Distribution of cobalt Co2+ ions in single crystals of spinel Li0.5Ga2.5O4 / V. V. Shapovalov, V. A. Shapovalov, T. V. Drokina [et al.] // Phys. Met. Metallogr. - 2024. - Vol. 125, Is. 1. - P. 27-32, DOI 10.1134/S0031918X23602883. - Cited References: 22 . - ISSN 0031-918X. - ISSN 1555-6190

electron paramagnetic resonance -- spinel single crystal -- unit cell -- crystal lattice -- structurally nonequivalent positions of ions
Аннотация: The distribution of Co2+ ions over sublattices and structurally nonequivalent positions in the unit cell of the crystal lattice of a single crystal of lithium gallium spinel Li0.5Ga2.5O4 is shown. This distribution determines the properties of both mono- and nanocrystalline substances. The distribution is obtained by a special technology and is manifested in the electron paramagnetic resonance (EPR) spectra. The distribution of Co2+ ions depends on the structural and magnetic nonequivalence. The structural and magnetic nonequivalence causes a multiminimum behavior of the crystal field potential in the unit cells of single crystals at the locations of Co2+ ions. The Co2+ ions are found in complexes with tetrahedral and octahedral oxygen ions. Three types of EPR spectra of Co2+ ions have been found and investigated. The Cotetr2+ spectrum is attributed to the Co2+ ion, which replaces the Ga3+ ion located in a tetrahedral oxygen environment. The spectrum of the Cooct2+ ion located in the crystal field with axial symmetry belongs to the Co2+ ion replacing the Li+ ion located in an octahedral oxygen environment. The spectrum of the Cooct2+ ion located in a low symmetry crystal field belongs to the Co2+ ion replacing the Ga3+ ion located in an octahedral oxygen environment. The nearest cationic environment of the ion creates rhombic distortions due to the different valence numbers of Li+ and Ga3+. The results of studying the angular dependences of the spectra show the presence of four and twelve magnetically nonequivalent positions in the unit cells.

Biodegradable polyhydroxyalkanoates formed by 3- and 4-hydroxybutyrate monomers to produce nanomembranes suitable for drug delivery and cell culture / T. G. Volova, A. V. Demidenko, A. V.

degradable polyhydroxyalkanoates -- copolymers P(3HB-co-4HB) -- electrostatic molding -- membranes -- microstructure and properties -- drugs -- release kinetics -- antibacterial activity -- fibroblast proliferation
Аннотация: Biodegradable polyhydroxyalkanoates, biopolymers of microbiological origin, formed by 3- and 4-hydroxybutyrate monomers P(3HB-co-4HB), were used to obtain nanomembranes loaded with drugs as cell carriers by electrospinning. Resorbable non-woven membranes from P(3HB-co-4HB) loaded with ceftazidime, doripinem, and actovegin have been obtained. The loading of membranes with drugs differently affected the size of fibers and the structure of membranes, and in all cases increased the hydrophilicity of the surface. The release of drugs in vitro was gradual, which corresponded to the Higuchi and Korsmeyer-Peppas models. Antibiotic-loaded membranes showed antibacterial activity against S. aureus and E. coli, in which growth inhibition zones were 41.7 ± 1.1 and 38.6 ± 1.7 mm for ceftazidime and doripinem, respectively. The study of the biological activity of membranes in the NIH 3T3 mouse fibroblast culture based on the results of DAPI and FITC staining of cells, as well as the MTT test, did not reveal a negative effect despite the presence of antibiotics in them. Samples containing actovegin exhibit a stimulating effect on fibroblasts. Biodegradable polyhydroxyalkanoates formed by 3-hydroxybutyrate and 4-hydroxybutyrate monomers provide electrospinning non-woven membranes suitable for long-term delivery of drugs and cultivation of eukaryotic cells, and are promising for the treatment of wound defects complicated by infection.

magnetic nanoparticle -- malignant cell membrane -- apoptosis -- anticancer therapy -- aptamer
Аннотация: The paper discusses schemes for the implementation of magneto-mechanical anticancer therapy and the most probable scenarios of damaging mechanical eﬀects on the membranes of malignant cells by targeted magnetic nanoparticles selectively bound to membrane mechanoreceptors employing aptamers. The conditions for selective triggering of the malignant cell apoptosis in a low-frequency non-heating alternating magnetic ﬁeld, corresponding to the exceeding threshold value of the force acting on the membrane and its mechanoreceptors, are established using a nanoparticle dynamic simulation. The requirements for the functionality of magnetic nanoparticles and their suitability for biomedical applications are analysed. Attention is paid to the possibility of the formation of magnetite nanoparticle aggregates in an external magnetic ﬁeld and their localization near tumor cell membranes. It is shown that the scenario involving the process of aggregation of magnetite nanoparticles provides a suﬃcient magneto-mechanical impact to achieve a therapeutic eﬀect. A possible explanation for the experimentally established fact of successful application of magneto-mechanical therapy using magnetite nanoparticles is presented, in which complete suppression of the Ehrlich carcinoma in an alternating magnetic ﬁeld as a response to a magnetome-chanical stimulus was demonstrated. This result conﬁrmed the possibility of using the method for high eﬃciency treatment of malignant neoplasms. The paper is provided with an extensive review of key publications and the state of art in this area.

Кл.слова (ненормированные):
magnetite nanoparticles -- adsorption -- organic dyes -- aptamers -- magnetically induced cell destruction
Аннотация: The morphology, structure, and magnetic properties of Fe3O4 and Fe3O4@C nanoparticles, as well their effectiveness for organic dye adsorption and targeted destruction of carcinoma cells, were studied. The nanoparticles exhibited a high magnetic saturation value (79.4 and 63.8 emu/g, correspondingly) to facilitate magnetic separation. It has been shown that surface properties play a key role in the adsorption process. Both types of organic dyes—cationic (Rhodomine C) and anionic (Congo Red and Eosine)—were well adsorbed by the Fe3O4 nanoparticles’ surface, and the adsorption process was described by the polymolecular adsorption model with a maximum adsorption capacity of 58, 22, and 14 mg/g for Congo Red, Eosine, and Rhodomine C, correspondingly. In this case, the kinetic data were described well by the pseudo-first-order model. Carbon-coated particles selectively adsorbed only cationic dyes, and the adsorption process for Methylene Blue was described by the Freundlich model, with a maximum adsorption capacity of 14 mg/g. For the case of Rhodomine C, the adsorption isotherm has a polymolecular character with a maximum adsorption capacity of 34 mg/g. To realize the targeted destruction of the carcinoma cells, the Fe3O4@C nanoparticles were functionalized with aptamers, and an experiment on the Ehrlich ascetic carcinoma cells’ destruction was carried out successively using a low-frequency alternating magnetic field. The number of cells destroyed as a result of their interaction with Fe3O4@C nanoparticles in an alternating magnetic field was 27%, compared with the number of naturally dead control cells of 6%.

Complete light polarization control using a chiral-nematic cell with tangential-conical boundary conditions / A. S. Abdullaev, D. A. Kostikov, M. N. Krakhalev, V. Y. Zyryanov // Opt. Mater. - 2023. - Vol. 146. - Ст. 114521, DOI 10.1016/j.optmat.2023.114521. - Cited References: 20 . - ISSN 0925-3467. - ISSN 1873-1252
Кл.слова (ненормированные):
Light polarization -- Chiral nematic -- Conical anchoring -- Orientational structure -- Photosensitive dopant -- Electric field
Аннотация: Light polarization control by the chiral-nematic cell with hybrid tangential-conical boundary conditions has been studied by means of photo- and electrically induced transformations of the orientational structure. The polarization azimuth changes due to the power ratio of ultraviolet and blue radiations, at which the director twist angle in the chiral nematic varies smoothly. The light polarization ellipticity is controlled by an electric field applied perpendicular to the liquid crystal cell changing the effective anisotropy of the refractive index. The optical material under study is promising to develop the devices for the light polarization converter over the entire visible range, as well as for photo-controlled rotators of linear polarization of white light.

Аннотация: Neodymium iron borate NdFe3(BO3)4 is an intensively studied multiferroic with high electric polarization values controlled by a magnetic field. It is characterized by a large quadratic magnetoelectric effect, rigidity in the base plane and a rather strong piezoelectric effect. In this work, the atomic structure of (Nd0.91Bi0.09)Fe3(BO3)4 was studied by single-crystal X-ray diffraction in the temperature range 20–500 K (space group R32, Z = 3). The Bi atoms found in the composition partially substitute the Nd atoms in the 3a position; they entered the structure due to the growth conditions in the presence of Bi2Mo3O12. It was shown that in the temperature range 20–500 K there is no structural phase transition R32→P3121, which occurs in rare-earth iron borates (RE = Eu–Er, Y) with an effective rare-earth cation radius smaller than that of Nd. The temperature dependence of the unit-cell c parameter reveals a slight increase on cooling below 90 K, which is similar to the results obtained previously for iron borates of Gd, Y and Ho. The atomic distances (Nd,Bi)—O, (Nd,Bi)—B, (Nd,Bi)—Fe, Fe—O, Fe—B and Fe—Fe in the iron chains and between chains decrease steadily with decreasing temperature from 500 to 90 K, whereas the B1(3b)—O distance does not change and the average B2(9e)—O distance increases slightly. There is a uniform decrease in the atomic displacement parameters with decreasing temperature, with a more pronounced decrease for the Nd(3a) and O2(9e) atoms. The O2(9e) atoms are characterized by the maximum atomic displacement parameters and the most elongated atomic displacement ellipsoids. The characteristic Debye and Einstein temperatures, and the static component in the atomic displacements were determined for cations using multi-temperature diffraction data. It was shown that the Nd cations have the weakest bonds with the surrounding atoms and the B cations have the strongest.

Аннотация: Форма многоминимумного потенциала электрического кристаллического поля в нанокомплексе с магнитным ионом формируется ближайшим окружением иона и имеет несколько эквивалентных минимумов, которые соответствуют кристаллографическим осям комплекса. Для описания спектров электронного парамагнитного резонанса (ЭПР) магнитных ионов используется модель кристаллического поля и формализм спинового гамильтониана. Метод спинового гамильтониана позволяет описать спектр электронного парамагнитного резонанса. Задача теории - получение констант на основе определенной модели кристалла. Задача эксперимента - определение этих констант из вида спектра.
The form of a multi-minimum potential of the electrical crystal field in a nanocomplex with a magnetic ion is formed by the nearest environment of the ion and characterized by several equivalent minima that are associated with crystallographic axes of the complex. To describe the spectra of electron paramagnetic resonance of magnetic ions (EPR), the model of crystal and the formalism of spin Hamiltonian is used. The method of spin Hamiltonian allows description of the spectrum of electron paramagnetic resonance. The theory is aimed to calculation of the constants within the frameworks of the determined model of the crystal. The experiment goal is evaluation of these constants on the basis of the spectrum shape.

Аннотация: A liquid crystal cell is used to produce correlated light beams with speckle structures for implementation of pseudo-thermal ghost imaging. The liquid crystal cell makes it possible to provide random spatial intensity distributions, which are characterized by a low coefficient of mutual cross correlations. Ghost imaging of an object representing an amplitude mask is demonstrated. The quality of the reconstructed images was estimated by the method of structural similarity.
