Аннотация: INTAS (The International Association for the Promotion of Cooperation with Scientists from the New Independent States of the Former Soviet Union) — международная ассоциация по содействию сотрудничеству с учёными новых независимых государств бывшего Советского Союза. Некоммерческая организация, финансировалась главным образом из бюджета Европейского Союза. Являлась крупнейшим фондом, поддерживающим научное сотрудничество между учёными стран бывшего СССР и Европейского Союза с 1993 г. Программы INTAS охватывали широкий круг научно-исследовательских проблем. 22 сентября 2006 года было принято решение о прекращении осуществления программы на основании рекомендации Европейской Комиссии. С 1 апреля 2007 года прекратилось распределение новых грантов.

Аннотация: Based on the results of in situ electron diffraction study of the solid-state reaction and electrical resistivity measurements on the Al/Ag thin films with an atomic ratio of Al : Ag = 1 : 3, the temperature of the reaction onset has been established and a model of the structural phase transitions has been proposed. The solid-state reaction begins at 70°C with the formation of the Al–Ag solid solution at the interface between the aluminum and silver nanolayers. It has been found that, in the course of the reaction, the intermetallic compounds γ-Ag2Al → μ-Ag3Al are successively formed. It is shown that the possibility of the formation of the μ‑Ag3Al phase during the solid-state reaction in the Al/Ag thin films depends on the aluminum-to-silver ratio, while the formation of the μ-Ag3Al phase begins only after all fcc aluminum has reacted.

Заглавие : In situ electron microscopy investigations of solid-state synthesis in Al/Au thin bilayer films
Место публикации : Bull. Russ. Acad. Sci.: Phys.: MAIK Nauka-Interperiodica / Springer, 2013. - Vol. 77, Is. 8. - P.1004-1007. - DOI 10.3103/S1062873813080042
Аннотация: In situ transmission electron microscopy investigations of solid-state synthesis in Al/Au thin bilayer films are conducted. The samples are heated in the column of a transmission electron microscope. The heating temperature is changed from room temperature to 300°C with a heating rate of up to 120°C min−1. It is found that solid-phase synthesis starts at ≈100°C. At 140 ± 5°C, two crystal phases, Al2Au (Fm3m) and AlAu2 (I4/mmm), are simultaneously observed, while at 235 ± 5°C and higher (up to 300°C) only Al2Au phase is detected.

Аннотация: The processes of phase formation during a solid-state reaction between Fe and Al nanolayers have been investigated by the in situ electron diffraction method. It is established that the solid-state reaction at the interface between iron and aluminum nanolayers begins at ≈100°C with the formation of a disordered Al solid solution in α-Fe. It is shown that intermetallic phases (FeAl6 and/or Fe2Al5, FeAl, and Fe3Al) are successively formed upon further heating.

Заглавие : Analysis of Ehrlich ascites carcinoma with electron paramagnetic resonance

Аннотация: The study was aimed to reveal the dependence of changes in the content of metal-containing proteins and freeradical forms in a suspension of the experimental tumor in different periods of tumor growth using electron paramagnetic resonance. The object of the study was Ehrlich's ascites carcinoma, an experimental undifferentiated tumor, which is used to study various aspects of tumor development under external influences. Ehrlich ascites carcinoma was inoculated into the peritoneal cavity of laboratory mice. We believe that the determination of the concentrations of metal-containing proteins and free-radical forms using this method may be an important prognostic parameter for assessing the state of the tumor. Changes in metabolism will inevitably affect the functionality of cells and, as a consequence, the dynamics of tumor growth. The results of the study showed that metalcontaining proteins belonging to ascites plasma, such as transferrin, ferritin and ceruloplasmin, do not undergo significant changes. The signal from molybdenum-containing proteins also does not change at the stages of experimental tumor growth under consideration. However, in the course of this experiment, it was possible to record a slight decrease in the intensity of the formation of denitrosyl iron complexes with the development of a tumor in the body.

Аннотация: A many-electron model of the energy band structure of VBO3 and of Fe1 - xVxBO3 solid solutions is proposed with strong electron correlations taken into account. Experimental optical absorption spectra and data on the resistivity are discussed in the framework of the suggested model. Variation in the magnetic and electronic properties of VBO3 and Fe1 - xVxBO3 under high pressure is predicted. For VBO3, a Mott-Hubbard (insulator-metal) transition is expected in the high-pressure phase. In Fe1 - xVxBO3 solid solutions, a nontrivial variation in the properties is predicted, leading to the appearance of a different magnetic state. (C) 2004 MAIK "Nauka / Interperiodica".

Ключевые слова (''Своб.индексиров.''): pmma opal--photonic crystal--electron microscopy--angular resolved reflective spectroscopy
Аннотация: PMMA opal crystal was prepared by a simple hybrid method, which includes sedimentation, meniscus formation and evaporation. We investigated three surfaces of this crystal by angle-resolved reflective light spectroscopy and SEM study. The angle-resolved reflective measurements were carried out in the 400–1100 nm range. We have determined the high-quality ordered surface of the crystal region. Narrow particle size distribution of the surface has been revealed. The average particle diameter obtained with SEM was nearly 361 nm. The most interesting result was that reflectivity of the surface turned out up to 98% at normal light incidence. Using a fit of dependences of the maximum reflectivity wavelength from an angle based on the Bragg–Snell law, the wavelength of maximum 0° reflectivity, the particle diameter and the fill factor have been determined. For the best surface maximum reflectivity wavelength of a 0° angle was estimated to be 869 nm. The particle diameter and fill factor were calculated as 372 nm and 0.8715, respectively. The diameter obtained by fitting is in excellent agreement with the particle diameter obtained with SEM. The reflectivity maximum is assumed to increase significantly when increasing the fill factor. We believe that using our simple approach to manufacture PMMA opal crystals will significantly increase the fabrication of high-quality photonic crystal templates and thin films
