    High-strength building material based on a glass concrete binder obtained by mechanical activation / S. S. Dobrosmyslov, V. E. Zadov, R. A. Nazirov [et al.] // Buildings. - 2023. - Vol. 13, Is. 8. - Ст. 1992, DOI 10.3390/buildings13081992. - Cited References: 26 . - ISSN 2075-5309

glass -- building materials -- mechanical activation -- waste processing
Аннотация: As part of the work, the chemical interaction of finely ground glass (~1 μm), calcium oxide, and water was studied. It is shown that an increase in the fineness of grinding makes it possible to abandon autoclave hardening in the production of products on a hydrosilicate binder. The study of chemical interaction was carried out by calculating the thermodynamic equilibrium and was also confirmed by XRD analysis. DTA analysis showed that an increase in the treatment temperature leads to an increase in the proportion of the reacted phase at the first stage. Subsequently, phase formation is associated with the presence of CaO. The carrier of strength characteristics is the CaO×2SiO2×2H2O phase. The selection and optimization of the composition make it possible to obtain a high-strength glass concrete material with a strength of about 110 MPa. The micrographs of the obtained samples correspond to classical hydrosilicate systems.

Lateral photovoltaic effect in silicon-based hybrid structures under external magnetic field / I. A. Bondarev, M. V. Rautskii, N. V. Volkov [et al.] // Mater. Sci. Semicond. Process. - 2023. - Vol. 167. - Ст. 107786, DOI 10.1016/j.mssp.2023.107786. - Cited References: 32 . - ISSN 1369-8001. - ISSN 1873-4081
Кл.слова (ненормированные):
Lateral photovoltaic effect -- MIS structures -- Interface states -- Schottky field
Аннотация: Charge transport in semiconductor devices is highly sensitive to light, which opens up wide application prospects. The lateral photovoltaic effect (LPE) is widely used in position sensitive detectors due to its high sensitivity to the light spot position. We report on the features of the LPE in silicon-based metal/insulator/semiconductor structures at helium temperatures. To investigate the LPE, Fe/SiO2/p-Si and Mn/SiO2/n-Si structures have been fabricated by molecular beam epitaxy. It has been found by studying the lateral photovoltage that the SiO2/Si interface plays a significant role in transport of photogenerated carriers, mainly via the interface states, which induce electron capture/emission processes at certain temperatures. The value of the photovoltage is likely affected not only by the metallic film thickness, but also by the substrate conductivity type and Schottky barrier. The effect of the magnetic field on the LPE is driven by two mechanisms. The first one is the well-known action of the Lorentz force on photogenerated carriers and the second one is shifting of the interface state energy levels. Basically, the magnetic field suppresses the contribution of the interface states to the LPE, which suggests that the interface-induced transport can be controlled magnetically.

    Modification of polyhydroxyalkanoates polymer films surface of various compositions by laser processing / E. I. Shishatskaya, N. O. Zhila, A. E.

PHAs -- polymer films -- CO2 laser -- laser processing -- SEM -- AFM -- water contact angles -- fibroblast NIH 3T3 -- MTT test
Аннотация: The results of surface modification of solvent casting films made from polyhydroxyalkanoates (PHAs) of various compositions are presented: homopolymer poly-3-hydroxybutyrate P(3HB) and copolymers comprising various combinations of 3-hydroxybutyrate (3HB), 3-hydroxyvalerate (3HV), 4-hydroxybutyrate(4HB), and 3-hydroxyhexanoate (3HHx) monomers treated with a CO2 laser in continuous and quasi-pulsed radiation modes. The effects of PHAs film surface modification, depending on the composition and ratio of monomers according to the results of the study of SEM and AFM, contact angles of wetting with water, adhesion and growth of fibroblasts have been revealed for the laser radiation regime used. Under continuous irradiation with vector lines, melted regions in the form of grooves are formed on the surface of the films, in which most of the samples have increased values of the contact angle and a decrease in roughness. The quasi-pulse mode by the raster method causes the formation of holes without pronounced melted zones, the total area of which is lower by 20% compared to the area of melted grooves. The number of viable fibroblasts NIH 3T3 on the films after the quasi-pulse mode is 1.5–2.0 times higher compared to the continuous mode, and depends to a greater extent on the laser treatment mode than on the PHAs’ composition. The use of various modes of laser modification on the surface of PHAs with different compositions makes it possible to influence the morphology and properties of polymer films in a targeted manner. The results that have been obtained contribute to solving the critical issue of functional biodegradable polymeric materials.

Кл.слова (ненормированные):
Raman light scattering -- metal-organic framework -- pore orientation -- electron density functional theory
Аннотация: A method for the determination of pore orientation in metal-organic framework structures by polarized Raman spectra is proposed. The method involves sensitivity of the line intensity of Raman scattering to the geometry of propagation in a crystal. The operability of the method is shown by DUT-8 (Ni, Co) crystals. The obtained results are interpreted based on analysis of symmetry and direction of vibrations within periodic calculations of the electron density functional theory. The simultaneous approach allowed us to describe the vibrations and to find the principal crystal orientation collinear to the pore direction. The information on the pore orientation is necessary for problems of adsorption and design of complex multicomponent materials based on metal-organic framework.

biodegradable polymers -- poly-ε-caprolactone -- montmorillonite -- polymer composites -- processing technologies
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.

Quantum adiabatic algorithm -- Quantum annealing -- Qutrit -- Clustering
Аннотация: Clustering is grouping of data by the proximity of some properties. We report on the possibility of increasing the efficiency of clustering of points in a plane using artificial quantum neural networks after the replacement of the two-level neurons called qubits represented by the spins S = 1/2 by the three-level neurons called qutrits represented by the spins S = 1. The problem has been solved by the slow adiabatic change of the Hamiltonian in time. The methods for controlling a qutrit system using projection operators have been developed and the numerical simulation has been performed. The Hamiltonians for two well-known clustering methods, one-hot encoding and k-means, have been built. The first method has been used to partition a set of six points into three or two clusters and the second method, to partition a set of nine points into three clusters and seven points into four clusters. The simulation has shown that the clustering problem can be effectively solved on qutrits represented by the spins S = 1. The advantages of clustering on qutrits over that on qubits have been demonstrated. In particular, the number of qutrits required to represent N data points is smaller than the number of qubits by a factor of log 2N/ log 3N. For qutrits, the simplest is to partition the data points into three clusters rather than two ones. At the data partition into more than three clusters, it has been proposed to number the clusters by the numbers of states of the corresponding multi-spin subsystems, instead of using the numbers of individual spins. This reduces even more the number of qutrits (Nlog 3K instead of NK) required to implement the algorithm.

Аннотация: The structure, transport characteristics, real and imaginary parts of the impedance components and electric polarization of the HoXMn1-XS (X = 0.1 and 0.2) system have been investigated in the temperature range of 80-500 K in magnetic fields of up to 12 kOe. The morphology of synthesized samples has been studied. The influence of the magnetic field on the transport characteristics, on both direct and alternating currents of holmium manganese sulfides, have been established. The negative effects of DC magnetoresistance in the region of the magnetic phase transition and positive AC magnetoimpedance up to 4% in the paramagnetic region have been established. The critical temperatures of the existence of the electric polarization have been determined. At a substitution concentration of X = 0.1, the activation character of the relaxation time versus temperature has been found. The diffusion contribution for the composition with X = 0.2 has been established by the impedance hodograph.

   Перевод заглавия: Laboratory complex in physics with elements of automation of measurements and processing of results
Аннотация: Многие студенты инженерных специальностей университетов уже в школьные годы прошли хорошую подготовку в специализированных физико-математических классах, насыщенную физическим экспериментом. Оказавшись в стенах университета, такой студент вновь оказывается в физической лаборатории, где предлагаются вполне стандартные, уже знакомые, опыты (с незначительными вариациями). Это обстоятельство тормозит развитие пытливого ума, приводит к нерациональной трате материальных средств, оборудования, времени студента и преподавателя. Предлагаемый проект направлен на проектирование и создание комплекса лабораторного физического практикума и демонстрационного эксперимента, отвечающего современному уровню развития физической науки.
Many students of engineering specialties of universities, already in their school years, were well trained in specialized physics and mathematics classes, saturated with physical experiments. Once within the walls of the university, such a student again finds himself in a physics laboratory, where quite standard, already familiar, experiments are offered (with minor variations). This circumstance inhibits the development of an inquiring mind, leads to an irrational waste of material resources, equipment, time of the student and teacher. The proposed project is aimed at designing and creating a complex of laboratory physical practice and a demonstration experiment that meets the modern level of development of physical science.
