Opis:: Synthesis conditions influence on structure of FexCoyOz - nanoparticle in SiO2 - sol-gel coating is discussed. The samples are synthesized by hybrid sol - gel method including following stages: TEOS hydrolysis, introduction into sol of Co(NO3)2 . 6H20 and Fe(NO3)3 . 9H20, deposition of film-forming sol by spin-coating on silica substrate, heat treatment at the temperature from 200 up to 900 °C. The Synthesis conditions influence on a specific structural property of sol gel films is investigated by AFM.

Opis:: A development of high-performance materials for electronics, optics, ceramics fabrication is restrained by traditional modes of their production. Basic technologies for materials include high-temperature physical and chemical processes and require special conditions to attain desired properties of final products. Advanced preparation methods for materials with new features are feasible on the basis of colloid-chemical processes and nanochemistry. In this respect the sol-to-gel transformation followed by solidification and chemical modification are of great interest to attain a variety of different functional properties of materials.

Opis:: Usage of the distributed information databases (DIDB) is the most spread way of allocation of service of clients and support of cooperation between large corporations or banks. At usage DIDB in real-time mode (the actual data are accessible to all valid users at the moment of inquiry to reading or upgrade) most essential is the factor of capacity of networks. Change of the physical characteristics of modern networks is very expensive procedure. Moreover, if a gorge by transmission becomes data links, their replacement also requires essential time, that can reduce in the additional losses. In such conditions the mechanism of backup is applied to support of continuity of the computing process (CP). Except for data links a gorge in operation with DIDB can be intermediate sites, gateway servers, routers and other equipment. Frequently these functions can fulfil the same computational capabilities, which are used for processing DIDB. In this case (if the backup is not stipulated by network architecture) it is necessary to reallocate a working load (WL) between other network nodes on time of exception of a site for realization of adaptive operations or its replacement.

Opis:: The corrosion action for bulk and thin Nd₂Fe₁₄B films magnets in different corrosion media was studied. The thin Nd-Fe-B films of 100 nm ≤ d ≤ 1000 nm were deposited on glass substrate by "flash" evaporation method. The structure and microstructure of the samples were studied by X-ray diffraction analysis, scanning electron microscopy. The temperature dependence of the magnetization before and after corrosion action was carried out by ponderomotive method in the temperature range 80 ≤ T ≤ 800 K. It is shown that the specific magnetizations of the thin Nd-Fe-B films with d ≥ 1000 nm are comparable to those measured for the powder samples. The values of the coercive and saturation fields were determined from the hysteresis loops measurements.

Opis:: The synthesis of polycrystalline $Mn_{1-x}Gd_{x}Se$ solid solutions is carried out by solid state reaction method followed by quenching from the temperature of 1370 K. The X-ray diffraction studies realized at 300 K revealed that the structure of the single phase samples in the 0 < x < 0.15 concentration range is identified on base a face centered cubic crystal cell of Fm3m space group. The heating of the solid solutions to 900 K does not affect on the magnetic susceptibility as the dependences is identical to the measurements in the "heating-cooling" regime. Comparing the research results of magnetic properties of the $Mn_{1-x}Gd_{x}Se$ solid solutions with those of $Mn_{1-x}Gd_{x}S$ solid solutions, we can conclude that substitution of manganese ions by gadolinium in manganese selenide lead to more changes in the basic magnetic characteristics than in manganese sulfide.
