Аннотация: The effect of the residual catalyst for the synthesis of multi-walled carbon nanotubes (MWCNTs) on the electrophysical properties of MWCNT-polyethylene composites produced by melt mechanical mixing was studied. The residual catalyst content was varied by changing the MWCNTs synthesis time. The nanotubes used in the work were characterized using transmission and scanning electron microscopy, atomic emission analysis, X-ray phase analysis, and magnetic permeability measurements. The structure of the synthesized composites was studied using optical and scanning electron microscopy. The dependences of the specific magnetization on the applied magnetic field, bulk electrical conductivity on the volumetric content of the filler in the composite, and the frequency dependences of the reflection, transmission, and absorption of electromagnetic radiation in the range 0.01-18 GHz were obtained. It was established that the obtained composites are characterized by a uniform distribution of nanotubes in the polymer matrix, and the dependence of the bulk electrical conductivity on the content of MWCNTs in the composite has a percolation character. Variation in the synthesis time of nanotubes allows producing MWCNTs with a high content of ferromagnetic particles, which are an alloy close in stoichiometry to the composition of the active component of the catalyst. It was shown that the use of composites modified with MWCNTs with a high content of residual catalyst is more effective for absorbing electromagnetic radiation due to an increase in their magnetic losses.

ε-Fe2O3 nanoparticles -- magnetic transition -- FMR spectra
Аннотация: The ϵ-Fe2O3 iron oxide polymorph is a well-known magnetic material with a complex magnetic structure, which undergoes a series of magnetic transitions in different temperature ranges. However, the ϵ-Fe2O3 phase diagram is still unclear. We report on the magnetic properties of a sample consisting of ϵ-Fe2O3 nanoparticles with an average size of 8 nm embedded in a SiO2 xerogel matrix without an admixture of foreign phases. Along with the features typical of the well-known ϵ-Fe2O3 magnetic transition in the temperature range 80–150 K, the temperature dependence of magnetization M(T) of ϵ-Fe2O3 includes other low-temperature anomalies. In an external field of H = 70 kOe, there is a noticeable temperature hysteresis of magnetization at 50–90 K, and near T ≈ 50 K, the M(T) curves have a characteristic bending, which may be indicative of an additional magnetic transition. The ferromagnetic resonance spectra shows that, near 500 K, a magnetic phase transition occurs, which was previously thought to be a transition to the paramagnetic state. An analysis of the temperature dependence of the ferromagnetic resonance spectra shows that the magnetically ordered phase in ϵ-Fe2O3 exists up to about 800 K.

Аннотация: Crystal structure of LaF3 single crystal is refined in tysonite-type trigonal unit cell P c1 using density functional theory calculations and Raman spectroscopy. It is shown that trigonal structure with P c1 space group is more energy-efficient than hexagonal structure with space group P63 cm. Simulated Raman spectra obtained using LDA approximation is in much better agreement with experimental data than that obtained with PBE and PBEsol functionals of GGA. The calculated frequency value of silent mode B 2 in case of hexagonal structure P63 cm was found to be imaginary (unstable mode), thus the energy surface obtains negative curvature with respect to the corresponding normal coordinates of the mode which leads to instability of the hexagonal structure in harmonic approximation. The A 1g line at 214 cm−1 in Raman spectra of LaF3 related to the translation of F2 ions along c axis can be connected with F2 ionic conductivity.

carbon nanomaterials -- platinum metal nanoparticles -- in situ one-step method
Аннотация: Carbon nanomaterials (fullerite, detonation nanodiamonds, Taunit, fullerenol, fullerene-containing black) were decorated with platinum group metal nanoparticles in situ in one step by low-temperature combustion (~250–270°С) of a powdered mixture of platinum metal acetylacetonate [Pt-M(асас)n, Pt-М = Pt(II), Pd(II), Rh(III), Ir(III), acac = CH3COCHCOCH3, n is the oxidation state of Pt-М] with carbon nanomaterials in air. As shown by thermal analysis, the process is based on thermal oxidative degradation of the organometallic complex, catalyzed by carbon nanomaterials, with oxidation (combustion) of the organic moiety and release of the metal into the condensed phase. The thermal process in an open system occurs in the glowing mode (210–250°С); the size of the nanoparticles formed is 7–30 nm. Under the conditions restricting the air access to the reaction mixture and free outflow of gaseous products formed by oxidation of acac ligands, the nanoparticle size decreases to 3–10 nm. The particle size depends on the metal amount in the initial powder mixture and on the support morphology.

Аннотация: It is shown that annealing 550°C of the Fe/Pt bilayer films fabricated by layer-by-layer deposition onto polycrystalline Al2O3 substrates in an atomic ratio of Fe: Pt = 71: 29 leads to the formation of the inplane rotational magnetic anisotropy with the easy axis that can be aligned by magnetic field in any direction in the film plane. The increase in the Pt content in the investigated film system to 50 at % leads to an increase in the anisotropy constant to 6.5 × 106 erg/cm3, which exceeds the value in the Fe71Pt29 sample by a factor of 6. In addition to the rotational anisotropy, the Fe50Pt50 films are characterized by the perpendicular rotational magnetic anisotropy, which is higher than the film shape anisotropy. Therefore, the easy axis in these samples can be aligned by magnetic field in any spatial direction. According to the X-ray and magnetic measurement data, the synthesized samples have a polycrystalline structure consisting of two ordered phases: magnetically hard L10–FePt and magnetically soft L12–Fe3Pt. This gives us grounds to suggest that the rotational magnetic anisotropy originates from the epitaxial intergrowth and exchange coupling of these two phases.

Аннотация: The magnetic properties of ferromagnetic nanodiscs coated with gold, manufactured using the Dip-Pen Nanolithography method, and were studied by atomic-force and magnetic force microscopy methods. The magnetic discs (dots) are represented as nanoagents (nanorobots) applied in medicine for the cancer cell destruction. The motivation of this work stem from the necessity of the understanding of the magnetization distribution in ferromagnetic discs that is crucial for their application in biomedicine. We have performed the theoretical calculations in order to compare the theoretical image contrast to experimental results. Herein, we report about the fabrication and analysis of biocompatible ferromagnetic nanodiscs with the homogenous magnetized state.

Аннотация: Density functional theory (DFT) and density functional tight binding (DFTB) molecular dynamics Density functional theory (DFT) and density functional tight binding (DFTB) molecular dynamics (DFTB/MD) simulations of embedding and relaxation of buckminsterfullerene C60 molecules chemisorbed on (001) and (111) surfaces and inside bulk silicon lattice were performed. DFT calculations of chemisorbed fullerenes on both surfaces show that the C60 molecule deformation was very small and the C60 binding energies were roughly ∼4 eV. The charge analysis shows that the C60 molecule charges on (001) and (111) surfaces were between −2 and −3.5 electrons, respectively, that correlates well with the number of C–Si bonds linking the fullerene molecule and the silicon surface. DFT calculations of the C60 molecule inside bulk silicon confirm that the C60 molecule remains stable with the deformation energy values of between 11 and 15 eV for geometries with different C60 configurations. The formation of some C–Si bonds causes local silicon amorphization and corresponding electronic charge uptake on the embedded fullerene cages. Charge analysis confirms that a single C60 molecule can accept up to 20 excessive electrons that can be used in practice, wherein the main charge contribution is located on the fullerene’s carbon atoms bonded to silicon atoms. These DFT calculations correlate well with DFTB/MD simulations of the embedding process. In this process, the C60 molecule was placed on the top of the Si(111) surface, and it was further exposed by a stream of silicon dimers, resulting in subsequent overgrowth by silicon.

Аннотация: We consider light-induced binding and motion of dielectric microparticles in an optical waveguide that gives rise to a backaction effect such as light transmission oscillating with time. Modeling the particles by dielectric slabs allows us to solve the problem analytically and obtain a rich variety of dynamical regimes both for Newtonian and damped motion. This variety is clearly reflected in temporal oscillations of the light transmission. The characteristic frequencies of the oscillations are within the ultrasound range of the order of 105 kHz for micron-size particles and injected power of the order of 100mW. In addition, we consider dynamics of a dielectric particle, driven by light propagating inside a Fabry-Perot resonator. These phenomena pave a way for optical driving and monitoring of the motion of particles in waveguides and resonators.

Аннотация: We consider light propagation above the light line in arrays of spherical dielectric nanoparticles. It is demonstrated numerically that quasi-bound leaky modes of the array can propagate both stationary waves and light pulses to a distance of 60 wavelengths at the frequencies close to the bound states in the radiation continuum. A semi-analytical estimate for decay rates of the guided waves is found to match the numerical data to a good accuracy. © 2016 Optical Society of America.
