Заглавие : Adaptation of a bacterial bioluminescent assay to monitor bioeffects of gold nanoparticles
Место публикации : Bioengineering. - 2022. - Vol. 9, Is. 2. - Ст.61. - ISSN 2306-5354(eISSN), DOI 10.3390/bioengineering9020061

Аннотация: Our current study aimed to adapt a bioluminescent bacteria-based bioassay to monitor the bioeffects of gold nanoparticles (AuNPs). Luminous marine bacteria Photobacterium phosphoreum and AuNPs modified with polyvinylpyrrolidone were employed; low-concentration (≤10−3 g/L) bioeffects of AuNPs were studied. Bioluminescence intensity was used as an indicator of physiological activity in bacteria. Two additional methods were used: reactive oxygen species (ROS) content was estimated with a chemiluminescent luminol method, and bacterial size was monitored using electron microscopy. The bacterial bioluminescent response to AuNPs corresponded to the “hormesis” model and involved time-dependent bioluminescence activation, as well as a pronounced increase in the number of enlarged bacteria. We found negative correlations between the time courses of bioluminescence and the ROS content in bacterial suspensions, demonstrating the relationship between bioluminescence activation and bacterial ROS consumption. The combined effects of AuNPs and a beta-emitting radionuclide, tritium, revealed suppression of bacterial bioluminescent activity (as compared to their individual effects) and a reduced percentage of enlarged bacteria. Therefore, we demonstrated that our bacteria-based bioluminescence assay is an appropriate tool to study the bioeffects of AuNPs; the bioeffects can be further classified within a unified framework for rapid bioassessment.

Заглавие : An update on inert anodes for aluminium electrolysis
Место публикации : Non-Ferrous Met. - 2020. - Vol. 48, Is. 1. - P.15-23. - ISSN 20720807 (ISSN), DOI 10.17580/nfm.2020.01.03

Аннотация: This update includes the literature related to the inert anodes which were published in the past decade. The metallic anodes are widely regarded as promising candidates to replace the carbon anodes due to its attractive properties like good electrical conductivity, easy to manufacture and high resistance to high thermal shocks. The metals have been tested in pure state and alloy (binary, ternary) form. The oxide scale formed on the anode surface acts as a barrier between the electrolyte and the anode, which protects the anode from being dissolved. The layer of molten fluorides is formed between the scale and the metal anode after a certain time of polarization, and the oxide scale acts as a bipolar electrode. Metal like Cu is reduced at the internal side of the scale. This paper elaborates the effects of various parameters on the performance of the anode. Cu-based alloys (Cu – Ni – Fe and Cu – Al) have shown promising results and could perform well in low-temperature electrolytes. It has been well established that the Cu content in Cu – Ni – Fe and Cu – Al alloys plays a major role in the metal dissolution as the CuO/Cu2O scales formed on the outer layer act as a sacrificial one. The corrosion rate of an anode can be reduced by decreasing the operating temperature, which is possible by using the KF – AlF3 melts. The use of suspensions can increase the purity of the produced metal by stop-ping the anode products to come in contact with cathode metal. Many industries including RUSAL and ELYSIS are still conducting a considerable amount of research to develop an inert anode and are expecting to have a carbon-free cell in the nearest future.

Ключевые слова (''Своб.индексиров.''): paleolimnology--diatom algae--meromictic lake--sedimentation--cyclotella choctawhatcheeana--aulacoseira valida--aulacoseira ambigua
Аннотация: Lake Shira as a meromictic lake is object of interest for paleolimnological studies. In May 2011 core samples were collected from the bottom of Lake Shira and the species composition of diatom algae, which serve as bioindicators of the state of the lake, were studied. In addition, in 2012, seasonal water samples and material from sediment traps were collected and the species composition of diatoms in them was analyzed. The results of the analysis showed that the lake, like in previous years of research, was dominated by Cyclotella choctawhatcheeana Prasad. Diatoms were found twice in the studied core above the white carbonate layers and were absent in other layers. The species living in the lake at present were observed down to the first white carbonate layer, including the predominant Cyclotella choctawhatcheeana. This fact presumably proves the consistency of the species composition of diatoms and the overall stable condition of the lake since 1946 (Rogozin et al., 2005). Down to the second white carbonate layer, the dominant species were Aulcosira valida (Grunow) Krammer and Aulcosira italica (Grunow) Simonsen. Nitzchia sigmodea (Nitzsch) W. Smith and Fragilaria construens var. venter (Ehrenberg) Grunow were also observed at these depths, dating approximately to 1655-1690. These are freshwater species that belong to the diatoms of arctic, alpine, and temperate latitudes, which develop in shallow waters under moderate temperature conditions. This fact suggests that Lake Shira was less salty in the middle and end of the 17th century than today.

Аннотация: It is shown that in the chloroplast periodic structure with a defect, the resonant absorption of light can be implemented. It is found that the resonant light absorption depends significantly on the position of a defect. In terms of the absorption of light energy, an asymmetric resonator is more efficient than a symmetric one.

Аннотация: The dynamics of the optical response of a polymer-dispersed nematic liquid crystal under the action of electric field pulses was experimentally studied for film samples differing in the size of nematic droplets. The optical signal relaxation curve exhibits an oscillating character, with the number of oscillations determined by the transverse size of the nematic droplets. The interference character of the signal oscillations is confirmed by an analysis of the oscillating response within the framework of the anomalous diffraction approximation and by a comparison with the dependence of the transmitted light intensity on the applied voltage measured in a static regime.

Заглавие : Biocompatible systems for controlled delivery of antiseptics for topical application
Колич.характеристики :14 с

Аннотация: Controlled drug delivery is one of the frontier areas of science, which uses an interdisciplinary approach. The delivery systems offer numerous advantages over conventional dosage forms, such as improved efficacy and patient compatibility, reduced toxicity, and ease of use. Such systems often use micro- and nanoparticles as carriers for drugs, the prolonged effect of which is achieved due to the controlled slow release of the encapsulated drug. This study investigated the effects of encapsulation of various antiseptics (brilliant green, miramistin, and furacilin) and the chemical composition of the polymer on the yield, structure, size, drug release kinetics, and antibacterial activity of microparticles produced from resorbable polyesters of microbiological origin, polyhydroxyalkanoates. Microparticles with a 5.6–94.8 μm diameter were produced. The form of the active substance molecule has been found to be the most significant factor affecting the characteristics of polyhydroxyalkanoate microparticles. The surface structure of particles is rather determined by the chemical composition of the polymer, and the release kinetics to the model medium depends on the encapsulated drug. Microparticles based on PHAs loaded with brilliant green and furacilin showed antibacterial effects in S. aureus and E. coli cultures. The study demonstrated that microparticles with antiseptics encapsulated in them have potential as prolonged drug delivery systems and are of interest for further research.Технология контролируемой доставки лекарств является одной из передовых областей науки, включающей междисциплинарный научный подход. Эти системы доставки обладают многочисленными преимуществами по сравнению с обычными лекарственными формами, такими как повышенная эффективность и биосовместимость, сниженная токсичность и простота использования. В таких системах в качестве носителей лекарственных средств часто используют микро- и наночастицы, пролонгированное действие которых достигается за счет контролируемого медленного высвобождения инкапсулированного лекарственного средства. В данном исследовании изучалось влияние включения различных антисептиков (бриллиантовый зелёный, мирамистин и фурацилин), а также химического состава полимера на выход, структуру, размер, кинетику высвобождения лекарственных средств и антибактериальную активность микрочастиц, полученных из резорбируемых полиэфиров микробиологического происхождения, полигидроксиалканоатов. Было получено семейство микрочастиц диаметром 5,6–94,8 мкм. Установлено, что наиболее значимым фактором, влияющим на характеристики микрочастиц полигидроксиалканоатов, является форма молекулы активного вещества. Структура поверхности частиц больше зависит от химического состава полимера, а кинетики выхода в модельную среду – от инкапсулированного лекарства. Микрочастицы на основе ПГА с депонированными бриллиантовым зеленым и фурацилином показали антибактериальное действие в культурах S. aureus и E. coli. Результаты продемонстрировали, что микрочастицы с депонированными антисептиками обладают потенциалом в качестве систем пролонгированной доставки и представляют интерес для дальнейших исследований.

Аннотация: Ceramic volumetric composites xLa(0.7)Pb(0.3)MnO(3)-(1-x)PbTiO3 (x = 0.18 and 0.85) were prepared. X-ray investigations have shown that rather low sintering temperature (800 degrees C) has allowed us to avoid the reaction and interdiffusion between two initial phases. Heat capacity, thermal expansion, and intensive magnetocaloric effect were measured in a wide temperature range. The sample composition has a low influence on temperatures of the ferromagnetic and ferroelectric phase transitions in composites. Electro- and barocaloric effects were determined by analysis in the framework of thermodynamic theory, electric equation of state, Maxwell relationships, and entropy-temperature-pressure phase diagram. Multicaloric efficiency of composites is discussed and compared with that of initial La0.7Pb0.3MnO3 and PbTiO3 compounds. Variation of a relationship between components can significantly increase both barocaloric and magnetocaloric efficiency of compositional material due to the mechanical stress appearing between grains of different ferroic phases under magnetic field.

Заглавие : Characteristics of the process of reorientation of bipolar drops of a nematic with rigidly fixed poles
Место публикации : JETP Letters. - 1998. - Vol. 67, Is. 9. - P.733-737. - ISSN 0021-3640, DOI 10.1134/1.567739

Аннотация: The director configuration in a bipolar drop of a nematic with rigidly fixed poles is calculated as a function of the electric field directed perpendicular to the symmetry axis of the drop. It is shown that the reorientation of the drop is a dual process: a threshold process in the region where the initial director orientation is orthogonal to the electric field, and a nonthreshold process elsewhere in the drop. A relation for determining the critical field is obtained. Experimental investigations of the characteristics of scattered light for a film of polymer-encapsulated liquid crystals confirm the computational results. (C) 1998 American Institute of Physics.

Заглавие : Composite polymer granules based on poly-ε-caprolactone and montmorillonite prepared by solution-casting and melt extrusion

Аннотация: Eco-friendly polymer composites in the form of granules based on biodegradable polycaprolactone (PCL) with the inclusion of montmorillonite (MMT) from 5 to 50 wt% were prepared by solution-casting and melt extrusion. The physicochemical properties of the composite granules were studied using FTIR spectroscopy, XRDA, DSC, and TGA methods. The paper presents comparative values of crystallinity of composite granules which depend on the method of measuring (XRDA, DSC). It was shown that the crystallinity of PCL/MMT granules was affected by the preparation method and by the MMT content, and that with increase in MMT content, crystallinity increased by up to 61–67%. The change in crystallinity of the granules also affected its biodegradation in soil. At the end of exposure in soil, the mass loss for the granules prepared by solution-casting was more than 90%, whereas for the composite granules prepared by extrusion it was less than 60%. Applying melt extrusion enabled obtaining intercalated composites with predictable features, whereas only mixed-structure microcomposites could be prepared by solution-casting.

Аннотация: A method to determine a value of the effective field in the intergrain medium of a granular superconductor is proposed. The space between superconducting grains is considered to be a Josephson medium where passage of the transport current causes dissipation and the effective field is superposition of external field H and the field induced by magnetic moments of superconducting grains. The method proposed is based on the comparison of hysteresis field dependences of magnetoresistance and magnetization and their relaxation at H=const. By the example of granular YBa2Cu3O7, it is shown that, in the region of weak fields, the effective field in the intergrain medium exceeds by far the external field, i.e., compression of a magnetic flux occurs.

Аннотация: A series of single crystals of Ni3-xCoxB2O6 compounds with the kotoite structure and with different concentrations of transition metal ions (x = 0; 0,19; 0,6; 0,93; 2) were obtained. The lattice parameters and atomic coordinates were determined using X-ray diffraction. The theoretical calculations using the WIEN2k package predict that nickel ions tend to occupy the 4f crystallographic position, while cobalt ions tend to occupy the 2a crystallographic positions. The study of the diffuse scattering spectra and comparison of the Racah parameters for the compounds Ni3B2O6 and Co2NiB2O6 provides experimental evidence that the nickel ions occupy crystallographic position 4f.

Аннотация: Magnetic microspheres with nonmagnetic acrylic glass core were fabricated using electroless deposition. There are favorable conditions for magnetic flux closure within each particle. As a result, the dipole-dipole interaction in the powder of such microspheres is reduced drastically. This is the key difference between powders of magnetic microspheres and powders of full magnetic spherical particles witch behavior is significantly affected by the dipole-dipole interaction. The magnetic hysteresis in the cobalt microspheres with nonmagnetic core is significantly large then in the full cobalt particles produced using the same technique.

Аннотация: Using data on the structure of plant leaves, specific features of light propagation in biophotoniccrystal structures have been established by the transfer matrix method. Splitting of the stopband in two bands has been found. The density of photonic states and the electromagnetic field value have been calculated. The occurrence of two photosystems (splitting of the stopband in two bands), the peculiarity of the long-wavelength quantum yield and its enhancement (Emerson effect), and water dissociation in the soft mode due to an increase in the electromagnetic field on the layers are explained.

Аннотация: The effect of thermal cycling and sintering temperature on the chemical and thermodynamic stability of the bulk multiferroic xLa0.7Pb0.3MnO3–(1 – x)PbTiO3 quasi-ceramic and ceramic composites has been experimentally investigated. It is shown that the limiting temperature of the long-term sample firing should not exceed 1070 K. It has been found that sintering at this temperature and/or short-term exposure of the samples at higher temperatures (up to 1220 K) significantly increase the sample compactness, stabilize the thermal expansion, and enhance the quality of the composites. It has been established that the component grain integrity is violated by shrinkage of the samples and a sharp change in their volume during the phase transition of a ferroelectric component.

Аннотация: Light scattering and transmission by a monolayer polymer dispersed liquid crystal film containing liquid crystal droplets with inhomogeneous anchoring of liquid crystal molecules at the polymer-droplet interface is considered theoretically and experimentally. The developed optical model is based on the anomalous diffraction and interference approximations of the theory of scattering of waves. It is applied to describe the interference quenching effect for the coherently transmitted light and electrically controllable symmetry breaking effect in small-angle structure of light scattered by film containing droplets with inhomogeneous anchoring. The analysis of transmittance and reflectance of the one-dimensional photonic crystals composed of monolayers is carried out. The formation of the photonic band gaps is analyzed.
