potential depending on two coordinates has been carried out. The oscillation types and the influence of coupling between two degrees of freedom on the tunneling and the frequency spectra are analyzed in detail.

Заглавие документа: Fiber-Optic Fluorescence Temperature Sensors Авторы: Khodasevich, Mikhail; Sinitsyn, George; Varaksa, Yury Аннотация: Fluorescence intensity ratio (FIR) sensors are a promising type of fiber-optic temperature sensors that are based on measurement of fluorescence intensity ratio from two temperature-coupled energy levels. We study transparent lead-fluoride glass-based nano-glass-ceramics as a sensing element of FIR sensors. Such media combine positive properties of both glass host and doped nanocrystals. On the basis of a theoretical model of a FIR sensor developed the modeling of the sensor is performed taking noises into account. It is planned to perform optimization of dopant ions concentration and secondary heat treatment regimes as well as to determine ultimate accuracy of temperature measurement by FIR sensors.

Заглавие документа: The Influence of the Nano-Size Fullerides C60(FeCp2)2, C60(NiCp2)2 and its Derivatives on the Cell Proliferation in Vitro Авторы: Soldatov, Andrei G.; Shpilevski, Edward M.; Goranov, Vitalii A.; Potkin, Vladimir I.; Shirokii, Valerii L.; Pushkarchuk, Alexander L.; Tuna, Floriana Аннотация: In this work we studied structural, magnetic, optical and some other proprieties of fullerides C60(FeCp2)2, C60(NiCp2)2 and their derivatives. The influence of fulleride particles on the cell proliferative activity was also investigated. We found that the proliferative activity of the RINmF5 cells increases (53 % vs. control) in the presence of C60(FeCp2)2 nano-size particles. Moreover it was registered that the cell culture becomes multi-layered and secreted basophile matrix. We also present the results of quantum chemical studies of C60(FeCp2)2 complex. It was shown in particular that the spin density is localized on the atoms C belonging to the fullerene molecule.
