Аннотация: The evolution of the magnetic properties of composite Al2O3/Co(P) particles during ball milling and dynamic compaction is investigated. To prepare starting composite particles, the Al2O3 granules were coated with a Co95P5 shell by electroless plating. The magnetic and structural properties of the composite particles are characterized by scanning electron microscopy, X-ray diffraction, and the use of the Physical Property Measurement System. The use of composite core-shell particles as starting powder for mechanoactivation allows to decrease treatment duration to 1 h and to produce a more homogeneous bulk sample than in the case of the mixture of Co and Al2O3 powders. The magnetic properties of the milled composite particles are correlated with changes in the microstructure. Reduction in grain size of Co during milling leads to an increase of the volume fraction of superparamagnetic particles and to a decrease of the saturation magnetization. The local magnetic anisotropy field depends on the amount of hcp-Co phase in sample. The anisotropy field value decreases from 8.4 kOe to 3.8 kOe with an increase in milling duration up to 75 min. The regimes of dynamic compaction were selected so that the magnetic characteristics-saturation magnetization and coercive field-remained unchanged. (C) 2014 AIP Publishing LLC.

Аннотация: The phase composition, structural parameters, and basic magnetic characteristics of BaFe12O19 hexaferrites prepared by the mechanochemical synthesis with subsequent annealing at a temperature of 1000°С and 1100°С for 1 h are investigated. The influence of the annealing temperature on the properties of synthesized materials is analyzed. Values of the saturation magnetization and the anisotropy field are determined. It is established that annealing temperature in the interval 1000 - 1100 °C does not significantly affect on the phase composition and the size of nanoparticles. The value of the anisotropy field increases substantially with increasing temperature.

Ключевые слова (''Своб.индексиров.''): mechanochemical synthesis--intermetallic compounds--gallium--iridium--complex compounds of iridium
Аннотация: The interaction between a solid inert metal (Ir) and an active liquid metal (Ga) during mechanical activation in a high-energy planetary mill is studied by X-ray diffraction and scanning electron microscopy with EDS-apparatus for high-resolution energy dispersive X-ray microanalysis. The influence of mechanical activation conditions on the formation of GaxIry intermetallic compounds and GaxIry/Ir composites and on their solubility in various acids is investigated. Being a surfactant for iridium, gallium propagates along the grain boundaries of polycrystalline iridium particles during mechanical activaiton and, hence, sharply decreases their strength. As a result of strong mechanical deformation during activation, the contact surface area between the solid and liquid metals, where the intermetallic compounds form intensely, increases sharply. As a result of treatment of the products of mechanical activaiton by a mixture of concentrated hydrochloric and nitric acids, iridium (30%) from passes into an acid solution and forms HxIrCly complex compounds, which can interact with bases to form soluble complex salts.

Аннотация: The mechanochemical route is a facile and fast way and has received much attention for developing versatile advanced functional materials. Herein, we reported a mechanochemical synthesis for incorporating divalent manganese ions (MnII) into a two-dimensional (2D) hybrid perovskite (C4H9NH3)2PbCl4. The mild external stimuli originating from the grinding at room temperature enabled the formation of MnII-doped 2D hybrid perovskites, and rapidly changed the luminescence characteristics. The photoluminescence analyses show that the violet and orange emissions are attributed to (C4H9NH3)2Pb1–xMnxCl4 band-edge emission and the T1→6A1 transition of Mn2+ resulting from an efficient energy transfer process, respectively. Site preference and distribution of the doped Mn2+ cations on the locations of Pb2+ were analyzed. The formation energy calculated by the density functional theory (DFT) indicates that the Mn2+ ions can rapidly enter the crystal lattice due to the unique 2D crystal structure of the hybrid perovskite. Such a case of mechanochemical synthesis for the 2D hybrid perovskite motivates many novel emerging materials and the related applications.

Аннотация: The core-shell Al2O3@Co particles were prepared by the ball-milling of the composite Al2O3-Co particles synthesized by electroless reduction. During the ball-milling process, both, the core-shell particle size and the ratio of hcp/fcc phases changed. To perform a phase analysis of the cobalt shell we used an approach based on the magnetic measurements. The use of Al2O3-Co composite particles as the precursors for the ball milling significantly shortens the time needed for a change in the phase composition of cobalt.

Аннотация: Luminescent trans-[Pb(DMTU-S)4Cl2] (DMTU: N,N′-dimethylthiourea) was designed and prepared via either mechanochemical or solvothermal methods, and the structures of DMTU and trans-[Pb(DMTU-S)4Cl2] have been resolved using X-ray single-crystal diffraction. Upon excitation over broadband covering the range from 450 to 250 nm, trans-[Pb(DMTU-S)4Cl2] shows yellow-green emission peaking at 549 nm with a spectral width of 110 nm, which is assigned to the triplet–singlet transition of Pb2+ ions within distorted heterogeneous S4Cl2 octahedra. The broadband excitation comprised singlet–singlet transitions of Pb2+ ions and energy transfer from orbitals involving those of organic ligands. Simultaneous analysis of the luminescent bandwidth and Stokes shift gives for Pb2+ ions in S4Cl2 octahedra the value of the Huang–Rhys parameter S = 4.25 and the energy of phonon involved in the formation of the luminescence spectrum of the order of 90 meV. Quantum yield as high as 91% is detected for excitation at 365 nm. This high quantum yield indicates the absence of noticeable concentration quenching at an average distance of 9.4 Å between the Pb2+ ions within the structure of trans-[Pb(DMTU)4Cl2]. The weak spin–orbit intersystem crossing is deduced from a high photoluminescence quantum yield (PLQY) value. Time dependent-density functional theory (TD-DFT) calculations of the nanocluster indicate the red shift of absorption bands in Pb(DMTU)4Cl2 with respect to parent DMTU. The high-performance photoluminescence and stability demonstrated promising applications in photonics.

Аннотация: The Sr1-xSmxTiO3 (х = 0.025, 0.05, 0.075, 0.1, 0.2) strontium titanate solid solutions were prepared from oxides and carbonates using a conventional ceramic technology based on the mechanochemical activation. The electrical conductivity and Seebeck coefficient of the synthesized compounds were measured in the temperature range from 300 to 800 K. We found that the properties of the samples significantly depend on the preliminary mechanochemical activation. The thermoelectric power factor attains maximum value in the hydrogen reduced samples with concentration of х = 0.05 and 0.075 obtained from nanoparticles: 5.5 μW/(cm · K2) for Sr0.95Sm0.05TiO3 (580 K) and 4.10 μW/(cm · K2) for Sr0.925Sm0.075TiO3 (650 K). An increase in the annealing temperature of mechanically activated samples leads to an even greater increase in electrical conductivity and power factor: 9.2 μW/(cm · K2) for Sr0.925Sm0.075TiO3 (650 K).
