copper electrodeposited composite coatings -- aluminum-oxide nanopowder -- alumina -- microstructure -- microhardness -- ultimate tensile strength
Аннотация: Copper electrodeposited composite coatings containing two types of aluminum-oxide powders with different dispersities (alumina Al2O3-1 and electroexplosive aluminum-oxide nanopowder Al2O3-2) are obtained during the work. The studies show that introducing the powders leads to a change in the microstructure of the composites and a change in the grain growth principles during the formation of the coatings. Refinement and ordering of the grain structure of the coatings occurs and twinning defects and texture are formed. The change in the formation of the microstructure of the composites leads to a change in some operational characteristics: an increase in the microhardness (by 10% in the composites with the addition of alumina and by more than 30% in the coatings with electroexplosive aluminum oxide) and ultimate tensile strength (by 20% in the composites with Al2O3-1 and almost 1.5-fold in the samples with Al2O3-2).

Transparent conductor -- Cracked template -- Cells perimeter peeling -- EMI shielding films
Аннотация: The problem of sputtering of thick metal films on micro and nanotemplates is important for obtaining mesh transparent conductors with excellent optoelectric characteristics. In this work, we demonstrate for the first time the possibility of controlling the degree of peeling of the cell perimeter from the substrate for a cracked template based on egg white by alternating the operations of moistening the template with saturated water vapor and shock drying with hot air. Local peeling of the cracked template cells perimeter makes it possible to increase the thickness of the metal sputtered on the cracked template by more than 1 µm, which is not achievable for other lithographic approaches. Our technique was used to obtain thick Ag meshes with a low sheet resistance of no more than 1.59 Ω/sq and a transparency of about 89.1%. The thick Ag meshes show a shielding efficiency (SE) of 49 dB or 99.998% of the incident power of an electromagnetic wave at a frequency of 1 GHz. In a sandwich geometry, thick Ag meshes, which simulates a real shielding window, the shielding efficiency (SE) reaches 71 dB with a transparency of more than 80%.

    Определение характеристик поверхности диэлектрических пластин с помощью рассеяния света / В. Г. Подопригора, С. А. Раковская // Международ. журн. прикл. и фундамент. исслед. - 2023. - № 6. - С. 59-62, DOI 10.17513/mjpfi.13554. - Библиогр.: 5 . - ISSN 1996-3955

Кл.слова (ненормированные):
неровность поверхности -- шероховатость -- сверхгладкие пластины -- корреляционная функция -- индикатриса рассеяния -- roughness parameters -- surface -- correlation function -- dielectrical plates -- scattering indicatrix
Аннотация: В работе предложен новый способ определения параметров шероховатостей и корреляционной функции (КФ) сверхгладких диэлектрических пластин. Способ основан на нахождении из экспериментальной индикатрисы рассеивания света коэффициентов разложения (КФ) в ряд по системе ортогональных функций с последующим вычислением среднеквадратичных отклонений высот неровностей поверхности σ и периода корреляции Т. Отличительными особенностями метода являются: 1) отсутствие неоднозначности, возникающей при подгонке к экспериментальной кривой рассеяния теоретических зависимостей с разными корреляционными функциями, которые сами зависят от параметров шероховатостей; 2) возможность избежать необходимости измерять индикатрису рассеяния во всей полусфере над образцом. Данный способ определения КФ и параметров шероховатости поверхности может применяться для любого типа границ раздела при соблюдении критерия Рэлея, определяющего степень неровности поверхности отражения по отношению к длине волны падающего излучения. Поэтому объектами исследования могут быть не только поверхности с нанометровыми шероховатостями, облучаемые лазерным светом, но и, например, земные покровы при их дистанционном зондировании радиосигналами навигационных спутников. Для полированных пластин кварца получены значения параметров поверхностей, близкие к аналогичным величинам, измеренным независимо на лазерном интерференционном профилометре другими авторами.
The paper proposes a new method for determining the roughness parameters and the correlation function (CF) of supersmooth dielectric plates. The method is based on finding the expansion coefficients (CF) from the experimental light scattering indicatrix in a series according to a system of orthogonal functions, followed by the calculation of the standard deviations of the surface irregularity heights σ and the correlation period Т. Distinctive features of the method are: 1) the absence of ambiguity that arises when fitting theoretical dependences with different correlation functions, which themselves depend on the roughness parameters, to the experimental scattering curve; 2) the possibility of avoiding the need to measure the scattering indicatrix in the entire hemisphere above the sample. This method for determining the CF and surface roughness parameters can be used for any type of interface, subject to the Rayleigh criterion, which determines the degree of roughness of the reflection surface with respect to the wavelength of the incident radiation. Therefore, the objects of study can be not only surfaces with nanometer roughness irradiated by laser light, but also, for example, earth covers during their remote sensing by radio signals from navigation satellites. For polished quartz plates, the values of the surface parameters were obtained close to similar values measured independently on a laser interference profilometer by other authors.

Asp. - 2022. - Vol. 647. - Ст. 129090, DOI 10.1016/j.colsurfa.2022.129090. - Cited References: 80. - This work was supported by the Russian Science Foundation grant No. 21-72-20158 .

Magnetic nanoparticles -- Iron oxide -- Magnetite -- Maghemite -- Glycine -- Mossbauer spectroscopy -- Coprecipitation
Аннотация: Iron oxide magnetic nanoparticles (MNPs) are of interest in biomedicine and research owing to their moderate cytotoxicity and advanced properties, such as extensive surface-to-volume ratio and possibilities for tailoring their functionality through surface chemistry. To date, various approaches have been used for the synthesis of MNPs with controllable structural properties and various coatings to enhance their stability and functionality. This study describes a modified one-step method of coprecipitation in the presence of glycine allowing the production of particles with controllable size and in situ surface decoration. The effect of different glycine concentrations on the morphostructural and magnetic properties of iron oxide MNPs is studied. The particle size is reduced from 10.2 ± 0.3 to 7.2 ± 0.5 nm by increasing the glycine concentration from 0.06 up to 0.60 mol. The magnetic properties of obtained particles were tracked by SQUID magnetometry and Mossbauer spectroscopy. All samples of glycine capped iron oxide MNPs showed superparamagnetic behaviour at room temperature with maximal value of the saturation magnetization of 69 ± 4 Am2/kg. The results show the optimal concentration range of glycine which can be used in this method: a lower concertation than 0.15 mol does not affect the properties of obtained particles while higher concentrations than 0.3 mol lead to the reduction of magnetic properties (the saturation magnetisation reduces to 59 ± 3 Am2/kg when glycine concentration was 0.6 mol). The proposed economic and environment-friendly approach can be utilized to synthesise –NH2 functionalised MNPs for biomedical or wastewater treatment.

Аннотация: The structural and magnetic properties of a niobium nitride (NbN) film prepared by reactive sputtering onto a quartz substrate are investigated. It is shown using scanning electron microscopy that the film has a columnar structure with a diameter of crystallite columns of about 50 nm. The film magnetization loops are measured for the field orientation parallel and perpendicular to its surface. Based on the experimental data, the critical current densities of the film are estimated in both cases. For the field parallel to the film surface, the estimate is 6.5 × 104 A/cm2 at the liquid helium temperature. For the field perpendicular to the surface, the critical current density is close to the depairing current density (107 A/cm2). Analysis of the results based on different models of magnetic vortex pinning in superconductors shows that in the former case, pinning occurs at the boundaries of columns in the bulk of the sample, while in the latter case, it is determined by the influence of the surface barrier.

Аннотация: The voltage dependences of polarization characteristics of light passed through the cholesteric layers with tangential-conical boundary conditions have been investigated. It has been shown that such layers allow turning the polarization azimuth more than 70˚ because of the unique untwisting effect of the cholesteric helix, due to free azimuthal rotation of the director on the substrate with conical anchoring. Optical cells under study have some advantages (low control voltage, smooth variation of polarization azimuth, simplicity of design) and can be used as an electrically controlled polarization rotator of white light.

Bigraphene -- g-C3N4 -- Transition metal -- Adsorption -- Migration
Аннотация: First-row transition metal (TM) atoms adsorption and migration on nanoporus 2D materials like bigraphene with double vacancies and g-C3N4 as the active sites for TM nanocluster's growth was studied within the framework of density functional theory. Both thermodynamic and kinetic aspects of composite synthesis were discussed. It was found that potential barriers of adatom's migration from bigraphene's outer surface to the interlayer space through the double vacancy are rather low values. High potential barriers of TM migration along the carbon plane prevents TM clusterization due to enhanced chemical activity of double vacancies which gives a possibility to capture the surface adatoms. As was shown for the monolayer graphene, the decrease of vacancies concentration reduces the barrier of adatom migration along the surface while the second graphene sheet in bigraphene stabilizes the structure. The behavior of TM-atom regarding g-CN2 and g-CN1 nanosheets was investigated. Potential energy surfaces were obtained and discussed. The migration barriers were found surmountable that means high probability of migration of TM adatoms to global minima and formation of TM vacancies. Comparison of barriers values with Boltzmann factor demonstrated that just standalone temperature fluctuations cannot initiate structural transitions. The properties of designed structures can be of interest of catalysts and biosensors for biomedical applications.

UV pump-x-ray probe -- molecular spectroscopy -- ultrafast dynamics -- potential energy surfaces -- x-ray absorption
Аннотация: In theoretical simulations of a UV + x-ray pump-probe (UVX-PP) setup, we show that frequency detuning of the pump UV pulse acts as a camera shutter by regulating the duration of the UVX-PP process. This two-photon absorption with long overlapping UV and x-ray pulses, allowing for high spectral resolution, thereby provides information about ultrafast dynamics of the nuclear wave packet without the requirement of ultrashort pulses and controlled delay times. In a case study of carbon monoxide, the calculated UVX-PP spectra of the O1s−12π1 and C1s−12π1 core-excited states show different vibrational profiles. The interference of intermediate vibrational states reveals details of nuclear dynamics in the UVX-PP process related to a variable duration time controlled by the UV detuning. Both O1s−12π1 and C1s−12π1 pump-probe channels display a splitting of the spectral profile, which however is associated with different physical mechanisms. At the O1s−12π1 resonance, the observed dispersive and non-dispersive spectral bands intersect and result in destructive interference.
