Chemical shifts of atomic core levels and structure of K1−xTi1−xSbxOPO4, x=0–0.23, solid solutions
Victor V. Atuchin,Olga A. Alekseeva,V.G. Kesler,L.D. Pokrovsky,Nataliya I. Sorokina,V. I. Voronkova +5 more
TL;DR: In this paper, the binding energy difference Δ(O 1s−Ti 2p3/2) correlates with the shortening of mean oxide bond length at x = 0.23 that suggests increased ionicity of Ti−O bonds in K 1−xTi1−xSbxOPO4 solid solutions.
Journal ArticleDOI
Crystal structure of the oxygen conducting compound Nd5Mo3O16
Olga A. Alekseeva,A. Gagor,Adam Pietraszko,Nataliya I. Sorokina,Nadezhda B. Bolotina,Vladimir V. Artemov,Elena P. Kharitonova,V. I. Voronkova +7 more
TL;DR: In this article, the structure of the Nd5Mo3O16 single crystal was studied using the X-rays diffraction technique at 293 K and 110 K temperatures and the unit-cell values were always cubic relating to that of CaF2 fluorite as a ≈ 2af (af = 5.5
Journal ArticleDOI
Structural and Thermal Properties of Montmorillonite/Ionic Liquid Composites
Olga A. Alekseeva,Andrew V. Noskov,E. V. Grishina,L. M. Ramenskaya,N.O. Kudryakova,Vladimir Ivanov,Vladimir Ivanov,Alexander V. Agafonov +7 more
TL;DR: The highly developed surface of montmorillonite K10, obtained by acid treatment, plays a major role in the decrease in the IL’s thermal stability, and it has been revealed that when IL is adsorbed on the surface of clay, the phase transitions in IL change.
Journal ArticleDOI
Investigation of the Structure of Crystal-Forming Solutions of Potassium Dihydrogen Phosphate K(H 2 PO 4 ) (KDP type) on the Basis of Modeling Precursor Clusters and According to Small-Angle X-Ray Scattering Data
Mikhail V. Kovalchuk,Mikhail V. Kovalchuk,Mikhail V. Kovalchuk,Olga A. Alekseeva,A. E. Blagov,A. E. Blagov,G. D. Ilyushin,K. B. Il’ina,K. B. Il’ina,Petr V. Konarev,Petr V. Konarev,V. A. Lomonov,Yu. V. Pisarevsky,Yu. V. Pisarevsky,Georgy S. Peters +14 more
TL;DR: In this paper, the authors investigated the self-assembly of supramolecular KDP structures and determined oligomer clusters (dimers, tetramers, and octamers) in a supersaturated solution in a wide temperature range.
Journal ArticleDOI
Low-temperature structural and magnetic phase transitions in multiferroic GdFe3(BO3)4
K. V. Frolov,Igor S. Lyubutin,Ekaterina Smirnova,Olga A. Alekseeva,I. A. Verin,Vladimir V. Artemov,S. A. Kharlamova,L. N. Bezmaternykh,I. A. Gudim +8 more
TL;DR: In this paper, the dynamics of spin reorientation in sublattices Fe1 and Fe2 were studied in detail, and it was shown that the volume of the crystal decreases uniformly in the direction of all three axes at 155-80 K.
