Аннотация: Morphological parameters, reflection spectra, IR absorption spectra, and glass transition temperatures of submicron-sized spheres of poly(methyl methacrylate) (PMMA) formed in a water-acetone dispersion medium were studied in comparison with similar spheres obtained in distilled water. Dependence of a shrinkage degree of the submicrospheres on the concentration of acetone in water is studied. Features of the formation of periodic structures based on the water-acetone dispersions of PMMA in four different ways are considered. 2D (photonic crystal films) and 3D (artificial and inverse opals) resonance structures were obtained.

Аннотация: Polymer-based dielectric capacitors play a notable part in the practical application of energy storage devices. Graphene oxide (GO) nanosheets can improve the dielectric properties of polymer-based composites. However, the breakdown strength will greatly reduce with the increase of GO content. Hence, the construction of sandwich structure can enhance the breakdown strength without reducing the dielectric constant. Herein, single-layered and sandwich-structured poly(vinylidene fluoride-co-chlorotrifluoroethylene) (P(VDF-CTFE)) nanocomposites with low content of GO nanosheets (<1.0 wt%) are prepared via employing a straightforward casting method. Compared with the single-layered composites and pure P(VDF-CTFE), the sandwich-structured composites exhibit comprehensively better performance compared. The sandwich-structured composite with 0.4 wt% GO nanosheets show an excellent dielectric constant of 13.6 (at 1 kHz) and an outstanding discharged energy density of 8.25 J cm−3 at 3400 kV cm−1. These results demonstrate that the growth of the dielectric properties is owing to 2D GO nanosheets and the enhancement of breakdown strength due to the sandwich structure. The results from finite element simulation provide theoretical support for the design of high energy density composites.

Non-chemical fluorination of hexagonal boron nitride by high-energy ion irradiation / S. Entani [et al.] // Nanotechnology. - 2020. - Vol. 31, Is. 12. - Ст. 125705, DOI 10.1088/1361-6528/ab5bcc. - Cited References: 53 . - ISSN 0957-4484. - ISSN 1361-6528

Hexagonal boron nitride -- heteroatom doping -- high-energy ion irradiation -- near edge X-ray absorption fine structure -- ab initio calculation
Аннотация: Two-dimensional materials such as hexagonal boron nitride (h-BN) and graphene have attracted wide attention in nanoelectronics and spintronics. Since their electronic characteristics are strongly affected by the local atomic structure, the heteroatom doping could allows us to tailor the electronic and physical properties of two-dimensional materials. In this study, a non-chemical method of heteroatom doping into h-BN under high-energy ion irradiation was demonstrated for the LiF/h-BN/Cu heterostructure. Spectroscopic analysis of chemical states on the relevant atoms revealed that 6 ± 2% fluorinated h-BN are obtained by the irradiation of 2.4 MeV Cu2+ ions with the fluence up to 1014 ions/cm2. It was shown that the high-energy ion irradiation leads to a single-sided fluorination of h-BN by the formation of the fluorinated sp 3-hybridized BN.

core–shell nanoparticles -- iron oxides -- carbon shell -- Ag nanoparticles
Аннотация: Core–shell FexOy@C nanoparticles (NPs) modified with Ag were studied with x-ray diffraction, transmission electron microscopy, energy dispersive elemental mapping, Mössbauer spectroscopy, static magnetic measurements, and optical magnetic circular dichroism (MCD). FexOy@C NPs synthesized by the pyrolysis process of the mixture of Fe(NO3)3 centerdot 9H2O with oleylamine and oleic acid were added to a heated mixture of oleylamine and AgNO3 in different concentrations. The final product was a mixture of iron oxide crystalline NPs in an amorphous carbon shell and Ag crystalline NPs. The iron oxide NPs were presented by two magnetic phases with extremely close crystal structures: Fe3O4 and γ-Fe2O3. Ag is shown to form crystalline NPs located very close to the iron oxide NPs. An assumption is made about the formation of hybrid FexOy@C-Ag NPs. Correlations were obtained between the Ag concentration in the fabricated samples, their magnetic properties and the MCD spectrum shape. Introducing Ag led to a approximately linear decrease of the NPs saturation magnetization depending upon the Ag concentration, it also resulted into the MCD spectrum shift to the lower light wave energies. MCD was also studied for the Fe3O4@C NPs synthesized earlier with the same one-step process using different heat treatment temperatures, and MCD spectra were compared for two series of NPs. A possible contribution of the surface plasmon excitation in Ag NPs to the MCD spectrum of the FexOy@C-Ag NPs is discussed.

photonic crystal -- epicuticular wax -- density of photon states -- fluorescence
Аннотация: Wax is found on the leaves almost of all plants. Its physicochemical and protective properties are widely discussed in the scientific literature. In the presented work, the influence of the structure of wax on the optical properties in wheat leaves and needles of blue spruce has been revealed for the first time. Long-period ordering was established. The structural elements are nanotubes up to several microns in length and about 150 nm in diameter. The paper presents the influence of a long-period structure on the optical properties and local characteristics of light waves, including the transmission spectrum, the density of photon states, as well as fluorescence spectra and polarization microscopy. Using modern mathematical tools, the main spectral and optical characteristics were calculated using the example of the wax cover of blue spruce and glaucas wheat. Based on calculations that establish the relationship between the structural, spectral and optical properties, the influence of wax structures on the process of photosynthesis was revealed.

Аннотация: Backward electromagnetic waves are extraordinary waves with contra-directed phase velocity and energy flux. Unusual properties of the coherent nonlinear optical coupling of the phase-matched ordinary and backward electromagnetic waves with contra-directed energy fluxes are described that enable greatly-enhanced frequency and propagation direction conversion, parametrical amplification, as well as control of shape of the light pulses. Extraordinary transient processes that emerge in such metamaterials in pulsed regimes are described. The results of the numerical simulation of particular plasmonic metamaterials with hyperbolic dispersion are presented, which prove the possibility to match phases of such coupled guided ordinary and backward electromagnetic waves. Particular properties of the outlined processes in the proposed metamaterial are demonstrated through numerical simulations. Potential applications include ultra-miniature amplifiers, frequency changing reflectors, modulators, pulse shapers, and remotely actuated sensors.
