Ключевые слова (''Своб.индексиров.''): tamm plasmon--nanocomposite--photonic crystal--core-shell particles
Аннотация: Spectral peculiarities of the structure consisting of a photonic crystal coated with a nanocomposite (NC) have been investigated. The NC used contains spheroidal nanoparticles with a dielectric core and a metallic shell, which are uniformly dispersed in a transparent matrix. The spectral manifestation of the observed Tamm plasmon polariton (TPP) and Fabry-Perot mode has been examined. A significant polarization sensitivity of the spectra upon variation in the nanoparticle shape has been demonstrated. The dispersion curves presented for the TPP and Fabry-Perot mode are shown to be in good agreement with the spectra obtained by the transfer matrix method.

Ключевые слова (''Своб.индексиров.''): photonic crystal--nanocomposite--epsilon near-zero material--tamm plasmon polariton
Аннотация: Two schemes of excitation of a Tamm plasmon polariton localized at the interface between a photonic crystal and a nanocomposite with near-zero effective permittivity have been investigated in the framework of the temporal coupled-mode theory. The parameters of the structure have been determined, which correspond to the critical coupling of the incident field with a Tamm plasmon polariton and, consequently, ensure the total absorption of the incident radiation by the structure. It has been established that the spectral width of the absorption line depends on the scheme of Tamm plasmon polariton excitation and the parameters of a nanocomposite film. The features of field localization at the Tamm plasmon polariton frequency for different excitation schemes have been examined. It has been demonstrated that such media can be used as narrowband absorbers based on Tamm plasmon polaritons localized at the interface between a photonic crystal and a nanocomposite with near-zero effective permittivity.

Аннотация: The structure and magnetic properties of CoPt–Al2O3 nanocomposite films synthesized by the annealing of Al/(Co3O4 + Pt) bilayers on a MgO(001) substrate at 650°C in vacuum are investigated. The synthesized composite films contain ferromagnetic CoPt grains with an average size of 25–45 nm enclosed in a nonconducting Al2O3 matrix. The saturation magnetization (Ms ~ 330 G) and coercivity (Hc ≈ 6 kOe) of the films are measured in the film plane and perpendicular to it. The obtained films are characterized by a spatial rotational magnetic anisotropy, which makes it possible to arbitrarily set the easy magnetization axis in the film plane or perpendicular to it using a magnetic field stronger than the coercivity (H ˃ Hc).

Аннотация: Nanocomposite Fe–Al oxide catalysts were prepared by the melting of iron and aluminum nitrates with the subsequent calcination in air at different temperatures. It was found that the catalysts calcined at 450 °C are more active in the oxidation of CO than the catalysts calcined at 700 °C. X-ray diffraction and X-ray photoelectron spectroscopy showed that all the catalysts consist of hematite, α-Fe2O3 nanoparticles, and Al2O3 in an amorphous state. Iron oxide is the active component, which provides the oxidation of CO, while alumina is a texture promoter. The increase in the calcination temperature leads to a minor increase in the average size of hematite nanoparticles and an insignificant decrease in the specific surface area. Kinetic measurements showed that the oxidation of CO over the Fe–Al catalysts calcined at 450 and 700 °C proceeds with the activation energy of 61–69 and 91 kJ/mol, respectively. This means that the low-temperature and high-temperature catalysts contain different active species. Temperature-programmed reduction with CO indicated that the decrease in the calcination temperature improves the reducibility of the Fe-Al nanocomposites. According to 57Fe Mössbauer spectroscopy, the low-temperature catalysts contain hydrated iron oxides (acagenite and ferrihydrite) and a significant amount of highly defective hematite, which is absent in the high-temperature catalyst. These species can provide the enhanced activity of the low-temperature catalysts in the oxidation of CO.

Заглавие : In situ electron diffraction investigation of solid state synthesis of Co-In2O3 ferromagnetic nanocomposite thin films
Место публикации : JOM. - 2020. - Vol. 72, Is. 6. - P.2139–2145. - ISSN 10474838 (ISSN), DOI 10.1007/s11837-019-03919-5

Аннотация: In situ electron diffraction was used to study structural transformations during the formation of Co-In2O3 ferromagnetic nanocomposite thin films in a thermite reaction of In/Co3O4 bilayer thin films. Heating was performed from room temperature to 600°C at a rate of 4°C/min, while simultaneously electron diffraction patterns were recorded at a speed of 4 frames/min. This made it possible to determine the initiation, 185°C, and finishing, 550°C, temperatures of the solid-state synthesis, as well as the change in the phase composition during the thermite reaction. The synthesized Co-In2O3 film nanocomposite contained ferromagnetic cobalt nanoclusters surrounded by an In2O3 layer, with an average size of 20 nm, and had a magnetization of 400 emu/cm3 and a coercivity of 50 Oe at room temperature. The estimate of the effective interdiffusion coefficient of the reaction suggests that the main mechanism for the formation of the Co-In2O3 nanocomposite is diffusion along the grain boundaries and dislocations.

Ключевые слова (''Своб.индексиров.''): ferroelectric--phase transition--porous glass--nanocomposite
Аннотация: Heat capacity, thermal dilatation, sensitivity to pressure and permittivity of NH4HSO4 embedded into glass matrices with a pore size of 320 nm and 46 nm were studied. Large difference in the thermal expansion of both glass and ferroelectric leads to a "clamped" state of NH4HSO4 in nanocomposites and to the phase transition temperatures change. The restricted geometry does not effect on the order of successive transformations in NH4HSO4 but is accompanied by a significant reduction in entropy of phase transitions. The behavior of DTA-signal and permittivity show the expansion of the temperature range of the ferroelectric phase under hydrostatic pressure.

Ключевые слова (''Своб.индексиров.''): thermite reactions--reactive films--ferromagnetic nanocomposite films--al2o3
Аннотация: We have synthesized ferromagnetic nanocomposite Co-Al2O3 thin films via a thermite reaction between Al and Co3O4 with layer geometry. The starting Al/Co3O4 bilayers were obtained by the deposition of Al layers onto Co3O4 films at room temperature and were annealed at temperatures between 50 and 700 °C at 50 °C intervals. Above ∼450 °C the Co3O4 partially transformed into the CoO phase. The simultaneous solid-state reactions of Al with Co3O4 and Al with CoO started above the initiation temperature Tin ∼500 °C, which did not depend on the bilayer thickness. After annealing at 700 °C about 60% of the Co was reduced by the Al and the rest of the Co was contained in intermediate CoAl2O4 shells, which separated the Co nanoparticles from the Al2O3 matrix. Above 700 °C the reaction was complete and the final products were noninteracting Co nanoparticles with an average size of ∼40 nm enveloped by CoAl2O4 shells, which embedded into a dielectric Al2O3 matrix. The synthesized Co-Al2O3 nanocomposite films possessed soft magnetic behavior and good chemical stability.

Ключевые слова (''Своб.индексиров.''): photonic crystal--nanocomposite--optical tamm state
Аннотация: The spectral properties of a one-dimensional photonic crystal bounded with a resonance-absorbing nanocomposite layer are investigated. The bulk concentrations of metal nanoparticles dispersed in a transparent nanocomposite matrix are determined at which the effective permittivity takes near-zero values. The transmission, reflection and absorption spectra of the investigated structures at the normal incidence of light are calculated. The demonstrated possibility of formation of the optical Tamm states at the interface between the photonic crystal and nanocomposite is ensured by the near-zero real and imaginary parts of the permittivity or only the imaginary part of the permittivity at the zero real part. The specific features of field localization at the optical Tamm state frequencies are examined.

Ключевые слова (''Своб.индексиров.''): photonic crystal--nanocomposite--epsilon near zero material--tamm plasmon polariton
Аннотация: The spectral properties of a one-dimensional photonic crystal bounded by a resonant absorbing nanocomposite layer with the near-zero permittivity have been studied. The problem of calculating the transmittance, reflectance, and absorptance spectra of such structures at the normal and oblique incidence of light has been solved. It is shown that, depending on the permittivity sign near zero, the nanocomposite is characterized by either metallic or dielectric properties. The possibility of simultaneous formation of the Tamm plasmon polariton at the photonic crystal/metallic nanocomposite interface and the localized state similar to the defect mode with the field intensity maximum inside the dielectric nanocomposite layer is demonstrated. Specific features of field localization at the Tamm plasmon polariton and defect mode frequencies are analyzed. © 2018 by the authors.

Аннотация: The spectral properties of a one-dimensional photonic crystal bounded by an absorbing plasmonic gyroid layer are investigated. The gyroid material is a foam-like metallic three-dimensionally periodic curved film with zero mean curvature at every point. We calculate the transmittance and reflectance spectra at the normal and oblique light incidence. The possibility of the Tamm state formation at the interface between a photonic crystal and a plasmonic gyroid layer caused by the negative real part of the gyroid permittivity is demonstrated for the first time. Specific features of field localization at the Tamm state frequencies are discussed. It is shown that the spectral and polarization properties of the optical Tamm states are highly sensitive to the change in the angle of incidence and in the refractive index of a medium filling the gyroid cavities.

Аннотация: The results of structural and magnetic investigations of nanogranular Co–Al2O3 films formed from Co3O4/Al thin-film layered structures upon vacuum annealing are reported. The Co3O4/Al films have been obtained by sequential reactive magnetron sputtering of a metallic cobalt target in a medium consisting of the Ar + O2 gas mixture and magnetron sputtering of an aluminum target in the pure argon atmosphere. It is shown that such a technique makes it possible to obtain nanogranular Co–Al2O3 single- and multilayer thin films with a well-controlled size of magnetic grains and their distribution over the film thickness.

Аннотация: The influence of ultrasonic treatment on the strength and dielectric properties of composites based on ultra-high molecular weight polyethylene (UHMWPE) and multi-walled carbon nanotubes (MWCNT) is studied. It is revealed that the ultrasonic treatment of composite melt at 130 °C results in the uniform distribution of nanotubes in the UHMWPE matrix, an increase in the degree of composite crystallinity by 10%, an increase in abrasion resistance by 37%, an increase in elongation at rupture by a factor of 2. The change in the physical and mechanical properties of the composite is caused by the change in the polymer matrix structure, taking place as a result of ultrasonic action, and does not depend on the presence of nanotubes in the polymer matrix.
