Кл.слова (ненормированные):
диэлектрическая модель -- влажность -- температура -- органическая почва -- минеральная почва -- мерзлая почва -- талая почва -- dielectric model -- moisture -- temperature -- organic soil -- mineral soil -- frozen soil -- thawed soil
Аннотация: На основе рефракционной диэлектрической модели создана одночастотная диэлектрическая модель талых и мерзлых лесных почв корневой зоны, учитывающая влияние как минеральной, так и органической компоненты почвенной смеси. Модель разработана для частоты 435 МГц на основе диэлектрических измерений пяти почв, в которых содержание органического вещества варьировалось от 11,1 до 54,4 % и глины от 21,1 до 40,9 %. Диэлектрические измерения были проведены в диапазоне массовой влажности от сухого состояния до наименьшей влагоемкости и диапазоне температур от – 30 до 25 ℃. В исследуемом диапазоне температур коэффициент детерминации между рассчитанными с использованием предложенной модели и измеренными значениями действительной (ε') и мнимой (ε") частями комплексной диэлектрической проницаемости составляет 0,988 – 0,997 для ε' и 0,957 – 0,971 для ε". Нормированное среднеквадратическое отклонение при этом составило 6 – 5,6 % для ε' и 20,2 – 21,2 % для ε". Разработанная диэлектрическая модель может быть применена в алгоритмах дистанционного зондирования при восстановлении значения влажности лесных почв корневой зоны из данных радарного и радиометрического зондирования.
The single-frequency dielectric model of thawed and frozen forest soils in the root zone based on the refractive dielectric model was created, taking into account the influence of both the mineral and organic components of the soil mixture. The dielectric model was created on at 435 MHz the basis of the laboratory dielectric measurements of five soils with organic matter content in the range from 11.1 to 54.4 % and clay content from 21.1 to 40.9 %. Dielectric measurements were carried out in the range of the gravimetric moisture from the dry state to the lowest moisture capacity and in the temperature range from –30 to 25 ℃. The coefficient of determination between the predicted and measured values for real and imaginary parts of the complex permittivity are 0.988 - 0.997 and 0.957 - 0.971, respectively. The normalized standard deviations in this case are 6 - 5.6 % and 20.2 - 21.2 % for real and imaginary parts of the complex permittivity, respectively. The developed dielectric model can be used in remote sensing algorithms of soil moisture retrieval of forest soils in the root zone from the data radar and radiometric.

   Перевод заглавия: Investigation of ordered configurations in transition metal MXene alloys depending on composition
Аннотация: Двумерные карбиды и нитриды переходных металлов, известные как MXены, привлекают все большее внимание. В настоящее время около 20 из них синтезированы и изучается их применение в самых разных областях: от хранения энергии до медицинских приложений. Для облегчения поиска новых MXенов, содержащих ранние переходные металлы, в данной работе в рамках теории функционала плотности и метода кластерного разложения мы исследуем взаимосвязь структура-стабильность для ряда упорядоченных сплавов MXенов, а именно Cr1-xMnx)3C2, (Ta1-x Crx)3C2, (Ta1-xMnx)3C2, (V1-x Crx)3C2 с 0 ≤ x ≤ 1. Используемый подход позволяет проанализировать энергии образования большого числа различных упорядоченных конфигураций и исследовать стабильность их предшественников MAX-фаз для выяснения возможности синтеза высокоупорядоченных MXенов.

Photo-biological effectiveness of PAR for radish plant communities irradiated using an LED source with an adjustable spectrum / A. A. Tikhomirov, M. S. Molokeev, V. V.

Кл.слова (ненормированные):
spectral composition of radiation -- spectral effectiveness of radiation -- variable radiation spectrum -- fluorescent LEDs -- radish productivity
Аннотация: The aim of the current study was to find the most effective spectral modes of irradiation of short-season plants (for example, radish) using a fluorescent LED irradiator with a variable spectrum. The research methodology was based on the species-specific response of plants to the spectral composition of light. Photo-biological experiments were carried out to find effective spectral composition of PAR for cultivating radish communities under stable and variable irradiation modes of electrical lighting. It was shown that under stable irradiation modes, the highest productivity of economically useful radish biomass had been achieved at spectral composition with a maximum of 60 % radiation in the (600–700) nm region in a variable spectral irradiation mode. The variable spectral irradiation mode turned out to be the most effective when the spectral composition with the dominance of red rays was changed to the spectral composition with the dominance of blue rays. There were no significant differences between the best production parameters for stable and variable modes of irradiation of radish plants, which indicates the expediency of choosing the stable spectral mode of irradiation of radish plants as a short-season crop under electrical illumination. The results obtained can be used to select spectral irradiation modes for short-season plants grown under electrical lighting in northern regions and in isolated rooms in various climatic zones using "City-farm" technologies.

Concrete optimization -- Random forest -- Decision tree -- Machine learning -- Сement concrete roads
Аннотация: Current manuscript presents a study on the use of 48 experimental data points containing parameters of concrete production technological process and its properties, such as strength, density, and bending strength. It was revealed that temporal characteristics, specifically - compressive strength at the age of 3, 7, 28 days, R3, R7, and R28, are significantly correlated with each other, indicating that only one characteristic, such as R28 or Rfl 28, is sufficient for prediction. The absence of multiple correlations between parameters and properties suggests that linear regression analysis may not be accurate. Therefore, the use of Machine Learning is optimal; specifically Random Forest method is preferable due to ease of use and minimum hyperparameters for tuning. Low prediction errors (?1–11%) for 30% of the test data, as determined by the cross-validation method, confirm a relationship between the experimental parameters and the concrete properties. The most important parameters for achieving high values of compressive and bending strengths, R28 and Rfl 28, were identified, namely: air-entraining additives, granite crushed stone consisting of a mixture of fractions 5–20 mm, crushed stone derived from gravel of high strength grains of large fractions 10–20 mm. To obtain explanatory model, another Machine Learning method, that was used, called Decision Tree. The model showed that a high amount of crushed stone 10–20 mm from gravel, more than 212 (kg per 1 m3 of concrete mix), leads to a higher number of strong grains with smooth, rounded surface, thereby, reducing the bending strength of concrete. However, a large concentration of crushed stone mix fractions of 5–20 mm from granite, more than 537 (kg per 1 m3 of concrete mix), leads to the maximum roughness, which makes a significant contribution to the increased strength of concrete due to the adhesion of the matrix and aggregates to each other.

Кл.слова (ненормированные):
biosynthesis -- different precursors -- sulfur-containing PHAs -- chemical composition -- 3MP monomers contents -- properties
Аннотация: The study addresses the growth of the wild-type strain Cupriavidus necator B-10646 and the synthesis of sulfur-containing polyhydroxyalkanoates (PHA) by this strain on media containing fructose and three different precursors (3-mercaptopropionic acid, 3′,3′-dithiodipropionic acid and 3′,3′-thiodipropionic acid). By varying the concentration and number of doses of the precursors added into the bacterial culture, it was possible to find conditions that ensure the formation of 3-mercaptopropionate (3MP) monomers from the precursors and their incorporation into the C-chain of poly(3-hydroxybutyrate). A series of P(3HB-co-3MP) copolymer samples with different content of 3MP monomers (from 2.04 to 39.0 mol.%) were synthesized and the physicochemical properties were studied. The effect of 3MP monomers is manifested in a certain decrease in the molecular weight of the samples and an increase in polydispersity. Temperature changes are manifested in the appearance of two peaks in the melting region with different intervals regardless of the 3MP content. The studied P(3HB-co-3MP) samples, regardless of the content of 3MP monomers, are characterized by equalization of the ratio of the amorphous and crystalline phases and have a close degree of crystallinity with a minimum of 42%, = and a maximum of 54%.

Photocatalytic water splitting -- Novel materials -- Transition metal dichalcogenides -- H2 generation
Аннотация: The successful fabrication of H-phase Janus transition metal dichalcogenides (TMDs) has received considerable interest due to its great potential in photocatalytic applications. Here, new A′-XMoY (X/Y = O, S, Se, Te) Janus-type structures belonging to the family of TMDs were theoretically investigated for the first time in terms of photocatalytic water splitting via DFT calculations. For all compounds, the Raman spectra were calculated. The SMoO, SeMoO, SMoSe, SMoTe and SeMoTe compounds are dynamically stable and are semiconductors. Among all considered structures SMoTe is the most promising candidate for solar hydrogen production because valence and conduction bands perfectly engulf the redox potentials of water at both neutral and acidic media, opposite to SMoSe, SMoO, SeMoO suitable only in the acidic media, and SeMoTe – in the neutral media. Moreover, A′-SMoTe demonstrates the outstanding values of the solar-to-hydrogen (STH) conversion efficiencies of 54.0 and 67.1 for neutral and acidic media.

Аннотация: A comparative study of the magnetic properties of arrays of Co–Ni rods with different composition gradients (smooth or step-like) along the rod axes was carried out. Ordered arrays of Co–Ni nanorods with diameters up to 400 nm and 8 µm length were prepared by electroless plating into a porous nuclear-track-etched polycarbonate membrane. The gradient in Co and Ni composition was confirmed by energy-dispersive X-ray analysis. The variation of Co–Ni contents along the long axis of the rods correlates with the gradient of the magnetization within the rod. Magnetization reversal was studied by analyzing the angular dependence of coercivity and using micromagnetic simulations. For both types of gradient rods, reversal occurs by curling. The local magnetic anisotropy field of rods with a step-type gradient is significantly higher than that for rods with a smooth gradient.

Аннотация: The comparison between the magnetic properties of materials with different curvature and spatial distribution of nanograins, such as particles (3D spatial distribution) and multilayer films (2D) was carried out. Functionally graded Co(P)/Ni(P) and Co(P)/CoNi(P) specimens have been fabricated by electroless deposition. The magnetic and structural properties are characterized by electron microscopy, X-ray diffraction, ferromagnetic resonance spectroscopy, and vibrating sample magnetometer. It was demonstrated that the interaction between the Ni(P) core and Co(P) shell of particles could form the functionally graded materials with tailored structure and coercive force. Furthermore, it was found that the magnetic parameters (the local anisotropy field, ferromagnetic resonance linewidth, and coercivity) are mainly determined by the artificially created interface boundaries for all grains’ spatial distribution. The magnetic anisotropy field and coercivity of Co(P)/Ni(P) flat films were characterized by lower values than those for spherical shell of particles with the same composition, produced by the same method.

Аннотация: The paper reports microstructures (revealed by transmission electron microscopy) in various zones of laser welds of the X70 and X80 low-carbon steels with different initial microstructures, as well as chemical and phase compositions. In the X70 steels with 0.13% C, the microstructure refinement has been achieved through helical rolling at temperatures of 920 °C and 850 °C (designated as X70-920 and X70-850, respectively). For all studied cases, both initial steel microstructures and phase compositions have determined the formation of different microstructures with various microhardness levels in the weld metal and heat-affected zones. For the X70-850 steel with a more dispersed and homogeneous microstructure (dF = 3.3 μm), a lower microhardness level of 340 HV has been observed in the weld metal, compared with the X70-920 one (dF = 5.5 μm, 370 HV). The reason has been the formation of both bainite and martensite laths in the X70-850 weld metal, while only lath and lamellar martensite has formed in the X70-920 one. For the X80 steel (0.55% C), lowering the carbon content and additional microalloying with chromium, molybdenum and nickel have enabled to decrease the microhardness level down to 295 HV in the weld metal due to the degenerate upper bainite formation and the carbon level reduction in martensite. The dispersed and homogeneous initial microstructures of the X70-850 and X80 steels has provided the formation of granular ferrite-bainite microstructures in the intercritical heat-affected zone. They have possessed a lower proportion of residual austenite regions and small sizes of twinned martensite areas. The welded X80 steel specimen has been characterized by higher ductile properties compared to both X70 ones.

Аннотация: To reach the concentration phase boundary between antiferromagnetic Cu2GaBO5 and ferrimagnetic Cu2MnBO5 ludwigites, solid solutions Cu2Mn1−xGaxBO5 (x = 0.05, 0.1, 0.15, 0.175) were grown by the flux technique using a multi-component solvent based on Bi2Mo3O12 with the addition of Na2B4O7 which significantly influenced the crystal formation and cation composition of the studied compounds. The content of the flux system was corrected taking into account the earlier established relationship of the partition coefficients of Mn2O3 and Ga2O3. The influence of the solvent components on the ludwigite crystallization was analyzed. The maximum size of the grown crystal was 1 × 1 × 4 mm3. The structure and cation composition of the grown compounds were studied using X-ray (X-ray diffraction, EDX (energy-dispersive X-ray spectroscopy)) and vibrational (Raman) spectroscopy techniques. The phase boundary of Cu2MnBO5–Cu2GaBO5 was found to be in the concentration range of x = 0.15–0.175, corresponding to a change in the monoclinic axis direction and a leap in the lattice parameters. The symmetry evolution of metal–oxygen octahedra for four nonequivalent cation positions was analyzed, and the unique crystal structure of Cu2MnBO5 demonstrated high rigidity relative to the introduction of Ga3+ cations. The polarized Raman spectra of monoclinic ludwigites were obtained and studied for the first time. A comparison of the spectra of the studied samples in both phases and orthorhombic ludwigites was made. A number of spectral features due to the monoclinic distortions in the crystal were found. In agreement with the Raman experiment, the concentration phase boundary was close to 0.15.

Аннотация: The effect of surfactants on the structure, morphology, and magnetic properties of FexSy iron-sulfide nanoparticles synthesized by thermal decomposition is studied. Oleylamine, hexadecylamine, and octadecylamine are used as surfactants. It is established by X-ray and electron-diffraction analysis combined with Mossbauer spectroscopy that, in samples 1 and 2 prepared using oleylamine and hexadecylamine, respectively, the Fe3S4 greigite phase dominates, with an inverse spinel structure isostructural to the iron oxide Fe3O4 magnetite with minor Fe9S11 impurities. Deviations in the distribution of iron cations over the tetrahedral and octahedral sites relative to the bulk greigite crystals are observed. The nanoparticles synthesized using octadecylamine (sample 3) are found to be multiphase with a greigite fraction of ~20%. In all three cases, as showed the results of transmission electron microscopy and Fourier transform infrared spectroscopy together with thermogravimetry analysis, the magnetic nanoparticles have an organic shell chemically bonded to their magnetic core, which prevents the agglomeration of the particles. This shell is much more massive in samples 2 and 3. The magnetization values for samples 1 and 2 are similar to those of greigite nanoparticles reported in publications, while the magnetization of sample 3 is several times lower, in accordance with the greigite fraction in it. The combination of fairly high magnetization with a massive organic shell allows one to consider hexadecylamine to be a promising surfactant for the synthesis of iron-sulfide nanoparticles protected from external impact and agglomeration.

Аннотация: Investigation of the temperature evolution of magnetization curves near magnetic saturation makes it possible to extract new information on the features of the phase composition and structure of hypoeutectoid steel. It is shown that the main contribution to the magnitude and the temperature behavior of the energy density of the local magnetic anisotropy of hypoeutectoid steel is due to the lamellar structure of pearlite. The peculiarity of the temperature behavior of the energy of the magnetic anisotropy, along with the behavior of the paraprocess, indicates the formation of Mn-substituted cementite in the studied steel sample. The observation of the crossover of power-law regularities in the approximation of magnetization to saturation indicates the formation of two-dimensional nano-inhomogeneities of the local axis of easy magnetization in the plates of alpha iron, which are part of the pearlite.

Cupriavidus necator B-10646 -- γ-valerolactone -- biomass concentration -- content and composition of copolymers -- P(3HB-co-3HV-co-4HV) -- physicochemical properties -- films -- surface properties
Аннотация: Synthesis of P(3HB-co-3HV-co-4HV) copolymers by the wild-type strain Cupriavidus necator B-10646 on fructose or sodium butyrate as the main C-substrate with the addition of γ-valerolactone as a precursor of 3HV and 4HV monomers was studied. Bacterial cells were cultivated in the modes that enabled production of a series of copolymers with molar fractions of 3HV (from 7.3 to 23.4 mol.%) and 4HV (from 1.9 to 4.7 mol.%) with bacterial biomass concentration (8.2 ± 0.2 g/L) and PHA content (80 ± 2%). Using HPLC, DTA, DSC, X-Ray, SEM, and AFM, the physicochemical properties of copolymers and films prepared from them have been investigated as dependent on proportions of monomers. Copolymers are characterized by a reduced degree of crystallinity (Cx 38–49%) molecular weight characteristics Mn (45–87 kDa), and Mw (201–248 kDa) compared with P(3HB). The properties of the films surface of various composition including the porosity and surface roughness were studied. Most of the samples showed a decrease in the average pore area and an increase in their number with a total increase in 3HV and 4HV monomers. The results allow scaling up the productive synthesis of P(3HB-co-3HV-co-4HV) copolymers using Cupriavidus necator B-10646.
