This review is devoted to the synthesis of palladium heterogeneous catalysts on carbon supports. The review consists of three parts. In the first part different types of carbon supports are explored. The second part is devoted to methods of activation of carbon supports, and in the third part methods of preparation of palladium catalysts supported on carbon are investigated.

The synthesis and data of the study of new complexes of samarium bromides with carbamide, [Sm(Ur)4(H2O)4]Br3 (I) and [Sm(Ur)6(H2O)2]Br3 (II), by IR spectroscopy and X-ray diffraction analysis are presented. For these compounds, coordination with the metal occurs through the oxygen atoms of the water and carbamide molecules. The coordination polyhedra are distorted tetragonal antiprisms. The coordination of four carbamide molecules in I does not change their planar structures, but in II one carbamide ligand is distorted. The bromide ions are not coordinated and are situated in the external sphere. Many hydrogen bonds are observed in the structures of both complexes. Ключевые слова: комплексные соединения, самарий, бромид, карбамид, строение. Key words: complexes, structure, carbamide, samarium, bromide.

The article is devoted to the determination of the perrhenate anion in real in-situ leaching solutions by means of voltammetry on the interface between two immiscible electrolyte solutions and a mass-produced voltammetric ion-selective electrode. Methods of overcoming the interfering influence of different factors, e.g., high amounts of molybdenum, low pH and high concentration of iron, are also discussed. On the basis of this study a method for the determination of rhenium concentration in real industrial solutions was developed and certified.

Comparison of literature and calculated data on vapor-liquid equilibrium for systems formed by products of propylene oxide synthesis was carried out. On the basis of models NRTL and UNIQUAC the literature data on vapor-liquid equilibrium for the investigated systems were optimized. The values of model parameters and their deviations were estimated. The corresponding phase diagrams were calculated and plotted.

The theoretical analysis of process of unitary recrystallization of substances from solutions with separate supply of binary solvent components on a stage of dissolution of initial substance and the subsequent stage of crystallization is carried out. The theoretical description is based on consideration of the equations of material and thermal balances taking into account phase equilibrium. Influence of various parameters on yield of products of division and power expenses is established.

Magnetic nanoparticles (MNPs) obtained by two methods - thermal decomposition of iron(V) pentacarbonyl and polyol synthesis - were characterized with the use of dynamic/electrophoretic light scattering and high resolution transmission electron microscopy. The obtained MNPs were tested as potential agents for magnetic hyperthermia by measuring their ability to cause water dispersion heating in an electromagnetic field.

Influence of prismatic cross-section rods surface quality on natural frequencies and mode shapes is investigated. Modified equations of Kirchhoff and Klebsh are used. These equations allow taking into account the influence of tension-compression and in-plane shear of rods. Linear initial-value boundary-value eigenvalue problem is formulated. Modeling of frequency function is carried out with the help of method of initial parameters. Existence of nonlinear dependence of natural frequencies on rod cross-section parameters changing and high sensitivity of mode shapes when changing rod cross-section parameters is confirmed, Urgency of developing special high-precision algorithms of ill-conditioned boundary problems solution for practical use of the confirmed effect is revealed.
