Exploring RF Magnetron Sputtering Growth Composite Thin Film BiFeO-BiFeO on C-Plane AlO Substrate.

Nanocomposite films of BiFeO-BiFeO were fabricated on a sapphire substrate AlO using the method of gas discharge high-frequency cathodic sputtering of a ceramic target with a stoichiometric composition in an oxygen atmosphere. The results of the film analysis using X-ray structural analysis, Raman scattering, XPS, and atomic force microscopy are presented. The lattice parameters, surface topography, chemical composition of the films, concentration, and average sizes of the crystallites for each phase were determined.

Research of the structure and dynamic interactions of particles in the LiKNO- R (R = α-AlO, γ-AlO, SiO) and (LiNO-LiClO) - γ-AlO composites in various temperature conditions and phase states.

The paper presents a comprehensive study of the LiKNO- R (R = α-AlO, γ-AlO, SiO) and (LiNO - LiClO4) - γ- AlO composite salt systems by vibrational spectroscopy, X-ray diffractometry, and differential scanning calorimetry. According to the results of Raman spectra and XRD analysis, it has been found that in the case of a sufficiently small filler (15 nm-γ-AlO and SiO), an amorphous phase appears, both for systems based on LiKNO and for the nanocomposite based on (LiNO)-(LiClO). In the case of nanocomposites based on the LiKNO system, this additionally leads to the formation of the metastable KNO (R3m) phase.

Self-association and picosecond dynamics in liquid dimethyl sulfoxide.

Dimethyl sulfoxide (DMSO) has been known for almost 150 years, but its properties as a solvent and reaction medium are far from being understood. In particular, association equilibriums in liquid DMSO have been characterized in just four papers, and the enthalpy of its self-association is unknown. The aims of this paper are to study self-association equilibriums in neat liquid DMSO at various temperatures by means of Raman spectroscopy, to find the enthalpy of self-association, and to solve the problem of hydrogen bonding in this liquid.

The peculiarities of spectral manifestations of high-voltage electric discharge in different phase states of ion systems.

The effects of high-voltage pulsed discharge (HVPD activation) on vibrational spectra of ion salt systems have been studied. The peculiarities of spectral display of HVPD in ion melts and aqueous solutions of electrolytes, in ion-conducting phases of crystalline and glassy salt systems have been investigated. After HVPD a salt system is in non-equilibrium activated state.

[Surgical treatment of decompensated craniostenosis].

The work is based on the analysis of 148 patients with decompensated craniostenosis who underwent operation at the neurosurgical clinic of Oran (the Algerian People's Democratic Republic). The specific features of the clinical manifestations of decompensated craniostenosis are discussed. Sixty-five patients were operated on by the method suggested by V.
