Laser processing of polymer films fabricated from phas differing in their monomer composition / T. G. Volova, A. I. Golubev, I. V.

P(3HB) -- copolymers -- films -- CO2 laser -- SEM -- AFM -- water contact angles -- MTT assay -- NIH 3T3 fibroblasts
Аннотация: The study reports results of using a CO2-laser in continuous wave (3 W; 2 m/s) and quasi-pulsed (13.5 W; 1 m/s) modes to treat films prepared by solvent casting technique from four types of polyhydroxyalkanoates (PHAs), namely poly-3-hydroxybutyrate and three copolymers of 3-hydroxybutyrate: with 4-hydroxybutyrate, 3-hydroxyvalerate, and 3-hydroxyhexanoate (each second monomer constituting about 30 mol.%). The PHAs differed in their thermal and molecular weight properties and degree of crystallinity. Pristine films differed in porosity, hydrophilicity, and roughness parameters. The two modes of laser treatment altered these parameters and biocompatibility in diverse ways. Films of P(3HB) had water contact angle and surface energy of 92° and 30.8 mN/m, respectively, and average roughness of 144 nm. The water contact angle of copolymer films decreased to 80–56° and surface energy and roughness increased to 41–57 mN/m and 172–290 nm, respectively. Treatment in either mode resulted in different modifications of the films, depending on their composition and irradiation mode. Laser-treated P(3HB) films exhibited a decrease in water contact angle, which was more considerable after the treatment in the quasi-pulsed mode. Roughness parameters were changed by the treatment in both modes. Continuous wave line-by-line irradiation caused formation of sintered grooves on the film surface, which exhibited some change in water contact angle (76–80°) and reduced roughness parameters (to 40–45 mN/m) for most films. Treatment in the quasi-pulsed raster mode resulted in the formation of pits with no pronounced sintered regions on the film surface, a more considerably decreased water contact angle (to 67–76°), and increased roughness of most specimens. Colorimetric assay for assessing cell metabolic activity (MTT) in NIH 3T3 mouse fibroblast culture showed that the number of fibroblasts on the films treated in the continuous wave mode was somewhat lower; treatment in quasi-pulsed radiation mode caused an increase in the number of viable cells by a factor of 1.26 to 1.76, depending on PHA composition. This is an important result, offering an opportunity of targeted surface modification of PHA products aimed at preventing or facilitating cell attachment.

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.

Аннотация: The aim of this study is to develop a manufacturing technique of polymethylmethacrylate (PMMA) nanospheres to produce a more stable opal template. Water-acetone mixture was used as a dispersion medium to synthesize a PMMA opal structure. Morphology features, IR vibrational spectra and glass transition temperatures of the PMMA nanospheres formed in the water-acetone dispersion medium (nanospheres A) have been studied comparing with the same prepared in distilled water solution without acetone (nanospheres B). A dependence of a shrinkage degree of the nanoparticles on the acetone volume has been investigated. It has been revealed that under an electron beam action the shrinkage degree of the nanospheres A is in the range of 7-16% while the shrinkage of the nanospheres B is 18-25% at the same conditions. The nanospheres A are less flexible and soft as compared to the nanospheres B. Additionally, an ability of the PMMA nanoparticles fabricated in the water-acetone dispersion medium to form the ordered opal structures is demonstrated to be the similar to the nanospheres B.

silicon nanomaterial -- Raman line-shape -- phonon -- quantum confinement
Аннотация: A comparative analysis of two Raman line-shape functions has been carried out to validate the true representation of experimentally observed Raman scattering data for semiconducting nanomaterials. A modified form of already existing phonon confinement model (PCM) incorporates two basic considerations, phonon momentum conservation and shift in zone centre phonon frequency. After incorporation of the above mentioned two factors, a rather symmetric Raman line-shape is generated which is in contrary to the usual asymmetric Raman line-shapes obtained from nanostructured semiconductor. By fitting an experimentally observed Raman scattering data from silicon nanostructures, prepared by metal induced etching, it can be established that the Raman line-shape obtained within the framework of PCM is a true representative Raman line-shape of sufficiently low dimensions semiconductors.

Admittance spectroscopy of dopants implanted in silicon and impurity state-induced AC magnetoresistance effect / D. A. Smolyakov, A. S. Tarasov, M. A. Bondarev [et al.] // Mater. Sci. Semicond.

Кл.слова (ненормированные):
Semiconductors -- Magnetoimpedance -- Impurities -- Implantation
Аннотация: A silicon structure doped with Ga using ion implantation has been investigated by admittance spectroscopy. It has been established that the presence of the Ga impurity, along with the B one, in the silicon structure leads to the appearance of the second peak in the temperature dependence of the real part of the impedance (admittance). Moreover, switching-on a magnetic field parallel to the sample plane shifts the singularities in the temperature curve to the high-temperature region. This results in the manifestation of both the positive and negative magnetoresistance effect upon temperature and magnetic field variation. It has been found by the standard admittance spectroscopy analysis of the impedance data that the energy structure of the investigated sample includes two interfacial energy levels ES1(0) = 42 meV and ES2(0) = 69.4 meV. As expected, these energies are consistent with the energies of B and Ga dopants. In a magnetic field, these levels increase by 3 meV for B and 2 meV for Ga, which induces the magnetoresistance effect. It has been demonstrated that the interfacial state-induced magnetoresistance effect can be tuned by ion implantation and dopant selection.

Кл.слова (ненормированные):
Quantum adiabatic algorithm -- Quantum annealing -- Qubit -- Qutrit -- Associative memory -- Memory capacity
Аннотация: When associative memory is implemented on the well-studied Hopfield network, patterns are recorded in the interaction constants between binary neurons. These constants are chosen so that each pattern should have its own minimum energy of the system described by the Ising model. In the quantum version of the Hopfield network, it was proposed to recall such states by the adiabatic change of the Hamiltonian in time. Qubits, quantum elements with two states, for example, spins with S=1/2 were considered as neurons. In this paper, for the first time, we study the function of associative memory using three-level quantum elements-qutrits, represented by spins with S=1. We record patterns with the help of projection operators. This choice is due to the need to operate with a state with a zero spin projection, whose interaction with the magnetic field vanishes. We recall the state corresponding to one of the patterns recorded in the memory, or superposition of such states by means of quantum annealing. To equalize the probabilities of finding the system in different states of superposition, an auxiliary Hamiltonian is proposed, which is turned off at the end of evolution. Simulations were performed on two and three qutrits and an increase in the memory capacity after replacing qubits with qutrits was shown.

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.

The synthesis, microstructure, transport and magnetic properties of Bi-based low density HTSC [Text] / M. I. Petrov [et al.] // J. Mater. Process. Technol. - 2005. - Vol. 161, Is. 1-2. - P58-61, DOI 10.1016/j.jmatprotec.2004.07.056. - Cited Reference Count: 4 . - APR 10. - ISSN 0924-0136
Аннотация: HTSC Bi1.8Pb0.3Sr2Ca2Cu3Ox of low density has been synthesized and its structural and physical properties have been studied. Scanning electron microscopy (SEM) image shows that the material obtained has porous "foam" structure. The levitation force measured for the porous Bi1.8Pb0.3Sr2Ca2Cu3Ox is appeared to be approximately the same as for polycrystalline YBCO of high density. These "foam" structures may be an ideal material for some practical applications of HTSCs in bulk form. (c) 2004 Elsevier B.V. All rights reserved.

Switch-on and switch-off tests of inductive high-T-c superconductor based fault current limiter in the short circuit regime / A. G. Mamalis [et al.] // J. Mater. Process. Technol. - 2005. - Vol. 161, Is. 1-2. - P42-45, DOI 10.1016/j.jmatprotec.2004.07.007. - Cited Reference Count: 6 . - APR 10. - ISSN 0924-0136
Аннотация: The prototype of a fault current limiter (FCL) based on Bi1.8Pb0.3Sr1.9Ca2Cu3Ox high temperature superconductor (HTSC) was tested on switch-on/switch-off processes in the short circuit regime. The switch-off processes may result in voltage and current jumps, accompanied by energy dissipation large enough to destroy the FCL. Experimental results, together with numerical simulations for switch-off processes are presented and discussed. (c) 2004 Elsevier B.V. All rights reserved.

Data Process. - 2023. - Vol. 59, Is. 6. - P. 693-702, DOI 10.3103/S8756699023060134. - Cited References: 32. - This work was supported by the Russian Foundation for Basic Research (Russian Center of Scientific Information), project no. 21-52-12018. - We are grateful to Dr. Irena Senkovska for the presented DUT-8 (Ni, Co) samples . - ISSN 8756-6990. - ISSN 1934-7944

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.

    Лабораторный комплекс по физике с элементами автоматизации измерений и обработки результатов / В. А. Орлов, Э. В. Григорьев // XI Международная конференция по фотонике и информационной оптике : сборник научных трудов. - Москва, 2022. - С. 218-221. - Библиогр.: . - ISBN 978-5-7262-2842-6
   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.
