    Influence of the filler particles’ surface morphology on the polyurethane matrix’s structure formation in the composite / T. A. Shalygina, M. S. Rudenko, I. V.

Аннотация: This article presents the surface morphology effect of silicon carbide (SiC) particles on the polyurethane binder’s structure formation in a dispersed-filled composite. The difference in the morphology and surface relief of filler particles was ensured by the implementation of plasma chemical modification. As a result of this modification, the filler consisted of core-shell particles characterized by a SiC core and a carbon shell (SiC@C), as well as a carbon shell decorated with silicon nanoparticles (SiC@C/SiNP) or nanos (SiC@C/SiNW). The study of the relaxation properties of polyurethane composites has shown that the strongest limiting effect on the molecular mobility of boundary layer’s chain segments is exerted by a highly developed surface with a complex relief of SiC@C/SiNP and SiC@C/SiNW particles. An empirical method was proposed to find the polymer fractions spent on the formation of the boundary, transition and bulk layers of the polymer matrix in the composite. It was shown that the morphology of the filler particles’ surface does not affect the dependence of the boundary layer thickness on the filler’s volume fraction. However, with an increase in the degree of surface development, the boundary layer thickness decreases.

   Перевод заглавия: Ferromagnetic resonance in Cо-Ni composite nanorods in polycarbonate track etched membrane
Аннотация: Пористый полимер, наполненный сегментированными наностержнями из магнитного металла, перспективен для создания новых микроволновых устройств. Массивы двухсегментных стержней Ni/Co и коаксиальных стержней Ni@Co получены методом химического осаждения в поликарбонатную трековую мембрану. Внутреннее эффективное магнитное поле магнитных композитных наностержней, упорядоченных на немагнитной подложке, исследовано с помощью ферромагнитного резонанса. Установлено влияние межфазных границ для двух типов стержней на эффективное поле. Обнаружено, что характеристиками ФМР можно управлять с помощью конструкции стержня (ядро-оболочка или двухсегментный стержень), свойств матрицы (пористость) и условий химического осаждения.

Study of a composite consisting of metal nanoparticles in a dielectric matrix and multilayer bandpass filters based on it / B. A. Belyaev, An. A. Leksikov, V. V. Tyurnev, D. A. Shabanov // Dokl.

Кл.слова (ненормированные):
composite -- metal nanoparticles -- complex permittivity -- bandpass filter
Аннотация: The frequency and concentration dependences of the effective complex permittivity of a composite consisting of silver nanoparticles in a polystyrene dielectric matrix have been investigated. It has been found that, with an increase in the volume concentration of particles in the composite to ~33%, the real part of its permittivity increases from 2.6 to ~103, while the loss tangent remains no higher than 10–2 up to a frequency of 1 THz. We show the possibility of designing bandpass filters based on composite layered structures, which can be tuned by selecting the particle concentration in the quarter-wavelength layers of the mirrors that ensure the optimal interaction of half-wavelength resonators with each other and the outer resonators with free space. The high contrast between the matrix and the composite permittivities makes it possible to create mirrors with a required reflectivity using a minimum number of layers.

Аннотация: Splitting of a Tamm plasmon polariton at the interface between a metal and a nanocomposite layer conjugated with a photonic crystal (Bragg mirror) has been theoretically investigated. The splitting can be implemented when the Tamm plasmon polariton frequency approaches the resonance frequency of the nanocomposite, which consists of metallic nanoballs dispersed in a transparent matrix. The reflectance spectrum of the p-polarized waves at the normal incidence of light has been calculated. It has been established that the Tamm plasmon polariton splitting significantly depends on the concentration of nanoballs in the nanocomposite layer and its thickness. The solution of the dispersion equation derived for a sample with semi-infinite mirrors has been compared with the spectra obtained for a finite structure by the transfer matrix method.

Кл.слова (ненормированные):
cobalt–copper composite material -- chemical deposition -- magnetic properties -- amorphous bulk alloys -- dynamic compaction
Аннотация: The work reports a magnetostructural study of bulk nanostructured composite materials Co–P/Cu prepared by dynamic compaction (DC) and uniaxial cold pressing (CP). The initial particles with amorphous and crystalline structure are synthesized by chemical deposition. Magnetic characteristics of composites (saturation magnetization, Bloch constant, local anisotropy field, ferro-magnetic resonance line width, coercive force) are studied. The phase compositions of initial composite particles and compacts prepared by two methods (DC and CP) are determined from the anisotropy field and the Bloch constant values using magnetic phase analysis. It is shown that the use of composite particles in dynamic compaction allows obtaining homogeneous nanostructured bulk materials while preserving magnetic characteristics of initial powders.

Аннотация: Pulsed-field gradient NMR spectroscopy and magnetic resonance imaging methods were used to investigate water suspensions of nanosized fibers of aluminum oxide and ice composite materials based on these fibers. Introduction of the nanofibers was shown to have no noticeable structural effect in the suspensions in the Al2O3 concentration range of 1-10 wt %. High content of the filler was found to change the morphology and texture of the ice matrix in the composites remarkably: it becomes more homogeneous and acquires a higher degree of continuity; the melting front does not visualize internal melting zones or integrity defects in the composite. At the same time, addition of the nanofibers to the ice composites weakly influences the quantitative dynamics of the heat transfer, which is manifested in close values of the propagation speeds of the freezing/melting front in the samples at similar temperatures.

Аннотация: The magnetic and resonance properties of the DyMn2O5–Mn3O4 nanoparticle composite have been experimentally investigated. Two magnetic transitions at temperatures of T1 ≈ 65 K and T2 ≈ 230 K have been established; the T1 value differs from the temperatures of the transitions in the initial materials, which has been attributed to the interparticle interactions. Temperature T2 corresponds to the DyMnO3 impurity phase (1 at %). Three microwave absorption peaks have been observed in the magnetic resonance spectrum, which is explained within the model of a magnetically two-phase system. One resonance is attributed to Mn3O4, and the other two peaks are attributed to an ensemble of highly anisotropic DyMn2O5 particles with a random distribution of anisotropy axes.
